Current through Reg. 49, No. 28; July 12, 2024
A vapor balance system will be assumed to comply with the
						specified emission limitation of §
											115.221
						of this title (relating to Emission Specifications) if the following conditions
						are met:
(1) the container is equipped
					 with a submerged fill pipe as defined in §
											101.1 of
					 this title (relating to Definitions). The path through the submerged fill pipe
					 to the bottom of the tank must not be obstructed by a screen, grate, or similar
					 device whose presence would preclude the determination of the submerged fill
					 pipe's proximity to the tank bottom while the submerged fill tube is properly
					 installed;
(2) a vapor-tight return
					 line is connected before gasoline can be transferred into the storage
					 container;
(3) no avoidable
					 gasoline leaks, as detected by sight, sound, or smell, exist anywhere in the
					 liquid transfer or vapor balance systems;
(4) the vapor return line's cross-sectional
					 area is at least one-half of the product drop line's cross-sectional
					 area;
(5) in the Beaumont-Port
					 Arthur, Dallas-Fort Worth, El Paso, and Houston-Galveston-Brazoria areas and in
					 the covered attainment counties, as defined in §
											115.10 of
					 this title (relating to Definitions), the only atmospheric emission during
					 gasoline transfer into the storage container is through a storage container
					 vent line equipped with a pressure-vacuum relief valve set to open at a
					 pressure of no more than eight ounces per square inch (3.4 kilopascals
					 (kPa));
(6) after unloading, the
					 tank-truck tank is kept vapor-tight until the vapors in the tank-truck tank are
					 returned to a loading, cleaning, or degassing operation and discharged in
					 accordance with the control requirements of that operation;
(7) the gauge pressure in the tank-truck tank
					 does not exceed 18 inches of water (4.5 kPa) or vacuum exceed six inches of
					 water (1.5 kPa);
(8) no leak, as
					 defined in §
											101.1 of
					 this title, exists from potential leak sources when measured with a hydrocarbon
					 gas analyzer;
(9) in the
					 Beaumont-Port Arthur, Dallas-Fort Worth, El Paso, and
					 Houston-Galveston-Brazoria areas, any storage tank installed after November 15,
					 1993, which is required to install Stage I control equipment must be equipped
					 with a dual-point vapor balance system, as defined in §
											115.10 of
					 this title. In addition, any modification to a storage tank existing prior to
					 November 15, 1993, requiring excavation of the top of the storage tank must be
					 equipped with a dual-point vapor balance system, even if the original
					 installation utilized coaxial Stage I connections;
(10) in the covered attainment counties, any
					 storage tank installed after December 22, 1998 which is required to install
					 Stage I control equipment must be equipped with a dual-point vapor balance
					 system, as defined in §
											115.10 of
					 this title. In addition, any modification to a storage tank existing prior to
					 December 22, 1998, requiring excavation of the top of the storage tank must be
					 equipped with a dual-point vapor balance system, even if the original
					 installation utilized coaxial Stage I connections; and
(11) any gasoline dispensing facility that no
					 longer meets an exemption in §
											115.227 of
					 this title (relating to Exemptions) because of an increase in throughput shall
					 have 120 days to come into compliance with the provisions of this section and
					 will remain subject to the provisions of this section, even if its gasoline
					 throughput later falls below exemption limits. However, if gasoline throughput
					 exceeds the exemption limit due to a natural disaster or emergency condition
					 for a period not to exceed one month, upon written request, the executive
					 director may grant a facility continued exempt status.
