BACKGROUND On March 11, 2013, City staff received a call from a business owner on Andover Park East reporting sewage coming up in his parking lot. Staff discovered that the 12 -inch pipe between Andover Park East and Andover Park West was full of sewage and not flowing. Maintenance staff then tried jetting the sewer line, and the jet head was only able to go out about 150 feet of the 430 foot sewer line. The sewer flow rate improved, but the jet head could go no further. When the jet head is unable to access the pipe, it usually indicates there is a major break in the sewer pipe and has caved in. On March 12, 2013, staff noted gravel in the downstream manhole and determined that the sewer pipe had failed and a sink hole had formed near the railroad tracks. A temporary rental pump has been installed to bridge the railroad tracks and the plugged sewer line. In February 2011 this section of sewer pipe failed just east of Andover Park West resulting in a major excavation for repair of the sewer and water lines. In 2012 the City of Tukwila received a Public Works Trust Fund Loan for the relining of sewer pipes in this portion of the CBD for 2013. The new failure is about 150 feet east of the failure which occurred in 2011. ANALYSIS Approve the Resolution which declares an emergency and authorizes Public Works to immediately stabilize the damaged sewer system with a construction contract exempt from competitive bidding. The scope of this sewer stabilization project is to install a rental pump with temporary piping between the railroad ties so that train traffic is not blocked by sewer piping laying over the train tracks and then on to a manhole near Andover Park West. This temporary system will allow the City time to hire a consultant to design a repair project and use normal bidding procedures in hiring a contractor for the repair. Staff will return to Committee at a later date with a Consultant Agreement for the design work. RECOMMENDATION The Council is being asked to approve the Resolution declaring an emergency for the APW /APE Sewer Repair March 2013 Project and consider this item at the March 25, 2013 Committee of the Whole meeting and subsequent April 1, 2013 Regular meeting.

DATED this day of , 20 CITY OF TUKWILA CONSUL ANT Mayor, Jim Haggerton B : / Printed Name: Title: "-e/JtOfir- Attest/Authenticated: Approved as to Form: City Clerk, Christy O'Flaherty Office of the City Attorney CA revised : 1-2013 Page 5 10 ORIGINAL PAGE NO OF 14-PAGES EXHIBIT A Scope of Work City of Tukwila 2013 Central Business District Sewer Rehabilitation March 2013 BACKGROUND The portion of Tukwila's Central Business District (CBD) for this project is bounded on the north by Minkler Boulevard, by South 180th Street on the south, and by Andover Park East and Andover Park West to the east and west, respectively. This area was first developed in 1967 by the Sanunamish Commercial Company as an industrial park warehousing area. The developer installed asbestos-concrete (AC) pipe for the sanitary sewer system. The design life of AC pipe is 40 years, and the existing pipe has begun to fail. In 2007 and 2011, the sanitary sewer system in the areas of the City of Tukwila (City) experienced collapsed pipes due to the age and condition of the pipes. The repair of the collapsed pipe in those years cost the City over $500,000 due to the depth of the pipe and seasonal high groundwater. To prevent the collapse of any more sewer pipes in this area of the CBD, which would be likely to result in the discharge of sewage into the Green River, the City has decided that the sanitary sewers in this area of the City need rehabilitation by lining with cured-in-place-pipe (CIPP). There is approximately 3,500 feet of 8-inch diameter and 4,000 feet of 12-inch diameter gravity sewer main that has been identified for lining. Additionally, approximately 10 manholes that have sustained corrosion are to be lined with cementitious coatings. Improvements made as part of this project are focused primarily on the structural rehabilitation of the pipe and manholes and secondarily on inflow and infiltration control. The City has received a Public Works Trust Fund loan for this work. The City has not had hydraulic capacity problems with the sewer in this area. The area is fully developed at the present time. In HDR's 2005 Comprehensive Sanitary Sewer Plan Conveyance System Analysis, computer hydraulic modeling found all the pipes were at less than 60-percent capacity. If the pipes were relined, there could be a small reduction in capacity of the pipes, but the coefficient of friction will be reduced, due to the smooth inside surface of the new pipe offsetting the reduced inside diameter. CIPP was chosen as the preferred rehabilitation method because it costs less than open-cut replacement or pipe bursting while still maintaining the needed conveyance capacity. Another component of work to be included in the project is the installation of a new manhole in the existing sewer in the 300 block of Andover Park East. Currently the distance between manholes in this block is 600 feet, which is 200 feet longer than the maximum spacing recommended by the Washington State Department of Ecology's Guidelines for Sewerage Works Design. The City has attempted to install a manhole in this area once already, but prolific groundwater and running sands threatened the stability of the excavation. The City abandoned the attempt and will now approach the project with a geologic exploration and development of a dewatering and shoring plan prior to construction. Included in this scope is the hydrogeologic analysis followed by preparation of design and bidding documents for the new manhole installation. This Scope of Work describes engineering services for the City of Tukwila's 2013 Central Business District (CBD) Sewer Rehabilitation project. 08/30/12 \ TIJKAS40 \ 2012 Rthnbilitaion of Sammy Sewer in the Area orrukwila's Central Business District Proposal \ Contract \ PSA_SOW_TUK_2(113 CBI) Sewer Rehabilitation.doc 11 City of Tukwila 2013 Central Business District Sewer Rehabilitation ORIGINAL 1 PAGE NO 1 01=14- PAGES Exhibit A Scope of Work The work will be performed under the following Tasks: 1.

BACKGROUND The NPDES Program requires that the City implement a comprehensive SWMP that complies with the requirements outlined in the City's NPDES Phase II permit which became effective February 16, 2007 and was reissued August 1, 2012. On August 1, 2013 an updated NPDES Phase II permit will be in effect. The conditions of the existing and updated permit require that the City develop a SWMP 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 document commits the City to activities which have staffing, training, procedural, and documentation requirements that 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 2012 Annual Report, which reflects activities completed by the City in 2012. In addition, staff also updated the 2012 SWMP to reflect permit requirements for 2013. All 2013 updates are printed in blue for reference. The 2012 Annual Report must be signed by the City Administrator and both documents must be sent to the DOE by the reporting deadline of March 31, 2013. RECOMMENDATION Information only.

CONCLUSION 18 City of Tukwila Stormwater Management Program 2 of 18 March, 2013 40 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). 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. 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 D ccunhcr° , 20 II 2, the City met the Permit requirements. City of Tukwila Stormwater Management Program 3 of 18 March, 2013 41 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 (NPDES) Stormwater 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. As a. base, 1.I community, Tukwila applied far and was issued a. N2".
