2020 CGP - Modified
The 2020 Construction General Permit (CGP) was issued on March 27, 2020, and became effective on July 1, 2020, replacing ADEQ’s 2013 CGP. The 2020 CGP was modified to include non-WOTUS-protected surface waters. This modification was necessary in order to incorporate Arizona’s new Surface Water Protection Program (SWPP)1 | Learn More >
The CGP permit modification became effective Sept. 29, 2021. No action is currently required to maintain coverage if you have an active NOI.
