Current through Register Vol. 50, page 114, March 25, 2024

Secondary containment constructed after December 8, 1985, must be constructed according to professional engineering practices, which include the following:

(1) The walls and base must be constructed by means of either:

(a) A synthetic liner at least 30 mils thick beneath 12 inches of compacted clay soil to withstand loading conditions and the discharge of maximum tank capacity considering the full hydrostatic head of the discharged liquid;

(b) Concrete, excluding blocks and bricks, of sufficient thickness and strength to withstand loading conditions and the discharge of maximum tank capacity considering the full hydrostatic head of the discharged liquid;

(c) Steel of sufficient thickness and strength to withstand loading conditions and the discharge of maximum tank capacity considering the full hydrostatic head of discharged liquid; or

(d) Cross-linked polyolefin, defined as crosslinkable high density polyethylene, type 3, Class B, Category 5 resin with minimum 0.5 percent carbon black as defined in American Society for Testing and Materials (ASTM) standard D 1248-84, constructed with a minimum thickness of 3/8 inch, ultraviolet stabilized for outdoor use to give excellent outdoor weatherability, and with a low temperature impact strength of a minimum of 90 foot pounds of impact at 40 degrees Fahrenheit according to the Association of Rotational Molders (ARM) impact test. The cross-linked polyolefin must be constructed of sufficient thickness and strength to withstand loading conditions and the discharge of maximum tank capacity considering the full hydrostatic head of discharged liquid;

(2) All seams and cracks must be sealed;

(3) The capacity of the containment area must be capable of holding 110 percent of the volume of the largest container plus the volume of the butts of all the other tanks inside it; and

(4) Each cross-linked polyolefin containment structure must be permanently marked with an embossment or with a metal certification plate permanently affixed to it. The marking must be in letter and number at least 1/4 inch high located on the side of the containment structure. The marking shall certify that the containment structure complies with all requirements of this section and contain the words "meets specification of ARSD 12:56:13:03" and the date of manufacture including month and year.
