				seated over the charging ports following removal of the larry car.
2.7. "Charging Operation" means any operation
				or procedure by which coal is introduced into a coke oven. For coke oven
				batteries employing larry cars, the charging operation shall begin when the
				gate(s) on the larry car coal hopper is (are) opened or the mechanical feeders
				start the flow of coal into the first charging port(s) until the oven is
				completely charged and the last charging port lid is seated.
2.8. "Charging Port" means any opening

				Emissions" means any smoke and/or particulate matter emissions from any door
				area including, but not limited to, emissions from the door, chuck door, door
				seal, jamb or refractory.
2.13.
				"Duplicate Source Operation" means any combination of 2 or more individual
				source operations of any size that have the same nomenclature, either formerly
				adopted and/or commonly sanctioned by usage such as, but not limited to, two or
				more rotary driers, basic oxygen furnaces or electric arc furnaces contained in
				the same plant.
2.14. "Ferroalloy
				Electric Submerged Arc Furnace" means any furnace used in production of
				ferroalloys wherein electrical energy is converted to heat energy by
				transmission of current between electrodes partially submerged in the furnace
				charge.
2.15. "Fuel" means any form
				of combustible matter (solid, liquid, vapor or gas) that is used as a source of
				heat.
2.16. "Fugitive Particulate
				Matter" means any and all particulate matter which, if not confined, would be
				emitted directly into the open air from points other than a stack
				outlet.
2.17. "Furnace Charge"
				means any material introduced into a ferroalloy electric submerged arc furnace,
				and may consist of, but is not limited to, ores, slag, carbonaceous material
				and limestone.
2.18. "Maintenance
				Operation" means maintenance activities that have zero process weight rate and
				that are not defined as a manufacturing process.
2.19. "Malfunction" means a sudden and
				unavoidable breakdown of process or control equipment.
2.20. "Manufacturing Process" means any
				action, operation or treatment, embracing chemical, industrial or manufacturing
				efforts, and employing, for example, heat treating furnaces, by-product coke
				plants, core-baking ovens, mixing kettles, cupolas, blast furnaces, open hearth
				furnaces, heating and reheating furnaces, puddling furnaces, sintering plants,
				electric steel furnaces, ferrous and non-ferrous foundries, kilns, stills,
				driers, crushers, grinders, roasters, and equipment used in connection
				therewith and all other methods or forms of manufacturing or processing that
				may emit smoke, particulate matter or gaseous matter.
2.21. "Non-Recovery Coke Production Facility"
				means the destructive distillation of coal in which the gaseous and liquid
				distillates are separated from coal, but not recovered as by-products, and
				includes any on-site coal preparation, charging, coking, coke pushing, hot coke
				transfer, coke quenching and coke handling.
2.22. "Offtake Piping" means the piping that
				transports gaseous by-products of the coking cycle from an oven to the coke
				oven gas collector main, such as standpipes, standpipe caps, goosenecks and
				slipjoints.
2.23. "Opacity" means
				the degree to which emissions reduce the transmission of light and obscure the
				view of an object in the background.
2.24. "Oxygen Lancing" shall mean the burning
				open of a taphole to remove slag or product from the taphole associated with
				operations of a ferroalloy electric submerged arc furnace.
2.25. "Particulate Matter" means any
				material, except uncombined water, that exists in a finely divided form as a
				liquid or solid.

2.30. "Potential To Emit",
				for the purpose of subsections 10.5 and 10.6, means the maximum capacity of a
				source, on an hourly and annual basis, to emit any air pollutant(s) under its
				physical and operational design, prior to any air pollution control
				equipment.
2.31. "Process Weight"
				means that total weight of all materials introduced into a source operation,

				established as follows:
2.32.1. For continuous
				or long-run steady-state source operations, the total process weight for the
				entire period of continuous operation or for a typical portion thereof, divided
				by the number of hours of such period or portion thereof.

				operations, or unit processes, the total process weight for a period that
				covers a complete operation or an integral number of cycles, divided by the
				hours of actual process operation during such a period.

				operation or the design of any equipment is such as to permit more than one
				interpretation of this definition, the interpretation that results in the
				minimum value for allowable emission shall apply.
