(a)

Class I, meaning any regulated toxic air pollutant recognized by the United States Environmental Protection Agency as a Group A-Human Carcinogen or Group B-Probable Human Carcinogen, as referenced in 51 Federal Register 34,000 (1986), or otherwise designated a regulated toxic air pollutant-Class I by the commissioner pursuant to rules adopted under RSA 125-I:3.

Copy link

(b)

Class II, meaning any regulated toxic air pollutant other than a regulated toxic air pollutant Class I, which is recognized by the United States Environmental Protection Agency as a Group C-Possible Human Carcinogen, as referenced in 51 Federal Register 34,000 (1986), or otherwise designated a regulated toxic air pollutant-Class II by the commissioner pursuant to rules adopted under RSA 125-I:3.

Copy link

(c)

Class III, meaning any regulated toxic air pollutant other than a regulated toxic air pollutant-Class I or Class II.

Copy link

XV.

"Stationary source" means any building, structure, facility, or installation that emits or may emit a regulated toxic air pollutant or air contaminant into the ambient air.

Copy link

XVI.

"Threshold limit value" means the threshold limit value-time weighted average (TLV-TWA) as set forth in the American Conference of Governmental Industrial Hygienists (ACGIH) 1995 list and as amended thereafter.

Copy link

XVII.

"Uncontrolled emission" means any emission of a regulated toxic air pollutant from a device or process at a stationary source that is not subject to treatment or removal by pollution control equipment prior to being emitted to the ambient air, or is emitted to the ambient air in amounts which have not been limited by conditions in an enforceable permit or document.
