Transportation Related Area means a parking area or other place where shipments of hazardous waste are held by a transporter during the normal course of transportation. A transportation related area shall not include a hazardous waste transfer station, school or hospital parking lot, or residentially zoned location.

Treatability Study means a study in which a hazardous waste is subjected to a treatment process to determine

(a) whether the waste is amenable to the treatment process;
(b) what pretreatment, if any, is required;
(c) the optimal process conditions needed to achieve the desired treatment;
(d) the efficiency of a treatment process for a specific waste or wastes; or
(e) the characteristics and volumes of residuals from a particular treatment process. For the purpose of implementing 310 CMR 30.104(3)(b) and 30.104(3)(c) exemptions, 310 CMR 30.010: Treatability Study also includes liner compatibility, corrosion, and other material compatibility studies and toxicological and health effects studies. Treatability Study shall not include, and a Treatability Study is not, a means to commercially treat or dispose of hazardous waste.

Treatment means any method, technique or process, including neutralization, incineration, stabilization or solidification, designed to change the physical, chemical or biological character or composition of any hazardous waste so as to neutralize such waste or so as to render such waste less hazardous, nonhazardous, safer to transport, amenable to storage, or reduced in volume, except such method or technique as may be included as an integral part of a manufacturing process at the point of generation.

Treatment Which is an Integral Part of the Manufacturing Process means any treatment method or technique which is at the site of generation of the waste, is not primarily for the purpose of recycling hazardous waste, and is:

(a) Directly connected via pipes or the equivalent from an industrial production process [i.e., a process which produces a product, produces an intermediate, produces a by-product, renders a service (e.g., dry-cleaning), or produces a material which is used back in the production process]; and
(b) Totally enclosed so that it is designed, constructed, and operated to prevent spills, leaks, or emissions of hazardous materials to the environment. A treatment unit may be deemed "totally enclosed" if it is completely contained on all sides (i.e., an open-topped tank or treatment vessel shall not be deemed totally enclosed). If a treatment unit is vented, it may be deemed "totally enclosed" only if such vent(s) is/are designed to prevent overflow and emissions of gases, vapors, or aerosols where such events might occur through normal operation, equipment failure, or process upsets. This shall be accomplished through the use of suitable traps, recycle lines, sorption units, or the equivalent. If the effluent from the treatment unit discharges to surface water, ground water, or a sewer, the treatment unit may be deemed "totally enclosed" only if all discharges are in compliance with all applicable Federal, State, and local laws, regulations, and permits. If one unit operation in a series of unit operations is not "totally enclosed" or connected by pipe to the unit immediately upstream from that unit, then only unit operations upstream from that unit may be deemed "treatment which is an integral part of the manufacturing process".

Treatment Zone means a soil area of the unsaturated zone of a land treatment unit within which hazardous constituents are degraded, transformed, or immobilized.

If an eligible academic entity elects to use another equally effective term in lieu of "unwanted material," as allowed by 310 CMR 30.354(6)(a)1.a., the equally effective term has the same meaning and is subject to the same requirements as "unwanted material" under 310 CMR 30.354.
