All construction activities that disturb one or more acres are required to maintain a SWPPP that meets the requirements of the AZPDES Construction General Permit.

Once the Arizona SWPPP has been established a Notice of Intent (NOI) is required to be submitted to the Arizona Department of Environmental Quality (ADEQ).

Best Management Practices are required to be in place.

These include but are not limited to:

  • Construction Entrances
  • Silt Fence AZ
  • AZ Straw Wattle
  • Concrete Washout
  • Inlet and Outlet Protection
  • AZ Street Sweeping

    Arizona Stormwater inspections are required to be conducted either every (7) seven calendar days or every (14) fourteen calendar days and whenever it rains .5 inches or more.

    Per the AZPDES Construction general permit these inspections are required to be performed by qualified personnel. ADEQ defines "Qualified Personnel" as personnel knowledgeable in the principles and practice of Arizona erosion control and sediment control BMP's, and who possess the skills and abilities to assess conditions at the site that could impact storm water quality.

    After the construction project is complete and the project's disturbed area is stabilized to at least 70 percent of natural background density or responsibility for the project has been assumed by another operator, a Notice of Termination (NOT) must be submitted to ADEQ to end their participation in the AZPDES Storm Water program.
