Abstract:<\/b> Skagit County is the holder of a National Pollutant Discharge Elimination System Phase II Stormwater Permit (NPDES Phase II Permit) issued by the Department of Ecology. The NPDES Phase II Permit is a requirement under the Federal Clean Water Act. The NPDES Stormwater Map is intended to depict known stormwater infrastructure (ditches, culverts, pipes, outfalls, and other structural stormwater BMPs) within the NPDES Phase II Permit area. Skagit County is also involved in an ongoing effort to map all other stormwater infrastructure within its jurisdiction of responsibility. Additional data will be added as it becomes available. <\/div>
