Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
				  General. Equipment utilized in gasoline vapor recovery shall be tested
				  according to the requirements set forth in the following applicable standards.
(1) Flame Arrestors. Flame Arrestors to be
				  installed in either fuel, vapor, or vent lines shall be tested in accordance
				  with the requirements of U.L. Standard 525, available from Underwriters
				  Laboratories, Inc., 333 Pfingsten Road, Northbrook, IL 60062, and as approved
				  by the State Fire Marshal.
(2) Hose
				  Nozzle Valves. Hose nozzle valves used in conjunction with gasoline vapor
				  recovery systems shall be tested in accordance with the requirements of U.L.
				  Standard 842, available from Underwriters Laboratories, Inc., 333 Pfingsten
				  Road, Northbrook, IL 60062, and as approved by the State Fire
				  Marshal.
(3) Carbon/Charcoal
				  Canisters. Carbon/charcoal canisters utilized in gasoline vapor recovery
				  systems shall withstand, without failure, a test pressure of plus or minus 150%
				  of the maximum operating pressure. The canister material shall also be able to
				  withstand temperatures created by the materials contained therein.
(4) Pressure Regulators. Gasoline vapor
				  pressure regulators utilized in a vapor recovery system shall be approved for
				  the intended use.
(5) Ignition
				  Controls. Ignition controls including, but not limited to, such devices as
				  flame detectors, flame sensors, ignition transformers, electrical control
				  units, alarms, flame indicators, utilized as a component of a gasoline vapor
				  recovery system shall be approved by the State Fire Marshal for its intended
				  use.
(6) Refrigeration Units.
				  Refrigeration units utilized in processing vapors in gasoline vapor recovery
				  systems shall be approved for their intended use.
(7) Pressure/Vacuum Valves. Pressure/vacuum
				  valves utilized in gasoline vapor recovery systems shall be approved by the
				  State Fire Marshal for their intended use.
(8) Internal Explosion/Ignition Test. The
				  processing unit shall be subjected to a series of internal explosion/ignition
				  tests, during performance/operation safety testing, such that ignition of an
				  explosion air/gasoline vapor mixture occurs within the confines of the
				  processing unit piping. The explosion shall not propagate beyond the inlet
				  Flame Arrestor(s). The processing unit and Flame Arrestors shall provide a
				  degree of isolation between other installation components and the processing
				  unit, and between the processing unit and the remainder of the installation,
				  and between the processing unit and the storage tank. The operating function of
				  the unit, shall not be impaired as a result of such tests. Adequate sensors
				  shall be utilized to insure that:
(1) an
				  explosive gasoline/air vapor mixture was present;
(2) that an ignition of the vapor mixture did
				  occur; and
(3) that the safeguards
				  installed in the processing unit did function.
(9) Other Equipment. Such other equipment
				  which may be utilized in gasoline vapor control systems shall also be tested to
				  applicable standards as may be determined necessary by the State Fire
				  Marshal.
