Principal Advisor, Closure & Remediation February 13, 2007 Ms. Rebecca Thomas Remedial Project Manager US EPA Region 8 (EPR-SR) 1595 Wynkoop Street Denver, CO 80202-1129 Mr. Douglas Bacon UDEQ –DERR Project Manager 168 North 1950 West Salt Lake City, UT 84116 Subject: Submittal of 2006 Monitoring Well Drilling Results Summary and Notification of

Intent to Construct Additional Acidic Plume Extraction Well Dear Rebecca and Doug: In the June 2006 South End TRC, Kennecott Utah Copper Corporation (KUCC) indicated that installation of additional monitoring wells was planned in order to better characterize the contaminant hydrogeology along the south east margin on the Zone A acidic plume, where increasing sulfate concentrations had been observed in several existing monitoring wells. KUCC conducted a drilling program between August and November 2006 and installed five nested monitoring wells in this sector. Attached is a report prepared by KUCC summarizing the drilling and monitoring results from these new monitoring wells. Based on the monitoring results, KUCC has identified an “orphan” of highly-contaminated groundwater southeast of existing extraction well BSG1201. That this contaminated groundwater is orphaned indicates it is likely not within the effective capture zone of BSG1201. Consequently, KUCC intends to install a third acidic-water extraction well. The location and construction details for this new well are indicated in the attached report. The existence of the highly-contaminated orphan does not imminently threaten KUCC’s ability to meet the containment performance standard outlined in the pending Explanation of Significant Differences. Instead, KUCC’s motivation for a prompt and aggressive response is to 1) expedite and optimize the remediation of the aquifer, 2) prevent this water from reporting to the extraction wells B2G1193 and BFG1200, which supply water to the Reverse Osmosis treatment plant, and 3) assure long-term ability to meet the containment requirement.

Letter to Thomas and Bacon February 13, 2007

Page 2 KUCC has commenced engineering design and procurement for the new acid well. Well and pipeline design and materials will be similar to the existing acidic water extraction wells and consistent with the designs described in the 2003 Final Design for Remedial Action. Construction of the pipeline is expected to begin in mid March. The well is to be drilled in May and functional by July 2007. KUCC is planning to equip the new well to produce 900 gpm. Production from BSG1201 will be decreased from 900 gpm to 500 gpm. Production from ECG1146 will remain at 900 gpm. This will result in a net increase of 500 gpm average instantaneous extraction from the acidic plume. KUCC has initiated the process with the Utah Division of Water Rights to secure the necessary water rights to accommodate the increased extraction. Should you have any questions or concerns with regard to this matter, do not hesitate to contact me.

Sincerely, Kelly L. Payne, P.G. Principal Advisor, Closure & Remediation

Monitoring Well Drilling Summary for Kennecott’s South End Groundwater Remedial Area During 2006 Introduction Monitoring well analytical results showed increasing sulfate concentrations from late 2004 and 2005 within and adjacent to the southeast and east portion of the Zone A low pH plume. The results prompted Kennecott Utah Copper (KUCC) to place new monitoring wells in the area east of Highway 111 and southerly from Acid Well #2 (BSG1201). The new monitoring well sites placed within Zone A low pH area were installed to add hydrogeology and geochemistry detail and to evaluate whether an additional acid extraction well should be installed to aid in the containment of the low pH plume. KUCC also replaced two monitoring wells that were abandoned in 2005 due to development activities by Kennecott Land Company. The two monitoring well sites are in the Daybreak area located east of the former South Jordan Evaporation Pond area. A total of seven sites were drilled with mud rotary by Layne Christiansen Drilling in the late summer/fall of 2006. Four of the sites were completed with two wells (double completion) and three sites were completed with three wells (triple completion). Out of the seven sites, five are located in and adjacent to the low pH, Zone A plume area. Prior to the installation of the PVC wells, each borehole was logged for geology and with geophysics. Screen intervals were selected based on the logging to target the most transmissive and most contaminated intervals. Each of the completions included a 20 foot screen interval and each completion was developed using air-lift techniques and sampled. The drilling, logging, and sampling techniques used were consistent with methods listed in KUCC’s Groundwater Characterization and Monitoring Plan (KUCC 2005) and from KUCC’s Remedial Investigation Report, Appendix D and E (KUC 1998). Drill Sites, Well Identifications and Hydrogeology Results The five sites drilled within and adjacent to the low pH plume include: BSG2777, BSG2778, BSG2779, BSG2782 and BSG2783 (Fig 1). Below is summary of the findings for each of the five sites. • Site BSG2777 was drilled one-half mile east and one-quarter mile south of acid

extraction well BSG1201. Well ID Screen Interval

BSG2777 geology included sandy and silty quartzitic gravels with minor volcanic gravels through the total depth of boring (740 ft). Based upon an adjacent monitoring well, ABC05, geology below 720 feet at this site has low transmissivity and is clean. ABC05 was drilled in 1990 using the dual wall reverse circulation method and field

measurements for water conductivity and pH were measured during drilling on 20 foot intervals. Results of the field measurements showed that high conductivity groundwater existed from the top of the water table through at least 600 ft below ground surface. No screen interval was placed in the poor quality zone for ABC05 so BSG2777A and B screens were placed to help bracket the water quality for this area (Section AA-AA’ and BB-BB’). For comparison purposes, the most recent water quality at Acid Well #2 shows sulfate at 10,700 mg/L, pH of 3.45 and TDS of 15,500 mg/L The BSG2777 site is located on the western edge of a northerly trending Plio-Pleistocene fault. This fault or faults is not present on the surface and the fault does not appear to cut the late Pleistocene unsaturated alluvial section. This fault or faults appears to have decreased the lateral transmissivity of the stratigraphic package that is transmitting poor quality water for the general area. However, acidic/high TDS water continues eastward into the thicker principal alluvial aquifer as is indicated by increasing sulfate concentrations in BSG1133B (Section AA-AA’). The thickness of high TDS water at BSG2777, based upon the down hole geophysical logs, specifically from the induction log, is approximately 120 to 160 feet thick with the highest TDS at 550 to 570 feet below ground surface. The water table at this site is 375 feet below ground surface. KUCC’s monitoring well BSG1133B, located one-quarter mile east of BSG2777, shows increasing trends for TDS/sulfate. Based upon gradient and water contour maps from KUCC 2005 Annual Report (KUCC 2005), this same poor quality water at BSG2777A is diluted with cleaner water as it moves eastward into the thicker saturated principle alluvial aquifer. The same hydrogeology picture as seen in Section AA-AA’ can be seen in Section Y-Y’ (KUCC, Appendix I 1998), located one-quarter mile north and parallel to Section AA-AA’. In both sections, the basement rises to the east and then declines basin-ward near monitoring well BSG1119 on Section Y-Y’ and near BSG2777 on Section AA-AA’. KUCC has mapped a northerly trending normal fault located immediately west of BSG1119 and immediately east of BSG2777. • Site BSG2778 was drilled on west edge of Bastian Sink and located three quarters of

a mile due west of site BSG2777. Well ID Screen Interval

At this site, silty volcanic gravel was encountered in a large part of the saturated principle alluvial aquifer with thin interbedded silty quartzitic units. This site is approximately one-quarter mile southwest and upgradient of Acid Well #2. The volcanic gravels are known from previous work to have more neutralizing ability and less permeability than the quartzitic gravels. Screen intervals for BSG2778 were

placed in relatively thin silty quartzitic units in the lower portion of the principal alluvial aquifer. Site BSG1179C, located approximately one-quarter mile due east of BSG2778, showed poor water quality at depth, thus BSG2778A and BSG2778B were placed to test the possible deeper pathway for high TDS water. Based upon the data for the two new wells, the deeper pathway does not exist at the BSG2778 site. The induction log for BSG2778 does show significant contamination from 440 to 550 ft which is above the screen intervals for this site; however, the gamma log and drill cuttings for this interval show significant fine grained sediments with moderate amounts of volcanic gravel. This site helped delineate the southwest edge of the capture area for Acid Well #2 and also helps delineate the southwest margin of acidic plume east of Highway 111. • Site BSG2779 was drilled approximately one-quarter mile south of B2G1193. Well ID Screen Interval


BSG2779A 530-550 7.83 2860 4270 BSG2779B 690-710 8.27 2050 3240 BSG2779C 820-840 8.31 54 459 BSG2779 was drilled to 880 feet and it contained unconfined saturated quartzitic gravels with minor volcanic gravels though the entire borehole. This site is approximately one-quarter mile east of BSG1119 site. BSG1119B was the east most monitoring site showing low pH water (prior to drilling of BSG2777). The high TDS water in the A and B completions is coming from poor quality water that is moving through the relatively tight package of sediment containing the northerly trending fault (see Plan View Acid Plume). Also, the deeper water in principal alluvial aquifer has seen very little of the poor quality water moving from the west. Water quality as based on the A and B completions likely moves north towards B2G1193 and is being diluted. TDS concentrations at B2G1193 are less than 3000 mg/L. B2G1193 has a screen interval of 451 to 1060 ft below ground surface. • Site BSG2782 was drilled approximately one-quarter mile west of site BSG2777. Well ID Screen Interval


BSG2782A 580-600 3.50 26,700 37,000 BSG2782B 680-700 4.40 6400 9270 BSG2782C 810-830 3.59 26,000 36,900 BSG2782 is located half way between BSG2777 and BSG1179 and was drilled to 875 feet. This site was placed to confirm the depth of the highly contaminated water in the stratigraphic package that also contained the highly contaminated water found in BSG2777A and also to check whether the lower stratigraphic unit containing contaminated water in BSG1179C was present at the BSG2782 site. It was also

4

anticipated that an extraction well would need to be installed at or near this site and this site would serve as a pilot well for the future extraction well. As indicated by the water quality listed above, both zones in the principal alluvial aquifer at BSG2782 contain low pH highly contaminated water. The two distinct packages are separated by a silty lithology that contains some volcanic gravel. The BSG2782B screen was placed in this zone and the water quality data shows that it contains less than 25% of the TDS as compared to the A and C screen intervals. Also based upon the stratigraphy and its correlation eastward, it appears that the deeper contaminated package may have less transmissivity than the upper contaminated package because the contamination has not extended eastward as indicated in the findings from the BSG2777 site. • Site BSG2783 was drilled one-quarter mile south of BSG2777. Well ID Screen Interval


BSG2783A 460-480 8.28 151 701 BSG2783B 560-580 4.09 15,500 22,600 BSG2783C 740-760 8.10 610 1340 BSG2783 was drilled to 840 feet and was located to confirm whether the stratigraphic packages located on the southern side of the low pH plume transitioned into volcanic gravels as had been previous identified by KUCC in the 1990s. This site was drilled to better locate where the volcanic gravels become thicker and therefore limit the movement of low pH water. The quartzitic stratigraphic package that was encountered in BSG2777 at 390 to 575 feet was also present at BSG2783, but was thinner and located from 490 to 580 (Cross Section BB-BB’). The screen intervals for BSG2777A and BSG2783B were located where the induction log showed the maximum inflection in the curve, interpreted as the highest concentration of contamination. BSG2783 stratigraphy included significant volcanic gravel units including 425 to 462 feet, 598 to 645 feet and 760 through 840 feet whereas the BSG2777 site contained principally quartzitic gravels through its total depth. The lower quartizitic gravel unit in BSG2783 is located at 645 to 760 feet and contains low TDS water. This same lower quartzitic gravel unit correlates with the lower package of sediments at the BSG2782 site. Replacement Wells Drilled East of the Former South Jordan Evaporation Ponds Two sites were drilled as replacement wells for monitoring wells that were abandoned in 2005 to accommodate Kennecott Land Company’s development activities. Both sites are within the western portion of Zone B. • Site EPG2780 was drilled approximately one-half mile east of the former South

Jordan Evaporation Ponds to replace P254A, P254B, and ABC03. Well ID Screen Interval

EPG2780B 440-460 7.86 52 452 EPG2780 was drilled to 540 feet and encountered coarse quartzitic gravel to 225 feet below ground surface in the upper part of saturation. The remainder of the boring contained abundant silt with one small fine sand interval from 440 to 460 ft. The depth to water was 192.20 feet below the top of casing. The findings of this boring and the water chemistry was comparable to the wells that were replaced. • Site EPG2781 was drilled approximately 300 feet east of the newly built South

Oquirrh Lake. This site was drilled to replace ABC08. Well ID Screen Interval


EPG2781A 260-280 6.04 1950 4250 EPG2781B 440-460 6.13 3160 452 BSG2781 was drilled to a depth of 540 feet. The geology was similar to that logged in ABC08 with the exception that the geology for the lower portion of BSG2781 contained more quartzitic gravel than ABC08. The screen interval in ABC08 was placed at 490 to 500 feet. Based upon the geophysical logs for ABC08 and BSG2781, the screen interval for ABC08 contained more silt than the geology directly above so the BSG2781B screen was placed at 440 to 460 feet. Based upon the findings from EPG2780, it is apparent that the geology at EPG2781 contains a thicker saturated column within the coarse quartzitic gravel and this is likely the reason that the poor water quality found at the EPG2781 is present. The source of this poor quality water is thought to be from the former Evaporation Ponds located adjacent to the site. It also is likely that the groundwater at EPG2781 is somewhat stranded due to the low permeability sediments located east of the site which allow limited movement eastward. Conclusions and Planning Forward

Low pH groundwater containing high concentrations of sulfate were found one-half mile east and one-quarter mile south, down gradient of KUCC’s east most acid extraction well (BSG1201). BSG1201 is not anticipated to be able to capture the poor quality water found in monitoring wells BSG2777B, BSG2782A,B&C and BSG2783B. The new monitoring well sites were drilled on one-quarter mile centers within the existing monitoring well locations and have provided the necessary hydrogeology and geochemistry information to more fully delineate the extent of the groundwater quality. A new acid extraction well, BSG2784, is being planned and will be drilled near the end of the first quarter in 2007. Prior to drilling, a dual containment pipeline will need to be installed so that development water from the new well can be captured and sent to the tailings line. The new well site will be located 140 feet east of the BSG2782 site and will be screened from 490 to 600 feet and from 700 to 850 feet. The upper screen interval at

6

490 to 600 feet in the new extraction well will target the stratigraphic package containing monitoring wells BSG2777A, BSG2782A and BSG2783B. The lower portion of the screen interval at 700 to 850 feet will target the stratigraphic package containing monitoring wells BSG2782C and BSG1179C. Based upon the distribution of the poor quality water as mapped on the cross sections, it is likely that the upper screen interval in the new well will be within a higher transmissity interval than the lower screen interval and it is likely that more water will be extracted from this zone than from the lower zone. Monitoring of water levels and water chemistry over time at the new extraction well and from the monitoring wells will provide the information necessary to assess how the new well is performing and the extent of well capture zone. Optimization of the pumping rates over time will be made according to the monitoring well results.

KUCC has begun the engineering for the new well, pipeline and power. The current plan includes pumping the new acid well at 900 gallons per minute and reducing the production from BSG1201 to 500 gallons per minute from its current rate of 850 gallons per minute. KUCC will need to modify the points of diversion on existing water rights prior to drilling the new well and the increased total production will be contingent on additional water rights being secured.
