A. For the purpose of these regulations 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.

"Aluminum production operation" means the production of aluminum or aluminum alloys from aluminum pigs, foundry returns or scrap material by smelting or melting to the metallic form. Includes fluxing, alloying, degassing, and demagging operations.

"Brass or bronze" means any metal alloy containing copper as its predominant constituent and lesser amounts of zinc, tin, lead or other metals.

"Brass or bronze production" means the production of brass or bronze ingots from scrap material by, or through a combination of, melting, smelting, refining or alloying.

"Ferroalloy production operation" means the production of any ferroalloy by use of a smelting furnace.

"Gray iron foundry operation" means the production of gray iron castings by use of a melting furnace.

"Lead" means elemental lead or alloys in which the predominant component is lead.

"Magnesium production operation" means the production of magnesium from scrap material by use of a furnace.

"Melt time" means the time in which the metal is melting and available at the spout or tap hole, excluding any time the equipment is idle, preheating or preparing for shutdown.

"Primary copper smelter" means any installation or any intermediate process engaged in the production of copper from copper sulfide ore concentrates through the use of pyrometallurgical techniques.

"Primary lead smelter" means any installation or any intermediate process engaged in the production of lead from lead sulfide ore concentrates through the use of pyrometallurgical techniques.

"Primary metal operation" means any operation which involves the production of a metal from metal ore concentrates through the use of pyrometallurgical techniques.

"Primary zinc smelter" means any installation or any intermediate process engaged in the production of zinc or zinc oxide from zinc sulfide ore concentrates through the use of pyrometallurgical techniques.

"Process operation" means any method, form, action, operation or treatment of manufacturing or processing, including any storage or handling of materials or products before, during or after manufacturing or processing.

"Process unit" means any step in a manufacturing or process operation which results in the emission of pollutants to the atmosphere.

"Process weight" means the total weight of all materials introduced into any process unit which may cause any emission of pollutants. Process weight includes solid fuels charged, but does not include liquid and gaseous fuels charged or combustion air for all fuels.

"Process weight rate" means a rate established as follows:

a. For continuous or long-run steady-state process operations, the total process weight for the entire period of continuous operation or for a typical portion of it, divided by the number of hours of such period or portion of it.

b. For cyclical or batch process operations, the total weight for a period that covers a complete operation or an integral number of cycles, divided by the hours of actual process operation during such a period.

"Secondary lead production operation" means the production of lead from lead bearing scrap material by smelting to the metallic form.

"Secondary metal operation" means any aluminum production operation, brass or bronze production operation, ferroalloy production operation, gray iron foundry operation, secondary lead production operation, magnesium production operation, steel foundry operation or zinc process operation.

"Steel foundry operation" means the production of steel castings by use of a melting furnace.

"Zinc process operation" means zinc reclaiming, zinc oxide manufacturing and zinc galvanizing.
