2011 Annual Report and 2012 Stormwater Management Program
ISSUE
Review the City's 2011 National Pollutant Discharge Elimination System NPDES) Annual
Report and 2012 Stormwater Management Program.
BACKGROUND
The National Pollutant Discharge Elimination System requires that the City implement a
comprehensive Stormwater Management Program (SWMP) which complies with the
requirements of the City's NPDES Phase II permit. The Phase II permit has been extended for
one year with the same requirements in effect. The conditions of the permit require that the City
update its SWMP and submit annual reports by March 31 of each year to the Department of
Ecology (DOE) outlining our progress in meeting permit requirements.
Once submitted to DOE, the 2011 Annual Report and 2012 SWMP will be used to determine
whether permit obligations are being met.
ANALYSIS
Staff completed the 2011 Annual Report that reflects activities conducted by the City in 2011. In
addition, staff updated the 2011 SWMP to reflect permit requirements for 2012. All 2012
updates are printed in blue for reference. The 2011 Annual Report was signed by the City
Administrator on March 14 and both documents were sent to the DOE on March 20 and met the
reporting deadline of March 31, 2012.

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 must comply with the Phase II Municipal Stormwater
Permit.
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
issued by the DOE. 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
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
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
Deceiiiber 31, 2 1 1, the City met the initial Permit requirements.

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
Stormwater NPDES) 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
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.
Phase II communities were required to complete a NPDES Phase II Stormwater Permit
Application and submit to the DOE by March 10, 2003. The NPDES Phase II Permit was
issued to Tukwila on January 17, 2007 and went into effect on February 16, 2007. The
Permit was modified on June 17, 2009 and was due to expire February 15, 2012.

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 future requirements.
2.1 PUBLIC EDUCATION AND OUTREACH
2.1.1 Permit Requirements
Section S5.C.1 of the Phase 11 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.

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 read
"This Stream Is In Your Care."
Catch Basin Labeling
All new public or private catch basins are required by City standards to be
labeled with a torch down pavement decal stating "Dump No Waste
Drains to Stream," Of glue doowi riietal iiiarker stating "No l:: uirii.pi.rq)
l gains tor River.'
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

purview of another responding authority, into the MS4 owned or operated by the City.
The goals and requirements of the program are as follows:
Develop a municipal storm sewer system map that includes information on the
City's MS4 (for example, outfalls, receiving waters, connection points, and areas
that don't discharge to surface water, etc.).
Effectively prohibit, through ordinance or other regulatory mechanism, non
stormwater, illegal discharges, and dumping into the City's MS4, including
locating priority areas likely to have illicit discharges.
Develop and implement a program to detect and address non- stormwater
discharges, spills, illicit connections, and illegal dumping into the City's MS4.
Inform public employees, businesses, and the general public of hazards associated
with illegal discharges and improper waste disposal.
Implement procedures for program evaluation and assessment which includes a
program to track spills and illicit discharges (both number and type), record
inspections made and any feedback received from public education effort.
Provide appropriate training to City employees on IDDE into the City's MS4.
Establish a hotline number for public reporting of spills and other illicit
discharges. Maintain a record of all calls received and actions taken.
