Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) Actual
					 Emissions: The estimated discharge of pollutants or pollutant precursors into
					 the air, expressed in tons per day.
(b) Anthropogenic Emissions: Emissions
					 originating from human activity or contrivances.
(c) Backcasting: The use of current emissions
					 data and estimation methods to produce emission inventories for previous
					 years.
(d) Baseline Emission
					 Inventory Forecast: The estimated actual, anthropogenic emission inventory for
					 every third year after 1991 (1994, 1997, 2000, et cetera) for each
					 nonattainment pollutant or precursor, as determined by the state board in
					 consultation with the district. Such forecasts shall be based upon the baseline
					 emission inventory and shall take into consideration growth projections and
					 control factors for all adopted emission control measures.
(e) Baseline Emission Inventory: The
					 estimated actual, anthropogenic emissions of each nonattainment pollutant or
					 its precursors, which occurred during calendar year 1987, adjusted for temporal
					 variations in emission rates that result from differences in emission producing
					 activities or climatic factors, as determined by the state board in
					 consultation with the district.
(f)
					 Calculated Emission Inventory Target: The baseline emission inventory for each
					 nonattainment pollutant or precursor, minus the product of the baseline
					 emission inventory times five percent (0.05) times the number of years since
					 1987, expressed in tons per day; i.e. Baseline - [Baseline x 0.05 (year -
					 1987)].
(g) Carrying Capacity: The
					 estimated quantity of nonattainment pollutant emissions or nonattainment
					 precursor emissions that may be emitted daily without causing an exceedence of
					 a state ambient air quality standard in the district, and without causing or
					 contributing to a violation of the state ozone standard in a downwind
					 area.
(h) Credited Emission
					 Reductions: The projected reductions in actual, anthropogenic emissions
					 attributable to the district plan, as compared to the baseline emission
					 inventory forecast for each reporting interval.
(i) Emission Changes: Any increase or
					 decrease in actual emissions from the baseline emission inventory, expressed in
					 tons per day.
(j) Reporting
					 Intervals: The seven year period from 1988 through 1994 and each consecutive
					 three year period thereafter (1995-1997; 1998-2000, 2001-2003; et
					 cetera).
