Definitions

The following words and terms when used in this Subchapter shall have the following meaning unless the context clearly indicates otherwise: "Actual emissions" means the total amount of any regulated air pollutant actually emitted from a given facility during a particular calendar year, determined using methods contained in 252:100-5-2.1(d). "Allowable emissions" means: (A) The total amount of any regulated air pollutant emitted based on limits contained in an enforceable permit or potential to emit, or (B) For grandfathered sources, emission limits based on maximum design capacity and considering all applicable rules. "Consumer Price Index" means an index determined by the U.S. Department of Labor measuring the change in the cost of typical wage-earner purchases of goods and services expressed as a percentage of the cost of these same goods and services in a base period. "Date of billing" means the date the fee was billed. In the case no fee was billed because the owner or operator failed to submit the required annual emission inventory, the date of billing shall mean the date on which the fee would have been billed had the emission inventory been submitted when due. "Emission inventory" means a compilation of all point source, storage and process fugitive air emissions for all regulated air pollutants at a given facility. "Error" means, with regard to fees, a fee overpayment made as a result of a mistake on the part of the DEQ in invoicing or the part of the owner or operator in calculating emissions. It does not mean a mistake made in the decision to use or not to use a particular emission factor or method of calculation. "Grandfathered source" means a stationary source that was in operation in Oklahoma when an otherwise applicable rule was promulgated unless that rule specifically applies to existing sources or the source has undergone modification since that rule was promulgated. "Minor facility" means a facility which is not a Part 70 source. "Process Fugitive Emissions" means those emissions created by or incidental to any particular process which become airborne or have the potential to become airborne, and could not reasonably, taking into account economic considerations, be made to pass through a stack, chimney, vent or other functionally equivalent opening. "Regulated air pollutant (for fee calculation)", which is used only for purposes of this Subchapter, means any "regulated air pollutant" except the following: (A) Carbon monoxide. (B) Gross particulate matter (GPM). (C) Greenhouse gases (GHGs) either as individual pollutants or as an aggregate. 2024_Oct_AQAC_SC_5_7_8_RUL_Presented 2 October 15, 2024
