Missouri Code of State Regulations › Title 10 - DEPARTMENT OF NATURAL RESOURCES › Division 10 - Air Conservation Commission › Chapter 6 - Air Quality Standards, Definitions, Sampling and Reference Methods and Air Pollution Control Regulations for the Entire State of Missouri › Section 10 CSR 10-6.020 - Definitions and Common Reference Tables

Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: The primary purpose of this amendment is to
				  remove definitions that are no longer needed, either because the definitions
				  have been added into their applicable rule(s), the terms are already defined in
				  statute, or the applicable rule(s) have been rescinded. Additionally, the list
				  of Hazardous Air Pollutants and Exempt Volatile Organic Compounds will be
				  updated to match the current lists dictated in the Clean Air Act section
				  112(b)(1) and  40 CFR 51.100(s), respectively.
(1) Applicability. This rule shall apply
				throughout Missouri defining terms and expressions used in all Title 10,
				Division 10- Air Conservation Commission rules. If a definition in this rule
				conflicts with a definition in any other 10 CSR 10 rule, the definition in
				10 CSR
				10-6.020 shall take precedence with the exception that
				federal definitions incorporated by reference into a 10 CSR 10 rule take
				precedence over definitions in
				10 CSR
				10-6.020.
(2) Definitions.
(A) All terms beginning with A.
1. Account holder-Any person that chooses to
				participate in the emission reduction credit (ERC) program by generating,
				buying, selling, or trading ERCs.
2. Acid rain emissions limitation-As defined
				in  40 CFR 72.2, a limitation on emissions of sulfur dioxide or nitrogen oxides
				under the Acid Rain Program under Title IV of the Clean Air Act.
3. Act-The Clean Air Act,  42 U.S.C. 7401.
				References to the word Title pertain to the titles of the Clean Air Act
				Amendments of 1990,  P.L. 101-549.
4. Active collection system-A gas collection
				system that uses gas mover equipment.
5. Active landfill-A landfill in which solid
				waste is being placed or a landfill that is planned to accept waste in the

6. Activity level-Defined
				as follows:
A. For the purpose of 10 CSR
				10-6.410, the amount of activity at a 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 of the source and is not
				affected by changes in the emissions rate (i.e., mass per unit of activity);
				and
B. For all other purposes, the
				measurable factor or parameter that relates directly or indirectly to the
				emissions of an air pollution source. Depending on the source category,
				activity information includes but is not limited to the amount of fuel
				combusted, raw material processed, product manufactured, or material handled or
				processed.
7. Actual
				emissions-The actual rate of emissions of a pollutant from a source operation
				is determined as follows:
A. Actual emissions
				as of a particular date shall equal the average rate, in tons per year, at
				which the source operation or installation actually emitted the pollutant
				during the previous two- (2-) year period and which represents normal
				operation. A different time period for averaging may be used if the director
				determines it to be more representative. Actual emissions shall be calculated
				using actual operating hours, production rates, and types of materials
				processed, stored, or combusted during the selected time period;
B. The director may presume that
				source-specific allowable emissions for a source operation or installation are
				equivalent to the actual emissions of the source operation or installation;
				and
C. For source operations or
				installations, which have not begun normal operations on the particular date,
				actual emissions shall equal the potential emissions of the source operation or
				installation on that date.
8. Adhesive-Any chemical substance that is
				applied for the purpose of bonding two (2) surfaces together other than by
				mechanical means. For the purpose of 10 CSR 10-5.330, an adhesive is considered
				a surface coating.
9.
				Administrator-Defined as follows:
A. For the
				purpose of 10 CSR 10-6.360, the administrator of the U.S. Environmental

				visibility impairment which interferes with the protection, preservation,
				management, or enjoyment of the visitor's visual experience of a Class I area,
				which is an area designated as Class I in 10 CSR 10-6.060(11)(A). This
				determination must be made on a case-by-case basis taking into account the
				geographic extent, intensity, duration, frequency, and time of visibility
				impairments and how these factors correlate with the times of visitor use of
				the Class I area and the frequency and timing of natural conditions that reduce
				visibility.

				repairs in any amount any commercial, civil, or military aerospace vehicle or
				component.

				subject to permitting under Title V of the Act.
16. Affected unit-A unit that is subject to
				emission reduction requirements or limitations under Title IV of the
				Act.

				any air pollutant, to the extent the administrator of the U.S. Environmental
				Protection Agency, or the administrator's duly authorized representative has
				identified such precursor(s) for the particular purpose for which the term air
				pollutant is used.
21. Air
				pollution-The presence in the ambient air of one (1) or more air contaminants
