Stormwater Inspections
California's Construction General Permit (CGP) Order 2022-0057-DWQ is one of the most stringent in the nation, administered by the State Water Resources Control Board. The permit uses a risk-based approach with three tiers that determine monitoring, reporting, and BMP requirements. Sites with higher risk levels face numeric effluent limitations for turbidity and pH, and may require active treatment systems.
