§ 245.452. Permanent closure and changes-in-service.

 (a)  At least 30 days before beginning either permanent closure or a change-in-service under subsections (b)—(d), or within another reasonable time determined by the Department, owners and operators shall notify the Department on a form provided by the Department of their intent to permanently close or make the change-in-service, unless the action is in response to corrective action. 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.

 (d)  Before a change-in-service, owners and operators shall ensure that the tank is empty and clean in accordance with a Nationally recognized code of practice by removing the liquid and accumulated sludge, and conduct a site assessment in accordance with §  245.453.

 (e)  The owner shall complete and submit an amended tank registration form, signed by the owner and the certified installer that provided direct onsite supervision of the tank handling activity, to the Department within 30 days of either of the following:

   (1)  The completion of permanent closure.

   (2)  Change-in-service of the tank.

 (f)  A properly completed closure report is required to permanently close a site, including a change-in-service. A copy of the completed closure report shall be submitted to the Department when requested.
