Section 20.5.113.1304 - RELEASE DETECTION REQUIREMENTS FOR UST EMERGENCY GENERATOR SYSTEMS INSTALLED OR MODIFIED ON, OR AFTER JULY 24, 2018

Owners and operators of UST emergency generator systems installed on or after the effective date of these regulations shall meet all of the requirements in this section in addition to all of the applicable requirements in 20.5.106 NMAC upon installation.

A. Owners and operators of UST emergency generator systems installed or modified on or after the effective date of these regulations shall use interstitial monitoring in accordance with 20.5.108.810 NMAC to meet the requirements for monthly monitoring.

B. Owners and operators of UST emergency generator systems where the piping is installed or replaced on or after the effective date of these regulations, and the piping conveys a regulated substance under pressure shall use interstitial monitoring and automatic line leak detectors that alert the operator to the presence of a leak by activating an external audible and visual alarm when liquid is detected. Owners and operators of UST emergency generator systems shall meet the requirements of 20.5.108.811 NMAC, except:

(1) Automatic line leak detectors for UST emergency generator systems shall not be required to restrict or shut off the flow of regulated substances; and

(2) Sensors used to meet the interstitial monitoring requirements for UST emergency generator systems shall not be required to automatically shut off the flow of product when liquid is detected in the interstice of the piping or in containment sumps. Sensors used for interstitial monitoring shall activate a secondary audible and visual alarm when liquid is detected.

C. Owners and operators of UST emergency generator systems where the piping is installed or replaced on or after the effective date of these regulations and the piping conveys a regulated substance by suction shall comply with the requirements in 20.5.108.813 NMAC, except that the sensors used for interstitial monitoring shall activate an external audible and visual alarm when liquid is detected either in the interstice of the piping or in containment sumps. Sensors used to meet the interstitial monitoring requirements for UST emergency generator systems shall not be required to automatically shut off the flow of product when liquid is detected in the interstice of the piping or in containment sumps.

D. 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".
