BMPs 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.
Do I need an NPDES permit?
If you operate a commercial or industrial facility, including wineries, you need coverage under the State Water Resources Control Board's (SWRCB's) Industrial General Permit (IGP). The current version of the IGP became effective on 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.
The NCSPPP collaborated with Napa Valley Vintners to deliver two training events specifically related to wineries' compliance with the new requirements in the IGP.
