Current through Register Vol. 41, No. 3, September 23, 2024
A. Owners and
operators of UST systems must provide a method, or combination of methods, of
release detection that:
1. Can detect a
release from any portion of the tank and the connected underground piping that
routinely contains product;
2. Is
installed and calibrated in accordance with the manufacturer's instructions,
including routine maintenance and service checks for operability or running
condition;
3. Beginning on January
1, 2021, is operated and maintained, and electronic and mechanical components
are tested for proper operation, in accordance with one of the following:
(i) manufacturer's instructions;
(ii) a code of practice developed by a
nationally recognized association or independent testing laboratory; or
(iii) requirements determined by
the department to be no less protective of human health and the environment
than the two options listed in subdivisions 1 and 2 of this subsection. A test
of the proper operation must be performed at least annually and, at a minimum,
as applicable to the facility, cover the following components and criteria:
a. Automatic tank gauge and other
controllers: test alarm; verify system configuration; test battery
backup;
b. Probes and sensors:
inspect for residual buildup; ensure floats move freely; ensure shaft is not
damaged; ensure cables are free of kinks and breaks; test alarm operability and
communication with controller;
c.
Automatic line leak detector: test operation to meet criteria in subdivision 1
of
9VAC25-580-170
by simulating a leak;
d. Vacuum
pumps and pressure gauges: ensure proper communication with sensors and
controller; and
e. Handheld
electronic sampling equipment associated with groundwater and vapor monitoring:
ensure proper operation.
NOTE: The following code of practice may be used to comply
with subdivision 3 of this subsection. Petroleum Equipment Institute
Publication RP 1200, Recommended Practices for the Testing and Verification of
Spill, Overfill, Leak Detection and Secondary Containment Equipment at UST
Facilities.
4. Meets the performance requirements in
9VAC25-580-160
or
9VAC25-580-170
or Part X (9VAC25-580-380
et seq.) of this chapter as applicable with any performance claims and their
manner of determination described in writing by the equipment manufacturer or
installer. In addition, the methods listed in subdivisions 2, 3, 4, 8, and 9 of
9VAC25-580-160;
subdivisions 1 and 2 of
9VAC25-580-170;
and Part X must be capable of detecting the leak rate or quantity specified for
that method in the corresponding section of the regulation with a probability
of detection of 0.95 and a probability of false alarm of 0.05.
B. When a release detection method
operated in accordance with the performance standards in
9VAC25-580-160,
9VAC25-580-170,
or Part X of this chapter indicates a release may have occurred, owners and
operators must notify the department in accordance with Part V (9VAC25-580-190
et seq.) of this chapter.
C. Any
UST system that cannot apply a method of release detection that complies with
the requirements of this part must complete the closure procedures in Part VII
(9VAC25-580-310
et seq.) of this chapter. For previously deferred UST systems described in
Parts I (9VAC25-580-10 et
seq.) and X of this chapter, this requirement applies on or after the effective
dates described in
9VAC25-580-20 A 1 b
and c and
9VAC25-580-380
A 1.
