Neal's Landfill
- USGS overflow gauging stations in place,
- Measures small storm on 6-16&6-18
- Automatic sampler will be used during storm events.
- Measuring overflow 0, overflow 1 &2, overflow 3&4 and north spring, which has not been measured till now.
- CBS will measure south spring, culvert, and Conards Branch
IC Springs WT Plant
Treatment Plant is fully operational
Effluent non-detect for PCBs 0.1ppb
Storage tanks not usable until construction issues resolved.
100gal/minute bypassed 6-17-00 due to not having tanks.
- Tanks are made with plates that are bolted and the gaskets are not working.
Has onsite generator used twice due to lost power.
Bennett's Dump
- Sediment Sampling begins June 26, 2000
- Sampling along site and banks
- EPA will sample farther downstream
- Removal plan will be devoloped based on sampling at 1 ppb for site and downstream.
- Site maintenance and groundwater monitoring plan also remain.
Lemon Lane
- Consolidation completed on west, north and east, thus shrinking size of the landfill
- Aprox. 25,000 yards of material excavated and placed around perimeter
- Only 7 capacitors and 1 winding found on north side
- Dug out north side of sink hole
- 2780 tons shipped out to-date
- Started hotspot excavation at SB-08
- 47+ capacitors found at SB-08
- Started excavation on southwest corner 86 total capacitors found
- Air Monitoring
- North 403.7 ng/m3
- East 332.8 ng/m3
- SE 346.1 ng/m3
- West 36.7 ng/m3
- 3 monitors greater than 1000ng/m3 for 3 days in early June from the consolidation piles 2nd, 5th, and 8th
- EPA made CBS cover the consolidation pile.
- Dust and vapor are measured, with 48 hour turnaround.
- Additional actions taken to reduce emissions.
- Risk levels under 1 in one million excess cancer risk, non cancer risks are acceptable.
- EPA funded summa canisters non-detect for VOCs.
- Portable GC detected low levels of toluene
- CBS has complete 44 additional boring ins southeast part of landfill
- Data shows SE corner extremely high PCB levels to bedrock (20000\ppm)
- Strong possibility of sinkhole(s) in SE, feeding contamination to ICS
- Earliest aerials show railroad
- CBS is going to collect additional information from below bedrock
- Ideas to address bedrock contamination are underway.
- Removal is needed (in SE corner)
- There will be capacitors left in consolidation area.
