The operations at the facility included developing photographs from negatives received from various portrait studios. PCA reportedly utilized the basement of the existing on-site building for storage of photograph developing compounds and solutions, a silver reclamation system and storage of waste water from the photo developing processes conducted at the facility. The facility was closed at the end of 2008 and CPI Corporation (Client and parent company to PCA) is currently in the process of removing equipment from the site building and conducting assessment of potential environmental concerns due to former operations. After removal of equipment and storage tanks from the basement of the building, the Client was concerned about the potential release of silver to subsurface soils resulting from leaks and spills during past facility operations. The poor condition of the floor slab could allow released solutions to migrate and adversely impact the underlying soils. 1.2 Scope of Work Terracon visited the site on June 25, 2009 to obtain samples of subsurface soils from beneath the concrete floor slab. A concrete coring machine was utilized to place a 4-inch diameter hole through the floor slab. A hand auger was advanced to a depth of 3 to 4 feet below the concrete slab through the base course gravels. Soil samples were collected from the hand auger bucket and analyzed for silver. Concrete core and sample locations were selected by the Client. The cores were not patched after the samples were collected at the request of the Client. Two additional soil samples were collected at building exterior locations to compare naturally occurring background concentrations for silver to soil samples collected within the building. 1.3 Standard of Care Terracon’s services were performed in a manner consistent with generally accepted practices of the profession undertaken in similar studies in the same geographical area during the same time period. Terracon makes no warranties, either expressed or implied, regarding the findings, conclusions or recommendations. Please note that Terracon does not warrant the work of laboratories, regulatory agencies or other third parties supplying information used in the preparation of the report.

After completion of the 4-inch diameter concrete cores, a hand auger was advanced to a depth of 3 to 4 feet below the floor slab. Terracon personnel noted the color, odor, and lithological characteristics of the soils beneath the building slab. Soils were not screened for volatile organic compounds (VOCs) since they were not identified as a concern from past operations at the site. Auger refusal was encountered in two of the hand auger borings, requiring an additional two concrete cores to be completed in areas of concern. At the request of the Client, one additional soil boring was completed within the basement area. Two additional hand auger borings were advanced at locations outside the building to establish naturally occurring background levels for silver at the PCA property. Soil samples collected at the PCA Facility Project No. 71087772 July 1, 2009 3 site were placed in laboratory provided bottles for transport to Pace Analytical Services, Inc. of Huntersville, North Carolina. After completion of the soil sampling activities, the concrete floor slab was not patched at the request of the Client. 3.0 LABORATORY ANALYTICAL RESULTS Soil samples collected at the site were analyzed for total silver by EPA Method 6010 and silver by the Toxicity Characteristic Leachate Procedure (TCLP). The following table presents the results of the silver analyses. A copy of the laboratory results is provided in Appendix C.

The NCDENR recognizes TCLP results for waste characterization and disposal activities only. PCA Facility Project No. 71087772 July 1, 2009 4 Total silver concentrations were detected in 8 of the 13 soil samples submitted for laboratory analysis. The results were compared to the North Carolina HWS SSLs and the USEPA Region 9 PRGs for Industrial Sites. The PRG for Industrial Sites is the applicable standard for the site as the facility is not developed as residential and children are not exposed to the subsurface soils. While the detected total silver concentrations are well below the Industrial PRG, the detected levelsl are also below the EPA Region 9 PRG residential standards. The NCHWS SSLs are designed to be the most stringent screening levels because the SSLs are protective of groundwater and are typically established by the lowest laboratory detection limit obtainable. As such, silver was detected in the soils underlying the floor slab at levels that exceeded the NCHWS SSLs. The soil samples analyzed for TCLP silver did not exhibit detectable levels of silver. As such, it appears the potential for silver to leach from soils excavated from beneath the floor slab of the basement would be minimal. Should the Client choose to remove soils impacted by silver from beneath the building for off-site disposal, the materials would not be considered to be a hazardous waste. 4.0 CONCLUSIONS AND RECOMMENDATIONS 4.1 Conclusions Thirteen soil samples were collected from the site during Terracon’s mobilization on June 25, 2009. Of these, 11 samples were collected from the basement area within the building and two were collected from areas outside of the building to establish naturally occurring background levels for silver. Based on the results of the laboratory analyses, total silver was detected in 8 of the 13 samples collected from soils beneath the floor slab. The detected concentrations did not exceed the US EPA Region 9 PRGs for residential or industrial sites designed to be protective of human health. However, the detected concentrations of total silver exceeded the most stringent NC HWS SSL for silver designed to be protective of groundwater. Based on the laboratory analytical results, boring locations 14A and 13B exhibited the highest silver concentrations at 311 and 196 milligrams/kilogram (mg/kg), respectively. The remaining 6 soil samples exhibited much lower detectable concentrations of total silver. Based on the results of the two samples collected outside the building (naturally occurring background levels of silver were below detectable levels), it is Terracon’s opinion that releases of silver have impacted subsurface soils in the area of the basement at relatively low concentrations. The areas exhibiting the highest concentrations of silver in subsurface soils are located beneath a sump in the northern portion of the basement area. Silver was not detected above laboratory detection limits in the TCLP samples. 4.2 Recommendations Since silver has apparently been released to subsurface soils beneath the basement area of the building at levels above North Carolina HWS SSLs, further investigation of the basement area is PCA Facility Project No. 71087772 July 1, 2009 5 warranted at this time. Terracon recommends notifying the NCHWS of the presence of silver above its SSL. It is Terracon’s understanding that the Client is interested in unrestricted soil use for the site due to a potential sale of the facility. Therefore, Terracon recommends the following course of action: • Submittal of the existing laboratory data in report form to the NCHWS as an Initial Site Sampling Plan (ISSP); and • Submittal of planned remedial actions and additional sampling activities attached to the ISSP in the form of an Assessment and Clean-Up Plan (ACP) for approval by the NCHWS prior to beginning additional assessment or remedial activities at the site. Terracon will include the following remedial and assessment tasks as part of the ACP plan to NCHWS: Task 1 Installation of three temporary groundwater monitoring wells in the vicinity of the source area utilizing air rig drilling equipment. An air rig should be utilized to access groundwater through anticipated weathered rock and/or stiff clays. Temporary groundwater monitoring wells will be constructed with pre-packed filter screens to eliminate sediments influx in groundwater. Groundwater samples will be collected from each well and analyzed for total silver by Method 3030C. The top of casing and groundwater elevations for each well will be surveyed to determine a groundwater flow direction at the site. Task 2 Complete a receptor survey in accordance with NCHWS guidelines. The NCHWS specifies that sensitive receptors should be identified within a 1,500-foot radius of the site. The receptor survey will be completed during the monitoring well survey activities. Task 3 Remove the subsurface soils impacted by silver within the basement area of the building for disposal at an off-site facility. After removal of impacted soils, collect and analyze confirmatory soil samples for total silver by EPA Method 6010. Upon receipt of laboratory analytical results confirming silver concentrations are below laboratory detection limits or exhibit concentrations below the SSLs, the excavation will be backfilled with clean fill materials and the basement floor will be replaced with new concrete. Please note that the laboratory analytical results for total silver are currently below the US EPA Region 9 PRG for residential use of 390 mg/kg. In the event sensitive receptors are not identified and silver is not detected above laboratory detection limits in groundwater at the site, it is likely the NCHWS would accept the results of Task 1 and Task 2 as a demonstration that groundwater has not been impacted resulting in a low risk to individuals that may be utilizing groundwater in the vicinity of the site. As such, removal of subsurface soils impacted by silver beneath the basement area may not be required by the NCHWS as part of the ACP or as a requirement of No Further Action status. PCA Facility Project No. 71087772 July 1, 2009 6 Task 4 After completion of the remedial activities as approved by NCHWS, complete and submit a Closure Report to the NCHWS for review. Based on NCHWS Guidance Documents, when a source area has been remediated to appropriate cleanup levels, the NCHWS will issue a letter stating that No Further Action is required. At the request of the Client, Terracon can complete a Change Order and detailed Scope of Work with anticipated costs on a Task by Task basis for the above recommendations.
