Sec.  61.31  Definitions.



    Terms used in this subpart are defined in the act, in subpart A of 

this part, or in this section as follows:

    (a) Beryllium means the element beryllium. Where weights or 

concentrations are specified, such weights or concentrations apply to 

beryllium only, excluding the weight or concentration of any associated 

elements.

    (b) Extraction plant means a facility chemically processing 

beryllium ore to beryllium metal, alloy, or oxide, or performing any of 

the intermediate steps in these processes.

    (c) Beryllium ore means any naturally occurring material mined or 

gathered for its beryllium content.

    (d) Machine shop means a facility performing cutting, grinding, 

turning, honing, milling, deburring, lapping, electrochemical machining, 

etching, or other similar operations.

    (e) Ceramic plant means a manufacturing plant producing ceramic 

items.

    (f) Foundry means a facility engaged in the melting or casting of 

beryllium metal or alloy.

    (g) Beryllium-containing waste means material contaminated with 

beryllium and/or beryllium compounds used or generated during any 

process or operation performed by a source subject to this subpart.

    (h) Incinerator means any furnace used in the process of burning 

waste for the primary purpose of reducing the volume of the waste by 

removing combustible matter.

    (i) Propellant means a fuel and oxidizer physically or chemically 

combined which undergoes combustion to provide rocket propulsion.

    (j) Beryllium alloy means any metal to which beryllium has been 

added in order to increase its beryllium content and which contains more 

than 0.1 percent beryllium by weight.

    (k) Propellant plant means any facility engaged in the mixing, 

casting, or machining of propellant.
