The discharge of pollutants into storm drains and creeks is prohibited by federal, State and local regulations. Furthermore, the NCSPPP municipalities are required, under the Phase II Municipal Stormwater National Pollutant Discharge Elimination System (NPDES) Permit, to enforce their local stormwater ordinances.
Best Management Practices may include the scheduling of activities, prohibition of practices, maintenance procedures or other practices used to prevent or reduce the discharge or pollutants, directly or indirectly, to stormwater, storm drains or receiving waters. BMPs may be categorized as either structural or operational. Structural BMPs are generally the most effective. Covers and designated wash areas are good examples of structural BMPs. Operational BMPs can be just as effective as structural BMPs, but an effective employee training program and diligence is required to prevent an illicit discharge.
If you operate a commercial or industrial facility, including wineries, you need coverage under the SWRCB's Industrial General Permit (IGP). The current version of the IGP is effective through June 30, 2015. Starting July 1, 2015 industrial and commercial dischargers will be subject to the new IGP which includes a number of new requirements.
