Permissible Values

Value	Title	Description	Concentration Limits	Deep Disposal	Disposal Method	Institutional Control	Intruder Barriers	Nrc Evaluation	Segregation Requirements	Shallow Burial	Typical Sources	Waste Form Requirements
CLASS_A	Class A Low-Level Waste	Lowest radioactivity waste suitable for shallow land burial	lowest of three classes		shallow land burial				minimal		medical, industrial, power plants	none
CLASS_B	Class B Low-Level Waste	Intermediate radioactivity requiring waste form stability	intermediate		shallow land burial	100 years minimum			from Class A			structural stability
CLASS_C	Class C Low-Level Waste	Highest concentration suitable for shallow land burial	highest for shallow burial		shallow land burial	100 years minimum	required		enhanced			structural stability
GREATER_THAN_CLASS_C	Greater Than Class C Waste (GTCC)	Waste exceeding Class C limits, generally unsuitable for shallow burial	exceeds Class C	may be required	case-by-case evaluation			required		generally not acceptable
