MS4 Presentation about Storm Water Permit requirements

What is MS4?

Under the 1987 Clean Water Act Amendments, the U.S. EPA developed new stormwater regulations to address storm water that might impact water quality.  These new regulations were set up in two Phases depending upon population.  Phase I, which affected municipalities with 100,000 or more in population that did not have combined sewers included Allentown and Philadelphia.  Phase II of the regulation affected about 1,000 additional municipalities in Pennsylvania.  Those municipalities that are located within and “urbanized area” as defined by the 1990 Census and the 2000 Census were required to apply for a National Pollutant Discharge Eliminations System (NPDES) permit to discharge stormwater from their municipal separate storm sewer system (MS4). Many municipalities in Berks County are included in this Phase II NPDES Permitting.
