1.0 INTRODUCTION This Monthly Progress Report is submitted in accordance with the ADMINISTRATIVE ORDER ON CONSENT (AOC) FOR REMOVAL ACTION Proceeding Under Sections 104, 106(a), 107, and 122 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), as amended, 42 U.S.C. SS 9604, 9606(a), 9607, and 9622 (United States Environmental Protection Agency (U.S. EPA) Docket No.: V-W-'03-C-747) effective July 31, 2003. The next Monthly Progress Report, for the month of June 2008, will be submitted on or before July 15, 2008.
2.0 SIGNIFICANT DEVELOPMENTS IN THIS MONTH • Air monitoring has continued. Final validated results of the creek Removal Action (RA) air-
monitoring program for May 2008 are presented in Table 1.1a (polychlorinated biphenyl (PCB) results) and Table 1.1b (total suspended particulate (TSP) Stations 25C, 28A, and 32B). The locations of the air monitoring stations in the Downstream Parcels are presented on Figure 1.
• Verification results are presented on Figures 2 through 14 to show progress as of this reporting period. Work completed in the parcels, as presented, is not complete as either additional excavation or statistical evaluation may be required to confirm the cleanup objective has been met. Verification figures for a given parcel are included in the monthly report as new data become available until all cleanup criteria are met, whereupon the figure is presented with validated data. Final verification figures will be presented in the Downstream Parcels Construction Certification Report.
• Work continued in May 2008 along the stream channel of Parcels 36, 37, 38, 39, 40, and 81 to remove impacted soil and sediment from the creek channel and floodplain. Confirmation sampling was conducted on the following excavated parcels:
- Parcel 36 on May 1, 13, 15, and 19, 2008, as presented on Figures 2 and 4. - Parcel 37 on May 1, 2008, as presented on Figure 5. - Parcel 38 on May 5, 2008, as presented on Figure 3. - Parcel 39 on May 1, 13, 15, 21, 22, and 30, 2008, as presented on Figures 6, 7, 8, 10,
12, and 14. - Parcel 40 on May 2, 7, 12, 15, and 22, 2008, as presented on Figures 9, 13, and 14. - Parcel 81 on May 2, 12, and 30, 2008, as presented on Figure 11. - Figures 15, 16, 17, and 18, depict key-maps of verification area grids for the

• A total of 32,502 tons of <50 mg/kg PCB material was moved from Staging Area G and placed in approved fill areas within the East Plant Area in May 2008.
• The summary of PCB soil disposal for May 2008 is presented in Table 2.1. The transportation and disposal summary for the <50 mg/kg PCB soil is presented in Table 2.1a
• Water within the remediation areas was collected and treated by ENTACT Environmental Services’ (ENTACT’s) and/or Sevenson Environmental Services’ (SES’s) on-Site water treatment systems. U.S. EPA has approved direct discharge of treated water from both ENTACT’s treatment system at Staging Area F and SES’s treatment system at Parcel 216 Staging Area. Water treatment sample results for ENTACT’s and SES’s treatment systems for May 2008 are provided in Table 3.1 and 3.2, respectively.
• Operation of Borrow Area 39-1 continued. • Restoration of Parcels 29-37 began. • Tree consolidation, chipping, and mulching continued. • A conference call was held on May 13, 2008, with U.S. EPA, Agency for Toxic Substance and
Disease Registry (ATSDR), the Indiana Department of Environmental Management (IDEM), and the Indiana State Department of Health (ISDH) to discuss items related to the RA and the design and construction of the East Plant Area Interim Measures (IM). The United States Fish and Wildlife Service (USFWS) was also invited to the call.
• On-Site construction meetings for the reporting period have been held informally daily and formally weekly. Meetings with SES are generally held on Wednesdays. SES meetings were held on May 1, 7, 14, 21, and 30, 2008. Meetings with ENTACT are held generally on Thursdays. The ENTACT meeting was held on May 1, 8, 15, and 22, 2008. There was no meeting on May 29, 2008. Restoration meetings (SES) are generally held on Wednesdays. SES Restoration meetings were held on May 7, 14, 21, and 28, 2008. Meeting minutes for these meetings can be found in Appendix B.

3.0 SUMMARIES OF ALL ANTICIPATED PROBLEMS AND PLANNED RESOLUTIONS
• GM continues to evaluate the Spring 018 Area. This spring water is currently captured and
treated before entering the creek. - A report summarizing Site Source Control (SSC) Work Plan: Addendum No. 5 and
the investigation/evaluation of the Spring 018 area alternatives will be prepared. - At approximately 3:15 pm on May 7, 2008, the pump sending Spring 018 water to the
SES treatment system was shut off to prevent overflow of the system. Storms continued through May 8, 2008 with flow from the project areas continuing to be contained, but using up any available treatment capacity. Spring 018 was contained by 4:00 p.m. on May 9, 2008. A sample of the spring water was collected. A reportable quantity (RQ) was not exceeded.
- At approximately 9:30 am on May 30, 2008, it was observed that water had backed up in the berm surrounding Spring 018 and was trickling over the top of the berm. A portion of the screen on the pump was blocked with poly sheeting that had come loose during the previous rain event. The overflow was contained by 10:00 am the same day. Upon review of the site inspection log, it was noted that the pump was operating properly as of 8:30 am that same day. A sample of the spring water was collected. A reportable quantity (RQ) was not exceeded. A representative from Hydrogeology Inc, Earth Tech, and CRA inspected the Spring 018 Area in May 2008 and did not find any new conditions that may be contributing to the increase in discharge at Spring 018C. The increase in flow is likely due to the unusually large amount of rainfall and existing saturated conditions.
• There was an unexpected high intensity rain event that caused overflow to the creek on May 27, 2008. - 1.92 inches of rain fell within a 45 minute period with a total of 2.4 inches of rain over a
10 hour period: o The berm containing the remediation water from the grading fill area south of the
water treatment plant, overflowed for approximately 1 hour and 20 minutes between 3:00 to 3:15 pm. This water, combined with the stormwater from clean clay cover areas in Detention Basin 5 (DB5), was released to the creek. At approximately 5:35 pm, the flow from DB5 to the creek was contained. The overflow water was sampled. Water from DB5 continues to be collected and treated. A RQ was not exceeded.
o Water from the impacted fill area on the north side of the Site began to overflow at approximately 3:20 pm and was contained at approximately 4:10 pm. This water flowed into DB3 which flowed into DB4, along with stormwater from GM Drive and the clean clay covered areas. DB4 began to overflow to the creek at approximately 3:20 pm and flow into DB4 was contained at approximately 5:35 pm. Residual water

013968 (277) CONESTOGA-ROVERS & ASSOCIATES
entering into DB4 from surface water caused DB4 to overflow until approximately 8:45 pm. The overflow water was sampled. Water from DB4 continues to be collected and treated. A RQ was not exceeded.
o Spring 018 and Wet Wells 1, 2, and 3 were contained. o A total of 35.27 inches of rain has fallen between January and June of this year. The average
rainfall for the entire year is 46.79 inches.
4.0 PROJECTED WORK FOR THE NEXT REPORTING PERIOD • The following is a list of anticipated work for the next reporting period:
− Continue excavation in the Downstream Parcels (ENTACT work area); − Continue operation of Borrow Area 39-1; − Continue tree consolidation, chipping, and mulching; − Continue road repair work, as needed; − Submit SSC Investigation Summary and Remedial Alternatives Review Report
summarizing studies completed in the Spring 018 Area; − Continue to collect and treat water from DB4 and DB5 until damage to the detention
basins can be assessed (from a cross contamination standpoint); − Remove additional trees in work areas on Parcels 40 and 81; − Resume transportation of the <50 ppm soil from the creek in the approved East Plant
Area fill areas; − Dispose ≥50 mg/kg RA soils from the creek at the Heritage Landfill in Roachdale,
Indiana; − A road meeting will be held with residents along the truck haul route on June 17, 2008; − Meetings will be held with the neighbors and the public on June 18 and 19, 2008; and − A meeting will be held with the CLP on June 20, 2008.

GENERAL NOTES:(1). Cleanup Criteria
a.) Soils to 1.8 mg/kg.- if all results are < 5.0 mg/kg, the cleanup objective can be verified in the Verification Area (approximately 100ft x 200ft) bycalculating the Upper Confidence Limit (UCL) of the average concentration using statistics, if the UCL is 1.8 mg/kg the cleanupobjective will be met for the given Verification Area. A value of 0 mg/kg is used in the UCL calculation for sample grids excavatedto bedrock.
b.) Sediments to 1 mg/kg.(2). Composite sidewall samples were collected in the location where the sidewall of the excavation exceeded 6 inches in height.(3). The surficial confirmation samples (8 composites per Verification Area except where bedrock is encountered) were collected after thesoil/sediment removal was performed.(4). A value of 0 mg/kg is used for ND in the calculation of Total PCBs.(5). For UCL calculations, Aroclors 1016, 1221, and 1232 have been assigned a ND value of 0 mg/kg based upon their lack of presence in thedata.
- UCL calculations are performed on Aroclors 1242, 1248, 1254, and 1260 using half the quantitation limit where ND results are reported.- UCL calculations included both floor and sidewall samples.
(6). The sampling round (e.g. R1, R2, etc.) correlates to Verification Area grids or sidewalls where additional rounds of excavation werecompleted due to exceedances of the cleanup criteria.(7). Property boundary locations approximated from the Lawrence County survey plats. Locations may not accurately represent the trueproperty boundaries.(8). The verification figure is presented to show progress for this reporting period. Excavation verification may not be complete as statisticalanalysis or further excavation may be required.

GENERAL NOTES:(1). Cleanup Criteria
a.) Soils to 1.8 mg/kg.- if all results are < 5.0 mg/kg, the cleanup objective can be verified in the Verification Area (approximately 100ft x 200ft) by calculating the UpperConfidence Limit (UCL) of the average concentration using statistics, if the UCL is 1.8 mg/kg the cleanup objective will be met for the givenVerification Area. A value of 0 mg/kg is used in the UCL calculation for sample grids excavated to bedrock.
b.) Sediments to 1 mg/kg.(2). Composite sidewall samples were collected in the location where the sidewall of the excavation exceeded 6 inches in height.(3). The surficial confirmation samples (8 composites per Verification Area except where bedrock is encountered) were collected after the soil/sediment removalwas performed.(4). A value of 0 mg/kg is used for ND in the calculation of Total PCBs.(5). For UCL calculations, Aroclors 1016, 1221, and 1232 have been assigned a ND value of 0 mg/kg based upon their lack of presence in the data.
- UCL calculations are performed on Aroclors 1242, 1248, 1254, and 1260 using half the quantitation limit where ND results are reported.- UCL calculations included both floor and sidewall samples.
(6). The sampling round (e.g. R1, R2, etc.) correlates to Verification Area grids or sidewalls where additional rounds of excavation were completed due toexceedances of the cleanup criteria.(7). Property boundary locations approximated from the Lawrence County survey plats. Locations may not accurately represent the true property boundaries.(8). The verification figure is presented to show progress for this reporting period. Excavation verification may not be complete as statistical analysis or furtherexcavation may be required.

GENERAL NOTES:(1). Cleanup Criteria
a.) Soils to 1.8 mg/kg.- if all results are < 5.0 mg/kg, the cleanup objective can be verified in the Verification Area (approximately 100ft x 200ft) by calculating the Upper ConfidenceLimit (UCL) of the average concentration using statistics, if the UCL is 1.8 mg/kg the cleanup objective will be met for the given Verification Area. A value of0 mg/kg is used in the UCL calculation for sample grids excavated to bedrock.
b.) Sediments to 1 mg/kg.(2). Composite sidewall samples were collected in the location where the sidewall of the excavation exceeded 6 inches in height.(3). The surficial confirmation samples (8 composites per Verification Area except where bedrock is encountered) were collected after the soil/sediment removal was performed.(4). A value of 0 mg/kg is used for ND in the calculation of Total PCBs.(5). For UCL calculations, Aroclors 1016, 1221, and 1232 have been assigned a ND value of 0 mg/kg based upon their lack of presence in the data.
- UCL calculations are performed on Aroclors 1242, 1248, 1254, and 1260 using half the quantitation limit where ND results are reported.- UCL calculations included both floor and sidewall samples.
(6). The sampling round (e.g. R1, R2, etc.) correlates to Verification Area grids or sidewalls where additional rounds of excavation were completed due to exceedances of thecleanup criteria.(7). Property boundary locations approximated from the Lawrence County survey plats. Locations may not accurately represent the true property boundaries.(8). The verification figure is presented to show progress for this reporting period. Excavation verification may not be complete as statistical analysis or further excavation may berequired.

GENERAL NOTES:(1). Cleanup Criteria
a.) Soils to 1.8 mg/kg.- if all results are < 5.0 mg/kg, the cleanup objective can be verified in the Verification Area (approximately 100ft x 200ft)by calculating the Upper Confidence Limit (UCL) of the average concentration using statistics, if the UCL is 1.8 mg/kgthe cleanup objective will be met for the given Verification Area. A value of 0 mg/kg is used in the UCL calculation forsample grids excavated to bedrock.
b.) Sediments to 1 mg/kg.(2). Composite sidewall samples were collected in the location where the sidewall of the excavation exceeded 6 inches in height.(3). The surficial confirmation samples (8 composites per Verification Area except where bedrock is encountered) were collected afterthe soil/sediment removal was performed.(4). A value of 0 mg/kg is used for ND in the calculation of Total PCBs.(5). For UCL calculations, Aroclors 1016, 1221, and 1232 have been assigned a ND value of 0 mg/kg based upon their lack ofpresence in the data.
- UCL calculations are performed on Aroclors 1242, 1248, 1254, and 1260 using half the quantitation limit where NDresults are reported.- UCL calculations included both floor and sidewall samples.
(6). The sampling round (e.g. R1, R2, etc.) correlates to Verification Area grids or sidewalls where additional rounds of excavation werecompleted due to exceedances of the cleanup criteria.(7). Property boundary locations approximated from the Lawrence County survey plats. Locations may not accurately represent thetrue property boundaries.(8). The verification figure is presented to show progress for this reporting period. Excavation verification may not be complete asstatistical analysis or further excavation may be required.

EXCAVATION FLOOR SAMPLE RESULTS
GENERAL NOTES:(1). Cleanup Criteria
a.) Soils to 1.8 mg/kg.- if all results are < 5.0 mg/kg, the cleanup objective can be verified in the Verification Area (approximately 100ft x 200ft) by calculating the Upper ConfidenceLimit (UCL) of the average concentration using statistics, if the UCL is 1.8 mg/kg the cleanup objective will be met for the given Verification Area. A valueof 0 mg/kg is used in the UCL calculation for sample grids excavated to bedrock.
b.) Sediments to 1 mg/kg.(2). Composite sidewall samples were collected in the location where the sidewall of the excavation exceeded 6 inches in height.(3). The surficial confirmation samples (8 composites per Verification Area except where bedrock is encountered) were collected after the soil/sediment removal was performed.(4). A value of 0 mg/kg is used for ND in the calculation of Total PCBs.(5). For UCL calculations, Aroclors 1016, 1221, and 1232 have been assigned a ND value of 0 mg/kg based upon their lack of presence in the data.
- UCL calculations are performed on Aroclors 1242, 1248, 1254, and 1260 using half the quantitation limit where ND results are reported.- UCL calculations included both floor and sidewall samples.
(6). The sampling round (e.g. R1, R2, etc.) correlates to Verification Area grids or sidewalls where additional rounds of excavation were completed due to exceedances of thecleanup criteria.(7). Property boundary locations approximated from the Lawrence County survey plats. Locations may not accurately represent the true property boundaries.(8). The verification figure is presented to show progress for this reporting period. Excavation verification may not be complete as statistical analysis or further excavation maybe required.

Soils to 1.8 mg/kg.- if all results are < 5.0 mg/kg, the cleanup objective can be verified in the Verification Are (approximately 100ft x 200ft) by calculating theUpper Confidence Limit (UCL) of the average concentration using statistics, if the UCL is 1.8 mg/kg the cleanup objective will be met forthe given Verification Area. A value of 0 mg/kg is used in the UCL calculation for sample grids excavated to bedrock.
b.) Sediments to 1 mg/kg.(2). Composite sidewall samples were collected in the location where the sidewall of the excavation exceeded 6 inches in height.(3). The surficial confirmation samples (8 composites per Verification Area except where bedrock is encountered) were collected after the soil/sedimentremoval was performed.(4). A value of 0 mg/kg is used for ND in the calculation of Total PCBs.(5). For UCL calculations, Aroclors 1016, 1221, and 1232 have been assigned a ND value of 0 mg/kg based upon their lack of presence in the data.
- UCL calculations are performed on Aroclors 1242, 1248, 1254, and 1260 using the half the quantitation limit where ND results are reported.- UCL calculations included both floor and sidewall samples.
(6). The sampling round (e.g. R1, R2, etc.) correlates to Verification Area grids or sidewalls where additional rounds of excavation were completed due toexceedances of the cleanup criteria.(7). Property boundary locations approximated from the Lawrence County survey plats. Locations may not accurately represent the true propertyboundaries.(8.) The verification figure is presented to show progress for this reporting period. Excavation verification may not be complete as statistical analysis orfurther excavation may be required.
