Notice of Intent (NOI) Coverage – General Coverage

All industrial facilities that discharge storm water that is associated with industrial activity to the waters of the U.S. are required to file an NOI and meet all requirements of the Industrial General Permit (IGP). Dischargers must apply for coverage under the IGP via the SMARTS website by submitting an NOI certification statement, a SWPPP, and facility site diagrams. An annual permit fee of $1,632.00 must be paid to the state water board.

Filing a Notice of Termination (NOT)

If your facility is closing, moving or no longer needs coverage under the IGP, you must terminate your coverage. A Notice of Termination (NOT) must be submitted via the SMARTS database. Your facility is also required to submit an Annual Report for the period after July 1 that your facility is required to be permitted.

Notice of Non-Applicability (NONA)

Industrial facilities who claim “No Discharge” may apply for a Notice of Non-Applicability (NONA) if they meet the following eligibility requirements:

  • The facility is not hydrologically connected to the waters of the United States.
  • The facility is designed to contain the maximum historic precipitation event (or series of events) of the past 100 year, so that there will be no discharge of industrial stormwater. The National Oceanic and Atmospheric Agency provides historic precipitation data that must be used to make this determination.

If your facility meets the requirements, then a No Discharge Technical Report that demonstrates eligibility must be prepared and signed by a California licensed professional engineer along with the NONA submittal, via the SMARTS database.
