BACKGROUND The NPDES Program requires that the City implement a comprehensive SWMP Plan that complies with the requirements outlined in the City's NPDES Phase II Permit. The City's NPDES Phase II Permit became effective August 1, 2013 and currently has an expiration date of July 31, 2019, A new NPDES Phase II permit will be issued on August 1, 2019 for a five-year term. The Phase II Permit requires the City submit an annual report and SWMP Plan by March 3151 of each year to the Department of Ecology (DOE)_ The annual report outlines the City's progress in meeting permit requirements. The SWMP Plan forecasts activities that are relevant to the NPDES Phase II Permit 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 Annual Report and the 2019 SWMP Plan are submitted to DOE, it will be used to determine whether permit obligations are being met. ANALYSIS City staff has completed the 2018 NPDES Annual Report and updated the 2019 SWMP Plan_ All updates to the SWMP Plan are printed in blue for reference. The 2018 NPDES Annual Report must be signed by the City Administrator and both documents electronically submitted to DOE by the reporting deadline of March 31, 2019.

The sampling was conducted in accord with the Stormwater Sampling and Analysis Plan, City Outfall to Boeing Z Line, PBS -March 16, 2016. Identification and visual observations of the stormwater sample point are presented below. A summary of the laboratory analysis results at the sample location is presented as Table 1 (attached), Rainfall amount on this day (24-hour period) totaled 0.88 inches (Source: Weather Underground — Seattle, Seattle Boeing Field (KBFI weather station)). Manhole 36-165: The sample point is a manhole that conveys runoff from East Marginal Way and is located just upstream of the former Boeing plant Z-line storm sewer (see Figure 1). PBS collected the sample from the channel at the bottom of Manhole 36-165 on January 11, 2018. There was some floating solids observed during the sample collection but no visible sheen. The analyzed sample indicated that levels of total suspended solids (26 milligrams per liter (mg/L)), copper (11.7 micrograms per liter (pg/L)), zinc (60,8 pg/L), pH (6.9), lead (5.39 pg/L) and polychlorinated biphenyls (PCBs) (<0.001 pg/L) were within the adopted benchmark stormwater guidance levels (Washington State Department of Ecology Storm water Sampling Manual A Guidance for the Industrial Stormwater General Permit dated December 2015), Turbidity (50 nephetometric turbidity units (NTU)) was the only exceedance of the benchmark values. The benchmark levels are used as guidance levels, since this sample location is not regulated under a specified stormwater discharge permit. PBS will coordinate the 2nd Quarter-2018 sampling from the manhole location during a measurable precipitation runoff event. If you have any questions regarding the enclosed material, please call me at 206.233.9639, Sincerely, Megan Nogeire, Project Scientist PBS Engineering and Environmental Inc. Review.

SAMPLE RECEIPT: Samples receipt information is recorded on the attached Sample Receipt Checklist. II. GENERAL REPORTING COMMENTS: Results are reported on a wet weight basis unless dry -weight correction is denoted in the units field on the analytical report ("mg/kg-dry" or "ugfkg-dry"). Matrix Spike (MS) and MS Duplicate (MSD) samples are tested from an analytical batch of "like" matrix to check for possible matrix effect. The MS and MOD will provide site specific matrix data only for those samples which are spiked by the laboratory. The sample chosen for spike purposes may or may not have been a sample submitted in this sample delivery group. The validity of the analytical procedures for which data is reported in this analytical report is determined by the Laboratory Control Sample (LCS) and the Method Blank (MB). The LCS and the MB are processed with the samples and the MS/MSD to ensure method criteria are achieved throughout the entire analytical process. III. ANALYSES AND EXCEPTIONS: Exceptions associated with this report will be footnoted in the analytical results page(s) or the quality control summary page(s) and/or noted below.

Refer to Figure 1 for sample location. Based on the review of precipitation data during the period from July 1 to September 30 of 2018 (i.e., 3r1 quarter) there was not a recorded precipitation event that generated an off -site discharge of stormwater during this period based on precipitation data and site knowledge. Precipitation data was measured at the Seattle Boeing Field (Station KBFI) located approximately 200 feet to the north from the "Z" Line Sampling Location. Data was obtained from the MesoWest website that is through the University of Utah's Department of Atmospheric Sciences (httns://rnesowest.utah.ed i). Upon review of the precipitation data, PBS identified one storm event that had a storm amount greater than 0.1 Inches during business hours. The event was on September 14, 2018 and reported 0,1 inches of precipitation over a 24-hr period. The rain was sporadic and based on weather observations a sampling attempt was not made. The precipitation data for September 14, 2018 is presented in Table 1. PBS will coordinate the 4th Quarter-2018 sampling from the manhole location during a measurable precipitation runoff evert, If you have any questions regarding the enclosed material, please call me at 206.233.9639, Sincerely, Digikally signed by rut , ofreMeganNogetre date: 2018.09.28 15:45:29.07'OD' Megan Nogeire, Project Scientist PBS Engineering and Environmental Inc.

Public Works 6200 Southcenter Blvd Tukwila, Washington Re: 2018 fourth Quarter Boeing Z Line Stormwater Sampling, Tukwila, Washington PBS Project Number 40407.026, City Project No: 91041204 Date Sampled: November 26, 2018 Dear Mr. Larson, PBS Attached please find a summary table of analytical test results, the sample collection field form, and a copy of the laboratory data report for samples collected on November 26, 2018 from the City Stormwater Outfall to Boeing Line "Z" located at the intersection of East Marginal Way South and South 81st Place in Tukwila (manhole 36-165) in Seattle, Washington. The sampling was conducted in accordance with the Stormwater Sampling and Analysis Plan, City Outfall to Boeing Z Line, PBS -March 16, 2016. Identification and visual observations of the stormwater sample point are presented below. A summary of the laboratory analysis results at the sample location is presented as Table 1 (attached). Rainfall amount on this day (24-hour period) totaled 1.36 inches (Source: Weather Underground — Seattle, Seattle Boeing Field (KBFI weather station)). Manhole 36-165: The sample point is a manhole that conveys runoff from East Marginal Way and is located Just upstream of the former Boeing plant Z-line storm sewer (see Figure 1). PBS collected the sample from the channel at the bottom of Manhole 36-165 on November 26, 2018. There was some floating solids observed during the sample collection but no visible sheen. The analyzed sample indicated that levels of total suspended solids (17 milligrams per liter (mglL)), zinc (71.5 micrograms per liter (pg/L), pH (7.6), lead (4.51 pg/L) and polychlorinated biphenyls (PCBs) (c0.001 Iµg/L) were within the adopted benchmark stormwater guidance levels (Washington State Department of Ecology Stormwater Sampling Manual A Guidance far the Industrial Stormwater General Permit dated December 2015). Turbidity (50 nephelometric turbidity units (NTU)) and copper (22.6 pg/L) were the only exceedance of the benchmark values. The benchmark levels are used as guidance levels, since this sample location is not regulated under a specified stormwater discharge permit. PBS will coordinate the 1st Quarter-2019 sampling from the manhole location during a measurable precipitation runoff event. If you have any questions regarding the enclosed material, please call me at 206.233.9639. Sincerely, Megan Nogeire, Project Scientist PBS Engineering and Environmental Inc.

II, GENERAL REPORTING COMMENTS: Results are reported on a wet weight basis unless dry -weight correction is denoted in the units field on the analytical report ("mg/kg-dry" or "ug/kg-dry"). Matrix Spike (MS) and MS Duplicate (MSID) samples are tested from an analytical batch of "like" matrix to check for possible matrix effect. The MS and MSD will provide site specific matrix data only for those samples which are spiked by the laboratory. The sample chosen for spike purposes may or may not have been a sample submitted in this sample delivery group. The validity of the analytical procedures for which data is reported in this analytical report is determined by the Laboratory Control Sample (LCS) and the Method Blank (MB). The LCS and the MB are processed with the samples and the MS/MSD to ensure method criteria are achieved throughout the entire analytical process. Ill.

MONITORING AND ASSESSMENT 10 CONCLUSION 11 80 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). 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 (NIS4). 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, aov/programs/wQ/stormwater/municipal/nhaselIww/wwphi ipermit. html Tukwila was first issued a Western Washington Phase II Municipal Stormwater Permit on January 17, 2007 (February 15, 2012 permit term), and June 17, 2009 Ecology modified the permit. On 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 becoming effective on August 1, 2019 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 Permit also requires by March 31 of each year the City provide an annual report for each previous year's activities that documents the City's compliance with the Permit, Both the annual report and the updated SWMP are to be posted on the City's website no later than May 31' of each year. 1 WOW Engrpp.JECTS1w• 6A PegjoomNPtr;S Program 1,9 sir 12IuIr tnnwr Reports and a wince Warer Mai arinera Pradrnaulllr III Anon/ Appel de YA 1' SWMP PI,n''11I4 SWMP Or,It BIua Wd,1a, dos 81 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 Operations and Maintenance • Special condition, Total Maximum Daily Load Requirements a Special condition, Monitoring and Assessment The following sections describe requirements of each program component and the City's planned activities to meet the requirements.

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.tukwilawa.gov/pubwkslnpdes.html. The public is encouraged to participate in the development of the SWMP Plan.
