Weekly Update – Week Ending June 26, 2009

Remedial Investigation

Remedial Investigation field work resumed in late May at the former Fulton Municipal Works MGP as part of the New York State Department of Environmental Conservation (NYSDEC) and New York State Department of Health (NYSDOH)-approved Remedial Investigation Work Plan (RIWP).  The work includes the installation of soil borings, monitoring wells, test pit excavations, and soil vapor points to gather information required to determine the nature and extent of impacts within the footprint of and adjacent to the former Fulton Municipal Works MGP.  National Grid continued to pursue access to complete the remaining proposed RI activities.

Based upon the preliminary findings of the RI completed to date, National Grid and NYSDEC have agreed that additional delineation of deeper soil impacts will be needed at off-site areas in the vicinity of the MGP.  National Grid is currently preparing a work plan to address this request.

Activities May 27 through June 26:

  • Utility survey and clearance were completed.
  • Soil borings and monitoring wells were installed.
  • Test pit excavations were completed.
  • Soil vapor points were installed.
  • Groundwater was gauged in monitoring wells and groundwater samples were collected from select monitoring wells.

Future (two week look-ahead) activities:

  • Continue the installation of monitoring wells.
  • Collect soil vapor and ambient air samples.
  • Submit the RI work plan addendum to complete off site investigations.
