			 section.
(15) "Maximum demonstrated
			 particulate matter control device temperature" means the highest 4-hour block
			 average flue gas temperature measured at the particulate matter control device

			 subsection (c) of this section.
(16) "mg/dscm" means milligrams of air
			 pollutant per dry standard cubic meter.
(17) "Modification" means "modification or
			 modified municipal waste combustor unit" as defined in
			 40

(19) "Municipal waste combustor," "municipal
			 waste combustor unit" or "MWC" means any part or activity of any stationary
			 source which part or activity emits or has the potential to emit any regulated
			 air pollutant or any hazardous air pollutant, exclusive of associated air
			 pollution control equipment, that combusts municipal solid waste, inclusive of
			 those emissions units constructed prior to January 1, 2007 combusting a
			 single-item waste stream of tires. Combustors that combust landfill gases
			 collected by landfill gas collection systems are not municipal waste
			 combustors.
(20) "Municipal waste
			 combustor plant" or "plant" means any premises at which one or more municipal
			 waste combustor units are situated.
(21) "Municipal waste combustor unit load"
			 means the rate at which steam is produced at a municipal waste combustor

			 "ng/dscm" means nanograms of air pollutant per dry standard cubic
			 meter.

			 grouping of all stationary sources at any one location and owned by or under
			 the control of the same person or persons.
