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.

1. 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 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
o Public Involvement and Participation
o Illicit Discharge Detection and Elimination
o Controlling Runoff from New Development, Redevelopment and Construction
Sites
o 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
December 31, 2011, the City met the initial Permit requirements.

2. 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
Stormwater (NPDES) Permit. Phase II communities are those that:
o Own and operate a storm drain system
o Discharge to surface waters of the state
o Are located in urbanized areas
o 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.
However, D.O.E. has extended the Permit for a period of one year and will reissue the
current Phase II Permit, with no modifications, in July 2012.
As stated, the major program components listed in the Permit are as follows:
o Public Education and Outreach
o Public Involvement and Participation
o Illicit Discharge Detection and Elimination
o Controlling Runoff from New Development, Redevelopment and Construction
Sites.
o 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 II 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."
2. Catch Basin Labeling
o 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," or glue down metal marker stating "No Dumping
Drains tor River."
o 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
stenciling, or metal pavement markers. The City's Maintenance
Department has installed over 3,000 glue down metal pavement markers
to date.
o All inlet castings are required by City standards to be labeled "Outfall to
Stream - Dump No Pollutants
3. City Newsletter and Newspaper

2.3 ILLICIT DISCHARGE DETECTION AND ELIMINATION (IDDE)
2.3.1 Permit Activities
The City is required to implement an ongoing program to detect and remove illicit
connections, discharges, and improper disposal, including any spills not under the
purview of another responding authority, into the MS4 owned or operated by the City.
The goals and requirements of the program are as follows:
o 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.).
o 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.
o Develop and implement a program to detect and address non - stormwater
discharges, spills, illicit connections, and illegal dumping into the City's MS4.
o Inform public employees, businesses, and the general public of hazards associated
with illegal discharges and improper waste disposal.
o 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.
o Provide appropriate training to City employees on IDDE into the City's MS4.
o Establish a hotline number for public reporting of spills and other illicit
discharges. Maintain a record of all calls received and actions taken.
2.3.2 Current Activities
The City has completed the elements required for an IDDE program and others will be
developed as required. Current activities include the following:
1. Outfall Mapping
The City began a geographic system (GIS) mapping program in 2003 and to date,
has mapped all receiving water body outfalls, all public surface water pipes 8"
and larger that includes information such as pipe invert, material and its condition.
All GIS information is added to the City's GIS Database and will continue to be
refined as needed. The information is also provided upon request to the public.
2. Reporting Spill Hotline
The City has an advertised reporting phone number, (206) 433 -1860, where
illegal dumping and spills can be reported and is functioning as expected. In
addition, the City is notified through the DOE Environmental Report Tracking
System of Illicit discharges that have been reported directly to the DOE
3. Training Program
The City has an ongoing training program that consisted of the following
activities:

o Staff training for office personnel was conducted in June and November of
2011 on multiple stormwater subjects that included SWPPP, TMDL and
BMPs.
4. Video Inspection
The City's Surface Water Maintenance's inspection program is divided into five
zones. Video equipment is used to inspect storm water piping in these zones. This
2012 reporting period consisted of condition based video inspections. Illegal pipe
connections and questionable discharges are investigated and corrective measures
are taken when warranted.
5. Car Wash Program
As part of the City's ongoing public education program, a SudSafe Car Wash
program is in place. All organized charity car washing events must use this
program. In addition, facilities without a commercial wash base are allowed the
use of a sudsafe car wash kit providing the discharge is limited to the sanitary
sewer.
6. IDDE Ordinance
The City adopted a new IDDE Ordinance on February 16, 2010 that fully
complied with NPDES Permit requirements.

2.5 POLLUTION PREVENTION AND OPERATION AND MAINTENANCE
FOR MUNICIPAL OPERATIONS
2.5.1 Permit Requirements
This minimum control measure requires that the City provide a pollution prevention and
operation and maintenance program including a training component that has the ultimate
goal of preventing or reducing pollutant runoff from municipal operations. All elements
of the operations and maintenance program were required to be in place by February 16,
2010. The minimum elements included in this program component are:
1. Establishment of maintenance standards that are as protective, as or more
protective, of facility functions than those specified in Chapter 4 of Volume V of
the 2005 Stormwater Management Manual for Western Washington. The purpose
of the maintenance standards is to determine if maintenance is required on a
particular facility or structure. If maintenance is deemed necessary during
inspection, the following schedule is required for completion of the required
maintenance:
o Within 6 months for typical maintenance
o Within 9 months for maintenance requiring re- vegetation
o Within 1 year for wet pool facilities and retention /detention pond
o Within 2 years for maintenance that requires capital construction of less
than $25,000.
2. Develop and implement an operations and maintenance (O &M) program with the
ultimate goal of preventing or reducing pollutant runoff from municipal separate
stormwater system and municipal operations and maintenance activities.
3. Perform required inspections of stormwater facilities on a regular basis.
Inspections will be documented with the work needed or completed on the
stormwater facilities according to the Permit requirements for reporting.
4. Develop and implement a program to reduce the stormwater impacts from streets,
parking lots, roads, highways, and other lands owned, operated or maintained by
the City, including road maintenance.
5. Develop and implement a training program for City employees whose job
functions may impact stormwater quality.

2.5.2 Current Activities
The City has an active pollution prevention and operation and maintenance program
implemented by the City's Surface Water Maintenance Division. This program includes
the following activities:
1. Catch Basin Inspection
The City inspects all catch basins and inlets owned and operated by the City at
least once before the end of the permit term (minimum 5 -year rotating schedule).
If the catch basin has over 6 inches of deposited sediment in the sump, it will be
cleaned.
2. Conveyance System Inspection/Cleaning
The City's piped storm drainage system has been delineated into zones by the
Public Works staff. Pipe system maintenance is scheduled by zone, and each zone
is maintained on a 3 to 5 -year cycle. This includes repair of all pipes and catch
basins, with particular attention given to chronic problem areas and areas for
which complaints have been received from citizens.
3. Flow/Water Quality Facilities
The City inspects all surface water flow control and water quality facilities within
a three year cycle. Maintenance is performed on above ground facilities that
include vegetative control every year. Maintenance is performed on below ground
facilities that include structure repair and sediment removal once every three
years. Maintenance is performed as needed through the current circuit or
condition based inspection and compliant process.
4. Drainage Complaints
The City responds to all stormwater- related complaints. Complaints are submitted
to the City through Requests for Action (RFAs), Environmental Report Tracking
System (ERTS), City Council meetings, letters, e- mails, and telephone calls.
These complaints are forwarded to the appropriate division and /or to the
respective property owner /project site.
5. Problem Areas
Maintenance staff keeps an informal list of problem areas occurring in the City's
drainage system. These problem areas are inspected and problems corrected after
every major rainfall event. In addition, maintained every 3 to 5 years.
6. Video Inspection
The City maintains an annual closed circuit television (CCTV) inspection
schedule of its existing pipeline system to help identify illegal connections to
drainage systems, damaged, and obstructed sections of pipe. This information is
used to schedule repairs and further investigate illicit discharges and connections.

and others will be developed as required. Current activities include the following:
1. A TMDL has not been established for the City of Tukwila, so monitoring is not
required at this time. The Department of Ecology is currently conducting TMDL
analysis of the lower Duwamish River.
2. Outfalls
The City has developed and maintains a map of all MS4 outfalls as part of our
GIS mapping program and will continue to be developed.
3. The City has prioritized three receiving waters for visual inspections and will
continue with its monitoring.
4. The Department of Ecology is assessing Phase I Permittees monitoring plans.
Upon completion of assessment, Ecology will provide the guidance needed for the
Phase II Permittees to develop their long term monitoring plans.
2.6.3 Planned Activities
The City will continue with all programs and procedures currently in place. In addition,
the City will conduct the following activities in 2012:
1. Monitoring Plan
o Conduct field assessment on at least one high priority water body.
o Continue to participate in the regional, state, and local monitoring forums
to develop and integrate monitoring and assessment requirements.
o Prepare to develop a long -term monitoring plan once the Department of
Ecology provides further guidance.
3. CONCLUSION
This Surface Water Management Program has been prepared to demonstrate compliance
with the requirements of the NPDES Phase II Permit and outline planned activities for
2012. This SWMP will be a working document with updates until the final plan is to be
completed by the recent extended date of July 31, 2013.
There are multiple tasks that the City is undertaking to align itself with the Permit
