Regulation .04 Performance Standards for a Field-Erected AST System.LinkCopy Citation
An owner, an operator, and a person in charge of an AST system with a field-erected AST shall:
A.
Ensure the field-erected AST is:
(1)
Properly designed for the oil storage application and type of oil to be stored;
(2)
Constructed of welded carbon steel or stainless steel; and
(3)
Constructed to an industry standard, including an API standard for field-erected ASTs incorporated by reference in COMAR 26.10.01.03;
B.
Ensure the foundation of the field-erected AST:
(1)
Is designed and constructed in accordance with Annexes B and I of API Standard 650 “Welded Tanks for Oil Storage” to prevent settlement of the foundation and the AST due to soil bearing capacity and other site conditions using:
(a)
Field and laboratory testing; and
(b)
Analyses and other sound engineering practices performed by a professional engineer;
(2)
Is capable of supporting the load of the AST and its contents without excessive differential settlement; and
(3)
Provides positive drainage of water away from the AST base; and
C.
Test a new, repaired, or relocated AST system for tightness in accordance with NFPA 30 “Flammable and Combustible Liquids Code”:
(1)
Upon completion of the installation or repair of the AST system; and
(2)
Before placing the AST system in-service
