GZA will continue to oversee soil management and conduct air monitoring during these earth disturbing activities. Air monitoring will be performed consistent with the summary memorandum which was submitted to RIDEM on September 28, 2012. The remainder of the work associated with the electrical substation upgrade project will consist of aboveground work within the substation and buildings.  It is currently anticipated that the aboveground work associated with the substation upgrades will continue until the end of 2013.

Earthwork associated with the proposed electrical substation upgrades is currently anticipated to begin in September 2012. An evaluation regarding the applicability of Air Pollution Control Regulation No. 9 with respect to the excavation work associated with proposed electrical substation upgrades was submitted to RIDEM on February 13, 2012.

• Complete site observation walk.
• Complete annual groundwater and NAPL monitoring round.

The excavation work associated with the regulator station upgrades is complete. Above-ground work associated with the regulator station is complete, except for replacement of one of the buildings within the regulator station fence line. The schedule for this work is currently being evaluated. Earthwork associated with the proposed electrical substation upgrades is currently anticipated to begin in August 2012. An evaluation regarding the applicability of Air Pollution Control Regulation No. 9 with respect to the excavation work associated with proposed electrical substation upgrades was submitted to RIDEM on February 13, 2012.

• Complete site observation walk.
• Complete limited emergency earthwork associated with repair of water line located immediately south of the natural gas regulator station. During earthwork activities, air monitoring will be performed by GZA consistent with the RIDEM approved, April 2011 Air Quality Monitoring Program (AQMP) and subsequent May 5, 2011 correspondence.  We currently anticipate this limited repair will be completed in one to two days and will involve a minimal amount of soil disturbance (approximately 10 cubic yards). It is anticipated that excavated material will be reused as backfill and no soil will be transported off-site.

• Complete site observation walk.
• Continue the assessment of the conditions of the remaining three buildings located on the Former Manufactured Gas Plant Area (FGPA) portion of the Site.  This assessment will be used by The Narragansett Electric Company as part of an evaluation to raze these historic structures. This work is tentatively scheduled to be performed on June 1, 2012.
