9VAC5-40-890. Definitions.

A. For the purpose of the Regulations for the Control and Abatement of Air Pollution and subsequent amendments or any orders issued by the board, the words or terms shall have the meanings given them in subsection C of this section.

B. As used in this article, all terms not defined here shall have the meanings given them in 9VAC5 Chapter 10 (9VAC5-10-10 et seq.), unless otherwise required by context.

C. Terms defined.

"Capacity factor" means the ratio of the average load on a machine or equipment for the period of time considered to the capacity rating of the machine or equipment.

"Fossil-fuel fired steam generator" means furnace or boiler, or both, used in the process of burning fossil fuel for the primary purpose of providing steam by heat transfer.

"Fuel burning equipment" means any furnace, with fuel burning equipment appurtenances thereto, used in the process of burning fuel for the primary purpose of producing heat to be utilized by indirect heat transfer, or by indirect production of power. This includes facilities that are designed as boilers to produce steam or heated water and are designed to burn either fossil fuel or refuse derived fuel. It does not include such facilities if designed primarily to burn raw refuse. This includes fuel burning equipment units (both permanently installed units and portable units) used to replace the power used by mobile sources. For the purposes of this article, stationary combustion turbines are considered to be fuel burning equipment.

"Fuel burning equipment installation" means all fuel burning equipment units within a stationary source in operation prior to October 5, 1979.

"Heat input" means the total gross calorific value of all fuels burned.

"Rated capacity" means the capacity as stipulated in the purchase contract for the condition of 100% load, or such other capacities as mutually agreed to by the board and owner using good engineering judgment.

"Refuse derived fuel (RDF)" means fuel produced from solid or liquid waste (includes materials customarily referred to as refuse and other discarded materials), or both, which has been segregated and classified, with the useable portions being put through a size reduction and classification process which results in a relatively homogeneous mixture.

"Stationary combustion turbine" means any air-breathing internal combustion engine consisting of an air compressor, combustion chamber, and a turbine wheel.

"Stationary internal combustion engine" means an engine in which fuel is burned within a machine in which energy is converted directly into mechanical motion or work. The energy is used directly for the production of power, locomotion or work. Internal combustion engines include, but are not limited to, diesel engines, gasoline engines, and diesel pumps. For the purposes of this article, stationary combustion turbines are not considered to be stationary internal combustion engines.

"Total capacity" means with reference to a fuel burning equipment installation, the sum of the rated capacities (expressed as heat input) of all units of the installation which must be operated simultaneously under conditions of 100% use load.
