Weekly Activities

January 11, 2016: The flushing of the sheet pile joints has been completed. The area around the barrier wall alignment has been backfilled and stabilized. Soil borings to find the optimal locations for the recovery wells that will be installed at a later date were advanced.

CAMP data is reviewed and compared to specific NYSDEC/NYSDOH approved criteria, known as “Action Limits.” As a result of this evaluation process, site conditions are categorized into two categories, “Operational Condition” and “Action Condition.” The “Operational Condition” is applicable when the data is below the “Alert, Response and Action Limits”, and means that normal operations can continue. The “Action Condition” occurs when one or more of the fifteen minute average measurements for Dust (PM₁₀), Total Volatile Organic Compounds (TVOC) or Odor Intensity are greater than the background or upwind measurement by the specified “Action Limits.” Reaching an Action Level requires corrective action or stopping work until the condition is addressed or abates. During the period from Monday, January 11, 2016 through Friday, January 15, 2016, four portable CAMP stations were in-use and measured TVOC and PM₁₀. Fifteen-minute averages for TVOC data remained below the Action Limit. However, there were 15-minute average PM₁₀ concentrations greater than the Action Limit on Wednesday, January 13, 2016 at two of the four portable stations. The elevated PM₁₀ concentrations were caused by gusty winds blowing dust across the site.

For the week of January 18, 2016, the soil borings associated with the recovery wells will be completed and remaining equipment will be demobilized from the bulkhead area. Work in the bulkhead area will be shut down while the soil boring observations are reviewed and the recovery well locations are determined. Continuation of work will also be based on when DOT completes its evaluation of Beach Channel Drive and deems that it is safe to continue.
