From 2004 to 2014, CASC provided subcontracted professional and technical on-call stormwater quality assurance services to assist Caltrans, the Country’s largest Transportation Department, in achieving compliance with the NPDES permit obligations at construction sites and maintenance facilities. The program is intended to help the State’s construction and maintenance managers know if storm water BMPs are being implemented as intended, and to support efforts to evaluate, define, and revise storm water management practices.

Inspections: Our field staff provided inspections and reports in support of compliance monitoring of construction activities, maintenance activities, operating right-of-way, and other transportation facilities (e.g., maintenance stations, roadside rest areas, and Department properties leased to others). Our field staff assisted Caltrans with storm water compliance inspections at construction sites. They evaluated the compliance of selected construction projects statewide against the requirements of the permit, Water Pollution Control Program (WPCP) and the approved Storm Water Pollution Prevention Plan (SWPPP).

CASC inspected construction projects and facilities for proper selection, installation, and maintenance of Best Management Practices (BMP’s). We inspected thousands of sites throughout the state with most of our duties covering Southern California and the Los Angeles Metro region. We provided additional related services as deemed appropriate by the Department.

Storm Water Documents: CASC’s duties included the review and evaluation of storm water documentation relevant to the activities or facilities inspected. These documents included the Water Pollution Control Plan (WPCP), the Storm Water Pollution Prevention Plan (SWPPP), and Facility Pollution Prevention Plan (FPPP). We coordinated with the State’s representatives (e.g., Resident Engineers, Maintenance Supervisors, and Storm Water Coordinators) in regard to evaluation of storm water activities or compliance documents. Coordination activities included arrangement of access, discussion of findings and recommendations, and preparation of reports.


Our field staff reported compliance status to Department management. Our staff also performed Construction Compliance Evaluation Plan (CCEP) and Annual Maintenance Facility Compliance Review Plan (AMFCRP) reviews in various districts by evaluating construction and maintenance facility storm water compliance with the Construction General Permit, Caltrans Permit, Caltrans guidance documents and the construction storm water program. Reports were generated using the Access database for ACCRP, maintenance facility and Maintenance activity inspections.  CCEP inspections were entered into the Contractor Purchasing System Review (CPSR) tool.  After the reports are generated they converted to PDF files and uploaded with photos to the Project Solve “eRoom” (a web-based storage system).
