TIC 2017-03-28 Item 2A - Discussion - NPDES Program: 2016 Annual Report / 2017 Stormwater Management Program Plan
City of Tukwila Allan Ekberg, Mayor Public Works Department - Bob Giberson, Director INFORMATIONAL MEMORANDUM TO: Transportation and Infrastructure Committe FROM: Bob Giberson, Public Works Director ° &-`' BY: Greg Villanueva, NPDES Coordinator CC: Mayor Ekberg DATE: March 24, 2017 SUBJECT: NPDES Program Project No. 99341210 2016 Annual Report and 2017 Stormwater Management Program Plan ISSUE Review the City's 2016 National Pollutant Discharge Elimination System (NPDES) Annual Report and 2017 Stormwater Management Program (SWMP) Plan. BACKGROUND The NPDES Program requires that the City implement a comprehensive SWMP Plan that complies with the requirements outlined in the City's current NPDES Phase II permit. The permit requires that the City develop a SWMP Plan and submit annual reports to the Department of Ecology (DOE) outlining our progress in meeting permit requirements by March 31st of each year. The SWMP Plan document describes proposed activities for the current year training, procedural, and documentation requirements that the City must follow. The SWMP Plan is updated annually to reflect any required changes to our program and to provide greater detail as various programs are fully developed. Once the SWMP Plan is submitted to the DOE, it will be used to determine whether permit obligations are being met. DISCUSSION City staff completed the 2016 Annual Report, which reflects activities completed by the City in 2016. In addition, staff also updated the 2016 SWMP Plan to reflect permit requirements for 2017. All 2017 updates are printed in blue for reference. The 2016 Annual Report must be signed by the City Administrator and both documents electronically submitted to the DOE by the reporting deadline of March 31, 2017. RECOMMENDATION Information only.

Topics included Low Impact Development and Discharging Carpet Wastewater to a Storm Drain is Illegal. • The City conducted a Stormwater Survey and Assessment in 2015 which measured the public's understanding of stormwater pollution and its effects on our creeks, river, and the Puget Sound. The City used the findings from 2015 and in 2016 targeted City residents and businesses by informing them of a priority 1 issue regarding impervious pavement, sediment, automotive fluid leaks, car wash soapy water runoff and pet waste. • In 2016, the City posted LID Code update findings, draft amendments to our City Development Codes and draft amendments to our City Infrastructure Design and construction Standards. The City also posted the 2016 King County Surface Water D4esign Manual and 2016 King County Stormwater Pollution Prevention Manual. The City's NPDES web page 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. • The City 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. • The City provided a SWMP booth at the annual Backyard Wildlife Festival. 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 and Antifreeze Recycling. • The City uses government Channel 21 which was implemented as a tool to provide updates and information.

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 2016 the City used the results of the 2015 survey which the following outcomes were identified: 1. Determined the overall public perception of the quality of surface water in Tukwila and compared it to the previous year' rating. 2. Identified Priority 1, priority 2 and Priority 3 issues for Tukwila residents. This helps to determine what perceptions, behaviors, and practices need the most attention as well as provide direction for an educational outreach program. 3. Identified shifts and trends in Identified Priority 1, priority 2 and Priority 3 issues that occurred from previous years. 4. Identified Priority 1, priority 2 and Priority 3 issues for residents and property owners. The 2015 survey indicated there was a 20% drop in correct answers regarding the true or false statement "carpet shampoo wastewater can be safely added to a stormwater drain ". For this reason, the City chose to target the public and businesses by inserting a Discharging Carpet Wastewater to a Storm Drain is Illegal" information sheet into a surface water utility billing.

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 located 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 /phaseIIww /wwphiipermit.html Tukwila completed requirements of its initially issued NPDES Phase II Stormwater Permit which expired July 31, 2013. Tukwila applied to the Department of Ecology and was issued a new five -year term NPDES Phase II Stormwater Permit on August 1, 2012 with an effective date of August 1, 2013 and an expiration date of July 31, 2018. The Permit was then modified and reissued December 17, 2014 with an effective date of January 16, 2014 to further control the discharge of pollutants to protect surface water and ground water quality in Washington State 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. 22 NPDES PHASE II PROGRAM COMPONENTS The practices 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 201 Annual Report. 7.1 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 15th until the permit expiration date of July 31, 2018. 30 CONCLUSION On August 1, 2013, the City of Tukwila's new 5 -year term NPDES Phase II permit went into effect and was modified January 16, 2014. This Stormwater Management Program Plan has been prepared to demonstrate 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, 2018. LID and monitoring requirements are the significant changes to the new Permit. 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 if and 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.tukwilawa.gov/pubwks/npdes.html. The public is encouraged to participate in the development of the SWMP Plan.
