as an impurity.
Mixture means any combination of two or more chemicals, if the combination is not, in whole
or in part, the result of a chemical reaction. However, if the combination was produced by a
chemical reaction but could have been produced without a chemical reaction, it is also treated
as a mixture. A mixture also includes any combination which consists of a chemical and
associated impurities.

equipment which is ancillary to the reaction vessel or similar equipment, and any equipment
through which the intermediate passes during a continuous flow process, but not including tanks
or other vessels or equipment in which the substance or product is stored after manufacture.
Office means Office of Technical Assistance and Technology within the Executive Office of

repackaging of the toxic substance occurs does not constitute use or processing of the toxic
substance.

at the most economical cost under the estimated life of the works, including intercepting sewers,
outfall sewers, sewage collection systems, pumping, power, and other equipment, and the
appurtenances; extensions, improvements, remodeling, additions, and alterations thereof;
elements essential to provide a reliable recycled supply such as standby treatment units and clear
