The federal Environmental Protection Agency (EPA) has delegated permit authority to state environmental agencies. In Washington, the NPDES-delegated permit authority is the Washington State Department of Ecology (Ecology). Municipalities with a population of over 100,000 (as of the 1990 census) have been designated as Phase I communities and must comply with Ecology’s Western Washington Phase I NPDES Municipal Stormwater Permit. With Puyallup’s 1990 census falling below the 100,000 threshold, the City must comply with the Western Washington Phase II Municipal Stormwater Permit. About 100 other municipalities in Washington must now comply with the Phase II Permit, along with Puyallup, as operators of small municipal separate storm sewer systems (MS4s). The Permit allows municipalities to discharge stormwater runoff from municipal drainage systems into the State’s waterbodies streams, rivers, lakes, wetlands) as long as municipalities implement programs to protect water quality by reducing the discharge of “non-point source” pollutants to the “maximum extent practicable” (MEP) through application of Permit-specified “best management practices” (BMPs). The practices specified in the Permit are collectively referred to as the Stormwater Management Program (SWMP) and grouped under the following components:  Public Education and Outreach  Public Involvement  Illicit Discharge Detection and Elimination  Controlling Runoff from Development, Redevelopment, and Construction Sites  Pollution Prevention and Municipal Operation and Maintenance  Monitoring The Permit requires the City to report annually (March 31st of each year) on progress in a Program implementation for the prior year. The Permit also requires submittal of documentation that describes proposed SWMP activities for the coming year. Implementation of various Permit conditions is phased throughout the five-year Permit term from February 16, 2007 through February 15, 2012. The Permit will be revised and reissued at the end of this period. A 2011 legislative change directed Ecology to reissue the existing Phase II permits unchanged for the period August 1, 2012 to July 31, 2013. A fully-updated Phase II NPDES municipal stormwater general permit will be issued with an effective date of August 1, 2013. This document is the City’s written documentation of the Stormwater Management Program Report The remainder of this 2012 document describes actions Puyallup will take to maintain compliance over ---PAGE BREAK--- 1: Introduction City of Puyallup 2012 1-2 the sixth year of the Permit term February 16, 2011 through February 16, 2012 plus one year for re- issuance, February 16, 2013). 1.2 Phased Permit Requirements Ecology began work on the Western Washington Phase II Municipal Stormwater Permit in the fall of 2004 and posted a preliminary draft for public comment on May 16, 2005. Ecology released a formal draft of the Permit in February 2006 and issued the final Permit on January 17, 2007. The permit was modified on June 17, 2009 to implement the outcomes of appeals. The Permit issued by Ecology became effective on February 16, 2007 and expires on February 15, 2012. Ecology is re-issuing the current permit for one additional year. The new expiration date for the re-issued permit will be February 15, 2013. Upon its expiration, a new permit will be revised and issued at the end of this period. Ecology is phasing in many of the Permit requirements over the five-year Permit term. On March 31 of each year, beginning in 2008, the City must: 1. Submit its to Ecology describing compliance activities planned for the coming year. 2. Submit an annual report documenting Permit compliance activities for the previous calendar year. 3. Post the and annual report on the web. This includes the following attachments:  Appendix A - Acronyms and Definitions from the Permit.  Appendix B - 2011 City of Puyallup City Future Stormwater Monitoring Plan  Appendix C - 2011 Effectiveness Monitoring Plan  Appendix D – 2012 Education and Outreach Plan The Western Washington Phase II Municipal Stormwater Permit and additional information can be found on Ecology’s website: http://www.ecy.wa.gov/Programs/wq/stormwater/municipal/phaseIIww/wwphiipermit.html. 1.3 Department Responsibilities The Permit requirements affect departments across the City organization. One difficulty in assigning lead departments to address Permit sections is that those sections do not divide cleanly along department divisional lines. To encourage collaboration and efficient use of resources, the City plans to charter implementation teams for each Permit component. These teams would consist of members from affected departments. Those departments include City Management (CM), Development Services Engineering, Information Technology (IT), Finance, Buildings, Public Works (PW), Legal, and Human Resources (HR). While the teams for each task may be cross-departmental, the lead department has been identified in the task tables for each Permit component in the following sections. 1.4 Total Maximum Daily Load (TMDL) Compliance Issues Stormwater discharges covered under the Permit are required to implement actions necessary to achieve the pollutant reductions called for in applicable Applicable are which have been approved by the EPA before the issuance date of the permit or which have been approved by the EPA prior to ---PAGE BREAK--- 1: Introduction City of Puyallup 2012 1-3 the date the permittee’s application is received by Ecology. Information on Ecology’s TMDL program is available on Ecology’s website at www.ecy.wa.gov/programs/wq/tmdl. All approved by EPA before February 15, 2006, were reviewed by Ecology to determine whether stormwater including municipal stormwater sources were identified in the TMDL. When most of these were developed, municipal stormwater was considered a subset of non-point discharges, rather than a permitted discharge. As a result, very few statewide contain requirements for municipal stormwater sources. Few completed to date have established load allocations or waste load allocations for municipal stormwater discharges covered under the Permit. Ecology is interpreting TMDL requirements as follows:  For where stormwater was not identified as a source of the pollutants of concern, or if all of the sources were defined in the TMDL, Ecology considers the MS4 not to be a significant contributor of pollutants.  Where stormwater was identified as a source of pollutants and the TMDL or implementation plans developed to support the TMDL identified control measures were less than or equivalent to the requirements of this permit, Ecology sets a narrative effluent limit: “compliance with the permit compliance constitutes compliance with the TMDL.”  If stormwater was identified as a source of pollutants and specific WLAs, LAs or control measures were established, Ecology must develop effluent limits in addition to the other requirements of the permit. These effluent limits may be narrative or numeric depending on the control measures set by the TMDL or implementation plans. Where a TMDL or the detailed implementation plan developed for the TMDL identifies actions or activities beyond what is required by this permit, Ecology has identified the additional requirements in Appendix 2 of the permit for all approved by EPA prior to February 15, 2006. Appendix 2 of the permit lists the cities and counties affected by the TMDL. The City of Puyallup has not been listed in Appendix 2. 1.5 Document Organization The content in this document is based upon Permit requirements and Ecology’s Draft Guidance for City and County Annual Reports for Western Washington Phase II Municipal Stormwater Permits. The remainder of the Stormwater Management Program document is organized similarly to the Permit:  Section 2.0 addresses Permit requirements for administration of the City’s Stormwater Management Program for 2012.  Section 3.0 addresses Permit requirements for Public Education and Outreach for 2012.  Section 4.0 addresses Permit requirements for Public Involvement and Participation for 2012.  Section 5.0 addresses Permit requirements for Illicit Discharge Detection and Elimination for 2012.  Section 6.0 addresses Permit requirements for Controlling Runoff from New Development, Redevelopment and Construction Sites for 2012.  Section 7.0 addresses Permit requirements for Pollution Prevention and Operation and Maintenance for Municipal Operations for 2012.  Section 8.0 addresses Permit requirements for the Water Quality Monitoring section of the Permit for 2012. Each section includes a summary of the relevant Permit requirements and a description of current and planned compliance activities. ---PAGE BREAK--- 2.

The purpose of the Stormwater Management Program is to reduce the discharge of pollutants from the municipal stormwater system to the maximum extent practicable (MEP) thereby protecting water quality. The Stormwater Management Program Report is to include the actions and activities described in Sections 3 through 8 of this  Submit annual reports beginning in 2008 to Ecology by March 31st (for the previous calendar year). These reports are to summarize SWMP implementation status and present information from assessment and evaluation activities conducted during the reporting period. 2.2 Current Activities The City currently has in place activities and programs that meet the Permit requirements. Current activities associated with the above Permit requirements include:  The City is on track to comply with Ecology’s requirements for submittal of the documentation by March 31, 2012. The Public Works Department, with the assistance of an internal Steering Committee, is currently leading City development of the future planned activities.  The City has set up the systems for tracking training (HR).  The City has defined its strategy for cost tracking (Finance).  The City is on track to comply with Ecology’s requirements for submittal of the fifth Annual Report and by March 31, 2012. 2.3 Planned Activities Puyallup has positioned itself well to maintain compliance as Ecology phases in the future Permit deadlines. Table 2-1 presents the proposed work plan for the 2012 administration activities. These tasks will continue to be refined through an iterative process of interviews and workshops with staff from affected City departments. ---PAGE BREAK--- 2.

The 2012 program is detailed in the ‘2012 City of Puyallup Stormwater Education and Outreach Plan.’ The plan outlines the outreach activities and programs the City will implement, contingent upon program and grant funding, in order to achieve measurable improvements in the various target audiences’ understanding of stormwater and ways to improve and protect water quality. Several of the activities and programs implemented prior to 2012 will be continued in the upcoming year including those current activities from 2011 outlined below:  Updating and management of the City’s Stormwater Management webpage. This includes: uploading new information and documents, adding public service announcements, important updates about stormwater education and outreach events, and the number for the City’s Illicit Discharge Hotline.  Implementation of Puyallup’s Rain Garden Program; during 2011 this program included the installation of 19 rain gardens, 8 rain barrels, and riparian planting along a TMDL-affected stream.  The City strives to include stormwater-related information in City publications when possible. For example, in 2011 both the spring and fall clean-up brochures included articles related to stormwater pollution prevention. In addition, the quarterly Puyallup Today newsletter often highlights events of the Stormwater Department.  Providing education and outreach as well as serving to improve water quality in our local streams, Silver Creek has been the focus of riparian restoration for the City for several years now. This past year, 2011, hosted five volunteer events at which several hundred native plants were installed, invasive weeds were cleared, and over 100 people learned of the importance of riparian zones, the impact we have on our waterways, and how they can help improve water quality in our streams, lakes and rivers. ---PAGE BREAK--- 3: Public Education and Outreach City of Puyallup 2012 3-2  Continued management of the Fish Friendly Car Wash Program  Purchase and distribution of car wash vouchers, as part of the Puget Sound Car Wash Association fish- friendly program. 3.3 Planned Activities The City plans to expand its Education and Outreach program in 2012 through the continued expansion of collaborative partnerships with local organizations and other permittees including involvement in the local EcoNet group, regional STORM group, and local SOG group as a subset of STORM. In addition, the City has recently been selected for an interagency agreement with Ecology that will bring the Local Source Control Program to the City. The City had previously adopted and incorporated the Puget Sound Starts Here logo on its catch basin markers and is continuing to integrate the branding on publications where possible, to build on the regional efforts to build a recognizable brand and message across jurisdictions.

The City’s current Permit does not include TMDL requirements because there were no EPA-approved affecting the City prior to the cut-off date (February 2006) for inclusion in the current Permit.  Any sampling or testing required for characterizing illicit discharges pursuant to the Permit’s Illicit Discharge Detection and Elimination (IDDE) conditions.  Preparation for future, comprehensive, long-term water quality monitoring efforts consistent with current Phase I monitoring requirements. According to the Permit, this program would include two components: 1) general stormwater quality monitoring and, 2) targeted Stormwater Management Program (SWMP) effectiveness monitoring. The stormwater monitoring is intended to characterize stormwater runoff quantity and quality at a limited number of locations. This characterization would allow for analysis of pollutants and changes in conditions over time and across the City. The SWMP effectiveness monitoring is intended to improve stormwater management efforts by evaluating various stormwater controls. Results of the monitoring will be used to support the adaptive management process for improving programs over time.  Identification of two outfalls where permanent stormwater sampling stations can be installed and operated for future monitoring (by the end of the Permit term and with the 4th Annual Report). The two outfalls must represent commercial, high-density residential, and industrial land uses. The monitoring shall include plans for stormwater, sediment or receiving water monitoring of physical, chemical, and/or biological characteristics.  Identification of two suitable SWMP Program questions and sites where targeted SWMP Program effectiveness monitoring can be conducted together with development of a monitoring plan for these questions and sites. The proposed effectiveness monitoring should be prepared to answer the following types of questions: • How effective is a specific targeted action or a narrow suite of actions? • Is the Stormwater Management Program achieving a targeted environmental outcome? In addition, the City is required to provide the following monitoring and/or assessment data in Annual Reports:  A description of stormwater monitoring or studies conducted by the City during the reporting period. If stormwater monitoring was conducted on behalf of the City, or if studies or investigations conducted by ---PAGE BREAK--- 8: Monitoring City of Puyallup 2012 8-2 other entities were reported to the City, a brief description of the type of information gathered or received shall be included in the Annual Report.  An assessment of the appropriateness of the best management practices identified by the City for components of the Stormwater Management Program; and changes made, or anticipated to be made, to the practices that were previously selected to implement the Stormwater Management Program and why those changes are desirable. 8.2 Current Activities The City, in partnership with the Puyallup Tribe and Department of Ecology, conducted a 15-month monitoring program for the Clarks Creek Watershed Pollution Reduction Project. The monitoring results were used to identify pollutant sources and estimate pollutant loads. The results of the monitoring are described in the Clarks Creek Watershed Pollution Reduction Project Submittal Report (URS and Brown and Caldwell, February 2005). 8.3 Planned Activities Puyallup will likely need to create a Water Quality Monitoring Program to maintain compliance during the next Permit term. Except for summarizing monitoring activities no actions are required until 2013. Table 8-1 presents the work plan for 2012 SWMP monitoring activities.

The Phase II Permit, issued in 2007 and modified in 2009, includes requirements for permittees to prepare to conduct a monitoring program in future permits. The Phase II Monitoring Program described in Section S8.C includes two types of monitoring: 4. Stormwater Monitoring (S8.C.1.a) 5. Stormwater Management Program (SWMP) Effectiveness Monitoring/Targeted SWMP Effectiveness Monitoring (S8.C.1.b) Stormwater Monitoring (S8.C.1.a) requires permittees to identify sites suitable for monitoring stormwater discharges based on jurisdictional size and land use types, and on known water quality problems and/or targeted areas of interest for future monitoring. SWMP Effectiveness Monitoring (S8.C.1.b) requires permittees to identify questions that monitoring may answer to determine the effectiveness of specific components of their Stormwater Management Program (SWMP). The permittee must identify sites for monitoring and create monitoring plans to answer at least two effectiveness questions. This document covers stormwater monitoring for Phase II Permit condition S8.C.1.a; effectiveness monitoring (S8.C.1.b) is described in a separate plan. 1.2 Future Phase II Permit Monitoring Requirements This monitoring plan was prepared to meet the requirements of the current (2007) Phase II Permit. However, the next Phase II Permit, which is scheduled to be issued in 2013, is expected to contain monitoring requirements substantially different from those envisioned in the current Permit. In 2008, Ecology convened the Puget Sound Stormwater Workgroup (SWG) to develop a comprehensive, sustainable, stormwater monitoring strategy for Puget Sound, as well as monitoring requirements for the next Phase I and Phase II permits. The SWG members represent caucuses of local, state, and federal agencies, environmental and business organizations, tribes and agriculture. The SWG submitted the comprehensive strategy in July 2010 to Ecology (in a document titled 2010 Stormwater Monitoring and Assessment Strategy for the Puget Sound Region). Based on this strategy, the SWG submitted monitoring recommendations for the next NPDES Phase I and II permits on October 29, 2010, in a document titled Recommendations for Municipal Stormwater Permit Monitoring). The SWG recommends that Ecology designate an independent entity to administer the stormwater-related monitoring and assessment activities in the next municipal stormwater permits. This recommendation is called the “pay-in” option. The SWG recommended receiving water monitoring rather than the outfall monitoring described in the current Phase II Permit. Moreover, the SWG recommended that the regional entity (rather than by each permittee) administer the program effectiveness monitoring and focus on questions of regional significance. ---PAGE BREAK--- B-4 More information on the SWG is available at http://www.ecy.wa.gov/programs/wq/psmonitoring/swworkgroup.html. The monitoring requirements will be substantially different from those envisioned in the current Permit. Thus, this monitoring plan should be regarded as tentative and subject to change based on the next Phase II Permit. As of the writing of this document, a definitive monitoring plan has not been established by Ecology. ---PAGE BREAK--- B-5 Section 2 Monitoring Site Selection Process 2.1 Land Use Requirements Puyallup has a population of 37,022 according to the 2010 US Census Bureau population data. Based on the thresholds set in Permit section S8.C.1.a, the City must select two outfalls where stormwater characterization monitoring could be conducted. One site should represent commercial land uses and the other should represent high-density residential land uses. In addition to the selecting outfalls which the land uses noted above, Ecology guidance recommends selecting locations where municipalities already have an interest in the receiving water quality. 2.2 Sampling Sites Selection The Phase II permit states that Permittees shall select outfalls or conveyances based on known water quality problems and/or targeted areas of interest for future monitoring, The City would like to highly consider locations where monitoring has been or is being conducted. This will allow monitoring collected as part of this proposal to build upon past or current monitoring information and to be used to identify trends and/or statistically significant changes. It also increases likelihood that the monitoring sites will be accessible and that power and other monitoring station needs are met. The City has been collecting monitoring data at many sites over the past 20 years and so it could be informative for the City if they could build on this existing data. Ecology’s May 2010 Monitoring and Reporting Guidance for Phase II Municipal Stormwater Permits (Publication 10-10-030) was also used to select outfalls or conveyances. The NPDES permit requires Permittees to document: Why sites were selected; Possible site constraints for installation of and access to monitoring equipment; A brief description of the contributing drainage basin including size in acreage, dominant land use, and other contributing land uses; Any water quality concerns (or interests) in the receiving water of each selected outfall or conveyance. The two potential monitoring sites are described below. Site 1 (Commercial): Puyallup River Outfall #14 Brief Description- The monitoring site is located at City outfall #14 near the skate park (see Figure It is a concrete pipe in line with 4th St NW and the Puyallup River. Reason for Selection- This site was selected due to its high concentration of commercial land use. Constraints- Flow from this outfall may be affected by backwater conditions during storm runoff events that coincide with Puyallup River flows above 17,000 cfs. However, this combination of conditions is expected to occur very infrequently. ---PAGE BREAK--- B-6 Brief Description of Contributing Drainage Basin (size, dominant land use, other contributing land uses)- The drainage basin is 138 acres. As shown in Table 1, over half of the basin is commercial. The rest of the basin is a combination of High Density Residential, Low Density Residential, Open Space, and Public Facilities. Table 1. Commercial Drainage Basin Characteristics Land Use Area (acres) Percent Commercial Auto Commercial 58.6 55% Pedestrian Oriented Commercial 3.8 High Density Residential 3.0 3% Low Density Residential 42.0 37% Open Space 0.0 0% Public Facilities 5.1 5% Water Quality Concerns or Interests- The Puyallup River, of the city limits (approximately two miles of outfall #14), is listed as “polluted” by fecal coliform bacteria. The fecal coliform listing is based on samples collected in 1998; however, samples collected in 2006 and 2008 did not exceed the state standards for fecal coliform. The same reach is listed as a “water body of concern” for dissolved oxygen. The reach about a third of a mile upstream h is listed as “polluted” due to elevated mercury concentrations. The City is unaware of any potential mercury source(s) in the outfall #14. drainage area. ---PAGE BREAK--- B-7 Figure 1. Commercial Land Use Basin Site 2 (High Density Residential): Clarks Creek Outfall #24 Brief Description- The monitoring site is located at the outfall pipe just of the Pioneer Ave bridge crossing over Clarks Creek. This 48-inch diameter concrete pipe receives stormwater runoff from an area that contains a mix of High Density Residential, Commercial, and Low Density Residential land uses (see Figure ---PAGE BREAK--- B-8 Reason for Selection- Using the City’s original land use data no basins were found to be dominated by High Density Residential land use. The City land use descriptions in the tax parcel data do not define the definition for Low Density Residential; however, using GIS analysis the average density of the Low Density Residential properties in this basin is 4-5 units per acre, which by the Ecology guidance would be defined as High Density Residential. The Pioneer Avenue drainage area was selected because it is an area of high importance due to planned economic redevelopment in the City’s downtown core. The selected sampling site will allow characterization of stormwater discharges into Clarks Creek, which has a TMDL for fecal coliform bacteria as well as sediment and dissolved oxygen concerns. Constraints- No known constraints. Brief Description of Contributing Drainage Basin (size, dominant land use, other contributing land uses)- The drainage basin encompasses 431 acres, including the right-of-way. Table 2 lists the current land use composition. As noted above, the area of High Density Residential is expected to increase as a result of the City’s economic redevelopment plan for the downtown area. The tables and figures are updated to use the Ecology, rather than City definition. Table 2. High Density Residential Drainage Basin Characteristics Land Use Area (acres) Percent Commercial Auto Commercial 3.5 17% Limited Commercial 2.2 Pedestrian Oriented Commercial 56.4 High Density Residential 198.8 56% Low Density Residential 27.5 8% Open Space 3.8 1% Public Facilities 62.8 18% Water Quality Concerns or Interests- Clarks Creek has a TMDL in place for fecal coliform. The Puyallup Tribe is developing a TMDL for dissolved oxygen in the creek. Excessive fine sediment and elodea growth are also key concerns for Clarks Creek. ---PAGE BREAK--- B-9 Figure 2. High Density Residential Land Use Basin ---PAGE BREAK--- B-10 Limitations The next version of the Phase II Permit may contain monitoring requirements that are substantially different from those envisioned in the current (2007) Permit. Therefore, the City may modify this plan after the next Phase II Permit has been issued. ---PAGE BREAK--- C-1 APPENDIX C 2012 Effectiveness Monitoring Plan ---PAGE BREAK--- C-2 CITY OF PUYALLUP FUTURE STORMWATER AND SWMP EFFECTIVENESS MONITORING PLAN Prepared by City of Puyallup Public Works Department December, 2011 ---PAGE BREAK--- C-3 Section 1 Monitoring Overview This section provides a brief overview of the monitoring requirements that are set forth in the Washington State Phase II Municipal Stormwater Permit for Western Washington (Phase II Permit). 1.1 Current Permit Monitoring Requirements The Phase II Permit regulates stormwater discharges for small municipal separate storm sewer systems (MS4s) as established in Title 40 CFR, part 122.26. The Phase II Permit, issued in 2007 and modified in 2009, includes requirements for permittees to prepare to conduct a monitoring program in future permits. The Phase II Monitoring Program described in Section S8.C includes two types of monitoring: 6. Stormwater Monitoring (S8.C.1.a) 7. Stormwater Management Program (SWMP) Effectiveness Monitoring/Targeted SWMP Effectiveness Monitoring (S8.C.1.b) Stormwater Monitoring (S8.C.1.a) requires permittees to identify sites suitable for monitoring stormwater discharges based on jurisdictional size and land use types, and on known water quality problems and/or targeted areas of interest for future monitoring. SWMP Effectiveness Monitoring (S8.C.1.b) requires permittees to identify questions that monitoring may answer to determine the effectiveness of specific components of their Stormwater Management Program (SWMP). The permittee must identify sites for monitoring and create monitoring plans to answer at least two effectiveness questions. This document covers effectiveness monitoring as required for S8.C.1.b; stormwater monitoring (S8.C.1.a) is described in a separate monitoring plan. 1.2 Future Permit Monitoring Requirements This monitoring plan was prepared to meet the requirements of the current (2007) Phase II Permit, as noted above. However, the next Phase II Permit, which is scheduled to be issued in 2013, may contain monitoring requirements substantially different from those envisioned in the current Permit. Thus, this monitoring plan should be regarded as tentative and subject to change based on the next Phase II Permit. In 2008, Ecology convened the Puget Sound Stormwater Workgroup (SWG) to develop a comprehensive, sustainable, stormwater monitoring strategy for Puget Sound, as well as monitoring requirements for the next municipal stormwater NPDES permits. The SWG members represent caucuses of local, state, and federal agencies, environmental and business organizations, tribes and agriculture. The SWG submitted the comprehensive strategy in July 2010 to Ecology (in a document titled 2010 Stormwater Monitoring and Assessment Strategy for the Puget Sound Region). Based on this strategy, the SWG submitted monitoring recommendations for the next NPDES Phase I and II permits on October 29, 2010, in a document titled Recommendations for Municipal Stormwater Permit Monitoring). The SWG recommends that Ecology designate an independent entity to administer the stormwater-related monitoring and assessment activities in the next municipal stormwater permits. This recommendation is called the “pay-in” option. The SWG recommended receiving water monitoring rather than the outfall monitoring described in the current permits. Moreover, the SWG recommended that the regional entity (rather than by each ---PAGE BREAK--- C-4 permittee) administer the program effectiveness monitoring and focus on questions of regional significance. As of the writing of this document, a definitive effectiveness monitoring plan has not been established by Ecology. More information on the SWG is available at http://www.ecy.wa.gov/programs/wq/psmonitoring/swworkgroup.html. ---PAGE BREAK--- C-5 Section 2 Targeted Stormwater Program Effectiveness Questions Phase II Permit condition S8.C.1.requires that each permittee prepare a monitoring plan to address two questions related to the effectiveness of the permittee’s stormwater management program. The monitoring plan must contain the following elements: A. A statement of the question, an explanation of how and why the issue is significant to the permittee and a discussion of whether and how the results of the monitoring may be significant to other MS4s. B. A specific hypothesis about the issue or management actions that will be tested. C. Specific parameters or attributes to be measured. D. Expected modifications to management actions depending on the outcome of hypothesis testing. The City’s proposed effectiveness questions and monitoring approach are described below. As noted above, the City understands that the next version of the Phase II Permit may contain monitoring requirements substantially different from those envisioned in the current Phase II Permit. The City may revise these effectiveness questions and/or monitoring strategies after the next Phase II Permit has been issued. Question 1- Will retrofitting alleys with porous pavement substantially reduce runoff? Problem Statement/Description: Creation of impervious surfaces has been identified as a major cause of the flooding, water pollution, and channel erosion problems that often accompany urbanization (National Academy of Sciences 2008). Porous pavement is designed to allow rainfall to infiltrate into the underlying soil, thereby minimizing surface runoff and related flooding, water pollution, and channel erosion problems. The City must devote substantial resources to meet NPDES flow and water quality control standards. Other MS4s are likely having similar issues. Hypothesis: Catchments with alleys covered by porous pavement will generate less surface runoff than catchments with alleys covered by traditional pavement. Specific parameters or attributes: The City will identify two small catchments with similar land uses, soils, and topography. The alleys in one of the catchments will be repaved using pervious material. The City will monitor runoff volumes from each catchment area and compare the results. Expected modifications: If monitoring determines that the areas with porous pavement substantially reduce runoff volumes then the City will more likely install porous pavement sections in alleys. Question 2- Will installation of rain gardens in road rights-of-way substantially reduce runoff? Problem Statement/Description: Nearly all of the existing roads in Puyallup are covered with impervious pavement. In some areas, road runoff is directed to adjacent grassy areas with limited potential for flow and pollutant attenuation. Installing rain gardens in these grassy areas could increase infiltration and sedimentation, thereby reducing flow volumes and pollutant loads. Rain gardens are low-lying, vegetated depressions with absorbent soils that promote infiltration. Rain gardens are a popular form of stormwater mitigation, as they are easy retrofits for existing developments and are well suited for small sites, such as rights-of-ways. ---PAGE BREAK--- C-6 Many other MS4s use rain gardens and therefore are likely to have similar questions regarding their effectiveness in reducing runoff from road rights-of-way. Hypothesis: Catchments with rain gardens in the rights-of-way will have less runoff than catchments with grass in the rights-of-way. Specific parameters or attributes: The City will identify two small catchments with grass-covered rights-of-way and similar land uses, soils, and topography. Rain gardens will be installed in the rights-of-way in one of the catchments. The City will monitor runoff volumes from each catchment area and compare the results. Expected modifications: If monitoring determines that the areas with rain gardens substantially reduce runoff volumes then the City may install more rain gardens in rights-of-ways in the City. ---PAGE BREAK--- D-1 APPENDIX D 2012 City of Puyallup Stormwater Education and Outreach Plan ---PAGE BREAK--- D-2 2012 City of Puyallup Stormwater Education and Outreach Plan Summary The Education and Outreach Plan provides an overview of the activities intended for the 2012 calendar year to meet requirements set forth in the NPDES Phase II for Education and Outreach (PE&O). All programs and activities will be implementing based on available funding, grants, and programs. Scope The following activities encompass the plan for educating the public, businesses, and City staff on the importance and impact of stormwater management, as well as the regulatory requirements that may pertain to citizens and business owners. Rain Gardens This program will continue into its 4th year in 2012. It is anticipated to utilize Ecology Capacity Grant funds, if available. Coordination with Pierce Conservation District Stream Team will continue, as well as expanding collaboration with local organizations with interest in the Clarks Creek and Puyallup watersheds. The 2012 program will seek to install 6-8 rain gardens and rain barrels in 2 neighborhood clusters. The City will focus at least one installation effort in the Clarks Creek basin. The program as a whole will include various LID elements, further detailed in sections below, such as: • Rain gardens • Permeable pavements • Rain barrels • Riparian planting Selection of cluster installation neighborhoods will be done on a self-nomination basis with homeowners. Program participants do not contribute to the cost of the rain gardens but will be asked to sign a maintenance agreement that will be recorded with Pierce County and attached to their property. Design and construction of the rain gardens and other included LID items will be done by the City and contractor(s). Final planting and mulching of the rain gardens will be done by volunteers on installation day. This culminating event will be presented as an environmental fair and neighborhood event that will include information booths from local Public Interest Groups, Environmental and Educational organizations, and related businesses. Porous Driveway Initiative This program may be implemented in conjunction with the Rain Garden Program, or developed as a stand-alone program – depending upon funding sources. This Initiative will build on the 2010 Pilot Project effort that installed a permeable paver driveway on a cost-share and donation basis at private home, as part of the 2010 Rain Garden Program. Goals for this program include: • Demonstration of LID technique(s) to homeowners ---PAGE BREAK--- D-3 • Reduce stormwater runoff volume and associated pollutant loading • Focus on Clarks Creek Basin Riparian/Streamside Plantings Efforts will continue on an as-opportunity-arises basis to install riparian/streamside plantings at private homes along Clarks and Meeker creeks. As funding allows, mailings will be distributed again in 2012 to offer free streamside planting. The program will include site visits, recommendations, planning support, and plantings. Porous Alley Initiative This program will build on the FY2010 Capacity grant funding of the Porous Alley Pilot Program. Funding from multiple grant sources will be sought to develop this program. It is intended to continue this program for several years, addressing the annual maintenance need of the City’s gravel-paved alleys as well as seeking to reduce pollutant runoff from these areas. Alleys in the Clarks Creek basin will be addressed first. Where and when possible, excavation of the existing alley and installation of the aggregate layers will be done by City crews. Installation of the porous asphalt overlay will be completed through the City’s paving contract. The goal of this program is to provide demonstration sites for porous asphalt as an LID technique in the community to increase the public, and local businesses understanding of its application and function. Stormwater Pollution Prevention Artwork Contest/Calendar Program The result of this program will be published promotional materials (calendars) with educational messages on stormwater pollution prevention including stormwater BMPs, LID, and stormwater pollution prevention. This program will provide education and outreach through its implementation, as well as develop materials for use in outreach. Keyed to the school calendar year, this program has the ability to be recycled every year, to produce updated material. Local Source Control Program Funding through an interagency agreement with Ecology, the City will tailor and implement the Local Source Control (LSC) Program in partnership with Ecology and in collaboration with other regional LSC Programs as well as supporting local organizations including WSU-Puyallup and the Washington Stormwater Center. This program will provide a focused educational program for local businesses, specifically small quantity generators of dangerous waste, to identify sources of pollution on business sites and adopt and implement good housekeeping BMPs. Fish Friendly Car Wash Program Implemented as a local-concern focus of the LSC Specialist and program, the City will work to develop the Fish Friendly Car Wash (FFCW) Program to include cooperation with local businesses to serve as points-of-presence and destinations for hosting community FFCW events. The program is used to not only prevent stormwater runoff pollution from car wash activities – such as fund- raising event – but also to educate the public on the effects of soap and other pollutants when they enter the stormwater system as well as ways to prevent this pollution. ---PAGE BREAK--- D-4 Private Catch Basin Marking To expand the reach and influence of the Only Rain Down the Drain catch basin marker program, the City will expand the program to include marking of storm drains on private property including areas such as the Puyallup Fair Grounds, South Hill Mall, and other businesses with significant visibility and foot traffic. Illicit Discharge, Detection, and Elimination (IDDE) Program Dissemination of IDDE awareness and education will again be an added focus to the City’s outreach and education program as part of other existing efforts. In addition, the IDDE message will be expanded further with the creation of a Local Source Control (LSC) position to deliver the message directly to local businesses. This position will also offer support to identify, control, reduce, or eliminate pollutant sources and stormwater runoff by offereing technical assistance and information on Best Management Practices (BMP’s). Educational Messages The goal of the 2012 Education and Outreach Plan is to deliver to the community various stormwater-related messages while inspiring specific actions that address pollution prevention, LID techniques and applications, stormwater management, and impacts to our local waterways. Each Education and Outreach Program will strive to incorporate the following messages and invoke actions: • The cumulative effort of individual citizens can create significant impacts/detriments to our waterways • Only Rain Down the Drain – general message • Fish Friendly Car Washing • Scoop Fido’s Poo • Streamside Landscaping • Don’t Feed the Ducks! • Plant a Rain Garden • Get Disconnected from the stormwater system • LID applications: permeable pavement, rain gardens, rain barrels, green roofs ---PAGE BREAK--- 25th St SE File Name: H:\jray\planning\shawEpioneerAnnexation.mxd (PDF) October 20, 2010 City of Puyallup Information Technology & Communications For the Planning Division 0 300 600 150 Feet SHAW RD EXTENSION SHAW RD 134TH AV E INTER AV 25TH ST SE 74TH ST E CT SE RAINIER ST Annexation Area City Limits Urban Growth Area Tax Parcels The map features are approximate and are intended only to provide an indication of said feature.

Elodea Pilot Project In July 2011, the City implemented a pilot project located in Clarks Creek, beginning at the 7th Ave SW bridge, extending 650 south within the creek. The goal of the pilot project was to evaluate the effective removal rate by hand-pulling elodea and other invasive weeds. The removal rate and effectiveness will be compared to the current manual cutting operation that the City has undertaken in cooperation with Pierce County since 1991. ---PAGE BREAK--- Volunteers were recruited to enter the creek and perform the hand/tool pulling of the weeds. Organized into groups of 2-6 volunteers, and done in 3-4 hour shifts, the project was completed in 5 days of in-stream work. In all, 25 volunteers turned out through the project week to help pull the weeds. Stormdrain Markings In 2011, the city of Puyallup and Pierce Stream Team partnered to place curb markers next to public storm drains within the city limits of Puyallup. The city of Puyallup purchased markers with the “Only Rain down the Drain” message to educate citizens of the impacts stormwater has on our local streams and water quality. Stream Team coordinated two weekend events and one group of volunteers to place the markers next to public storm drains. The city and Stream Team agreed on a goal to mark 1,000 storm drains in 2011. With three marking events between June and September, Stream Team completed the marking of 742 storm drains in targeted areas within the city. One factor to consider in the quantity of curb markers being placed is weather, as volunteers can only complete this activity when the pavement is dry.

Looking forward, the city of Puyallup will purchase more curb markers for the 2012 season and Stream Team will coordinate volunteer efforts to complete their marking goal. Puyallup Fair The Stormwater Department staffed the Pierce Stream Team booth at the Puyallup Fair on September 23, 2011. Staff provided information to fair-goers on stormwater pollution prevention, LID BMPs such as rain gardens, rain barrels, and permeable pavements, and answered questions and concerns on how citizens can do their part to protect and improve water quality in our local streams and river. Emergency Preparedness Fair City of Puyallup coordinated and hosted an Emergency Preparedness Fair November 5, 2011 at the Puyallup Fair Grounds. Over 1,000 people attended the fair to learn about preparedness measures including information from the stormwater department. Information presented included tips on preventative measures at home in regards to flooding, stormwater pollution sources and ways to prevent it, permeable pavements, rain gardens, Illicit Discharge, Detection, and Elimination (IDDE), and fish-friendly car washing. ---PAGE BREAK--- Media Coverage • KIRO 7 Radio • Ciscoe Morris was contracted to broadcast live from the September 10, 2011 Rain Garden Installation on 5th Ave/18th Street SW • Tacoma News Tribune / Puyallup Herald Articles • “Partnership at Clarks Creek gets national look” (May 11, 2011) • Editorial – “More Rain Gardens Should be Welcome in Puyallup” (February 16, 2011) • “Puyallup Rain Gardens Garner Award” (May 17, 2011) • “Rain Garden Beauty” (September 14, 2011) • “Karshner fifth graders install rain gardens” (September 28, 2011) • Living Puyallup, website ((June 23, 2011) – “Do You Want Your Own Puyallup Rain Garden?” • Sightline – Northwest Magazine • “Curbing Stormwater and Creating Communities - The Case for Low-Impact Development” (March 2011) • San Francisco Estuary Partnership (February 2011) - “Permeable in Puyallup” • This Old House Article (September 2011) - “One Week, Six Rain Gardens” • South Sound Magazine (October 2011) – “Evolving Northwest Landscapes, Rain Gardens Save Money, Time, and the Environment” • City Vision Magazine (September/October 2011) – “Bringin’ in the Rain, Puyallup Goes Hyperlocal to Manage Runoff” Total number of events: 29 ---PAGE BREAK--- Puya l lup Rive r Cl ar k s C re e k WWTP Puyallup River The map features are approximate and are intended only to provide an indication of said feature.

Article I. General Provisions 21.10.010 Title. This chapter shall be known as the “city of Puyallup stormwater management regulations” and may be so cited. (Ord. 2951 § 1 (Exh. 2010). 21.10.020 Purpose and scope. The purpose of this chapter is to ensure water quality standards and help protect receiving waters, and their beneficial uses, by establishing minimum requirements for measures that must be implemented to control the quantity and quality of stormwater that is produced or affected by development, redevelopment or construction site activity. The water quality standards include: Chapter 173-200 WAC, Water Quality Standards for Ground Waters of the State of Washington; Chapter 173-201A WAC, Water Quality Standards for Surface Waters of the State of Washington; and Chapter 173-204 WAC, Sediment Management Standards. The provisions of this chapter shall apply to all development, redevelopment and construction site activity that occurs within the incorporated area of the city of Puyallup. (Ord. 2951 § 1 (Exh. 2010). 21.10.030 Definitions. For the purposes of this chapter the following definitions describe the meaning of the terms used in this chapter: “Drainage manual administrator” means the plan approval authority. “Developer” means a person or entity that engages, or plans to engage, in development, redevelopment or construction site activity. “Local government(s)” shall mean or include the city of Puyallup. ---PAGE BREAK--- “Low impact development (LID)” is a stormwater management and land development strategy applied at the parcel and subdivision scale that emphasizes conservation and use of on-site natural features integrated with engineering, small-scale hydrological controls to more closely mimic pre-development hydrologic functions. LID techniques store, infiltrate and evaporate stormwater where it falls rather than collect and convey it to the surface water off site. LID techniques include, but are not limited to: maintenance of native soil and vegetation on site; protection of natural drainage patterns; reduction of impervious surfaces; restoration of disturbed top soil; and use of bioretention areas rain gardens), permeable surfaces, and green roofs. “NPDES Permit,” or the “National Pollutant Discharge Elimination System and state waste discharge general permit for discharges from small municipal separate storm sewers in western Washington” means the Phase II Western Washington Municipal Stormwater Permit administered by the Washington Department of Ecology under authority for the national program for issuing, modifying, revoking and reissuing, terminating, monitoring and enforcing permits and imposing and enforcing pretreatment requirements, under Sections 306, 402, 318 and 405 of the federal Clean Water Act, for the discharge of pollutants to surface waters of the state. “Plan approval authority” is the development services administrator or director, or his or her designee. “Should,” as used in the 2005 Stormwater Manual, means shall, unless the plan approval authority permits or allows otherwise. (Ord. 2951 § 1 (Exh. 2010). 21.10.040 Adoption of the 2005 Stormwater Manual. The city of Puyallup adopts the 2005 Washington State Department of Ecology Stormwater Management Manual for Western Washington (hereinafter, the 2005 Ecology Manual), Volumes I through V, including, but not limited to, all definitions, thresholds, minimum requirements, adjustment and variance criteria, supplemental guidelines, optional guidance, and appendixes and glossaries thereto (Publication Numbers 05-10-029 through 05-10-033), and the amendments to the 2005 Ecology Manual, which are set forth in Appendix 1 (hereinafter, Appendix 1) of the City of Puyallup Phase II Western Washington Municipal Stormwater Permit (hereinafter, Phase II Permit), as part of these stormwater regulations. To the extent that Appendix 1 and the 2005 Ecology Manual are inconsistent, Appendix 1 shall control. Collectively, the 2005 Ecology Manual and Appendix 1 shall be known as the 2005 Stormwater Manual. Any exemptions (set forth in Minimum Requirement No. 7 of Appendix 1) for flow control requirements, including, but not limited to, those for projects that discharge directly to, or indirectly through an MS4 to, a water listed in Appendix I-E of the Stormwater Management Manual for Western Washington (2005) or the reach of the Puyallup River that is adjacent to the city, shall be suspended and unavailable until the city, to its satisfaction, completes its stormwater comprehensive plan update, which is scheduled to commence in 2010, and the development services administrator or director, or his or her designee, determines that the exemptions for flow control requirements are warranted for development, redevelopment or construction site activity.

(Ord. 2951 § 1 (Exh. 2010). ---PAGE BREAK--- City of Puyallup City Future Stormwater Monitoring Plan Prepared for City of Puyallup, WA December, 2010 ---PAGE BREAK--- 2 Section 1 Monitoring Overview This section provides a brief overview of the monitoring requirements that are set forth in the Washington State Phase II Municipal Stormwater Permit for Western Washington (Phase II Permit). 1.1 Current Permit Monitoring Requirements The Phase II Permit regulates stormwater discharges for small municipal separate storm sewer systems (MS4s) as established in Title 40 CFR, part 122.26. The Phase II Permit, issued in 2007 and modified in 2009, includes requirements for permittees to prepare to conduct a monitoring program in future permits. The Phase II Monitoring Program described in Section S8.C includes two types of monitoring: 1. Stormwater Monitoring (S8.C.1.a) 2. Stormwater Management Program (SWMP) Effectiveness Monitoring/Targeted SWMP Effectiveness Monitoring (S8.C.1.b) Stormwater Monitoring (S8.C.1.a) requires permittees to identify sites suitable for monitoring stormwater discharges based on jurisdictional size and land use types, and on known water quality problems and/or targeted areas of interest for future monitoring. SWMP Effectiveness Monitoring (S8.C.1.b) requires permittees to identify questions that monitoring may answer to determine the effectiveness of specific components of their Stormwater Management Program (SWMP). The permittee must identify sites for monitoring and create monitoring plans to answer at least two effectiveness questions. This document covers stormwater monitoring for Phase II Permit condition S8.C.1.a; effectiveness monitoring (S8.C.1.b) is described in a separate plan. 1.2 Future Phase II Permit Monitoring Requirements This monitoring plan was prepared to meet the requirements of the current (2007) Phase II Permit. However, the next Phase II Permit, which is scheduled to be issued in 2012, may contain monitoring requirements substantially different from those envisioned in the current Permit. In 2008, Ecology convened the Puget Sound Stormwater Workgroup (SWG) to develop a comprehensive, sustainable, stormwater monitoring strategy for Puget Sound, as well as monitoring requirements for the next Phase I and Phase II permits. The SWG members represent caucuses of local, state, and federal agencies, environmental and business organizations, tribes and agriculture. The SWG submitted the comprehensive strategy in July 2010 to Ecology (in a document titled 2010 Stormwater Monitoring and Assessment Strategy for the Puget Sound Region). Based on this strategy, the SWG submitted monitoring recommendations for the next NPDES Phase I and II permits on October 29, 2010, in a document titled Recommendations for Municipal Stormwater Permit Monitoring). The SWG recommends that Ecology designate an independent entity to administer the stormwater- related monitoring and assessment activities in the next municipal stormwater permits. This recommendation is called the “pay-in” option. The SWG recommended receiving water monitoring rather than the outfall monitoring described in the current Phase II Permit. Moreover, the SWG recommended ---PAGE BREAK--- 3 that the regional entity (rather than by each permitee) administer the program effectiveness monitoring and focus on questions of regional significance. More information on the SWG is available at http://www.ecy.wa.gov/programs/wq/psmonitoring/swworkgroup.html. If the next Phase II Permit incorporates the SWG recommendations, the monitoring requirements will be substantially different from those envisioned in the current Permit. Thus, this monitoring plan should be regarded as tentative and subject to change based on the next Phase II Permit. ---PAGE BREAK--- 4 Section 2 Monitoring Site Selection Process 2.1 Land Use Requirements Puyallup has a population of 38,690 according to the April 1, 2009 value used for allocation of selected state revenues. Based on the thresholds set in Permit section S8.C.1.a, the City must select two outfalls where stormwater characterization monitoring could be conducted. One site should represent commercial land uses and the other should represent high-density residential land uses. In addition to the selecting outfalls which the land uses noted above, Ecology guidance recommends selecting locations where municipalities already have an interest in the receiving water quality. 2.2 Sampling Sites Selection The Phase II permit states that Permittees shall select outfalls or conveyances based on known water quality problems and/or targeted areas of interest for future monitoring, The City would like to highly consider locations where monitoring has been or is being conducted. This will allow monitoring collected as part of this proposal to build upon past or current monitoring information and to be used to identify trends and/or statistically significant changes. It also increases likelihood that the monitoring sites will be accessible and that power and other monitoring station needs are met. The City has been collecting monitoring data at many sites over the past 20 years and so it could be informative for the City if they could build on this existing data. Ecology’s May 2010 Monitoring and Reporting Guidance for Phase II Municipal Stormwater Permits (Publication 10-10-030) was also used to select outfalls or conveyances. The NPDES permit requires Permittees to document: 1. Why sites were selected; 2. Possible site constraints for installation of and access to monitoring equipment; 3. A brief description of the contributing drainage basin including size in acreage, dominant land use, and other contributing land uses; 4. Any water quality concerns (or interests) in the receiving water of each selected outfall or conveyance. The two potential monitoring sites are described below. Site 1 (Commercial): Puyallup River Outfall #14 Brief Description- The monitoring site is located at City outfall #14 near the skate park (see Figure It is a concrete pipe in line with 4th St NW and the Puyallup River. Reason for Selection- This site was selected due to its high concentration of commercial land use. Constraints- Flow from this outfall may be affected by backwater conditions during storm runoff events that coincide with Puyallup River flows above 17,000 cfs. However, this combination of conditions is expected to occur very infrequently. ---PAGE BREAK--- 5 Brief Description of Contributing Drainage Basin (size, dominant land use, other contributing land uses)- The drainage basin is 138 acres. As shown in Table 1, over half of the basin is commercial. The rest of the basin is a combination of High Density Residential, Low Density Residential, Open Space, and Public Facilities. Table 1. Commercial Drainage Basin Characteristics Land Use Area (acres) Percent Commercial Auto Commercial 58.6 55% Pedestrian Oriented Commercial 3.8 High Density Residential 3.0 3% Low Density Residential 42.0 37% Open Space 0.0 0% Public Facilities 5.1 5% Water Quality Concerns or Interests- The Puyallup River of the city limits (approximately two miles of outfall #14) is listed as “polluted” by fecal coliform bacteria. The fecal coliform listing is based on samples collected in 1998; however, samples collected in 2006 and 2008 did not exceed the state standards for fecal coliform. The same reach is listed as a “water body of concern” for dissolved oxygen. The reach about a third of a mile upstream h is listed as “polluted” due to elevated mercury concentrations. The City is unaware of any potential mercury source(s) in the outfall #14. drainage area. ---PAGE BREAK--- 6 Figure 1. Commercial Land Use Basin Site 2 (High Density Residential): Clarks Creek Outfall #24 Brief Description- The monitoring site is located at the outfall pipe just of the Pioneer Ave bridge crossing over Clarks Creek. This 48-inch diameter concrete pipe receives stormwater runoff from an area that contains a mix of High Density Residential, Commercial, and Low Density Residential land uses (see Figure Reason for Selection- Using the City’s original land use data no basins were found to be dominated by High Density Residential land use. The City land use descriptions in the tax parcel data do not define the ---PAGE BREAK--- 7 definition for Low Density Residential; however, using GIS analysis the average density of the Low Density Residential properties in this basin is 4-5 units per acre, which by the Ecology guidance would be defined as High Density Residential. The Pioneer Avenue drainage area was selected because it is an area of high importance due to planned economic redevelopment in the City’s downtown core. The selected sampling site will allow characterization of stormwater discharges into Clarks Creek, which has a TMDL for fecal coliform bacteria as well as sediment and dissolved oxygen concerns. Constraints- No known constraints. Brief Description of Contributing Drainage Basin (size, dominant land use, other contributing land uses)- The drainage basin encompasses 431 acres, including the right-of-way. Table 2 lists the current land use composition. As noted above, the area of High Density Residential is expected to increase as a result of the City’s economic redevelopment plan for the downtown area. The tables and figures are updated to use the Ecology, rather than City definition. Table 2. High Density Residential Drainage Basin Characteristics Land Use Area (acres) Percent Commercial Auto Commercial 3.5 17% Limited Commercial 2.2 Pedestrian Oriented Commercial 56.4 High Density Residential 198.8 56% Low Density Residential 27.5 8% Open Space 3.8 1% Public Facilities 62.8 18% Water Quality Concerns or Interests- Clarks Creek has a TMDL in place for fecal coliform. The Puyallup Tribe is developing a TMDL for dissolved oxygen in the creek. Excessive fine sediment and elodea growth are also key concerns for Clarks Creek. ---PAGE BREAK--- 8 Figure 2. High Density Residential Land Use Basin ---PAGE BREAK--- 9 Limitations The next version of the Phase II Permit may contain monitoring requirements that are substantially different from those envisioned in the current (2007) Permit. Therefore, the City may modify this plan after the next Phase II Permit has been issued. ---PAGE BREAK--- IDDE SR-1 Illicit Discharge Detection / Guidance Side A FOLLOW Spill Response Plan (SR-1) (see reverse side) CONTAINER of unknown or hazardous materials left in the Right of Way or on City Property INTENTIONAL DUMPING or release to Soils, Surface Water, Storm Drainage or Sanitary Sewer ACCIDENTAL SPILL or release to Soils, Surface Water, Storm Drainage or Sanitary Sewer OR OR Dirty or discolored water flowing in a gutter line, swale or roadside ditch OR ANY water flowing in a gutter line, swale or roadside ditch during DRY WEATHER Call Public Works daytime [PHONE REDACTED] after hours [PHONE REDACTED] START HERE INCIDENT CONTINUED ON REVERSE SIDE F:\Yards\Storm Water\NPDES Road Map\Annual Reports\2010\SR1_IDDE_Spill Response_first responder_decision tree.xls rev 2-7-2011 ---PAGE BREAK--- Supervisors Radio # Office Cell Home Collections Donald Keith Henry 4401 [PHONE REDACTED] [PHONE REDACTED] [PHONE REDACTED] Ken Davies 4701 [PHONE REDACTED] [PHONE REDACTED] [PHONE REDACTED] 4901 [PHONE REDACTED] [PHONE REDACTED] [PHONE REDACTED] 4902 [PHONE REDACTED] Manager Rob Andreotti 4003 [PHONE REDACTED] [PHONE REDACTED] [PHONE REDACTED] Director Jim Morris 4001 [PHONE REDACTED] [PHONE REDACTED] [PHONE REDACTED] POTW Parks Don Lange Side B Street Water Craig Hale SPILL RESPONSE First Responder / Guidance SR-1 YES CALL PUBLIC WORKS [PHONE REDACTED] or [PHONE REDACTED] after hours NO Is the substance Hazardous?

Definitions not provided from the Permit were taken from other sources, including the Washington Department of Ecology Stormwater Management Manual for Western Washington, EPA NPDES website glossary, and the Illicit Discharge Detection and Elimination, A Guidance Manual for Program Development and Technical Assessments. Best management practices (BMPs) are the schedules of activities, prohibitions of practices, maintenance procedures, and structural and/or managerial practices approved by the Department of Ecology (Ecology) that, when used singly or in combination, prevent or reduce the release of pollutants and other adverse impacts to waters of Washington State. Combined sewer means a sewer that has been designed to serve as a sanitary sewer and a storm sewer, and into which inflow is allowed by local ordinances. Discoloration is a means by which to characterize stormwater. Typically, stormwater is yellowish in color. However, discoloration other than turbidity can indicate whether there is rust from iron pipes or iron bacteria, as seen by a yellowish/red color, or if paint or cleaning agent emulsions have entered the stormwater system, as indicated by a white cloudy color. Erosion and sediment control BMPs are BMPs that are intended to prevent erosion and sedimentation, such as preserving natural vegetation, seeding, mulching and matting, plastic covering, and sediment traps and ponds. Erosion sediment control BMPs are synonymous with stabilization and structural BMPs. Floatables is a means by which to characterize stormwater. A floatable is used as an indicator if very obvious trash or other controllable debris, such as landscaping material, leaf litter, etc. has entered into the storm system. Foam is a means by which to characterize stormwater. Foam is used as an indicator that potentially soap or other cleaning products have entered into the storm system. However, stormwater can often be foamy from pollen and other natural organic material. The way to tell the difference is by touch and smell. If the foam is persistent and accompanied by a fragrant odor, it is probably coming from a cleaning product. If the suds break up quickly, then it is probably from turbulence and/or natural conditions. Hazardous substance: Any material that poses a threat to human health and/or the environment. Typical hazardous substances are toxic, corrosive, ignitable, explosive, or chemically reactive. Any substance designated by the U.S. Environmental Protection Agency (EPA) to be reported if a designated quantity of the substance is spilled in the waters of the United States or is otherwise released into the environment. Hyperchlorinated means water that contains more than 10 mg/L chlorine. Disinfection of water mains and appurtenances requires a chlorine residual of 10 mg/L at the end of the disinfection period. This level is well above the Maximum Residual Disinfectant Level of an annual average of 4 mg/L chlorine for potable water. Illegal dumping means any intentional and non-permitted disposal of any substance other than stormwater into the municipal separate storm sewer system, unless otherwise called out as an allowed non-stormwater discharge. Illicit connection means any manmade conveyance that is connected to a municipal separate storm sewer without a permit, excluding roof drains and other similar type connections. Examples include sanitary sewer ---PAGE BREAK--- List of Definitions Stormwater Pollution Prevention Plan vi F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Parks FINAL.doc connections, floor drains, channels, pipelines, conduits, inlets, or outlets that are connected directly to the municipal separate storm sewer system. Illicit discharge means any discharge to the municipal separate storm sewer that is not composed entirely of stormwater except discharges pursuant to a National Pollutant Discharge Elimination System (NPDES) permit (other than the NPDES permit for discharges from the municipal separate storm sewer) and discharges resulting from fire fighting activities. Industrial Stormwater General Permit (ISGP) means the NPDES Industrial Stormwater General Permit, issued by Ecology for stormwater discharges associated with industrial activities (issued 2002, modified 2004, effective January 2005). Material storage facilities are uncovered areas where bulk materials (liquid, solid, granular, etc.) are stored in piles, barrels, tanks, bins, crates, or by other means. Municipal Separate Storm Sewer System (MS4) means a conveyance, or system of conveyances (including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, manmade channels, or storm drains) that meets the following criteria: i. Owned or operated by a state, city, town, borough, county, parish, district, association, or other public body (created by or pursuant to state law) having jurisdiction over disposal of wastes, stormwater, or other wastes, including special districts under state law such as a sewer district, flood control district or drainage district, or similar entity, or an Indian tribe or an authorized Indian tribal organization, or a designated and approved management agency under Section 208 of the federal Clean Water Act (CWA) that discharges to waters of the United States. ii. Designed or used for collecting or conveying stormwater. iii. Is not a combined sewer. iv. Is not part of a Publicly Owned Treatment Works (POTW) as defined at 40 CFR 122.2. National Pollutant Discharge Elimination System (NPDES) means the national program for issuing, modifying, revoking, and reissuing, terminating, monitoring, and enforcing permits, and imposing and enforcing pretreatment requirements, under Sections 307, 402, 318, and 405 of the federal Clean Water Act, for the discharge of pollutants to surface waters of the state from point sources. These permits are referred to as NPDES permits and, in Washington State, are administered by Ecology. Non-stormwater discharges are discharges of process wastewaters, vehicle wash waters, cooling waters, or any other wastewaters associated with the facility into the stormwater collection system. Other discharges must be addressed in a separate NPDES permit (EPA). See also Illicit discharges. Certain non-stormwater discharges are conditionally approved under the ISGP but are subject to specific provisions, including identifying the location, flow volumes, quality, potential for water quality issues, and ability to apply appropriate BMPs. Examples of conditionally approved non-stormwater discharges under an ISGP include the following:  discharges from firefighting activities  fire protection system flushing, testing, and maintenance  discharges of potable water including water line flushing, provided that water line flushing must be de-chlorinated prior to discharge  uncontaminated air conditioning or compressor condensate  irrigation drainage  uncontaminated groundwater or spring water ---PAGE BREAK--- List of Definitions Stormwater Pollution Prevention Plan vii F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Parks FINAL.doc  discharges associated with dewatering of foundations, footing drains, or utility vaults where flows are not contaminated with process materials such as solvents. Incidental windblown mist from cooling towers that collects on rooftops or areas adjacent to the cooling tower. This does not include intentional discharges from cooling towers such as piped cooling tower blow down or drains. Odor is a means by which to characterize stormwater. Contaminants in stormwater can give off specific odors, which should be described as accurately as possible. Odors can include rotten eggs, solvent, fuel/oil, cleaning agent, etc. When noting odors, make sure the odor is not related to other sources beyond the runoff being inspected. If gasoline or a flammable solvent is suspected, leave the immediate area, notify facility management immediately, and take action to prevent a fire or explosion. Operational source control BMPs are schedules of activities, prohibition of practices, and other managerial practices to prevent or reduce pollutants from entering stormwater. Operational BMPs include formation of a pollution prevention team, good housekeeping, preventive maintenance procedures, spill prevention and cleanup, employee training, inspections of pollutant sources and BMPs, and record-keeping. They can also include process changes, raw material/product changes, and recycling wastes. Outfall means a point source as defined by 40 CFR 122.2 at the point where a municipal separate storm sewer discharges to waters of the state and does not include open conveyances connecting two municipal separate storm sewer systems, or pipes, tunnels, or other conveyances which connect segments of the same stream or other waters of the state and are used to convey waters of the state. Runoff is water that travels across the land surface and discharges to water bodies either directly or through a collection and conveyance system (see also Stormwater). Run-on is stormwater runoff from another entity/jurisdiction or another area of the property that is not subject to the provision at issue. Sediment/erosion-sensitive feature means an area subject to significant degradation due to the effect of construction runoff or areas requiring special protection to prevent erosion. Sheen is used as an indicator in stormwater flows of petroleum products. Sheen looks like a rainbow hue on the water surface, and is commonly indicative of petroleum products, often present from parking lot runoff. Significant material includes, but is not limited to, raw materials; fuels; materials such as solvents, detergents, and plastic pellets; finished materials such as metallic products; raw materials used in food processing or production; hazardous substances designated under Section 101 (14) of CERCLA; any chemical the facility is required to report pursuant to Section 313 of Title III of SARA; fertilizers; pesticides; and waste products such as ashes, slag, and sludge that have the potential to be released with stormwater discharges. Source control BMPs means a structure or operation that is intended to prevent pollutants from coming into contact with stormwater through physical separation of areas or careful management of activities that are sources of pollutants. The Western Washington Stormwater Management Manual separates source control BMPs into two types. Structural source control BMPs are physical, structural, or mechanical devices or facilities that are intended to prevent pollutants from entering stormwater. Operational BMPs are nonstructural practices that prevent or reduce pollutants from entering stormwater. Spill means a release, either accidental or intentional, of a non-stormwater material. Stormwater means runoff during and following precipitation and snowmelt events, including surface runoff and drainage. ---PAGE BREAK--- List of Definitions Stormwater Pollution Prevention Plan viii F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Parks FINAL.doc Stormwater Management Manual for Western Washington means the five-volume technical manual (Publications Nos. 99-11 through 99-15 for the 2001 version and Publication No. 05-10-029-033 for the 2005 version [the 2005 version replaces the 2001 version]) prepared by Ecology for use by local governments that contains BMPs to prevent, control, or treat pollution in stormwater. Stormwater Management Program (SWMP) means a set of actions and activities designed to reduce the discharge of pollutants from the regulated small MS4 to the maximum extent practicable and to protect water quality, and comprising the components listed in S5 of S6 of the Western Washington Phase II Municipal Stormwater Permit and any additional actions necessary to meet the requirements of applicable requirements. Structural source control BMPs are physical, structural, or mechanical devices or facilities that are intended to prevent pollutants from entering stormwater. Structural source control BMPs typically include the following practices:  enclosing and/or covering the pollutant source (building or other enclosure, a roof over storage and working areas, temporary tarp, etc.).  segregating the pollutant source to prevent run-on of stormwater, and to direct only contaminated stormwater to appropriate treatment BMPs. Treatment BMPs are intended to remove pollutants from stormwater. A few examples of treatment BMPs are wet ponds, oil/water separators (OWS), biofiltration swales, and constructed wetlands. Turbidity is a means by which to characterize stormwater. The dispersion or scattering of light in a liquid, caused by suspended solids and other factors, is commonly used as a measure of suspended solids in a liquid. Vehicle maintenance or storage facility means an uncovered area where any vehicles are regularly washed or maintained, or where at least 10 vehicles are stored. Water quality means the chemical, physical, and biological characteristics of water, usually with respect to its suitability for a particular purpose. Waters of the state include those waters as defined as “waters of the United States” in 40 CFR Subpart 122.2 within the geographic boundaries of Washington state and “waters of the state” as defined in Chapter 90.48 RCW, which include lakes, rivers, ponds, streams, inland waters, underground waters, salt waters, and all other surface waters and water courses within the jurisdiction of the state of Washington. . ---PAGE BREAK--- 1: Introduction Stormwater Pollution Prevention Plan 1-1 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Parks FINAL.doc STORMWATER POLLUTION PREVENTION PLAN 1. INTRODUCTION This section provides the background information for this Stormwater Pollution Prevention Plan including applicable permit requirements and the intended goals and objectives. This section also provides the limitations of this document. 1.1 Background This applies to the city of Puyallup’s (City) Parks facility (Facility) located at 1201 4th Street NW, Puyallup, Washington (see Figure 2-1). This identifies actions that Facility staff will take to comply with the terms and conditions of the Department of Ecology (Ecology)’s Western Washington Phase II Municipal Stormwater Permit (Phase II Permit). This was prepared in accordance with Phase II Permit condition S5.C.5.i, which requires the following activities:  implement nonstructural best management practices (BMPs) immediately after the is developed or updated  include a schedule for implementation of structural BMPs  inspect the effectiveness of BMPs periodically  conduct periodic visual inspection of discharges from the facility during wet and dry conditions  update the when major BMP and/or administrative role revisions occur. 1.2 Goals and Objectives This is intended to help the City satisfy the following goals:  implement and maintain BMPs that identify, reduce, eliminate, and/or prevent the discharge of stormwater pollutants  prevent violations of surface water quality, groundwater quality, or sediment management standards  eliminate the discharges of unpermitted process wastewater, domestic wastewater, non-contact cooling water, and other illicit discharges to stormwater drainage systems. To meet these goals, this takes the following actions:  identifies potential sources of stormwater pollution that could affect the quality of stormwater discharges associated with the Facility  evaluates the potential for stormwater contamination from the identified potential sources  identifies the stormwater BMPs that will be used at the Facility for the prevention and control of pollutants in stormwater discharges  identifies operations, maintenance, inspections, and record-keeping needed for these BMPs. The City has formed a Pollution Prevention (P2) team to oversee implementation of this The P2 team will annually review the and confirm its implementation. The P2 team is discussed in detail in ---PAGE BREAK--- 1: Introduction Stormwater Pollution Prevention Plan 1-2 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Parks FINAL.doc Section 3.2. The P2 team will modify the annually or more often if needed to reflect changing conditions at the Facility, such as new operations, Facility modifications, or BMPs. Appendix A contains the Revision Form, which will be completed when revisions are made. 1.3 Limitations Ecology has not yet developed a template or guidelines specifically for municipal facilities covered by the Phase II Permit. Therefore, this was modeled after the city of Mount Vernon’s Fir Street Maintenance Facility (Brown and Caldwell 2009), which Ecology has cited as an example on its Web page titled Resource for Stormwater Management Plan Elements: Pollution Prevention and Good Housekeeping for Municipal Operations, which is located at the address below: (http://www.ecy.wa.gov/programs/wq/stormwater/municipal/pollutionPREVENTION.html). This is organized to be easy to use and update. The main body contains useful information for those in charge of administering and documenting implementation of the plan. The appendices contain the most relevant information for City staff at the Parks facility. ---PAGE BREAK--- 2: Facility Assessment Stormwater Pollution Prevention Plan 2-1 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Parks FINAL.doc STORMWATER POLLUTION PREVENTION PLAN 2. FACILITY ASSESSMENT This section provides an overview of the Facility and its stormwater drainage system. 2.1 Overview of Facility and Operations The City’s Parks Facility is located at 1201 4th Street NW in Puyallup, Washington (see Figure 2-1). The Facility encompasses approximately 2.5 acres. The site is primarily covered with impervious surfaces. The City-owned Facility is bordered by a secure fence with one main entry point at the southwest corner of the site. Buildings on site include:  Parks administrative offices and storage building  Equipment Storage Building  Wood Shop  Facilities Shop  Storage Building  Bulb Storage Building  Wash Rack, and a  Storage Shed. 2.2 Facility Drainage Figure 2-2 shows the drainage features at the Facility. Runoff from the northwest portion of the Facility drains to a catch basin within a skateboard park west of the Site. Runoff from the rest of the site is collected in catch basins and routed to the City storm sewer on 4th Street west of the Site. The City storm sewer ultimately discharges to the Puyallup River. ---PAGE BREAK--- 2: Facility Assessment Stormwater Pollution Prevention Plan 2-2 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Parks FINAL.doc Figure 2-1.

BEST MANAGEMENT PRACTICES This section provides a description of best management practices (BMPs) that are recommended for the Facility. Stormwater BMPs include structures, activities, or practices intended to help prevent or reduce stormwater pollution. This section also discusses the Pollution Prevention (P2) team, training requirements, and the BMPs currently implemented at the site. 3.1 Facility BMPs Phase II Permit Section S5.i requires implementation of nonstructural and structural BMPs. To develop BMP recommendations for this we reviewed the Ecology (2005) stormwater manual as well as the city of Seattle and King County manuals to identify the potentially appropriate BMPs for each activity at the Facility. We identified the existing BMPs for each activity. We then developed the BMP recommendations presented in Table 3-1. The table lists the recommended BMPs for each activity and notes which BMPs are already being implemented. The BMPs are included as separate activity pullout sheets in Appendix B for ease of use in the field. Table 3-1 includes a combination of structural and nonstructural measures. The nonstructural measures include general good-housekeeping measures that apply throughout the Facility (sweeping, etc.), as well as measures tailored to a specific activity checking storage tanks for spills and leaks). The table also lists existing structural measures, such as the covered vehicle wash rack and oil-water separator (OWS). The OWS removes hydrocarbons and suspended solids from the vehicle wash rack to reduce the potential for problems in the sanitary sewer and wastewater treatment plant. The Phase II Permit prohibits most non-stormwater discharges. Non-stormwater discharges were not identified on the site. ---PAGE BREAK--- 3: Best Management Practices Stormwater Pollution Prevention Plan F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Parks FINAL.doc Table 3-1.

Employee training is an ongoing program, and will be provided for all existing employees on a regular basis and for all new employees when they begin work at the Facility. Training material content will include the information in this spill response procedures, and visual inspection procedures. ---PAGE BREAK--- 4: Monitoring (Visual Inspections) Stormwater Pollution Prevention Plan 4-1 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Parks FINAL.doc STORMWATER POLLUTION PREVENTION PLAN 4. MONITORING (VISUAL INSPECTIONS) The Phase II Permit requires that the prescribe periodic visual observation of discharges from the Facility to evaluate the effectiveness of BMPs (S5.C.5.i.). The stormwater BMP monitoring for the Facility will rely upon annual wet and dry weather visual inspections of discharge quality to indicate obvious or potential problems and an annual BMP evaluation. The wet weather inspection will help assess overall BMP performance. The dry weather inspection will help confirm that illicit discharges have been eliminated. Coupled with the other BMPs for the Facility, as discussed in Section 3, this approach should reduce the potential for adverse impacts on stormwater quality. 4.1 Drainage and Outfall Characteristics The locations recommended for the wet and dry weather visual inspections are MON-1 and MON-2. These locations are shown on Figure 2-2 and described below. • MON-1 is located at the catch basin at the northwestern corner of the storage building. It receives run off from the Wash Rack area. • MON-2 is located at the catch basin located in the skateboard park, west of the Facility. It receives run off from the outdoor material storage area, the street sweepings dumpster, and the de-icing fluid tank. 4.2 Wet and Dry Weather Visual Inspections Each monitoring location will be inspected twice each year, once during dry weather and once during a storm runoff event. Appendix C contains the inspection forms. A designated member of the P2 team will perform these inspections. Wet weather inspections means that discharges from the identified outfalls will be assessed during a significant rainfall event resulting in visible stormwater runoff and discharges from the site. Inspections are not required to be conducted outside of regular business hours or during unsafe conditions. Dry weather inspections should be conducted when no rain has occurred at the Facility for at least 24 hours prior to inspection. The person conducting the inspection should look for the indicators described below:  Floatables: Floatables indicate if obvious trash or other controllable debris, such as landscaping material, leaf litter, etc. has entered into the storm system.  Foam: Foam indicates that potentially soap or other cleaning products have entered into the storm system. However, stormwater can often be foamy from pollen and other natural organic material. One can determine the difference by inspecting appearance and smell. If the foam is persistent and accompanied by a fragrant odor, it could be related to a cleaning product. If the suds break up quickly, then it could be from turbulence and/or natural conditions. ---PAGE BREAK--- 4: Monitoring (Visual Inspections) Stormwater Pollution Prevention Plan F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Parks FINAL.doc  Sheen: Sheen, which also looks like a rainbow hue on the water surface, is commonly indicative of petroleum products, often present from parking lot runoff. If gasoline or a flammable solvent is suspected, the inspector should leave the immediate area, notify facility management immediately, and take action to prevent a fire or explosion.  Turbidity: Turbidity, which makes the water appear cloudy, is usually an indication of dirt or sediment in the water.  Odor: Certain contaminants in stormwater can give off specific odors, which should be described as accurately as possible. Odors can include those similar to rotten eggs, solvent, fuel/oil, cleaning agent, etc. When noting odors, the inspector should make sure that the odor is not related to sources other than beyond the runoff being inspected. If gasoline or a flammable solvent is suspected, the inspector should leave the immediate area, notify the Facility management immediately, and take action to prevent a fire or explosion (see spill response procedures in Section 5 of this  Discoloration: A red/orange color can indicate rust from iron pipes or iron bacteria. Other colors such as white could indicate paint or cleaning agent emulsions.  Flow: Note presence or discharge from each outfall. If flow is present, the approximate discharge rate should be indicated on the inspection form < 10 gpm, or >10 gpm). The inspector should note whether each indicator was present or absent at the time of inspection, and note the approximate magnitude for any indicators that were observed. 4.3 Annual BMP Evaluation Once each year, the P2 team will evaluate the BMPs at the Facility to determine if additional BMPs are needed or if current BMPs should be modified. The evaluation s should be performed using the Annual BMP Evaluation Form. A copy of this form is provided in Appendix D. 4.4 Revisions The should be revisited once per year and revised if needed to reflect any administrative changes change in P2 team members). In addition, the should be revised when significant changes occur that could affect stormwater quality and BMP needs. Appendix A contains a copy of the Revision Form. ---PAGE BREAK--- 5: Spill Response Stormwater Pollution Prevention Plan 5-1 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Parks FINAL.doc STORMWATER POLLUTION PREVENTION PLAN 5. SPILL RESPONSE 5.1 Spill Response Plan and Emergency Cleanup This section describes the Facility’s Spill Response Plan (SRP). The main objective of responding to pollutant spill events is to contain the spill in order to minimize detrimental impacts to the environment and life safety. This SRP is intended for the use by the city of Puyallup’s public works staff. In response to a spill, staff should take the following steps: 1. Call Manager Tom Mark at [PHONE REDACTED] 2. If an employee can identify the material, an employee may conduct spill containment and/or cleanup only if ALL of the following conditions are met:  Without jeopardizing safety, the employee is able to determine that the material is not a hazardous material.  The employee considers himself or herself prepared and trained to respond to the spill.  Appropriate spill containing materials are available. 3. If the material involved shows ANY indication of being hazardous (for example, flammable, corrosive, or dangerous in nature), employees should take the following steps: ACTION: If you cannot identify the product involved, STOP and follow these procedures: 1. Leave the immediate area where the product is located. 2. Prevent others from approaching the product. 3. Call the police and Fire Department by dialing 911. If an employee cannot identify the material, or determines that the material is hazardous, the employee should follow Spill Response Plan included in Appendix E, along with the corresponding Spill Response flow diagram included in Appendix F. 5.2 Location of Spill Kits A spill kit containing adsorbent materials is located in the equipment storage building. Spill kit materials are re-stocked after each use. ---PAGE BREAK--- 6: Record-keeping Stormwater Pollution Prevention Plan 6-1 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Parks FINAL.doc STORMWATER POLLUTION PREVENTION PLAN 6.

Definitions not provided from the Permit were taken from other sources, including the Washington Department of Ecology Stormwater Management Manual for Western Washington, EPA NPDES website glossary, and the Illicit Discharge Detection and Elimination, A Guidance Manual for Program Development and Technical Assessments. Best management practices (BMPs) are the schedules of activities, prohibitions of practices, maintenance procedures, and structural and/or managerial practices approved by the Department of Ecology (Ecology) that, when used singly or in combination, prevent or reduce the release of pollutants and other adverse impacts to waters of Washington State. Combined sewer means a sewer that has been designed to serve as a sanitary sewer and a storm sewer, and into which inflow is allowed by local ordinances. Discoloration is a means by which to characterize stormwater. Typically, stormwater is yellowish in color. However, discoloration other than turbidity can indicate whether there is rust from iron pipes or iron bacteria, as seen by a yellowish/red color, or if paint or cleaning agent emulsions have entered the stormwater system, as indicated by a white cloudy color. Erosion and sediment control BMPs are BMPs that are intended to prevent erosion and sedimentation, such as preserving natural vegetation, seeding, mulching and matting, plastic covering, and sediment traps and ponds. Erosion sediment control BMPs are synonymous with stabilization and structural BMPs. Floatables is a means by which to characterize stormwater. A floatable is used as an indicator if very obvious trash or other controllable debris, such as landscaping material, leaf litter, etc. has entered into the storm system. Foam is a means by which to characterize stormwater. Foam is used as an indicator that potentially soap or other cleaning products have entered into the storm system. However, stormwater can often be foamy from pollen and other natural organic material. The way to tell the difference is by touch and smell. If the foam is persistent and accompanied by a fragrant odor, it is probably coming from a cleaning product. If the suds break up quickly, then it is probably from turbulence and/or natural conditions. Hazardous substance: Any material that poses a threat to human health and/or the environment. Typical hazardous substances are toxic, corrosive, ignitable, explosive, or chemically reactive. Any substance designated by the U.S. Environmental Protection Agency (EPA) to be reported if a designated quantity of the substance is spilled in the waters of the United States or is otherwise released into the environment. Hyperchlorinated means water that contains more than 10 mg/L chlorine. Disinfection of water mains and appurtenances requires a chlorine residual of 10 mg/L at the end of the disinfection period. This level is well above the Maximum Residual Disinfectant Level of an annual average of 4 mg/L chlorine for potable water. Illegal dumping means any intentional and non-permitted disposal of any substance other than stormwater into the municipal separate storm sewer system, unless otherwise called out as an allowed non-stormwater discharge. Illicit connection means any manmade conveyance that is connected to a municipal separate storm sewer without a permit, excluding roof drains and other similar type connections. Examples include sanitary sewer connections, floor drains, channels, pipelines, conduits, inlets, or outlets that are connected directly to the municipal separate storm sewer system. Illicit discharge means any discharge to the municipal separate storm sewer that is not composed entirely of stormwater except discharges pursuant to a National Pollutant Discharge Elimination System (NPDES) permit (other than the NPDES permit for discharges from the municipal separate storm sewer) and discharges resulting from fire fighting activities. ---PAGE BREAK--- List of Definitions Stormwater Pollution Prevention Plan vi F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Public Works FINAL.docm Industrial Stormwater General Permit (ISGP) means the NPDES Industrial Stormwater General Permit, issued by Ecology for stormwater discharges associated with industrial activities (issued 2002, modified 2004, effective January 2005). Material storage facilities are uncovered areas where bulk materials (liquid, solid, granular, etc.) are stored in piles, barrels, tanks, bins, crates, or by other means. Municipal Separate Storm Sewer System (MS4) means a conveyance, or system of conveyances (including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, manmade channels, or storm drains) that meets the following criteria: i. Owned or operated by a state, city, town, borough, county, parish, district, association, or other public body (created by or pursuant to state law) having jurisdiction over disposal of wastes, stormwater, or other wastes, including special districts under state law such as a sewer district, flood control district or drainage district, or similar entity, or an Indian tribe or an authorized Indian tribal organization, or a designated and approved management agency under Section 208 of the federal Clean Water Act (CWA) that discharges to waters of the United States. ii. Designed or used for collecting or conveying stormwater. iii. Is not a combined sewer. iv. Is not part of a Publicly Owned Treatment Works (POTW) as defined at 40 CFR 122.2. National Pollutant Discharge Elimination System (NPDES) means the national program for issuing, modifying, revoking, and reissuing, terminating, monitoring, and enforcing permits, and imposing and enforcing pretreatment requirements, under Sections 307, 402, 318, and 405 of the federal Clean Water Act, for the discharge of pollutants to surface waters of the state from point sources. These permits are referred to as NPDES permits and, in Washington State, are administered by Ecology. Non-stormwater discharges are discharges of process wastewaters, vehicle wash waters, cooling waters, or any other wastewaters associated with the facility into the stormwater collection system. Other discharges must be addressed in a separate NPDES permit (EPA). See also Illicit discharges. Certain non-stormwater discharges are conditionally approved under the ISGP but are subject to specific provisions, including identifying the location, flow volumes, quality, potential for water quality issues, and ability to apply appropriate BMPs. Examples of conditionally approved non- stormwater discharges under an ISGP include the following:  discharges from firefighting activities  fire protection system flushing, testing, and maintenance  discharges of potable water including water line flushing, provided that water line flushing must be de- chlorinated prior to discharge  uncontaminated air conditioning or compressor condensate  irrigation drainage  uncontaminated groundwater or spring water  discharges associated with dewatering of foundations, footing drains, or utility vaults where flows are not contaminated with process materials such as solvents. Incidental windblown mist from cooling towers that collects on rooftops or areas adjacent to the cooling tower. This does not include intentional discharges from cooling towers such as piped cooling tower blow down or drains. Odor is a means by which to characterize stormwater. Contaminants in stormwater can give off specific odors, which should be described as accurately as possible. Odors can include rotten eggs, solvent, fuel/oil, cleaning agent, etc. When noting odors, make sure the odor is not related to other sources beyond the runoff being inspected. If gasoline or a flammable solvent is suspected, leave the immediate area, notify facility management immediately, and take action to prevent a fire or explosion. ---PAGE BREAK--- List of Definitions Stormwater Pollution Prevention Plan vii F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Public Works FINAL.docm Operational source control BMPs are schedules of activities, prohibition of practices, and other managerial practices to prevent or reduce pollutants from entering stormwater. Operational BMPs include formation of a pollution prevention team, good housekeeping, preventive maintenance procedures, spill prevention and cleanup, employee training, inspections of pollutant sources and BMPs, and record-keeping. They can also include process changes, raw material/product changes, and recycling wastes. Outfall means a point source as defined by 40 CFR 122.2 at the point where a municipal separate storm sewer discharges to waters of the state and does not include open conveyances connecting two municipal separate storm sewer systems, or pipes, tunnels, or other conveyances which connect segments of the same stream or other waters of the state and are used to convey waters of the state. Runoff is water that travels across the land surface and discharges to water bodies either directly or through a collection and conveyance system (see also Stormwater). Run-on is stormwater runoff from another entity/jurisdiction or another area of the property that is not subject to the provision at issue. Sediment/erosion-sensitive feature means an area subject to significant degradation due to the effect of construction runoff or areas requiring special protection to prevent erosion. Sheen is used as an indicator in stormwater flows of petroleum products. Sheen looks like a rainbow hue on the water surface, and is commonly indicative of petroleum products, often present from parking lot runoff. Significant material includes, but is not limited to, raw materials; fuels; materials such as solvents, detergents, and plastic pellets; finished materials such as metallic products; raw materials used in food processing or production; hazardous substances designated under Section 101 (14) of CERCLA; any chemical the facility is required to report pursuant to Section 313 of Title III of SARA; fertilizers; pesticides; and waste products such as ashes, slag, and sludge that have the potential to be released with stormwater discharges. Source control BMPs means a structure or operation that is intended to prevent pollutants from coming into contact with stormwater through physical separation of areas or careful management of activities that are sources of pollutants. The Western Washington Stormwater Management Manual separates source control BMPs into two types. Structural source control BMPs are physical, structural, or mechanical devices or facilities that are intended to prevent pollutants from entering stormwater. Operational BMPs are nonstructural practices that prevent or reduce pollutants from entering stormwater. Spill means a release, either accidental or intentional, of a non-stormwater material. Stormwater means runoff during and following precipitation and snowmelt events, including surface runoff and drainage. Stormwater Management Manual for Western Washington means the five-volume technical manual (Publications Nos. 99-11 through 99-15 for the 2001 version and Publication No. 05-10-029-033 for the 2005 version [the 2005 version replaces the 2001 version]) prepared by Ecology for use by local governments that contains BMPs to prevent, control, or treat pollution in stormwater. Stormwater Management Program (SWMP) means a set of actions and activities designed to reduce the discharge of pollutants from the regulated small MS4 to the maximum extent practicable and to protect water quality, and comprising the components listed in S5 of S6 of the Western Washington Phase II Municipal Stormwater Permit and any additional actions necessary to meet the requirements of applicable requirements. Structural source control BMPs are physical, structural, or mechanical devices or facilities that are intended to prevent pollutants from entering stormwater. Structural source control BMPs typically include the following practices:  enclosing and/or covering the pollutant source (building or other enclosure, a roof over storage and working areas, temporary tarp, etc.).  segregating the pollutant source to prevent run-on of stormwater, and to direct only contaminated stormwater to appropriate treatment BMPs. ---PAGE BREAK--- List of Definitions Stormwater Pollution Prevention Plan viii F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Public Works FINAL.docm Treatment BMPs are intended to remove pollutants from stormwater. A few examples of treatment BMPs are wet ponds, oil/water separators (OWS), biofiltration swales, and constructed wetlands. Turbidity is a means by which to characterize stormwater. The dispersion or scattering of light in a liquid, caused by suspended solids and other factors, is commonly used as a measure of suspended solids in a liquid. Vehicle maintenance or storage facility means an uncovered area where any vehicles are regularly washed or maintained, or where at least 10 vehicles are stored. Water quality means the chemical, physical, and biological characteristics of water, usually with respect to its suitability for a particular purpose. Waters of the state include those waters as defined as “waters of the United States” in 40 CFR Subpart 122.2 within the geographic boundaries of Washington state and “waters of the state” as defined in Chapter 90.48 RCW, which include lakes, rivers, ponds, streams, inland waters, underground waters, salt waters, and all other surface waters and water courses within the jurisdiction of the state of Washington. ---PAGE BREAK--- 1: Introduction Stormwater Pollution Prevention Plan 1-1 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Public Works FINAL.docm STORMWATER POLLUTION PREVENTION PLAN 1. INTRODUCTION This section provides the background information for this Stormwater Pollution Prevention Plan including applicable permit requirements and the intended goals and objectives. This section also provides the limitations of this document. 1.1 Background This applies to the city of Puyallup’s (City) Public Works maintenance facility (Facility) located at 1100 39th Avenue SE, Puyallup, Washington (see Figure 2-1), also known as Corporate Yards. This identifies actions that Facility staff will take to comply with the terms and conditions of the Department of Ecology (Ecology)’s Western Washington Phase II Municipal Stormwater Permit (Phase II Permit). This was prepared in accordance with Phase II Permit condition S5.C.5.i, which requires the following activities:  implement nonstructural best management practices (BMPs) immediately after the is developed or updated  include a schedule for implementation of structural BMPs  inspect the effectiveness of BMPs periodically  conduct periodic visual inspection of discharges from the facility during wet and dry conditions  update the when major BMP and/or administrative role revisions occur. 1.2 Goals and Objectives This is intended to help the City satisfy the following goals:  implement and maintain BMPs that identify, reduce, eliminate, and/or prevent the discharge of stormwater pollutants  prevent violations of surface water quality, groundwater quality, or sediment management standards  eliminate the discharges of unpermitted process wastewater, domestic wastewater, non-contact cooling water, and other illicit discharges to stormwater drainage systems. To meet these goals, this takes the following actions:  identifies potential sources of stormwater pollution that could affect the quality of stormwater discharges associated with the Facility  evaluates the potential for stormwater contamination from the identified potential sources  identifies the stormwater BMPs that will be used at the Facility for the prevention and control of pollutants in stormwater discharges  identifies operations, maintenance, inspections, and record-keeping needed for these BMPs. The City has formed a Pollution Prevention (P2) team to oversee implementation of this The P2 team will annually review the and confirm its implementation. The P2 team is discussed in detail in Section 3.2. The P2 team will modify the annually or more often if needed to reflect changing conditions at the Facility, such as new operations, Facility modifications, or BMPs. Appendix A contains the Revision Form, which will be completed when revisions are made. ---PAGE BREAK--- 1: Introduction Stormwater Pollution Prevention Plan 1-2 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Public Works FINAL.docm 1.3 Limitations Ecology has not yet developed a template or guidelines specifically for municipal facilities covered by the Phase II Permit. Therefore, this was modeled after the city of Mount Vernon’s Fir Street Maintenance Facility (Brown and Caldwell 2009), which Ecology has cited as an example on its Web page titled Resource for Stormwater Management Plan Elements: Pollution Prevention and Good Housekeeping for Municipal Operations, which is located at the address below: (http://www.ecy.wa.gov/programs/wq/stormwater/municipal/pollutionPREVENTION.html).

FACILITY ASSESSMENT This section provides an overview of the Facility and its stormwater drainage system. 2.1 Overview of Facility and Operations The City’s Public Works Facility is located at 1100 39th Avenue SE in Puyallup, Washington, and encompasses a rectangular area of approximately 10 acres. Four main buildings and two storage sheds are located on the site. Approximately two-thirds of the site is covered with impervious surfaces. Figure 2-1 provides a vicinity map of the area. The Facility is owned by the city of Puyallup and is bordered by a secured fence with two main entry points. Buildings on site include:  Public Works administrative offices and storage building  Vehicle maintenance and truck wash building  Equipment shed  Information technology and emergency operations center  Two material storage sheds, and a  Fueling island 2.2 Facility Drainage Figure 2-2 shows the drainage features at the Facility. Runoff from the northwest portion of the Facility is collected in catch basins and a strip drain and conveyed to a storm sewer pipe and a ditch on the western edge of the site which lead to an EcoStorm Plus stormwater filtration system installed in 2011. Runoff from the fuel island passes through an oil/water separator (OWS) prior to discharge. Runoff from the northwest portion of the site discharges into the City storm sewer on 39th Avenue SE. Subsequently, the City storm sewer system appears to discharge to Bradley Lake, located approximately 0.5 miles northwest of the Site. Runoff from the southwestern portion of the Facility drains is collected in catch basins and conveyed via a storm sewer to a low area on the southwest corner of the site. Runoff from the eastern half of the Facility is collected in a series of grass-lined swales with check dams, which ultimately flow through a short section of pipe and then into a two-celled treatment pond located near the eastern edge of the site. The upper cell is a wet pond and the lower cell is a dry pond with check dams in it. The pond discharges into an unlined channel that flows to a wooded area at the southeast corner of the site. Runoff from the eastern portion appears to drain to a pothole nearby. ---PAGE BREAK--- 2: Facility Assessment Stormwater Pollution Prevention Plan 2-2 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Public Works FINAL.docm Figure 2-1.

BEST MANAGEMENT PRACTICES This section provides a description of best management practices (BMPs) that are recommended for the Facility. Stormwater BMPs include structures, activities, or practices intended to help prevent or reduce stormwater pollution. This section also discusses the Pollution Prevention (P2) team, training requirements, and the BMPs currently implemented at the site. 3.1 Facility BMPs Phase II Permit Section S5.i requires implementation of nonstructural and structural BMPs. To develop BMP recommendations for this we reviewed the Ecology (2005) stormwater manual as well as the city of Seattle and King County manuals to identify the potentially appropriate BMPs for each activity at the Facility. We identified the existing BMPs for each activity. We then developed the BMP recommendations presented in Table 3-1. The table lists the recommended BMPs for each activity and notes which BMPs are already being implemented. The BMPs are included as separate activity pullout sheets in Appendix B for ease of use in the field. Table 3-1 includes a combination of structural and nonstructural measures. The nonstructural measures include general good-housekeeping measures that apply throughout the Facility (sweeping, etc.), as well as measures tailored to a specific activity checking storage tanks for spills and leaks). The table also includes structural measures repair or replace spill containment pad around fuel island). In general, the structural measures focus on activities and areas where nonstructural measures are impractical. As noted in Table 3-1, the Facility has a number of stormwater treatment BMPs in place, including the following:  storm filter vault that treats runoff from the northwest portion of the site  a coalescing plate OWS that treats runoff from the fuel island  grass-lined swales with check dams to remove sediment in runoff from the outdoor storage areas  a two-celled pond (wet cell and dry cell) to remove sediment and other pollutants in runoff from the eastern portion of the Facility. Both cells of the pond should be visually inspected for any potential water quality issues, as described in Section 4. The Facility also contains an OWS and settling vault that are connected to the sanitary sewer system. These devices are intended to remove settleable solids and other pollutants that could cause maintenance problems in the sanitary system. The Phase II Permit prohibits most non-stormwater discharges. Therefore, Table 3-1 also includes recommended measures to address the following three non-stormwater discharges that were identified on the site:  The administration building contains a water meter testing device that discharges potable water into the storm drain adjacent to the building. Because chlorine can be toxic to aquatic life, the Phase II Permit requires that potable water must be de-chlorinated before it is discharged to the storm drain. The City could address this discharge by re-routing the flow to the sanitary sewer, de-chlorinating the water prior to discharge into the storm drain, or directing the runoff from the device to nearby grassy/lawn areas. Several manufacturers have developed portable de-chlorination devices for use during fire flow testing, water line flushing, and similar activities. Installing such a device at the outlet to the water meter test pipe would meet the Phase II Permit requirement if re-routing to the sanitary sewer or directing it to a grassy/lawn area are not viable options.  The facility contains an outdoor, covered fueling station with two gas pumps. Currently, the facility needs the canopy replaced, the fuel island needs repair to provide spill containment and divert run-on, and ---PAGE BREAK--- 3: Best Management Practices (BMPs) Stormwater Pollution Prevention Plan 3-2 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Public Works FINAL.docm the storm inlet needs to be relocated so runoff from the containment pad is directed to the OWS. The following items also need to be addressed: o Post signs to remind employees not to top off the fuel tank when filling. o Route fuel island runoff to sanitary sewer  There is an outdoor, uncovered area on the site used for storing common materials used in the maintenance and repair of the City’s infrastructure (roads, MS4, etc.). It is a graveled area and the materials stored, such as gravel, sands, etc. contain sediment-laden material that should not be allowed to enter the storm system. One option to prevent the runoff of sediment laden runoff into any nearby catch basins is to install a cutoff (French) drain that will catch any sediment laden runoff and direct it to a device that will allow for the removal of the sediment, such as a storm filter vault or the onsite settlement pond. ---PAGE BREAK--- 3: Best Management Practices Stormwater Pollution Prevention Plan F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Public Works FINAL.docm Table 3-1.

Training material content will include the information in this spill response procedures, and visual inspection procedures. ---PAGE BREAK--- 4: Monitoring (Visual Inspections) Stormwater Pollution Prevention Plan 4-1 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Public Works FINAL.docm STORMWATER POLLUTION PREVENTION PLAN 4. MONITORING (VISUAL INSPECTIONS) The Phase II Permit requires that the prescribe periodic visual observation of discharges from the Facility to evaluate the effectiveness of BMPs (S5.C.5.i.). The stormwater BMP monitoring for the Facility will rely upon annual wet and dry weather visual inspections of discharge quality to indicate obvious or potential problems and an annual BMP evaluation. The wet weather inspection will help assess overall BMP performance. The dry weather inspection will help confirm that illicit discharges have been eliminated. Coupled with the other BMPs for the Facility, as discussed in Section 3, this approach should reduce the potential for adverse impacts on stormwater quality. 4.1 Drainage and Outfall Characteristics The locations recommended for the wet and dry weather visual inspections are MON-1 and MON-2. These locations are shown in Figure 2-2 and described below. MON-1 is located at the catch basin at the northwestern corner of the site, where the facility storm drain system connects to a storm sewer under 39th Avenue SE. It receives runoff from the northwestern portion of the site, including the vehicle rinsing area, fuel island, public works outdoor material storage area, dumpster, decant facility, backup generator, and propane tank. MON-2 is located at the outlet pipe for the cell of the stormwater pond located at the eastern edge of the site. This pond treats stormwater from the western portion of the site, which encompasses a range of materials storage areas and a dumpster used for the street sweeper waste. 4.2 Wet and Dry Weather Visual Inspections Each outfall will be inspected twice each year, once during dry weather and once during a storm runoff event. Appendix C contains the inspection forms. A designated member of the P2 team will perform these inspections. Wet weather inspections means that discharges from the identified outfalls will be assessed during a significant rainfall event resulting in visible stormwater runoff and discharges from the site. Inspections are not required to be conducted outside of regular business hours or during unsafe conditions. Dry weather inspections should be conducted when no rain has occurred at the Facility for at least 24 hours prior to inspection. The person conducting the inspection should look for the indicators described below:  Floatables: Floatables indicate if obvious trash or other controllable debris, such as landscaping material, leaf litter, etc. has entered into the storm system.  Foam: Foam indicates that potentially soap or other cleaning products have entered into the storm system. However, stormwater can often be foamy from pollen and other natural organic material. One can determine the difference by inspecting appearance and smell. If the foam is persistent and accompanied by a fragrant odor, it could be related to a cleaning product. If the suds break up quickly, then it could be from turbulence and/or natural conditions.  Sheen: Sheen, which also looks like a rainbow hue on the water surface, is commonly indicative of petroleum products, often present from parking lot runoff. If gasoline or a flammable solvent is suspected, the inspector should leave the immediate area, notify facility management immediately, and take action to prevent a fire or explosion.  Turbidity: Turbidity, which makes the water appear cloudy, is usually an indication of dirt or sediment in the water. ---PAGE BREAK--- 4: Monitoring (Visual Inspections) Stormwater Pollution Prevention Plan F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Public Works FINAL.docm  Odor: Certain contaminants in stormwater can give off specific odors, which should be described as accurately as possible. Odors can include those similar to rotten eggs, solvent, fuel/oil, cleaning agent, etc. When noting odors, the inspector should make sure that the odor is not related to sources other than beyond the runoff being inspected. If gasoline or a flammable solvent is suspected, the inspector should leave the immediate area, notify the Facility management immediately, and take action to prevent a fire or explosion (see spill response procedures in Section 5 of this  Discoloration: A red/orange color can indicate rust from iron pipes or iron bacteria. Other colors such as white could indicate paint or cleaning agent emulsions.  Flow: Note presence or discharge from each outfall. If flow is present, the approximate discharge rate should be indicated on the inspection form < 10 gpm, or >10 gpm). The inspector should note whether each indicator was present or absent at the time of inspection, and note the approximate magnitude for any indicators that were observed. 4.3 Annual BMP Evaluation Once each year, the P2 team will evaluate the BMPs at the Facility to determine if additional BMPs are needed or if current BMPs should be modified. The evaluations should be performed using the Annual BMP Evaluation Form. A copy of this form is provided in Appendix D. 4.4 Revisions The should be revisited once per year and revised if needed to reflect any administrative changes change in P2 team members). In addition, the should be revised when significant changes occur that could affect stormwater quality and BMP needs. Appendix A contains a copy of the Revision Form. ---PAGE BREAK--- 5: Spill Response Stormwater Pollution Prevention Plan 5-1 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Public Works FINAL.docm STORMWATER POLLUTION PREVENTION PLAN 5. SPILL RESPONSE 5.1 Spill Response Plan and Emergency Cleanup This section describes the Facility’s Spill Response Plan (SRP). The main objective of responding to pollutant spill events is to contain the spill in order to minimize detrimental impacts to the environment and life safety. This SRP is intended for the use by the city of Puyallup’s public works staff. In response to a spill, staff should take the following steps: 1. Call supervisor Donald Keith Henry at (253) 841-5560. Alternative contacts are: TedEgeland, (253) 841-5469, John Wiklander, (253) 770-3341, and Karen Michaud, (253) 841-5593. 2. If an employee can identify the material, an employee may conduct spill containment and/or cleanup only if ALL of the following conditions are met:  Without jeopardizing safety, the employee is able to determine that the material is not a hazardous material.  The employee considers himself or herself prepared and trained to respond to the spill.  Appropriate spill containing materials are available. 3. If the material involved shows ANY indication of being hazardous (for example, flammable, corrosive, or dangerous in nature), employees should take the following steps: ACTION: If you cannot identify the product involved, STOP and follow these procedures: 1. Leave the immediate area where the product is located. 2. Prevent others from approaching the product. 3. Call the police and Fire Department by dialing 911. If an employee cannot identify the material, or determines that the material is hazardous, the employee should follow Spill Response Plan included in Appendix E, along with the corresponding Spill Response flow diagram included in Appendix F. 5.2 Location of Spill Kits Spill kits containing adsorbent materials are located at the fuel island and in the mechanics/storage building. Spill kit materials are re-stocked after each use. ---PAGE BREAK--- 6: Record-keeping Stormwater Pollution Prevention Plan 6-1 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup Public Works FINAL.docm STORMWATER POLLUTION PREVENTION PLAN 6.

Definitions not provided from the Permit were taken from other sources, including the Washington Department of Ecology Stormwater Management Manual for Western Washington, EPA NPDES website glossary, and the Illicit Discharge Detection and Elimination, A Guidance Manual for Program Development and Technical Assessments. Best management practices (BMPs) are the schedules of activities, prohibitions of practices, maintenance procedures, and structural and/or managerial practices approved by the Department of Ecology (Ecology) that, when used singly or in combination, prevent or reduce the release of pollutants and other adverse impacts to waters of Washington State. Combined sewer means a sewer that has been designed to serve as a sanitary sewer and a storm sewer, and into which inflow is allowed by local ordinances. Discoloration is a means by which to characterize stormwater. Typically, stormwater is yellowish in color. However, discoloration other than turbidity can indicate whether there is rust from iron pipes or iron bacteria, as seen by a yellowish/red color, or if paint or cleaning agent emulsions have entered the stormwater system, as indicated by a white cloudy color. Erosion and sediment control BMPs are BMPs that are intended to prevent erosion and sedimentation, such as preserving natural vegetation, seeding, mulching and matting, plastic covering, and sediment traps and ponds. Erosion sediment control BMPs are synonymous with stabilization and structural BMPs. Floatables is a means by which to characterize stormwater. A floatable is used as an indicator if very obvious trash or other controllable debris, such as landscaping material, leaf litter, etc. has entered into the storm system. Foam is a means by which to characterize stormwater. Foam is used as an indicator that potentially soap or other cleaning products have entered into the storm system. However, stormwater can often be foamy from pollen and other natural organic material. The way to tell the difference is by touch and smell. If the foam is persistent and accompanied by a fragrant odor, it is probably coming from a cleaning product. If the suds break up quickly, then it is probably from turbulence and/or natural conditions. Hazardous substance: Any material that poses a threat to human health and/or the environment. Typical hazardous substances are toxic, corrosive, ignitable, explosive, or chemically reactive. Any substance designated by the U.S. Environmental Protection Agency (EPA) to be reported if a designated quantity of the substance is spilled in the waters of the United States or is otherwise released into the environment. Hyperchlorinated means water that contains more than 10 mg/L chlorine. Disinfection of water mains and appurtenances requires a chlorine residual of 10 mg/L at the end of the disinfection period. This level is well above the Maximum Residual Disinfectant Level of an annual average of 4 mg/L chlorine for potable water. Illegal dumping means any intentional and non-permitted disposal of any substance other than stormwater into the municipal separate storm sewer system, unless otherwise called out as an allowed non-stormwater discharge. Illicit connection means any manmade conveyance that is connected to a municipal separate storm sewer without a permit, excluding roof drains and other similar type connections. Examples include sanitary sewer ---PAGE BREAK--- List of Definitions Stormwater Pollution Prevention Plan vi F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup WWTP FINAL.doc connections, floor drains, channels, pipelines, conduits, inlets, or outlets that are connected directly to the municipal separate storm sewer system. Illicit discharge means any discharge to the municipal separate storm sewer that is not composed entirely of stormwater except discharges pursuant to a National Pollutant Discharge Elimination System (NPDES) permit (other than the NPDES permit for discharges from the municipal separate storm sewer) and discharges resulting from fire fighting activities. Industrial Stormwater General Permit (ISGP) means the NPDES Industrial Stormwater General Permit, issued by Ecology for stormwater discharges associated with industrial activities (issued 2002, modified 2004, effective January 2005). Material storage facilities are uncovered areas where bulk materials (liquid, solid, granular, etc.) are stored in piles, barrels, tanks, bins, crates, or by other means. Municipal Separate Storm Sewer System (MS4) means a conveyance, or system of conveyances (including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, manmade channels, or storm drains) that meets the following criteria: i. Owned or operated by a state, city, town, borough, county, parish, district, association, or other public body (created by or pursuant to state law) having jurisdiction over disposal of wastes, stormwater, or other wastes, including special districts under state law such as a sewer district, flood control district or drainage district, or similar entity, or an Indian tribe or an authorized Indian tribal organization, or a designated and approved management agency under Section 208 of the federal Clean Water Act (CWA) that discharges to waters of the United States. ii. Designed or used for collecting or conveying stormwater. iii. Is not a combined sewer. iv. Is not part of a Publicly Owned Treatment Works (POTW) as defined at 40 CFR 122.2. National Pollutant Discharge Elimination System (NPDES) means the national program for issuing, modifying, revoking, and reissuing, terminating, monitoring, and enforcing permits, and imposing and enforcing pretreatment requirements, under Sections 307, 402, 318, and 405 of the federal Clean Water Act, for the discharge of pollutants to surface waters of the state from point sources. These permits are referred to as NPDES permits and, in Washington State, are administered by Ecology. Non-stormwater discharges are discharges of process wastewaters, vehicle wash waters, cooling waters, or any other wastewaters associated with the facility into the stormwater collection system. Other discharges must be addressed in a separate NPDES permit (EPA). See also Illicit discharges. Certain non-stormwater discharges are conditionally approved under the ISGP but are subject to specific provisions, including identifying the location, flow volumes, quality, potential for water quality issues, and ability to apply appropriate BMPs. Examples of conditionally approved non-stormwater discharges under an ISGP include the following:  discharges from firefighting activities  fire protection system flushing, testing, and maintenance  discharges of potable water including water line flushing, provided that water line flushing must be de-chlorinated prior to discharge  uncontaminated air conditioning or compressor condensate  irrigation drainage  uncontaminated groundwater or spring water ---PAGE BREAK--- List of Definitions Stormwater Pollution Prevention Plan vii F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup WWTP FINAL.doc  discharges associated with dewatering of foundations, footing drains, or utility vaults where flows are not contaminated with process materials such as solvents. Incidental windblown mist from cooling towers that collects on rooftops or areas adjacent to the cooling tower. This does not include intentional discharges from cooling towers such as piped cooling tower blow down or drains. Odor is a means by which to characterize stormwater. Contaminants in stormwater can give off specific odors, which should be described as accurately as possible. Odors can include rotten eggs, solvent, fuel/oil, cleaning agent, etc. When noting odors, make sure the odor is not related to other sources beyond the runoff being inspected. If gasoline or a flammable solvent is suspected, leave the immediate area, notify facility management immediately, and take action to prevent a fire or explosion. Operational source control BMPs are schedules of activities, prohibition of practices, and other managerial practices to prevent or reduce pollutants from entering stormwater. Operational BMPs include formation of a pollution prevention team, good housekeeping, preventive maintenance procedures, spill prevention and cleanup, employee training, inspections of pollutant sources and BMPs, and record-keeping. They can also include process changes, raw material/product changes, and recycling wastes. Outfall means a point source as defined by 40 CFR 122.2 at the point where a municipal separate storm sewer discharges to waters of the state and does not include open conveyances connecting two municipal separate storm sewer systems, or pipes, tunnels, or other conveyances which connect segments of the same stream or other waters of the state and are used to convey waters of the state. Runoff is water that travels across the land surface and discharges to water bodies either directly or through a collection and conveyance system (see also Stormwater). Run-on is stormwater runoff from another entity/jurisdiction or another area of the property that is not subject to the provision at issue. Sediment/erosion-sensitive feature means an area subject to significant degradation due to the effect of construction runoff or areas requiring special protection to prevent erosion. Sheen is used as an indicator in stormwater flows of petroleum products. Sheen looks like a rainbow hue on the water surface, and is commonly indicative of petroleum products, often present from parking lot runoff. Significant material includes, but is not limited to, raw materials; fuels; materials such as solvents, detergents, and plastic pellets; finished materials such as metallic products; raw materials used in food processing or production; hazardous substances designated under Section 101 (14) of CERCLA; any chemical the facility is required to report pursuant to Section 313 of Title III of SARA; fertilizers; pesticides; and waste products such as ashes, slag, and sludge that have the potential to be released with stormwater discharges. Source control BMPs means a structure or operation that is intended to prevent pollutants from coming into contact with stormwater through physical separation of areas or careful management of activities that are sources of pollutants. The Western Washington Stormwater Management Manual separates source control BMPs into two types. Structural source control BMPs are physical, structural, or mechanical devices or facilities that are intended to prevent pollutants from entering stormwater. Operational BMPs are nonstructural practices that prevent or reduce pollutants from entering stormwater. Spill means a release, either accidental or intentional, of a non-stormwater material. Stormwater means runoff during and following precipitation and snowmelt events, including surface runoff and drainage. ---PAGE BREAK--- List of Definitions Stormwater Pollution Prevention Plan viii F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup WWTP FINAL.doc Stormwater Management Manual for Western Washington means the five-volume technical manual (Publications Nos. 99-11 through 99-15 for the 2001 version and Publication No. 05-10-029-033 for the 2005 version [the 2005 version replaces the 2001 version]) prepared by Ecology for use by local governments that contains BMPs to prevent, control, or treat pollution in stormwater. Stormwater Management Program (SWMP) means a set of actions and activities designed to reduce the discharge of pollutants from the regulated small MS4 to the maximum extent practicable and to protect water quality, and comprising the components listed in S5 of S6 of the Western Washington Phase II Municipal Stormwater Permit and any additional actions necessary to meet the requirements of applicable requirements. Structural source control BMPs are physical, structural, or mechanical devices or facilities that are intended to prevent pollutants from entering stormwater. Structural source control BMPs typically include the following practices:  enclosing and/or covering the pollutant source (building or other enclosure, a roof over storage and working areas, temporary tarp, etc.).  segregating the pollutant source to prevent run-on of stormwater, and to direct only contaminated stormwater to appropriate treatment BMPs. Treatment BMPs are intended to remove pollutants from stormwater. A few examples of treatment BMPs are wet ponds, oil/water separators (OWS), biofiltration swales, and constructed wetlands. Turbidity is a means by which to characterize stormwater. The dispersion or scattering of light in a liquid, caused by suspended solids and other factors, is commonly used as a measure of suspended solids in a liquid. Vehicle maintenance or storage facility means an uncovered area where any vehicles are regularly washed or maintained, or where at least 10 vehicles are stored. Water quality means the chemical, physical, and biological characteristics of water, usually with respect to its suitability for a particular purpose. Waters of the state include those waters as defined as “waters of the United States” in 40 CFR Subpart 122.2 within the geographic boundaries of Washington state and “waters of the state” as defined in Chapter 90.48 RCW, which include lakes, rivers, ponds, streams, inland waters, underground waters, salt waters, and all other surface waters and water courses within the jurisdiction of the state of Washington. . ---PAGE BREAK--- 1: Introduction Stormwater Pollution Prevention Plan 1-1 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup WWTP FINAL.doc STORMWATER POLLUTION PREVENTION PLAN 1. INTRODUCTION This section provides the background information for this Stormwater Pollution Prevention Plan including applicable permit requirements and the intended goals and objectives. This section also provides the limitations of this document. 1.1 Background This applies to the city of Puyallup’s (City) Wastewater Treatment Plant (WWTP) Site located at 1602 18th St NW, Puyallup, Washington (see Figure 2-1). This identifies actions that WWTP staff will take to comply with the terms and conditions of the Department of Ecology (Ecology)’s Western Washington Phase II Municipal Stormwater Permit (Phase II Permit). This was prepared in accordance with Phase II Permit condition S5.C.5.i, which requires the following activities:  implement nonstructural best management practices (BMPs) immediately after the is developed or updated  include a schedule for implementation of structural BMPs  inspect the effectiveness of BMPs periodically  conduct periodic visual inspection of discharges from the facility during wet and dry conditions  update the when major BMP and/or administrative role revisions occur. 1.2 Goals and Objectives This is intended to help the City satisfy the following goals:  implement and maintain BMPs that identify, reduce, eliminate, and/or prevent the discharge of stormwater pollutants  prevent violations of surface water quality, groundwater quality, or sediment management standards  eliminate the discharges of unpermitted process wastewater, domestic wastewater, non-contact cooling water, and other illicit discharges to stormwater drainage systems. To meet these goals, this takes the following actions:  identifies potential sources of stormwater pollution that could affect the quality of stormwater discharges associated with the WWTP Site  evaluates the potential for stormwater contamination from the identified potential sources  identifies the stormwater BMPs that will be used at the WWTP Site for the prevention and control of pollutants in stormwater discharges  identifies operations, maintenance, inspections, and record-keeping needed for these BMPs. The City has formed a Pollution Prevention (P2) team to oversee implementation of this The P2 team will annually review the and confirm its implementation. The P2 team is discussed in detail in ---PAGE BREAK--- 1: Introduction Stormwater Pollution Prevention Plan 1-2 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup WWTP FINAL.doc Section 3.2. The P2 team will modify the annually or more often if needed to reflect changing conditions at the WWTP Site, such as new operations, WWTP Site modifications, or BMPs. Appendix A contains the Revision Form, which will be completed when revisions are made. 1.3 Limitations Ecology has not yet developed a template or guidelines specifically for municipal facilities covered by the Phase II Permit. Therefore, this was modeled after the city of Mount Vernon’s Fir Street Maintenance Facility (Brown and Caldwell 2009), which Ecology has cited as an example on its Web page titled Resource for Stormwater Management Plan Elements: Pollution Prevention and Good Housekeeping for Municipal Operations, which is located at the address below: (http://www.ecy.wa.gov/programs/wq/stormwater/municipal/pollutionPREVENTION.html). This is organized to be easy to use and update. The main body contains useful information for those in charge of administering and documenting implementation of the plan. The appendices contain the most relevant information for City staff at the WWTP Site. ---PAGE BREAK--- 2: Facility Assessment Stormwater Pollution Prevention Plan 2-3 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup WWTP FINAL.doc STORMWATER POLLUTION PREVENTION PLAN 2. FACILITY ASSESSMENT This section provides an overview of the Facility and its stormwater drainage system. 2.1 Overview of Facility and Operations The City’s WWTP Site is located at 1602 18th St NW in Puyallup, Washington, and encompasses a rectangular area of approximately 11.5 acres. Several buildings are located on the site, as well as structures that are part of the wastewater treatment process. Approximately one third of the site is covered with impervious surfaces. Figure 2-1 provides a vicinity map of the area. The WWTP Site is owned by the City and is bordered by a secured fence with two main entry points. Multi- purpose buildings on site include:  Administration Building  Vehicle Storage Garage  Equipment Maintenance Building  Operations Building  Dry Storage Building Process related Structures and Buildings also on the WWTP Site are:  Anaerobic Digesters  Headworks  Blower Building  Digester Building  Effluent Pump Station  Solids Handling Facility  Secondary Clarifiers  Primary Clarifiers  Biofilter  Scum Removal Facilities  RAS/WAS Pump Station  Aeration Basins 2.2 Facility Drainage Figure 2-2 shows the drainage features at the WWTP Site. Runoff from the eastern portion of the WWTP Site is collected in catch basins and is subsequently discharged to the Puyallup River, located on the other side of River Road from the WWTP Site. Runoff from the western portion of the WWTP Site is collected in catch basins and routed to the Stormwater Pumping Station (SPS). The area that drains to the sanitary sewer system through the SPS is designated on Figure 2-2 with a blue dotted line. During all but the largest storms, ---PAGE BREAK--- 2: Facility Assessment Stormwater Pollution Prevention Plan 2-4 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup WWTP FINAL.doc the SPS routes stormwater to the headworks of the WWTP, so that the stormwater is treated before discharge into the Puyallup River. After the first two hours of exceptionally large storms, the SPS may be used to pump stormwater directly to the Puyallup River (rather than through the headworks of the WWTP). ---PAGE BREAK--- 2: Facility Assessment Stormwater Pollution Prevention Plan 2-5 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup WWTP FINAL.doc Figure 2-1.

BEST MANAGEMENT PRACTICES This section describes the best management practices (BMPs) recommended for the WWTP Site. Stormwater BMPs include structures, activities, or practices intended to help prevent or reduce stormwater pollution. This section also discusses the Pollution Prevention (P2) team, training requirements, and the BMPs currently implemented at the site. 3.1 Facility BMPs Phase II Permit Section S5.i requires implementation of appropriate BMPs. To develop BMP recommendations for this we reviewed the Ecology (2005) stormwater manual as well as the city of Seattle and King County manuals to identify the potentially appropriate BMPs for each activity at the WWTP Site. We identified the existing BMPs for each activity and then developed the BMP recommendations presented in Table 3-1. The table lists the recommended BMPs for each activity and notes which BMPs are already being implemented. The BMPs are included as separate activity pullout sheets in Appendix B for ease of use in the field. Nearly all of the BMPS listed in Table 3-1 are nonstructural measures. These include general good- housekeeping measures that apply throughout the WWTP Site (sweeping, etc.), as well as measures tailored to a specific activity checking storage tanks for spills and leaks). The only recommended “structural” measure involves posting signs at the fueling area. Drainage from the areas on the western portion of the WWTP Site is routed to sanitary sewer, except during heavy rainfall when it is pumped using the Stormwater Pump Station to the Puyallup River. In the case of heavy rainfall, the Stormwater Pump Station is turned on after approximately 2 hours of rainfall, to minimize potential pollutants in the stormwater. Although several activities take place on the western portion of the WWTP Site, which drains to sanitary sewer the majority of the time, BMPs are recommended to keep pollutants out of the system. The Phase II Permit prohibits most non-stormwater discharges. No non-stormwater discharges were identified on the Site.. ---PAGE BREAK--- 3: Best Management Practices Stormwater Pollution Prevention Plan F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup WWTP FINAL.doc Table 3-1.

Employee training is an ongoing program, and will be provided for all existing employees on an annual basis and for all new employees when they begin work at the WWTP. Training material content will include the information in this spill response procedures, and visual inspection procedures. ---PAGE BREAK--- 4: Monitoring (Visual Inspections) Stormwater Pollution Prevention Plan 4-1 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup WWTP FINAL.doc STORMWATER POLLUTION PREVENTION PLAN 4. MONITORING (VISUAL INSPECTIONS) The Phase II Permit requires that the prescribe periodic visual observation of discharges from the WWTP Site to evaluate the effectiveness of BMPs (S5.C.5.i.). The stormwater BMP monitoring for the WWTP Site will rely upon annual wet and dry weather visual inspections of discharge quality to indicate obvious or potential problems and an annual BMP evaluation. The wet weather inspection will help assess overall BMP performance. The dry weather inspection will help confirm that illicit discharges have been eliminated. Coupled with the other BMPs for the WWTP Site, as discussed in Section 3, this approach should reduce the potential for adverse impacts on stormwater quality. 4.1 Drainage and Outfall Characteristics The locations recommended for the wet and dry weather visual inspections are MON-1 and MON-2. These locations are shown on Figure 2-2 and described below. • MON-1 is located at the catch basin at the northern edge of the site, closest to the north access gate. It receives runoff from the northern portion of the site. • MON-2 is located at the catch basin at the northeast corner of the site. It receives runoff from the eastern portion of the site, including fuel tanks for back-up generators and copper removal chemical transfer area. 4.2 Wet and Dry Weather Visual Inspections Each outfall will be inspected twice each year, once during dry weather and once during a storm runoff event. Appendix C contains the inspection forms. A designated member of the P2 team will perform these inspections. Wet weather inspections means that discharges from the identified outfalls will be assessed during a significant rainfall event resulting in visible stormwater runoff and discharges from the site. Inspections are not required to be conducted outside of regular business hours or during unsafe conditions. Dry weather inspections should be conducted when no rain has occurred at the Facility for at least 24 hours prior to inspection. The person conducting the inspection should look for the indicators described below:  Floatables: Floatables indicate if obvious trash or other controllable debris, such as landscaping material, leaf litter, etc. has entered into the storm system.  Foam: Foam indicates that potentially soap or other cleaning products have entered into the storm system. However, stormwater can often be foamy from pollen and other natural organic material. One can determine the difference by inspecting appearance and smell. If the foam is persistent and accompanied by a fragrant odor, it could be related to a cleaning product. If the suds break up quickly, then it could be from turbulence and/or natural conditions. ---PAGE BREAK--- 4: Monitoring (Visual Inspections) Stormwater Pollution Prevention Plan F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup WWTP FINAL.doc  Sheen: Sheen, which also looks like a rainbow hue on the water surface, is commonly indicative of petroleum products, often present from parking lot runoff. If gasoline or a flammable solvent is suspected, the inspector should leave the immediate area, notify facility management immediately, and take action to prevent a fire or explosion.  Turbidity: Turbidity, which makes the water appear cloudy, is usually an indication of dirt or sediment in the water.  Odor: Certain contaminants in stormwater can give off specific odors, which should be described as accurately as possible. Odors can include those similar to rotten eggs, solvent, fuel/oil, cleaning agent, etc. When noting odors, the inspector should make sure that the odor is not related to sources other than beyond the runoff being inspected. If gasoline or a flammable solvent is suspected, the inspector should leave the immediate area, notify the Facility management immediately, and take action to prevent a fire or explosion (see spill response procedures in Section 5 of this  Discoloration: A red/orange color can indicate rust from iron pipes or iron bacteria. Other colors such as white could indicate paint or cleaning agent emulsions.  Flow: Note presence or discharge from each outfall. If flow is present, the approximate discharge rate should be indicated on the inspection form < 10 gpm, or >10 gpm). The inspector should note whether each indicator was present or absent at the time of inspection, and note the approximate magnitude for any indicators that were observed. 4.3 Annual BMP Evaluation Once each year, the P2 team will evaluate the BMPs at the WWTP Site to determine if additional BMPs are needed or if current BMPs should be modified. The evaluation s should be performed using the Annual BMP Evaluation Form. A copy of this form is provided in Appendix D. 4.4 Revisions The should be revisited once per year and revised if needed to reflect any administrative changes change in P2 team members). In addition, the should be revised when significant changes occur that could affect stormwater quality and BMP needs. Appendix A contains a copy of the Revision Form. ---PAGE BREAK--- 5: Spill Response Stormwater Pollution Prevention Plan 5-1 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup WWTP FINAL.doc STORMWATER POLLUTION PREVENTION PLAN 5. SPILL RESPONSE 5.1 Spill Response Plan and Emergency Cleanup This section describes the WWTP Site’s Spill Response Plan (SRP). The main objective of responding to pollutant spill events is to contain the spill in order to minimize detrimental impacts to the environment and life safety. This SRP is intended for the use by the city of Puyallup’s WWTP staff. In response to a spill, staff should take the following steps: 1. Call Manager Don Lange [PHONE REDACTED] or Supervisor James Lee [PHONE REDACTED] 2. If an employee can identify the material, an employee may conduct spill containment and/or cleanup only if ALL of the following conditions are met:  Without jeopardizing safety, the employee is able to determine that the material is not a hazardous material.  The employee considers himself or herself prepared and trained to respond to the spill.  Appropriate spill containing materials are available. 3. If the material involved shows ANY indication of being hazardous (for example, flammable, corrosive, or dangerous in nature), employees should take the following steps: ACTION: If you cannot identify the product involved, STOP and follow these procedures: 1. Leave the immediate area where the product is located. 2. Prevent others from approaching the product. 3. Call the Police and Fire Department by dialing 911. If an employee cannot identify the material, or determines that the material is hazardous, the employee should follow Spill Response Plan included in this section, along with the corresponding Spill Response flow diagram included in Appendix F. 5.2 Location of Spill Kits Spill kits containing adsorbent materials are located in the Solids handling Facility, Blower Building, Headworks Building, and maintenance buildings. ---PAGE BREAK--- 6: Record-keeping Stormwater Pollution Prevention Plan 6-1 F:\Yards\Storm Water\NPDES Road Revisions\2012 Puyallup WWTP FINAL.doc STORMWATER POLLUTION PREVENTION PLAN 6.

With that adoption, the ordinance and subsequent Puyallup Municipal Code (PMC) section 21.10.210 Low Impact Development encourages the employment of LID practices under the guidelines in Appendix C of Volume III of the 2005 Manual. Based on this adoption, all LID Best Management Practices included in Appendix C can be utilized on new development and redevelopment projects within the City. The measures included are: • Permeable Pavements • Dispersion • Vegetated Roofs • Rainwater Harvesting • Reverse Slope Sidewalks • Minimal Excavation Foundations • Bioretention (Rain Gardens) One measure, which I consider LID, but is not specifically listed in Appendix C is soil amendment (soil quality). This required measure reduces surface water runoff as compared to a “classic” subdivision where soil would be stripped, the remaining inorganic soil compacted and overlain with a thin layer of soil and sod. Soil amendment, as described in BMP T5.13 Post Construction Soil Quality and Depth, is probably one of the most overlooked, least enforced requirements of the 2005 Manual. This is unfortunate, because as the BMP T5.13’s flow control credits section alludes, there is significant surface water runoff reduction achieved by proper implementation of this BMP. Since BMP T5.13 is required under Minimum Requirement and most any site triggering the thresholds of the 2005 Manual will also trigger Minimum Requirement this should be a widely used BMP, yet I have seen very little evidence of it in the field, in the City of Puyallup or other jurisdictions. For the City, we have utilized the 1 acre exemption allowed under the Phase II permit, which, when coupled with vesting of some proposed projects, has resulted in no projects actually falling under the requirements of 2005 Manual for this reporting period. BMP T5.13’s requirements are not onerous; it only requires an 8” depth of organic compost amended soils, with an additional 4” of scarified mixing zone. This improved soil condition will not only provide significant stormwater benefits but will produce healthier plant growth, which requires less water, fertilizer, and pesticide. The developer ---PAGE BREAK--- Low Impact Development (LID): Current Practice and Barriers to Implementation March 31, 2011 incentive, for those who want to avoid the cost of implementing this BMP, is an LID measure, not disturbing the vegetation and soil in the first place. Practices Available for this permit term: The City of Puyallup has an ongoing rain garden installation program, utilizing Ecology grant funds, to educate citizens about the advantages of rain garden installation. We are planning to continue this program for the short term in its current state, but hope to move to a more cost shared, incentive type program for rain garden installations. The ideal state would be to have citizens installing rain gardens on their own, knowing that every one they install does a little bit to help improve surface water quality. The City of Puyallup has also incorporated porous pavers into our most recent neighborhood rain garden installation on 18th St SW. The City has been encouraging private development applicants to utilize LID where possible. The Benaroya Business Park project has installed pervious concrete parking lots, and Sound Transit has utilized rain gardens at their Red Lot project for water quality treatment (but not flow control). Puyallup’s City Hall incorporates demonstration green roofs, with educational water level LEDs showing the relative depths of standard roof, 2” depth green roof and 4” depth green roof. Additionally, the roof runoff is directed to a cistern and reused for irrigation. The site also incorporates rain gardens along Meridian. While I can think of no examples of dispersion, reverse slope sidewalks and minimal excavation foundations, I believe there is no reason those measures couldn’t have been utilized in Puyallup somewhere. Planned Actions: The City of Puyallup has a number of projects planned for the 5th year of the permit. While this report requires actions that prevent stormwater impacts, I believe it is important to note actions that are intended to mitigate stormwater impacts or improve water quality through restoration efforts as well. A quick summary of planned projects is given below: Neighborhood Rain Garden Program: The City is planning on three more neighborhood rain garden installations, which will total between 18-24 rain gardens. We are focusing on the Clarks Creek basin because of the water quality concerns within this basin. The first installation will occur in the 6th St SW Neighborhood on May 21. In addition to the 6-8 rain gardens, we hope to install at least one porous pavement driveway. As we have continued to develop and improve this program, these events have become mini-environmental fairs. We have had the Puyallup River Watershed Council, WSU Puyallup, and the Pierce County-City of Tacoma Health Department participate with booths providing more information on water quality issues and other environmentally friendly practices. We started incorporating fish friendly car wash demonstrations, utilizing our car wash kits at our 5th St SE event and ---PAGE BREAK--- Low Impact Development (LID): Current Practice and Barriers to Implementation March 31, 2011 have since continued this effort with subsequent events. At the last event, we included a free home energy audit, under a grant program that was being implemented at the time. If we can work out the details, we would like to include a rain water harvesting element for this year’s event as well. For this year’s events, we are answering a perceived need to have more designers and contractors become familiar and comfortable with rain gardens, so that we can build the base. We are selecting a landscape architecture firm to work with the residents in designing their rain gardens, and also to oversee the contractor. With the contractor being the larger need of the two, we are hoping to obtain one or two contractors who are willing to learn on the job about rain gardens. Our second and third events are scheduled in July and September. Our September event will likely have Ciscoe Morris broadcasting live from the site. There is a chance that EPA Region 10 may choose to have a media event at the May 21 installation event. Clarks Creek Riparian Habitat and Porous Maintenance Road: The project proposes relocating an existing maintenance road/pedestrian path which is immediately adjacent to Clarks Creek, within City owned Clarks Creek Park and relocating it 50-75 feet away from the stream and converting it to porous gravel. The project has approved funding through Ecology Capacity grants funds and is seeking additional grant funding through 4 other grant sources. The project will demonstrate LID measures of porous pavement and amended soils. The existing road will be completely removed and all the area that is currently planted with grass will have its soils amended, and a riparian planting placed in its stead. The project will also serve as a leadership example of how we would like to see other homeowners along Clarks Creek treat their riparian shorelines. This project supports both on Clarks Creek while showing a different approach to shoreline development. Porous Alley Initiative: Kick starting this program is Ecology Capacity grant funding. The City of Puyallup spends approximately $75,000/year on the 7 miles of gravel alleys within the City, which are primarily in the valley area. Besides being a recurring maintenance cost, these alleys are commonly a cause of localized stormwater ponding, which results in a high number of complaints from citizens. With the current available funding, the City hopes to install porous asphalt pavement on approximately 1,600 linear feet of alleys. We hope to include the two alleys adjacent to the 8th Ave NW LID Retrofit project as part of that total to make that neighborhood a more complete LID Retrofit neighborhood example. We anticipate that City crews will be able to conduct the excavation, geotextile placement and permeable base placement for this project. A paving contractor will be hired to install the choker course and porous asphalt. We are confident that in addition to minimizing the maintenance issues associated with gravel driveways, we will significantly improve surface water conditions through this program. We anticipate this will be an ongoing project until all alleys are converted. ---PAGE BREAK--- Low Impact Development (LID): Current Practice and Barriers to Implementation March 31, 2011 Stewardship Partners/Russell Family Foundation: Stewardship Partners obtained a grant from the Russell Family Foundation to install rain gardens at the remaining residences and apartment complex within the 8th Ave NW LID Retrofit project. Stewardship Partners is anticipating a May date for installation of these rain gardens. In addition to the rain gardens, Stewardship Partners will be conducting a rain garden class at the WSU Puyallup campus on May 12. Finally, Stewardship Partners is proceeding with plans to install rain gardens at Karshner Elementary, near the 8th Ave NW LID Retrofit site. 8th Ave NW LID Retrofit: This project was conceived at the first rain garden project on 8th Ave NW. The project is located between 11th and 9th Streets NW on 8th Ave NW. Grant funding was officially received in February 2011, allowing final design and permit documents to be developed for a construction package. That process is now underway. The project will take a street with minimal storm drainage and a history of localized flooding due to a virtually 100% impervious right-or-way and convert it to a 100% porous right-of-way. The soils at the site, as demonstrated by the well functioning rain gardens, are well draining. The entire ROW will be redeveloped with porous asphalt road, rain gardens in the ROW and porous sidewalks. The road will be narrower than normal City of Puyallup standards, both as a traffic calming measure but also as a principle of LID. The street will be curvilinear, also to provide some traffic calming. The stormwater system will be a belt and suspenders + second set of suspenders system. The pavement section is designed to contain the 100-year storm event, but should it fail surface water will be directed to the adjacent rain gardens, which are also designed to contain the 100-year storm. If by chance both of those systems fail, a storm line constructed as part of the project will allow overflows from the interconnected rain gardens to enter the traditional stormwater collection system. Porous Shoulder Rehabilitation: As a pilot repair methodology, a known drainage issue at the intersection of 9th Ave NW and 11th St SW will be repaired by replacing the existing gravel shoulder with a porous gravel section similar to the pavement section below porous pavement roads. This will allow this several hundred square foot area to readily drain into the well draining soils of the area instead of building up and crossing over the intersection. If successful, this process could be utilized in many of the valley areas of the City where similar problems occur. Silver and Meeker Creek Restoration: The Silver and Meeker Creek Riparian Restoration project is primarily a planting and maintenance project. Hundreds of trees have been planted along several thousand feet of stream bank for this project. Trees are a good non-structural stormwater feature. Some jurisdictions are providing stormwater credits for planting trees, recognizing their value in that regard. The trees will also provide shade for both streams, helping cool the water and prevent undesirable weed growth. For Meeker Creek in particular, the trees ---PAGE BREAK--- Low Impact Development (LID): Current Practice and Barriers to Implementation March 31, 2011 will make the stream less desirable for water fowl, which are major contributors to the fecal coliform issues in the stream. The project, as an ancillary benefit, is constructing soft surface trails along the riparian corridor, providing a new recreational facility for Puyallup. Meeker Creek Channel Restoration: This project is dependant upon successful acquisition of property near the confluence of Meeker Creek with Clarks Creek. Project vision includes removing Meeker Creek from its trapezoidal channel, lower the entire site to near the normal high water mark, and restoring a nature meander to the stream for this reach. In addition to providing flood storage, the project would provide substantial riparian habitat benefits, including significant tree plantings. As mentioned above, trees are good non-structural stormwater features in and of themselves. We anticipate that all soils on the site would be amended per T5.13 BMP as well. 12th Ave SE Regional Stormwater Facility: This project is dependant upon successful acquisition of property near Shaw Road and containing Deer Creek. While the primary function of the project will be as a stormwater detention facility, conceptual plan is to restore Deer Creek and associated riparian habitat within the facility. In addition to significant riparian plantings along the creek alignment, all disturbed soils will be amended per T5.13 BMP. This would include the potential soccer fields within the detention facility area, although the sand content will be higher for those uses. Goals and Metrics Rain Garden Program The City of Puyallup has a well recognized program for rain garden implementation, and is a contributing partner to Stewardship Partners 12,000 Rain Garden project through installation of our neighborhood rain gardens and collaboration on Stewardship Partners Russell Family Foundation grant efforts. Some of the goals of the program include: • Educate the public on stormwater and how rain gardens can help improve stormwater conditions. • Leverage rain garden events to cover many related stormwater and sustainability practices such as storm drain markings, car wash demonstrations, riparian plantings, porous driveways, natural yard care, etc. • Involve local schools in the projects, specifically targeting 5-6 grade levels. • Leverage resources through solicitation of volunteers, donations and contributions in kind. • Utilize as many forms of media as willing to spread the message to a broader audience. • Involve multiple design professionals in the program to broaden the experience base of designer knowledgeable of rain gardens and of our program. ---PAGE BREAK--- Low Impact Development (LID): Current Practice and Barriers to Implementation March 31, 2011 • Involve multiple contractors in the construction of the rain gardens to broaden the experience base of contractors knowledgeable of rain gardens and of our program. This need is more critical than design professionals, as many designers are familiar with rain gardens, but the contracting sector is lagging. • Demystify rain garden maintenance and take fear of the unknown out of the equation. Obtain signed and recorded maintenance agreements for all rain gardens. • Promote acceptance in public right-of-ways of rain garden installations, particularly on local access roads. • Long term, transition rain garden program from 100% subsidy program to a cost share basis to eventually a stormwater credit or rebate program. • Increase the number of rain gardens installed by 20-30% annually. • Track rain garden installations on the City’s GIS database. Porous Alley Initiative The City is just beginning to undertake this project. We are planning on a modest 1,600 linear feet of alleys for the first year’s program. As more funding becomes available and the program gains wider acceptance, we will hopefully ramp this program up. Goals include: • Conversion of 1,600 linear feet of currently gravel alley to porous asphalt in 2011. • Establish conversion as part of regular maintenance plan, eventually converting all 7 miles of gravel alleys to porous asphalt. • Utilize City crews for all excavation, subgrade preparation, geotextile and permeable base placement. • In normal budget years, utilize paving contract to have paver install choker course and porous asphalt. • In 2011, special contract for paver will have to be established. • Track all installations on City’s GIS database. • Add all completed projects to the City’s street sweeping schedule. Program Metrics The City is utilizing a simple, easy to understand metric and publishing that on the stormwater section of the website. The method is not rigorously correct, but does provide an estimation of rainwater diverted from the stormwater system. A model, such as could be used to track actual water diverted from the stormwater system, but doing so would add multiple layers of complexity without adding significant value to the program’s intent. The City’s program assumes that all rain fall entering the LID BMP is diverted from the stormwater system, whether that is to groundwater or the sanitary sewer system, as is the case with a lot of rain water harvesting. Based on that assumption, the collective LID BMPs surface area is multiplied by the annual rainfall for Puyallup in feet to obtain total cubic feet of water. This number is then converted over to gallons and is the number posted on the website. We are calling our program “Get Disconnected” and details can be found on the City’s website at http://www.cityofpuyallup.org/services/development-services/puyallups-stormwater- management-program/citizens-guide-to-protecting-waters/disconnected/. ---PAGE BREAK--- Low Impact Development (LID): Current Practice and Barriers to Implementation March 31, 2011 We arbitrarily established a goal of 9 million gallons of water diverted as our 2011 goal. With the current projects we have been able to verify, we are currently at 2.6 million gallons a year. See Figure 1 below for projects included in the current tally. If the City is able to complete all the projects planned for this coming year, we should be very close to meeting our goals, even without including any potential private development projects which may use LID measures. Development Services has been coordinating closely with Stormwater to account for LID measures being proposed in private development projects. Figure 1-Current City of Puyallup "Get Disconnected" Projects ---PAGE BREAK--- Low Impact Development (LID): Current Practice and Barriers to Implementation March 31, 2011 LID Implementation Plan The City of Puyallup is watching the Ecology NPDES Phase II Permit reissuance process closely. It is our understanding that draft language will be forthcoming soon for the two major areas of change in the next permit, LID Implementation and water quality monitoring. The City of Puyallup has been trying to achieve as much LID implementation on a voluntary basis as it can. We have been moderately successful with this effort. It is likely that the next permit will require LID to be mandatory. However, what form this mandate will take is anyone’s guess at this point. The City is prepared to begin making proactive changes after the draft permit language has been published and a reaction to it has been made by all stakeholders. To my knowledge, the City has no plans to unilaterally adopt LID measures as mandatory at this time or prior to permit mandating LID use. The lone exception to that may come with implementation of the Dissolved Oxygen TMDL for Clarks Creek, which has toyed with the concept of LID implementation within the Clarks Creek basin as one of its measures. Barriers to LID Implementation: Introduction The barriers to effective, widespread LID implementation are legion. This is to be expected with any new program, but some facets of LID face higher hurdles than others. I’m including a fairly list of potential barriers, but I’m sure it is by no means exhaustive. Unfortunately, in the real world of bureaucratic decision making, it only takes one “NO” from one of the regulatory, design, owner, or contractor sides to potentially kill the use of an LID BMP. I know of a case where a large rain garden was designed for a homeowner. The rain garden was a cost effective solution because of the size of the impervious area being served and the water quality treatment that would be required by conventional means. After a less than easy approval process for the rain garden design, the owner decided that a rain garden was not for him. His excuse was that he was allergic to mosquitoes, and he couldn’t have a rain garden on his home site. This was despite the fact that the standard stormwater measures would have ponded much more water for a much longer time, and that the rain garden would be drained in less than 24 hours, a too short of a timeframe for mosquito gestation. Thus, after a series of battles to gain acceptance of the rain garden from a reluctant architect, a regulatory agency that put numerous hurdles up to approval, and winning over an extremely reluctant contractor, the owner was able to veto based on misinformation. In many ways, this is a succinct description of the barriers to LID implementation. In no particular order, here are some of my observed barriers to LID implementation. Any one of these facets could apply to anyone in the major groups listed above: regulatory; designer; owner; contractor. Thus there are many ways to get to NO, but only one path to get to yes. ---PAGE BREAK--- Low Impact Development (LID): Current Practice and Barriers to Implementation March 31, 2011 Community Acceptance and Understanding: I don’t like it: It really isn’t over simplifying it to say that some people just don’t like LID, they don’t think it works, and they just aren’t going to do it. I’ve been trying to gain acceptance of porous asphalt for well over a decade now, and I’m no longer surprised to hear people make statements like “We’ll never have porous asphalt on my streets”. Unfortunately, this kind of thought process has been coming from the very people in charge, with the ability to make decisions about changes. The obvious thing to do is to get the information out to these people so they can start seeing that these are all viable solutions to our stormwater problems. In fact, we can’t keep operating the way we have for decades because that is what got us to this position in the first place. You won’t be able to convert everybody; in fact you probably won’t even be able to convert a majority in the beginning. But the word has to be spread; status quo is no longer acceptable. Continuing education and outreach to staff, the design community, contractors and particularly politicians will help start turning this obstacle around. I don’t know it: These people aren’t aware of LID practices, are not comfortable with this new way of addressing stormwater, and generally are afraid of the unknown. On this front I think we are beginning to make headway. With the help of the Puget Sound Partnership and WSU, regular LID training sessions are being held for design and construction professionals at the WSU Puyallup campus. UW also has an LID course. The demand is great however, and I heard that this year’s WSU LID Technical Workshops have already been sold out, months in advance of the actual classes. The demand is definitely there, I’m not sure we’re keeping up with the supply end. LID practice is a shifting target. Curtis Hinman is working on revising the Rain Garden Handbook based on some of the lessons he is learning at the WSU Puyallup facility. We have been constantly revising and updating the porous asphalt specifications and process. New certification programs for pervious concrete installers have been initiated. A critical mass is developing with the design community. What is currently lagging is regulatory agency and construction contractor knowledge about LID implementation. Those areas will need attention. Regulatory agencies need to know the critical aspects of LID implementation so that they don’t over regulate the practices out of fear or ignorance. A firm grasp of the BMP will allow sound judgment on what really matters in the design and in the field. Contractors need to have experience installing LID. Contractors can’t make money installing things they don’t know how to do, and thus can’t do efficiently. This is part of the basis of our rain garden program change. We want to give some contractors the chance to learn how to do this work in a low risk environment and begin deepening the talent pool. Based on my experience, the talent pool is pretty shallow right now. ---PAGE BREAK--- Low Impact Development (LID): Current Practice and Barriers to Implementation March 31, 2011 I don’t understand it: These people are aware of LID techniques but have not yet been fully exposed to its practice. In the regulatory arena, this results in overly cumbersome and difficult regulations required to implement LID BMPs. Unfortunately, when this bumps up against the designer who doesn’t know it or the owner who doesn’t like it, the hurdle becomes a decision point in favor of the status quo. It is easier to do what is familiar and “normal” than venture out into a new area, thus conventional ideas win. In the case of an owner, I don’t understand it is no better than I don’t like it if the owner is not willing to be educated. This happened at a large parking lot project in Puyallup that would have been a prime opportunity for porous pavement, but the owners didn’t understand the BMP. For designers, if they don’t understand it, they won’t design it. Most designers have developed experience with standard BMP practices which has come at a cost. They are not willing to proceed with additional expense when there is a standard BMP practice available as an option. I have been reaching out to private development when sites which would benefit from LID practices are in the development stages to try to educate designers and owners on the benefits of LID, and try to have them incorporate them into their designs. I have not had significant success in this arena as of now. Ecology, Puget Sound Partnership and others can help with the I don’t understand its, and there are many efforts underway. Some of the ways the current programs can be improved is by providing more specific guidelines on BMP requirements and assistance on how to design, maintain and inspect these facilities. Specific sources are helpful, like where I can obtain compost that would be suitable for bioretention facilities, how do I inspect and test for porous pavements, and what reasonable requirements that can be enforced locally without special testing or equipment be utilized to verify proper design and construction of BMPs? I can’t afford it: There is a common misconception in the community at large that LID measures are more expensive. This is basically a subset of the groups above. Generally speaking, most LID measures, when properly designed and constructed and compared accurately to the alternative design are at least cost neutral. In many cases, particularly if using the current 2005 Manual detention standard, LID will come out far more cost effective. For example, if porous pavements and rain gardens were used to completely infiltrate a site’s stormwater, the additional cost of porous pavement section to standard pavement section will be 50-75% more. The porous option, however, does not require catch basin, conveyance pipes, control structures, water quality treatment system, land for a detention basin (which might be several lots for forested vs developed), fencing, maintenance roads, etc. Ultimately, maintenance costs for some of these systems will also be less than their alternatives. Porous asphalt, for example, does not need to be chip sealed every 7 years to lengthen its life space and its maintenance is nothing more than vacuum sweeping, which every jurisdiction should be including in their stormwater program anyway. As with many of the above issues, some education is underway, and is whittling away at the ignorance of life cycle costs of LID. No matter ---PAGE BREAK--- Low Impact Development (LID): Current Practice and Barriers to Implementation March 31, 2011 how much training, education and examples are put out there; some will be late adopters no matter what we do. Regulatory Barriers: Credits for LID Appendix C of the current 2005 Manual does not allow credits commensurate with actual performance of LID BMPs. For example, porous pavements, if utilized on a private project, will only receive a 50% credit for flow reduction. Apparently the philosophy behind this reduced requirement is that private owners will not effectively maintain their pavement and it will become less effective at reducing volume. When the odds are so stacked against voluntary implementation of LID practices, this disincentive makes it highly unlikely that private developers will proceed with this option. Flow modeling credits that more accurately reflect that actual performance of LID measures needs to be allowed in the Manual. Doug Beyerlein recently provided these modeling results for LID measures.

One of the ways to do this is simply not to create as much paved area. Current fire codes, as implemented in Puyallup and many other jurisdictions, require very wide pavement sections for roads. Typical street widths in Puyallup are around 38 feet, in part, due to fire code requirements. Intuitively, with very wide streets, the right-of-way needs to be even wider to accommodate curb, gutter, sidewalk and any planting strip envisioned. Eventually you come up with the standard 60 foot or more standard right-of- ---PAGE BREAK--- Low Impact Development (LID): Current Practice and Barriers to Implementation March 31, 2011 way. This type of standard obviously creates a lot of public land with almost all of it being impervious. Also, it makes cities less dense by utilizing large sections of land for the transportation grid which could have been used for housing or buildings. Dense development is sustainable development: it prevents urban sprawl and loss of rural farmland by maximizing the utilization of already urbanized areas. It is also efficient use of resources. Keeping development compact can allow much less infrastructure to support the same number of people in a less dense development. Hopefully, once development reaches a critical mass, mass transit becomes viable, personal automobiles become less of a necessity, and walking can become a reasonable form of transportation for many daily activities. Narrower streets can become a part of this vision of a more sustainable future. Arterials, collectors and other higher volume streets should maintain the configuration they currently enjoy, but local streets and cul-de-sacs should be examined for opportunities to make them narrower than current fire codes will allow. In the classic grid road system, multiple points of access for each structure via streets and alleys, should allow for acceptable safety conditions and narrower streets. Vesting Laws LID for new construction and redevelopment will not fix the past practices of the last 150 years, but it has even less of chance of making a significant difference with the vesting laws currently in place. Developers do need to have some assurance that the target won’t move during the process of permitting and constructing their project, however in practice what happens is developers rush to get vested in a project, even if they were not planning on building immediately. They then sit on the permits for as absolutely long as they can or until economic conditions are good for the project. With state laws allowing 5 years to complete a plat with up to 3 one year extensions, projects can actually be constructed up to 10 years later under rules predating that. An example of this from the land use perspective, is the outskirts of Orting, which is zoned rural in Pierce County zoning, but is almost entirely moderate density single family housing due to vested developments which beat the deadline for the 1995 Comprehensive Plan update. Similarly, we can now expect many projects to developed over the next 10 years that will not comply with the 2005 Manual because they were vested before January 16, 2009 or were under 1 acre for those jurisdictions utilizing that exemption. It would make sense for the time line to be shorter AND to require that consistent progress be made towards finalizing construction of the project. For most projects, this would mean about 3 years to me. To anticipate one of the objections, that we would be discouraging development, I would say quite the contrary. For projects that are viable and ready to go, you are encouraging them strongly to get it done now lest you have to stop, redesign and resubmit under new regulations. Environmental Currently, many LID BMPs are prohibited from use in areas with high ground water tables or poor soils. Rain gardens, for instance, have a 3 foot separation requirement from high ground water for larger systems. This requirement appears to neglect the water quality treatment provided through the soil/root media of the rain gardens ---PAGE BREAK--- Low Impact Development (LID): Current Practice and Barriers to Implementation March 31, 2011 themselves. Guidance for permeable pavements has been similar, although I believe the LID committee finally recommended that ground water could be within a foot of bottom of the pavement section. Again, recognition of the treatment capabilities of the pavement section itself appears to be neglected. The efforts of the LID at WSU Puyallup will hopefully be addressing these issues with their experiments and studies. In the meantime, these potentially excessive restrictions on LID use will likely restrict application of LID BMPs in areas where they would ultimately be beneficial. When other studies from other areas indicate effective water quality treatment through these systems AND we know the status quo is the path to more pollution, we should error in favor of the systems which are most likely to help us. While I’ve listed this as an environmental concern, ultimately it is a regulatory one. Most jurisdictions have adopted the 2005 Manual, including the LID Appendix. With the LID practice being so fluid, Ecology must find a way to keep Appendix C updated on a frequent basis until the state of the art stabilizes somewhat. The current version of Appendix C, I believe, has been amended at least once since its publication, but is still behind the recommendations of the LID committee. Conclusions I would not have thought I would come to this conclusion 2 years ago, when I was still a member of the City of Puyallup’s Planning Commission. I was pretty firm in my belief that we were not ready to make LID mandatory yet. There are still many questions to answer, and the practice of LID is in flux. Nonetheless, we have more than reasonable assurance through studies and experience in other parts of the world that LID practices are beneficial to stormwater and should be adopted. After taking a look at the obstacles that are out there to implementing LID, I don’t think LID will ever be able to make any in roads on storm water quality and quantity unless it is mandatory everywhere. Realizing that new construction and redevelopment alone will not correct our current deficiencies, retrofitting needs to be a key goal as well. Until LID becomes the norm rather than the exception, we will be fighting an uphill battle. LID needs to be adopted by public works departments, looking at failing roads as an opportunity to retrofit to porous pavements instead of chip seals and overlays. Narrower roads can allow for rain garden installations within existing right-of-ways. A large portion of our impervious surface within the Puget Sound basin is public roads (the City of Puyallup alone has 150 miles of streets or around 620 acres of impervious surface). LID retrofits of public roads needs to become the rule. Finally, I know that a large amount of time was spent last year on determining what “where feasible” meant in regards to LID implementation. I understand that my opinion will be regarded as naïve and disregarding political reality, but quite practically, if new construction or development occurs, unequivocally some form of LID can be implemented regardless of soil, slope or type of project. Green roofs can be installed on any building, soils can be amended with organics in any disturbed area, and rain water harvesting can occur anywhere stormwater is generated. I believe that LID should be ---PAGE BREAK--- Low Impact Development (LID): Current Practice and Barriers to Implementation March 31, 2011 mandated to the maximum extent possible up to 100% retention of stormwater on site. Specific BMPs may not be suitable to a particular site, but other BMPs should be implemented in their place, with the universal three above utilized if no other BMPs can be effectively implemented on the site. The goal should always been 100% retention of stormwater on site, with no further LID BMPs required once you reach 100%. Otherwise, all available BMPs would be utilized to the maximum extent until available BMPs are exhausted. Respectfully Submitted, Mark A. Palmer, P.E., LEED® AP Stormwater Engineer, City of Puyallup ---PAGE BREAK--- City of Puyallup Future Stormwater and SWMP Effectiveness Monitoring Plan Prepared for City of Puyallup, WA December, 2010 ---PAGE BREAK--- 2 Section 1 Monitoring Overview This section provides a brief overview of the monitoring requirements that are set forth in the Washington State Phase II Municipal Stormwater Permit for Western Washington (Phase II Permit). 1.1 Current Permit Monitoring Requirements The Phase II Permit regulates stormwater discharges for small municipal separate storm sewer systems (MS4s) as established in Title 40 CFR, part 122.26. The Phase II Permit, issued in 2007 and modified in 2009, includes requirements for permittees to prepare to conduct a monitoring program in future permits. The Phase II Monitoring Program described in Section S8.C includes two types of monitoring: 1. Stormwater Monitoring (S8.C.1.a) 2. Stormwater Management Program (SWMP) Effectiveness Monitoring/Targeted SWMP Effectiveness Monitoring (S8.C.1.b) Stormwater Monitoring (S8.C.1.a) requires permittees to identify sites suitable for monitoring stormwater discharges based on jurisdictional size and land use types, and on known water quality problems and/or targeted areas of interest for future monitoring. SWMP Effectiveness Monitoring (S8.C.1.b) requires permittees to identify questions that monitoring may answer to determine the effectiveness of specific components of their Stormwater Management Program (SWMP). The permittee must identify sites for monitoring and create monitoring plans to answer at least two effectiveness questions. This document covers effectiveness monitoring as required for S8.C.1.b; stormwater monitoring (S8.C.1.a) is described in a separate monitoring plan. 1.2 Future Permit Monitoring Requirements This monitoring plan was prepared to meet the requirements of the current (2007) Phase II Permit, as noted above. However, the next Phase II Permit, which is scheduled to be issued in 2012, may contain monitoring requirements substantially different from those envisioned in the current Permit. Thus, this monitoring plan should be regarded as tentative and subject to change based on the next Phase II Permit. In 2008, Ecology convened the Puget Sound Stormwater Workgroup (SWG) to develop a comprehensive, sustainable, stormwater monitoring strategy for Puget Sound, as well as monitoring requirements for the next municipal stormwater NPDES permits. The SWG members represent caucuses of local, state, and federal agencies, environmental and business organizations, tribes and agriculture. The SWG submitted the comprehensive strategy in July 2010 to Ecology (in a document titled 2010 Stormwater Monitoring and Assessment Strategy for the Puget Sound Region). Based on this strategy, the SWG submitted monitoring recommendations for the next NPDES Phase I and II permits on October 29, 2010, in a document titled Recommendations for Municipal Stormwater Permit Monitoring). ---PAGE BREAK--- 3 The SWG recommends that Ecology designate an independent entity to administer the stormwater- related monitoring and assessment activities in the next municipal stormwater permits. This recommendation is called the “pay-in” option. The SWG recommended receiving water monitoring rather than the outfall monitoring described in the current permits. Moreover, the SWG recommended that the regional entity (rather than by each permitee) administer the program effectiveness monitoring and focus on questions of regional significance. More information on the SWG is available at http://www.ecy.wa.gov/programs/wq/psmonitoring/swworkgroup.html. ---PAGE BREAK--- 4 Section 2 Targeted Stormwater Program Effectiveness Questions Phase II Permit condition S8.C.1.requires that each permittee prepare a monitoring plan to address two questions related to the effectiveness of the permittee’s stormwater management program. The monitoring plan must contain the following elements: • A statement of the question, an explanation of how and why the issue is significant to the permittee and a discussion of whether and how the results of the monitoring may be significant to other MS4s. • A specific hypothesis about the issue or management actions that will be tested. • Specific parameters or attributes to be measures. • Expected modifications to management actions depending on the outcome of hypothesis testing. The City’s proposed effectiveness questions and monitoring approach are described below. As noted above, the City understands that the next version of the Phase II Permit may contain monitoring requirements substantially different from those envisioned in the current Phase II Permit. The City may revise these effectiveness questions and/or monitoring strategies after the next Phase II Permit has been issued. Question 1- Will retrofitting alleys with porous pavement substantially reduce runoff? Problem Statement/Description: Creation of impervious surfaces has been identified as a major cause of the flooding, water pollution, and channel erosion problems that often accompany urbanization (National Academy of Sciences 2008). Porous pavement is designed to allow rainfall to infiltrate into the underlying soil, thereby minimizing surface runoff and related flooding, water pollution, and channel erosion problems. The City must devote substantial resources to meet NPDES flow and water quality control standards. Other MS4s are likely having similar issues. Hypothesis: Catchments with alleys covered by porous pavement will generate less surface runoff than catchments with alleys covered by traditional pavement. Specific parameters or attributes: The City will identify two small catchments with similar land uses, soils, and topography. The alleys in one of the catchments will be repaved using pervious material. The City will monitor runoff volumes from each catchment area and compare the results. Expected modifications: If monitoring determines that the areas with porous pavement substantially reduce runoff volumes then the City will more likely install porous pavement sections in alleys. ---PAGE BREAK--- 5 Question 2- Will installation of rain gardens in road rights-of-way substantially reduce runoff? Problem Statement/Description: Nearly all of the existing roads in Puyallup are covered with impervious pavement. In some areas, road runoff is directed to adjacent grassy areas with limited potential for flow and pollutant attenuation. Installing rain gardens in these grassy areas could increase infiltration and sedimentation, thereby reducing flow volumes and pollutant loads. Rain gardens are low-lying, vegetated depressions with absorbent soils that promote infiltration. Rain gardens are a popular form of stormwater mitigation, as they are easy retrofits for existing developments and are well suited for small sites, such as rights-of-ways. Many other MS4s use rain gardens and therefore are likely to have similar questions regarding their effectiveness in reducing runoff from road rights-of-way. Hypothesis: Catchments with rain gardens in the rights-of-way will have less runoff than catchments with grass in the rights-of-way. Specific parameters or attributes: The City will identify two small catchments with grass-covered rights-of- way and similar land uses, soils, and topography. Rain gardens will be installed he rights-of-way in one of the catchments. The City will monitor runoff volumes from each catchment area and compare the results. Expected modifications: If monitoring determines that the areas with rain gardens substantially reduce runoff volumes then the City may install more rain gardens in rights-of-ways in the City.
