Since 2007, CASC has provided on-call construction site NPDES compliance services to Southern California Edison (SCE) in support of their unprecedented $20 Billion infrastructure improvement program. SCE, a subsidiary of Edison International, is California’s largest investor-owned utility.

Our team has provided storm water quality assurance services at new substations, hundreds of miles of new transmission lines, port facilities, substations, and power relocation projects associated with Caltrans highway widening projects. Projects cover a large geographic range, from the Port of Long Beach and other highly urbanized areas, to the deserts and mountains of Southern California, to the Cental Valley and the Colorado River.

CASC staff monitor the implementation and enforcement of various NPDES permit requirements such documentation, BMP implementation, waste discharge requirements, and associated monitoring and reporting requirements.

Our compliance monitoring team includes field staff conducting inspections, and office staff processing storm water documents including; Operational Storm Water Management Plans (O-SWMPs), SWPPPs, and Five Year Maintenance Plans (FYMPs).

The field inspection team consists of 4 to 6 full-time inspectors and additional part-time support as needed. The inspectors have used a variety of electronic field reporting applications over the years. The most current application in use is the web-based SWPPP Mobile App, which documents each project, allowing our inspectors to identify, assign, track, and report observations using an iPad.  Our field inspectors provide electronic copies of all correspondence and reports and include them in the project files and database.

Our work covers the entire SCE service area, from the Ports of Long Beach and Los Angeles, to the I-5 corridor widening project from the Renewable Energy projects in the desert regions, to the new transmission projects in the Central Valley and Central Coast.
