Section 613-4.5 - Out-of-service AST systems and closure

(a)Out-of-service AST systems.

(1) An AST system is out of service if:

(i) the facility owner (or their authorized representative) takes the tank system out of service by submitting an application to the Department, in accordance with subparagraph 1.9(c)(4)(ii) of this Part, indicating that the tank system is out of service; or

(ii) the tank system is no longer receiving or dispensing petroleum. Within 30 days after the tank system no longer receives or dispenses petroleum, the facility owner (or their authorized representative) must submit an application to the Department, in accordance with subparagraph 1.9(c)(4)(ii) of this Part, indicating that the tank system is out of service.

(2) Out-of-service AST systems are still subject to all applicable requirements of this Part, with the exception of periodic operation and maintenance walkthrough inspections and leak detection required under subdivisions 4.2(h), and 4.3(a) and (b) of this Part, respectively, if the AST system is empty. (An AST system is considered empty when all petroleum has been removed using commonly employed practices so that no more than 2.5 centimeters (one inch) of residue remain in the AST system.)

(i) The suspended requirements of subdivisions 4.2(h), and 4.3(a) and (b) of this Subpart must resume in accordance with the original schedule when the AST system is returned to service. However, if the AST system has been out of service such that any of the next periodic testing/monitoring/inspections was not conducted in accordance with the original schedule, the testing/monitoring/inspection must be performed when the AST system is returned to service.

(ii) For AST system taken out of service due to repairs (in response to a leak), the repair and subsequent testing requirements of subparagraph 4.2(j) of this Subpart must be successfully completed before the AST system is returned to service.

(3) When an AST system is out of service for more than 90 days, or has not received or dispensed petroleum in a 90-day period, the following must also be performed:

(i) empty the tank so that no more than 2.5 centimeters (one inch) of residue remains;

(ii) leave vent lines open and functioning; and

(iii) cap and secure all piping, fill ports, gauge openings, vapor returns, pump connections, ancillary equipment, and manways.

(4) When an AST system is out of service for more than 12 months, or has not received or dispensed petroleum in a 12-month period, the AST system must be permanently closed in accordance with subdivision (b) of this section, unless the AST system is located at a facility where one or more other tank systems are in-service.

(b)Permanent closure.

(1) At least 30 days before permanent closure, the facility owner (or their authorized representative) must notify the Department of this action, unless such action is in response to corrective action in accordance with Subpart 7 of this Part.

(2) Within 30 days after permanent closure, the facility owner (or their authorized representative) must submit an application to the Department, in accordance with subparagraph 1.9(c)(7)(ii) of this Part, indicating that the AST system has been permanently closed.

(3) All scheduled deliveries to AST systems that have undergone permanent closure, must be terminated.

(4)Methods of permanent closure.

(i) To perform a tank removal, all liquids and accumulated sludge must be removed from the tank system prior to removing the tank from the ground. All lines (including delivery piping) must be either disconnected and removed, or securely capped or plugged. One of the following codes of practice (refer to section 1.10 of this Part for complete citation of references) must be adhered to in order to comply with this paragraph:

(a) PEI RP 1700, 2018 edition; or

(b) a code of practice developed by a nationally recognized association or independent testing laboratory and approved by the Department.

(ii) To perform an in-place closure, all liquids, accumulated sludge, and petroleum vapors must be removed from the tank system prior to stenciling the tank with the date of permanent closure. The tank must be protected from flotation. All lines (including delivery piping) must be either disconnected and removed, or securely capped or plugged, and all manways must be securely fastened in place. One of the following codes of practice (refer to section 1.10 of this Part for complete citation of references) must be adhered to in order to comply with this paragraph:

(a) PEI RP 1700, 2018 edition; or

(b) a code of practice developed by a nationally recognized association of independent testing laboratory and approved by the Department.

(iii) To perform a change-in-service, all liquids, accumulated sludge, and petroleum vapors must be removed from the tank system prior to changing the stored substance. One of the following codes of practice (refer to section 1.10 of this Part for complete citation of references) must be adhered to in order to comply with this paragraph:

(a) API RP 2015, August 2001;

(b) API RP 2016, August 2001;

(c) NFPA 326, 2010 edition; or

(d) a code of practice developed by a nationally recognized association or independent testing laboratory and approved by the Department.

(5) AST systems that have been permanently closed may not be returned to service unless all components of the AST system meet applicable requirements for the latest Category.

(c)Recordkeeping. Records required by this section must be retained for three years after permanent closure, or until the facility has been permanently closed, whichever is later. Copies of these records must also be submitted to the Department within 30 days after permanent closure and must consist of a report detailing that the tank was permanently closed in accordance with subparagraph (b)(4)(i), (ii), or (iii) of this section.
