Gorrective Action Plan - Soil lnternational Resistive Company, lnc. r Boone, Watauga Co., NC November 21,2012 r Teracon Project No.86127103 l[erratron Summarize the results of soil, groundwater, surface water assessment and free product measurement, indicating the nature and extent of contamination, the estimated rate of migration, and potential for impacting receptors: Laboratory analysis of soil samples reported total petroleum hydrocarbons-diesel range organics (TPHono) at a maximum concentration of 73 milligrams per kilogram (mg/kg) in shallow soils in the Former AST Area. Laboratory analysis of soil samples reported TPHono at a maximum concentration of 1,400 mg/kg in shallow soils in the Surface Spill Area. Laboratory analysis of a groundwater sample (Phase ll ESA) collected in the Former AST Area reported a naphthalene concentration of 9.4 micrograms per liter (pg/L); laboratory analysis of a groundwater sample (Phase ll ESA) collected in the Surface Spill Area reported a 1,1-dichloroethane concentration of 8.4 pg/L. Miscellaneous other semi-volatile organics for which there are no applicable regulatory standard were reported in groundwater samples collected in both areas. Only limited groundwater assessment has been performed in the two areas due to the impending dernolition of the onsite buildings in preparation for site sale and redevelopment; additional groundwater assessment will be performed once dernolition efforts are complete. A separale conective action plan will then be prepared to address groundwater impact, if necessary. lndicate the risk classification (or non-UST petroleum/non-petroleum UST rank) and the criteria for that determinationr The site has been assigned a "High" risk ranking by NC DENR, because shallow soils in both areas contain elevated TPDono concentrations (i.e., greater than 40 mg/kg) and there are active potable wells within a 1,000- foot radius of the site. The concentration (9.4 trg/L) of naphthalene in groundwater in the fuel oil Former AST Area exceeds the NC 2L Standard of 6.0 pg/L, The 1,1-dichloroelhane concentration of 8.4 pg/L reported during the Phase ll ESA in the Surface Spill Area is assumed to be associated with the volatile organic compound (VOC) plume located along the rear of the main plant building; this VOC release is unrelated to the areas under discussion herein and is being managed by the lnactive Hazardous Sites Branch. lndicate the soil, groundwater, and sudace water concentration levels to which contamination must be remediated: Soil in the two areas must be remediated to less than the Soil-toGroundwater Maximum Soil Contaminant Concentrations (MSCCs). Groundwater impaded by releases from the two areas will require remediation to the 2L Standards; this will be addressed in a separate document, if required, based on further groundwater assessment. Surface water has not been sampled but is not suspected to be impacted based upon the apparent limited extent of groundwater impact as a result of the two releases. Present the selecied remedy for soil and groundwater contamination and/or actions to reduce the risk classification (or rank) and briefly state the basis for selection, schedule for implementation, remediation milestones, and cost: Excavation and removal with offsite disposal has been selected as the most appropriate soil remedy based upon the relative cost, ease of implernentability, and both short- and long-term effectiveness. The total cost to excavate and remove impacted soil in the Former AST and Surface Spill Areas is estimated to be approximately $15,000. Soil rernoval is planned subsequent to dernolition of the onsite structures which is expected to be completed in April 2013; it is anticipated that soil rernoval can be completed in approximately one to two weeks. 7. iltResponsive : Resourceful r Reliable Corrective Action Plan - Soil lnternational Resistive Company, lnc. r Boone, Watauga Co., NC November 21,2012 r Tenacon Project No. 86127103 C.

SITE HISTORY AND CHARACTERIZATION llerracon 1. Provide information for AST owners/operators and other responsible parties: The names, addresses, telephone numbers, and dates of ownership/operation of the fuel oil AST and the hydraulic oil ASTs are presented in Table B-2: Site History-UST/AST Owner/Operator and Other Responsible Pafty lnformation (see Section J of this document). The location of the site is illustrated on Figure '1 . 2.

The locations of the two Areas are depicted on Figure 2. There were no previous contents of the fuel oil AST or the hydraulic oil ASTs. A run of 3/&inch diamder piping for the fuel oil AST ran from the AST directly to the humidity steam unit machine. Each hydraulic oil AST was integrated into a separate mold press machine. These tanks have all been removed from the site as part of site decommissioning adivities. The incident number for the site is 95191 . Provide information about petroleum AST systems, petroteum spills, and other non-UST petroleum releases: The locations of the former fuel oil AST and the hydraulic oil ASTs are depicted on Figure 2. Specific details related to the ASTs are presented in Table B-2: Site Histry- ASf System and Other Release lnformation. Provide a comprehensive description of the release: A Phase ll Environmental Site Assessment (ESA) was performed at the site in October 2011 by synTara. Two separate areas, a former fuel oil AST (Former AST Area) and an apparent surface spill location (hydraulic oil ASTs associated with machinery, also referred to herein as "Surface Spill Area") were identified by synTerra in the Phase ll ESA report as having a "potential for contamination to be present" based on either historical operations or the presence of surface staining. Soil and groundwater sampling in these two areas during the Phase ll ESA indicated a release. The estimated quantity and cause of release in each of these two areas is unknown.

Provide a brief description of site characteristics: The site use was formaly utilized by lnternational Resistive Company for industrial purposes but that prooess has been permanently discontinued and the facility is currently being decommissioned in preparation for demolition and site redevelopment. Property to the north is used as commercial retail and residential. Proprty to the east is used as residential. Property to the south is mostly vacant and wooded with some sparse residential development. Property to the west is used for commercial purposes. The site is mostly level, similar to property to the north, east, and west. Property to the southeast and southwest is situated at a higher elevation than the site. Property directly south of the site is significantly higher over a sho( distance (steep slope). The southern and southwestern portions of the site are covered with hardwood trees. The eastern and western portions of the site are covered with grass. A spring originates on the steep slope south of the site and flows onto the site where it enters a culvert. This spring flows through the culve( beneath the southern portion of the plant towards the east where it enters a storm drain box and turns north where it rqnains in a culvert until it flows beneath Greenway Drive and a residential lot where it flows into a stream bed. A second spring originates from property southeast of the site and flows into a culvert on the site and enters the storm drain box discussed above. Two water supply wells are located on the site: DW-1 east of the plant and DW-2 south of the plant. The two wells are located greater than 250 feet from the Former AST Area and the Surface Spill Area. The wells formerly supplied water for use in plant operations and were not used as sources of drinking water. Drinking water for the site was provided by the Town of Boone municipal water system. Municipal water is available in the area and is used by surrounding commercial properties and residential properties. There are nine monitoring wells currenfly located on the site that are used to monitor a VOC plume located on the south side of the plant; this release is being managed by the lnactive Hazardous Sites Branch and is unrelated to the two areas under discussion herein. Surface cover north and east of the plant is asphalt; south and west of the plant is grass. The soil type is mainly sandy clayey silt and sifiy sand. Depth to and nature of bedrock is unknown. Depth to groundwater ranges from three to eleven feet below ground surface based on existing monitoring wells and soil/groundwater assessment activities. Based on the groundwater depths measured in the monitoring wells discussed above, groundwater flow is to the east-northeast across the site.

E. SUMMARY OF SITE ASSESSMENT INFORMATION 1. Summarize site assessment information and any pre-CAP monitoring: Groundwater was en@untered at a depth of approximately 10 feet below ground surface in the Former AST Area and at an approximate depth oI 12 l*l in the Surface Spill Area. Laboratory analysis of soil samples reported TPHono at a maximum concentration of 73 mg/kg in shallow soils in the Former AST Area. Laboratory analysis of soil samples reported TPHono at a maximum concentration of 1,400 mg/kg in shallow soils in the Surface Spill Area. As part of the Phase ll ESA, laboratory analysis of a groundwater sample collected in the Former AST Area reported a naphthalene concentration of 9.4 pg/L; laboratory analysis of a groundwater sample collected in the Surface Spill Area reported a 1,1-dichloroethane ooncentration of 8.4 pg/L.

Describe the geology/hydrogeology of the region and the site: The site owner has closed plant operations and plans to denrolish the onsite buildings within the next six months. Therefore, permanent monitoring wells were not installed during the CSA. Should monitoring wells be needed in these areas, they will be installed onoe denrolition activities are complete. The locations of borings installed in these two areas during the CSA were surveyed by a NC licensed surveyor to ensure the boring locations can be located once dernolition is complete. The site lies within the Blue Ridge Geologic Province of North Carolina. Geology in the area of Boone is generally comprised of massive to well foliated biotite granitic gneiss (Geologic Map of Noilh Carclina; Department of Natural Resources and Community Dwelopment, 1985). Generally rocks are strongily foliated and fradured. The percolation of water downward through the fradures has resulted in the formation of a layer of residual weathered material (saprolite) and soil at the land surface. The saprolite and residual soils typically have high porosities but low hydraulic condudivities; thus, they do not readily transmit groundwater. The saprolite and residuum are considered leaky (semi-pemeable) beds which may store and rechargewater to the undollng bedrock aquifer. Groundwater occurs within the saprolite and residuum between the clay, silt, and sand grains. Groundwater also occurs and flows within the bedrock along secondary features, joints, and planes of weakness. The movernent of groundwater through the saprolite is strongly influenced by topography. Groundwater within the Blue Ridge generally moves from topographically high areas (recharge zones) to topographically low areas with and along stream valleys (discharge areas). The site is situated adjacent to a steep mountain slope to the south. To the north, east, and west, the topography is generally flat. Soils in these areas may be alluvial deposits. Generally, soils encountered in the Former AST Area consist of a dark brown organic topsoil to a depth of 0.5 feet. A light brown fine sandy silt was encountered from 0.5 feet to six feet. A light brown sligtttly clayey silt was encountered from a depth of six feet to eight feet. A light brown line sandy silt was encountered forn a depth of eight feet to 10 feet down to the termination of soil sampling. Generally, soils encountered in the Surface Spill Area consisted of a dark brown organic topsoil to a depth of 0.5 foot. A tan, finetocoarse sand was enountered from 0.5 feet to six feet in boring SSA-1 . A dark gray silty day and sandy day silt was en@untered below the topsoil in borings SSA-2 through SSA-4. An orange-brorn fine sandy silt was en@untered below the dark gray silty clay. Refusal to direct push technoloSy (DPT) equipment was en@untered at 15 feet in SSA-1 and 14.5 feet in SSA-3. Depth to groundwder at the site ranges from three to 11 feet below ground surface based on measurements obtained from site monitoring wells (associated with a difierent release, managed by the IHSB) and limited groundwater assessment performed during the CSA. Based on water lervel measurernents in the above monitoring wells, groundwater flow has historically been documented as occurring to the east-northeast across the site. 4Responsive r Resourceful r Reliable Corrective Action Plan - Soi! lnternational Resistive Company, lnc. x Boone, Watauga Co., NC November 21,2012 N Tenacon Proiect No.86127103 llbrracon 1. Limited groundwater assessment performed in the two areas has indicated that groundwater is either not impacied by the release (Surface Spill Area) or is only slightly impacted (Former AST Area). Based upon the apparent limited extent of soil and groundwater impad, it is considered unlikely that a groundwater contaminant plume originating from these areas would migrate offsite. Examine and evaluate assessment information: Laboratory analysis of soil samples reported TPHono at a maximum concentration of 73 mg/kg in shalloar soils in the Former AST Area. Laboatory analysis of soil samples reported TPHono at a maximum concentration of 1,400 mg/kg in shallow soils in the Surface Spill Area. The area of soil impact in the Former AST Area is estimated to be approximately ten feet by six feet, extending to an approximate estimated depth of three to four feet below ground surface. The area of soil impact in the Surface Spill Area is estimated to be approximately ten feet by five feet, extending to an approximate estimated depth of four feet bdow ground surface. Laboratory analysis of a groundwater sample (Phase ll ESA) collected in the Former AST Area reported a naphthalene concentration of 9.4 pg/L; laboratory analysis of a groundwater sample (Phase ll ESA) colleded in the Surface Spill Area reported a 1,1-dichloroethane concentration of 8.4 pg/L. Miscellaneous other serni- volatile organics for which there are no applicable regulatory standard were reported in groundwate samples collected in both areas. Only limited grcundwater assessment has been performed in the two areas due to the impending demolition of the onsite buildings in preparation for site sale and redevelopment; additional groundwater assessment will be performed after dernolition efforts are complete. The site is dassified as High Risk. Therefore, the applicable soil cleanup levels are the Soil-toGround'water Maximum Soil Contaminant Concentrations (MSCCs). Groundwater deanup levels for the site (if applicable, to be determined following additional assessment) are the NC Groundwater Quality Standards (i.e., NCAC 2L Standards). As mentioned above, the apparent extent of contamination in these areas, both to soil and groundwater, is limited. These areas are also both located near the center of the property. These characteristics indicate a low potential for contaminant migration ofisite or impact to receptors. The site risk ranking could be lowered by remediation of impacted soil and groundwater (if applicable).

State purpose and objectives of the CAP: The purpose of this CAP is to reduce the concentrations of petroleum hydrocarbons in soil. This document !g not intended to address groundwater impact, if any, in the two areas under review; any potential groundwater remediation will be addressed in a separate document, if necessary, following additional groundwater assessment. 3. State the cleanup goals of the CAP: The soil cleanup goals are the Soil-toGroundwater MSCCs, as discussed in Section E.3. G. COMPREHENSIVE EVALUATION OF REMEDIAL ACTIONS 1. Present and comprehensively evaluate remedial ofiions: Remedial Option Evaluation a. Evaluate risk reduction mechanisms: Not Applicable - The site risk ranking cannot be reduced solely by supplying an alternative drinking water source to water supply well users. b. Evaluate excavation as sole remedial process for soil contamination: Soil remediation by excavation is a viable remedial option for the two Areas. This alternative o<hibits both short and long-term effectiveness; is readily implementable; is ost-effective based on the apparent shallow nature and relatively small volume of impacted soil to be removed; is protective of human helth and the environment; and, is expected to garner NC DENR acceptance. c. Evaluate natural attenuation as the sole remedial process for groundwater contamination: Not Applicable - Groundwater assessment is not complete and any potential groundwater rernediation which may be required will be discussed in a separate document. d. Evaluate a minimum of two viable technology-based remedial options for soil and groundwater: Soil Soil Vapor Extraction - Soil vapor extradion (SVE) is an in situ unsaturated (vadose) zone soil remediation technology in which a vacuum is applied to the soil to induce the controlled flow of air and remove volatile and some senri-volatile contaminants from the soil. The gas leaving the soil may be treated to recover or destroy the contaminants, depending on local and state air discharge regulations. Vertical extraction vents are typically used at depths of five feet or greate and have been succesfully applied as deep as 300 feet. Horizontal extraction vents (installed in trenches or horizontal borings) can be used as warranted by contaminant zone geometry, drill rig access, or other sitespecificfadors. For the soil surface, geomembrane @vers are oten placed over soil surface to prevent short circuiting and to increase the radius of influence of the wells. 6Responsive r Resourceful r Reliable Corrective Action PIan - Soil lnternational Resistive Company, lnc. r Boone, Watauga Co., NC November 21,2012 r Terracon Project No.86127103 llerracon Low Permeability Capping - Hard-surface capping works by maintaining a high-strength, low-permeability cover over the contaminated area to stabilize surface soil and reduce infiltration of surface water. The low- permeability layer can be made from either asphalt or concrete. Asphalt usually is selected in favor of concrete because the bitumen binder in asphalt provides some flexibility, making the oover more resistant to cracks that tend to form as a result of temperature cycling and/or differential settlement. A top coat of bitumen or rubberized-bitumen mastic may be applied to further decrease permeability. For a cap applied in a high-traffic area, gravel may be mixed with the mastic to provide a wear resistant surface. The lovv-permeability layer typically is placed on a high-permeability foundation laye. The foundation helps reduce the negative effects of differential settling and allows drainage. Drainage under the low-permeability layer is needed to prs/ent ponding of small amounts of water that may leak throqgh the low-permeability layer or migrate upward from the soil. Ponded water can freeze and o<pand durirq cold weather, causing frost heave damage to the cover. lf gas generation in the waste volume must be controlled, a permeable vent layer can be plaoed on the surface as the first layer of the cap. Vapor extraction by applying a vacuum to the vent layer at points along the edge of the cap allows collection of gas for treatment. Materials and mdhods used to place a hard-surface cap are similar to conventional road paving, but indude modifications to reduce permeability and increase durability of the paving that forms the low- permeability element. For example, an asphalt layer used for capping consists of bitumen mixed with fine and coarse aggregate to give a specified well-graded aggregate mix as in paving. However, an asphalt paving mixture used for capping will require a more tightly controlled particle size distribution and a higher bitumen oontent in comparison to a standard road paving mi*ure. Groundwater Not Applicable - See above For each option evaluated above: 1) Gonsideration of the nature and extent of the contamination at the site: Surface Soill Area - Soil in this area is impacted by petroleum hydrocarbons from a hydraulic oil release. The extent of soil impact is estimated to consist of an area measuring approximately five feet by ten feet, o<tending from surface (or near surface) to a depth of approximately four feet below ground surface. The surface of this area is grassed so contaminants are oeosed to the environment. Fonner AST Area - Soil in this area is impacted by petroleum hydrocarbons from a fud oil release. The extent of soil impact is estimated to consist of an area measuring approximatdy six fed by ten feet, extending from surface (or near surface) to a depth of approximately four feet below ground surface. The surface of this area is grassed so ontaminants are exposed to the environment. Responsive r Resourceful r Reliable Corrective Action Plan - Soil lnternational Resistive Company, lnc. n Boone, Watauga Co., NG November 21,2012 * Terracon Project No.86127103 'llbrraEon Description of each remedia! technology, mechanism, or process: Excavation - This remedy consists of the removal of impacted material from the site and transportation to a permitted offsite treatment and/or disposal facility; in this case, the material will be managed as a non-hazardous waste with disposal likely in a municipal solid waste (Subtitle D) landfill (waste characterization sampling will likely be required by the landfill prior to its acceptance of the material). The volume of soil to be removed will initially be predetermined based upon data generated during the CSA. Performance objectives will be quantified by the collection and analysis of confirmation samples. lf confirmation sampling indicates that additional soil is present above the remedial objectives, a second round of soil excavation will be performed and additional vermcafun samples collected. Once perfonnance objectives have been achieved the excavation will be backfill with uncontaminated soil that is imported from an offsite source. No permitting is anticipated in conjundion with this alternative. Because this ranedy involves the rmtoval of impacted material, there are no operation and maintenance oosts. Low Permeabilitv Cappino - See previous subsection for description of this technology. For application at this site, a small volume of impacted soil would likely require removal in order to properly install the cap; this material would be managed as a non-hazardous waste, as described in the previous alternative. No permitting is anticipated in conjunction with this alternative. Because this ranedy does not involve treatment and/or removal of the impacted soil, the cap must be maintained in perpetuity or until site conditions allow otherwise. Caps must be routinely maintenanced and inspected to insure the integrity of the system is maintained. Soil Vaoor Extraction - See previous subsection for description of this technology. For application at this site, it is anticipated that one to two vertical soil vapor extradion (SVE) wells tttould be installed in or just outside of the impacted area. ln order to for this alternative to funcdion effectively, it would likely need to be installed in conjunction with a low permeability geomernbrane cover to prevent short-circuiting of the air flow. A relatively small volume of impacted soil would require rernoval and management as a non-hazardous waste, as previously described, in order to install the cover and the vapor extraction well(s). A permit to construct and openate the SVE systenr would be required; this would include obtaining a permit (or a permit waiver) fom the NC DENR Division of Air Quality. Routine opaation and maintenance of the SVE systern uould be required to insure optimum performance. Discussion of feasibility and effectlveness of each remedial technology, mechanigrn, or process: Excavation - Excavation with offsite disposal is a commonly employed remedy at similar sites. lt is readily implementable with common construdion equipment, does not require specialized technology and/or knowledge, and is effective at permanently reducing the risk to human health and the environment. lt is anticipated that contaminated soil from this site can be managed as a 2) 3) 8Responsive r Resourcefu! r Reliable Corrective Action Plan - Soil lnternational Resistive Company, lnc. r Boone, Watauga Co., NC November 21,2012 r Terracon Proiect No.86127103 llbrracon non-hazardous waste; therefore, there are a number of proximate treatment and/or disposal facilities that are permitted to accept impacted soil from this site. There are no operation and maintenance (O&M) costs associated with this ranedy. Low Permeabilitv Caooinq - A low permeability cap can be installed using common construction practices and equipment. Although capping is effective at reducing the potential for leaching to groundwater and for preventing direct human contact through dermal exposure, it is not effeclive at reducing the concentration of site contaminants when used as a standalone remedy. Caps and cap integrity must be maintained long term; therefore, land use restrictions must be employed in conjunction with a cap. Land use restrictions associated with a cap may impact site rede\relopment options. Soil Vaoor Extraction - An SVE systern can be installed with commonly available drilling rigs and construction equipment. ln most cases, the vacuum extraction pump and other syatent @mponents are readily available from a number of suppliers. SVE is effective at reducing conlaminant concentrations in situ through either volatilization or biodegradation. Because surface and shallow soils at this site are impacted, SVE would require mupling with another technique such as excavation with the installation of a low permeability geomembrane @ver. ln order to properly design an SVE systern for a given site, a pilot test is often required. As mentioned praniously, SVE systerns require regular O&M in order to insure proper operation. 4) Remedial system operation and maintenance plan for each remedial option: Excavation -There is no O&M schedule associated Wth this remedy. Low Permeabilitv Caooinq - O&M for a low permeability cap typically includes, at a minimum, an annual inspection by a qualified person to assqss the condition of the cap and the need for repair and/or maintenance. Maintenance activities may include re-sealing of the material, repair of cracks, and/or removal of nearby deep-rooted vegetation (sudt as trees). Soil Vaoor Extraction - Regular O&M is essential for the proper performance of an SVE systern. lnitially, it is usually recommended that O&M visits be made by a trained professional on a weekly basis. This schedule can be reduced to monthly or even quartaly, especially if telerndry is integrated into the systern. Periodic site visits will continue to be made throughout the operational life of the systern, however, for routine tasks such as changing filters and belts, adjusting flowrates, and replacing offgas treatment units and/or disposing of accumulated water. Once ontaminant rernoval rates have reached an asymptotic level, system operation may be reduced from full-time to intermittent (or pulsed) to reduce operational costs. 9Responsive r Resourceful r Reliable Corrective Action Plan - Soil lnternational Resistive Company, lnc. r Boone, Watauga Go., NG November 21,2012 r Terracon Project No.86127103 'lferracon Waste treatmenUdisposal plan for each remedial option: Excavation - As previously discussed, it is anticipated that contaminated soil from this site may be managed as a non-hazardous waste with disposal at a Subtitle D landfill. The total volume of soil to be disposed from both areas is estimated to be approximately 25 tons. Low Permeabilitv Caooinq - See above for management of impacted soil generated during cap installation; the total volume of soil to be disposed from both areas is estimated to be less than one ton. No other wastes are anticipated with this alternative. Soil Vaoor Extraction - See above for management of impac'ted soil generated during system installation. The total volume of contaminated soil from this site that would require clisposal is estimated to be less than one ton. lf off-gas treatment is required, it would likely consist of treatment via granular activated carbon (GAC); as the GAC units are expended (i.e., 'spent") they would be replaced with nerrtr units and returned to the manufadurer for regeneration, likely on a semiannual to annual basis. lt may also be necessary to periodically manage accumulated water; this material would require charaderization prior to treatment and disposal, however, at this site it would be anticipated to be managed as a non-hazardous waste. The volume of water to be managed as a result of SVE operation is estimated to be approimately 100-200 gallons per year. Monitoring ptan for each remedial option: Excavation - Monitoring is not required for this alternative. Low Permeabilitv Caooino - Monitoring in the form of visual assessment would be performed on an annual basis. Soil Vapor Extraction - Monitoring of the SVE influent and effluent (post treatment, if applicable) would be performed on a periodic basis (assumed quarterly once systern has undergone startup/shakedown phase) using an Organic Vapor Analyzer (OVA), Toxic Vapor Analper (TVA), or similar field screening dwice. Once per year, an influent sample would be collected for laboratory analysis using Method TO-15 (i.e., volatile organics). Monitoring results would be summarized in an annual monitoring report to be submitted to the NCDENR. Once influent concentrations reach asymptotic levels, soil borings may be advanced into the impaded zone to collect soil quality data; soil samples will be analyzed for VOCs and/or SVOCs using EPA Mdhods 82608 and 827OC, respectively (or approved equivalent methods). 5) 6) Responsive r Resourceful r Reliable 10 Corrective Action Plan - Soil International Resistive Company, lnc. r Boone, Watauga Co., NG November 21,2012 r Terracon Project No.86127103 llbrracon 7) Comprehensive, well-substantiated schedule for each remedial option: As previously discussed, IRC plans to denrolish the onsite structures in order to prepare the site for redevelopment. Therefore, due to the proximity of the two areas under discussion herein to the main plant building, implenrentation of this CAP will not begin until demolition activities are complete. With that fundamental understanding, the following approximate schedules are discussed below and are presented in Table 1. Excavation - Soil excavation is anticipated to take one to two days to oomplete. Confirmation sampling will be expedited so that supplernental excavation efforts may be undertaken if necessary. Once the confirmation sampling results indicate that the remedial objec{ives have been satisfied, the excavations will be bacKilled with offsite material. lmpacted soil will be te-mporarily stored onsite until laboratory data indicate that rernedial objectives are achieved. The entire process is expected to take approximately two to three weeks. Low Permeabilitv Caooino - Preparation of the cap areas is expected to take one day. lnstallation of the cap can begin the following day and is expected to take one to two dap to cornplde. As previously discussed, monitoring in the form of visual assessment will be performed on an annual basis. Soil Vaoor Extraction - lt is anticipated that permitting for an SVE systern muld be complded by the time facility dernolition is complete. The SVE system(s) would be constructed and housed in a prefabricated building which would be delivered and setup onsite; once an order is placed for a system, it is expected to take approximately six weeks for delivery; during that time, the SVE wells, low permeability geomembrane cover, and extradion piping would be installed. Once the system anives onsite, it can be hooked up to the SVE wells in one to two days. Scheduling and completion of systan inspection by the municipality and other parties (e.9., electrical provider) is o<pected to take approximately one week. System startup/shakedown and performance optimization is anticipated to take approximately two to four weeks. O&M adivities will occur on a quarterly basis, or more frequently, if wananted. Monitoring of the system influent (and effluent, as necessary) will be peformed at least one per quarter. Annual reports summary system run time, influenUeffluent concentrations, maintenance issues, and other related adivities will be submitted to the NC DENR for review. Once influent concentrations have reached asymptotic levels, soil samples will be collected for laboratory analysis to verify that remedial objectives have been achisred. lt is anticipated that active SVE treatment will be required for a period of one to two years. Once remedial objectivs have been achieved, the SVE systern will be dismantled and rernoved from the site. All SVE wells will be permanently abandoned in accordance with NC well regulations.

Each project participant shall be certified by a Doctor of Medicine as fit for respirator and semi- permeable/impermeable protective equipment use. All personnel shall have received an environmental physical examination wittrin one year prior to the start of project activities. 4.0 EMPLOYEETRAININGREQUIREMENTS All Tenacon personnel, must have completed 40 hour Hazardous Waste Operations Training and at least three days of supervised fietd activity per the requirements of OSHA 29 CFR 1910.120. ln addition, a current 8-hour annual refresher training certificate will be required for all personnel. Training certificates for all project personnel will be maintained by the Corporate Safgty and Health Manager and/or the SSO at the project command center. Prior to the start of site activities, the SSO will conduct a pre-project safety and health briefing for all project participants. The personnel responsible for project safety and health will be addressed, as will site history, scope of work, site control measures, emergency procedures and site communications. The briefing will address site contaminants, air monitoring protocols, action levels for upgrade/downgrade of personal protective equipment and level of personal protective equipment to be employed for each project task. Safety and health briefings will be presented by the SSO at the start of each work day. ln addition to a general review of the proposed daily activity and safety requirements, the results of previous air monitoring and any procedural changes will be addressed. 5.0 RESPIRATORYPROTECTIONPROGRAM The purpose of the Tenacon respiratory protection program is to prevent personnel exposure to aibome contaminants in excess of established permissible exposure limits/threshold limit values. All respirators employed by Terracon personnel will be NIOSH approved. Cartridges and filters for air purifying respirators will be appropriate for the contaminant(s) of concem. Cartridge/filter selection will be made by the Terracon Corporate Safety and Health Manager. Project perconnel required to wear respiratory protection will be medically cleared for respirator use, trained and successfully fit tested in accordance with OSHA 29 CFR 1 910.134. Personnel required to wear supplied air respirators will demonstrate competence in donning/doffing and inspecting the equipment prior to job assignment. All project tasks requiring the use of supplied air respirators will require properly equipped backup personnel ("buddy system"). At a minimum, air purifying respirator cartridges will be changed daily prior to use. More frequent change of respirator cartridges will be based on the results of site air monitoring. Under no circumstances will air purifying respirators be used in areas deficient in oxygen (<19.5%), in areas classified as immediately dangerous to life and health (IDLH) or in areas where contaminants have not been characterized. Site Safety and Health Plan Former AST and Surface Spill Areas Terracon Project # 86127 103 Page 4 Respirators will be inspected and required fit checks will be performed prior to use, and any necessary repairc will be made before proceeding to the project site. Respirators will be sanitized daily after use. 6.0 SITE HISTORY/SCOPE OF SERVICES Preliminary information obtained from the client indicates that this project site may be contaminated with petroleum hydrocarbons. The personal protective equipment and direct reading air monitoring protocols specified below are designed to prevent perconnel exposure to contramination in excess of permissible exposure limits. 6.1 Scope of Services { Soit/GrcundwaterSampling _ Soil Boring (Drill Rig) _ Remedial System lnstallation { Otner (soil removal) _ Soil Boring (Hand Auger) _ UST Removal (requires tank removal addendum) _ Monitoring Well lnstallation 7.0 HAZARD ASSESSMENT 7.1 Chemical Hazards Soils/groundwater at this project site may be contaminated with petroleum hydrocarbons. Benzene is the most significant health hazard contained in petrcleum blends and typically comprises less than 1% of regular grade gasolines. Specific health hazard information on petroleum compounds and their most healtr-significant volatile fractions are provided below. Additional health-hazard information may be found in the chemica! product information sheets attached to this Plan. Personnel engaged in monitoring well sampling are advised that organic vapors from contaminated groundwater can collect in wells and be displaced by bailers. Perconnel are advised to approach monitoring wells from the upwind side, remove the cap and allow the well to vent momentarily prior to sampling. Keep breathing zone to the upwind side of wells during bailing activities. BEl.lzENE Permissible Exposure Limit 1 ppmOSHAPEL 5 ppm OSHA 10 min Ceiling 0.5 ppm OSHA Action Level Benzene is a central nervous system depressant and an eye and skin initant. Poisoning may cause hemonhages and immunosuppression. A relationship has been discovered between benzene exposure and leukemia. Benzene is regulated as an occupational carcinogen. Acute Site Safety and Health Plan Former AST and Surface Spill Areas Terracon Project # 86127103 Page 5 exposure may cause dizziness, excitation, weakness, headache, giddiness, breathlessness and chest constriction. TOLUENE Permissible Exposure Limit 50 ppm ACGIH TLV (Skin Absorbable) Toluene is an eye, skin and mu@us membrane initant and a central nervous system depressant. Poisoning may affect the liver and kidneys. Prolonged exposure may affect the heart and blood. The ingestion of alcoholic beverages may enhance the toxic effects of toluene. Symptoms of exposure include respiratory tract irritation, headache, dizziness and eye imtation. Toluene may be absorbed to the bloodstream via skin contact. ETHYL BEMENE Permissible Exposure Limit 100 ppm OSHA PEL Ethyl benzene is a skin, eye and mucous membrane initant. lt is moderately toxic by ingestion and slightly toxic by skin absorption. Ethyl benzene is a central nervous system depressant. Poisoning may affect the liver. Symptoms of exposure may include a sense of chest constriction and nervous disorders. Skin contact may result in first and second degrce bums. The odor can be detected at 14O ppm ant irritation occurs at 200 ppm. XYLENE Permissible Exposure Limit 100 ppm OSHA PEL Xylene is a mild eye and mu@us membrane initant, primary skin initant and a central nervous system depressant. lngestion causes severe gastrointestinal upset and creates an aspiration hazard. Chronic inhalation results in symptoms that resemble acute poisoning, but are more severe systemically. GASOLINE Permissible Exposure Limit 300 ppm ACGIH TLV Gasoline is initating to the skin, eyes and mucous membranes. Dermatitis may result from prolonged contact with the liquid. Gasoline acts as a central nervous system depressant. Exposure may cause staggering gait, sluned speech and mental confusion. Gasoline exposute may affect the liver, kidneys and spleen. Absorption of alkyl lead antiknock compounds contained in many gasolines poses an additional health concem, especially wherc there is prolonged skin contact. Site Safety and Health Plan Former AST and Surface Spill Areas Terracon Project # 86127 103 Page 6 DIESEL FUEL (No.2-D) Permissible Exposure Limit 400 ppm OSHA PEL (As petroleum distillates/naphtha) Diesel fuel is a skin and mucous membmne initant and a central nervous system depressant.

FUEL OIL (No. 6) Permissible Exposure Limit 400 ppm OSHA PEL (as petroleum distillates/naphtha) 0.2 mg/m3 OSHA PEL (CoalTar Pitch Volatiles, "PNA'S") Fuel oil No. 6, or "Bunker Fuel", may be initating to the eyes and skin. Poisoning may affect the liver, kidneys and digestive system. This substance is likely to contiain polynuclear aromatic hydrocarbons (PNA's), some of which are considered carcinogenic. PNA's present a skin contact hazard. Avoid skin contact with potentially contaminated site materials. 7.2 Phvsical Hazards Activities to be performed on site may involve drilling equipment and materials. Personne! should be aware that as personal protective equipment increases, dexterity and visibility may be impacted and performing some tasks may be more difficult. Tape all loose protective clothing to avoid entanglement in rotating equipment. Before drilling proceeds, underground utilities must be located and marked. Other drilling safety precautions to be observed during this assessnent include the following: o All personnel working around drill rigs will be familiarized with emergency shutdown procedures and the position of "kill" switches. o No loose fitting clothing, jewelry or unsecured long hair is permitted near the rig. . Keep hands and feet away from all moving parts while drilling is in progress. Shovel auger cuttings with long handled shove!. DO NOf use hands or feet. o Daily inspection of all ropes, cables and moving parts is mandatory. . A first aid kit and fire extinguisher will be immediately available at all times. o All drill crews shall consist of at least two persons. o No drilling is permitted during impeding electrical storms, tornadoes or when rain creates a hazardous work environment. Site Safety and Health Plan Former AST and Surface Spill Areas Terracon Project # 86127 103 PageT o A minimum horizontal and vertical clearance distance of 10 feet must be maintained between the drill rig and overhead power lines; use spotters to help rig operator maneuver the vehicle when near overhead power lines. Other physical hazards which may be present on this project site include: Back injuries due to improper lifting - Use proper lifting techniques. Lift with the legs, not the back. Keep loads close to the body and avoid twisting. Loads heavier than 50 pounds (lbs) require a second person or mechanical device for lifting. Use mechanical devices such as drum dollies, hand trucks, and tool hoists (for lifting augers) to lift or move heavy loads whenever possible. Ergonomic Stress - Lift carefully with load close to body with the legs taking most of the weight. Get help with lifts greater than 40 lbs. When working with a heavy tool or object, keep legs under the load and do not overreach or twist to the side. Reposition body to be more square to the load and work. Push loads, rather than pull, whenever feasible. Do not persist with lifting when the load is too heavy. Use a mechanical lifting aid or have a coworker assist with the lift. Rotate repetitMe tasks to avoid soft-tissue fatigue. Falls From Elevated Surfaces - Protect employees from falling off surfaces that have a side or an edge that is 6 ft or more above a lower level. Provide a safety harness and shock-absorbing lifeline or adequate fall protection where applicable. Employees must wear them when woking 6 ft or higher above the platform or main work deck. lnstall either a guardrail system or fall arrest system that conforms to 29 CFR 1926.502 (d) and is approved by the American National Standards lnstitute. Fire and Explosion - Make ABC fire extinguishers accessible in the work area. Store flammables in Underwrite/s Laboratory and Occupational Safety and Health Administration (OSHA) approved metal safety cans equipped with spark arrestors. Store flammable containers more than 50 ft from possible ignition sources. Keep exhaust equipment powered by internal combustion engines well away from flammables and combustibles. Secure hot work permits/approvals before welding or cutting. Store and use compressed gases in a safe manner. Never refuel equipment (e.9., genenators) while it is in operation or hot enough to ignite fuel vapors. Conspicuously mark operations that pose fire hazards "No Smoking' or "Open Flames." Remove trash, weeds, and unnecessary combustibles from the Exclusion Zone (EZ). Transfer of potentially flammable liquids will be conducted with intrinsically safe pumping equipment. Drums will be bonded and grounded prio_r to transfer of potentially flammable liquids. Vehicles - Obey all site traffic signs and speed limits. Seat belts must be functional and in use during operation of any site vehicles (including rentals). Operator shall regularly inspect the vehicle for defective parts, such as brakes, controls, motor, chassis and drives. Always be aware and stay alert to traffic around the work area. lnclement Weather - The project may be shutdown by the SSO during the following inclement weather conditions: poor visibility; precipitation severe enough to impair safe movement or travel; lightning in the immediate area; steady winds in excess of 40 mph; Site Safety and Health Plan Former AST and Surface Spil! Areas Terracon Project # 86127 103 Page 8 or, other conditions as determined by the SSO or Corporate Safety and Health Manager. Work will resume when the conditions are deemed safe by the SSO. . Noise - Wear hearing protection when speech becomes difficult to understand at a distance of 10 ft and while standing within 20 to 25 ft from heavy equipment, pneumatic power tools, steam cleaners, and other equipment in operation that can generate more than 85 decibels (A-weighted scale) (dBA). . Slips, Trips, and Falls - Clear work area of obstructions and debris before setting up. Alter work areas as necessary to provide a safe, reasonably level area. All walking and working surfaces shall mntinually be inspected and maintained to be free of slip, trip, and fall hazards. Keep platforms, stairs, and immediate work areas clear. Do not allow oil, grease, or excessive mud to accumulate in these arcas. Eliminate slip, trip, and fal! hazards or identify them clearly with caution tape, barricades, or equivalent means. Store loose or light material and debris in designated areas or containers. Secure tools, materials, and equipment subject to displacement or falling. o Traffic Control - lf site activities interrupt the normal flow of pedestrian or vehicular traffic, banicades and waming signs which comply with the Manual on Unifonn Traffic Control Devices and/or State or local ordinances will be erected around affected equipnrent. Safety omnge work vests will be wom by personnel working within 10 feet of any active roadway. All borings or partially completed groundwater monitoring wells will be adequately epvered and/or barricaded if left unattended for any period of time. 8.0 SITE CONTROL An Exclusion Zone, Contaminant Reduction Zone and a Support Zone will be established whenever project activities require Level C or Level B personal protective equipment. Defined access and egress points will be established and personnel will enter only through those points. As permitted by site topography, the area within a 50 foot radius of a drill rig and 100 foot radius of UST removal excavation shall be considered the Exclusion Zone. Only those personnel designated by the Project Manager/SSO are allowed to enter the Exclusion Zone. Where practical, or where their use will prevent public injury, temporary signs or barricade fencing will be established to define the Exclusion Zone. ABSOLUTELY NO SMOKING WILL BE PERMITTED WITHIN THE EXCLUSION OR CONTAMINANT REDUCTION ZONES ON ANY PETROLEUM CONTAMINATED SITE. !f unauthorized personnel attempt to enter the exclusion zone, the SSO will verbally inform the individual(s) to leave the project site. lf unauthorized individuals refuse to leave the Exclusion Zone or are considered in danger or pose danger to project personnel, the SSO will cease project activities (i.e., shut down drill rigs, excavation equipment, etc.) and notify the client representative or the local police of the situation. Site activities will not resume until unauthorized personnel have left the project site. Site Safety and Health Plan Former AST and Surface Spill Areas Terracon Project # 86127 103 Page 9 9.0 AIR MONITORING AND SITE ACTION LEVELS This air monitoring protocol is designed to prevent personnel exposure to airborne contraminants in exoess of established permissible exposure limits. The results of field air monitoring will be used to determine the continued adequacy of initial personal protective equipment. Air monitoring equipment required for petroleum contaminated sites will include the following: r PhotoionizationDetector Task Leader(s) will be knowledgeable in the operation of the photoionization detec*or. A manual on the operation of the PID and the appropriate calibration kit will be mobilized to the project site with the instrument. Photoionization detectorc will be calibrated under field conditions each day prior to use. Task Leaders are instructed to consult the manufacture/s specifications for appropriate calibration gas and calibration techniques. A photoionization detector (PlD) will be used to determine approximate hydrocarbon vapor conentrations in the BREATHING ZONE of site personnel. Continuous breathing zone air monitoring will be conducted during initial phases of intrusive activities (i.e., boring, excavation). lf PID readings are less than 10 ppm, monitoring may be conducted at intervals of 10 minutes. lf initial PID readings exceed 10 ppm, or if hydrocarbon odors become evident upon during auger advancement, continuous breathing zone air monitoring will be conducted.. lf sustained PID readings in the breathing zone exceed 25 ppm, personnel will upgrade to respiratory protection as outlined below. Personnel will remain in air purifying respirators until the photoionization detector readings in the breathing zone have fallen and stabilized below 25 ppm. 9.1 Site Action Levels lnstrument PID Level D/D Mod LevelG Site Evacuation > 300 ppm< 25 ppm > 25 ppm The Action Levels indicated above are for air in the breathing zone and NOT applicable to vapor above containerized soil samples. The Action Levels are established to prevent exposure to airborne petroleum hydrocarbon vapors in excess of established exposurc limits. Although the Action Levels indicated for Site Evacuation are within the protective capacity of the respinator cartridges specified below, personnel will evacuate to the UPWIND side of the site if the continuous breathing zone vapor concentrations exceed these limits. The SSO will contact the Corporate Safety and Health Manager for discussion and re-evaluation of personal protective equipment and air monitoring requirements if airbome contamination exceeds Site Evacuation Action Levels. ln the event that site evacuation is required, a modification of this safety and health plan will be issued with contingencies for combustible gas monitoring and upgrading to Level B personal protective equipment. THIS PLAN IS NOT VALID FOR LEVEL B SITE ACTIVITIES.

Dispose of spent cartridges; wash and rinse respinator . Remove outer gloves . Remove inner gloves Expendable personal protective equipment will be placed in plastic trash bags, sealed and disposed of per client agreement. Decontamination solutions will be containerized or disposed of as ananged by Project Manager. 11.2 Equioment Decontamination Decontamination of equipment will be performed to limit the migration of contaminants off-site. All equipment will be cleaned prior to site entry to remove grease, oil and encrusted soil. Decontamination of large equipment will consist of physically removing gross contamination with shovels, brushes etc. followed by detergent and water high pressure wash with a clean water rinse. The Project Manager is responsible for determining if decontamination solutions must be Site Safety and Health Plan Former AST and Surface Spill Areas Terracon Project # 86127 103 Page 12 containerized. lf so, a decontamination sump or polyethylene sheeting and fluid containers will be mobilized and established in the decontamination area. Deepntamination of hand samplers and similar small equipment will be performed at a designated location within the Contaminant Reduction Zone. Decontamination of such equipment will consist of detergent solution wash and clean water rinse. 12.0 STTECOMMUNTCATTONS Communication between personnelwithin the Exclusion Zone will be via verbal communication or hand signals. Visual contact between members of task teams should be possible throughout the course of project activities. Contact with the SSO will be through direct verbal communication. The following hand signals will be used by personnel wherever rcspiratory protection and/or equipment noise limit verbal communication.

A certificate issued by the American Red Cross, National Safety Council or equivalent will be considered acceptable. For minor injuries, such as cuts, burns, exhaustion, heat cramps, insect stings, etc., the affected employee will be removed to an uncontaminated area. The SSO or other designated employee trained in first aid procedures will administer appropriate first aid. lf the injury wanants additional medicalattention, the affected employee will be properly decontraminated and transported to the nearest hospital or emergency medical facility. For more serious injuries the Site Safety Officer or designee will summon an ambulance to the pQect site. No attempt will be made by Terracon personnelto move the victim, without the aid and/or instructions of qualified medical personnel. Where air monitoring indicates the absence of toxic gases or vapors, the ambulance will be directed to the affected employee. lf site conditions wanant and as time permits, the wheels of the ambulance will be decontiaminated with high pressure wash. The SSO or designee will accompany the ambulance to the medical facility, and provide guidance coneerning additional decontamination which may be required for the injured employee, ambulance or attendants. Whenever an injury occurs on sites with contamination requiring personal protective equipment greater than Level D modified, a minimum of two employees will don appropriate equipment and proceed to the victim. An ambulance will be called immediately. lf the extent of injuries permit, the injured employee will be removed to fresh air. Appropriate first aid will be administered. lf rescuer(s) assess that the victim cannot be removed without a stretcher or other specialized equipment, the victim will be removed at the earliest possible moment by appropriately attired Tenacon personnel with the direction and/or assistance of qualified medical response personnel. The injured employee will be immediately decontaminated and transported to the nearest medicalfacility. A crew member designated by the SSO will inform the ambulance crew of contaminants of con@rn and provide assistance with additional decontamination if required. 13.2 Evacuation and Shutdown Procedures The SSO will establish and notify site personnel of emergency "rally" points. ln the event of a site emergency, personnel will immediately exit the site and assemble at the designated rally point. Evacuation routes will be dependent on site topography and wind conditions. The routes will be selected and presented by the SSO daily prior to site activity. Site Safety and Health Plan Former AST and Surface Spill Areas Terracon Project # 86127 103 Page 14 lf emergency evacuation becomes nec€ssary, the SSO will sound the emergency alarm (e.9. support vehicle horn or compressed air hom). Personnel will safely shutdown all electrical and mechanical equipment and quickly proceed to closest designated rally point. The SSO willthen account for each crew member on site. ln the event that a Terracon employee does not report to the designated rally point within 5 minutes of the evacuation alarm, the SSO will perform an immediate assessment of site conditions. lf site conditions do not pose an immediate hazard to life or health, the SSO will initiate search and rescue efforts utilizing two crew members attired in appropriate personal protective equipment. 14,0 HEAT STRESS 14.1 @ Whenever ambient temperature exceeds 70 degrees F and personal protective equipment requirements are Level D or Level D modified, the following heat stress monitoring and preventive measures will be implemented. At least one gallon of water will be available for each field employee during each day of site activity. The designated Site Safety Officer and one designee will observe personnelfor signs of heat stress (excessive percpiration, flushed skin, nausea, etc.). lf such signs are observed, affected workers will be required to leave the contaminant zone, loosen protective clothing and rest. During the rest period affected personnel will drink at least one 8 oz. glass of cool water. Pulse will be checked at the beginning of the rest period. Personnelwill not return to work until pulse rate is less than 90. 14.2@ ln addition to the above precautions, the following procedures will be implemented whenever the ambient temperature exceed 70 degrees F and personal protective equipment requirements are Level C or above. Ambient temperature will be measured with a dry bulb thermometer and percent cloud cover will be estimated: 1.0 = No Clouds 0.75 = 25% Clouds0.5 = 50o/o Clouds 0.25 = 75% Clouds0.0 = 100o/o Clouds). Calculate the adjusted temperature using the following formula: ADJUSTED TEMPERATURE = 13(% CLOUD COVER) + DRy TEMPERATURE Rest regimens and physiological monitoring (oraltemperature and radial pulse) willbe implemented at frequencies dependent upon adjusted temperature. Site Safety and Health Plan Former AST and Surface Spill Areas Terracon Project # 86127 103 Page 15 Adiusted Temperature 90+ 87.5-90 82.5-87.4 77.5-82.5 70.5-77.4 Rest Period/Monitorino Frequencv After 15 minutes After 30 minutes After 60 minutes After 90 minutes After 120 minutes Employees will return to work only after oral temperature is below 99.7 degrees F and pulse rate < 90. Fluid replacement will be encouraged during each rest period. The use of stimulants and alcoholic beverages in off hours will be discouraged. 15.0 COLD STRESS Percons working outdoors in low temperatures, especially at or below freezing are subiect to cold stress. Exposure to extreme cold for a short time can cause severe injury to the surface of the body or result in profound gener:alized cooling which, in extreme cases, can lead to coma and death. Areas of the body which have high surface area, such as fingers, toes and ears are most susceptible. Protective clothing generally does not provide protection against cold stress. ln many instiances it may increase susceptibility due to excessive perspiration which can rapidly cool the body when exposed to cold, windy conditions. The greatest incremental increase in wind chill occurs when a wind of 5 mph increases to 10 mph. And, because water conducts heat approximately 240 times faster than air, the body will cool rapidly when chemical protective equipment is removed if undergarments are saturated with perspiration. Whenever ambient temperatures are expected to be below freezing, Tenacon personnel will consult the cold strcss section of the Tenacon Safety and Health Policy and Procedures Manual to re-familiarize themselves with signs, symptoms and treatment of cold injuries. Thermal boot, glove and hard hat liners will be mandatory for all personnel conducting field activities in ambient temperatures below freezing. ACKNOWLEDGMENT OF INSTRUCTION All Terracon personnel are required to sign the following acknowledgment of instruction form prior to conducting project activities. This acknowledgment is not a waiver. lt is the primary method used in compiling environmental experience and contaminant exposure records for Terracon personnel.
