1906 INFORMATIONAL MEMORANDUM
TO: Mayor Ekberg
Utilities Committee
FROM: Bob Giberson, Public Works Director

DATE: March 11, 2016
SUBJECT: NPDES Program
Project No. 99341210
2015 Annual Report and 2016 Surface Water Management Program Plan
ISSUE
Review the City's 2015 National Pollutant Discharge Elimination System (NPDES) Annual
Report and 2016 Surface Water 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 updated NPDES Phase II permit which
became effective August 1, 2013 and was modified January 16, 2014. The conditions of the
existing and updated permit require that the City develop a SWMP Plan and submit annual
reports to the Department of Ecology (DOE) that outlines our progress in meeting permit
requirements by March 31 of each year.
The SWMP Plan document commits the City to activities which have staffing, 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 by DOE to determine whether permit obligations are being met.
DISCUSSION
City staff has completed the 2015 Annual Report, which reflects activities completed by the
City in 2015. In addition, staff also updated the 2016 SWMP Plan to reflect permit
requirements for 2016. All 2016 updates are printed in blue for reference. The 2015 Annual
Report must be signed by the City Administrator and both documents electronically
submitted to DOE by the reporting deadline of March 31, 2016.
RECOMMENDATION
Information only.

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) Plan as required by the NPDES Phase II Permit.
The SWMP Plan was developed to reduce 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 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
• Pollution Prevention and Operation and Maintenance for Municipal Operations
• Coordination
• Compliance with Total Maximum Daily Load Requirements
• Monitoring and Assessment
The Permit requires that the City:
• Report annually (by March 31 of each year) on the SWMP Plan implementation from
the prior year.
• Submit annually (by March 31 of each year) a SWMP Plan that describes proposed
surface water management program activities for the coming year.
• Develop a SWMP Plan that includes an ongoing program for gathering, tracking,
maintaining, and using information to evaluate its SWMP Plan development,
implementation and permit compliance and to set priorities.
• Coordinate with other permittees on stormwater- related policies, programs, and
projects within adjoining or shared areas.
• Coordinate with City departments to eliminate barriers to compliance with the terms
of the permit. Include a description of coordination in the Annual Report no later than
March 31, 2016.
19
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:
• 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
Web site 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.
As stated, the major program components listed in the Permit are as follows:
• Public Education and Outreach
• Public Involvement and Participation
• Illicit Discharge Detection and Elimination
• Controlling Runoff from New Development, Redevelopment, and Construction Sites
• Pollution Prevention and Operation and Maintenance for Municipal Operations
• Coordination
• Total Maximum Daily Load Requirements
• Monitoring and Assessment
The following sections describe requirements of each program component, the City's current
activities, and what the City's planned activities are to meet the requirements. In general, the
City of Tukwila is currently performing all previously required NPDES Phase II Permit
activities and has programs in place to address the updated Permit requirements.
20
1. PUBLIC EDUCATION AND OUTREACH
1.1 Permit Requirements
The Permit (Section S5.C.1.) requires the City to:
• Target and implement an educational and outreach program that will build general
awareness specific to the general public, businesses, engineers, contractors,
developers, development staff and land use planners and other City employees
that will help to reduce and eliminate behaviors and practices that cause or
contribute to adverse stormwater impacts.
• Implement an outreach program that targets a selected audience with the purpose
of improving their understanding and behaviors that impact surface water.
• Create stewardship opportunities and/or partner with existing organizations to
encourage residents to participate in activities such as stream teams, storm drain
marking, volunteer monitoring, riparian plantings and education activities.
• Measure the understanding and adoption of the targeted behaviors for at least one
selected audience and one selected topic.
• Track and maintain records of public education and outreach activities.
1.2 Current Activities
The City of Tukwila has an active public educational and outreach program regarding
general impacts of stormwater on surface waters with the following target audiences:
• The general public with an emphasis on school age children in science based
classrooms.
• Carpet cleaning, landscaping, automotive /truck, and restaurant businesses.
• Residents/homeowners, apartment managers /owners.
• City development staff, land use planners, maintenance personnel and other City
employees.
• The City of Tukwila partners with Forterra, EarthCorps and the Friends of
Duwamish Hill Preserve to provide stewardship training and restoration activities
in Tukwila's parks and shoreline areas. At least once a month volunteers gather
to do restoration and conservation work in Tukwila directly affecting the water
quality, natural habitat and vegetation within the Duwamish/Green watershed. In
conjunction with these volunteer events the City of Tukwila hosts an annual
Healthy Earth, Healthy you 5k and tree planting involving people in learning
about the Duwamish watershed and how they are a part of the cleanup. The City
also works with Duwamish Clean -up Coalition, actively participating in the
Duwamish Alive! Restoration and community education activities throughout the
year on three restoration sites.
• The City expanded its public education and outreach program with access to

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. A TMDL has not been established for the City of Tukwila at this
time, consequently no action needed.
8. MONITORING AND ASSESSMENT

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 Surface Water 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 currently implements the 2009 Surface Design Water Manual and will adopt the
2016 Manual by December 31, 2016, for controlling runoff from new development,
redevelopment, and construction sites. Also, the City will prepare to adopt LID measures
which will be mandated by December 31, 2016.
The City of Tukwila's Operations & Maintenance (O &M) is very active in all areas of permit
compliance. It should be noted; The 2016 King County Surface Water Design Manual
have new maintenance standards that O &M will follow. The City is preparing to adopt these
standards by December 31, 2106.
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.
