The final determination updates and renews the General Permit for Discharges from Tanks, Pipes, Other Liquid Containment Structures, Dewatering Activities, and Groundwater Remediation (Maryland General Permit No. 17-HT). The 17-HT permit is effective as of August 1, 2020.
Registrants under the former 11-HT permit have six months (until February 1, 2021) to submit a renewal Notice of Intent (NOI) to have uninterrupted renewal under the 17-HT.
