The NPDES Tier II General Permit covers small municipal storm water sewer systems (MS4s) located in the State of Delaware that are within Urbanized Areas as defined by the US Census Bureau and those that may be designated by the Department. Entities within Urbanized Areas not otherwise covered by a MS4 General Permit may request a waiver. Only small Phase II MS4s that submit a Notice of Intent (NOI) and a Storm Water Management Program Plan in accordance with the terms and conditions of this proposed National Pollutant Discharge Elimination System (NPDES) Permit No. DE 0051217 (State Number WPCC 3033/20) and obtain written authorization from DNREC will be authorized under the Tier II General Permit to discharge storm water to the waters of the State of Delaware. The permit available for review contains additions and modifications that include the MS4 designation criteria and a process to ensure all urbanized areas are addressed for permit coverage.

This General Permit is in compliance with the provisions of the Federal Water Pollution Control Act, as amended by the Clean Water Act of 1977 and the Water Quality Act of 1987 (33 U.S.C.§§ 1251 et seq.) and pursuant to the provisions of Title 7, Del. C., § 6003.
