DelDOT is a co-permittee with New Castle County on a Phase I National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permit. As part of the permit conditions, the Stormwater Pollution Prevention and Management Plan includes a street sweeping requirement to reduce pollutant loads from roadways to improve water quality. To meet permit requirements, DelDOT devised a targeted sweeping plan, which provides the most cost effective routes to reduce the greatest amount of pollutants. In general, interstates and expressways are swept 8 times per year, arterials are swept either 3 or 8 times per year depending on the average daily traffic, collectors are swept 3 times per year, and local roads swept 1 time per year within the permitted area. <\/SPAN><\/P>

Purpose: The Street Sweeping Plan helps DelDOT fulfill NPDES requirements. <\/SPAN><\/P>
