municipal separate storm sewer system

HB 2272 allows Arizona counties operating municipal storm sewer systems to develop local stormwater programs that meet federal Clean Water Act requirements. It permits counties to charge fees only for permit administration (not infrastructure costs) and prohibits them from creating rules stricter than federal standards. The bill specifically affects counties with stormwater systems discharging into protected waters, requiring them to align local programs with federal public education and outreach requirements. Counties must also publicly share new stormwater regulations before adoption, including posting them online and filing summaries with the Secretary of State.
