Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) This source category consists of the
						following industry segments:
(1)
Offshore petroleum and natural gas production.
Offshore
						petroleum and natural gas production is any platform structure, affixed
						temporarily or permanently to offshore submerged lands, that houses equipment
						to extract hydrocarbons from the ocean or lake floor and that processes and/or
						transfers such hydrocarbons to storage, transport vessels, or onshore. In
						addition, offshore production includes secondary platform structures connected
						to the platform structure via walkways, storage tanks associated with the
						platform structure and floating production and storage offloading equipment
						(FPSO). This source category does not include emissions from offshore drilling
						and exploration that is not conducted on production platforms.
(2)
Onshore petroleum and natural gas
						production.
Onshore petroleum and natural gas production means all
						equipment on a well-pad or associated with a well pad (including compressors,
						generators, dehydrators, storage vessels, and portable non-self-propelled
						equipment which includes well drilling and completion equipment, workover
						equipment, gravity separation equipment, auxiliary non-transportation-related
						equipment, and leased, rented or contracted equipment) used in the production,
						extraction, recovery, lifting, stabilization, separation or treating of
						petroleum and/or natural gas (including condensate). Onshore natural gas
						processing equipment as defined in section
						95150(a)(3) that
						is owned and/or operated by the facility owner/operator and located within the
						same basin is considered "associated with a well pad" and is included with the
						onshore petroleum and natural gas production facility, unless such equipment is
						required to be reported as part of a separate onshore petroleum and natural gas
						processing facility. Gas processing plants that have an annual average
						throughput of 25 MMscf per day or greater are not included in this segment.
This equipment also includes associated storage or
						  measurement vessels and all enhanced oil recovery (EOR) operations (both
						  thermal and nonthermal), and all petroleum and natural gas production equipment
						  located on islands, artificial islands, or structures connected by a causeway
						  to land, an island, or an artificial island. Crude oil and associated gas that
						  is piped to an onshore production facility as an emulsion as defined in section
						  95102(a) must
						  follow the requirements of section
						  95156(a)(7)-(10)
						  and meet the metering requirements of section
						  95103(k) by
						  measuring the emulsion before the first separation tank at the onshore
						  production facility and not at the platform.
(3)
Onshore natural gas
						processing.
Natural gas processing means the separation of natural gas
						liquids (NGLs) or non-methane gases from produced natural gas, or the
						separation of NGLs into one or more component mixtures. Separation includes one
						or more of the following: forced extraction of natural gas liquids, sulfur and
						carbon dioxide removal, fractionation of NGLs, or the capture of
						CO2 separated from natural gas streams. This segment
						also includes all residue gas compression equipment owned or operated by the
						natural gas processing plant. This industry segment includes processing plants
						that have an annual average throughput of 25 MMscf per day or greater. This
						industry segment also includes fractionation facilities that have no petroleum
						and gas production activity within the same basin.
(4)
Onshore natural gas transmission
						compression.
Onshore natural gas transmission compression means any
						stationary combination of compressors that move natural gas from production
						fields, natural gas processing plants, or other transmission compressors
						through transmission pipelines to natural gas distribution pipelines, LNG
						storage facilities, or into underground storage. In addition, a transmission
						compressor station includes equipment for liquids separation, and tanks for the
						storage of water and hydrocarbon liquids. Residue (sales) gas compression that
						is part of onshore natural gas processing plants are included in the onshore
						natural gas processing segment and are excluded from this segment. This
						industry segment also includes all booster stations owned and/or operated by
						the facility owner/operator.
(5)
Underground natural gas storage.
Underground natural gas
						storage means subsurface storage, including depleted gas or oil reservoirs and
						salt dome caverns that store natural gas that has been transferred from its
						original location for the primary purpose of load balancing (the process or
						equalizing the receipt and delivery of natural gas); natural gas underground
						storage processes and operations (including compression, dehydration and flow
						measurement, and excluding transmission pipelines); and all the wellheads
						connected to the compression units located at the facility that inject and
						recover natural gas into and from the underground reservoirs.
(6)
Liquefied natural gas (LNG)
						storage
. LNG storage means onshore LNG storage vessels located above
						ground, equipment for liquefying natural gas, compressors to capture and
						re-liquefy boil-off-gas, recondensers, and vaporization units for
						regasification of the liquefied natural gas.
(7)
LNG import and export
						equipment
. LNG import equipment means all onshore or offshore
						equipment that receives imported LNG via ocean transport, stores LNG,
						re-gasifies LNG, and delivers re-gasified natural gas to a natural gas
						transmission or distribution system in California. LNG export equipment means
						all onshore or offshore equipment that receives natural gas, liquefies natural
						gas, stores LNG, and transfers the LNG via ocean transportation to
						California.
(8)
Natural gas
						distribution.
Natural gas distribution means the distribution
						pipelines and metering and regulating equipment at metering-regulating stations
						that are operated by a Local Distribution Company (LDC) within California that
						is regulated by a public utility commission or that is operated as an
						independent municipally-owned distribution system. This segment also excludes
						customer meters and regulators, infrastructure, and pipelines (both interstate
						and intrastate) delivering natural gas directly to major industrial users and
						farm taps upstream of the local distribution company inlet.
