The Massachusetts Contingency Plan, (MCP), (310 CMR 40.000) is a body of regulations administered by the Massachusetts Department of Environmental Protection (DEP) designed to streamline and accelerate the assessment and cleanup of hazardous materials releases to the environment. Wellesley College has been working with DEP and other agencies to address contamination at the former paint pigment factory site in accordance with the MCP. The MCP outlines cleanup planning and reporting in five phases. They are listed below.

Phase I - Initial Evaluation of Site Conditions and Interim Remediation
In Phase I, an initial evaluation was conducted of potential soil and water contamination on the former paint pigment factory site. The evaluation was conducted to provide baseline information to define the area affected by past paint pigment waste deposit practices, and to assess the need for short-term remedial measures while the evaluation of the site proceeded. Please click below to review results of the evaluation and a list of interim remediation measures that were taken by the College.

Phase II - Comprehensive Site Assessment (CSA)
The purpose of the Phase II investigation was to characterize the type and extent of paint pigment residuals, and estimate their impact on soil and groundwater quality. The work performed included subsurface investigations and soil borings/multi-level groundwater monitoring wells, and environmental and waste sample collection including groundwater, soils, waste pigments, and air.

Phase III - Identification, Evaluation and Selection of Comprehensive Remedial Action Alternatives
The Remedial Action Plan (RAP) presented nine cleanup alternatives, including the "no action" alternative, for remediation of upland soil, wetland sediment, and Paintshop Pond sediment. The RAP summarized the existing environmental conditions at the project site and described all of the remedial alternatives and criteria used to evaluate them. Please click below to review a description of each alternative, a comparison of the nine alternatives, and a detailed rationale for the College¹s preferred alternative.

• RAP ­ December 13, 1999
  
  

Phase IV - Implementation of the Selected Remedial Action Alternative
Construction or operation of the remedial action alternative cannot start until the Remedial Implementation Plan (RIP) has been approved by DEP. Phase IV contains requirements for the design, construction and implementation of the cleanup, including documentation that all workers will have appropriate training and supervision, and that all federal, state and local permits and approvals have been secured.

Phase V - Operation, Maintenance, and/or Monitoring
At the end of cleanup, Phase V requires that the site be maintained and/or monitored at regular intervals until the Response Action Outcome has been achieved.
