The provisions of this Subpart apply to every AST system that is part of a facility.
(b) Equipment standards for category 2 and 3 AST systems.
In order to prevent releases due to structural failure, corrosion, or spills and overfills, any facility containing a category 2 or 3 AST system must meet the following requirements.
(1) Tanks.
(i) Every AST with a design capacity of 60 gallons or greater must be constructed of steel and must be designed and utilized according to one of the following codes of practice (refer to section 613-1.10 of this Part for complete citation of references), as applicable:
(a) for category 2 ASTs:
(1) UL 142, January 1985;

The classes of petroleum are described in NFPA 30, 2012 edition (refer to section 613-1.10 of this Part for complete citation of references).
Note:
The department recognizes that some petroleum mixtures cannot be safely stored in steel ASTs. A facility owner seeking to store such petroleum mixtures should, pursuant to the provisions of section 613-1.8 of this Part, request a variance from the requirements of subparagraph (i) of this paragraph.
(v) Secondary containment.
(a) Any AST that has a design capacity of 10,000 gallons or more must have secondary containment that meets the following requirements:
(1) be able to contain petroleum leaked from any portion of the AST until it is detected and removed; and
(2) be able to prevent the release of petroleum.
(b) Any AST that has a design capacity of less than 10,000 gallons and is in close proximity to sensitive receptors is required to either have secondary containment as described in clause (a) of this subparagraph or utilize a design/technology such that a release is not reasonably expected to occur. ASTs within 500 horizontal feet of the following resources are considered to be in close proximity to sensitive receptors:
(1) a perennial or intermittent stream;
(2) a public or private well;
(3) a primary or principal aquifer as defined in USGS Water Resource Investigation Reports 87-4274, 87-4275, 87-4276, 87-4122, 88-4076, and Appendix C;
(4) a wetland as defined in Part 664 of this Title;
(5) a lake/pond, estuary, or other similar surface water body; or
(6) a storm drain.
(c) An impermeable barrier under an AST that is in contact with the ground must have a permeability rate to water equal to or less than 1×10-6 cm/sec and must not deteriorate in an underground environment or in the presence of petroleum. All ASTs must be capable of being monitored between the tank bottom and the impermeable barrier.
(d) The secondary containment may consist of a combination of dikes, under-tank liners, pads, ponds, impoundments, curbs, ditches, sumps, tanks used for emergency or overflow containment, or other equipment capable of containing the petroleum stored. Construction of diking and the capacity of the diked area must be in accordance with the following: category 2 AST systems: NFPA 30 (1984 edition), section 2-2.3.3; or category 3 AST systems: NFPA 30 (2012 edition), section 22.11.2.
(e) If soil is used as part of the secondary containment, the soil must be of such character that any spill into the secondary containment will be readily recoverable.
(2) Piping. Piping that routinely contains petroleum and is in contact with the ground must be properly designed, constructed, and protected from corrosion in accordance with subparagraph (i) or (ii) of this paragraph.
(i) Piping made of a non-corrodible material must meet the following conditions.
(a) The materials, joints, and joint adhesives must be compatible with petroleum, petroleum additives, and corrosive soils.
(b) All underground piping must be designed, constructed, and installed with access ports to permit tightness testing without the need for extensive excavation.
(c) All joints must be liquid and air tight.
(d) All underground piping must be tested for tightness before being covered, enclosed or placed in use.

(ii) Piping made of steel that is cathodically protected must meet the following conditions:
(a) The cathodic protection system must provide a minimum of 30 years of protection in corrosive soils.
(b) Cathodic protection must be provided by the use of sacrificial anodes or impressed current.
(c) Where sacrificial anodes or impressed current systems are used, monitors to check on the adequacy of the system must be installed and kept in proper working condition. If at any time the monitor shows that the electrical current necessary to prevent corrosion is not being maintained, the system must be repaired or the piping will be considered unprotected and must be tested for tightness in accordance with section 613-4.3(d)(2) of this Subpart.
(d) Except where cathodic protection is provided by impressed current, underground piping must have dielectric bushings, washers, sleeves, or gaskets installed at the end to electrically isolate the piping from the AST and the dispenser. These dielectric connectors must be compatible with petroleum, petroleum additives, and corrosive soils.
(e) All underground piping must be designed, constructed, and installed with access ports to permit tightness testing without the need for extensive excavation.
(f) All joints must be liquid and air tight.

(6) Every cathodic protection system must be operated and maintained in accordance with section 613-4.2(b) of this Subpart.
(3) Overfill prevention equipment. Every AST must be equipped with a gauge which accurately shows the level of petroleum in the AST. The gauge must be accessible to the carrier and be installed so it can be conveniently read. A high-level warning alarm, a high-level liquid pump cut-off controller, or equivalent device may be used in lieu of a gauge.
(4) Installation.
(i) Every AST system must be supported on a well-drained stable foundation which prevents movement, rolling, or settling of the AST and is designed to minimize corrosion of the tank bottom.
(ii) Prior to first receipt of petroleum, every AST must be tested for tightness. The tank in a category 3 AST system must be tested for tightness and inspected according to one of the following codes of practice (refer to section 613-1.10 of this Part for complete citation of references):

For a valve installed after October 11, 2015, a valve meeting the standards set forth in NFPA 30A (2012 edition), section 6.3.9 meets the requirements of this subparagraph.
(ii) Every dispenser of motor fuel that causes a gravity head must be equipped with a device such as a solenoid valve that is positioned adjacent to and downstream from the operating valve. The valve must be installed and adjusted so that liquid cannot flow by gravity from the AST system in case of piping or dispenser hose failure.
