10 Overview

During December 2001 General Electric Company (GE) and its contractor Maxymillian Teclmologies Incorporated (MTI) continued work on the Upper 4 Mile Reach Removal Action The primary work included performing response activities to address the presence of dense non-aqueous-phase liquid (DNAPL) in Cell J1 In addition work tasks associated with the Lyrnan Street Source Control activities were continued this month Although the Lylnan Street Source Control activities are not part of the Upper 2 Mile Reach Removal Action as described in the Work Plan they were undertaken to facilitate work in the Upper 4Mile Reach in the vicinity of the Lyman Street Bridge

Weekly status meetings were held on December 3 10 and 17 2001 No work was perfor~ned on December 24 25 and 31 2001 due to the Christmas and New Years holidays

20 Chronological description of the tasks performed

Refer to the figure (Exhibit A) referenced in Section 40 and attached to this report for an orientation of the sheetpile cells and their respective locations

Balk soil renioval activities in Cell 52 were initiated and completed during the month of December The post-removal survey was also performed the results will be reported with the sedinlent relnoval survey results when complete

Response and investigation activities to address the presence of DNAPL in Cell J1 were also continued during the lnonth of December After the centerline sheetpiles were driven deeper (in the inonth of November) the water pumps were turned back on and Cell 51 was dewatered Following dewatering of the cell the low lifting holes were sealed and leaks were plugged along the centerline slleetpiles of Cell J1 The Waterloo source control sheetpile wall installation activities were then initiated

The Waterloo contaimnent wall installation activities began by completing excavation of balk soils and river sediments along the alignment of the source control sheetpile wall in Cell J1 A preliminary survey was then performed to locate the layout of the Waterloo sl~eetpile wall Installation of the sheetpiles for the Waterloo wall was initiated at the downstream wing wall near the Cell J1 sewer crossing Approximately 20 linear feet of sheetpiles were driven in place down the slope of the bank at 90 to form the downstream wing wall Waterloo sheetpile installation then proceeded upstream parallel to the river for a distance of approxilnately 90 feet and then turned 45 up the bank to install approximately 30 feet of tlie upstream wing wall Connector cutoff sheetpiles were driven near the downstream wing wall of the Waterloo wall and the upstream sewer crossing sheetpile wall to provide a sealed connection between the two walls Following installation of the Waterloo sheetpiles the tops of the sheets were cut to design elevation and removed A

work stand for future grouting activities was constructed along the bank side of the Waterloo wall

At the request of the Environmental Protection Agency (EPA) to continue the DNAPL investigation program in Cell J1 and to identifj the depth to the gray fine sand layer (an apparent confining layer) six additional sediment borings were installed in the riverbed Three borings were completed in the dow~lstream riverbed area and three borings were completed in the upstreanl riverbed area In addition a suppleinental survey was performed in Cell IS to record restored riverbed elevations along the centerline sheetpile wall for use in determining final restored elevations and depth of backfill to be placed for Cell JS

Samplingmonitoring activities completed during the 111ont11 of December iilcluded backfill waste characterization air and water column Isolation sand layer backfill samples were collected and submitted for Total Organic Carboil (TOC) and polychlorinated biphenyl (PCB) analysis and a general backfill soil sample was collected and submitted for PCB analysis Waste cllaracterization samples were collected froin the DNAPL-impacted material removed from Cell J l and submitted for analysis of PCBs volatile organic compounds (VOCs) senlivolatile organic compounds (SVOCs) and metals Air rnonitoriilg for particulate matter was conducted on a daily basis The monthly PCB air monitoring event was conducted on Deceinber 13 and 14 200 1 Water colunln [PCB and total suspended solids (TSS)] monitoring was also continued during removal activities in the month of December

During the month of December CE Buildings 33X and 33-north were ~lsed as tenlporary storage facilities for Toxic Substances Control Act (TSCA) material and non-TSCA material respectively prior to final disposition at the appropriate On-Plant Consolidation Area (OPCA) I11 addition Buildiilg 65 and a storage area near Building 68 were used as a temporary storage areas for DNAPL-impacted material removed from Cell JS During December the transfer of excavated TSCA material temporarily staged in Building 33X was initiated and con~pleted The soilisediment was subjected to a paint filter test to confirm that the material did not contain excess water prior to transfer to the Building 71 OPCA In addition approximately 670 tons of DNAPL-impacted nlaterial removed froin Cell JS and temporarily stockpiled in Building 65 and near Building 68 were transported off-site for appropriate disposal

Lyman Street Source Control Activities

Work efforts for the Lyinan Street source control barrier wall installation were continued during December Initial activities involved performance of bank soil removal activities along the wall alignment as well as performance of the Cell 53 bank soil removal activities During removal activities in this area seven piezometers (PI - P7) located near the Waterloo source control wall alignment were removed and abandoned Installation activities for the source control wall began by placing a templatework stand to aid in

locating and driving the Waterloo sheetpiles A preliminary survey was then performed to locate the layout of the Lyman Street source control wall Installation of the sheetpiles for the Waterloo wall began at the downstream end wing wall (near the Lyman Street Bridge) and continued in the upstream direction InitiaIly subsurface obstructions were encountered in the downstream installation area and the obstructions (boulders and a concrete thrust block) were removed to facilitate driving the sheetpiles in this area Approximately 40 linear feet of sheetpiles were driven in place along Lyman Street to form the downstream wing wall Waterloo sheetpile installation then proceeded upstream parallel to the river for a distance of approximately 300 feet and then turned 45 up the bank for approximately 40 feet to form the upstream wing wall The total length of the installed Waterloo source control sheetpile wall is approximately 380 feet

After the sheetpiles were completely driven the tops of Waterloo sheetpiles were trimmed to design elevation and removed In addition the toe of the bank (between the Waterloo source control barrier wall and the silt fence along the edge of the river) was stabilized by placing seed and erosion control mats over the area

work stand for future grouting activities was constructed along the bank side of the Waterloo wall

At the request of the Environmental Protection Agency (EPA) to continue the DNAPL investigation program in Cell J1 and to identifj the depth to the gray fine sand layer (an apparent confining layer) six additional sediment borings were installed in the riverbed Three borings were completed in the dow~lstream riverbed area and three borings were completed in the upstreanl riverbed area In addition a suppleinental survey was performed in Cell IS to record restored riverbed elevations along the centerline sheetpile wall for use in determining final restored elevations and depth of backfill to be placed for Cell JS

Samplingmonitoring activities completed during the 111ont11 of December iilcluded backfill waste characterization air and water column Isolation sand layer backfill samples were collected and submitted for Total Organic Carboil (TOC) and polychlorinated biphenyl (PCB) analysis and a general backfill soil sample was collected and submitted for PCB analysis Waste cllaracterization samples were collected froin the DNAPL-impacted material removed from Cell J l and submitted for analysis of PCBs volatile organic compounds (VOCs) senlivolatile organic compounds (SVOCs) and metals Air rnonitoriilg for particulate matter was conducted on a daily basis The monthly PCB air monitoring event was conducted on Deceinber 13 and 14 200 1 Water colunln [PCB and total suspended solids (TSS)] monitoring was also continued during removal activities in the month of December

During the month of December CE Buildings 33X and 33-north were ~lsed as tenlporary storage facilities for Toxic Substances Control Act (TSCA) material and non-TSCA material respectively prior to final disposition at the appropriate On-Plant Consolidation Area (OPCA) I11 addition Buildiilg 65 and a storage area near Building 68 were used as a temporary storage areas for DNAPL-impacted material removed from Cell JS During December the transfer of excavated TSCA material temporarily staged in Building 33X was initiated and con~pleted The soilisediment was subjected to a paint filter test to confirm that the material did not contain excess water prior to transfer to the Building 71 OPCA In addition approximately 670 tons of DNAPL-impacted nlaterial removed froin Cell JS and temporarily stockpiled in Building 65 and near Building 68 were transported off-site for appropriate disposal

Lyman Street Source Control Activities

Work efforts for the Lyinan Street source control barrier wall installation were continued during December Initial activities involved performance of bank soil removal activities along the wall alignment as well as performance of the Cell 53 bank soil removal activities During removal activities in this area seven piezometers (PI - P7) located near the Waterloo source control wall alignment were removed and abandoned Installation activities for the source control wall began by placing a templatework stand to aid in

locating and driving the Waterloo sheetpiles A preliminary survey was then performed to locate the layout of the Lyman Street source control wall Installation of the sheetpiles for the Waterloo wall began at the downstream end wing wall (near the Lyman Street Bridge) and continued in the upstream direction InitiaIly subsurface obstructions were encountered in the downstream installation area and the obstructions (boulders and a concrete thrust block) were removed to facilitate driving the sheetpiles in this area Approximately 40 linear feet of sheetpiles were driven in place along Lyman Street to form the downstream wing wall Waterloo sheetpile installation then proceeded upstream parallel to the river for a distance of approximately 300 feet and then turned 45 up the bank for approximately 40 feet to form the upstream wing wall The total length of the installed Waterloo source control sheetpile wall is approximately 380 feet

After the sheetpiles were completely driven the tops of Waterloo sheetpiles were trimmed to design elevation and removed In addition the toe of the bank (between the Waterloo source control barrier wall and the silt fence along the edge of the river) was stabilized by placing seed and erosion control mats over the area
