Phase III Remedial Action Plan (310 CMR 40.0861)

Phase III Remedial Action Plan (310 CMR 40.0861)

The Phase III Report describes and documents the information, reasoning and results used to identify and evaluate remedial action alternatives in sufficient detail to support the selection of the proposed remedial action alternative. A Remedial Action Plan contains:

  • a description of all remedial action alternatives initially identified and the results of the initial screening;
  • where a detailed evaluation is required, a discussion of how the alternatives remaining after initial screening compared and how the criteria were weighted in the evaluation;
  • justification for the selection of the proposed remedial action alternative;
  • where required, the results of the evaluation of whether the implementation of a Permanent or Temporary Solution is feasible;
  • if a Permanent Solution is selected as the remedial action alternative:
    • a discussion of how the alternative is likely to achieve a level of No Significant Risk;
    • the results of the evaluation of the feasibility of reducing the concentrations of oil and hazardous material in the environment at the disposal site to levels that achieve or approach background, unless the Remedial Action Plan otherwise includes a demonstration that the selected alternative is designed to achieve background and a Class A-1 Response Action Outcome;
  • if a Temporary Solution is selected as the remedial action alternative:
    • a discussion of how the alternative is likely to eliminate any substantial hazards posed by the disposal site until a Permanent Solution is implemented;
    • a detailed description of definitive and enterprising steps to identify and develop an alternative that is a likely Permanent Solution and a schedule for the implementation of such steps including:
    • performing pilot tests or bench-scale studies;
    • investigating innovative ways to reduce the costs or the risks of implementing a specific alternative;
    • developing new technologies; and
  • a projected schedule for implementation of Phase IV activities.
