BACKGROUND The NPDES Program requires the City to implement a comprehensive SWMP Plan that complies with the requirements outlined in the City's NPDES Phase II Permit (five-year term). The City's NPDES Phase II Permit became effective August 1, 2013, was modified January 16, 2014 and on August 16, 2017 extended one year with a new expiration date of July 31, 2019. The Phase II Permit requires the City to develop a SWMP Plan and submit annual reports by March 31 of each year to the Department of Ecology (DOE) that outlines the City's progress in meeting permit requirements. The SWMP Plan forecasts activities that are relevant to the NPDES Phase II Permit which the City must follow. The SWMP Plan is updated annually to reflect any changes and timelines of the Permit and to provide greater detail as various components of the permit are developed. The Annual Report reflects the activities completed in the previous year. Once the 2018 SWMP Plan and 2017 Annual Report is submitted to DOE, it will be used to determine whether permit obligations are being met. ANALYSIS City staff has completed the 2017 Annual Report and updated the 2018 SWMP Plan. All updates in the SWMP Plan are printed in blue for reference. The 2017 Annual Report must be signed by the City Administrator and both documents electronically submitted to DOE by the reporting deadline of March 31, 2018 FISCAL IMPACT The program elements listed in the 2018 SWMP Plan required by the NPDES Phase II Permit have been budgeted and have no direct financial impact. RECOMMENDATION The 2017 Annual Report and 2018 SWMP Plan is information only.

The federal Environmental Protection Agency (EPA) has delegated permit authority to state environmental agencies. In Washington, the NPDES delegated permit authority is the Washington State Department of Ecology (DOE). The City of Tukwila prepared this document to meet the requirements for a Stormwater Management Program (SWMP) Plan as required by the NPDES Phase II Stormwater Permit issued to the City of Tukwila by DOE. The SWMP Plan was developed to reduce pollutant discharges from the City's Municipal Separate Storm Sewer System (MS4). Tukwila is defined as a Phase II community by DOE and, therefore, mandated to comply with the requirements of the NPDES Phase II Stormwater Permit. Phase II communities are those that: • Own and operate a storm drain system • Discharge to surface waters of the state • Are in urbanized areas • Have a population of more than 1,000 Municipalities with a population of over 100,000 (as of the 2010 census) have been designated as Phase I communities and must comply with DOE's Phase I NPDES Municipal Stormwater Permit. Tukwila's population is below the 100,000 threshold and must comply with the Phase II Municipal Stormwater Permit. Approximately 100 other municipalities in Washington must now comply with the Phase II Permit, as operators of small "municipal separate storm sewer systems" (MS4). Ecology's Phase II Permit is available on Ecology's website at: http://www. ecy. wa.gov/programs/wq/stormwater/municipal/phasellww/wwphiipermit.html Tukwila was first issued a Western Washington Phase II Municipal Stormwater Permit in January 17, 2007 (February 15, 2012 permit term), and June 17, 2009 Ecology modified the permit. August 1, 2012 the permit term was extended to July 31, 2013. A new five-year Permit term went into effect August 1, 2013 and was modified January 16, 2014. After careful consideration of many factors, Ecology extended the current 2013-2018 Permit term for one year. A new Western Washington Phase II Municipal Stormwater Permit will reissue on July 1, 2019 and become effective on August 1, 2019 and be in effect for five years. The Permit allows discharge of stormwater runoff from municipal drainage systems into the state's water bodies (i.e., streams, rivers, lakes, wetlands, etc.) if municipalities implement programs to protect water quality by reducing the discharge of "non -point source" pollutants to the "maximum extent practicable" (MEP). In addition, the City must meet "all known and reasonable treatment" (AKART) through application of Permit specified "best management practices" (BMPs). The majority of Tukwila's MS4 either drains to Riverton Creek, Southgate Creek, Gilliam Creek, Johnson Creek or directly to the Green/Duwamish River. The remaining areas infiltrate into the ground. 1 4 NPDES PHASE II PROGRAM COMPONENTS The BMPs specified in the Permit are collectively referred to as the SWMP Plan and grouped under the following program components: • Public Education and Outreach • Public Involvement and Participation • Illicit Discharge Detection and Elimination • Controlling Runoff from New Development, Redevelopment, and Construction Sites • Municipal Operation and Maintenance • Special condition, Total Maximum Daily Load Requirements • Special condition, Monitoring and Assessment The following sections describe requirements of each program component and the City's planned activities to meet the requirements.

COMPLIANCE WITH TOTAL MAXIMUM DAILY LOAD REQUIREMENTS The Permit (Special Condition Section S7) requirements: The Permit (Section S7) requirements apply if an applicable Total Maximum Daily Load (TMDL) is approved for stormwater discharges from MS4s owned or operated by the Permittee. Applicable TMDLs are TMDLs which have been approved by EPA on or before the issuance date of this Permit or prior to the date that Ecology issues coverage under this permit, whichever is later. A TMDL is a calculation of the maximum amount of a pollutant that a water body can receive and still safely meet water quality standards. The DOE determines the reduction of pollutant discharge needed to be compliant with water quality standards. 6.1 Activities • A TMDL has not been established for the City of Tukwila at this time, consequently no action needed. 7. MONITORING AND ASSESSMENT The Permit (Special Condition Section S8) requires the City to: • Notify DOE of its choice to independently conduct Status and Trends Monitoring and Effectiveness Studies or participate by paying annually into the Regional Stormwater Monitoring Program (RSMP) that will be conducted by DOE. • Pay into the RSMP to implement the Source Identification Information Repository (SIDR) element of the RSMP. • Track and Document additional monitoring conducted and summarize in the 2016 Annual Report. 7.1 Continuing and Current Activities • The City paid a fee of $4.444,00 into the RSMP to have DOE conduct the Status and Trends Monitoring. • The City paid a fee of $7,405.00 into the RSMP to have DOE conduct the Effectiveness Studies. • The City paid a fee of $687.00 into the RSMP to have DOE conduct the Source ID and Diagnostic Monitoring. The total fee of $12,536 is due each year by August 15t1' until the permit expiration date of July 31, 2019. 10 13 CONCLUSION The current Western Washington Phase Il Permit expires on July 31, 2018. DOE extended the current (2013-2018) Permit for one year. The Permit will reissue on July 1, 2019 and become effective on August 1, 2019. This Stormwater Management Program Plan has been prepared to demonstrate efforts and compliance with the requirements of this current NPDES Phase II Permit. This SWMP Plan will be a working document with updates annually until the Permit expires on July 31, 2019. The City's Public Education and Outreach Program is an extension of the previous permit term and will continue to grow with the planned activities. The City of Tukwila will continue to reach out and encourage public involvement and participation in the City's SWMP Plan with the existing notification process. The City's IDDE Program is in place, which includes a spill hotline, and will be reviewed periodically to ensure performance measures are met. The City adopted the 2016 KCSWDM, KCSPPM and revised its standards and codes to include LID and BMPs as the preferred method for development in December 2016, and uses it for controlling runoff from new development, redevelopment, and construction sites. The City of Tukwila's Operations & Maintenance (O&M) is very active in all areas of permit compliance. It should be noted; The 2016 KCSWDM & KCSPPM have new maintenance standards that O&M will follow. Coordination efforts will continue with neighboring jurisdictions and be reviewed to determine where improvements are needed to remove jurisdictional barriers. Total Maximum Daily Load requirements in Tukwila have not been determined by DOE to date. However, the City will prepare for this requirement when it comes due. The City chose to participate in the RSMP collective fund and have DOE administer and conduct the Monitoring and Assessment for this Permit term. Additional information on the City's NPDES program can be found online at http ://www. tukwi l awa. go v/pubwks/npdes.html.

For 2017 a Stormwater Word Search Puzzle were inserted into utility bill mailings and posted on the City's NPDES web page and flyers placed at strategic locations. Topics included Low Impact Development and managing stormwater. • Tukwila partnered with Puget Sound Starts Here campaign and purchased an 8 -page Seattle Times insert educating people on stormwater pollution which also included participating schools in Tukwila. • Tukwila conducted a Stormwater Survey and Assessment in 2017 which measured the public's understanding of stormwater pollution and its effects on our creeks, river, and the Puget Sound. The City will use the findings in 2018 and target City residents and businesses by informing them of a priority 1 & 2 issues regarding impervious pavement, sediment, pesticides, fertilizers, weed control chemicals, car wash soapy water runoff and infiltration trenches. • Posted on the City's web page the LID course training catalog, 2016 King County Surface Water Design Manual and 2016 King County Stormwater Pollution Prevention Manual. Also posted an Illicit Discharge Detection & Elimination video that is available in English and Spanish and a Lost and (Puget) Sound stormwater video directed at school aged children. • Provided an NPDES Inspection Van that included interactive stormwater testing at a City sponsored Touch a Truck event that is held annually. Interactive water sample testing was conducted with the public to promote water quality in Gilliam Creek, Riverton Creek, Southgate Creek, Johnson Creek, cottage Creek and the Green/Duwamish River.

Staff promoted low impact development by demonstrating how pervious concrete works and conducted a hands-on water sampling demonstration using a turbidity meter and pH test kits. Also, staff engaged with the children using a Child Passport Questionnaire regarding stormwater quality. • A variety of brochures are made available, and are handed out during residential and business storm drainage inspections on Low Impact Development, Protecting Washington's Waters from Stormwater Pollution, Local Recycling Center for Used Oil, Spills -Who do you call? Natural Lawn Care, Small Business Hazardous Waste Disposal and Good Business Practices for Carpet Cleaning & Wastewater Disposal. • Posted five Urban Watershed display boards at strategic locations along the Green/Duwamish River promoting major watershed issues. • Posted Puget Starts Here, FixCarLeaks.org, Free "No Leaks" Event Flyer. • Tukwila conducted a stormwater education and outreach presentation to a Tukwila Elementary 3rd Grade combined class of 60 students.

In addition, the research assesses Tukwila businesses stormwater practices and behaviors. The City uses the research for stormwater planning as well as educational outreach to improve the target audience's understanding of the stormwater impacts. For 2017 the City hired HR2 Research/Analytics to assess changes in the public's stormwater knowledge and related behavior from 2011, 2012 and 2013 to 2015 and the following residential outcomes were identified: 1. Priority 1 topics such as Low -Impact Development, pesticides, fertilizers, herbicides and car washing. Less than 50% gave the correct answers. 2. Priority 2 topics such as washing cars at home, disposal of latex paint, definition of an illicit discharge. Between 50-80% gave correct answers. 3. Priority 3 issues such as having your oil changed by an auto shop, the price of protecting our water ways from pollutants versus the cost of cleaning contaminated water. Over 80% gave correct answers. Commercial which included restaurants, property owners/managers and automotive companies the following priority 1 outcomes were identified: 1. Priority 1 topics such as internal wash water is not connected to the storm drainage, dumpster lids, disposal of cooking oil and grease, use of spill kits and lawn and moss care. Up to 80% gave correct responses. As many as 60% of questions had no response, likely do to lack of education. 25 26 2017 ILLICIT DISCHARGE, DETECTION & ELIMINATION Sheet 1 of 4 DATE DATE LOCATION RFA ILLICIT DISCHARGE ACTION TAKEN FINAL RECEIVED RESPONDED NAME ERTS 1/3/2017 1/3/2017 Amara Apt.
