105P       (1)  At volatile organic compound (VOC) loading operations other than gasoline terminals, gasoline bulk plants, and marine terminals, no person shall permit the loading of VOC with a true vapor pressure greater than or equal to 0.5 psia under actual storage conditions to transport vessels unless the vapors are processed by a vapor recovery system or are controlled by a vapor balance system, as defined in §115.10 of this title (relating to Definitions).  The vapor recovery system shall maintain a control efficiency of at least 90%.

105P       (2)  No person shall permit the unloading of VOC with a true vapor pressure greater than or equal to 0.5 psia under actual storage conditions from any transport vessel unless the transport vessel is kept vapor-tight at all times until the vapors remaining in the transport vessel after unloading are discharged to a vapor recovery system if the transport vessel is refilled, degassed, and/or cleaned in one of the counties in the Beaumont/Port Arthur, Dallas/Fort Worth, El Paso, and Houston/Galveston areas.  The requirement to discharge the vapors remaining in the transport vessel after unloading to a vapor recovery system does not apply if the transport vessel is refilled, degassed, and/or cleaned at an operation for which control of the vapors is not required.

105P            (A)  All liquid and vapor lines are:

105P                 (i)  equipped with fittings which make vapor-tight connections that close automatically when disconnected; or

105P                 (ii)  equipped to permit residual VOC in the loading line after loading is complete to discharge into a recovery or disposal system which routes all VOC emissions to a vapor recovery system or a vapor balance system.

105P            (B)  There are no VOC leaks, as defined in §115.10 of this title, when measured with a hydrocarbon gas analyzer, and no liquid or vapor leaks, as detected by sight, sound, or smell, from any potential leak source in the transport vessel and transfer system (including, but not limited to, liquid lines, vapor lines, hatch covers, pumps, and valves, including pressure relief valves).

105P                 (ii)  not occur while VOC is being transferred.

105P            (D)  Any openings in a transport vessel during unloading are limited to minimum openings which are sufficient to prevent collapse of the transport vessel.

105P       (7)  No person shall permit the transfer of gasoline from a gasoline bulk plant into a transport vessel, unless the following requirements are met:

105P            (A)  all unloading of marine vessels; and

105P            (B)  all loading of marine vessels in ozone nonattainment areas other than the Houston/Galveston area.

105P       (5)  Gasoline bulk plants which load less than 4,000 gallons (15,142 liters) of gasoline into transport vessels per day averaged over any consecutive 30-day period are exempt from the provisions of §115.211(a)(2), §115.212(a)(7), and §115.216(a)(4) of this title (relating to Emission Specifications; Control Requirements; and Monitoring and Recordkeeping Requirements).

105P       (6)  VOC loading operations other than gasoline terminals, gasoline bulk plants, and marine terminals are exempt from the control requirements of §115.212(a)(1) of this title if the overall control of emissions at the account from the loading of VOC (excluding VOC loading into marine vessels and VOC loading at gasoline terminals and gasoline bulk plants) with a true vapor pressure between 0.5 and 11 psia under actual storage conditions is at least 90%, and the following requirements are met.

105P            (A)  To qualify for the exemption available under this paragraph after December 31, 1996, the owner or operator of a VOC loading operation for which a control plan was not previously submitted shall submit a control plan to the executive director, the appropriate regional office, and any local air pollution control program with jurisdiction which demonstrates that the overall control of emissions at the account from the loading of VOC with a true vapor pressure between 0.5 and 11 psia under actual storage conditions will be at least 90%.  Any control plan submitted after December 31, 1996, must be approved by the executive director before the owner or operator may use the exemption available under this paragraph for compliance.  For each loading rack and any associated control device at the account, the control plan shall include the EPN, the FIN, the throughput of VOC with a true vapor pressure between 0.5 and 11 psia under actual storage conditions for the preceding calendar year, a plot plan showing the location, EPN, and FIN of each loading rack and any associated control device, the controlled and uncontrolled emission rates for the preceding calendar year, and an explanation of the recordkeeping procedure and calculations which will be used to demonstrate compliance.

105P            (B)  In order to maintain exemption status under this paragraph, the owner or operator of the VOC loading operation shall submit an annual report no later than March 31 of each year to the executive director, the appropriate regional office, and any local air pollution control program with jurisdiction which demonstrates that the overall control of emissions at the account from the loading of VOC with a true vapor pressure between 0.5 and 11 psia under actual storage conditions during the preceding calendar year is at least 90%.  For each loading rack and any associated control device at the account, the report shall include the EPN, the FIN, the throughput of VOC with a true vapor pressure between 0.5 and 11 psia under actual storage conditions for the preceding calendar year, a plot plan showing the location, EPN, and FIN of each loading rack and any associated control device, and the controlled and uncontrolled emission rates for the preceding calendar year.

105P            (C)  marine loading operations which use a vapor balance system to control emissions from the marine vessel to fixed roof storage tank(s).  For the purposes of this paragraph, vapor balance system is defined as a closed system that transfers vapor displaced from the tank of a vessel receiving cargo into a tank of the vessel or facility delivering cargo via an arrangement of piping and hoses used to collect vapor emitted from a vessel's cargo tanks;

105P            (D)  non-dedicated loading lines when commodities with a true vapor pressure less than 0.5 psia are transferred, provided that after transfer of VOC with a true vapor pressure greater than or equal to 0.5 psia these non-dedicated loading lines are cleaned, purged, and the residual vapors controlled of VOC with a true vapor pressure greater than or equal to 0.5 psia; and
