INFORMATIONAL MEMORANDUM
TO: Mayor Haggerton
Utilities Committee
FROM: Public Works Director
DATE: March 8, 2011
SUBJECT: NPDES Program
Project No. 93 -DR10
2010 Annual Report and 2011 Surface Water Management Program
ISSUE
Review the City's 2010 National Pollutant Discharge Elimination System (NPDES) Annual Report and
2011 Surface Water Management Program.
BACKGROUND
The National Pollutant Discharge Elimination System (NPDES) requires that the City implement a
comprehensive Stormwater Management Program (SWMP) which complies with the requirements
outlined in the City's NPDES Phase II permit that became effective February 16, 2007. The conditions
of the permit require that the City develop a SWMP and submit annual reports to the Department of
Ecology outlining our progress in meeting permit requirements by March 31st of each year.
The SWMP document commits the City to activities which have staffing, training, procedural, and
documentation requirements which the City must follow. The SWMP is updated annually to reflect any
required changes to our program and to provide greater detail as various programs are fully developed.
Once submitted to the DOE, this plan will be used to determine whether permit obligations are being
met.
DISCUSSION
City staff completed the 2010 Annual Report that reflects activities completed by the City in 2010. In
addition, staff also updated the 2010 SWMP to reflect permit requirements for 2011. All 2010 updates
are printed in blue for reference. The 2010 Annual Report must be signed by the City administrator and
both documents must be sent to the DOE by the reporting deadline of 3/31/2011.

City of Tukwila
Listing of Barriers to LID Implementation
• The city's stormwater code does not actively encourage LID implementation. Rather "In
order to achieve the City's goal of increasing the amount of development with less
impervious surface, the Director may approve exceptions to Public Works standards..."
(City Code 14.30.130.B.1 - Exceptions). This is followed by a long list of justifications
that the applicant must demonstrate before an LID practice can be approved. The city
approach of allowing LID implementation only by exception is not an effective approach
to promote LID use for projects.
• Limited staff time
• Perception that LID is difficult to implement in a built -up city, retrofits are challenging.
• The lack of a map showing high - potential LID areas within the city limits. (Such a map
would combine natural elements such as infiltrative soils, appropriate water table depth
and favorable topography /slope conditions, among others.)
Other Potential Barriers*
• There is a perception that LID is not proven, technology is untested, and has not been
tested by time; general public and elected officials don't yet trust LID.
• General public and elected officials lack working knowledge of LID; elected officials
could be advocates for LID and the general public could demand LID with increased
knowledge and information.
• Information is needed on which methods will work where and under what conditions,
maintenance requirements; and that LID can work and be aesthetically pleasing.
•, LID is perceived as expensive compared to conventional methods.
• Construction materials for LID can be more expensive (transportation costs of pervious
pavement, for example, especially in more rural areas with fewer suppliers in
proximity).
• Maintenance needs and costs are unknown in some circles, lack of widespread
knowledge; in some cases, maintenance staff lack adequate training and available time
to maintain LID facilities.
•_ Planning department counter staff, permit reviewers, inspectors, and enforcement staff
lack adequate training to provide guidance, review permit applications, and inspect LID
facilities.
• Professional engineers struggle with signing off on plans including LID because LID is
not as tested and proven as conventional stormwater management methods.
• Developers lack knowledge of LID: developers that are more knowledgeable produce
better products for review (during permit review process).
25
• If incentives for LID are granted for private property, local government would need
dedicated staff to conduct initial inspection and repeated inspections to ensure systems
continue to work and that incentives are still warranted.
• LID is often in conflict with other perceived needs (e.g., wider roads for emergency
vehicle access).

City of Tukwila
LID PRACTICES
Low Impact Development (LID) is an approach to land development that uses various
land planning and design practices and technologies to simultaneously conserve and
protect natural resource systems and reduce infrastructure costs. LID still allows land to
be developed and /or redeveloped, but in a cost - effective manner that helps mitigate
potential environmental impacts.
There are numerous design practices and technologies developers can reasonably use to
implement nonstructural LID techniques to prevent stormwater impacts. The City
recognizes the Low Impact Development Technical Guidance Manual for Puget Sound
for this purpose.
Developers can work with City staff and the general public during the initial stages of
planning to identify, promote, and measure LID.
To developers, LID can offer infrastructure savings, reduction of land clearing and
grading cost, reduction of stormwater management costs and a way to respond to
increasingly stringent environmental regulations.
For Tukwila, LID can help contain burgeoning street and storm water management costs,
balance growth needs with environmental protection and foster public /private
partnerships.
For community residents, LID can encourage local environmental stewardship and
protect regional water quality by reducing sediment, nutrient, and toxic loads to water
bodies. In addition, it can provide shading for homes and properly orients homes which
reduce monthly utility bills.
For the environment, LID preserves integrity of ecological and biological systems and
reduces impacts to our local terrestrial, aquatic plants, and animals. In addition, it
preserves trees and natural vegetation.
27
To help guide the implementation of LID, the City has in place Ordinance #2274 that
accounts for LID. The ordinance authorizes the Public Works Director to allow
exemption to its Public Works standards, including street standards, to achieve the City's
goal of increasing the amount of development with less impervious surface. The
applicant shall provide justification for each exception and will be assessed on the
following criteria:
1. The result will compensate for or be comparable with surface water flow control
and treatment that is in the public's interest.
2. The exception contributes to and is consistent with achieving low effective
impervious surface area within a development.
3. The exception contains reasonable assurances that low effective impervious
surfaces will be achieved and maintained.
4. Granting of the exception will not threaten public health and safety.
5. The exception meets or is consistent with generally accepted engineering design
practices.
6. The exception promotes one or more of the following:
a. Innovative site or housing design;
b. Increase in on -site surface water retention using native vegetation;
c. Retention of at least 60% of natural vegetation conditions over the site;
d. Improved on -site water quality beyond that required in current standards
adopted by the City;
e. Retention or recreation of predevelopment and/or natural hydrologic
conditions to the maximum extent possible; and
f. Reduction of effective impervious surface to lowest extent practicable.
7. The exceptions do not present significantly greater maintenance requirements at
facilities that will eventually be transferred to the public ownership;
8. Covenant, conditions, and restrictions necessary for native growth protection
easements, impervious surface restrictions and other such critical features
necessary for the exceptions will be recorded against and will be binding against
all affected properties.
9. The director may require a monitoring and evaluation plan in order to measure
performance of specific elements in the exceptions.
Exceptions requiring approval under the land use codes, such as parking and landscaping,
must be made to the Department of Community Development.
28
The City has in place the following LID measures
Current Practices
• Consideration is given to permeable pavement designs.
• Promote rain gardens.
• Allow for grass swales.
• Protection of native and sensitive areas.
• Allow for infiltration systems that are located in specific drainage basins.
• Consideration is given for credit allowances.
• Construction of grasscrete entry ways for the Fire Department.
• Construction of pervious pavement.
Potential and Planned Non - Structural
• Promote minimization of total disturbed areas.
• Minimize soil compaction.
• Protect natural flow pathways.
• Reduce impervious surfaces.
• Amend soils.
• Create brochures promoting LID
• Use City newsletter to solicit LID input.
Potential or Planned Schedule Requirement and Implementation
• Encourage techniques that take advantage of natural resources for both functional
and aesthetic qualities.
• Review open house meetings with developers and general public.
• Determine LID implementation where feasible.
• Implementation of LID once DOE has determined the required performance
standards for the next permit phase in 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, 2010, the City meets the initial Permit requirements.

2. NPDES PHASE H PROGRAM COMPONENTS
Tukwila is defined as a Phase II community by the Washington State Department of
Ecology and, therefore, is required 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
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 expires on February 15, 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, 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
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 ".
o All paving projects, both private and public, that pave around an existing
catch basin are required to label all catch basins with a torch down
pavement decal stating "Dump No Waste - Drains To Stream ".
o All inlet castings are required by City standards to be labeled "Outfall to
Stream - Dump No Pollutants ".
3. City Newsletter Article
The City of Tukwila publishes a newsletter 5 times a year and includes articles
concerning stormwater related topics at least 4 times a year. Typical topics
covered include:
o Car Washing
o Illegal dumping of materials in storm drains

development, redevelopment, and construction site activities. The existing program
applies to both public and private projects, including roads. The current compliance
activities associated with the above permit requirements are summarized below:
o The City amended city codes and revised standards to meet permit requirements
for development, redevelopment, construction and post - construction stormwater
management, including escalating enforcement provisions for illicit discharge
originating from construction sites. The development related codes became
effective February 15, 2010 which are included in Ordinances 2274 and 2275.
In summary, for the purpose of development and redevelopment the City follows the
listed items:
1. Design Standards
The City uses the minimum design standards of the 2009 King County Surface
Water Design Manual with an option to use DOE's Surface Water Management
Manual for Western Washington.
2. Construction Site Inspection
All sites are inspected by the City prior to the start of construction. The City
tracks and maintains inspection records and enforcement actions by staff.
3. Construction Standards
City's Infrastructure Design and Construction Standards, and WSDOT Standard
Specifications for Road, Bridge, and Municipal Construction are used for
construction standards.
4. Enforcement
TMC 8.45 provides for a system of escalating enforcement procedures necessary
to sustain the existing codes and standards throughout the construction and
development process.
5. Notice of Intent
The City provides Notice of Intent for Construction Activity and Notice of Intent
for Industrial Activity to representatives of proposed new development or

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 must 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, 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.

the City that is not required to have coverage under the Industrial Stormwater
General Permit.
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 on an
annual basis. Maintenance is performed as needed and includes vegetative
control, structure repair, and sediment removal. Maintenance is performed at
least once every 10 years, or 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
ditch system. These problem areas are 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.
7. Hazardous Material Spills
Tukwila Fire Department responds to hazardous material spills. Though City
maintenance crews are often the first group to respond to spill complaints, they
are limited to the use of absorbent pillows and oil absorbing particulate materials.
2.5.3 Planned Activities
The City will continue with all programs and procedures currently in place. In addition to
these, the City will conduct the following activities in 2011:
1. Procedural Review
o The City will continue to review and revise, when necessary, all current
practices that reduce impacts from runoff or maintenance activities
associated with municipally owned or operated streets, parking lots, and
roads.
o The City will continue to develop and implement a more formalized plan
for inspection and documentation of all catch basins, inlets, stormwater
treatment and flow control facilities owned and operated by the City. The
plan will include performing spot checks on potentially damaged
permanent treatment and flow control facilities after major storm events.
o The City will continue to review and revise, as necessary, the current
SWPPP.

this permit term, with the following exceptions:
o Water quality monitoring required for compliance with TMDLs (Total Maximum
Daily Pollutant Loads).
o Any sampling or testing required for characterizing illicit discharges pursuant to
the Illicit Discharge Detection and Elimination section of the permit.
2.6.2 Current Activities
The City currently has several of the elements required for a monitoring program in place
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.
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 2011:
1. Monitoring Plan

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
2011. This SWMP will be a working document until the final plan is to be completed by
August 19, 2011.
There are multiple tasks that the City is undertaking to align itself with the Permit
requirements and the many elements that need to be accomplished and built upon.
The Public Education and Outreach Program has been implemented and exciting
opportunities exist to be even more creative in developing a program that reaches out
with useful information that will benefit the general public, business district, and
industrial community.
The City has an ongoing Illicit Discharge Detection and Elimination Program in place
and will continue to update it with staff training, enforcement of the IDDE ordinance, and
distribute additional educational materials.
With the knowledge base that the City has in place, controlling runoff from new
development, redevelopment, and construction sites will now be more manageable.
With the use of various SWPPP's and the 2009 King County Surface Water Design
Manual, the City has a program in place that meets its obligation of pollution prevention
for municipal operations.
Additional information on the City's NPDES program can be found online at
