Groundwater quality results from the perfom1ance monitoring wells at the GE and Shepherd Farm Subsite documents the existing contaminant concentrations. At the GE Subsite 1,2 dichloroethane, chlorofom1, tetracholorethene, trichloroethene, vinyl chloride, lead and manganese were found above the remediation goals. At the Shepherd Fann Subsitc tetrachloroethene, lead, and manganese were found above the remediation goals. Nitrobenzene, the only SVOC RTC, was not detected at any of the performance monitoring wells. The GRS has extracted and treated 3 million gallons during the period from April 2001 to June 2001. During this period, 9.73 pounds ofVOCs and 5.59 pounds of metals have been removed. The treatment system is operating effectively with minor interruptions for operation and maintenance activities. Since GRS startup 8.5 million gallons of groundwater have been extracted and treated resulting in the removal of 28.62 pounds of VOCs and 33.06 pounds of metals. Wetland surveys indicate that there has been no significant deterioration to the wetlands, including the bunched arrowhead habitat, from the pumping of the GRS. A more detailed biological assessment of the wetlands will take place in September 2001. The next scheduled sampling event is the September 200 I annual sampling event. Performance monitoring wells, residential wells, surface water, sediment stations, and influent and effluent air and water will be sampled. The wetland survey will also be completed. 5-1 Pc\GE\RGVP\gis-e01WL(IGE.WO< Expla11atio11 0 .;J; Site monitor well ♦ Recovery wel I ,-2150~ Water table elevation contour (2ft msl) as measured on June 4, 2001 300 SCALE IN FEET • • Note_: RW-3 and RW-4 are i~active 6QQ TITLE:· Potentiometric Surface at the GE Subsite on June 4, 2001 ~ -N- I LOCATION: East Flat Rock, NC -G ri DRAFTED PEP ........,. _ e O ran· s eF'-'ll'-E'-"'-f-JU_N_eo_,w_L_@G_E_.W_0-1 2 • 1 □ 4 '"""''"'"""' , Inc. □ATE 01103/01 CHECKED PEP FIGURE: • P:IGE\RGVP\gis-rgvp\xsectAA4rev,WOR " "•<.\ ~ • =·~~~1~~T~~Fi~h~;-~.=7-T~·,,c~=-,=~ MW-29\:--..._;;,'' W-12 \ W-12A \ -12B··, / .\ / \ c5 ~'l,~ " \ '!) ✓• / ;~ :-D:·· ,: ;;_ :c;:; /' ,/ • 2225-·rA ___________________________________ ---,A' 2225 2200 - 2175 - 2150 - 2125 - 2100 - 2075 -· 2050 - 2025 -· .... :-:-~. < N ~ "' 11 Bat Fork Creek 2200 2175 2150 2125 I I 177 2100 2075 108 2050 2025 2000 -'--------------------------------------'-2000 Notes: 1.

The titles of Figures 2-6 through 13 are incorrectly identified in the List of Figures portion of the Table of Contents and should be corrected. Also, color copies of photographs should be used for future reports. The List of Figures portion of the Table of Contents indicates the Figure 2-4 title to be "Location of Stream Flow Measurements" while the actual title of this figure is "Location of Stream F_low measurement Points". Please correct this discrepancy. Titles for Tables 3-3 and 3-4 are incomplete. The words "for March 2001" should be added to each. A space should be inserted between "carolina" and "FED" in the explanation section of Table 1-1 . · 6. The analytical data summarized in Table 3-4 for samples RWSF-1, MW-64, MW-64A, and MW-66 does not correlate to the results presented in the laboratory analytical data sheets for these four samples. This should be corrected. 7. Page 4-1, Section 4.1.1, third paragraph -Condensate should not accumulate in the air phase carbon to the degree that it must be drained daily.

The remediation goals have not been achieved for either the GE or the Shepherd Farm Subsite at the time of the Quarterly Groundwater Remedial Action Performance Monitoring Report -December 2000. No assumptions regarding achievement of remediation goals are intended to be presented in this quarterly report. Separate laboratory analysis for individual volatile organic compounds will not aid in assessment or remedial strategy while PCE concentrations remain more than two orders of magnitude above remediation goals at the GE Subsite. 6.

Continuous operation of the groundwater pump and treat system is preferred. System downtime is sought to be minimized.

"Sample Date" has been changed to 11 Parameter11 • 15. Table 3-3 GE Subsite -Performance Well Analytical Results was prepared and submiited as a means to simply convey a large body of information. The table was not intended to make any assumptions regarding achievement of the remediation goals. All future assumptions regarding achievement of the remediation goals will be clearly explained in the text of the report. While PCE remains at concentrations that are orders of magnitude above its remediation goal, General Electric will not pursue any modification to the remedy of the seven volatile organic compounds (i.e., removing one of the other VOC constituents from the remediation target compound list or changing pumpage ). In an effort to more easily convey information through Table 3-3, detected results above remediation goals were bolded. As noted in the comment, several instances exist in which non-detected compound have both a method detection limit and a reporting limit above their respective remediation goals. These instances all occur in samples which required dilution for proper detection of elevated levels of PCE (i.e., PCE greater than I 00 ug/L). Non-detected compounds were not bolded in this summary table. While valid argument can be postulated that some compounds may be non-detected by the laboratory for several P: \G E\R G. ✓ P\comrcs4 th00 rpt. wpd March 27,'.WOI 2 consecutive quarters but, as the method detection limit is above the remediaiton goal when the sample is diluted, the compound could hypothetically be present above the remediation goal. We would elect to not be argumentative and not hypothesize about the possibility of repeated non-detection of low level contamination. The current analyses are conducted with the appropriate detection limits for this stage of the final remedy. The note on the meaning ofbolded values at the bottom of Table 3-3 will be appended to more precisely define its meaning. Table 3-4 Shepherd Farm Subsite -Performance Well Analytical Results 16.

Table 4-4 has been revised as requested. 21. The purpose of Table 4-4 is to present the estimated mass of remediation target compounds that have been removed by the groundwater remediation system during the first quarter of operation. Table 4-4 lists the mass removed in micrograms, grams, and pounds for convenience. The amount of mass removed each quarter will be useful for comparison as the system continues to operate. Table 4-4 is created by manipulating data in a spreadsheet and may involve averaging, rounding, and summing of numbers. When numbers are summed, the exact value of each is utilized. Adding the rounded values individually is not an accurate method for summation. Therefore the correct value for the GRS design influent concentration-total metals is 665.3 micrograms per liter (ug/1). The relevance of this number is discovered through comparison to the GRS Influent sampled 12/07/00 column. The total metals detected in the influent of the GRS is approximately 90 ug/1 compared to a design of approximately 670 ug/1, therefore actual concentrations P: \G E\R G V P\comres4 th 00rpt. wpd March 27,2001 3 are less than designed. Further inspection of this comparison reveals that manganese concentrations at the Shepherd Farm recovery wells are much less than anticipated. Attachment A Laboratory Reports 22.

Please revise Section 1 to include a reference to Table 1-1 and Table 1-2. Section 3.1 Performance Monitoring Wells -GE Subsite 5. 6. The laboratory quantification limits and subsequent method detection limits (MDLs) used for 1,2-dlchloroethane (1,2-DCA), trichloroethane (TCE), chloroform, and vinyl chloride (VC) analyses at groundwater monitoring wells MW-8, MW-12, MW-12A, MW-128, MW-13A, MW-14, MW-14A, and MW-16A are not adequately low enough to determine whether the remediation goals have been achieved. To make any assumptions regarding achieving the remediation goals, laboratory analysis of groundwater samples at quantitative levels beneath the groundwater cleanup criteria must be made. Separate laboratory runs for the various compounds may be required so that appropriate detection limits are maintained for all analytes. Please make sure that all future analyses are conducted with the appropriate detection limits. The second sentence of the second paragraph slates, "Performance monitoring wells at the GE Subsite indicated the presence of chloroform, 1,2- dichloroethane, cis-1,2-dichloroethene, tetrachloroethene (PCE), trichloroethane (TCE), and manganese at concentrations above remediation goals." The sixth sentence of the second paragraph of Section 3.1 states, "For all remediation target compounds the method detection limit used by Accutest Laboratories is below the remediation goal." However, the laboratory quantification limits and subsequent MDLs used 1,2-DCA, TCE, chloroform and VC analyses at groundwater monitoring wells MW-8, MW-12, MW-12A, MW-12B, MW-13A, -1 - MW-14, MW-14A, and MW-16A are not below their respective remediation goals. Please revise Section 3.1 accordingly. Section 4.1.1 Pumpage Measurements 7. Please revise the last sentence of the third paragraph of Section 4.1.1 to state, "The air stripper is operating as designed and the granular activated carbon unit is free of water." Section 4.1.2 Treatment System Downtime 8. Section 4.1.2 indicates that the Groundwater Remediation System (GAS) was shut down over the holidays because on-site personnel were unavailable to monitor the system. The GAS was designed to operate with alarms, automatic shutoffs and a remote telecommunications system. Please provide justification for not employing these failsafes in lieu of on-site personnel. Why is the system being routinely shutdown during vacation periods (Thanksgiving and Christmas)? It appears that mass transfer limitations are not restricting dissolved concentrations (see Section 7.3 of the Final Design for Groundwater) and therefore continuous operations are preferred to prevent losing hydraulic containment of the plume. Section 4.1.3 GAS Operation and Maintenance 9. In the fourth bullet, When will the repair of the cooling water intake be completed so that system flows can be increased? 10. In the sixth bullet, When the total gallons pumped (2,337,541) taken from Table 4-2 is divided by 105,120 minutes (12 days for October, 30 days for November, and 31 days for December) an average pumping rate of 22 gpm ·1s obtained; not 23 gpm.

This 4th Quarter sampling report addresses the first three months of performance after startup of the Groundwater Remediation System (GRS). Baseline conditions were reported in the Annual Groundwater Remedial Action Performance Monitoring Report -2000 (Geotrans, 2000). The groundwater RA is pump-and-treat. Performance monitoring was performed in accordance with the Remediation Goal Verification Plan (RGVP) contained in the Final Design and Remedial Action Work Plan for Groundwater (HSI Geo Trans, 2000). The performance monitoring data collected in December 2000 includes water-level data, groundwater quality data, treatment system influent and effluent sampling data, and a recovery well and treatment system operation summary. Tables of the remedial goals for groundwater and the limitations for the publically owned treatment works (POTW) are listed in Tables 1-1 and 1-2 respectively. Groundwater RA performance monitoring objectives include: • To assess whether the ongoing RA is adequate in containing the extent of the impacted groundwater. • To measure progress in reduction of contaminant concentration and mass in order to evaluate technical practicability of the remedy for attaining ROD remediation goals. • To assess whether the treatment system is operating as designed. • To assess whether wetlands and sensitive receptors are adversely impacted by groundwater withdrawals. • To provide data, if necessary, to evaluate appropriate modifications to the RA. No biological monitoring of the wetlands was performed during the 4th Quarter sampling event. Wetland monitoring is performed during the first, second and third quarter sampling events in accordance with the RGVP. 1-1 3 WATER-QUALITY MONITORING ACTIVITIES Water-quality data is collected on scheduled intervals (Table 3-1) from the performance monitoring network which is composed of performance monitoring wells, residential wells, surface water monitoring stations, and sediment monitoring stations. Residential wells, surface water monitoring stations, and sediment monitoring stations are sampled annually (September). The performance monitoring wells are sampled quarterly and are illustrated on Figure 3-1 for the GE Subsite and 3-2 for the Shepherd Farm Subsite. Sixteen performance monitoring wells arc located at the GE Subsite. Four performance monitoring wells are located at the Shepherd Farm Subsite. 3.1 PERFOR.t"1ANCE MONITORING WELLS -GE SUBSITE The performance monitoring well network is sampled to assess the effectiveness of the pump-and-treat remedy. Eight measurements, at a minimum, are required before statistically -significant trends will be plotted and analyzed. Performance wells are selected within and downgradiant from the contaminant plume at the GE Subsite (Figure 3-1 ). Different performance wells are screened in the saprolite, the upper bedrock, and the lower bedrock. Table 3-2 lists the screened interval and aquifer layers for the performance monitoring wells at the GE Subsite. • The 16 performance monitoring wells at the GE Subsite were sampled between December 4 and December 7, 2000. Performance monitoring wells at the GE Subsite indicated the presence of chloroform, 1,2-dichloroethane, cis-1,2-dichloroethene, tetrachloroethene (PCE), trichloroethene (TCE), and manganese at concentrations above remediation goals. This is consistent with water quality data collected during the baseline sampling event (Geo Trans, 2000). Table 3-3 presents a summary of the analytical results from the performance monitoring wells from the GE Subsite. Laboratory reports, chain of custody forms for all samples, and an explanation of reporting limits and method detection limits are included in Attachment A. The method detection limit used by Accutest Laboratories for a undiluted sample is below the remediation goal for each remediation target 3-1 compound. However, if a sample is diluted, the lower quantification limit is increased by the dilution factor. Time-concentration plots for the performance monitoring wells are included in Attachment e. Time-concentration tables for individual wells are included in Attachment D. Figure 3-3 depicts a cross section of the GE Subsite showing depth and PeE concentration for select performance monitoring wells. Other voes were detected (as shown in Attachment A) but PeE is historically the voe with the greatest concentration and serves as a useful indicator voe parameter. Nitrobenzene, the one SVOe in the RTe list, was not detected at the GE Subsite. 3.2 PERFORMANCE MONITORING WELLS -SHEPHERD FARM SUBSITE Performance wells have been selected along the downgradient and peripheral portions of the contaminant plume at the Shepherd Farm Subsite (Figure 3-2). Three performance wells are screened in the saprolite and one in the upper bedrock. Table 3-2 lists the screened interval and hydrogeologic unit for the performance monitoring wells at the Shepherd Fam1 Subsite. The four performance monitoring wells at the Shepherd Farm Subsite were sampled between December 4 and December 7, 2000. Performance monitoring wells at the Shepherd Farm Subsite indicated the presence of PeE, lead, and manganese at concentrations above remediation goals. PeE and manganese have historically been detected above remediation goals at the Shepherd Farm Subsite. The occurrence of lead at RWSF-1 at a concentration of 51 (remediation goal is 15) represents the first exceedance of lead at the Shepherd Farm Subsite performance wells. Lead has been detected previously in background wells. Table 3- 4 lists the analytical results from the Shepherd Farm Subsite. Laboratory reports, chain of custody forms for all samples, and an explanation of reporting limits and method detection limits are included in Attachment A. In all cases the method detection limit used by Accutest Laboratories is below the remediation goal. Time-concentration plots for the performance monitoring wells are included in Attachment e. Time-concentration tables for individual wells are included in Attachment D. Nitrobenzene, the one SVOe in the RTe list, was not detected at the Shepherd Farm Subsite. 3-2 4 SUMMARY OF TREATMENT SYSTEM ACTIVITIES 4.1 GRS OPERATION 4.1.1 PUMPAGE MEASUREMENTS Total flow measurements have been collected monthly from all recovery wells and for the treated effluent from the treatment building. Table 4-1 lists the measured pumpage from each recovery well. Table 4-2 lists the measured effluent water from the treatment building. The sum of the individual recovery wells should equal the total flow through the treatment building. The difference between the sum of individual recovery wells and total flow at the treatment building is 9.6% in November and 3.9% in December (Note: a one day difference in measurement recording is equivalent to a 3.3% difference). The differences are attributed to measurements being recorded one day apart and malfunctioning flow totalizers at R W-1 and RW-2. Adjustments have been made so that flow at RW-1 and RW-2 are metered correctly. The average flowrate of treated groundwater was 26.5 gallons per minute (gpm) in November and 19.2 gpm in December. The overall flow rate is less than expected. This is due to several days of downtime, RW-1 becoming non-operational, repairs required for the cooling water intake inside the GE manufacturing plant which limited the amount of process water that could be accepted, and the overall drop in groundwater levels affecting the initially- set pumping rates. GeoTrans performed operation and maintenance activities including fixing the submersible pump in R W-1 and increasing recovery well flow rates in January 200 I. The treatment system and its components (i.e., bag filters, air stripper, granular activated carbon unit, system controls, and system alarms) are operating as designed. Bag filter replacement has reduced from daily to bi-weekly since initial start-up. The air stripper is operating as designed and the granular activated carbon unit is free of water. 4-1 • 4.1.2 TREATMENT SYSTEM DOWNTIME The treatment system was down from November 23, 2000 through November 27, 2000 over the Thanksgiving holidays and from December 23, 2000 through January 2, 2001. On-site personnel were not available to monitor the system during these times and decided to tum off the system to avoid the possibility of treatment system failure while personnel were not available. A treatment system slow-down was required while one of the two cooling towers inside the GE manufacturing plant was repaired. Capacity for process water was decreased during this repair and forced a decrease in flow through the treatment system. This cooling tower repair has not historically been a regular event and is expected to be a rare occurrence. The treatment system did not experience any equipment related downtime. 4.1.3 GRS OPERATION AND MAINTENANCE During the first three months of operation, the following adjustments and repairs have been required: • Replacement of RW-1 submersible pump. Shaft of existing pump was sheared. Submersible pump from RW-3 was used as a replacement pump and installed in RW-1 on January 30, 2001. • Repair of flow meter at R W-1. Flow meter was not accurately recording low flow rates. Problem detected at end-of~month flow meter reading. Flow rate was increased when replacement pump was installed and meter was working when inspected on January 3 1, 2001. • Repair of flow meter at RW-2. Flow meter was not accurately recording low flow rates. Problem detected at end-of-month flow meter reading. Flow rate was increased in early January 200 I and meter was working when inspected on January 31, 2001. • Repair of cooling water intake inside the GE manufacturing plant. During repair, flow through the GRS was decreased. RW-6 and RW-7 were turned off on a rotating basis during late November and early December to decrease flow rates . 4-2 • Iron bacteria in RWSF-2, RWSF-3, and RWSF-4 have required frequent bag filter replacements. The three affected wells were surged and treated with a Clorox disinfectant on January 29-31, 200 I. Additional treatment is scheduled for the week of March 5, 2001. • Average flow through the GRS during the first three months of operation, during days of operation, was approximately 28 gallons per minute. When considering downtime, average flow rate was approximately 22 gallons per minute. The metering valves controlling flow have been adjusted to increase flow at RW-1, RW-2, RW-7, and RWSF-4 to thereby increase the average flow through the GRS. The design flow is 32 gallons per minute. 4.2 TREATMENT SYSTEM EFFLUENT MONITORING The treatment system effluent water and effluent air are sampled during operations to ensure proper function of the air stripper, to ensure remediation goals are met, and to ensure POTW requirements are met. Extracted groundwater is treated for VOCs and SVOCs using an air stripper. The air used in the stripping process is then forced through a granular activated carbon unit prior to discharge to the atmosphere. Treated groundwater is piped to the GE facility for use as process water, pretreated for metals, and discharged to the POTW. GE samples the process water before final discharge to the POTW. Influent and effluent water samples were collected on December 7, 2000. Laboratory reports are included in Attachment A. Eff1uent water samples (Table 4-3) for VOCs and SVOCs were collected within the treatment building after treatment by the air stripper on December 7, 2000. Effluent samples for metals were collected after metals pretreatment prior to POTW discharge. Laboratory results indicate that the air stripper is operating correctly and that all RTCs are non-detect or below remedial goals. In general, total influent VOC concentrations were 31 percent higher than expected and total influent metals were 86 percent lower than expected. Table 4-4 lists the GRS design influent concentrations compared to the sampled influent concentration. Several VOCs, including benzene, chloroform, trans-1,2-dichloroethene, and tetrachloroethene, have -concentrations greater than the designed concentration. No nitrobenzene has been detected in 4-3 the influent which is less than the design concentration of2.3 ug/L. Several metals, including barium, lead, manganese, and nickel, have concentrations lower than designed. Vinyl chloride, nitrobenzene, beryllium, lead, and nickel were not detected in the influent. Influent water quality measurements (Table 4-3) are used in conjunction with pumpage rates to estimate mass removal due to operation of the GRS. Quarterly removal rates will be plotted and compared after continuing operation of the GRS. Table 4-4 lists the estimated mass removal for the RTCs. Vinyl chloride, nitrobenzene, beryllium, lead, and nickel were all non-detect in the influent samples. Therefore their respective total pounds removed cannot be calculated. PCE has the highest estimated mass removal, totaling 8.33 pounds in the first quarter of operation. Among the metals, barium and manganese have the highest estim.ited removal totaling 1.20 lbs and 0.59 lbs respectively. Effluent air samples were not taken during the December sampling event. The treatment system effluent air samples are collected twice a year (September and March) in accordance with the RGVP (HSI GeoTrans, 2000). 4-4 • • Table 3-3.

RESPONSE A certification of completion has been included between the Executive Summary and the Introduction of the Report. The certification of completion follows the specifications in the Consent Decree. A signed and sealed survey of the pipeline, recovery wells, electric boxes, well vaults, and reference points has been included as requested. A signed and sealed as built drawing of the treatment building has been included. Also as built drawings of all recovery wells, well vaults, and electrical diagrams are included in the appropriate appendi<;es. The report states in Section 4 Operation and Maintenance that all system changes must be approved by EPA and NC DENR. No operational procedures are anticipated to be modified at this time. Performance monitoring and the associated schedule, list of wells, and I ist of analytes is described in the Remediation Goal Verification Plan (Appendix F -Final Design and Remedial Action Work Plan for Groundwater, June 2000). IfGE does seek a change to the execution of the final remedy (i.e. Removal of nitrobenzene as a remediation target compound at the Shepherd Farm Subsite), GE will request written authorization from EPA. This precedent has been established as most recently demonstrated in GE's request and EPA' s subsequent approval to abandon two monitoring wells at the Shepherd Farm Subsite. As a clarifying note, the Consent Decree is a binding legal document between only two parties, GE and EPA. Table of Contents /4. Section I /-). /6. }7.

Groundwater contouring is correctly performed using appropriate kriging methods, applied to the stated data. No interpretation of the spatial correlation of groundwater concentrations in the vicinity of R W-4 is implied. (i.e. Is this a hot spot?). For future correspondence please indicate the Agency's technical definition of a hot spot. Screened intervals and depth of pump probes for RW-1 and RW-2 added to Table 2-2.

Together this data shows that less than IO samples were taken between calibrations and that moisture corrections were not needed. The compaction testing was accepted based on a combination of field testing and on-site inspection. As noted in the table, two areas were unable to attain the specified compaction of95% of the maximum dry density for the listed reasons. In these areas, each lift in the area was compacted a minimum of ten times using a walk-behind roller or vibratory plate. In all areas that were tested to be less than I 00% of the maximum dry density, an additional two passes were completed using a walk-behind roller or vibratory plate. Retesting was not performed. General Electric holds its contractor to a performance guarantee for all completed work. As an example of this, the contractor is scheduled to return to the site the week of April 23,200 I to add and compact soil in the area of SF-4 through SF-13 due to subsidence.

However, the Field Log Notes included as Attachment 5 of Appendix B indicates the following: At 1900 on July 27, 2000, Groundwater Treatment Authority (GTA) [sic] "hit wires." - 2 - NORTH SUPERFUND ro: MAR 12'01 10:52 No.001 P.04 At 1400 on August 10, 2000, trenching from the fence toward the asphalt drive resulted in slight damage to a 3-inch diameter polyvinyl chloride (PVC) return/discharge pipe to the General Electric (GE) plant. Although the line was repaired at 1600, the system was restarted prior to opening the plant valve, causing flooding in the plant and resulting in additional repairs. At 1710 on August 15, 2000, trenching activities uncovered a former drainage line from the former Dry Sludge lmpoundment (OSI) as well as a second conduit that required repair. At 1130 on August 17, 2000, trenching activities break a fiberglass drain line near the pump house. Groundwater Treatment Technologies (GWTT) subsequently conducted the necessary repairs. At 1500 on August 17, 2000, trenching activities hit a wire in the "junk yard." GE was contacted and the wire was determined to be from a former underground storage tank (UST), long since removed. At 1500 on September 12, 2000, well vault installation near extraction well RW-6 cut a telephone wire that was subsequently repaired by GE. Although it appears that none of these lines were marked by the various utility locating services and that none of the disruptions caused major damage, please revise Section 2.1.2 to briefly detail these incidents, the repairs made, as well as the standard caveats regarding the location of on-site utilities and the repair of such utilities. Section 2.3 Clearing, Grubbing, and Erosion Control 14. Section 2.3 indicates that trees, shrubs and pavement were removed dur"1ng the construction of the Groundwater Remediation System (GRS). Please name the disposal facility where these materials were disposed and include the bills of lading in Appendix Band/or Appendix C. Section 2.2 Recovery Well Construction 15. The second paragraph of Section 2.2 indicates that the location of recovery well RW-6 was moved because the boring drilled at the originally proposed location failed to generate substantial amounts of water. Please revise the second paragraph of Section 2.2 to include a statement or statements regarding the groundwater modeling conducted to ensure that the new location of recovery well RW-6 will not significantly change the contaminant hydraulic containment or cause adverse impacts to the bunched arrowhead habitat. - 3 - NORTH SUPERFUND ID: MRR 12'01 10:53 No.001 P.05 16. Please revise the third paragraph of Section 2 .2 to include a brief description of air rotary and water rotary drilling methods. 17. The fourth paragraph of Section 2.2 describes the collection of soil cuttings generated during recovery well installation. Please revise Section 2.2 to indicate the volume of cuttings generated from the GE and Shepherd Farm Subsites. 18, The fourth sentence of the fourth paragraph of Section 2.2 indicates that soil cutting samples were collected from the roll-off bins and analyzed for volatile organic compound content. Please revise this sentence to describe the soil sampling process, including the collection of grab samples versus the collection of composite samples. 19. Please revise the ninth sentence of the fifth paragraph of Section 2.2 to state, "After the bentonite cured for a minimum of eight hours, the wells were grouted from the top of the bentonite seal to 4 feet below ground surface to allow for installation of the pitless adapter and well vault." 20. The ninth sentence of the fifth paragraph of Section 2.2 indicates that the wells were grouted from the top of the bentonite seal to 4 feet below ground surface to allow tor installation of the pitless adapter and well vault. However, the top of the bentonite seal tor recovery well RW-7 is located one foot below ground surface (bgs).

Section 2.6 Startup/Shakedown 29. 30. The sixth sentence of the third paragraph of Section 2.6 states, "Head measurements and pumping rates in the recovery wells were made hourly for the first eight hours of operation and twice daily thereafter for the remainder of startup (Table 2-5)." However, Table 2-5 indicates that the approved startup/shakedown procedures were only implemented at recovery wells RWSF- 2, RWSF-3, and RWSF-4. The startup/shakedown procedures for recovery wells RW-2, RW-6, and RW-7 roughly complied with the approved procedures although Table 2-5 indicates that the pumping rates were intermittent initially. The startup/shakedown procedures for recovery wells RW-1, RW-5, and RWSF- 1 did not comply with the approved procedures as the pumping rates were not maintained with any sort of consistency (or at all}. The startup/shakedown procedures for these recovery wells should not have been initiated until the recovery wells were truly ready for operation. Please revise Section 2.6 to include a justification for not complying with the regulatory-approved startup/shakedown procedures and initiating startup/shakedown procedures before construction of the recovery wells had been completed. This section contains only a brief description of the testing of alarms and fail- safes. More information (in the form of tables, etc.) is needed.
