San Joaquin County operates under a Phase II MS4 NPDES permit from the Central Valley Regional Water Board. Construction disturbing 1+ acre needs a SWPPP and coverage under the CGP. Priority Development Projects creating 2,500+ sq ft of impervious area need post-construction stormwater treatment. Illicit discharge to storm drains and Delta sloughs is strictly prohibited.
San Joaquin County regulates stormwater under the California General Construction NPDES Permit and its own Phase II Municipal Separate Storm Sewer System (MS4) permit issued by the Central Valley Regional Water Quality Control Board. Any land-disturbing activity of 1 acre or more (or less if part of a larger common plan of development) requires a Stormwater Pollution Prevention Plan (SWPPP), electronic filing through the SMARTS system, a Qualified SWPPP Developer/Practitioner, and a Notice of Intent. Post-construction stormwater management applies to Priority Development Projects that create or replace 2,500 square feet or more of impervious surface in specified categories — these must include Low Impact Development (LID) features: bioretention cells, vegetated swales, pervious pavers, underground retention, and treatment-train BMPs designed to capture the 85th-percentile storm. Owners must record a stormwater facilities operation and maintenance agreement. Illicit non-stormwater discharge (washing concrete, dumping chlorinated pool water, oil, soap, paint) into storm drains or directly to Delta sloughs, the San Joaquin River, the Mokelumne, or the Calaveras Rivers is strictly prohibited and carries significant fines. Agricultural discharges fall under the Irrigated Lands Regulatory Program (ILRP) through coalition groups (e.g., San Joaquin County & Delta Water Quality Coalition).
SWPPP non-compliance on active construction site: Regional Board penalties $500–$10,000 per day per violation (Water Code §13385). Illicit discharge to storm drain: $1,000–$25,000 per incident + cleanup costs + potential criminal referral. LID bypass on PDP: permit hold until remediation.
