BACKGROUND The NPDES Program requires that the City implement a comprehensive SWMP that complies with the requirements outlined in the City's NPDES Phase II permit which became effective February 16, 2007 and was reissued August 1, 2012. On August 1, 2013 an updated NPDES Phase II permit will be in effect. The conditions of the existing and updated permit require that the City develop a SWMP and submit annual reports to the Department of Ecology (DOE) outlining our progress in meeting permit requirements by March 31 of each year. The SWMP document commits the City to activities which have staffing, training, procedural, and documentation requirements that the City must follow. The SWMP is updated annually to reflect any required changes to our program and to provide greater detail as various programs are fully developed. Once submitted to the DOE, this plan will be used to determine whether permit obligations are being met. DISCUSSION City staff completed the 2012 Annual Report, which reflects activities completed by the City in 2012. In addition, staff also updated the 2012 SWMP to reflect permit requirements for 2013. All 2013 updates are printed in blue for reference. The 2012 Annual Report must be signed by the City Administrator and both documents must be sent to the DOE by the reporting deadline of March 31, 2013. RECOMMENDATION Information only.

CONCLUSION 18 City of Tukwila Stormwater Management Program 2 of 18 March, 2013 40 1. INTRODUCTION The National Pollutant Discharge Elimination System (NPDES) permit program is a requirement of the federal Clean Water Act. 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). This document was prepared by the City of Tukwila to meet the requirements for a Stormwater Management Program (SWMP) as required by the NPDES Phase II Permit. The SWMP was developed to outline the reduction of pollutant discharges from the City's Municipal Separate Storm Sewer System (MS4). The Permit allows discharge of stormwater runoff from municipal drainage systems into the state's water bodies (i.e., streams, rivers, lakes, wetlands, etc.) as long as municipalities implement programs to protect water quality by reducing the discharge of "non -point source" pollutants to the "maximum extent practicable" (MEP). In addition, the City must meet "all known and reasonable treatment" (AKART) through application of Permit specified "best management practices" (BMPs). The practices specified in the Permit are collectively referred to as the SWMP and grouped under the following program components: o Public Education and Outreach o Public Involvement and Participation o Illicit Discharge Detection and Elimination o Controlling Runoff from New Development, Redevelopment and Construction Sites o Pollution Prevention and Operation and Maintenance for Municipal Operations The Permit requires that the City report annually (by March 31 of each year) on the SWMP implementation from the prior year. The Permit also requires submittal of documentation that describes proposed program activities for the coming year. As of December 31, 2012, the City met the Permit requirements. City of Tukwila Stormwater Management Program 3 of 18 March, 2013 41 2. NPDES PHASE II PROGRAM COMPONENTS Tukwila is defined as a Phase II community by DOE and, therefore, mandated to comply with the requirements of the Phase II National Pollution Discharge Elimination System (NPDES) Stormwater Permit. Phase II communities are those that: o Own and operate a storm drain system o Discharge to surface waters of the state o Are located in urbanized areas o Have a population of more than 1,000 As such, Phase II refers to permits that cover the state's second most populated areas with Phase I permits having the most populated areas. As a Phase II community, Tukwila applied for and was issued a NPDES Phase II Stormwater Permit January 17, 2007, modified June 17, 2009 and expired February 15, 2012. DOE extended the Permit for a period of one year, with no modifications in July 2012. The Permit will be replaced with an updated NPDES Phase II Stormwater Permit August 1, 2013 which will expire July 31, 2018. As stated, the major program components listed in the Permit are as follows: o Public Education and Outreach o Public Involvement and Participation o Illicit Discharge Detection and Elimination o Controlling Runoff from New Development, Redevelopment and Construction Sites o Pollution Prevention and Operation and Maintenance for Municipal Operations The following sections describe each of the program components and how the City is currently addressing each requirement and the City's future planned activities. In general, the City of Tukwila is currently performing all required NPDES Phase II Permit activities and has programs in place to address the updated Permit requirements. 2.1 PUBLIC EDUCATION AND OUTREACH 2.1.1 Permit Requirements Section S5.C.1 of the Phase II permit requires that the City provide an educational and outreach program for the area served by its MS4 no later than 2/15/2009. The purpose of this program is to reduce or eliminate behaviors and practices that cause or contribute to adverse stormwater impacts. The educational program will target audiences including: the general public, businesses and industries, elected officials, policy makers, planning staff, engineers, maintenance staff, and other City employees. Records of public education and outreach activities including measurements of understanding and adoption of targeted behaviors need to be tracked and maintained throughout the Permit's duration. City of Tukwila Stormwater Management Program 4 of 18 March, 2013 42 2.1.2 Current Activities The City currently has an active public educational and outreach program that uses a variety of approaches to inform residents and businesses about stormwater related pollution - prevention activities. The City uses many resources for educational information such as DOE's Hazardous Waste and Toxics Reduction Program, Environmental Protection Agency's Region 10 Pacific Northwest, King County's Department of Natural Resources and Parks, Water Resource Inventory Area 9, and local environmental organizations. The City's current educational activities consist of the following: 1. Water Course Signing: o The City has placed and maintains signs at all stream crossings to educate pedestrians and motorists of the location of local streams. Signs identify the stream name and read "This Stream Is In Your Care." 2. Catch Basin Labeling: o All new public or private catch basins are required by City standards to be labeled with either torch down pavement decal stating "Dump No Waste - Drains to Stream," or glue down metal marker stating "No Dumping Drains to River." o All paving projects, both private and public, that pave around an existing catch basin are required to label all catch basins with the torch down decal or metal pavement markers. o Currently, the City's Maintenance Department has installed over 3,000 glue down metal pavement markers that states, "No Dumping — Drains to River ". o All inlet castings are required by City standards to be labeled "Outfall to Stream - Dump No Pollutants. 3. City Newsletter and Newspaper: The City of Tukwila publishes the Hazelnut (newsletter) 3 times a year and a monthly Tukwila Reporter (newspaper) that includes articles concerning stormwater related topics. Typical topics covered include: o Car Washing o Illegal dumping of materials in storm drains o Landscape chemicals o Proper disposal and methods of reducing household hazardous wastes o Notices for public participation in the Surface Water Management Program o NPDES Permit updates 4. Water Quality Brochures: The Public Works Department has brochures and handout materials available and on display that include the following topics: o Spill Kit Pilot Program, Stormwater Education for Businesses o Puget Sound Shoreline Stewardship Guidebook o Disposing of Hazardous Wastes Information Card o Hazardous Waste Directory o Ecology - Shoptalk, Spills -Who Do You Call? City of Tukwila Stormwater Management Program 5 of 18 March, 2013 43 o Antifreeze Recycling o EPA's Information Sheet Regarding Oil/Water Separators o Automotive and the Do It Yourselfer o Puget Sound Shoreline Stewardship Guidebook o Ecology — Five Steps to Natural Yard Care o Pet Waste Brochures that specifically address Stormwater Pollution Prevention o Carpet cleaning o Rain Garden Handbook for Western Washington Homeowners o Concrete Washout Area Best Management Practice o Your Septic System 5. User Surveys: The City conducts annual surveys to a targeted audience that measures the public's understanding of surface water related topics. For 2012, the City conducted a phone survey titled "2012 Assessment of Citizen Understanding and Adoption of Targeted Stormwater Behaviors ". The goal was to measure the public's knowledge and practices regarding stormwater in the City of Tukwila. The results of this survey and previous surveys can be found on the City's NPDES webpage: www.tukwilawa.gov /pubwks /npdes.html information obtained from the survey will be used to guide future education and outreach programs. 6. Regional Outreach: Participate in the King County's regional outreach forum, STORM, on an ongoing basis to share ideas on public education efforts. 7. The City uses its inspection program for an opportunity to provide stormwater education to facility operators giving them a better understanding of the purpose of our Phase II Permit. 8. The City has initiated an elementary school stormwater educational series that involves students from Tukwila Elementary School's 5th grade science classes. 9. Led by Boeing Employees Credit Union (BECU), the City partnered with Forterra, CBR and Tukwila businesses, in a "Restore the Duwamish Shoreline Challenge" campaign aimed at restoring the riverbanks of the Duwamish River. Funding provided by BECU, King Conservation District and CBR. The City provided technical support, equipment and plantings. 10. The City continued with its Cottage Creek Restoration project at City Hall. Public participation, City officials and staff helped with the success of the project.
