Projects include a total maximum daily load (TMDL) stormwater quality monitoring, emerging contaminant monitoring, multiple areas of special biological significance (ASBS) monitoring, an open- and gap-graded asphalt pavements water quality monitoring, and a study on water quality impacts from asphalt concrete grindings. Among these projects, the work includes site reconnaissance and associated reporting; grab sampling in streams, stormwater discharges, and ocean receiving waters; semiautomated sampling station installation and operation; calibration and maintenance of flow meters, autosamplers, and telemetry instrumentation; the installation of water level measuring transducers in streams and performing cross-sectional flow rate measurements to develop stream flow rating curves; leadership for single- and multiple-day stormwater monitoring events; coordination with analytical chemistry and toxicology laboratories; water quality data verification and validation and preparation of electronic data deliverables (EDDs) for upload to the California Environmental Data Exchange Network (CEDEN); and creation of post storm technical memoranda and end-of-season annual reports.

Stormwater Management Improvement Project, Trinidad Head ASBS, Trinidad, California To protect water quality in the Trinidad Head ASBS, the City of Trinidad made significant changes to its stormwater conveyance system in two phases, ultimately eliminating its single stormwater outfall to the ASBS. Led the required environmental monitoring, was coauthor of the project assessment and evaluation plan (PAEP), and was primary author of the water quality monitoring QAPP and water quality monitoring plan. Served as overall project manager and crew leader for all aspects of this 10-year project, including serving as primary client and laboratory contact; providing personnel training; installing a semiautomated sampling station with a flow meter, autosampler, and rain gauge (for flow-based sampling and continuous monitoring of flow and rainfall); conducting grab sampling stormwater discharge and ocean receiving water; conducting subtidal sediment grab sampling from a boat; collecting California mussels for bioaccumulation testing; and ensuring all field sampling activities and laboratory analyses complied with the project QAPP. Handled all the chemistry, toxicity, and tissue data management, data verification, and validation and upload data to CEDEN. Authored a preconstruction and two postconstruction (Phase I and Phase II) sampling and analysis reports that evaluated the amount of pollutant load to the ASBS that was eliminated because of the project (data results included concentrations of conventional constituents, hydrocarbons, nutrients, metals, PAHs and other semivolatile organic compounds [SVOCs], organochlorine and organophosphorus pesticides, PCBs, pyrethroid pesticides, polybrominated diphenyl ethers (PBDEs), and butyltins well as the results from one- and three-species toxicity testing).

Stormwater Pollution Prevention Plans and Consulting Services for Road Construction Projects, Northern California As QSP and WPCM, assisted approximately 20 construction contractors as it pertained to compliance with the California State Water Resources Control Board’s NPDES CGP, Caltrans’ Standard Specifications (Sections 13 and 14), and the project SWPPP or water pollution control program. This compliance assistance included construction site inspections for stormwater best management practices (BMPs), particularly for erosion and sediment control; SWPPP and 401 Permit stormwater sampling and analysis; onsite stormwater BMP and SWPPP training for construction workers; communications with the project manager and site supervisor regarding compliance issues, sometimes involving Caltrans, county, or municipality staff; and reporting for site inspections, sampling, notices of discharge, numeric action level exceedances (for pH or turbidity), and annual reports. Projects have included more than 35 Caltrans, 1 tribal, and 8 county road construction projects, ranging from small to large, the work for which included safety and Americans with Disabilities Act improvements to sidewalks and pedestrian/bike paths and roundabouts, asphalt resurfacing, guardrail and median barriers, road realignments, storm damage repairs, bridge rehabilitation and painting, bridge replacements, rock-fall drapery installations, and large soldier pile ground anchor retaining walls.

Emerging Contaminant Monitoring, Del Norte, Humboldt, Merced, Mendocino, Napa, San Mateo, Santa Barbara, and Santa Cruz Counties, California Served as field lead for this 3-year Caltrans sampling program to characterize concentrations of an emerging contaminant in roadway stormwater discharges into Caltrans’ salmonid fish passage projects. The effectiveness of Caltrans’ approved and pilot BMP treatment control devices was also tested at a subset of locations. Emerging contaminant concentrations were correlated with average annual daily traffic loads and roadway surfaces/geometry that might affect tire wear and the resulting discharges from roadway surfaces.

Stormwater Pollution Prevention Site Assessment Program, California Assisted a large California utility company in determining which water quality protection standards, or BMPs, apply to its operations and service centers; focused on higher-risk pollutants that are comparatively cost effective. Assessed 16 service center hazardous materials business plans. Developed a pre-inspection questionnaire and site inspection form, then performed site inspection visits at several facilities in central and southern service areas; coauthored respective site visit assessment reports. Ranked the operational activities identified by level of risk. Assisted a failure mode and effects analysis based on the results of the service center site surveys to allow an assessment of relative risks between sites and across the portfolio of surveyed sites to identify priorities at each facility while ranking facilities with highest risks. Performed a BMP feasibility study and cost benefit analysis.

Stormwater Pollution Prevention Plan Revision and Implementation, Pittsburg, California Assisted in the evaluation and major revision of an existing SWPPP for compliance with a regional water quality control board (RWQCB) notice of violation (NOV) and a cleanup and abatement order (CAO) for the client’s 8-acre motor vehicle recycling yard. Prior to site inspections, reviewed the San Francisco Bay RWQCB’s NOV and CAO, the facility’s existing SWPPP and stormwater monitoring plan (SWMP), the NPDES General Permit for Discharges of Stormwater Associated with Industrial Activities, and other relevant documentation related to motor vehicle recycling yard BMPs. Prepared a significant revision to the existing SWPPP and SWMP to ensure compliance with the General Permit, NOV, and CAO. Emphasized conveying clearly the regulatory basis and rationale for the document and its readability so that it will be a valuable resource for the facility’s staff.
