Section 20. Definitions

In addition to the definitions incorporated by reference, the following words and terms shall have, for the purpose of this chapter, the following meanings:

"ASTM" means the American Society for Testing and Materials.

"CCB" means coal combustion byproducts.

"Closure" means the act of securing a fossil fuel combustion products site pursuant to the requirements of this chapter.

"Coal combustion byproducts" or "CCB" means residuals, including fly ash, bottom ash, boiler slag, and flue gas emission control waste produced by burning coal. CCB includes both CCR and non-CCR wastes identified by this definition.

"Coal combustion residuals" or "CCR" means fly ash, bottom ash, boiler slag, and flue gas desulfurization materials generated from burning coal for the purpose of generating electricity by electric utilities and independent power producers. CCR is a specific type of CCB.

"Department" means the Department of Environmental Quality.

"Director" means the Director of the Department of Environmental Quality or the Director of the Department of Mines, Minerals and Energy depending on the context.

"Fossil fuel combustion products" means coal combustion byproducts as defined in this regulation, coal combustion byproducts generated at facilities with fluidized bed combustion technology, petroleum coke combustion byproducts, byproducts from the combustion of oil, byproducts from the combustion of natural gas, and byproducts from the combustion of mixtures of coal and "other fuels" (i.e., co-burning of coal with "other fuels" where coal is at least 50% of the total fuel). For purposes of this definition, "other fuels" means waste-derived fuel product, auto shredder fluff, wood wastes, coal mill rejects, peat, tall oil, tire-derived fuel, deionizer resins, and used oil.

"Fossil fuel combustion products site" means all land and structures, other appurtenances, and improvements on them used to manage fossil fuel combustion products by the methods included in either 9VAC20-85-40 A or B.

"Perennial stream" means a stream or part of a stream that flows continuously during all of the calendar year as a result of groundwater discharge or surface runoff.

"Speculatively accumulated material" means any material that is accumulated before being used, reused, or reclaimed or in anticipation of potential use, reuse, or reclamation. Fossil fuel combustion products are not being accumulated speculatively when they can be used, reused, or reclaimed, have a feasible means of use, reuse, or reclamation available and 75% of the accumulated fossil fuel combustion products are being removed from the storage annually.

"TCLP" means a chemical analytical procedure described in the Virginia Hazardous Waste Management Regulations, 9VAC20-60.

"Waste derived fuel product" means a solid waste or combination of solid wastes that have been treated (altered physically, chemically, or biologically) to produce a fuel product with a minimum heating value of 5,000 BTU/lb. Solid wastes used to produce a waste derived fuel product must have a heating value, or act as binders, and may not be added to the fuel for the purpose of disposal. Waste ingredients may not be listed or characteristic hazardous wastes. The fuel product must be stable at ambient temperature, and not degraded by exposure to the elements. This material may not be "refuse derived fuel (RDF)" as defined in 9VAC5-40-890.
