Texas Administrative Code › Title 30 - ENVIRONMENTAL QUALITY › Part 1 - TEXAS COMMISSION ON ENVIRONMENTAL QUALITY › Chapter 101 - GENERAL AIR QUALITY RULES › Subchapter H - EMISSIONS BANKING AND TRADING › Division 1 - EMISSION CREDIT PROGRAM › Section 101.300 - Definitions

Current through Reg. 49, No. 28; July 12, 2024
Unless specifically defined in the Texas Clean Air Act or
						in §
											3.2 or
						§
											101.1 of
						this title (relating to Definitions), the terms used by the commission have the
						meanings commonly ascribed to them in the field of air pollution control. In
						addition, the following words and terms, when used in this division, have the
						following meanings, unless the context clearly indicates otherwise.
(1) Activity--The amount of activity at a
					 facility or mobile source measured in terms of production, use, raw materials
					 input, vehicle miles traveled, or other similar units that have a direct
					 correlation with the economic output and emission rate of the facility or
					 mobile source.
(2) Actual
					 emissions--The total emissions during a selected time period, using the
					 facility's or mobile source's actual daily operating hours, production rates,
					 or types of materials processed, stored, or combusted during that selected time
					 period.
(3) Area source--Any
					 facility included in the agency emissions inventory under the area source
					 category.
(4) Baseline
					 emissions--The facility's emissions, in tons per year, before implementation of
					 an emission reduction calculated as the lowest of the facility's historical
					 adjusted emissions or state implementation plan emissions.
(5) Certified--Any emission reduction that is
					 determined to be creditable upon review and approval by the executive
					 director.
(6) Curtailment--A
					 reduction in activity level at any facility or mobile source.
(7) Emission credit--An emission reduction
					 credit or mobile emission reduction credit.
(8) Emission rate--The facility's rate of
					 emissions per unit of activity.
(9)
					 Emission reduction--A reduction in actual emissions from a facility or mobile
					 source.
(10) Emission reduction
					 credit--A certified emission reduction, expressed in tenths of a ton per year,
					 that is created by eliminating future emissions and quantified during or before
					 the period in which emission reductions are made from a facility.
(11) Emission reduction strategy--The method
					 implemented to reduce the facility's or mobile source's emissions beyond that
					 required by state or federal law, regulation, or agreed order.
(12) Facility--As defined in §
											116.10 of
					 this title (relating to General Definitions). Original equipment and
					 replacement-in-kind equipment that are the same or functionally equivalent are
					 considered the same facility. For the purpose of generating an emission
					 reduction credit at an area source, multiple emissions points with common
					 characteristics may be grouped in order to be considered as a single unit
					 equivalent to a facility as long as the total grouping has emissions equal to
					 or greater than 0.1 tons per year (tpy), even if emission points within the
					 group have emissions of less than 0.1 tpy.
(13) Generator--The owner or operator of a
					 facility or mobile source that creates an emission reduction.
(14) Historical adjusted emissions--The
					 emissions occurring before implementation of an emission reduction strategy and
					 adjusted for any local, state, or federal requirement, calculated using the
					 following equation.

(15) Mobile emission reduction
					 credit--A certified emission reduction from a mobile source or group of mobile
					 sources, expressed in tenths of a ton per year, that is created by eliminating
					 future emissions and quantified during or before the period in which reductions
					 are made from that mobile source or group of mobile sources.
(16) Mobile source--A source included in the
					 agency's emissions inventory under the mobile source category.
(17) Mobile source baseline activity--The
					 level of activity of a mobile source based on an estimate for each year for
					 which the credits are to be generated. After the initial year, the annual
					 estimates should reflect:
(A) the change in
					 the mobile source emissions to reflect any deterioration in the emission
					 control performance of the participating source;
(B) the change in the number of mobile
					 sources resulting from normal retirement or attrition, and the replacement of
					 retired mobile sources with newer and/or cleaner mobile sources;
(C) the change in usage levels, hours of
					 operation, or vehicle miles traveled in the participating population;
					 and
(D) the change in the expected
					 useful life of the participating population.
