Section 30.616 - Special Requirements for Ignitable, Reactive, incompatible, and Acutely Hazardous Wastes, and Hazardous Wastes that are Polyhalogenated Aromatic Hydrocarbons(1) Ignitable or reactive waste shall not be placed in a surface impoundment unless the waste and impoundment satisfy all applicable requirements of 310 CMR 30.750 and: (a) The waste is treated before or immediately after placement in the impoundment so that: 1. The resulting material is no longer ignitable or reactive hazardous waste pursuant to 310 CMR 30.122 or 30.124; and2.310 CMR 30.560(3) is complied with; or(b) The surface impoundment is used solely for emergencies.(2) Ignitable or reactive hazardous wastes which are incidental to the storage or treatment of non-ignitable or non-reactive hazardous wastes in the impoundment shall be concentrated, collected, and removed from the impoundment. Where such ignitable or reactive hazardous wastes are present in the impoundment, such wastes shall be managed so that they are protected from any material or condition which may cause them to ignite or react.(3) Incompatible hazardous wastes, or materials incompatible with hazardous wastes (see310 CMR 30.561 for examples) shall not be placed in the same surface impoundment unless 310 CMR 30.560(3) is complied with.(4) Acutely hazardous waste identified in 310 CMR 30.136 shall not be placed in a surface impoundment.(5) Polyhalogenated aromatic hydrocarbons shall not be placed in a surface impoundment except in accordance with all other applicable provisions of 310 CMR 30.610 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 surface impoundment 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 surface impoundment, 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 surface impoundment.(d) The effectiveness of additional treatment, design, or monitoring techniques used by the owner or operator of the surface impoundment. 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.
