40.0800:   Comprehensive Response Actions

310 CMR 40.0801 through 40.0899, cited collectively as 310 CMR 40.0800, contain the requirements and procedures for conducting Comprehensive Response Actions at disposal sites.

40.0801:   Applicability

The procedures, requirements, and standards set forth in 310 CMR 40.0800 apply to:

(a)   all disposal sites for which a Phase I Initial Site Investigation Report has been prepared in accordance with the provisions of 310 CMR 40.0480, and where additional response actions are necessary to assess the disposal site and/or evaluate and implement Comprehensive Remedial Actions to achieve a Response Action Outcome under 310 CMR 40.1000; and

(b)   all Locations To Be Investigated and disposal sites described in 310 CMR 40.0600 for which a Phase I investigation has been completed and where additional response actions are necessary to assess the disposal site and/or evaluate and implement Comprehensive Remedial Actions.

40.0810:   General Provisions for Comprehensive Response Actions

(1)   Comprehensive Response Actions shall be performed in sequential phases.  The phases of Comprehensive Response Actions  consist of:

(a)   Phase II -  Comprehensive Site Assessment;

(b)   Phase III - Identification and Selection of Comprehensive Remedial Action Alternatives;

(c)   Phase IV - Implementation of the Selected Remedial Action Alternative; and

(d)   Phase V - Operation, Maintenance and/or Monitoring

(2)   The results of each phase of Comprehensive Response Actions shall be documented in one or more reports, and submitted to the Department in a manner specified in 310 CMR 40.0800 and within the applicable deadlines specified in 310 CMR 40.0550 and 40.0560.  Where appropriate, Comprehensive Response Action reports may be combined and submitted to the Department simultaneously.

(3)   Each phase of Comprehensive Response Actions shall build upon the results of previous work, continuing until a Response Action Outcome as described in 310 CMR 40.1000 is reached for the disposal site.  The Department shall not recognize receipt of a Completion Statement for a Phase unless the Completion Statement for the previous Phase has been submitted.

(4)   RPs, PRPs and Other Persons conducting Comprehensive Response Actions at disposal sites shall comply with all applicable provisions of 310 CMR 40.0800 and this Contingency Plan.

(5)   RPs, PRPs and Other Persons conducting Comprehensive Response Actions shall engage or employ the services of a Licensed Site Professional.

(6)   The scope and level of detail of response actions taken under 310 CMR 40.0800 shall be commensurate with the nature and complexity of the specific disposal site.  The investigation process described in 310 CMR 40.0800 is intended to allow for varying levels of effort from disposal site to disposal site to avoid the collection of unnecessary information and unwarranted steps that could delay remedial actions.  In all cases, the scope and level of detail of response actions taken under 310 CMR 40.0800 shall be sufficient to ensure that the applicable requirements and performance standards of these regulations are met, and that the response actions are conducted in a manner consistent with the Response Action Performance Standard as described in 310 CMR 40.0191.

(7)   Technical justification, as described in 310 CMR 40.0193, may be provided to limit or forego one or more of the assessment or evaluation elements of 310 CMR 40.0800.  Technical justification may not be used to forgo procedural requirements, such as the submission of reports, notices or documents required as part of Comprehensive Response Actions under 310 CMR 40.0800.  When technical justification is used to forgo or limit an assessment or evaluation element, a description of the site-specific conditions and characteristics that make the requirement unwarranted and any documentation necessary to support any such justification shall be provided in the applicable submittal to the Department.

(8)   If at any time during the conduct of response actions under 310 CMR 40.0800 an Imminent Hazard, sudden release, or other time-critical release or site condition is identified at a disposal site, as described in 310 CMR 40.0412, Immediate Response Actions shall be performed as set forth in 310 CMR 40.0400.

(9)   Comprehensive Response Actions shall be conducted in a manner protective of health, safety, public welfare, and the environment, and in accordance with the Health and Safety provisions of 310 CMR 40.0018.

(10)   Nothing in 310 CMR 40.0800 shall limit the ability of the Department to initiate, oversee, or order the performance of any response action deemed necessary by the Department to protect health, safety, public welfare, or the environment or impose additional requirements which are consistent with the purposes on M.G.L. c. 21E or 310 CMR 40.0000.

(11)   Notwithstanding any provision to the contrary, the Department may at any time require an RP, PRP or Other Person undertaking Comprehensive Response Actions pursuant to 310 CMR 40.0800 to obtain prior Departmental approval of one or more of the response actions  or submittals required pursuant to 310 CMR 40.0800.  The Department may require such prior approval for submittals or response actions as they relate to the entire disposal site or to some portion thereof.

40.0859:   Selection of Remedial Action Alternative

(1)   Except as provided in 310 CMR 40.0857(2), remedial action alternatives shall be selected based on the detailed evaluation criteria contained in 310 CMR 40.0858 and in compliance with the provisions set forth in 310 CMR 40.0850, 40.0900 and 40.1000.

(2)   A remedial action alternative which is a Permanent Solution shall be selected if a feasible Permanent Solution has been identified and its implementation is found to be more cost-effective and timely than would be the implementation of a Temporary Solution.  If there is no such feasible Permanent Solution, a Temporary Solution for the elimination of substantial hazard shall be selected and implemented and a plan shall be prepared pursuant to 310 40.0861(2)(h) for the identification and development of a Permanent Solution.

(3)   Any selected Permanent Solution shall, to the extent feasible, reduce the concentrations of oil and hazardous material in the environment to levels that achieve or approach background.

40.0860:   Feasibility Evaluations

(1)   The criteria described in 310 CMR 40.0860 apply to:

(a)   evaluating the feasibility of implementing a Permanent Solution;

(b)   evaluating the feasibility of reducing the concentrations of oil and hazardous material in the environment to levels that achieve or approach background;

(c)   evaluating the feasibility of reducing the concentrations of oil and hazardous material in soil at a disposal site to levels at or below applicable soil Upper Concentrations Limits; and

(d)   evaluating the feasibility of eliminating, preventing or mitigating Critical Exposure Pathway(s).

(2)   An evaluation of the feasibility of implementing a Permanent Solution shall be performed in all cases where the selected Comprehensive Remedial Action alternative is a Temporary Solution.

(3)   An evaluation of the feasibility of reducing the concentrations of oil and hazardous material in the environment at the disposal site or a portion of the disposal site to levels that achieve or approach background shall be conducted in all cases where a Permanent Solution is selected as the Comprehensive Remedial Action alternative, unless the Permanent Solution selected is designed to achieve background and a Class A-1 Response Action Outcome pursuant to 310 CMR 40.1000.

(4)   An evaluation of the feasibility of reducing the concentrations of oil and hazardous material in soil at the disposal site to levels at or below the applicable soil Upper Concentration Limits shall be conducted before a Comprehensive Remedial Action alternative is selected as a Permanent Solution which would leave oil and/or hazardous material in soil at concentrations above the soil Upper Concentration Limits at a depth greater than 15 feet below the ground surface or beneath an engineered barrier, as that term is defined in 310 CMR 40.0996.

(5)   A remedial action alternative that would achieve a Permanent Solution,  would reduce the concentrations of oil and hazardous material in the environment at the disposal site or a portion of the disposal site to levels that achieve or approach background, or reduce concentrations of oil and  hazardous material in soil at a disposal site to levels at or below applicable soil Upper Concentration Limits shall be considered feasible unless:

(a)   the alternative is not technologically feasible, as specified in 310 CMR 40.0860(6);

(b)   the costs of conducting, or the risks resulting from the alternative would not be justified by the benefits, considering such factors as potential damage to human health or the environment, cost of environmental restoration, long term operation and maintenance costs, and non-pecuniary values as determined by the benefit-cost analysis in 310 CMR 40.0860(7);

(c)   individuals with the expertise needed to effectively implement the alternative would not be available, regardless of arrangements for securing their services; 

(d)   the alternative would necessitate land disposal other than at the site itself and no off-site facility is available in the Commonwealth or in other states that is in full compliance with all applicable federal and state regulatory requirements; or

(e)   an alternative is selected for a portion of a disposal site for which the source of the oil and/or hazardous material is not located thereon, and the elimination or control of such source cannot currently be achieved by the party conducting the response actions at that portion of the disposal site.  In such instances, a Temporary Solution shall be implemented for that portion of the disposal site to which the selected alternative applies.

(6)   Technological Feasibility.  A remedial action alternative shall be considered technologically feasible unless:

(a)   existing technology or reasonable modifications of existing technology cannot remediate the oil and hazardous material present at the disposal site to the extent necessary to attain a level of No Significant Risk or, when required to be considered, to levels that approach or achieve background;

(b)   the reliability of the identified alternative has not been sufficiently proven at other sites or through pilot tests and a substantial uncertainty exists as to whether it will effectively reduce risk; or

(c)   the identified alternative cannot comply with or be modified to comply with applicable regulatory requirements.

(7)   Benefit-Cost Analysis.  The benefits of implementing a remedial action alternative to achieve a Permanent Solution or Temporary Solution and the benefits, when performing a Permanent Solution, of reducing the concentrations of oil and hazardous material in the environment at the disposal site to levels which achieve or approach background  or reducing the concentrations of oil and hazardous material in soil at a disposal site to levels at or below applicable soil Upper Concentration Limits shall justify the related costs unless:

(a)   the incremental cost of conducting the remedial action alternative is substantial and disproportionate to the incremental benefit of risk reduction, environmental restoration, and monetary and non-pecuniary values;

(b)   the risk of harm to health, safety, public welfare or the environment posed by the implementation of the alternative cannot be adequately controlled; or

(c)   the alternative would destroy more than 5000 square feet of wetlands or wildlife habitat, or would otherwise result in a substantial deleterious impact to the environment and:

1.   other feasible Temporary or Permanent  Solutions exist;

2.   the oil and/or hazardous materials, if any, that have come to be located in such resources do not bio-accumulate and are not likely to migrate; and

3.   the damage to such resources resulting from the implementation of the alternative would be permanent and irreparable.

40.0861:   Remedial Action Plan

(1)   The results of a Phase III evaluation shall be documented in a Remedial Action Plan.  The Remedial Action Plan shall support the selection of a remedial action alternative by providing information of sufficient detail on the process by which the recommended remedial action alternative was developed and evaluated.

(2)   A Remedial Action Plan shall contain:

(a)   a description of all remedial action alternatives initially identified and the results of the initial screening;

(b)   where a detailed evaluation is required, a discussion of how the alternatives remaining after initial screening compared with respect to each of the detailed criteria described in 310 CMR 40.0858, and how the criteria were weighted in the evaluation;
