S.D. Admin. R. 12:44:05:08
Secondary containment constructed in accordance with § 12:44:05:07, after July 1, 1989, must have a leak detection system located beneath the synthetic liner and the 6-inch compacted clay soil layer, beneath the concrete base (floor) when concrete construction is utilized, and within the soil beneath the cross-linked polyolefin secondary containment structures unless the cross-linked polyolefin secondary containment structure is sitting on a poured concrete base. A series of perforated gravity collection pipe, sufficient in number and size and connected to a monitoring pipe or pipes outside of the secondary containment, must be employed in the construction of the secondary containment to detect possible leaks of the secondary containment system. Other methods of leak detection may be utilized to monitor the secondary containment system, if approved by the secretary.
