Section 10 CSR 10-6.020 - Definitions and Common Reference Tables

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been added into their applicable rule(s), the terms are already defined in statute, or the applicable rule(s) have been rescinded.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.

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

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

8. Volatile organic liquid-Any substance which is a liquid at storage conditions and which contains one (1) or more volatile organic compounds as defined in this rule.

9. Volatility-For purposes of 10 CSR 10-5.540, low volatility materials are defined as those which have a vapor pressure less than or equal to seventy-five (75) mmHg at twenty degrees Celsius (20 °C), moderate volatility materials have a vapor pressure greater than seventy-five (75) and less than or equal to one hundred fifty (150) mmHg at twenty degrees Celsius (20 °C), and high volatility materials have a vapor pressure greater than one hundred fifty (150) mmHg at twenty degrees Celsius (20 °C).
