Section 245.522 - New aboveground storage tank installations and reconstructions(a) Aboveground storage tanks shall be designed and constructed in accordance with an appropriate current code of practice developed by Nationally recognized associations such as UL, ACI, API, ASME, ASTM, STI or NACE and will follow applicable engineering specifications.(b) Aboveground storage tanks must have a stable foundation, capable of supporting the total weight of the tank when full of product without movement, rolling or unacceptable settling. The foundation must minimize corrosion of the tank bottom and meet or exceed the specifications of the tank manufacturer. The foundation design and construction must be based on sound engineering practices.(c) Aboveground storage tanks shall be tested for tightness in accordance with current codes of practice developed by Nationally recognized associations and manufacturer's specifications. If a pneumatic test is used for manufactured (shop built) tanks, the fittings, welds, joints and connections shall be coated with a soap solution and checked for leaks. Aboveground field constructed storage tanks shall be hydrostatically tested. Deficiencies shall be remedied prior to tanks being placed into service. Hydrostatic test fluids shall be discharged or disposed of in accordance with State and Federal requirements.(d) Reconstruction of aboveground storage tanks must follow the current codes of practice developed by Nationally recognized associations and be accomplished in accordance with sound engineering practices. Reconstructed aboveground storage tanks must be inspected and hydrostatically tested before being placed into service. Reconstructed aboveground storage tanks must meet or exceed requirements specified in § 245.521 (relating to performance standards for aboveground storage tanks). Hydrostatic test fluids shall be discharged or disposed of in accordance with State and Federal requirements.(e) Aboveground manufactured storage tanks that are relocated to another service site must meet the performance requirements for aboveground storage tanks and shall be tested according to industry standards and inspected before being put back in service.(f) The Department may require the tank owner to submit documentation of construction design criteria and engineering specifications for review.The provisions of this § 245.522 amended November 9, 2007, effective 11/10/2007, 37 Pa.B. 5979; amended December 21, 2018, effective 12/22/2018, 48 Pa.B. 7875.
