Section 245.612. Performance and design standards

(a) Tanks shall be designed, constructed and installed or modified in accordance with current codes of practice developed by Nationally-recognized associations such as API, ASME, ASTM, ANSI, STI and UL and the manufacturer’s specifications. Tank handling activities shall be accomplished by a Department-certified aboveground storage tank installer or under the installer’s direct, onsite supervision and control.

(b) Tanks must have a stable support or foundation capable of adequately supporting the total weight of the tank and its contents when in use. The support or foundation must meet or exceed the specifications of the tank manufacturer and be designed and constructed in accordance with sound engineering practices.

(c) Ancillary equipment, including piping, shall be designed, installed and modified in accordance with current codes of practice developed by Nationally-recognized associations such as API, SSPC, NACE, ASME, PEI and UL and the manufacturer’s specifications. Ancillary equipment must be compatible with the substance stored and must be adequately protected from corrosion, excessive wear and deterioration. Protective coatings shall be maintained throughout the entire operational life of the storage tank system.

(d) Tanks shall be installed with secondary containment in or under the tank bottom to provide monitoring capability to satisfy leak detection requirements in § 245.613 (relating to monitoring standards) and emergency containment to contain possible releases, such as overfills, leaks and spills. Emergency containment must be sufficiently impermeable to contain any potential release for a minimum of 72 hours and until the release can be detected and fully recovered in an expeditious manner. Double walled tanks may meet both emergency and secondary containment requirements when the tank system is operated with spill and overfill protection controls including the following:

(1) A spill containment bucket at the tank fill point or containment at the remote fill point.

(2) An overfill alarm or prevention device or monitoring gauge and shut down procedure.

(3) Block valves on product lines.

(4) Solenoid valve or antisiphon device, if appropriate (See PEI RP 200).

(e) Existing tanks which do not meet the requirements specified in subsection (d) shall be upgraded with secondary containment by October 11, 2007, and emergency containment by October 11, 2000.

(f) Tanks installed in underground vaults after October 11, 1997, and used for dispensing Class I and Class II motor fuels must comply with § 245.523 (relating to aboveground storage tanks in underground vaults).

(g) The exterior of the tank system shall be protected by an appropriate coating or paint which shall be maintained throughout the entire operational life of the tank system.

(h) Tanks which are internally lined must comply with § 245.534 (relating to interior linings and coatings).

(i) Tanks shall be labeled or marked in a manner consistent with industry standards and which provides for identifying the regulated substance stored from outside the containment area.
