(b) Pursuant to Env-A 1411.01, the list naming all regulated toxic air pollutants and other information shall be as set forth in Table 1450-1, below:
a. !supportLists?a.
A Toxicity Classification as classified in Env-A 1407, in general:
Toxicity Class I: Classification established pursuant to Env-A 1407.02.
Toxicity Class II: Classification established pursuant to Env-A 1407.03.
Toxicity Class III: Classification established pursuant to Env-A 1407.04.
B Ambient air limit.
C De minimis values were calculated using non-rounded AALs. The AALs and de minimis values represented in this table are rounded to whole numbers or 2 significant figures if less than 10.
E Denotes regulated toxic air pollutants which have data limitations preventing derivation of AALs in accordance with Env-A 1411.

III-a. "Biomass'' means organic matter used as a fuel, not including wood derived from construction and demolition debris, as defined in RSA 149-M:4, IV-a; wood which has been chemically treated; or agricultural crops or aquatic plants or byproducts from such crops or plants, which have been used to rehabilitate a contaminated or brownfields site through a process known as "phytoremediation.''
RSA 125-I:2
VI. "Compliance boundary'' means the boundary of the property on which the stationary source is located or an alternate compliance boundary determined by the department in accordance with rules adopted pursuant to this chapter.
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.
