A. Owners and operators of above ground storage tank systems where piping conveys regulated substances under suction and was installed prior to the effective date of these regulations shall use one of the following methods. These methods shall be designed to detect a release from any portion of underground piping:

(1) An annual line tightness test shall be conducted and the tightness testing shall be capable of detecting a one-tenth gallon per hour leak at one and one-half times the operating pressure; or

(2) Interstitial monitoring shall be used in accordance with all of the requirements in 20.5.11.1103 NMAC and 20.5.11.1105 NMAC;

B. Release detection is not required for suction piping that is designed and constructed to meet all of the following standards:

(1) the below-grade piping operates at less than atmospheric pressure;

(2) the below-grade piping is sloped so that the contents of the pipe will drain back into the storage tank if the suction is released;

(3) only one check valve is included in each suction line;

(4) the check valve is located directly below and as close as practical to the suction pump; and

(5) compliance with Paragraphs (2) through (4) of Subsection B of this section is demonstrated.

C. Owners and operators shall use one or more of the following to comply with the requirements of this section:

(1)Petroleum Equipment Institute Publication RP100, "Recommended Practices for Installation of Underground Liquid Storage Systems";

(2)Petroleum Equipment Institute RP200, "Recommended Practices for Installation of Aboveground Storage Systems for Motor Vehicle Fueling";

(3)American Petroleum Institute Publication RP 1615, "Installation of Underground Hazardous Substances or Petroleum Storage Systems";

(4)American Petroleum Institute 570, "Piping Inspection Code: In-Service Inspection, Repair, and Alteration of PipingSystems"; and

(5)American Society of Mechanical Engineering Standard B31.3, "Process Piping".

D. Owners and operators shall maintain all records of release detection and testing in accordance with 20.5.111.1111 NMAC and provide to the department reports for all release detector testing, line tightness testing, and sensor testing in accordance with 20.5.111.1112 NMAC.
