Leak Detection System Functionality Testing.
3 RCNY § 2306-02
in effect§ 2306-02 Leak Detection System Functionality Testing.
(a) Scope. This section sets forth standards, requirements and procedures for the periodic testing of underground liquid motor fuel storage and dispensing systems leak detection systems pursuant to FC 2306.9.3.
(b) General Provisions.
(1) Frequency. Pursuant to FC 2306.9.3, a functionality test of the leak detection system shall be conducted, at the owner's risk, before a representative of the Department at least once every two (2) years.
(2) Supervision. The leak detection system functionality test shall be conducted by a holder of a certificate of license for liquid motor fuel storage and dispensing systems, or a person employed and supervised by such certificate of license holder. The individual conducting the test shall remain on the premises while such test is being conducted and until the system has been returned to normal operation in accordance with 3 RCNY § 2306-02(c)(5). The Department may require individuals performing such leak detection test to be trained and/or certified by the manufacturer to conduct such test. Upon request, proof satisfactory to the Department shall be submitted attesting to the individual's training/certification for such leak detection system.
(3) Scheduling. A leak detection system functionality test shall be scheduled with the Bulk Fuel Unit of the Bureau of Fire Prevention.
(4) Fire extinguishing system operational. No leak detection system functionality test shall be conducted if the fire extinguishing system required to protect the dispensers is out-of-service or not in good working order.
(5) Smoking and ignition sources. All sources of ignition in the test area shall be eliminated from the area in which a leak detection system functionality test is to be conducted. Signs reading "NO SMOKING – NO OPEN FLAMES" shall be conspicuously posted in such area.
(6) Testing area security. The areas surrounding the dispensers, tanks or other equipment or systems tested shall be cordoned off by portable barricades or signs, rope or tape to prevent unauthorized persons or motor vehicles from entering the area.
(7) Electrical equipment. All electrical equipment used for testing shall be of a type listed as intrinsically safe or suitable for use in hazardous locations. Interlocks shall be provided to ensure that grounding is made prior to electrical contact. Power to electrical equipment shall not be turned on until all electrical connections are made. Connection to power source shall be the final connection made.
(c) Leak Detection System Testing Requirements. Functionality tests of leak detection systems shall be conducted in accordance with the manufacturer's instructions and the following standards and procedures:
(1) Testing of probes. Except as provided in 3 RCNY § 2306-02(c)(2), leak detection probes shall be removed from their installed location, and manually tested by exposing such probes to liquid motor fuel. Probes capable of discriminating liquid motor fuel from water shall also be exposed to water. Leak detection probes which cannot be removed from their installed location may be tested by a method recommended by the manufacturer and acceptable to the Department.
(2) Testing of discharge line leak detectors. Discharge line leak detectors shall be tested by withdrawing liquid motor fuel from the impact valve port. Liquid motor fuel shall be withdrawn at a rate equal to the minimum rate that the line leak detector is required to activate.
(3) Dispensing of fuel for testing purposes. The liquid motor fuel to be used for testing purposes shall be dispensed from the liquid motor fuel storage system into a metal safety can of a capacity not exceeding 2 1/2 gallons. Except as provided in 3 RCNY § 2306-02(c)(2), such liquid motor fuel shall be withdrawn through the storage system dispenser. Liquid motor fuel withdrawn from the storage system shall be returned to the storage system through the fill connection.
(4) Standard for successful test. A leak detection system test shall be deemed successful if:
(A) each tank-interstitial leak detection probe in the system, when exposed to liquid motor fuel and, if designed for such purpose, water, causes the activation of the audible and visible alarm.
(B) each pump sump leak detection probe in the system, when exposed to liquid motor fuel and, if designed for such purpose, water, causes:
(1) the activation of the audible and visible alarm, and
(2) the shutdown of the liquid motor fuel pump.
(C) each dispenser pan leak detection probe in the system, when exposed to liquid motor fuel and, if designed for such purpose, water, causes:
(1) the activation of the audible and visible alarm, and
(2) the shutdown of the affected dispenser or liquid motor fuel pump.
(D) each electronic line leak detector in the system, upon detection of liquid motor fuel leak, causes:
(1) the activation of the audible and visible alarm, and
(2) the shutdown of the liquid motor fuel pump or a significant restriction of liquid motor fuel flow.
(E) each mechanical line leak detector in the system, upon detection of a liquid motor fuel leak, causes the shutdown of the liquid motor fuel pump or the stopping of liquid motor fuel flow at any rate exceeding three (3) gallons per hour.
(5) Restoration of system. Upon successful completion of a leak detection system functionality test, liquid motor fuel storage and dispensing system, including the leak detection system, shall be returned to normal operation and checked to ensure that it is in good working order.
(d) Portable Fire Extinguisher Requirements. A portable fire extinguisher having at least a 40-B:C rating shall be readily available for use.
