CIC Summary
July 7, 1999
Next Meeting
Aug 24, 1999
Winston-Thomas
Work is 95% done
Tertiary Lagoon Sludge Excavation Completee
Tertiary Lagoon Filter Cake Sent to EQ Landfill in Michigan - 25, 881 tons
Tertiary Lagoon TSCA Soils Sent to EQ Landfill - 15, 383 tons (20,000 total)
Tertiary Lagoon Non-TSCA soils sent Southside Landfill in Indianapolis
- Air Monitoring - 0 days greater thatn Action Level of 1mg/m3
- Total Gallons of Waste Treated 47,943,380
- Total Gallons Pumped to Sewer 2,142,00
- EPA and City split sampling Consistent with CBS results
- South Berm Excavation continues - It has a layer of sludge underneath the clay and is being excavated.
- There will be about 10,000 tests done by the time the project is complete
- Final Site Preparation Remains
- Culverts for drainage will be installed
- Completion Still Scheduled for September
- Lagoon will test under 1ppm
Neal's Dump
Final contouring and seeding is done.
ICC Springs
Work is under way, but it has been hard to schedule concrete. A building should be in place this fall.
Equipment in the building will be installed this winter and the plant should be running next spring. The project will cost between 5 and 6 million dollars.
Two culverts were installed under the railroad tracks, one for clean ground water, and one for contaminated water, which is channeled to the plant.
Bennett's Dump
Finalizing Remedial Action Work Plan - Cleanup standard to be 25 to 50 ppm PCB maximum with a soil cover
Sampling is completed - Area outside of fence was tested too
CBS has project out for bids
Mobilization should begin at the end of July
20 to 30,000 cubic yards of material are expected to be removed
Neal's Landfill
North Slope area is Completed - under 5ppm
North Excavation started
Areas outside of the fence have been excavated and verified less than 1ppm.
No capacitors found outside of fence
Tire Shredder has begun working
Capacitors shipped for incineration in Texas - 222,720 Pounds (~2000 Capacitors)
TSCA Soils shipped to EQ - 4,362 Tons
Three types of waste
- Over 500ppm and is shipped offsite
- 500ppm or less - Material is retested - if over 500ppm, it is shipped offsite, if less, it is consolidated - to date, 70% of resampled material has gone offsite.
- All this is consolidated
- Wastewater Treated - 30,080 gallons with 0 gallons discharged
- No Sinkholes found in area
- Phased approach - first deal with removal/consolidation, then water treatment and sediment removal.
- Southeast corner of landfill - All trash will be removed to be consolidated, everything there is getting wet.
- Cleanup average is to be 25 ppm, with 1ppm around wet areas such as ditches and culverts. 5 ppm is the standard for areas around the landfill (outside the fence.)
- Gross Hotspot Removal
- There is currently a dearth of trucks, so material is being excavated, and then covered until loading.
- Misters have been installed at the load out area to retard dust and volitilized PCBs
- Wetted soil will maximize volitilization, but dust borne PCBs may be more harmful, higher in chlorine atoms, more likely to be absorbed. So wetting the pile may be best, but not necessarily good.
- Air Monitoring - 1 day greater than Action level of 1 mg/m3
- Air Monitors check for both dust-borne and volitile PCBs
- CBS upgraded controls
- Personnel Monitoring all under Action Level
- Residential Well Sampling Around Neal's Landfill to begin
- Testing will be for PCBs and VOCs
- A Few nearby springs will be included
- Taylor Spring, Branham Spring, Pig Pen Spring should non-detect for PCBs
- Southside of watershed needs additional data, additional testing
- North Slope is graded and seeded
- Misc. Comments
- There are still issues at Neal's Landfill, and EPA will be working on them for years.
- Sediment removal and water treatment plans have yet to be worked out
- Rolloff boxes are now covered to prevent migration of PCBs.
- There are not enough trucks coming to the sites to keep up with the work getting done.
- Discussing digging at south springs to capture water.
- Diversion ditches will surround the final footprint of the consolidated material.
