for specific requirements for floating pans.
2.13.4.3 Truck and Rail Loading Facilities. Tank truck and
tank car loading facilities constructed or modified after
December 17, 1980 which load an annual average of more than
20,000 gallons (76 000 L) per day of fuel having a true vapor
pressure (TVP) of 0.75 psia (5 kPa) or greater must discharge
the vapors resulting from such operations into a closed
system. Ensure this system leads to a vapor recovery or
disposal system which is capable of removing 95 percent of the
petroleum vapor before final discharge into the atmosphere.
Equip bulk gasoline terminals (handling fuels with TVP $
4.003 psia or 27.60 kPa) with a vapor collection system
designed to collect total organic compound (TOC) vapors
displaced from tank trucks during loading. Emissions from the
vapor control system due to loading must not exceed 35 mg of
TOC per liter of gasoline loaded. For facilities with an
existing vapor processing system, the TOC emissions must not
exceed 80 mg of TOC per liter of gasoline loaded (40 CFR 60
Subpart XX).
2.13.4.4 Permit Requirements. Air quality permits are
typically required for the construction of petroleum storage
and dispensing facilities. It is essential for designers to
review regulatory requirements to ensure incorporation of
proper environmental controls. State and local regulations
are primary sources for air quality requirements, but for
particularly large facilities, it is also beneficial to confer
with the EPA regional office. The permit review and air
quality controls will further depend on whether the
construction site is located in an attainment or non-
attainment area for ozone. Different permit programs apply in
these areas, but they can both yield strict control
requirements depending on the air quality of the area. An
emissions offset analysis may be necessary before any
construction permit can be granted. This analysis will
require and demonstrate a reduction in VOC emissions from
other sources in the locality where the new source
construction is to take place. The offset can be obtained by
providing new or better controls or otherwise decreasing
emissions from an existing source.
