Code of Maine Rules › 06 - DEPARTMENT OF ENVIRONMENTAL PROTECTION › 096 - DEPARTMENT OF ENVIRONMENTAL PROTECTION - GENERAL › Chapter 100 - DEFINITIONS REGULATION › Section 096-100-125 - Part 70 major source or major stationary source

Current through 2024-29, July 17, 2024
"Part 70 major source or major stationary source" means any
				  stationary source or group of stationary sources as described in paragraphs
				  (A), (B) or (C) of this definition. For purposes of paragraphs (B) and (C),
				  major stationary source includes any group of stationary sources belonging to a
				  single major industrial grouping that is located on one or more contiguous or
				  adjacent properties, and that are under common control of the same person (or
				  persons under common control). For the purposes of defining "major source" in
				  paragraphs (B) or (C) of this definition, a stationary source or group of
				  stationary sources shall be considered part of a single industrial grouping if
				  all of the air pollutant-emitting activities at such source or group of sources
				  on contiguous or adjacent properties are under common control and belong to the
				  same Major Group (i. e. , all have the same two-digit code) as described in the
				  Standard Industrial Classification Manual, 1987. In addition, for purposes of
				  paragraphs (B) and (C) of this definition, any stationary source (or group of
				  stationary sources) that supports another source, where both are under common
				  control of the same person (or persons under common control) and on contiguous
				  or adjacent properties, shall be considered a support facility and part of the
				  same source regardless of the 2-digit SIC code for that support facility. A
				  stationary source (or group of stationary sources) is considered a support
				  facility to a source if at least fifty percent (50%) of the output of the
				  support facility is dedicated to the source.
A.
				 Any major source under Section
				112 of the CAA (relating to
				hazardous air pollutants), which is defined as follows:
(1) For air pollutants other than
				radionuclides, 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, ten (10) tons per year
				(tpy) or more of any single hazardous air pollutant (HAP), (including any
				fugitive emissions of such pollutant) which was listed pursuant to Section
				112(b) of the CAA,
				25 tpy or more of any combination of such HAP (including any fugitive emissions
				of such pollutants), or such lesser quantity as the EPA may establish by rule.
				Notwithstanding the preceding sentence, emissions from any oil or gas
				exploration or production well (with its associated equipment) and emissions
				from any pipeline compressor or pump station shall not be aggregated with
				emissions from other similar units, whether or not such units are in a
				contiguous area or under common control, to determine whether such emissions
				units or sources are major sources; or
(2) For radionuclides, Part 70 major source
				shall have the meaning specified in rules promulgated by the EPA.
