This revised Monitoring and Maintenance Implementation Plan (MMIP) has been prepared by Woodard & Curran on behalf of the University of Massachusetts (UMass) to update the existing MMIP incorporated into the Consent Agreement and Final Order (CAFO) dated June 21, 2012, between UMass and the U.S. Environmental Protection Agency (EPA) for the Lederle Graduate Research Center (LGRC) Tower A and Low Rise buildings located at 701- 740 North Pleasant Street on the UMass campus in Amherst, Massachusetts. Given that conditions have changed since preparation and submittal of the CAFO MMIP, specifically the decision to remove windows from the Low Rise Building, this revised MMIP has been prepared to reflect current conditions.
This plan presents the monitoring and maintenance activities that will be conducted to assess the long-term effectiveness of the encapsulants applied, as an interim measure, to interior glazing sealants identified as containing polychlorinated biphenyls (PCBs) at concentrations ≥ 50 parts per million (ppm).
