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.

(253) 841-5597 Technical Advisor, coordination, and Permit Compliance This table should be revisited at least once per year and updated if staff assignments change. 3.3 Training The Phase II Permit requires training of Facility employees whose activities could impact stormwater quality. 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.
