Compton, CA Environmental Rules: Erosion Control (2026)

9, part of the Chapter 31 Runoff Pollution Control ordinance adopted under Ordinance No. 2047, ties the city's grading-permit process directly to state erosion-control permitting. Subsection (a) bars the City from granting a grading permit or allowing construction activity that disturbs five acres or more of soil through clearing, grading, or excavation "without demonstrating to the City that such person has obtained a NPDES General Construction Activity Storm Water Permit" issued by the State Water Resources Control Board (SWRCB). Subsection (b) requires anyone conducting construction subject to that permit to keep several documents on site: the Notice of Intent to comply with the general construction permit, the SWRCB-issued waste discharge identification number, a Storm Water Pollution Prevention Plan (SWPPP) and monitoring program plan, and records of inspections and good-housekeeping compliance.

Subsection (c) requires the contractor to produce those documents on request from a City officer and to retain them for at least three years after construction is complete. 10 separately requires any construction activity subject to the municipal NPDES permit to implement best management practices specified by the Regional Board, its Executive Officer, or the City's Public Works Director, layering city-level BMP enforcement on top of the state permit requirement. Together these sections make erosion and sediment control on qualifying construction sites a joint state-permit-and-local-recordkeeping obligation rather than a city-issued erosion permit of its own.
