20.5.112.1208 ALTERNATE METHODS:
A. If
owners and operators want to install AST emergency generator systems to meet
the 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 and 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 and piping installed prior to the
effective date of these regulations, and if, for ASTs, it can detect a 0.2
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 and piping
installed prior to the effective date of these regulations if owners and
operators can demonstrate that the method can detect a release as effectively
as any of the applicable methods allowed in 20.5.111 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.
