October 13, 2016 - On September 29, 2016, the Arizona Department of Environmental Quality (the "ADEQ") re-issued the Small MS4 Stormwater General Permit, AZG2016-002 (the "Permit") to provide coverage to existing and new MS4s for the discharge of stormwater to waters of the U.S. within Arizona. Key updates include:
- Existing permittees must update their Stormwater Management Program within six months of the Permit's effective date; and, new permittees have one year from the effective date to establish a Stormwater Management Program.
- All permittees must have enforcement authority. This may require a permittee to implement and/or amend its current codes and ordinances, and establish an enforcement response plan.
- Existing and new permittees are automatically covered under the Permit for up to 180 days from September 30, 2016. To maintain coverage the permittee must complete and submit a Notice of Intent ("NOI") within 180 days of September 30, 2016. A NOI is subject to public comment.
- Existing permittees have 12 months to update their storm sewer system map showing the locations of all outfalls and the names and locations of all waters of the U.S. that receive discharges from those outfalls. New permittees must include a mapping schedule with their NOI and must complete their mapping by the end of year four of the Permit term.
- Existing permittees will be billed in accordance with their current annual billing cycle. New permittees must submit the appropriate fee with their NOI. (See A.A.C R18-14-109).
