Sincerely, WSB & Associc�tes,Inc. � � � � -�- � ����� � �-- Jesse Carlson Bob Barth Water Resources Project Manager Senior Project Manager Enclosure ef City Administrator Mayor Date W:�NPDESUIS4�Proposals�2013�Shakopcc-MS4 Proposal.doc Exhibit A Scope of Design Services MS4 Program Update City of Shakopee WORK PLAN Phase 1 Phase 1 includes the steps necessary to complete the application for reauthorization and submit to the MPCA for approval. 1. Project Management This task includes planning and coordination of all work tasks, establishment and monitoring of budgets, meetings, and correspondence with the City of Shakopee. The project manager will serve a primary role in the tasks necessary to meet the MS4 permit revisions. Jesse Carlson is proposed to manage the project for WSB &Associates, Inc. (WSB). 2. Data Collection Available data will be collected from the City of Shakopee, as necessary, to prepare the application for reauthorization. Much of this data was gathered during the MS4 program assessment completed in 2012; however an additional request for data may be necessary as we complete the application and permit revisions. 3. Develop Application for Reauthorization The information gathered during the self assessment and gaps analysis completed in 2012 will be used to complete the application for reauthorization to receive permit coverage. The City is required to complete this by December 30, 2013. 4. Draft SWPPP & Implementation Schedule The information gathered during the self assessment and gaps analysis completed in 2012 will be used to develop a draft summary of the major SWPPP components for the five year permit cycle (2013-2018). This spreadsheet will incltiide a unique identifier, BMP description, measurable goals, and a timeline for completing each SWPPP activity. This draft SWPPP will include completing the activities identified below: Identify Partnerships This activity includes identifying if new partnerships are warranted and Ltpdating the appropriate BMP sheets. This will include a summary of existing partnerships the City currently has. Prioritize Education This activity will include recommendations for high prioriry stormwater related issues to be emphasized in education and outreach during the permit term(e.g. specific TMDL reduction targets, changing local business practices, promoting adoption of the residential BMPs). Exhibit A 1 System Mapping The System Mapping activity will include a procedure and process for updating the storm sewer system map, if gaps were identified during the program assessment. If map updates are necessary, a schedule will be included along with measurable goals. Pond Assessment Procedures This activity will include identifying procedures and methods for evaluating the TSS and TP treatment effectiveness of MS4 owned/operated ponds within the City. Measurable goals and a schedule for completing this activity will be included. Discussion will be included regarding WSB's Storm Water Asset Management Program (SWAMP), which is intended to fulfill this MS4 requirement as well as prioritize pond inspection and maintenance to occur in a cost effective manner. Training Development of a comprehensive training program is critical to the foundation of any MS4 program. It is important to communicate to all City staff how their role may be impacting stormwater. WSB completes annual training for numerous MS4 communities. We will recommend the incorporation of this training or something comparable into your annual program. TMDLs This activity will include taking the approved TMDLs that were identified during the program assessment process and identifying all activities that will be completed to achieve compliance with the TMDL Waste Load Allocation (WLA)reduction requirements. This will include identifying progress towards meeting the TMDL goals, BMPs either implemented ar planned to be implemented, an estimate of cumulative load reductions, and a narrative describing what strategies will be taken if the WLA is not being achieved by the desired date. This draft implementation schedule can be used by City staff for future planning of SWPPP related budgets, staff, and resources that will be needed to meet the MS4 permit requirements. The City is required to complete this by December 30, 2013. 5. Organization Chart An organizational chart will be developed to identify what departments are responsible for specific BMP activities. The MPCA has identified during MS4 audits that developing an organizational chart is critical for MS4's to be able to properly assign tasks and communicate to all departments that they have an active role in implementing the MS4 permit requirements. Exhibit A 2 Phase 2 Phase 2 includes the steps necessary for the City of Shakopee to take in order to revise their MS4 program to meet the new permit requirements once their MS4 permit coverage has been extended. It is anticipated that work will not need to be initiated until May 29, 2014 with an ultimate completion date of May 29, 2015. 1. Enforcement Response Procedures WSB will develop the Enforcement Response Procedures (ERPs) describing procedures and circumstances for the implementation of verbal warnings, written notices, and escalated enforcement measures. The enforcement response procedure will be developed to compel compliance with the illicit discharge detection and elimination, construction site erosion and sediment control, and post-construction stormwater management requirements. 2. Written Procedures Written procedures will be created for pollution prevention/good housekeeping, responding to known/suspected illicit discharges, completing site plans reviews and site inspection, storm sewer inspections and maintenance, employee training, and program documentation. These may come in the form of checklists, BMP cut sheets, and standardized inspections forms/letters. 3. Pond Inventory The Ciry will need to submit the MPCA required pond inventory within 12 months of the date the permit coverage is extended. It is assumed that the City has comprehensive map of their system; however, if significant work is necessary to update the storm water system mapping WSB will provide a separate scope for the completion of this work. 4. Ordinances This activity includes revisions to the City's Ordinance No. 807 regarding water resources management to address the new MPCA constniction general permit,requirements for meeting the new MS4 regulatory mechanisms which include provisions for volume control on new development and redevelopment, and also consider the new precipitation frequency estimates (Atlas 14). 5. Long-term Maintenance This task will include reviewing the existing regulatory mechanisms to determine how the City ensures long-term maintenance of private systems draining to the City's storm sewer system. This will inchide developiug post constniction regulatory language that will allow the City to conduct inspections, perform maintenance, and assess costs to maintain struchiral stormwater BMPs constructed after the effective date of this permit. 6. Facilities Inventory The Facilities Inventory will include completing a GIS inventory of all municipally owned/operated facilities. This inventory will include a map and a spreadsheet of all material being stored along with BMPs designed to prevent discharges of polhitants in stormwater. Exhibit A 3 7. BMP Inspection Forms The City will be required to inspect structural stormwater BMPs annually, stormwater ponds and outfalls once during the five year permit cycle, and complete quarterly inspection of stockpiles, and starage and material handling areas as identified during the facilities inventory. The City currently has a system to electronically track these inspections. As a part of this task the inspection forms will be modified to meet the new permit requirements. Additional Services The following are potential items of additional work that may be encountered as the project proceeds: • Record keeping evaluation and recommendations • Integration of the CIP study, as necessary, for meeting future TMDL goals • Updates to stormwater system mapping • Complete an evaluation of the TSS and TP treatment effectiveness of MS4 owned/operated ponds • Evaluation of the feasibility of BMPs to be implemented during redevelopment Exhibit A 4
