Hummelstown Borough implements the National Pollutant Discharge Elimination System (NPDES) Permit for our
Municipal Separate Storm Sewer System (MS4) as part of the Federal Phase II Stormwater Management Program.

General NPDES Permit and has been issued NPDES Permit No. PAG133556, Authorization ID No. 942099.
