Ohio Administrative Code › Title 3745 - Ohio Environmental Protection Agency › Chapter 3745-18 - Sulfur Dioxide Regulations › Section 3745-18-01 - Definitions and incorporation by reference

Current through all
			 regulations passed and filed through July 1, 2024
(A) Except as otherwise provided in paragraph
			 (B) of this rule, the definitions in rule
			 3745-15-01 of the
			 Administrative Code  apply to this
			 chapter.
(B) The following
			 definitions  apply exclusively to this
			 chapter:
(1) "By-product coke oven gas" means
			 the gas produced during the production of metallurgical coke in slot-type,
			 by-product coke ovens.
(2)
			 "Calendar day" means the period of twenty-four hours from midnight to
			 midnight.
(3) "First quarter" means
			 January, February and March.
(4)
			 "Fuel burning equipment" or "fossil fuel fired steam generator" means any
			 furnace, boiler, apparatus, stack, and all appurtenances thereto, used in the
			 process of burning fuel for the primary purpose of producing heat or power by
			 indirect heat transfer.
(5) "Fossil
			 fuel" means natural gas, coke oven gas, petroleum, coal and any form of solid,
			 liquid, or gaseous fuel derived from such materials.
(6) "Fourth quarter" means October, November
			 and December.
(7) "Incinerator"
			 means any equipment, machine, device, article, contrivance, structure, or part
			 of a structure used to burn refuse or to process refuse material by burning
			 other than by open burning.
(8) "MM
			 Btu" means millions of British thermal units.
(9) "Natural gas" means a naturally occurring
			 mixture of hydrocarbon and nonhydrocarbon gases found in geologic formations
			 beneath the earth's surface, of which the principal constituent is
			 methane.
(10) "Owner or operator"
			 means any person who owns, leases, operates, controls, or supervises a
			 facility, building, structure, or installation which directly or indirectly
			 results or may result in emissions of sulfur dioxide.
(11) "OEPA" means the Ohio environmental
			 protection agency.
(12) "Primary
			 zinc smelter" means any installation engaged in the production of zinc or zinc
			 oxide from zinc sulfide ore concentrates through the use of pyrometallurgical
			 techniques.
(13) "Process" means
			 any source operation including any equipment, devices, or contrivances and all
			 appurtenances thereto, for changing any material whatever or for storage or
			 handling of any material, the use of which may cause the discharge of an air
			 contaminant into the open air, but not including that equipment defined as a
			 fossil fuel fired steam generator.
(14) "Process weight" means the total weight
			 of all materials introduced into the source operation including solid fuels,
			 but excluding gaseous fuels and liquid fuels when they are used solely as fuels
			 and excluding air introduced for the purpose of combustion.
(15) "Rated capacity" or "rated heat input
			 capacity" means the maximum capacity guaranteed by the equipment manufacturer
			 or the maximum normally achieved during use as determined by the director,
			 whichever is greater.
(16) "Run"
			 means the net period of time during which an emission sample is collected.
			 Unless otherwise specified, a run may be either intermittent or continuous
			 within the limits of good engineering practice as determined by the
			 director.
(17) "Second quarter"
			 means April, May and June.
(18)
			 "Stationary gas turbine" means an engine in which a turbine is driven by
			 expanding hot combustion gases. Such an engine typically consists of an
			 axial-flow air compressor, one or more combustion chambers, and the
			 turbine.
(19) "Stationary internal
			 combustion engine" means a stationary engine in which combustion occurs within
			 one or more cylinders, converting heat energy into mechanical energy, which in
			 turn drives an electric generator or other mechanical equipment.
(20) "Sulfur recovery plant" means any plant
			 that recovers elemental sulfur from any gas stream.
(21) "Sulfuric acid production unit" means
			 any facility producing sulfuric acid by the contact process by burning
			 elemental sulfur, alkylation acid, hydrogen sulfide, organic sulfides and
			 mercaptans, or acid sludge.
(22)
			 "Third quarter" means July, August and September.
(23) "Total rated capacity" means the sum of
			 the rated capacities of all fuel burning equipment connected to a common
			 stack.
