|Storm water discharges are generated by runoff from land and impervious areas such as paved streets, parking lots, and building rooftops during rainfall and snow events that often contain pollutants in quantities that could adversely affect water quality. Most storm water discharges are considered point sources and require coverage by a National Pollutant Discharge Elimination System (NPDES) permit. The primary method to control storm water discharges is through the use of structural and nonstructural Best Management Practices.
A 1987 amendment to the federal Clean Water Act required implementation of a two-phase comprehensive national program to address storm water runoff. Phase I focused on large construction sites, 11 categories of industrial facilities, and major metropolitan Municipal Separate Storm Sewer Systems (MS4s).
Phase II is the next step in an effort to preserve, protect and improve water resources impacted by storm water runoff. The program has broadened to include smaller construction sites, small municipalities (populations of less than 100,000) that were temporarily exempted based on their industrial activity, and Small Municipal Separate Storm Sewer Systems (MS4s). Phase II is designed to further reduce adverse impacts to water quality, and it places controls on runoff that have the greatest likelihood of causing continued environmental degradation. The City of Grand Forks was designated as a MS4 under the Phase II program and was required to develop a Storm Water Pollution Prevention Program by March 10, 2003.
The storm water regulations are part of the NPDES permit program. The U.S. Environmental Protection Agency (EPA) delegated permitting authority for Dakota's program to the North Dakota Department of Health (NDDH). The three permit types: construction, industrial, and MS4 each have distinct requirements.
Please notify the City's Environmental Compliance Officer at 738-8781 if you see any of the following pollutants being put in the storm drain: motor oil, oil filters, antifreeze, transmission fluids, pet waste, yard waste, dirt or gravel, trash, construction debris, paint, solvent/degreaser, cooking grease, detergent, home improvement waste, pesticides, or fertilizers.
