Comparison: State vs. Federal
· Rules. Alaska is authorized by the U.S. Environmental Protection Agency (EPA) to administer the federal National Pollutant Discharge Elimination System (NPDES) permit program, known as the Alaska Pollutant Discharge Elimination System (APDES) program in the state, for wastewater discharges, including permitting authority for stormwater discharges associated with municipal separate storm sewer systems (MS4s). The state generally follows the federal rules for NPDES stormwater permits See the national section STORMWATER—MUNICIPALITIES for more information on the federal MS4 permitting program.
· Administration and enforcement.In Alaska, the DEC’s Division of Water Quality is responsible for administering the stormwater MS4 permitting program.
Under the NPDES stormwater program, operators of large, medium, and regulated small MS4s require authorization to discharge pollutants under an NPDES permit. Regulated small MS4s are defined as all small MS4s located in "urbanized areas" (UAs) as defined by the Bureau of the Census, and those small MS4s located outside of a UA that are designated by NPDES permitting authorities.
In Alaska, the Bureau of the Census recognizes only Anchorage and Fairbanks as urbanized areas; these areas are covered by an MS4 stormwater permit.
