Air monitoring will be performed during the earthwork activities as described in GZA’s February 20, 2012 Evaluation of Applicability of Air Pollution Control Regulation No. 9 submittal to the RIDEM Office of Air Resources and GZA’s subsequent correspondence with RIDEM dated June 14, 2012 and July 27, 2012.  On July 5, 2012, RIDEM issued a letter stating that an air permit for these proposed earthwork activities would not be required. A summary memorandum of the air quality monitoring program which will be implemented during earthwork activities associated with the upcoming electrical substation upgrade project was submitted to RIDEM on September 28, 2012. Once the earthwork activities begin at the Site associated with the electrical substation upgrades, status report updates will be provided on a weekly basis. Replacement of the meter building associated with natural gas regulator station is currently planned for the end of November 2012. This work consists of aboveground work and will not involve soil excavation. Equipment associated with the building replacement work, including a crane, may be mobilized to the Site during the reporting period.
