Construction projects disturbing more than the threshold number of acres must obtain

coverage under the State Water Resources Control Board (SWRCB) General Storm Water

Permit to Discharge Storm Water Associated with Construction Activity (General Permit). The

General Permit is issued by the SWRCB and is enforced by the Agency and the Central Valley

coverage or to comply with the requirements of the General Permit could result in significant

daily fines. General Permit coverage is obtained by certifying and filing a Notice of Intent (NOI)

specified otherwise in the Special Provisions. The General Permit also requires inspection of

erosion and sediment control measures before, during, and after storm events.

specified in the Special Provisions, regardless of whether or not the Work is subject to said

permit. The SWPPP shall be prepared by an individual knowledgeable about storm water
