ARSD 74:56:01:06. Performance standards for new UST systems -- Piping

The underground piping for a new UST system must be designed, constructed, and protected from corrosion in accordance with a code of practice developed by a nationally recognized association or independent testing laboratory as specified in 40 C.F.R. § 280.20, as revised on July 15, 2015, for each type of piping listed. Underground piping that may be used in a new UST system is as follows: (1) Piping constructed of non-corrodible material; (2) Piping that is coated steel and cathodically protected with a field-installed cathodic protection system that is designed by a corrosion expert and operated and maintained in accordance with § 74:56:01:14; or (3) Piping whose design, construction, and corrosion protection is determined by the department to prevent the release of any stored regulated substance in a manner that is no less protective of human health and the environment than the requirements in subdivisions (1) and (2) of this section. Any new piping installed after January 1, 2009, within 1,000 feet of an existing community water system or any potable drinking water well must have secondary containment and be monitored for leaks in accordance with § 74:56:01:30. Any new piping installed after October 13, 2018, must have secondary containment, including under dispenser sumps in accordance with § 74:56:01:10.03 and be monitored for leaks in accordance with § 74:56:01:30.
