S.C. Code Regs. § § 61-62.5.5.2.II

Current through Register Vol. 48, No. 10, October 25, 2024

Section 61-62.5.5.2.II - DEFINITIONS

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 NO_X Control: Means an emissions limitation based on the maximum degree of reduction for NO_X 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 NO_X 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 NO_X 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 NO_X 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.

(I) New affected source: Means any affected source which has been constructed after June 25, 2004, or meets the applicability requirements of Section I(A)(3). A new affected source will not be considered an existing affected source at burner assembly replacement under Section I(A)(2).

(J) Non-routine maintenance is an unforeseen failure of a single burner assembly in an existing affected source with multiple burner application forcing an unplanned replacement of the existing burner.

(K) Source: Means a stationary NO_X emission unit, comprised of one or more burners.
