Disposition cont'd

DOE-HDBK-1139/1-2006

the facility inventory in an expeditious manner that is documented and in

compliance with all applicable regulations. For example, disposition of unneeded

chemicals is handled through property management regulations. The final

disposition of the chemicals should be recorded, and all applicable records should

be transferred to the appropriate personnel.

Identifying a "waste"

A determination should be made as to whether a site's chemicals (materials) meet

the regulatory definition of a "waste."

A waste is any material that is discarded by being abandoned (i.e., disposed

of, burned, or incinerated), recycled, or considered inherently waste-like .

Certain materials that are "accumulated speculatively" are designated as

40 CFR 261.2

waste .

It is important to recognize that certain materials in inventory (MIN) may

meet the regulatory definition of a waste, and thus be subject to waste

management requirements. If MIN chemicals are not reused or exchanged,

they fall into the waste category and should be dispositioned [per the DOE

Office of Environmental Management's (EM) MIN Initiative].

Identifying a "hazardous waste"

The generator of a waste is responsible for determining whether waste is a

"hazardous waste" subject to regulatory requirements.

Procedures should ensure that a timely determination is made (by a

qualified person).

Procedures should be based on definitions in RCRA and applicable state

law.

To be classified as "hazardous," a chemical waste must exhibit one or more

characteristics of hazardous waste, or be listed as a hazardous waste.

Hazardous Waste

Note that the listed hazardous wastes include pure and commercial grade

40 CFR 261.20,

formulations of certain unused chemicals [i.e., Pure (P) and Unused (U)

261.21, 261.22,

listed wastes].
