Current through Register Vol. 35, No. 6, March 26, 2024
Owners and operators of AST 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 20.5.111 NMAC.
A.
Owners and operators of AST 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 above ground storage tanks
every 30 days for releases.
B.
Owners and operators of AST 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 AST 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 comply
with the requirements of 20.5.111.1105 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 for interstitial monitoring shall not be required to automatically shut
off the submersible turbine pump when a leak 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 ASTs with piping that conveys a regulated substance by suction
shall comply with the requirements in 20.5.111.1107 NMAC, except the 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 a 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)
Petroleum Equipment Institute
RP200, "Recommended Practices for Installation of Aboveground Storage Systems
for Motor Vehicle Fueling";
(3)

Publication RP 1615, "Installation of Underground Hazardous Substances or
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)
