The Town of Paradise Valley's Storm Water Management Plan was updated in June 2015. A Storm Water Management Plan is required to satisfy the National Pollution Discharge Elimination System (NPDES) Phase II Regulations.
The U.S. Environmental Protection Agency (EPA) published the final NPDES Phase II Storm Water Regulations on December 8, 1999. The Town is required to submit its plan to comply with the Arizona Department of Environmental Quality which enforces the NPDES. The Town filed its Notice of Intent for Coverage for discharges from small MS4s (Municipal Separate Storm Sewer System. This is different from a combined sanitary and storm sewer system) to waters of the United States in April 2008.
STormwater Outreach for Regional Municipalities (STORM) promotes stormwater quality and pollution prevention education within the greater Phoenix metropolitan area.
The Arizona Department of Environmental Quality (ADEQ) was established in 1986 in response to growing concerns over groundwater quality. The Department administers a variety of programs to improve the health of Arizonans and ensure the quality of Arizona's air, land, and water resources.
