What is an NOI and what permits does it cover?
An NOI is a “Notice of Intent’ application to be included in one of CA’s General Stormwater Discharge Permits. If you are a commercial or industrial facility covered by certain NAIC code like chemical manufacturing or vehicle servicing, you may be required to file an NOI for inclusion in CA’s General Permit for Industrial Facilities. If you disturb soil of more than 1 acre you may be required to file an NOI for inclusion in CA’s General Construction permit. If you are a point source discharger like an industrial facility you may be required to apply for an individual NPDES permit. If you are a municipality that owns/maintains an MS4 you may be required to apply for a Municipal Stormwater Discharge NPDES permit.
