Final Determination 

The Department has made a final determination to issue this general permit.  Beginning on July 15, 2020, the Department will publish notice of the final permit determination in newspapers around the state.  The Department is also publishing notice of the final determination in the Maryland Register on July 17, 2020.  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.  So long as a timely NOI is submitted, coverage shall continue under the 11-HT until the Department issues registration under the 17-HT.

The 17-HT permit does not provide coverage for oil terminals.  Oil terminals must obtain a discharge permit through the Department's Oil Control Program.
