Underground Storage Tank Remediation General Permit

Facilities that receive coverage under Mississippi’s Underground Storage Tank Groundwater Remediation General Permit (UST General Permit) may discharge remediated groundwater associated with leaking underground storage tanks into waters of the State, a local Publicly Owned Treatment Works (POTW) or Wastewater Collection Authority collection and/or treatment systems with capacities of 0.010 Million Gallons per Day (MGD) or more. This Underground Storage Tank Groundwater Remediation General Permit (UST General Permit) covers new and existing remediated groundwater discharges associated with leaking USTs. Remediated groundwater discharges that enter waters of the State, POTWs or Wastewater Collection Authorities are subject to regulation and compliance with the conditions set forth in this permit. This permit may also authorize the discharge of remediated groundwater from facilities specifically designated by the Executive Director. This permit replaces the previous UST Groundwater Remediation General Permit that expired on June 30, 2016.
