TECHNICAL REQUIREMENTS
Section 245.612 - Performance and design standards

(a) Aboveground storage tanks shall be designed, constructed and installed or modified in accordance with current codes of practice developed by Nationally recognized associations 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) Aboveground storage 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 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 aboveground storage tank system.

(d) Aboveground storage 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:

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

(f) Aboveground storage tanks which are internally lined must comply with § 245.534(a) and (b) (relating to interior linings and coatings).

(g) Aboveground storage 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.

(h) Aboveground storage tank systems and storage tank system components whose failure could contribute to a release of product shall be maintained in a good state of repair to ensure they function as designed.
