CHECKING ANG TESTINGCHECKING ANG TESTINGTesting Requirements for Tanks. Initial Testing. Initial Testing. All tanks, whether shop built or field erected, shall be tested before they

are placed in service in accordance with the applicable requirements of the code under which

they were built.

An approved listing mark on a tank shall be considered to be evidence of compliance

with this requirement. Tanks not marked in accordance with this subsection shall be tested before

they are placed in service in accordance with good engineering principles.

Tightness Testing. In addition to the tests called for in 4.4.1, all tanks and connections

shall be tested for tightness after installation and before being placed in service accordance

with 2.4.2.2 and 2.4.2.3, as applicable. Except for underground tanks, this test shall be made at

operating pressure with air, inert gas, or water. Air pressure shall not be used to test tanks that

contain flammable or combustible liquids or vapors.

Single wall underground tanks and piping, before being covered, enclosed, or placed in

use, shall be tested for tightness either hydrostatically or with air pressure at not less than 3 psig

and not more than 5 psig.

Underground secondary containment tanks and horizontal aboveground secondary

containment tanks shall have the primary (inner) tank tested for tightness either hydrostatically

or with air pressure at not less than 3 psig and not more than 5 psig. Additional Testing. Tanks that have been relocated, structurally damaged, repaired, or

are suspected of leaking shall be tested in a manner acceptable to the authority having the

jurisdiction.

MaintenanceMaintenance

Each tank shall be inspected and maintained to ensure compliance with the requirements of this code. Testing requirements for tanks shall be in accordance with Section 4.4

Each tank shall be maintained liquid tight. Each tank that is leaking shall be emptied of liquid or repaired in a manner acceptable to the authority having jurisdiction.

Tanks that have been structurally damaged, have been repaired or reconstructed, or are suspected of leaking shall be tested in accordance with 4.4.1 or in a manner acceptable to the authority having jurisdiction.

Tanks and all tank appurtenances, including normal vents and emergency vents and related devices, shall be properly maintained to ensure that they function as intended.

Openings for gauging on tanks storing Class I liquids shall be provided with a vapor tight cap or cover. Such covers shall be closed when not gauging.

CONCLUSIONCONCLUSION

Underground tank present unique Underground tank present unique challenges not experienced with those challenges not experienced with those

installed aboveground. It is important to installed aboveground. It is important to make sure this is given careful make sure this is given careful

consideration in the installation and consideration in the installation and inspection of underground systems to inspection of underground systems to

minimize problems and provide minimize problems and provide satisfactory servicesatisfactory service.
