The Stormwater Management Act (Act 167) of 1978 (PDF) required that within two years following the promulgation of guidelines by DEP, each county must prepare and adopt a watershed stormwater management plan for each watershed located in the county as designated by DEP, in consultation with the municipalities located within each watershed, and must periodically review and revise such plans at least every five years.
Counties must submit the plans to DEP for approval, and municipalities must enact ordinances or regulations consistent with the plans.
After adoption and approval of a watershed stormwater plan, the location, design and construction of storm water management systems, obstructions, flood control projects, subdivisions and major land developments, highways and transportation facilities, public utility services and facilities owned or financed in whole or in part by funds from the commonwealth within the watershed must be conducted in a manner consistent with the watershed stormwater plan.
For municipalities that have regulated MS4s, compliance with NPDES permits may be achieved by enacting and implementing an ordinance(s) from an applicable Act 167 stormwater management plan if that plan was approved by DEP in 2005 or later.
