20.5.113.1306 ALTERNATE METHODS:
A. If
owners and operators want to install UST emergency generator systems to meet
requirements in this part or want to install release detection equipment for
tanks or piping installed prior to the effective date of these regulations with
materials or methods that are not in accordance with the current edition of an
industry standard or code of practice developed by a nationally recognized
association or independent testing laboratory, owners and operators shall apply
in writing to the department, shall provide supporting documentation, and shall
not begin the installation unless and until the department approves the request
in writing. At a minimum, the request
for an alternate method shall contain the following:
(1) date the form is completed;
(2) facility name, facility ID
number, address (with county) and telephone number;
(3) owner name, owner ID number,
address and telephone number;
(4) citation to regulation for which
alternate method or material (such as type of piping) is requested;
(5) brief description of the proposed
alternate method or material;
(6) justification of proposed
alternate method or material, including citation to a standard or code
supporting its use, if available; and
(7) demonstration of its equivalent
protection of public health, safety and welfare and the environment.
B. Another
type of release detection method, or combination of methods, may be used if
approved pursuant to this section for tanks or piping installed prior to the
effective date of the regulations, and if, for USTs, the method can detect a
two-tenth gallon per hour leak rate monthly or a release of 150 gallons within
a month from a tank with a probability of detection of 0.95 and a probability
of false alarm of 0.05.
C. The
department may approve another release detection method for tanks or piping
installed prior to the effective date of the regulations if owners and
operators can demonstrate that the method can detect a release as effectively
as any of the applicable methods allowed in 20.5.108 NMAC. In comparing methods, the department shall
consider the size of release that the method can detect and the frequency and
reliability with which it can be detected.
If the method is approved, the owner and operator shall comply with any
conditions imposed by the department on its use to ensure the protection of
public health, safety and welfare and the environment. The department shall not grant the request
unless owners and operators demonstrate that the request will provide
protection of public health, safety and welfare and the environment equivalent
to the protection provided by the methods in this part.
