New Mexico Administrative Code › Title 20 - ENVIRONMENTAL PROTECTION › Chapter 2 - AIR QUALITY (STATEWIDE) › Part 72 - CONSTRUCTION PERMITS › Section 20.2.72.300 - DEFINITIONS

Current through Register Vol. 35, No. 13, July 16, 2024
In addition to the definitions in
				  20.2.72.7
				  NMAC, the following definitions apply to 20.2.72.300 NMAC - 20.2.72.399
				  NMAC:
A. "Compressor station" means a
				facility whose primary function is the extraction of crude oil, natural gas, or
				water from the earth with compressors, or movement of any fluid, including
				crude oil or natural gas, or products refined from these substances through
				pipelines or the injection of natural gas or CO2 back into the earth using
				compressors. A compressor station may include engines to generate power in
				conjunction with the other functions of extraction, injection or transmission
				and may contain emergency flares. A compressor station may have auxiliary
				equipment which emits small quantities of regulated air contaminants, including
				but not limited to, separators, de-hydration units, heaters, treaters and
				storage tanks, provided the equipment is located within the same property
				boundaries as the compressor engine.
B. "Good engineering practice stack height"
				means HsubGEP = H + 1.5L, where H equals the height of any building or
				obstruction within 5L of the stack, and L equals the lesser of the height or
				maximum projected width of the building or obstruction.
C. "Impact area" means the circular area with
				a radius extending from the source to the most distant point where the total
				potential emissions from the facility will cause a significant ambient impact
				(i.e., equal or exceed the applicable significant ambient impact level in
				20.2.72.500 NMAC.
D. "Maximum
				projected width" means the largest crosswind building or obstruction
				dimension.
E. "Potential to emit"
				or "potential emissions" means the maximum capacity of a stationary source to
				emit a regulated air contaminant under its physical and operational design. Any
				physical or operational limitation on the capacity of the source to emit a
				regulated air contaminant, including air pollution control equipment and
				restrictions on hours of operation or on the type or amount of material
				combusted, stored, or processed, shall be treated as part of its design if the
				limitations or the effect it would have on emissions is federally enforceable.
				Secondary emissions do not count in determining the potential to emit of a
				stationary source.
F. "Secondary
				emissions" means emissions of an air contaminant which occur as a result of the
				construction or operation of a stationary source or modification, but do not
				come from the stationary source or modification itself. Secondary emissions
				must be specific, well defined, quantifiable, and impact the same general areas
				as the stationary source or modification which causes the secondary emissions.
				Secondary emissions include emissions from any offsite support facility which
				would not be constructed or increase its emissions except as a result of the
				construction or operation of the stationary source or modification. Secondary
				emissions do not include any emissions which come directly from a mobile
				source, such as emissions from the tailpipe of a motor vehicle, from a train,
				or from a vessel.
G. "SUM" means
				the sum of the potential emissions for oxides of nitrogen from all adjacent
				sources.
H. "SUM15" means the sum
				of the potential emissions for oxides of nitrogen from all adjacent sources
				within 15 km of the NO2 impact area.
I. "SUM25" means the sum of the potential
				emissions for oxides of nitrogen from all adjacent sources within 25 km of the
				NO2 impact area.
J. "Sweet natural
				gas" means natural gas containing no more than 0.25 grains of hydrogen sulfide
				per 100 standard cubic feet of gas.
