New Jersey Stormwater Management Rules at N.J.A.C. 7:8 set uniform statewide design and water-quality standards that municipalities must adopt by ordinance, preventing cities from weakening these baseline requirements.
Under the Stormwater Management Act and N.J.A.C. 7:8, the Department of Environmental Protection sets uniform standards for major development, including groundwater recharge, runoff quantity, and water-quality treatment. Every NJ municipality must adopt a model stormwater control ordinance and a Municipal Stormwater Pollution Prevention Plan as conditions of its NJPDES Tier A or Tier B MS4 permit. Local rules can be more protective but cannot fall below state minimums for green infrastructure and pollutant removal.
Failure to comply can result in DEP penalties, NJPDES permit enforcement, project stop-work orders, and required retrofits.
