Owners and operators shall maintain release detection records required under § 245.446(2) (relating to release detection recordkeeping) for the most recent 12-month period of active operation.
(d) Subchapter D (relating to corrective action process for owners and operators of storage tanks and storage tank facilities and other responsible parties) shall be complied with if a release is suspected or confirmed.
(e) Inspection requirements at 3-year intervals in § 245.411(c) (relating to inspection frequency) shall be performed on an underground storage tank system in temporary out-of-service status.
(f) When an underground storage tank system is temporarily removed from service for 3 months or more, owners and operators shall also comply with the following requirements:
(1) Vent lines shall be open and functioning.
(2) All other lines, pumps, manways and ancillary equipment shall be capped and secure.
(g) When an underground storage tank system is temporarily removed from service for more than 12 months, owners and operators shall:
(1) Permanently close the underground storage tank system if it does not meet either performance standards in § 245.421 (relating to performance standards for underground storage tank systems) for new underground storage tank systems or the upgrading requirements in § 245.422 (relating to upgrading of existing underground storage tank systems), except that the spill and overfill equipment requirements do not have to be met.
(2) Permanently close the substandard underground storage tank system at the end of this 12-month period in accordance with §§ 245.452—245.455, unless the Department provides an extension of the 12-month temporary out-of-service period.

The required assessment of the excavation zone under § 245.453 (relating to assessing the site at closure or change-in-service) shall be performed after notifying the Department but before completion of the permanent closure or a change-in-service.
(b) To permanently close a tank, owners and operators shall ensure that the tank is empty and clean in accordance with a Nationally recognized code of practice by removing the liquids and accumulated sludges. Tanks being permanently closed shall also be either removed from the ground or filled with a nonshrinking, inert solid material.
(c) Replacement, removal or closure-in-place of underground product piping or remote fill lines connected to a storage tank shall be considered a permanent closure of that part of the underground storage tank system. A major modification to the dispenser involving excavation beneath the dispenser and removal of the dispenser shall also be considered permanent closure of that part of the tank system. The requirements applicable to permanent closure of an underground storage tank system also apply to the permanent closure of system piping, remote fill lines, and dispensers.
