Tenn. Comp. R. & Regs. 1200-03-31-.02 - DEFINITIONS

The following definitions are applicable to this chapter:

(1) "Major Source" means any stationary source or group of stationary sources located within a contiguous area and under common control that emits or has the potential to emit considering controls, in the aggregate, 10 tons per year or more of any hazardous air pollutant or 25 tons per year of any combination of hazardous air pollutants. In addition, the provisions of subpart (11)(b)14.(i) of Rule 1200-03-09-.02 are recognized as to the grouping or aggregation of emissions for the purpose of calculating emission potential as it relates to the applicability thresholds of this definition. Additionally, electric utility steam generating units will not be regulated as major sources until the United States Environmental Protection Agency decides that they should be so regulated pursuant to Section 112(n) of the Federal Clean Air Act.

(2) "Area Source" means any stationary source of hazardous air pollutants that is not a major source. Mobile sources such as vehicles, trains, planes, ships, et cetera are not area sources.

(3) "New Source" means a stationary source that emits hazardous air pollutants as they are defined in this paragraph and is constructed or reconstructed on or after the date that the United States Environmental Protection Agency approves the major source operating permit program submitted by the State of Tennessee in accordance with Section 502(d) of the Federal Clean Air Act.

(4) "Stationary Source" shall have the meaning given to it in subparagraph (1)(ddd) of Rule 1200 03-02-.01.

(5) "Existing Source" is any stationary source that emits hazardous air pollutants as they are defined in paragraph (6) of this rule and is not a new source.
