discontinuing periodic monitoring of the equipment.
(4) Single walled containment sumps installed
to meet spill prevention requirements shall be tested every three years.
Testing shall be by a vacuum, pressure, or liquid method that meets one of the
following:
(a) the equipment manufacturer's
developed and published testing requirements; or
(b)
Petroleum Equipment Institute RP
1200, "Recommended Practices for the Testing and Verification of Spill,
Overfill, Leak Detection, and Secondary Containment Equipment at UST
Facilities".
(5)
Double walled containment sumps that are installed to meet spill prevention
requirements shall either be tested every three years or monitored as follows:
(a) Testing shall be by a vacuum, pressure,
or liquid method that meets one of the following:
(i) the equipment manufacturers developed and
published testing requirements; or
(ii)
Petroleum Equipment Institute RP
1200, "Recommended Practices for the Testing and Verification of Spill,
Overfill, Leak Detection, and Secondary Containment Equipment at UST
Facilities";
(b)
Monitoring shall be performed either continuously or monthly with a sensor or
visual inspection as follows:
(i) continuous
monitoring by liquid, pressure, or vacuum shall be done electronically and
shall activate an alarm when liquid is detected in the interstice of the
sump;
(ii) monthly monitoring with
a sensor shall be conducted at least every 30 days and in accordance with
either the manufacturer's instructions or the current edition of a national
code or standard;
(iii) monthly
monitoring by visual inspection may be used if a leak from the inner wall of
the sump can be detected by a visual check of the
interstice;
(6) Containment sumps installed prior to the
effective date of these regulations shall be tested in accordance with
Paragraph (2) of Subsection C of this section prior to the beginning of monthly
monitoring, if applicable;
(7)
Sensors used for monthly monitoring of spill prevention equipment or
containment sumps associated with spill prevention equipment shall be
functionality tested annually in accordance with the requirements in Subsection
B of 20.5.108.808 NMAC;
(8) If
evidence is found during the monthly monitoring that containment sumps or spill
prevention equipment are no longer liquid tight, owners and operators shall
have the equipment repaired or replaced in accordance with the requirements in
20.5.107.709 NMAC;
(9) A report
shall be produced which includes the results of any vacuum, pressure, or liquid

(2) Prior to the inspection of flow
restrictors on vent lines on existing USTs, either a vacuum or pressure decay

to placing the tank back into service.
(3) Flow restrictors on vent lines that are
found to be inoperable during the inspection shall be replaced with different
type of overfill prevention equipment. Flow restrictors shall not be installed
or replaced with another flow restrictor on or after the effective date of
these regulations.
(4) Drop tube
style overfill prevention equipment shall be removed from the tank and
inspected for operability.
(5) If
more than one type of overfill prevention equipment is installed on a UST,
owners and operators shall ensure that none of them will interfere with the
proper operation of any of the others.
(6) A report on tests and inspections of
