Best Demonstrated Avaialable Technology (BDAT)

DOE-HDBK-1188-2006

Under the Safe Drinking Water Act:

The best technology, treatment techniques, or other means that the Environmental Protection Agency

Administrator finds, after examination for efficacy under field conditions and not solely under

laboratory conditions, are available taking cost into consideration. For the purposes of setting

maximum contaminant levels (MCLs) for synthetic organic chemicals, any BAT must be at least as

effective as granular activated carbon. (See maximum contaminant level.) [40 CFR 141.2, EPA

Glossary, WQA Glossary]

20.

BEST DEMONSTRATED AVAILABLE TECHNOLOGY (BDAT). The most effective

commercially available means of treating specific types of hazardous waste, as designated by the

Environmental Protection Agency in 40 CFR Part 268. BDATs may change with advances in

treatment technologies. [Derived from EPA Terms]

21.

BEST MANAGEMENT PRACTICES (BMP). Structural, nonstructural, and managerial techniques,

other than effluent limitations, to prevent or reduce pollution of surface water. They are the most

effective and practical means to control pollutants that are compatible with the productive use of the

resource to which they are applied. BMPs are used in both urban and agricultural areas. BMPs can

include schedules of activities; prohibitions of practices; maintenance procedures; treatment

requirements; operating procedures; and practices to control plant site runoff, spillage or leaks, sludge

or waste disposal, or drainage from raw material storage. [Derived from EPA Glossary, 40 CFR

122.2, 40 CFR 232.2]

22.

BETA RADIATION. Ionizing radiation consisting of fast moving, positively or negatively charged

elementary particles emitted from atomic nuclei during radioactive decay. Beta radiation is more

penetrating, but less ionizing than alpha radiation. Negatively charged beta particles are identical to

electrons; positively charged beta particles are known as positrons. Both are stopped by clothing or a

thin sheet of metal. [Derived from EPA RPD]

23.

BOUND. To use simplifying assumptions and analytical methods in an analysis of impacts or risks

such that the result overestimates or describes an upper limit on (i.e., Abounds@) potential impacts or

risks.

Related terms:

A bounding analysis is an analysis designed to overestimate or determine an upper limit to potential

impacts or risks.

A bounding accident is a hypothetical accident, the calculated consequences of which equal or

exceed the consequences of all other potential accidents for a particular activity or facility.
