Municipal Stormwater Regulation Program

The Municipal Stormwater Regulation Program was developed in response to the U. S. Environmental Protection Agency’s (USEPA) Phase II rules published in December 1999.  The Department issued final stormwater rules on February 2, 2004 and four (4) NJPDES general permits authorizing stormwater discharges from Tier A and Tier B municipalities, as well as public complexes, and highway agencies that discharge stormwater from municipal separate storm sewers (MS4s).  Public complexes include certain large public colleges, prisons, hospital complexes and military bases.  Highway Agencies include county, state, interstate, or federal government agencies that operate highways and other thoroughfares.

The general permits address stormwater quality issues related to new development, redevelopment and existing development by requiring regulated entities to implement Statewide Basic Requirements (SBRs).

Municipal Stormwater Permit Status
The Department has issued the final renewal permits for Tier A and B municipalities on November 9, 2017 and will become effective January 1, 2018. Two of the four Municipal General Permits have expiration dates of February 28, 2014. However, these permits will remain in full force and effect until renewal permits are issued. Until then, continued implementation of all aspects of your Public Complex or Highway General Permit(s) is required. You will be notified once draft permits are available and have the opportunity to comment on any proposed changes at that time. If you have any specific questions on the renewal process or the recent renewal of the Tier A and Tier B MS4 General Permit(s), please contact your case manager or you may email, The Department appreciates your continued cooperation in this matter.
