Section 20.5.113.1303 - RELEASE DETECTION REQUIREMENTS FOR UST EMERGENCY GENERATOR SYSTEMS INSTALLED PRIOR TO JULY 24, 2018

Owners and operators of UST emergency generator systems installed prior to the effective date of these regulations shall meet all of the requirements in this section in addition to all of the applicable requirements in 20.5.108 NMAC.

A. Owners and operators of UST emergency generator systems shall implement a method, or combination of methods, no later than three years after the effective date of these regulations that monitors underground storage tanks every 30 days for releases.

B. Owners and operators of UST emergency generator systems shall provide a method, or combination of methods, of release detection for underground piping no later than three years after the effective date of these regulations. The method, or combination of methods, shall follow the current edition of an industry standard or code of practice developed by a nationally recognized association or independent testing laboratory approved in advance by the department. Owners and operators shall comply with the requirements for release detection for underground piping as follows:

(1) Owners and operators of UST emergency generator systems with piping that conveys a regulated substance under pressure shall use automatic line leak detectors for emergency generators that alert the operator to the presence of a leak by activating a visual and audible alarm when a leak is detected and that meet the requirements of 20.5.108.810 NMAC, except:

(a) Automatic line leak detectors for emergency generators shall not be required to restrict or shut off the flow of regulated substances.

(b) Sensors used to meet the interstitial monitoring requirements shall not be required to automatically shut off the submersible turbine pump when a liquid is detected in the interstice of the piping or in containment sumps. Sensors used for interstitial monitoring shall activate an external audible and visual alarm when liquid is detected.

(2) Owners and operators of UST emergency generator systems with piping that conveys a regulated substance by suction shall comply with the requirements in 20.5.108.812 NMAC, except sensors used for interstitial monitoring shall not be required to restrict or shut off the flow of regulated substances. Sensors used for interstitial monitoring shall activate an audible and visual external alarm when liquid is detected.

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

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

(4)American Society of Mechanical Engineers Standard B31.3, "Process Piping";

(5)National Fire Protection Association Standard 110, "Standard for Emergency and Standby Power Systems"; and

(6)Petroleum Equipment Institute publication RP1400, "Recommended Practices for the Design and Installation of Fueling Systems for Emergency Generators, Stationary Diesel Engines, and Oil Burner Systems".
