City of Farmington NPDES Phase II MS4 Annual Report Reporting Period: July 1, 2011 to June 30, 2012 October 1, 2012 City of Farmington Public Works Department 800 Municipal Drive Farmington, New Mexico 87401 ---PAGE BREAK--- ---PAGE BREAK--- City of Farmington 10/01/11 MS4 Annual Report Page i EXECUTIVE SUMMARY The National Pollutant Discharge Elimination System (NPDES) Phase II rule, which was promulgated on December 8, 1999, regulated small MS4s serving a population of less than 100,000 people in urbanized areas. The final rule requires that all MS4s located within urbanized areas as defined by the Bureau of the Census automatically comply with the Phase II Stormwater regulations by developing and implementing a Stormwater Management Program. The Program must reduce the discharge of pollutants to the Maximum Extent Practicable (MEP), protect water quality, and satisfy the appropriate water quality requirements of the Clean Water Act (CWA). The Program also requires the development of a Stormwater Management Program (SWMP) Plan that is comprised of the following six minimum control measures: 1. Public Education and Outreach, 2. Public Participation/Involvement, 3. Illicit Discharge Detection and Elimination, 4. Construction Site Stormwater Runoff Control, 5. Post-Construction Stormwater Management in New Development and Redevelopment, and 6. Pollution Prevention/Good Housekeeping for Municipal Operations. A significant portion of the City of Farmington, New Mexico, met the definition of an urbanized area in the 2000 Census (http://www.census.gov). As a result, the City of Farmington is required to meet the Phase II Stormwater regulations. The 1999 NPDES Phase II rule required that the City of Farmington develop a SWMP Plan and submit a draft Notice of Intent (NOI) to the United States Environmental Protection Agency (USEPA) by March 10, 2003. The City of Farmington submitted a draft NOI to apply for coverage under the General Permit for Discharges from Small MS4s (Permit No. NMR040000). The City also developed the original City of Farmington Stormwater Management Plan that was subsequently approved by Farmington City Council in March 2003. The Final NPDES Phase II rule was signed and issued on September 29, 2006, and the permit became effective on January 1, 2007 and expires on June 30, 2012. As municipalities are currently awaiting the new NPDES permit, the current permit will be extended until such time as the new permit is available. During February and March 2007, the City of Farmington re-evaluated and updated Stormwater Management Plan. The permit requires that the City of Farmington submit an MS4 Annual Report for the previous reporting period (July 1st through June 30th) by October 1st of each year for the life of the permit (2008 to 2012). The annual report includes the following:  The status of compliance with permit conditions, an assessment of the appropriateness of the identified best management practices, progress towards achieving the statutory goal of reducing the discharge of pollutants to the MEP, and the measurable goals for each of the minimum control measures;  Results of information collected and analyzed, if any, during the reporting period, including monitoring data used to assess the success of the program at reducing the discharge of pollutants to the MEP; ---PAGE BREAK--- City of Farmington 10/01/11 MS4 Annual Report Page ii  A summary of the stormwater activities the City of Farmington plans to undertake during the next reporting cycle (including an implementation schedule);  Proposed changes to the SWMP Plan, including changes to any Best Management Practices (BMPs) or any identified measurable goals that apply to the program elements;  Description and schedule for implementation of additional BMPs that may be necessary, based on new information or monitoring results, to ensure compliance with applicable Total Maximum Daily Loads (TMDL);  Notice if the City of Farmington is relying on another government entity to satisfy some of the permit obligations; and  A brief summary of any issues raised by the public on the draft Annual Report and any proposed changes to the SWMP Plan, along with the City of Farmington’s responses to the public comments. The permit requires a public comment period for at least thirty (30) days prior to the submission of the report. The City of Farmington provided a review and comment opportunity. Public notices for the review and comment period were published in the Farmington Daily Times on Sunday, September 5th and 12th. All comments received were considered and addressed before the annual report was finalized. The final MS4 Annual Report was submitted to the following authorities: U.S. EPA, Region 6 Compliance Assurance and Enforcement Division Water Enforcement Branch (6EN-WC) 1445 Ross Avenue Dallas, TX 75202-2733 Program Manager Point Source Regulations Section Surface Water Quality Bureau New Mexico Environment Department P.O.

Implementation Status The City of Farmington’s Stormwater Management Program (SWMP) Plan contains all the measurable goals for the Public Education and Outreach program area that were planned during the five-year permit period (2007 through 2012). However, the focus of this annual Municipal Separate Storm Sewer Systems (MS4) Annual Report is the status of those goals planned during this reporting period (July 1, 2011 to June 30, 2012), a summary of goals planned for the next reporting period (July 1, 2012 to June 30, 2013), and any changes proposed to the goals in the SWMP Plan. Table 1-1 summarizes the status of the Public Education and Outreach goals planned during this reporting period as well as the status on any goals where work has already begun in preparation for future deliverables. 1.2. Overall Compliance with Permit Conditions The City of Farmington worked to complete the goals planned during this reporting period for Public Education and Outreach program area. Educational information and booths were offered to the residential community and construction industry. The City’s website is actively reviewed to ensure the stormwater information provided is accurate and up to date. During the reporting cycle changes were made to the website as needed to provide storm water information. Please see section 1.2.3 for further information. The City continues its active participation and partnerships with groups in the region and is always interested in partnerships with new groups and organizations. Employees attended regular meetings held by Animas Watershed Group and San Juan Watershed Group. More information can be found in section 1.2.4 of this report. The following sections provide information collected and analyzed during this reporting period. 1.3. Results of Information Collected and Analyzed During the Reporting Period The following sections provide information collected and analyzed during this reporting period. Some historical information has been left in from previous reports. 1.3.1. Stormwater Training and Outreach – Residential Focus Public Meetings and Comment Periods The public comment period on the MS4 report was held from 8/26/12 to 9/26/12 and three notices were included in the Farmington Daily Times on Sunday August 26th, Monday August 27th, and Sunday September 2nd. A public meeting was not held in this reporting year. As is consistent with the NPDES permit requirements, there has been no significant interest in public comment periods to justify a public meeting. In the case that the city does see a significant interest from the public during the commenting periods or in any time during the following year regarding the SWMP, MS4 report, or other stormwater quality issues, the city will plan for a public meeting. The last stormwater public meeting held, in November of 2009, had one attendee despite radio announcements, multiple postings in the daily times, and numerous flyers. ---PAGE BREAK--- 10/01/11 MS4 Annual Report Page 4 Residential Training Workshops No residential training workshops were held this reporting cycle. Residential Promotions The City of Farmington promoted several stormwater educational activities during this reporting period. Promotions are summarized below and examples are provided in Appendix B. ▪ Farmington Clean & Beautiful – The city held its Adopt a Highway and Refrigerator day programs, as well as the waste collection days to reach out to citizens to keep the city clean. See section 2.3.2 for more information. ▪ City Buses. The City of Farmington operates the Red Apple Transit within the city and has routes to the City of Aztec and the City of Bloomfield. Two of the nine buses have placards on the back that remind the community that stormwater is not treated and to keep pollutants out of the storm drains. ▪ Brochures. The city continues to make readily available a variety of brochures covering the following topics: preventing storm water runoff, xeriscape designs, rain gardens, stormwater quality, suitable plants for desert climates, and rain harvesting. These brochures are available at the City and are handed out during educational events such as the Home Show Expo and Water Fair. The Preventing Storm Water Runoff brochure is also available online. ▪ Presentations. The water fair was cancelled this year by the San Juan Water Commission. The City was prepared to present four booths to 5th graders. ▪ Press Release –Press releases were held for the Farmington Clean and Beautiful program and Dumpster Weekend. ▪ Demonstration Projects. No new additional demonstration projects were added this cycle. In the last several years the city has completed demonstration projects for xeriscape pond design and permeable concrete. See previous reports for more in depth discussions and photos. ▪ Informational Booths. The City of Farmington participated in several booths throughout the reporting year.  This reporting cycle the water fair was cancelled due to a lack of participation from booth presenters. The city was prepared to host four booths and will plan on presenting next year.  The City once again participated in the Home Show Expo in March of 2012. This will be further addressed in the following section 1.2.2 Stormwater Training and Outreach – Construction Focus, though the event does provide residential information as well. 1.3.2. Stormwater Training and Outreach – Construction Focus Public Meetings and Comment Periods The public comment period on the MS4 report was from 8/26/12 to 9/26/12 and three notices were included in the Farmington Daily Times on Sunday August 26th, Monday August 27th, and Sunday September 2nd. As is stated in the NPDES permit, upon showing of significant interest, the MS4 coordinator is encouraged to hold a public meeting. No meeting was held this last reporting year, but will be scheduled in the case of an increase in public interest. Construction-related Training Workshops ---PAGE BREAK--- 10/01/11 MS4 Annual Report Page 5 No classes were held in the reporting period of 2011-2012.

The MS4 was also available at the booth during periods to speak with people about these topics. Some of these brochures can be found in Appendix B-2. 1.3.3. City of Farmington Website The City of Farmington continues to update and provide the most up to date information on its stormwater website. The draft report for the 2011-2012 report was made available during the month of September. A direct link to the EPA’s guide was also made available. http://fmtn.org/city_government/public_works/stormwater_management.html The site includes program documents, residential information, construction BMP links, links, industrial links, and who to contact at the City for stormwater related questions. At the end of the comment period, the final 2011-2012 report was made available. See Appendix B-5 for the most current site image at the time of this report submittal. During previous periods, the site has been used to announce public meetings, such as the ones held on November 19th of 2009 to discuss storm water issues and concerns around the city. Such events have been promoted on the City’s Stormwater page along with comment forms. 1.3.4. Initiate Partnerships with Interested Groups and Organizations The City of Farmington continues to actively participate with two local watershed planning groups in the area; the Animas Watershed Project (AWP) and the San Juan Watershed Group (SJWG). ---PAGE BREAK--- 10/01/11 MS4 Annual Report Page 6 City of Farmington staff members regularly attended the AWP meetings and participated on AWP committees throughout the year. The city as participated not only in meetings but also City of Farmington staff members serve in committee positions and have reviewed and written material within the watershed management plan. The City continues to stay involved with the SJWG as well and attend meetings. The City of Farmington is still working with Kirtland as it aims to connect its proposed sanitary system to the City’s wastewater plant. 1.4. Activities Planned for the Next Reporting Cycle In the next reporting period, the City of Farmington will continue to participate with local watershed groups and to attend events best suited towards educating the public about storm water quality. The Water Fair was found to be a very effective way to involve youth and help them understand more about the water in their rivers and streets. The City plans to attend the Water Fair in 2012. The city will continue to look for the best venues to involve and educate the public further regarding storm water quality. The City will focus on expanding partnerships, providing educational sessions for city employees, and improving educational information for construction and post-construction Best Management Practices (BMPs). A summary of the planned goals and activities for the next reporting period is contained in Table 1-1. 1.5. Proposed Changes The proposed changes for the Public Education and Outreach goals are summarized in Table 1-1. The city plans to hold training for City Council and relevant departments in year 5. 1.6. Permit Obligations The City of Farmington does not rely on another government entity to submit information necessary to satisfy permit obligations; however, the City of Farmington does cooperate with other local organizations to achieve some SWMP Plan goals. For example, the City of Farmington works with San Juan College, New Mexico Department of Transportation, San Juan County, the City of Aztec, and the City of Bloomfield to best utilize local programs and resources. 1.7.

Implementation Status Table 2-3 contains the status of the Public Involvement and Participation goals planned during this reporting period as well as the status on any goals where work has already begun in preparation for future deliverables. 2.2. Overall Compliance with Permit Conditions The City of Farmington worked to complete all the planned goals during this reporting period for the Public Involvement and Participation program area. There are several programs that invite community participation, and many of these programs improve stormwater management by reducing the amounts of waste that might otherwise end up in the stormwater sewer system if not disposed of properly. These programs were offered during this reporting period, and many local residents participated. The code compliance hotline continues to be used by residents and city officers recorded and investigated complaints this period which included illicit discharge reporting. The City continued to coordinate with scouting groups for the second year in a row to label additional storm drains with “no dumping” plaques. These scouts not only are involved in bettering the community and our water quality, but are themselves learning about these issues and concerns. A comment period for residents to provide input on the MS4 Annual Report was provided prior to submitting the MS4 annual report. No public meetings were held this reporting year, as no significant public interest mandated one per the NPDES requirements. The last public meeting was held in November of 2009 where only one resident attended. 2.3. Results of Information Collected and Analyzed During the Reporting Period The following sections provide information collected and analyzed during this reporting period. Some historical information has been left in from the first report. 2.3.1. Code Compliance Hot Line The City has code compliance officers and a code compliance hotline to record and investigate illicit discharge complaints. During this reporting period 7complaints were received. Of the 7 total complaints, 1 complaint was not substantiated, and 6 were illicit discharges. Illicit discharges were each resolved. More detailed results are provided in Section 3 Illicit Discharge Detection and Elimination. 2.3.2. Farmington Clean & Beautiful Volunteers from various civic groups, schools, and scout groups participated in the Farmington Clean & Beautiful Adopt a Highway Program. During this reporting period, there were 447 volunteers who collected 558 bags of trash. Additionally, this reporting cycle, the Farmington Clean & Beautiful Program held a refrigerator recycling day during the Non-Hazardous Waste Program day. A total of 159 refrigerators were collected and disposed of properly. ---PAGE BREAK--- 10/01/11 MS4 Annual Report Page 12 2.3.3. Household Non-Hazardous Waste Program The Farmington Parks, Recreation, and Cultural Affairs Department coordinated two Dumpster Weekend events in which volunteers collected and properly disposed of household non-hazardous waste. There were 447 total volunteers that aided in the clean and beautiful programs and waste collection. The collection results are summarized in Table 2-1. Table 2-1 Household Non-Hazardous Wastes Collected Year Total Waste from Dumpsters (tons) Fridges Metal Waste (tons) Electronics (tons) Cardboard (tons) 2011-2012 251 159 117 28 2 Yard waste collected was recycled to create compost. The compost was then used for city parks and was also made available to the public. 2.3.4. Household Hazardous Waste Program The Water/Wastewater Department of the City of Farmington and San Juan County held household hazardous waste collection events in September of 2011 and May of 2012. Residents brought in old batteries, household paints and chemicals, etc. for proper disposal. The proper disposal of these materials is crucial for the cleanliness of our streams and rivers. Batteries, chemicals, oils, and other hazardous and non-hazardous materials disposed of during these events contain: lead, nickel, nitrates, chlorites, alkaline, lithium diazinon, and cadmium, just to name a few. Collection results are summarized in Table 2-2.

Xeriscape Demonstration Garden Improvements There were no additional xeriscape demonstration projects this year. Last year the sycamore park Xeriscape Park and pond was completed. Refer to the previous year’s report. ---PAGE BREAK--- 10/01/11 MS4 Annual Report Page 13 2.3.6. Regional Forums on Climate Change and Water The city of Farmington did not participate in any regional forums on climate change and water this reporting period. 2.3.7. Recycling Program The City of Farmington continues its residential curbside recycling program. At the request of residents, waste management provides a recycling bin that is collected every other week. In meeting with residents during the Home Show Expo, the City has found that residents not only support the program, but are very happy with it. 2.3.8. Storm Drain Labeling The City coordinated with a local scouting troop to label additional storm drains this year. We still have not received the number of drains labeled by the troop this year and last, but have been told we will receive that number. It is several hundred, and roughly in the 500 labels range we believe. The MS4 coordinator was present to help scouts during the event. Once the master drainage study is complete and we have received reporting from the scouts, we will continue to label drains with scouting participation. 2.3.9. City of Farmington Website The City of Farmington continues to update the stormwater website to ensure the most relevant and up to date information is present. The website can be found at the following web address: http://www.fmtn.org/city_government/public_works/stormwater_management.html The site includes program documents, residential information, construction BMP links, links, industrial links, the most current MS4 report, and who to contact at the City for stormwater related questions. (See Section 1.3 for additional detail and Appendix B-5 for the most current website image) 2.4. Activities Planned for the Next Reporting Cycle In the next reporting period, the City of Farmington will continue to offer similar local participation events to collect and properly dispose of wastes. The City will continue to address reported code violations. It should be noted that all new City of Farmington inlets are installed with a pre-stamped no dumping label. A summary of the planned goals and activities for the next reporting period is contained in Table 2-3. 2.5. Proposed Changes There are no proposed changes from last reporting period. 2.6. Permit Obligations The City of Farmington does not rely on another government entity to submit information necessary to satisfy permit obligations; however, the City of Farmington does cooperate with other local organizations to achieve some SWMP Plan goals. For example, the City of Farmington works with Waste Management and San Juan County to best utilize local programs and resources. ---PAGE BREAK--- 10/01/11 MS4 Annual Report Page 14 2.7. Inspections and Formal Enforcement Actions Code compliance complaints were each investigated to determine if code violations existed. Violators were given 24 hours to satisfactorily address any issues. In each case, issues were resolved within the 24-hour period, so further enforcement or legal action was not pursued. The development of an official ordinance that specifically prohibits discharges into the storm drainage system and outlines penalties will allow the city to better enforce violations under its own standards. 2.8. Public Access, Review, and Comment Provisions Under the permit, the MS4 Annual Report is due October 1st of each year for the previous reporting period. The permit also requires a public comment period for at least thirty (30) days prior to the submission of the annual report. See section 1.3.1 for a discussion in meeting these goals. No comments were made by the public prior to submittal. The Annual Report was finalized and submitted to the permitting authority by October 1, 2012. ---PAGE BREAK--- 10/01/11 MS4 Annual Report Page 15 Table 2-3 Public Involvement/Participation Program Area Status for Year 5, Planned Activities for Year 6, and Proposed Goal Changes Description of Goal Department/Personnel Responsible for Implementation Targeted Audience Month in SWMP1 Year of Permit in SWMP1 GOAL #1 – Annually 1.

ILLICIT DISCHARGE DETECTION AND ELIMINATION 3.1. Implementation Status Table 3-1 summarizes the status of the Illicit Discharge Detection and Elimination (IDDE) program goals planned during this reporting period as well as the status on any goals where work has already begun in preparation for future deliverables. 3.2. Overall Compliance with Permit Conditions The measurable goals for the illicit discharge detection and elimination program area focus on locating problem areas, finding sources of the problems, removing or correcting illicit connections, and documenting actions taken. Activities during this reporting period were primarily related to sampling activities so problem areas can be identified and evaluated with other available data in an effort to determine possible sources of contaminants, the best approach to address problems, and ultimately improve water quality. This city has chosen new sampling locations at times in an attempt to isolate the problem area. The city is still working to locate the source of several traces of E. Coli that have been present for some time. See Table 3-6 for the list of completed tasks and future goals. A discussion of these results follows. 3.3. Results of Information Collected and Analyzed During the Reporting Period Results of information collected and analyzed during the reporting period for the IDDE program area are summarized in the following sections. 3.3.1. Stormwater Outfall Sampling During the reporting period (2011-2012), Animas Environmental Services, LLC (AES) continued to fulfill their contract to conduct stormwater sampling. Several decisions were made regarding revisions to the sampling locations during the year (see figure 3.1 for map with corresponding numbered locations): 1. Arroyo West of Lowe’s Parking Lot (Hood Arroyo) – Continue sampling 2. El Paso/Middle Fork Square (Porter Arroyo) – Continue sampling 3. Berg Park Location – Continue sampling 4. Municipal Operations Center (MOC) Sewer Outfall #1 – Continue sampling 5. MOC Sewer Outfall #2 – Continue sampling 6. MOC Sewer Outfall #3 – Continue sampling 7. Murray Drive Bridge Settling Pond – Continue sampling 8. South Side Lift Station #2 – Continue sampling 9. Cannery Court Location – Continue sampling 10. Intersection of Gooding and Riverview –No Longer Sampled 11. City Sports Complex Baseball Fields on Pinon Hills (Inlet of 30-inch North HDPE Pipe) – Continue Sampling (was number 15 last year) 12. City Sports Complex Baseball Fields on Pinon Hills (Outlet of 30-inch South HDPE Pipe) – No Longer Sampled 13. Glade Arroyo Culvert on South Side of Navajo Street – Continue sampling 14. South of Murray (Sweetland) – Glade Discharge – Continue Sampling ---PAGE BREAK--- 10/01/11 MS4 Annual Report Page 20 15. South Butler – New location that replaced previous sampling location #12. This new sampling location was chosen because it is a large outfall that is close to the Animas River. See previous report. 16. Airport Detention Pond – Tested as a possible source for contaminants found in Farmington Glade. – No Longer Sampled 17. Brookside/Auburn & Boyd - Tested as a possible source for contaminants found in Farmington Glade. – No Longer Sampled 18. Carwash at Dustin and 20th – No Longer Sampled 19. Vine East of Butler – Dry Weather test of continuously running water as a possible source for fecal contaminants found in South Butler Outfall. – No Longer Sampled 20. Vine at Irrigation (manhole) - Dry Weather test of continuously running water as a possible source for fecal contaminants found in South Butler Outfall. – No Longer Sampled 21. Pinon/Cedar (manhole) - Dry Weather test of continuously running water as a possible source for fecal contaminants found in South Butler Outfall. – No Longer Sampled 22. Civitan Pond Outlet – One time dry weather sampling on running water to isolate E. Coli problems that have persisted in the Glade Arroyo. Last reporting cycle, the city attempted to track down sources of contamination during the year, and added several locations (Sites 19-21). This year, The city added a location to site 22 at the outlet of a pond on the Glade arroyo. The sites added last year resulted in no fecal. The site added during this reporting cycle on the Glade did return a moderately high number for E. Coli. It was a dry test on the Civitan pond. This site was selected to aid in determining the source of pollution in the Glade arroyo. This location is one site where the city plans to collect wet weather sampling and is currently deciding on the appropriate methods to find the source upstream of this location. Other areas are also being considered on the Glade arroyo. The sampling frequency this reporting cycle was on a semiannual basis. However, because of factors such as time of day, day of the week, holding times for certain parameters, and extreme variability in rainfall events, not all outfall locations were sampled may always be tested at this frequency. The sampling numbers above should match those in the sampling results in this section and in the appendix. ---PAGE BREAK--- 10/01/11 MS4 Annual Report Page 21 Figure 3-1 Stormwater Sampling Locations – Year 4 *Only active testing sites are shown on map 22 ---PAGE BREAK--- 10/01/11 MS4 Annual Report Page 22 3.3.1.1. Baseline Sampling Event – February 2007 The following information in subsection 3.3.1.1 regarding the Baseline Sampling and commencement of the annual sampling has been left in this year’s report for background informational purposes. AES conducted baseline sampling at representative stormwater outfall locations throughout the city in February 2007. The purpose of the sampling was to assist in locating problem areas and to establish a baseline. Stormwater samples were measured in the field for pH, temperature, dissolved oxygen (DO), and specific conductivity. Laboratory samples were also collected and analyzed for chemical oxygen demand (COD), total suspended solids (TSS), oil and grease, and metals (aluminum, arsenic, cadmium, copper, iron, lead, nickel, and zinc). Stormwater analytical results from sampling conducted during February 2007 showed concentrations to be below USEPA stormwater benchmarks, with the following exceptions.  Two samples (Outfall #1 and collected from Farmington’s Municipal Operations Center (MOC) showed elevated pH readings, specific conductivity, and COD, with specific conductivity in Outfall #1 at 13.88 mS/cm, which was approximately one order of magnitude higher than other samples collected. Note that specific conductivity is reflective of total dissolved solids (TDS) and may reflect an impact from materials stored at the MOC (such as magnesium chloride). The MOC Outfall #1 also had COD concentrations of 193 mg/L, which were above the USEPA general stormwater benchmark of 120 mg/L. The pH readings from both Outfall #1 and #2 were elevated, with 9.13 and 9.62, respectively.  Elevated specific conductance levels were also detected at several sampling locations, including El Paso/Middle Fork Square, Berg Park, Murray Bridge Settling Pond, South Side Lift Station and Cannery Court. Sampling continued in this reporting period to show elevated specific conductance in nearly all the outfalls, though it should be note that elevated specific conductance levels are typical in the arid Southwest. 3.3.1.2. Stormwater Sampling – Year 4 AES completed stormwater sampling at the outfall locations during this reporting period. Stormwater flow was measured, along with rainfall data, pH, temperature, DO, and specific conductivity. Laboratory analyses included oil and grease, TSS, COD, aluminum, arsenic, cadmium, chloride, copper, iron, lead, nickel and zinc, E. Coli, and nutrients (including nitrate/nitrite, total Kjeldahl nitrogen (TKN), ammonia, and phosphorus). All sampling was conducted in accordance with Standard Operating Procedures for Sample Collection and Handling (Surface Water Quality Bureau, NMED, June 2004). Note that the hold time for fecal coliform is four hours, and any stormwater sampling conducted in the evenings or on weekends may preclude sample analyses for fecal coliform. Sample parameters, appropriate USEPA methods, and general USEPA stormwater benchmark values are noted in Table 3-1. The associated precipitation levels for stormwater sampling events are listed in Table 3-2. Stormwater analytical results for sampling events during this reporting period showed elevated concentrations (above USEPA benchmark values) at some outfall locations. In some cases, concentrations that were above benchmark values fell below benchmark values this period. The opposite is true as well in some samples. These outfall locations and elevated results are displayed in ---PAGE BREAK--- 10/01/11 MS4 Annual Report Page 23 Table 3-3. These results come from testing performed on September 22, 2010 and April 7th, 2011. The highest concentrations above benchmark values reported in last year’s report have been included in this year’s table for comparison. In cases where values have now fallen below or risen above the benchmarks, text is in blue or red respectively. Please refer to Appendix C for the full testing. In some cases, the higher value was found during September 22, 2010, but tests in April showed a much lower value. This year’s sampling results were variable. Numbers showed modest differences between the two dates.

Evaluation of Sample Results Year 4 laboratory analytical results have been tabulated in Appendix C. This appendix should be referenced when analyzing these results. Table 3-3 shows only the highest values for each ---PAGE BREAK--- 10/01/11 MS4 Annual Report Page 27 contaminant, though in some cases, these results vary widely. For example, a September reading on COD for site 1 shows a value of 790, the highest value of that contaminant we have yet recorded, and yet samples taken in April of the next year showed a COD value of 74.9 the next time, the best value ever recorded for that site and well below the benchmark. Possible reasons for such variance will be discussed further in this section. The elevated constituents found during sampling events are discussed below. Note that benchmark values are not enforceable standards; rather, they are values to assist in evaluation of stormwater impacts.  Metals –Four years of data have shown the metal contaminants to be widely variable. As has been discussed in previous reports, aluminum, zinc, and especially iron are very naturally occurring metals in the region. These sample values also seem to have some consistency related to the time of year. New Mexico is a very arid climate. Rainfall that produces actual runoff is rare in comparison to many areas in the US. When sampling is taken, it is not uncommon for that rainfall to be the first significant rainfall the region has seen for a considerable amount of time. The result is a type of first flush situation where any contaminants that have accumulated in the system during times of little or no rain, are now flushed all at once from the storm systems. The metals in the soil build up and small rains accumulate enough to aid in this process but not wash the metals away. Thus, the samples taken are at the worst conditions. There are not many rains that take water to the river, but when they do, mineral concentrations are higher. Another interesting note is that many of the samples have shown results higher during the winter. It is believed that runoff due to snowmelt may have be a factor. Snow that is exposed to metals for a longer time, and then melted, may have resulted in a higher concentration of these contaminants. The City will continue to monitor these results and research possible causes that may not be related to natural metals in the soil.  Total Suspended Solids (TSS) - Concentrations of TSS were elevated at several outfall locations and indicate soil sediments present in stormwater. Elevated TSS concentrations are typical in the arid Southwest. Sites 9 (Cannery Court) and 14 (South Murray) showed significantly higher TSS results than past results. The cit has begun to try to add samples upstream of this location to find possible reasons for this and the E. Coli samples that have been found. TSS fell lower on Site 15, South Butler, approaching much closer to benchmark values.  Specific Conductance – Most locations continue to show elevated levels of specific conductance, which is generally found to be a good measure of the concentration of total dissolved solids (TDS) and salinity. Elements whose ionic forms contribute the most to these measures include: calcium (Ca2+), magnesium (Mg2+), sodium potassium bicarbonate (HCO3-), sulfate (SO42-), and chloride Elevated specific conductance levels are typical in the arid Southwest.  Chemical Oxygen Demand (COD) – Concentrations of COD Increased significantly on site 1 and has decreased on site 5. In other cases the values have remained in a consistent range. The COD concentrations reflect the presence of other contaminants or chemicals (e.g. antifreeze or glycols) which increase the demand for dissolved oxygen in surface waters, therefore making less dissolved oxygen available for riparian or aquatic species. It should be noted that the increase on site 1 appears to be an anomaly. Testing on April 7th, 2011 showed the COD value down to 74.9, its lowest value since testing began.  E. coli – Concentrations of E. coli serve as an indicator of the presence of fecal coliform. Concentrations of E. coli were detected in stormwater samples from several outfall locations. Fecal coliform in stormwater may be associated with leaking septic systems or with the presence of livestock or domestic pet waste entering drainages or arroyos. The new location 22 was chosen because of continued contamination in sites 13 and 14 on the Glade Arroyo. The sample ---PAGE BREAK--- 10/01/11 MS4 Annual Report Page 28 showed traces of E. Coli from a pond during a dry weather sample. The city is currently looking into this. There are many birds in the area, and the water drains slowly. These issues may contribute to the problem. Other sites of concern this period were numbers 1, 2, and 11. These sites had higher values than typical. Site 1 had a peak E. Coli result last September 2010 and was down about half in spring. During major flooding that occurred in August 2010, a sanitary line broke in the hood arroyo. The issue was immediately fixed and the site cleaned, but it is believed that some residue contributed to the higher number. Also, a septic leak upstream of this area was fixed and the area cleaned.  Selenium and Mercury – It was suggested by AES that The City Of Farmington add the analysis of these two metals in Year 3 as potential contaminants of concern for T&E fish species in the San Juan River. AES has recommended running this analysis at least one more time in an effort to develop a better sense of the possible concentrations. The city did not see any samples that showed unusually high concentrations in these metals during year 4. Sampling continues to be more or less varied. Samples showed some new concerns for E. Coli that will need investigated further. In some cases though, these results were only high in one of the two sampling dates. It is difficult to find sources when they are not consistent in their presence. The varied results are not unusual for very arid climates where rainfall that produces runoff can be rare for extended periods of time. In many cases, sampling is taken at the first rainfall of the season that produces runoff. This produces results that may be high because any chemicals or metals that have found their way into the soil have built up during the dry times of little or no precipitation. Almost every sample that is collected could be seen as a first flush of the system. Then at times this is not the case and significant amounts of rain during August or September may result in much lower values since regular flow has moved minerals and nutrients in a more typical fashion. Site 22 was added, as has been discusses, to aid in locating high values of E. Coli in the Glade arroyo. The pond was sampled, and though it did show E. Coli, it is not believed this was high enough to be the only source of contamination, nor does it automatically mean that the source is the pond. The city would like to sample some key locations upstream and of this pond to help isolate the problem. The city has continued to use the Code Compliance Hotline to locate areas where illicit connection may be located. See section 3.3.6 for issues found and solved. One of the locations where a septic leak was fixed was on the Hood Arroyo north of the sampling location 1. This may have assisted in the better sampling results in April of 2011 compared to those found in September 2010. All of the code compliance calls in regards to illicit connections were septic leaks. Several of these were in locations that are upstream of sampling locations such as in site 1. Since the baseline sampling event in February 2007, the City of Farmington has swept the paved surfaces at the MOC each year (see Table 6-2). In addition, based on the first year sampling results and evaluation, the City of Farmington plans to continue to take the following actions: A. Monitor sampling results and revise sampling and dry weather inspection locations accordingly. After evaluation, if sampling values are found to be consistently above benchmark values, sampling will be strategically revised to locate the source of the problem. B. Continue with dry weather inspections at representative sampling locations. If flowing water is observed during a dry weather inspection, collect a sample for analysis of fecal coliform. ---PAGE BREAK--- 10/01/11 MS4 Annual Report Page 29 C. Continue with the evaluation of MOC operations, good housekeeping measures, and site structural BMPs; D. Gather more data about irrigation ditches and ditch returns; and E. Continue working with the San Juan Watershed Group to find opportunities to locate and solve stormwater quality issues. 3.3.2. Dry Weather Outfall Inspections Dry weather inspections were conducted and documented periodically throughout the reporting period. Inspection reports are on file at the City of Farmington and can be viewed upon request. The City will continue to conduct dry weather sampling at representative outfalls during the next reporting period to help identify potential illicit discharges. If flowing water is observed during a dry weather inspection, a sample will be collected for analysis of fecal coliform. The dry weather sampling helps the City identify possible sources of contamination in several ways. For one, it is an excellent way in which to find illicit connections when running water is observed. When there is no running water, inspectors look for other signs such as standing water, or the color or odor in the area. As discussed, site 22 was added to the dry sampling locations this reporting cycle in order to isolate possible source of contamination in the Farmington Glade. The city plans on adding more temporary sites to further identify these sources in the Glade Arroyo as well as in other locations. As is usual in the dry sampling reports, rust was found on deteriorating metal culverts in outfall locations. The city has for many years now used HDPE in the majority of culvert situations. Metal pipe is rarely, if ever, selected by the city. In this way, the city has replaced many of the metal pipes and will continue to replace them over time as necessary. The high alkalinity in Farmington’s soils makes metal piping a poor design choice in terms of contaminants and longevity of the pipe to perform long term. A dry weather result at one of the MOC outfalls showed some oil sheen. When city staff went to investigated, this sheen was no longer present. It is believed that the proposed actions to be taken at the MOC will aid in this issue. The city electric department is planning the constriction of storage facilities to house old transformers and equipment. See Section 6 for more information. 3.3.3. Camera Inspection and Cleaning Program In January of 2008, the City of Farmington contracted with a third party to implement a camera inspection and cleaning program. The total length inspected and cleaned during this reporting period is shown in Table 3-4. Table 3-4 Camera Inspection and Cleaning (July 2010 – June 2011) Sewer Type Video Inspection feet (miles) Cleaning feet (miles) Storm Sewer 4,470 ft. (0.85 mi.) 15,000 ft. (2.84 mi.)

Illicit Discharge Ordinance The City of Farmington is currently working to establish an illicit discharge ordinance. The new ordinance has still not undergone evaluation by Council for approval. It has been revised following the EPA’s suggested models. The legal department is assuring that the language used and structure of the ordinance is enforceable and meets our expectations. The ordinance is awaiting further revisions and approval. The new ordinance was not completed this cycle, but the City expects to take the new ordinance to Council for approval in year 5. 3.3.5. Storm Drain System Map and Master Drainage Study The City of Farmington has hired HDR Engineering, Inc. to develop a master drainage study. The project includes development of a field-verified and updated storm drain map and geographic information system (GIS) database as well as hydraulic modeling and analyses of the storm drainage collection system. It was estimated that the project would include roughly 100,000 lineal feet of pipe for analysis as well as the major arroyos in the city. It was found that the initial estimate was far below the actual feet of storm pipe in the city. It has since been determined that the number was closer to 250,000 lineal feet. This inconsistency, along with unforeseen difficulties in collecting all necessary data have delayed and extended the project completion. It is now expected that completion will be closer to early 2012, most likely in the spring. The city has collected nearly all necessary data and HDR is currently in the phase of analyzing that information and requesting any missing or inconsistent data. 3.3.6. Code Compliance Hotline The City has code compliance officers and a code compliance hotline to record and investigate illicit discharge complaints. During this reporting period 7 complaints were received in regards to illicit discharges. The types of complaints received during each month are summarized in Table 3-6. Each complaint was investigated by the City. Of the 7 total complaints, 2 complaints were not substantiated, and 6 were illicit discharges. Illicit discharges were each resolved. Table 3-5 Illicit Discharge Complaints Investigated (July 2010 – June 2012) Description Jul - Sept Oct - Dec Jan – Mar Apr - June Totals No Issue Found 1 0 0 5 1 Potable Water Leak 0 Swimming Pool 0 Landscape Irrigation 0 Air Conditioning Condensate 0 Total Allowable Discharges 0 0 0 0 0 Sanitary Sewer Leak 0 Irrigation Ditch Overflow 0 Septic System Leak 1 5 6 Restaurant Grease Leak/Dumping Gray Water Leak 0 ---PAGE BREAK--- 10/01/11 MS4 Annual Report Page 31 Description Jul - Sept Oct - Dec Jan – Mar Apr - June Totals Oil Dumping/Spill 0 Other Dumping/Spill 0 Total Illicit Discharges 0 0 1 5 6 Total Complaints 1 0 1 5 7 The city continues to find and address serious septic leak issues. While these are clearly not desired, the city is pleased to be slowly finding and correcting many of these serious groundwater issues that plague our streams and rivers. One of these issues solved was upstream of sampling site 1, and believed to have helped substantially with the lowering of E. Coli. Sampling taken before the fixed leak in September showed much higher presence of E. Coli than those taken in the Spring. Once any of these leaks is reported, the city takes immediate action to block off any surface flow and ensure that contaminants do not reach any storm system, natural or man-made. The resident is then given 24 hours to correct the situation. The site is properly cleaned and wastes disposed of. The City’s hazmat team has recently won a state award for its work in this area and works hard to remediate any spills or other contaminants during code compliance calls. 3.4. Activities Planned for the Next Reporting Cycle In the next reporting period, the City of Farmington plans to continue to perform stormwater and dry weather sampling at the representative outfall locations. The City will also continue to evaluate sample results in an effort to identify and address illicit discharges. The city will pass the new illicit discharge ordinance this year and continue to camera and clean storm drains. The City will complete the Master Drainage study. A summary of the planned goals and activities for the next reporting period is contained in Table 3-6. 3.5. Proposed Changes Proposed changes to the IDDE program goals are provided in Table 3-6. 3.6. Permit Obligations The City of Farmington does not rely on another government entity to satisfy permit obligations. 3.7. Inspections and Formal Enforcement Actions The code compliance team inspected 7 complaints of illicit discharge reports. 6 of the complaints were deemed illicit discharges and were each addressed and resolved. 3.8. Public Access, Review, and Comment Provisions Under the permit, the MS4 Annual Report is due October 1st of each year for the previous reporting period. The permit also requires a public comment period for at least thirty (30) days prior to the submission of the annual report. The City of Farmington met these requirements as described in the Public Meetings and Comment Periods paragraph of Section 1.3.1. No comments were made by the public prior to submittal.

In 2011, the coordinator attended the MS4 conference where classes were held on construction bmp’s. The MS4 coordinator continues to participate in web trainings hosted by the EPA and pass this information on to engineering and inspection staff. The City also plans to send the MS4 coordinator the annual MS4 conference to be held in 2013. 4.3.3. Stormwater Program Staffing Ryan Gladden P.E., an engineer employed by the City, has been the acting MS4 coordinator since February, 2009. There is currently no full time MS4 staff, and budgetary constraints have been greatly hindered the City’s ability to fill vacancies and open new positions. ---PAGE BREAK--- 10/01/11 MS4 Annual Report Page 38 4.3.4. Stormwater Construction Guidance The City of Farmington provided the following construction BMP guidance during this reporting period: ▪ BMP Guidance. The City’s website is frequently reviewed to ensure the most current information. This section continues to be updated and contains information on the SWMP as well as links to the USEPA’s National Menu of BMPs and guidance. http://www.fmtn.org/city_government/public_works/stormwater_management.ht ml. ▪ Technical Specifications. The construction standards were reviewed for relevant information in 2012. No significant changes were made to the BMP and erosion control section. The guide is posted on the City’s website and was made available at the Building Permit and Inspection Counter. Online address: http://www.fmtn.org/city_government/public_works/informational_documents.html ▪ Brochures. The City of Farmington continues to make the following brochures available at the Community Development and Building Inspection desk as well as on the internet: - Builder’s Stormwater Quick Reference Guide. This brochure was developed in March of 2008 by the City of Farmington and targets the construction industry and provides information on stormwater permit requirements, BMPs, the difference between erosion control and sediment control, and helpful BMP and resources. (Brochure is contained in Appendix - How Do I get Stormwater Permit Coverage for My Construction Site? A Construction Site Operator’s Guide to EPA’s Stormwater Permit Program, USEPA brochure (EPA 833-F-04-002, Sept 2007). - Reducing Stormwater Costs through Low Impact Development (LID) Strategies and Practices.

City of Farmington staff members actively participate with the local NSPE chapter, which meets once ---PAGE BREAK--- 10/01/11 MS4 Annual Report Page 39 during lunch with an invited speaker. The group is always looking for speakers with interests in water quality and erosion control. 4.4. Activities Planned for the Next Reporting Cycle The City will continue to review BMPs and training opportunities to determine if additional training or BMP updates are needed. The stormwater activities planned for the next reporting cycle are summarized in Table 4-2. 4.5. Proposed Changes There are no proposed changes from last report. See Table 4-2 4.6. Permit Obligations The City of Farmington does not rely on another government entity to submit information necessary to satisfy permit obligations; however, the City of Farmington does cooperate with other local organizations to achieve some SWMP Plan goals. For example, the City of Farmington works with the San Juan Homebuilders Association and San Juan College to provide information and updates to local builders and developers. 4.7. Inspections and Formal Enforcement Actions Under the City’s current grading ordinance, plan reviews are required for sites that disturb two or more acres. During construction, builders and developers are required to keep drainage onsite. If a drainage issue arises, building or construction inspectors and engineering staff review the issue and determine the appropriate resolution. If the issue is not resolved, city inspectors can stop construction at the site until the issues are resolved. The Construction Site Stormwater Runoff Control program is developing. It focuses on updating ordinances, training staff, acquiring resources, and educating local developers and builders. 4.8. Public Access, Review, and Comment Provisions Under the permit, the MS4 Annual Report is due October 1st of each year for the previous reporting period. The permit also requires a public comment period for at least thirty (30) days prior to the submission of the annual report. The comment period began Sept. 5th, which is less than the 30 days.

Stormwater Construction Education & Outreach The City of Farmington promoted several stormwater educational activities during this reporting period. Promotions are summarized below. ▪ Informational Booths. The City of Farmington hosted a booth on March 3rd and 4th of 2012, at the San Juan County Home Builders Association’s 18th Annual Home Improvement & Building Expo. The two-day event attracted local developers, builders, contractors, vendors, and residents interested in home improvements. The City’s booth contained stormwater educational information for the residential community and the construction industry. ▪ Educational Materials. The City of Farmington provided BMP guidance and technical specifications as well as informational brochures. See preceding section Stormwater Construction Guidance for more detail. ▪ Professional Associations. o National Society of Professional Engineers (NSPE). City of Farmington staff members actively participate with the local NSPE chapter, which meets once during lunch with an invited speaker. Two City staff members are currently officers in the local chapter and have helped to invite speakers whose topics are stormwater related. ▪ City Helpline – The City of Farmington’s Engineering Department is always ready to assist Contractors in the guidance of construction BMP’s. The engineering department frequently fields calls from contractors/builders for guidance. 5.3.5. Master Drainage Study The City of Farmington has hired HDR Engineering, Inc. to develop a master drainage study. The work includes development of a field-verified and updated storm drain map and geographic information system (GIS) database as well as hydraulic modeling and analyses of the storm drainage collection system. It is fully expected that the Master Drainage Study will reach completion this reporting cycle, most likely in the early part of 2012. 5.4. Activities Planned for the Next Reporting Cycle In the next reporting period, the City will continue work on reviewing existing ordinances to ensure they comply with MS4 requirements. The City will also continue to review BMPs and training opportunities to determine if additional training or BMP updates are needed. The stormwater activities planned for the next reporting period are summarized in Table 5-1. ---PAGE BREAK--- 10/01/11 MS4 Annual Report Page 45 5.5. Proposed Changes The proposed changes for the Post-Construction Stormwater Management in New Development and Redevelopment goals are summarized in Table 5-1. The post-construction map/guide has been designed as a web map. The map currently shows several locations within the city that represent successful BMP’s. The viewer can select a BMP site and read a description of that BMP, what it is used for, and see a photo of its implementation. 5.6. Permit Obligations The City of Farmington does not rely on another government entity to submit information necessary to satisfy permit obligations; however, the City of Farmington does cooperate with other local organizations to achieve some SWMP goals. For example, the City of Farmington works with the San Juan Homebuilders Association and San Juan College to provide information and updates to local builders and developers. 5.7. Inspections and Formal Enforcement Actions Under the City’s current plan review process, plan reviews are required for sites that disturb two or more acres and developers are required to build post-construction controls that maintain historic drainage levels. The Post-Construction Stormwater Management in New Development and Redevelopment program is progressing and still developing. It focuses on updating ordinances, training staff, acquiring resources, and educating local developers and builders. 5.8. Public Access, Review, and Comment Provisions Under the permit, the MS4 Annual Report is due October 1st of each year for the previous reporting period. The permit also requires a public comment period for at least thirty (30) days prior to the submission of the annual report. The City of Farmington met these requirements as described in the Public Meetings and Comment Periods paragraph of Section 1.3.1. No comments were made by the public prior to submittal. The Annual Report was finalized and submitted to the permitting authority by October 1, 2012. ---PAGE BREAK--- 10/01/11 MS4 Annual Report Page 46 Table 5-1 Post-Construction Stormwater Management in New Development and Redevelopment Program Area Status for Year 5, Planned Activities for Year 6, and Proposed Goal Changes Description of Goal Department/Personnel Responsible for Implementation Month in SWMP1 Year of Permit in SWMP1 GOAL #1 – Year 5 of the Permit 1.

POLLUTION PREVENTION/GOOD HOUSEKEEPING FOR MUNICIPAL OPERATIONS 6.1. Implementation Status Table 6-2contains the status of the Pollution Prevention/Good Housekeeping for Municipal Operations Program goals planned during 2007 as well as the status on any goals where work has already begun in preparation for future deliverables. 6.2. Overall Compliance with Permit Conditions The measurable goals for the Pollution Prevention/Good Housekeeping for Municipal Operations program area include maintenance activities to keep stormwater drain inlets and lines free of debris and reduce dust generation from unpaved roads. Goals also focus attention on the MOC to identify pollution prevention and education opportunities that will improve the quality of stormwater leaving the facility. 6.3. Results of Information Collected and Analyzed During the Reporting Period The following sections provide information collected during this reporting period. 6.3.1. Street Sweeping The City’s street sweeping program sweeps paved city surfaces and properly disposes of collected debris. The sweeping program is fairly consistent and is not expected to deviate much from year to year. During this reporting period, the street sweeping program swept roughly 18,700 miles of paved surfaces. The total mileage swept includes regular sweeping at City parking lots, as shown in Table 6-1 Table 6-1 Street Sweeping at Municipal Parking Lots City Parking Lots Number of Times Swept During Reporting Period City Hall and City Annex 12 times City Police Department 12 times City Courthouse 12 times Downtown City Parking Lots 12 times MOC Parking Lots 10 times The table shows the routine sweeping that occurs once a month. Along with those sweepings, emergency sweepings were also performed over many streets within the City limits. In August 2010, wide spread flooding occurred over much of the city depositing sand and debris over streets and roads. City workers spent weeks cleaning and sweeping a good majority of many of the city’s streets. 6.3.2. Storm Drain Cleaning In January of 2008, the City of Farmington contracted with a third party to implement a video inspection and cleaning program. The total length of main lines inspected and cleaned is provided in Section 3 Illicit Discharge Detection and Elimination. ---PAGE BREAK--- 10/01/11 MS4 Annual Report Page 50 The City’s Street Crew also cleans storm drain inlets and grates as needed. During flooding in August 2010, many inlets were plugged with sediment and debri. The city’s streets crew worked hard to clean these systems as well as the arroyos. 6.3.3. Dust Abatement Applications to Unpaved Roads Dust abatement applications were applied as needed to major unpaved roads within the City limits. There are approximately 32 miles of unpaved roads in Farmington. During the reporting period, there were approximately five applications for each unpaved road. 6.3.4. Municipal Operations Center Sampling and Operations Review The review from previous reports has been left in for historical information. New comments have been added at the end of this section 6.3.4. Operations at the City of Farmington’s Municipal Operations Center (MOC) are covered under the City’s MS4 Phase II permit. Baseline samples collected at MOC outfalls in February 2007 indicated elevated concentrations of specific conductivity and COD. (Sampling results are discussed in Section 3 Illicit Discharge Detection and Elimination and provided in Appendix As a result, the City began to review MOC operations and structural BMPs. The City of Farmington conducted an onsite visit at the MOC in February of 2007 to view operations areas and identify housekeeping improvements. Based on the visit, improvement opportunities were identified, and the following actions were taken: ▪ Swept paved surfaces and continued sweeping throughout the reporting period, ▪ Cleaned up and organized material storage areas, ▪ Removed trash from the yard and storm drain outlet areas, and ▪ Relocated several items to covered storage areas. Sampling results from MOC outfalls in August of 2007 showed improvements in specific conductance and COD but showed elevated concentrations of Aluminum and TSS. Two more site visits were was conducted on November 2, 2007 and January 16, 2008. The team reviewed onsite stormwater controls and discussed improvements for a planned parking lot upgrade project at the MOC. Approximately 1,660 feet of storm drain lines at the MOC were inspected via video camera in January and February 2008. Improvements were then added to the design package for the MOC parking lot upgrade project, which will be completed incrementally over the next few years as budget is available. The MOC parking lot redesign will improve overall site drainage, inlet designs, and add a berm or curb and gutter around the facility’s perimeter as a secondary control for stormwater management. The city will continue to focus on the importance of good housekeeping at the MOC. Such results show improvements are taking place and the practices and goals set forth within the SWMP are having a positive effect. A planned installation of a salt storage facility at the MOC is still planned for future construction. The storage facility is expected to further decrease potential pollution. It is anticipated that the facility will allow for the gathering of potential contaminants that can be extracted and prevented from reaching the river. ---PAGE BREAK--- 10/01/11 MS4 Annual Report Page 51 Year 4 contaminant results were fairly consistent with the previous year. The majority of contaminants are either below or near benchmark values. The high values in iron and aluminum are consistent with many of the other sites across the city limits during the same periods and not significantly higher. Iron and aluminum were high across almost every sampled location. They are naturally occurring contaminants within the arid southwest. Other planned improvements at the MOC site deal with more storage facilities for old and large equipment. Currently, the city electric department is planning the construction of a facility to house old transformers as well as large construction equipment. These improvements are expected to lower the metal contaminants as well as those relating to oil and suspended solids. 6.3.5. Stormwater Training for Municipal Employees Employee training was not completed in year 4 though it was advanced. A slideshow and video have been put together to explain the necessity as well as the methods of good house keeping. The curriculum was not approved this year, but the City is hopeful to present the material for approval this coming year. Activities Planned for the Next Reporting Cycle In the next reporting period, the City will continue to perform outfall sampling and implement current BMPs, such as dust abatement and drain cleaning activities. In addition, the City will focus on modifying operational procedures and providing stormwater training in municipal operations areas. 6.4. Proposed Changes Proposed changes to this program area are summarized in Table 6-2. 6.5. Permit Obligations The City of Farmington does not rely on another government entity to satisfy permit obligations. 6.6. Inspections and Formal Enforcement Actions Three site visits were conducted at the MOC. The first site visit was performed in February 2007; the second was performed in November of 2007; and the third was performed in January of 2008. The City is using the information gathered to develop a plan and budget to improve stormwater site controls, municipal procedures, and employee training. The City’s Airport and Power Plant have reviewed their MSGP requirements and are at this time working to meet goals. They perform annual training on accidental spills prevents among other employee outreach. Additional inspections and reviews will be conducted at other City facilities covered under the MS4 permit to identify pollution prevention and good housekeeping opportunities. 6.7. Public Access, Review, and Comment Provisions Under the permit, the MS4 Annual Report is due October 1st of each year for the previous reporting period. The permit also requires a public comment period for at least thirty (30) days prior to the submission of the annual report. The City of Farmington met these requirements as described in the Public Meetings and Comment Periods paragraph of Section 1.3.1. No comments were made by the public prior to submittal.

The following notes pertain to Table C-1.  Benchmarks. The EPA benchmark values assist in evaluating stormwater impacts; however, they are not enforceable standards.  Shading. The following shades were used in table cells to highlight results higher than benchmark values. o Light Gold – Greater than benchmark value, but less than two times the benchmark value. o Dark Orange – More than two times greater than the benchmark value.  Acronyms: o COD – Chemical Oxygen Demand o E. coli – Fecal Coliform o NA – Not Analyzed o NE – Not Established o NM – Not Measured o NO3/NO2 – Nitrate/Nitrite o NS – Not Sampled o TSS – Total Suspended Solids o TKN – Total Kjeldahl Nitrogen  Normal Background Conditions: o Concentrations of TSS are indicative of soil sediments present in stormwater, and elevated TSS concentrations are typical in the arid Southwest. o Specific conductivity is generally found to be a good measure of the concentration of total dissolved solids (TDS) and salinity. Elements whose ionic forms contribute the most to these measures include: calcium (Ca2+), magnesium (Mg2+), sodium potassium bicarbonate (HCO3-), sulfate (SO42-), and chloride Elevated levels of specific conductivity are typical in the arid Southwest.  Precipitation Levels: o February 8, 2007 – 0 inches (significant snow melt) o July 11 and 12, 2007 – 0.15 inches o August 1 and 2, 2007 – 0.06 inches o August 27 and 28, 2007 – 0.23 inches o December 7 and 8, 2007 – 0.34 inches o March 17 and 18, 2008 – 0.06 inches o May 16, 2008 – 0.21 inches o September 8, 2008 – 0.24 inches o March 13, 2009 – 0.17 inches o April 2 – Dry Sampling o May 21, 2009 – Dry Weather Inspection o June 26, 2009 - 0.18 inches o Jan 19, 2010 – 0.23 inches o March 10, 2010 – 0.16 inches o September 22, 2010 – 0.49 inches o April 7, 2011 – 0.15 inches
