2014 Annual Report and 2015 Surface Water Management Program Plan
ISSUE
Review the City's 2014 National Pollutant Discharge Elimination System (NPDES) Annual
Report and 2015 Surface Water Management Program (SWMP) Plan.
The NPDES Program requires that the City implement a comprehensive SWMP Plan that
complies with requirements outlined in the City's updated NPDES Phase 11 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) outlining 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 to determine whether permit obligations are being met.
DISCUSSION
City staff completed the 2014 Annual Report, which reflects activities completed by the City
in 2014. In addition, staff also updated the 2015 SWMP to reflect permit requirements for
2015. All 2015 updates are printed in blue for reference. The 2014 Annual Report must be
signed by the City Administrator and both documents electronically submitted to the DOE by
the reporting deadline of March 31, 2015.
Information only.

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 -paint 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, 2015.
City of Tukwila
Storm water Management Program 1 of 13 March, 2015 11
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 Stonnwater Permit. Approximately 100 other

requirements into the City permit process. Coordination begins atthe pre-application stage whereas a Plan
Review/Routing Slip, along with the pre-application package, is forwarded to various City departments including Fire,
Police, Building, Planning and Public Works. Public Works engineering staff and the Phase 11 Permit representative meets
weekly to provide plan review and comments to proposed private development projects within the City. Public Works
projects are also reviewed by individual departments. Plans are distributed to various departments via a formal routing
form for further review which includes site visits to determine site conditions. Included in coordination efforts is the
City's Operations and Maintenance (O&M) whereas proposed project plans are routed for review and comments in
relation to the City's stormwater conveyance system as well as all other functions of O&M. Internal coordination is
ongoing and is improved upon when gaps are identified and or new information is available.
