South Carolina Code of Regulations › Chapter 61 - DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL › Subchapter 61-62 - Air Pollution Control Regulations and Standards › Subchapter 61-62.5 - AIR POLLUTION CONTROL STANDARDS › STANDARD NO. 5.2 - CONTROL OF OXIDES OF NITROGEN (NO[x]) › Section 61-62.5.5.2.II - DEFINITIONS

Current through Register Vol. 48, No. 6, June 28, 2024
For the purposes of this regulation, the following
					 definitions shall apply:
(A) Annual
				  Capacity Factor: Means the ratio between the actual heat input to a combustion
				  unit from the fuels during a calendar year and the potential heat input to the
				  steam generating unit had it been operated for 8,760 hours during a calendar
				  year at the maximum steady state design heat input capacity.
(B) Burner Assembly: Means any complete,
				  pre-engineered device that combines air (or oxygen) and fuel in a controlled
				  manner and admits this mixture into a combustion chamber in such a way as to
				  ensure safe and efficient combustion. A self-contained chamber such as is found
				  on a combustion turbine is not a burner assembly for the purposes of this
				  regulation.
(C) Case-by-Case
				  NOX Control: Means an emissions limitation based on the
				  maximum degree of reduction for NOX which would be
				  emitted from any new source which the Department, on a case-by-case basis,
				  taking into account energy, environmental, and economic impacts and other
				  costs, determines is achievable for such source through application of
				  production processes or available methods, systems, and techniques. In no event
				  shall application of NOX control result in emissions of
				  any pollutant which would exceed the emissions allowed by any applicable
				  standard. If the Department determines that technological or economic
				  limitations on the application of measurement methodology to a particular
				  source would make the impositions of an emission standard infeasible, a design,
				  equipment, work practice, operational standard, or combination thereof, may be
				  prescribed instead to satisfy the requirement for the application of
				  NOX control. Such standard shall, to the degree
				  possible, set forth the emissions reduction achievable by implementation of
				  such design, equipment, work practice or operation, and shall provide for
				  compliance by means which achieve equivalent results.
(D) Combustion Control Device: Means, but is
				  not limited to, any equipment that is used to destroy or remove air
				  pollutant(s) prior to discharge to the atmosphere, excluding boilers, process
				  heaters, dryers, furnaces, digesters, ovens, combustors, and similar combustion
				  devices. Such equipment includes, but is not limited to, thermal oxidizers,
				  catalytic oxidizers, and flares.
(E) Constructed: Means the on-site
				  fabrication, erection, or installation of the NOX
				  emitting source.
(F) Equivalent
				  Technology: Means any item that is identical or functionally equivalent to the
				  existing component. This component may serve the same purpose or function as
				  the replaced component, but may be different in some respects or improved in
				  some ways.
(G) Existing affected
				  source: Means sources constructed on or before June 25, 2004, and that meet the
				  applicability requirements of Section I(A)(2).
(H) Fuel: Means the following fuels, any
				  combination of the fuels or any combustible material the Department determines
				  to be a fuel including, but not limited to:
(1) Virgin fuel, waste, waste fuel, and clean
				  wood (biomass fuel) as defined in Regulation 61-62.1.
(2) Biodiesel: Means a mono-alkyl ester
				  derived from vegetable oil and animal fat and conforming to ASTM
				  D6751.
(3) Biofuel: Means any
				  biomass-based solid fuel that is not a solid waste. This includes, but is not
				  limited to, animal manure, including litter and other bedding materials;
				  vegetative agricultural and silvicultural materials, such as logging residues
				  (slash), nut and grain hulls and chaff (for example, almond, walnut, peanut,
				  rice, and wheat), bagasse, orchard prunings, corn stalks, coffee bean hulls and
				  grounds.
(4) Digester gas: Means
				  any gaseous by-product of wastewater treatment typically formed through the
				  anaerobic decomposition of organic waste materials and composed principally of
				  methane and CO2.
(5) Fossil Fuel: Means natural gas,
				  petroleum, coal, and any form of solid, liquid, or gaseous fuel derived from
				  such material for the purpose of creating useful heat. Petroleum for facilities
				  constructed, reconstructed, or modified before May 4, 2011, means crude oil or
				  a fuel derived from crude oil, including, but not limited to, distillate oil
				  and residual oil. For units constructed, reconstructed, or modified after May
				  3, 2011, petroleum means crude oil or a fuel derived from crude oil, including,
				  but not limited to, distillate oil, residual oil, and petroleum coke.
(6) Landfill Gas: Means a gaseous by-product
				  of the land application of municipal refuse typically formed through the
				  anaerobic decomposition of waste materials and composed principally of methane
				  and CO2.
