Initial Work Group Meeting


MassDEP Northeast Regional Office in Wilmington, Massachusetts.

During this meeting Work Group participants were introduced to the project and briefed on project details including the site selection process, plan for site surveys, development of tactics for each site, and final development and approval of all GRPs. 

Site Selection Meeting


EPA New England Regional Laboratory in Chelmsford, MA

During this meeting, participants reviewed all site sensitivity data compiled from Work Group members as well as the EPA, MassDEP, and Nuka Research, and determined the five sites to become GRPs for the Merrimack and Charles River respectively (10 sites total). 

Tactics Sub-Group Meeting


EPA New England Regional Laboratory in North Chelmsford, MA.

The Tactics Sub-Group was comprised of select individuals from the project Work Group with response expertise and/or in-depth knowledge of both river systems.  This Sub-Group  reviewed draft GRP maps that incorporated those tactics and strategies recommended by survey team members during the site surveys.  Changes to these initial tactics and strategies were made and the GRPs were updated prior to review by the Work Group at the final Work Group meeting.  

Final Work Group Meeting


EPA New England Regional Laboratory in Chelmsford, MA

This was the third and final meeting of the entire EPA GRP Work Group.  The purpose of this meeting will be to review the 10 draft GRPs developed since the Site Selection Meeting.  At this meeting, the draft GRPs were presented individually and participants reviewed and commented on GRP content.
