EXHIBIT"A" SCOPE OF WORK City of Everett Surface Water TMDUMunicipal Stormwater (NPDES) Permit Support for 2018-2021 Background Stormwater discharges from the City of Everett's municipal separate storm sewer system (MS4) are covered by the Western Washington Phase II Municipal Stormwater Permit (Permit). The Permit requires that the City comply with Total Maximum Daily Loads (TMDL) plans for receiving waters that were established before the current Permit was issued. The Washington State Department of Ecology (Ecology) plans to issue the next Permit in 2019. The City retained Brown and Caldwell (BC) to evaluate current and potential MS4 permit requirements related to impaired/polluted waters and TMDLs and help the City develop a strategy for addressing them. BC's findings and recommendations were described in a Technical Memorandum dated November 10, 2017. The City asked BC to prepare a scope and cost estimate for helping the City implement the initial recommendations contained in the Technical Memorandum, and provide additional NPDES/TMDL support if needed. Based on recent conversations with City staff, we understand the City would like BC to assist with the following: • TMDL Support o Review North, Wood, and Swamp Creek TMDL monitoring results to date o Revise QAPP for North, Wood, and Swamp Creek TMDL monitoring • Voluntary Monitoring Support o Summarize voluntary monitoring program findings to date o Perform B-IBI stressor evaluation o Prepare QAPP for E. Coli monitoring in TMDL creeks and Silver Lake o Prepare QAPP for voluntary monitoring program • Regulatory Support o Review and comment on proposed revisions to state fecal indicator criteria o Review and comment on the 2018 WQA • Microbial Source Tracking (if deemed appropriate based on TMDL toxicity source identification and evaluation results) 6/6/2018 1
