This February 6, 1998 Federal Register notice (63 FR 6288-6336) notice contains the proposed rule and preamble for 40 CFR Part 63, National Emission Standards for Hazardous Air Pollutants: Oil and Natural Gas Production and Natural Gas Transmission and Storage.
Action: Proposed rules and notice of public hearing.
SUMMARY: These proposed national emission standards for hazardous air
pollutants (NESHAP) would limit emissions of hazardous air pollutants
(HAP) from oil and natural gas production and natural gas transmission
and storage facilities. These proposed rules would implement section
112 of the Clean Air Act (Act) and are based on the Administrator's
determination that oil and natural gas production and natural gas
transmission and storage facilities emit HAP identified on the EPA's
list of 188 HAP.
The EPA estimates that approximately 65,000 megagrams per year (Mg/
yr) of HAP are emitted from major and area sources in these source
categories. The primary HAP emitted by the facilities covered by these
proposed standards include benzene, toluene, ethyl benzene, mixed
xylenes (collectively referred to as BTEX), and n-hexane. Benzene is
carcinogenic and all can cause toxic effects following exposure. The
EPA estimates that these proposed NESHAPs would reduce HAP emissions in
the oil and natural gas production source category by 57 percent and in
the natural gas transmission storage source category by 36 percent.
Also, the EPA is amending the list of source categories established
under section 112(c) of the Act. Natural gas transmission and storage
is being listed as a category of major sources and oil and natural gas
production is being listed as a category of area sources in addition to
its major source listing.
