Current through Register Vol. 35, No. 6, March 26, 2024
A. Owners and
operators shall maintain all containment sumps (including but not limited to
turbine sumps, under dispenser sumps, and transition sumps) and draw off liquid
that has accumulated in the containment sumps within one week of the
accumulation, and shall remove any other debris that has accumulated inside the
containment sumps. Owners and operators shall properly treat and dispose of any
accumulated liquid with a visible sheen and the disposal shall be in accordance
with all federal, state, and local statutes, ordinances, and
regulations.
B. Owners and
operators shall maintain all containment sumps associated with interstitial
monitoring of underground piping; the sumps shall be liquid tight and kept free
of water.
C. Owners and operators
of UST systems with single walled containment sumps associated with
interstitial monitoring shall have the integrity of the sump tested no later
than three years after the effective date of these regulations, and every three
years thereafter, in accordance with the following:
(1) Hydrostatic or other test methods shall
be conducted to ensure the containment sumps are liquid tight including at all
penetrations in accordance with one of the following:
(a) the equipment manufacturers developed and
published testing requirements;
(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"; or
(c) 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;
(2)
Hydrostatic test methods using a test apparatus developed specifically for
testing containment sumps shall ensure the containment sumps are liquid tight
including at all penetrations and comply with one of the following:
(a) protocols developed by the manufacturer
of the test apparatus and the certification as listed on
http://www.nwglde.org, the web site
of the national work group on leak detection evaluation; or
(b) protocols developed and published by the
manufacturer of the containment sump; or
(c)
Petroleum Equipment Institute RP
1200, "Recommended Practices for the Testing and Verification of Spill,
Overfill, Leak Detection, and Secondary Containment Equipment at UST
Facilities"; or
(3) A low liquid level hydrostatic test
method may be conducted if all of the following conditions are met:
(a) test method used shall be in accordance
with the following:
(i) the liquid level
meets the third-party certification for the sensor installed in the
sump;
(ii) the duration of the test
shall be a minimum of one hour unless a different test period is specified by
the containment sump manufacturer or in Item (iii) below;
(iii) 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;
(b) either a
hydrostatic test shall be conducted every 12 years in accordance with Paragraph
(1) and (2) of Subsection C or a site check shall be conducted every 12 years
in accordance with in Subsection B of 20.5.118.1801 NMAC.
(c) a sump sensor that automatically shuts
off equipment associated with the sump and meets the requirements for placement
and testing of sensors used for interstitial monitoring in Paragraph 2 of
Subsection B of 20.5.108.811 NMAC;
(4) A low liquid level test per Paragraph (3)
of this subsection shall not be conducted if the following conditions exist:
(a) a liquid is discovered in the sump or
evidence is found that a liquid has been at a level equal to or higher than the
lowest penetration in the sump then testing has to be conducted in accordance
with Paragraph (1) of this subsection;
(b) sensors in containment sumps are
discovered to be located higher than the lowest part of the sump a test shall
be conducted in accordance with Paragraph (1) of this subsection and owners and
operators shall report and investigate a suspected release in accordance with
the requirements in 20.5.118 NMAC; or
(c) a site check conducted in accordance with
Paragraph (3) of this subsection indicates there has been a release from the
containment sump.
D. Owners and operators of UST systems with
double-walled containment sumps associated with interstitial monitoring shall
have the integrity of the sumps tested no later than three years after the
effective date of these regulations, and every three years thereafter, in
accordance with one of the following:
(1)
interstices under vacuum, pressure, or brine filled, are continuously monitored
by use of interstitial sensors or visually inspected every 30 days, and the
monitoring records are maintained in accordance with 20.5.107.714 NMAC. Owners
and operators shall ensure that annual functionality testing or annual
inspections of the monitoring equipment are conducted in accordance with
20.5.108.805 NMAC. Owners and operators who cannot demonstrate that the
interstices of the containment sumps are continuously monitored or inspected
every 30 days shall have the sumps tested in accordance with Subsection C
above; or
(2) containment sumps
with dry interstices that are not continuously monitored are integrity tested
in accordance with Subsection C of this section.
E. All sensors and equipment used to monitor
containment sumps shall be functionality tested annually in accordance with
Subsection B of 20.5.108.805 NMAC.
F. A report shall be produced which includes
the results of the testing, and the report shall be submitted in accordance
with 20.5.107.715 NMAC and maintained in accordance with the requirements in
20.5.107.714 NMAC.
G. Owners and
operators of storage tank systems shall ensure that tests of containment sumps
as required in this section are performed by qualified testers. The
requirements for testers can be found in 20.5.105 NMAC.
H. Owners and operators of storage tank
systems shall dispose of water or other test media used in testing of
components of petroleum storage tank systems, or any accumulated liquid with a
visible sheen, and the disposal shall be in accordance with all federal, state,
and local statutes, ordinances, and regulations. Owners and operators who
temporarily store the test media or water on-site shall do so in accordance
with all federal, state, and local statutes, ordinances, and
regulations.
