How and by whom is the Stormwater Regulatory Program implemented in Arizona?
On December 2002, Arizona received authorization from EPA to operate the National Pollutant Discharge Elimination System (NPDES) Permit Program (Section 402 of the Clean Water Act) at the state level, or more specifically, under the Arizona Pollutant Discharge Elimination System (AZPDES) program. The Arizona Department of Environmental Quality (ADEQ) is the only state agency with the authority to administer the AZPDES permit program in Arizona. Under AZPDES, all regulated activities that discharge pollutants, including construction, are required to obtain or seek coverage under an individual or general permit.
