Additional optional information:

The scoping period begins after publication in the Federal Register of a Notice of Intent (NOI) to

prepare an EIS. The public scoping process is that portion of the process where the public is invited

to participate. DOE also conducts an early internal scoping process for environmental assessments

(EAs) or EISs. For EISs, this internal scoping process precedes the public scoping process. DOE's

scoping procedures are found in 10 CFR 1021.311.

157. SIEVERT. The SI (International System of Units) unit of radiation dose equivalent. The dose

equivalent in sieverts equals the absorbed dose in grays multiplied by the appropriate quality factor (1

Sv = 100 rem). (See gray.) [Derived from 10 CFR 20.1004]

158. SOLID WASTE.

1. In general, solid wastes are non-liquid, non-soluble discarded materials ranging from municipal

garbage to industrial wastes that contain complex and sometimes hazardous substances. Solid wastes

include sewage sludge, agricultural refuse, demolition wastes, and mining residues. [Derived from

EPA Terms]

2. For purposes of regulation under the Resource Conservation and Recovery Act, solid waste is any

garbage; refuse; sludge from a waste treatment plant, water supply treatment plant, or air pollution

control facility; and other discarded material. Solid waste includes solid, liquid, semisolid, or contained

gaseous material resulting from industrial, commercial, mining, and agricultural operations and from

community activities. Solid waste does not include solid or dissolved material in domestic sewage or

irrigation return flows or industrial discharges which are point sources subject to permits under Section

402 of the Clean Water Act. Finally, solid waste does not include source, special nuclear, or by-

product material as defined by the Atomic Energy Act. A more detailed regulatory definition of solid

waste can be found in 40 CFR 261.2. (See hazardous waste and Resource Conservation and

Recovery Act.) [Derived from RCRA sect. 1004]

159. SOURCE MATERIAL. In general, material from which special nuclear material can be derived.

Under the Atomic Energy Act and Nuclear Regulatory Commission regulations, "source material"

means uranium and thorium in any physical or chemical form, as well as ores which contain one-

twentieth of one percent (0.05%) or more by weight of uranium or thorium. (See special nuclear

material.) [Derived from AEA, 10 CFR 20]

160. SOURCE TERM. The amount of a specific pollutant (e.g., chemical, radionuclide) emitted or

discharged to a particular environmental medium (e.g., air, water) from a source or group of sources.

It is usually expressed as a rate (i.e., amount per unit time). [Derived from TM, Suter]

161. SPECIAL NUCLEAR MATERIAL (SNM). A category of material subject to regulation under the

Atomic Energy Act, consisting primarily of fissile materials. It is defined to mean plutonium, uranium-
