Report # 18: November 6 - November 10, 2006

« Back to Atlas Tack Superfund Site Fact Sheet

1. ACTIVITIES PERFORMED DURING THE WEEK OF NOVEMBER 6 - NOVEMBER 10

  • Transportation & disposal (T&D) of SUB-D soils
  • Returned to Commercial and Industrial Debris Area (CID) and excavated along cells: G1, F2, E2, D2, C2, A4
  • Continued to excavate soils in the NW-Fill Area
  • Continued to screen soils originating from the NW-Fill Area
  • Finalized T&D package for the disposal of additional COMM-97 soils to be T&D to Marion (1,500-cy)

Ongoing Site Activities:

  • Collected waste characterization soil samples from soils originating from NW-Fill Area for off site landfill profiling and dispoal
  • Collected confirmatory soil samples from the floors of the NW-Fill Area and both sidewalls and floors from the CID
  • Continue water handling activities
  • Continued to inspect trucks prior to exiting the site
  • Continued to provide flaggers to cross trucks across the bike paths along Adams and Tripp Streets
  • Continued stockpile management activities
  • Continue with air monitoring program

2. PROJECTED ACTIVITIES FOR THE WEEK OF NOVEMBER 13 - NOVEMBER 17

  • T&D Oversize Debris (1,500-cy) to the Bourne Landfill and (1,500-cy) of COMM-97 soils to the Marion
  • Continue to T&D Subtitle-D soils to TREE (Turnkey, Rochester, NH)
  • Continue with excavation activities in the Northwest Fill Area
  • Collect waste characterization soil samples from soils originating from Northwest Fill Area
  • Collect confirmatory soil samples from the NW-Fill Area
  • Screen soils originating from the Northwest Fill Area

Ongoing Site Activities:

  • Continue to collect pre and post excavation survey data of the excavations
  • Continue with stockpile management activities
  • Continue water handling activities
  • Continued to inspect trucks prior to exiting the site
  • Continued to provide flaggers to cross trucks across the bike paths along Adams and Tripp Streets
  • Continue with air monitoring program

3. AIR MONITORING INFORMATION

WESTON monitored for particulate (dust) during intrusive activities performed during this reporting period. WESTON recognizes EPA's level of concern for "PM10" to caution sensitive groups, including children, the elderly, and people with heart or lung disease, about exposure to coarse dust particles. The PM10 level of concern for sensitive groups is 150 µg/m3 for 24-hour average exposure.

Perimeter Air Monitoring is performed at up to (6) locations throughout a given work day. Readings are collected at 60 second intervals throughout the day and reported as a daily average.

If exceedances are identified, an increased effort of engineering controls (water suppression) will be utilized to adhere to the PM10 level of concern. If engineering controls appear to be inadequate, any dust generating activities will stop. Current dust control practices will be re-evaluated until concentrations are reduced to below the PM10 standard.

Results for 2 November – 8 November 2006 can be reviewed in the table below.

Notes:
All readings reflect the daily average calculated over the course of the workday.
All readings collected with a Thermo Electron PDR 1000.
NSC: No sampling conducted; No intrusive work conducted in that area.
Precip: No sampling conducted due to precipitation.
*: Monitoring conducted over 24-hour period.
**: No work and air monitoring occurs on weekend days

If exceedances are identified, an increased effort of engineering controls (water suppression) will be utilized to adhere to the PM10 level of concern. If engineering controls appear to be inadequate, any dust generating activities will stop. Current dust control practices will be re-evaluated until concentrations are reduced to below the PM10 standard.
