lead to stormwater management requirements for the City. A draft of the next WQA should be available for public review in late 2018 or early 2019. BC will review the draft WQA and prepare draft comments for the City. Our review will focus on water bodies in the City's jurisdiction. We will participate in a conference call to discuss the WQA and draft comments with City staff. We will then revise our draft comments, which will be provided to the City in a brief Word document. Deliverables • Draft and revised comments on Ecology's proposed changes to the WQS for recreational uses • Draft and revised comments on Ecology's next WQA Assumptions • Two BC staff will participate in two, 2-hour phone calls with City staff • BC will prepare one draft and one revised version of the comments in electronic format Task 4 Microbial Source Tracking BC will review the results of the TMDL sampling and TSIE activities performed by City staff in accordance with the updated QAPPs from Task 1. BC will meet with City staff to discuss the TSIE results and identify areas (if any) where microbial source tracking (MST) could help identify the potentially controllable sources (e.g., sewer leaks, homeless encampments, domestic animals). The MST results may help the City tailor control measures to address the key sources. In addition, the results could help the City demonstrate that it has implemented source controls to the maximum extent practicable. BC will update the Task 1 QAPP for the watershed that the City deems highest-priority for MST. BC will revise the updated QAPP per City comments. BC will also participate in a conference call to discuss Ecology's comments on the updated portion of the QAPP. BC will revise the QAPP accordingly. BC will meet one time with City monitoring staff to review sample collection and analytical procedures. City staff will then perform the sample collection per the QAPP. The City lab will analyze the samples for E. coli. The City lab will filter each sample and freeze the filters for potential shipment to the MST lab. Alternatively, City staff may filter the samples and preserve the DNA in the field, if the requisite field preservation methods are fully developed prior to the start of the MST sampling. BC and City staff will review the E. coli results approximately quarterly to identify samples for MST analyses. The City lab will ship the designated frozen filters samples to the MST lab for analyses using quantitative polymerase chain reaction (qPCR). Deliverables • Draft, revised and final update to QAPP for the selected watershed 6/6/2 01 8 4
