Current through Register Vol. 35, No. 23, December 10, 2024

Section 20.5.112.1206 - RELEASE DETECTION REQUIREMENTS FOR ABOVE GROUND STORAGE TANK EMERGENCY GENERATOR SYSTEMS INSTALLED OR MODIFIED ON, OR AFTER, JULY 24, 2018

Owners and operators of AST 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 20.5.111 NMAC upon installation.

A. Owners and operators of AST emergency generator systems installed or modified on or after the effective date of these regulations must implement a method, or combination of methods, that monitors above ground storage tanks every 30 days for releases using an applicable method in 20.5.111 NMAC.

B. Owners and operators of AST 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 AST emergency generator systems shall comply with the requirements of 20.5.111.1106 NMAC, except:

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

(2) sensors used to meet the interstitial monitoring requirements for AST 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 or visual alarm when liquid is detected.

C. Owners and operators of ASTs 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 20.5.111.1108 NMAC, except the sensors used for interstitial monitoring shall activate an external audible and visual alarm when a leak is detected either in the interstice of the piping or in containment sumps. Sensors used to meet the interstitial monitoring requirements for AST 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)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 Petroleum Storage Systems";

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

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

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

(7)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".
