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-233, uranium enriched in the isotopes uranium-233 or -235, and any other

material that the Nuclear Regulatory Commission determines to be special nuclear material,

but it does not include source material. [Derived from AEA, DOE 5610.12, 10 CFR 20, NRC
