Stormwater regulations apply to construction sites, industrial facilities and municipalities such as the City of Mesa. The City of Mesa operates under a Municipal Stormwater Permit issued by the Arizona Department of Environmental Quality effective August 30, 2010. This permit requires the City to develop a Storm Water Management Plan (SWMP) identifying various best management practices (BMPs) to be implemented to reduce stormwater pollutants.
Examples of BMPs are conducting household hazardous waste collection events, inspecting retention basins for pollutants, disseminating public education materials and screening stormwater discharge points for pollutants.
The Municipal Stormwater Permit also requires the City to develop and enforce an ordinance that prohibits the discharge of polluntants to the City's storm drain system and to post a copy of the City's SWMP and the most recent annual report on the City's website.
