Waste Site Cleanup & Reuse in New England

Atlas Tack Corporation Superfund Site
Bi-Weekly Remedial Activities Update
Report # 25: January 29 – February 9, 2007

« Back to Atlas Tack Superfund Site Fact Sheet

I. ACTIVITIES PERFORMED DURING THE WEEKS ENDING: 2 FEB & 9 FEB

Site Preparation
  • Completed installation of box culvert dam south of hurricane dike
  • Completed installation of check dam crossing
  • Completed construction of transfer station and solidification bins (addition of saw dust)
  • Extended transfer station to the west, reinforcing the portion of the salt marsh used as the approach to the solidification bins
Haul Road Construction
  • Identified that the marsh was unstable to sustain repeated traction over the marsh
  • Installed 800-ft of haul road to prevent damage to the marsh surface located east of the creek
  • Haul road construction consisted of a layer of non-woven geotextile placed over the salt marsh surface and covered with a 1-2-ft layer of rip rap
Excavation
  • Commenced excavation south of the hurricane barrier
  • Excavated a horizontal 1-ft cut along the east and west bank of Boy’s Creek
  • In an attempt to taking advantage of the solid 0.5-1-ft layer of frost out on the marsh, began to excavate salt marsh areas west of the creek, working north to south
  • In addition to the (2) crawlers (light weight dump trucks), the off-road dump was mobilized south of the barrier
  • In concurrence with the roll-off containers, the off-road dump truck will transport soil from south of the barrier to the soil staging area via access across the marsh north of the barrier, avoiding crossing the bike path and the use of Egypt Lane to the north of the path
Soils Management
  • Solidified all saturated soil excavated south of the hurricane barrier using saw dust
  • Continued to consolidate, stockpile, cover and secure stockpiles located in the stockpile staging area
Transportation & Disposal
  • 1,500 cy COMM-97 soil transported to the un-lined disposal facility located in Marion, MA
  • Began transport of additional 1,500 cy like soil to the Marion landfill
Stabilization
  • Applied Enviroblend 20/80 (also known as tri-sodium phosphate) coarse at a 1% blend for the treatment of TCLP (lead); stabilized 1000 cy soil
  • Applied a combination of Enviroblend 20/80 coarse at a 1% blend and Enviroblend 90/10 coarse at a 6% blend, to treat 250 cy soil for lead and cadmium
  • Received delivery of (22) 1-ton sacks of Enviroblend 90/10 coarse to be used to stabilize 2,250 cy soil for cadmium
De-Watering
  • Closed the drop gate at the hurricane barrier and installed a dedicated 4-inch dry prime diesel pump north of the hurricane barrier and began to redirect the water over the barrier to the discharge location located south of the box culvert dam
  • Installed the dedicated 4-inch dry prime diesel pump north of the box culvert dam to control the upstream flow of water, also discharging water south of the box culvert dam
  • Due to below freezing site conditions, the dedicated 4-inch dry prime located north of the barrier has failed repeatedly due to freezing suction and discharge lines; to avoid pumping over the barrier, the pump has since been relocated north of the check dam and the hurricane barrier drop gate opened to control the flow of upstream waters
  • When creek bed excavation activities are re-visited, the pump will then be placed back north of the hurricane barrier and the drop gate closed
Sampling
  • Received waste characterization results of the stockpile containing the soils tainted with fuels originating from the existing underground fuel storage tank (UST)
  • Collected a grab sample of the soil tainted with the fuels from the UST for petroleum hydrocarbon analysis, results to be provided by 2/14/07
  • Collected post metal treatment confirmatory soil samples from treated stockpiles
  • Collected confirmatory soil samples from the marsh soil excavation south of the hurricane barrier
  • Collected additional marsh samples to further identify excavation limits
  • Provided additional air monitoring stations downwind of the stabilization effort and at the end of Egypt Lane.
Survey
  • Surveyed excavation limits located south of the hurricane barrier
  • Performed topographic survey of all proposed excavation locations south of the hurricane barrier
Miscellaneous
  • Removed a section of perimeter fence along the northeast corner of the site to provide access for the off-road dump to transport soil excavated south of the hurricane barrier, across the marsh north of the hurricane barrier, to the stockpile staging area
  • Removed vegetation in the area mentioned above
  • Fabricated and installed side rails for the (2) crawler dumps to prevent spillage
  • Continued to monitor both Adams St. and Tripp St entrances, inspecting the tractor trailers and removing clinging soils, crossing the trucks over the bike path and monitoring Tripp St. and Egypt Lane for any sign of migrating soil
  • Installed culvert in Boy’s Creek, north of the hurricane barrier to provide crossing for the off-road dump over the creek to the east fill area

II. POJECTED ACTIVITES FOR THE WEEKS ENDING: 16 FEB & 23 FEB

Excavation
  • Continue excavation of the salt marsh and creek bed south of the hurricane barrier
Soils Management
  • Continue to solidify all saturated soil with saw dust that was excavated south of the hurricane barrier
  • Continue to consolidate, stockpile, cover and secure stockpiles located in the stockpile staging area
Transportation & Disposal
  • Continue to transport COMM-97 soil represented to the Marion facility
  • Begin T&D of stabilized soil
Stabilization
  • Stabilize the remaining TCLP-failed lead and/or cadmium soil stockpiles
De-Watering
  • Continue to re-direct normal flow of water in Boy’s Creek and dewater excavation activities
Sampling
  • Continue to collect confirmatory soil samples from excavated areas
  • Continue to collect waste characterization samples of soil stockpiles
  • Continue to collect air monitoring data
Survey
  • Continue to provide post survey of excavated areas

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 25 January thru 7 February 2007 can be reviewed in the table below.
