More Information

To simplify implementation of the new Arizona Surface Water Protection Program (SWPP), ADEQ will modify the existing AZPDES General Permits (GPs) to extend coverage to state-listed waters. Our goal is to have the modified permits finalized by mid-August. 

Permits to be modified include:

  • Construction General Permit (CGP)
  • Multi Sector General Permit (MSGP)
  • Mining Multi Sector General Permit (Mining MSGP)
  • De Minimis General Permit (DMGP)
  • Phase II MS4 General Permit (MS4 GP)
  • Pesticides General Permit (PGP)

No other general permit conditions or requirements are changing with the exception of the small MS4 general permit, which is currently being revised as part of reissuance and will be included in this public comment period.

Application for a permit under the modified GP will not change; the myDEQ process will remain the same. Also, existing permit holders will not need to apply for a new permit.
