Section 30.657 - Special Requirements for Ignitable, Reactive, incompatible, and Acutely Hazardous Wastes, and Hazardous Wastes that are Polyhalogenated Aromatic Hydrocarbons(1) The owner or operator shall not apply ignitable or reactive waste to the treatment zone unless the waste and the treatment zone meet all applicable requirements of 310 CMR 30.750 and the waste is immediately incorporated into the soil so that: (a) The resulting material is no longer ignitable or reactive hazardous waste pursuant to 310 CMR 30.122 or 30.124; and(b)310 CMR 30.560(3) is complied with.(2) Incompatible hazardous wastes, or materials incompatible with hazardous wastes (see310 CMR 30.561 for examples) shall not be placed in or on the same treatment zone unless 310 CMR 30.560(3) is complied with.(3) Acutely hazardous waste identified in 310 CMR 30.136 shall not be treated or disposed of at a land treatment facility.(4) Polyhalogenated aromatic hydrocarbons shall not be placed in a land treatment facility except in accordance with all other applicable provisions of 310 CMR 30.650 and in accordance with the terms and conditions of a management plan, approved by the Department, for such placement. Compliance with such a plan, when approved, shall be a condition of a license issued pursuant to 310 CMR 30.000. The Department may approve a management plan for the placement of polyhalogenated aromatic hydrocarbons in a land treatment facility only if, after considering at least the following criteria, the Department determines that such approval is in accordance with provisions set forth in 310 CMR 30.810 through 30.814. (a) The volume and physical and chemical characteristics of the polyhalogenated aromatic hydrocarbons, including their potential to migrate through the soil or to volatilize or escape into the atmosphere.(b) The volume and physical and chemical characteristics of the other materials placed into the land treatment facility, including their potential to migrate through the soil or to volatilize or escape into the atmosphere.(c) The attenuative properties of the soil and other materials surrounding or underlying the land treatment facility.(d) The effectiveness of additional treatment, design, or monitoring techniques used by the owner or operator of the land treatment facility. The Department may require the use of additional or different treatment, design, or monitoring techniques to reduce the possibility of migration or emission of these materials into ground water, surface water, soil, or air.
