Yavapai County operates a Stormwater Management Program (SWMP, updated April 2024) under the AZPDES General Construction Permit AZG2022-001. Construction sites disturbing one acre or more must file a Notice of Intent and maintain a Stormwater Pollution Prevention Plan (SWPPP) covering all phases of work.
Stormwater discharges in Yavapai County are regulated by ADEQ through the AZPDES program rather than directly by the county. The county's Stormwater Management Program (SWMP), updated April 2024, implements federal MS4 requirements in the Prescott/Prescott Valley urbanized area. Construction operators disturbing one acre or more (or under one acre if part of a larger common plan) must submit a Notice of Intent under the General Construction Permit and prepare a site-specific SWPPP. The SWPPP must include erosion and sediment control BMPs, stabilization timelines, and post-construction controls. Illicit discharges - oil, paint, soaps, sediment slurry - into county storm drains are prohibited. The Drainage Design Manual sets engineering standards. The Flood Control District handles plan review.
ADEQ enforcement under AZPDES: civil penalties up to $25,000 per day. County stop-work for non-compliant grading. Illicit discharge to MS4 is separately enforceable.
