NPDES General Permits for Marinas, and Mining Activities: If you did not fill the on-line renewal request form last year, please contact us directly to request renewal.
UPDATE: The new NCG20 (Scrap Metal) permit was issued February 2, 2015. We sent electronic COC renewal instructions and PINs to those permittees on 2/23 (unless paper package requested or fees were overdue). Here is a list of which COCs have been accessed.
The NCG02 (Mining) and NCG19 (Marinas) permits were reissued the same day for another four months with no changes; permittees must access the revised cover sheet from our website (new COCs will not be sent). We will contact permittees about futher permitting actions in June 2015.
The following list is provided for informational purposes only and accurate as of the date of posting:

NPDES Stormwater Program
The National Pollutant Discharge Elimination System (NPDES) stormwater permitting program regulates three types of activities: Industrial activities that fall in one of 10 categories; Municipal Separate Storm Sewer Systems (MS4s); and Construction activities that disturb an acre or more.
State Stormwater Programs
The State Stormwater Permitting Programs regulate site development and post-construction stormwater runoff control. Areas subject to these permit programs include all 20 coastal counties, and various other counties and watersheds throughout the state. Areas subject can be found using the Interactive Stormwater Permitting Map Viewer. What does Phase II have to do with State Stormwater?
