Phase III Remedial Action Plan (RAP)

The Phase II Comprehensive Site Assessment (CSA) was completed and approved by the Massachusetts Department of Environmental Protection (MassDEP) on August 16, 2006. This Revised Phase III Identification, Evaluation and Selection of Comprehensive Remedial Action Alternatives (Phase III, 310 Code of Massachusetts Regulations (CMR) 40.0850) (hereafter referred to as the Remedial Action Plan (RAP)) is being performed in accordance with the Massachusetts Contingency Plan (MCP) to develop and evaluate comprehensive remedial action alternatives for the Fireworks Site (the Site). An initial Phase III RAP was submitted to the MassDEP on November 12, 2007 and was presented to the Site stakeholders at a public meeting held at the Hanover Town Hall on February 27, 2007 (TtEC, 2007). This Revised Phase III RAP incorporates new sampling and field investigation results collected in the Fall of 2008 and in February of 2009. These Phase III supplemental sampling activities were described and reported in the Phase III Supplemental Data Report (TtEC, 2009). The Phase III evaluation activities for the Site included the following:

  • Development of Site-wide and area-specific remedial objectives (ROs);
  • Development of Site-wide risk-based preliminary remediation goals (PRGs) designed to eliminate or reduce the significant potential human health and environmental risks identified during the CSA;
  • Development of remedial action alternatives for the clean-up of the contaminated media at the Site (i.e., sediment, soil, and groundwater);
  • Selection of a recommended remedial alternative for the Site; and
  • Preparation of the RAP.
