R 336.1609 Loading delivery vessels with organic compounds having true vapor pressure of more than 1.5 psia at existing loading facilities handling 5,000,000 or more gallons of the compounds per year.

Rule 609. (1) After June 30, 1981, it is unlawful for a person to load, or allow the loading of, any organic compound that has a true vapor pressure of more than 1.5 psia at actual conditions from any stationary vessel into any delivery vessel located at the following existing loading facilities that are outside any county listed in table 61-a and have a throughput of 5,000,000 or more gallons of the compounds per year, unless the delivery vessel is filled by a submerged fill pipe: (a) An existing facility installed outside the counties listed in table 61-a before July 1, 1979. (b) An existing facility installed or modified in this state after July 1, 1979, and before March 1, 2023. (2) It is unlawful for a person to load, or allow the loading of, any organic compound that has a true vapor pressure of more than 1.5 psia at actual conditions from any stationary vessel into any delivery vessel located at the following existing loading facilities which have a throughput of 5,000,000 or more gallons of the compounds per year, unless the delivery vessel is controlled by a vapor recovery system as described in subrule (3) of this rule: (a) An existing facility installed in counties listed in table 61-a before July 1, 1979. (b) An existing facility installed or modified in this state after July 1, 1979, and before March 1, 2023. (3) Proper operation of the vapor recovery system as required by subrule (2) of this rule is when all displaced organic vapor and air are captured by means of a vapor tight collection line and the system recovers the organic vapor such that emissions to the atmosphere do not exceed 0.7 pounds of organic vapor per 1,000 gallons of organic compounds loaded. (4) Any delivery vessel located at a facility that is subject to the provisions of subrule (2) of this rule must be equipped, maintained, or controlled with all of the following: (a) An interlocking system or procedure to ensure that the vapor tight collection line is connected before any organic compound can be loaded. (b) A device to ensure that the vapor tight collection line closes upon disconnection to prevent the release of organic vapor. (c) A device to accomplish complete drainage before the loading device is disconnected, or a device to prevent liquid drainage from the loading device when not in use. (d) Pressure-vacuum relief valves that are vapor tight and set to prevent the emission of displaced organic vapor during the loading of the delivery vessel, except under emergency conditions. (e) Hatch openings that are kept closed and vapor tight during the loading of the delivery vessel. (5) A person who is responsible for the operation of all control measures required by this rule shall develop written procedures for the operation of all such control measures. The procedures must be posted in an accessible, conspicuous location near the loading device. (6) The provisions of this rule do not apply to the loading of the following: (a) Crude oil or condensate into delivery vessels at production facilities if loading is accomplished with a submerged fill pipe. (b) Butane, isobutane, propane, propylene, butylene, C3-C4 mixtures, and mixtures of these organic compounds that comply with the following specified requirements: (i) Utilizes a pressurized loading system that does not allow organic vapor to be discharged from the delivery vessel during loading. (ii) Utilizes a device to ensure the loading line closes upon disconnection to prevent release of organic vapor. (iii) Ensures that all pressure-vacuum relief valves are vapor-tight and set to prevent the emission of organic vapor during the loading of the delivery vessel, except under emergency conditions. (iv) All hatch openings are kept closed and vapor-tight during the loading of the delivery vessel. (v) Written procedures for the operation of the loading device are posted in an accessible, conspicuous location near the loading device.
