Type 'c' means any hand-fired or stoker-fired fuel burning unit not classified as a Type 'a' unit.2.11. "Fugitive Particulate Matter" means any and all particulate matter generated by any operation involving or associated with the combustion of fuel in fuel burning units which, if not confined, would be emitted directly into the open air from points other than a stack outlet.2.12. "Fugitive Particulate Matter Control System" means any equipment or method used to confine, collect or dispose of fugitive particulate matter, including, but not limited to, hoods, bins, duct work, fans and air pollution control equipment.2.13. "Heat Input" means the rate of heat release from all fuels fired in all similar units vented by the test stack during the test run period.2.13.1. "Design Heat Input (DHI)" means the heat input level (in MM Btu/hr) for which an individual fuel burning unit has been designed to be operated during continuous operation.2.13.2. "Total Design Heat Input (TDHI)" means the sum of the design heat inputs for all similar units located at one plant.2.13.3. "Normal Maximum Operating Load (NMOL)" means the sum of the Design Heat Input levels (in MM Btu/hr) of the similar unit(s) vented by the test stack, unless the owner/operator has elected to operate one or more of the similar units vented by the test stack at or below a specified percentage of its Design Heat Input level as part of a compliance program, permit or consent order officially accepted by the Secretary. In such event, the NMOL is the sum of the Design Heat Input levels or fractions thereof as appropriate (i.e., NMOL = 0.75 DHI1 + DHI2).2.14. "Indirect Heat Exchanger" means a device that combusts any fuel and produces steam or heats water or any other heat transfer medium. This term includes any duct burner that combusts fuel and is part of a combined cycle system. This term does not include process heaters as defined in subsection 2.26.2.15. "Laboratory Official" means the person, qualified by experience or education, who is charged with overseeing or conducting the laboratory analysis of the collected samples. This person is responsible for ensuring the accuracy and validity of the laboratory results.2.16. "Malfunction" means a sudden and unavoidable breakdown of process or control equipment.2.17. "Natural Gas" means (1) 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, or(2) liquefied petroleum (LP) gas, as defined by the American Society for Testing and Materials in ASTM D1835-97, "Standard Specification for Liquefied Petroleum Gases".2.18. "Normal Operation" when used in the context of fuel quality and combinations fired, means the type, quality and combination of fuel(s) fired which is representative of the fuel or fuel combination fired, in the unit(s) tested, over a reasonable period prior to the test, and the fuel or fuel combination which might reasonably be expected to continue to be fired in this unit after the test. If the type of fuel, quality or combination used in the unit is variable, use the type, quality and/or combination fired in day-to-day operation which can reasonably be expected to produce the greatest particulate matter loading to the control equipment (e.g., if coal is fired eight months out of the year and gas is fired four months out of the year, coal is to be burned during the test).2.19. "Opacity" means the degree to which emissions reduce the transmission of light and obscure the view of an object in the background.2.20. "Owner or Operator" means the person responsible for the compliance of the fuel burning units subject to the provisions of 45CSR2.2.21. "Particulate Matter" means any material, except uncombined water, that exists in a finely divided form as a liquid or solid.2.22. "Person" means any and all persons, natural or artificial, including the state of West Virginia or any other state, the United States of America, any municipal, statutory, public or private corporation organized or existing under the laws of this or any other state or country, and any firm, partnership or association of whatever nature.2.23. "Plant" means and includes all fuel burning units, source operations, equipment and grounds utilized in an integral complex.2.24. "Prefilter" means a filter used in the sampling train prior to the primary filter for the purpose of reducing the particulate matter build-up on the primary filter.2.25. "Primary Filter" means the last filter used in the sampling train to separate the particulate matter sample from the sampled stack gas.2.26. "Process Heater" means a device that is primarily used to heat a material to initiate or promote a chemical reaction in which the material participates as a reactant or catalyst.2.27. "Probe" means the part of the pitot tube assembly (nozzle, sample tube, pitot tube, filter holder(s), sensor(s)), which precedes the last filter in the sampling train and conveys the sample gas and particulate matter from the nozzle inlet to the last filter disc used for collecting stack particulate matter.2.28. "Residual Oil" means crude oil, fuel oil that does not comply with the specifications under the definition of distillate oil, and all fuel oil numbers 4, 5 and 6, as defined by the American Society for Testing and Materials in ASTM D396-98, "Standard Specification for Fuel Oils".2.29. "Sampling Plane" means the imaginary plane located perpendicular to the gas flow in the duct or stack at the place selected for the extraction of the required samples.2.30.
