reports, preparation of semi-annual reports using specified CEDEN templates, and preparation of Annual Reports according to Los Angeles RWQCB templates. South Orange County Water Quality Improvement Plan, Monitoring and Assessment Program, Orange County, California. Mr. Tringali led the development of a Monitoring and Assessment Program plan (MAP) and Quality Assurance Program Plan (QAPP) for Orange County. These plans were prepared for the South Orange County Watershed Management Area as partial fulfillment of the requirements of the Regional MS4 N PDES Permit. The MAP is a primary component of the larger Water Quality Improvement Plan developed for the WMA and documents the strategies and methods that Orange County and other Copermittees will use to monitor and assess progress of water quality improvement strategies, and the conditions of receiving waters and discharges from the MS4 under wet weather and dry weather conditions. North Orange County Dry Weather Reconnaisance Monitoring (DWM) Program Assessment, Orange County, California, 2019. Mr. Tringali supported technical evealuation of the County's DWM Program and provided recommendations to improve its effectiveness and efficiency, particularly for the Permittee's illicit discharge detection and elimination (IDDE) Program. Mr. Tringali led or supported other scientists with a variet of data analyses using North Orange County historical data including statistical power analysis, Mann -Kendall trend analysis, and joint/conditional/marginal probability analyses. Based on the results of these analyses, Mr. Tringali assisted with the identification and definition of multiple near- and long-term recommendations to the County's random and targeted outfall monitoring design that would more efficiently assess and track average background characteristics of dry weather discharges in the region, prioritize outfalls for dry weather discharge monitoring, efficiently detect potential ID/ICs, and effectively eliminate ID/ICs. South Orange County Comprehensive Human Waste Source Reduction Strategy (CHWSRS) Work Plan, Orange County, California, 2019. Mr. Tringali supported technical tasks related to Tetra Tech's development of the CHWSRS Work Plan, which guides stakeholder efforts to reduce pathogen health risk in the South Orange County Watershed Management Area (SOC WMA). Specifically, Mr. Tringali helped to conceptualize a strategy for prioritizing hundreds of stormwater outfall catchment areas based on existing information such as pipe condition, history of sanitary sewer overflows, receiving water impairments, relevant TMDL segments, etc. He also led the development of human waste source investigation strategy which included a "tool box" of indicators (physical, chemical, bacterial, and viral) for tracking potential sources of human waste. A primary focus of the source investigation strategy presented in the Work Plan included leveraging currently available molecular techniques, including droplet digital polymerase chain reaction (PCR) and real-time quantification PCR, to identify and track human biomarkers (i.e., HF183). Mr. Tringali worked with academia to define a set of action levels and triggers applicable at differing phases of a source investigation. The Work Plan was ultimate submitted and approved by the San Diego Regional Water Quality Control Board. Marine Terminal Stormwater Monitoring Program, San Diego Unified Port District, San Diego, CA (2019-Present). Mr. Tringali led development of a strategic stormwater monitoring program that will be used for assessing the effectiveness of the Port's Stormwater Management Program according to effectiveness requirements of the San Diego Water Board's Regional MS4 Permit. The monitoring plan includes multiple sample collection methods (grab, flow -weighted composites, pollutographs) to address a range of objectives. It also includes assessments across multiple temporal (e.g., single storm, seasonal, multi -year) and spatial scales (e.g., catch basin, tenant lease, terminal -wide) that will ultimately drive adaptive management in the direction of the Port's stated goals.
