HISTORY AND CHARACTERIZATION On November 4, 2003, it was discovered while removing four 3,000-gallon underground storage tanks (USTs) at the former Pisgah. Inn Gas Station that an unknown quantity of gasoline had released into surrounding soils. The release may have resulted from spillage, overfilling, or leakage from the USTs or associated piping: The tanks were permanently closed by removal in November 2003. Approximately 440 gallons of gasoline product, sludge, and water were recovered from within the USTs. A total of 36 cubic yards of contaminated soil was removed and appropriately disposed of (Armstrong 2003). A summary of the former UST system, including information about the UST owner, is presented in Table_ 1. No present or former aboveground storage tanks (ASTs) have been identified at the site. No non -UST or AST releases are known to have occurred at the site. The former Pisgah Inn Gas Station is located within rugged mountain terrain on the Pisgah Ridge in the Blue Ridge Mountains along the Blue Ridge Parkway in Haywood County, North Carolina (Figure 1). The former Pisgah lnn Gas Station is now a gift shop which is part of the Pisgah Inn complex. As indicated in Figure 2, this includes an inn, a restaurant, a campground, and various hiking trails_ The land surrounding the former USTs is within the Pisgah National Forest, and exhibits high topographic relic£ It is used primarily for recreational purposes (Figure 3). No residential communities are located within two miles of the site. Several assessment and corrective action activities have been performed to date at the site, as follows: • UST Closure —Field work, performed in November 2003, included removing four 3,000-gallon USN collecting soil samples (PI -I, PI-2, PL-1 through PL 3, TP_ 1 through TP-14, and SW-1 through SW-5), and excavating and disposing of approximately 36 cubic yards of impacted soil off -site. The associated UST Closure Report was submitted in December 2003 to the UST Section of DENR (Armstrong 2003). • Limited Site Assessment (LSA). Phase I —Field work, performed in spring 2004, included performing a water -well survey, installing one monitoring well (MW-1), collecting groundwater samples from the identified water supply wells (DW-1 and DW 2) and the monitoring well MW- 1, and collecting soil samples from six soil probe holes (SP-1 through SP-6). The monitoring well MW-1 is a flush mount well and screened within the soil overlying the bedrock. The bottom of the well (total depth of 40.5 feet below ground surface [bgs]) is at the top of the bedrock. • Limited Site Assessment (LSA). Phase II —Field work, performed in June 2004, included installing five additional monitoring wells (MW-2 through MW-6) and collecting associated Pifte Ridge ParkwayWr Pisgah 1nnMq orts\CAPtRepnrt ContentsiCAP doc Corrective Action Plan Former Pisgah Inn Gas Station; Haywood County, North Carolina ATTACHMENT 3 -- CAP July 8, 2009 Altamont Environmental, Inc. groundwater samples. All of these monitoring wells are flush mount. Monitoring wells MW-3 and MW-4 are screened within the soil overlying the bedrock; monitoring wells MW 2, MW-5, and MW-6 are set within the bedrock (Figures 4 through 6 and Table 2). The boring logs for these wells are presented in the Limited Site Assessment report (including both Phase I and H work) that was submitted to the LIST Section of DENR in summer 2004 (Armstrong 2004). Groundwater Montt M97-Field work included periodically collecting groundwater samples from the two water -supply wells (DW-1 and DW 2) and selected monitoring wells (MW11, MW-5, and MW-6). No groundwater samples were collected from MW-1 during these monitoring activities because of the continued presence of free product in the well. This monitoring was conducted monthly from October 2005 through September 2006 and quarterly from December 2006 through September 2007. Altamont documented these results in periodic reports (the most recent of which is Altamont September 25, 2007). • CSA—Field work, performed in summer 2008, included collecting eight soil samples (TP-12, SMW-1, SP-1, SP-4, SB-2, S114, SB-6, and SB-8) as well as collecting groundwater samples from four of the six existing monitoring wells (MW 2 through MW-4, and MW-6) and the two water supply wells (DW-1 and DW 2; Altamont 2009). • Free Product Removal —Field work included the installation of a submersible pump in MW-1 in summer 2008 and operation and maintenance of the system which is ongoing. During the Phase I LSA, in April 2004, Armstrong Environmental conducted a receptor survey of the surrounding area within 1,500 feet of the site Two water supply wells (DW-1 and DW-2) were identified northwest (downgradient) of the former UST& These wells provide water for the Pisgah Inn and the adjacent Mount Pisgah Campground. Figure 3 indicates the location of the water supply wells. The water supply wells draw groundwater from the fractured bedrock; according to National Park Service personnel the total depths of DW-I and DW 2 are 400 feet bgs and 200 to 300 feet bgs, respectively. To the best of our knowledge, Pisgah Inn utilizes no municipal water supply systems. According to the North Carolina Source Water Assessment Program (SWAP), DWI and DW-2 are considered part of a Non -Transient Non -Community System, which is defined as a public water system that is not a community system and regularly serves at. least 2S of the same persons six or more months o per year. The site is not located within a Wellhead Protection Area and there are no other known water wells within 1,500 feet of the source area. A springhead of an unnamed stream is located appmxirnately 475 feet west of the campground area and downgtadient of the source area.

According to the DENR, Division of Water Quality, Pisgah Creek is a WS-III Class C stream and is part of the French Broad River Basin. The National Wetland Inventory (NWI) shows that a fieshwater forested shrub wetland lies in the central part of the Pisgah Inn campground area. The approximate outline of this wetland area is shown on Figure 3. The Pisgah inn and Mount Pisgah Campground are recreation facilities for visitors traveling in the area.

The site lies within metamorphosed rocks of the Ashe Metamorphic Suite. Rock types in the area of the site include muscovite-biotite gneiss that is intedayered and gradational with mica schist, minor amphibolite, and hornblende gneiss. The site is located along a major ridge and is covered with a relatively thin veneer of soils. Measured depths to bedrock at the site (based on soil boring refusal depths during the CSA and monitoring -well drilling during the LSA) range from I 1 to 42 feet bgs (Figure 4 and Appendix Q. The soils that were encountered during the UST removal consisted of fill material (sandy silts and well - sorted gravel). Native unsaturated material located below the former tank pit approximately 12 feet bgs are described as light -tan silty sand with cobbles and boulders (Armstrong 2003). Based on the data collected during the LSA and the boring logs from this CSA, the soils overlying the bedrock are predominantly micaceous silty clays and sandy silts. Silty sand soils are also present locally (Figure 4 and Appendix Q. The underlying bedrock:. at the site consists of micaceous schist (Armstrong, 2004). To date, no investigations associated with the release at the former UST system have evaluated the density and orientation of the fractures within the bedrock. 4.2 HYDRoGEOLOGY Based on the topography of the site and water -level measurements obtained during site investigations, groundwater appears to flow across the site from east to west (Figures 5 and 6). The highest water -level elevations are located to the east of the former UST system and the lowest elevations occur in the a o campground, west of the Blue Ridge Parkway. Depths to groundwater measured in the summer of 2008 (August 12, 2008), as part of the CSA, ranged from 14.79 feet below the monitoring well top of casing (TOC) in MW-2 to 38.73 feet below TOC in P:tBtue Ridge ParkwayEMt Pisgah hnARep rtsCCSAtCSA.docx . ATTACHMENT 4 - CSA Comprehensive Site Assessment March 26, 2009 Pisgah Inn Gas Station; Haywood County, North Carolina Ahamont Environmental, Inc. MW-3 (Table 3). Historical depths to groundwater have varied greatly. From December 2006 through August 2008, the depth to the groundwater fluctuated up to I I feet (Table 4) in the monitoring wells. The region experienced exceptional drought conditions during the spring and summer 2008, and this is reflected in the groundwater elevation data. Recent water -level measurements in January 2009 showed water levels at more normal depths. Depths to groundwater measured in the winter 2009 (January 8, 2009) ranged from 8.67 feet below the top of casing (TOC) in monitoring well MW-2 to 27.68 feet below TOC in monitoring well MW-3 (Table 3). The water table or surficial aquifer commonly occurs in the unconsolidated overburden above the bedrock. During the summer of 2008, the water table was measured,just above the top of bedrock or actually within the bedrock (Figure 4). Hydraulic connectivity between the overburden and the bedrock has not been demonstrated on a site -specific basis. However, generally in the Blue Ridge Province of Western North Carolina, groundwater hydraulic connectivity between the overburden and the underlying bedrock does exist. At a location near the top of a ridge, such as the site, commonly the groundwater moves downward from the overburden into the fractures within the bedrock (LeGrand, 2004).

No action is recommended for the soil, because the impacted soils are part of the groundwater smear zone and under the water table (saturated) much of the year. The rationale for these recommended corrective action alternatives is supported by the following statements: • Currently, neither the impacted soil nor groundwater pose a risk of direct exposure to potential human receptors (guests, visitors, and employees of the Pisgah Inn and adjacent campground). This is based on the uppermost zone of impacted soil being approximately 29 feet bgs and the drinking water wells that supply potable water to the Pisgah Inn showing no contamination. • The source of the impacted groundwater is being reduced by the free product removal. • The volume of impacted groundwater is too small to warrant a highly invasive and capital - intensive remedial action. Also the site is used by a high volume of recreators who visit the area near MW-1 (the campground gift store) for a short period of time (up to one hour). The visitors are attracted to Pisgah Inn and the surroundings because of the aesthetic quality of the area. Therefore, installation of aboveground treatment structures (for example, for air sparging and SVE) should be avoided if possible. • Three monitoring wells (MW-04 through MW-06) are strategically located downgradient of the zone of impacted soil and groundwater and upgradient of the drinking water wells. Therefore, they may be used as sentry monitoring wells to indicate whether contamination in the groundwater is migrating toward the drinking water wells. If contamination is identified, then a point source treatment system can be installed and the water quality rigorously monitored to attain drinking water standards. The following provides a description of the free product removal and in situ aerobic bioremediation for the impacted aquifer. 5.2 FREE PRODUCT REMOVAL On August 27, 2008, a pneumatic recovery system was installed in MW-Ito remove free product from the monitoring well. This system operated throughout the fall of 2008, was shut down in late fall 2008, and resumed operating in middle June, 2009. It continues to operate and is scheduled to operate until late November, 2009 when it will be shut down for the winter, then resume operation in the warmer weather. P:'Blue Ridge Parkway\Mt Pisgah Inn\Reports\CAP\Report Contents\CAP.doc 14 ATTACHMENT 3 -- CAP Corrective Action Plan July 8, 2009 Former Pisgah Inn Gas Station; Haywood County, North Carolina Altamont Environmental, Inc. The system includes a submersible pump, a solar -powered controller, a 55-gallon storage drum with an overflow -prevention float switch, a secondary -containment platform, and a compressed -gas canister with a regulator. The recovery system is designed to operate on an intermittent basis. The pump runs for several minutes and pulls the water level down approximately two feet. The pump then remains off for several hours while the water level in the well recovers toward its static level. During these idle periods (periods during which the pump is not operating) free product coalesces in the well. When the pump operates, a mixture of free product and groundwater is removed from the well and stored in the drum for periodic removal and disposal. As of June 18, 2009, approximately 18 gallons of free product and water had been removed from the monitoring well. Altamont is visiting the site on a weekly basis to monitor the system, document how much free product and water have been removed from the well, and to properly dispose of the material as needed. f„�,.,W§«*�sr�,e*-.w,..sw,..c�.,a�r�t,,.:�„„x,+��+,-..�.....:,...r,.c.�.,.x.�..,.,: w,•r :.,,w �+u .y.-.���.;,�, ;•.. 5.3 IN SITU AEROBIC BIOREMEDIATION The corrective action alternative to address the petroleum -impacted zone of the aquifer, anticipated to be a 25-square-foot area immediately downgradient of MW-1 and to be approximately 13 feet thick, is in situ aerobic bioremediation. This bioremediation will be accomplished with an aerobic biostimulant (for example, StimuloxTM manufactured by Carus Chemical Corporation, EHC-00 by Adventus, or equivalent) designed to affect petroleum -related constituents within the impacted aquifer. The additive should significantly stimulate the catabolic activity of the indigenous microflora, thereby accelerating the rate of contaminant removal. The additive will be delivered to the site as a dry powder in drums or 5- gallon pails and mixed with water to create a slurry. The additive and water slurry will be created by mixing the additive with an appropriate amount of water, and injecting the slurry into the subsurface through direct -push technology (DPT) rods, such as GeoProbeTM rods. Given treatment dimensions of 25 feet by 25 feet by 13 feet thick, the estimated treatment volume is 8,125 cubic feet. Altamont requested a proposal and specifications from Adventus, a remediation technology company, for the injection of EHC-Oa', one of their accelerated aerobic bioremediation technology additives designed to address petroleum -impacted groundwater. These specifications, summarized below, are based on applicable analytical and hydrogeological data pertaining to the site. No pilot or bench scale test has been accomplished at the site, and Altamont feels one is not warranted PABlue Ridge Parkway\Mt Pisgah Inn\Reports\CAP\Report Contents\CAP.doc 15 ATTACHMENT 3 -- CAP Corrective Action Plan July 8, 2009 Former Pisgah Inn Gas Station; Haywood County, North Carolina Altamont Environmental, Inc. because of the small volume of the impacted aquifer. The following specifications were provided by Adventus: • EHC-O* application rate (concentration in slurry) is 20% • Total mass of EHC-000 required is 1,500 pounds (Ibs) • Total volume of water required is 710 gallons • Approximate volume of slurry to inject is 890 gallons Ptictt► tmp�etniing t�fvlwtng iujectit groccctts, n>(k ill be :. performed at the site. This sampling event will mimic the post -implementation groundwater monitoring events, described below. The slurry will be pressure -injected into ten injection points spaced approximately eight feet apart. The approximate locations of these injection points are shown on Figure 6. Approximately 150 pounds (Ibs) of EHC-00 and 90 gallons of slurry will be injected at each injection point. The injection points will be the stainless steel rods with an expendable point of an appropriate DPT rig. The bottom of the rods will be in the upper part of the impacted groundwater zone, approximately 12 feet bgs. If excessive back pressure builds up during injection, then the slurry mixture will be thinned to decrease the viscosity of the slurry. This will increase the volume of slurry injected into the subsurface. Upon completion of the slurry injection and withdrawal of the DPT rods, the borehole will be abandoned as appropriate, for instance using a bentonite hole plug. Cement grout should be avoided because it is possible that it would be displaced by subsequent injection of the slurry at nearby points. We anticipate one injection event. The groundwater quality will then be monitored to evaluate the effectiveness of the corrective alternative and to monitor natural attenuation processes. Groundwater samples will be collected from four monitoring wells, MW-1, MW-04, MW-05, and MW-06 approximately x ' " ' ' and quarterly thereafter for the first year. •t " Each groundwater sample will be submitted to an analytical laboratory certified in the State of North Carolina for analyses of volatile organic compounds (VOCs) using US Environmental Protection Agency (EPA) Method 8260, Massachusetts Department of Environmental Protection (MADEP) volatile petroleum hydrocarbons (VPH), and MADEP extractable petroleum hydrocarbons (EPH).

This proposal details the specificaitons for the comparable product OBC by Redox Tech. RE: Former Pisgah Inn Gas Station Mile Post 408 Blue Ridge Parkway, Haywood County, North Carolina Dear Judd Mahan: Redox Tech is pleased to provide the following cost estimate to provide OBC® to help remediate the petroleum contaminated site in Haywood County, North Carolina. We propose using injections of our OB& product in the contaminated area. The mixture in Oxygen BioChemo (OBC) supports a two -fold mechanism for destroying the contaminants of concern, delivering one of the strongest chemical oxidants for short term ISCO (sulfate radicals from catalyzed persulfate), as well as delivering electron acceptors (oxygen and sulfate) for longer -term biological oxidation. OBC employs a mixture of calcium peroxide and sodium persulfate that provides significantly more oxygen per pound than other calcium peroxide based products. OBC is also generally less expensive than these products. OBC provides three modes of oxidation. The first is aggressive chemical oxidation from activated persulfate and calcium peroxide, the second is enhanced aerobic biodegradation from the long term oxygen release of calcium peroxide, and the third is anaerobic biological oxidation as sulfate is used as an electron acceptor. These three modes of oxidation provide a powerful and persistent treatment of contaminated soil and groundwater. Information on OBC can be found on our website www.redox-tech.com. We assumed that the treatment area is approximately 625 square feet and 13 feet thick. We assumed that injections of OBC would be performed through Geoprobe rods at multiple depths. We assumed a total of approximately 760 gallons of OBC solution (1500 lbs of OBC or approximately 2 lbs OBC per gallon) will be injected in a total of 8 Geoprobe injection locations. To develop our costs we assumed that the total oxidant demand (TOD) of the soil at the site was approximately 2 g/kg. Total oxidant demand testing on soil samples will provide a better estimate of the TOD and is recommended to determine the mass of oxidant required. Typical injections of OBC through Geoprobe rods are conducted at injection pressures between 20 psi and 200 psi and at flow rates between 1 and 20 gpm. We assumed others 200 QUADE DRIVE, CARY, NC 27513 TEL 919.678.0140 FAX 919.678.0150 WWW.REDOX-TECH.COM E-MAIL: ROSSABI@REDOX-TECH.COM 4/29/2010 Mountain Environmental Group Waynesville, NC Page 2 of 2 would complete the injection and Redox Tech will supply 1500 lbs of OBC. The price for OBC is $3 per pound plus shipping and tax. We assumed that delivery to your office in Canton, NC will cost $200 and NC tax is 7.75%. The total cost for this proposal is $5,064. The MSDS for OBC is attached. Thank you for the opportunity to provide you with this estimate. We are looking forward to hearing back from you.

Redox Tech, LLC Providing Innovative Soil and Water Solutions Oxygen BioChem (OBCym Recent applications of in situ chemical oxidation (ISCO) have shown that ISCO can be a cost-effective remedial strategy for organic contaminants in groundwater and soil. The application of ISCO to contaminated source areas usually results in an immediate benefit to groundwater in the area. In addition, further contaminant flux can be reduced or eliminated mitigating further contaminant plume issues. Redox Tech has recently formulated a mixture of sodium persulfate and calcium peroxide that can be employed for ISCO applications using FMC's patent -pending KlozurTm activation chemistry. The mixture in OBC supports a two -fold mechanism for treating contaminants of concern. OBC delivers one of the strongest chemical oxidants for short term ISCO, and also provides electron acceptors (oxygen and sulfate) for longer -term biological oxidation. Sodium persulfate has emerged recently as an important oxidant for in situ remediation of volatile and semi -volatile organic compounds. Persulfate is the strongest oxidant within the peroxygen family, with an electromotive force of 2.12 volts. As illustrated below, the direct oxidation half -cell reaction for persulfate involves a two -electron transfer: 2 S2082- + 2 H++ 2e -> 2HSO4 However in most cases, rapid destruction of the contaminant of concern requires that the persulfate be activated in order to generate sulfate radicals. Sulfate radicals are powerful oxidizing agents, with an oxidation potential of 2.6 volts. Klozur activated persulfate is catalyzed with the peroxide and base provide by the calcium peroxide S2082-+ calcium peroxide activator -* 2SO4' Activated persulfate can remain available in the subsurface for months providing an unrivaled combination of power and stability. The calcium peroxide provides several benefits. First, it imparts the alkalinity and peroxide needed to activate the persulfate using FMC's Klozufrm activation chemistry. Second, when mixed with water it provides a long-term slow release source of hydrogen peroxide and calcium hydroxide. CaO2 + 2 H2O 4 Ca(OH)2 + H2O2 The hydrogen peroxide that is slowly formed decomposes to oxygen and water, providing an extended oxygen source for subsequent bioremediation of petroleum hydrocarbons. The resultant calcium hydroxide (hydrated lime) that is produced serves several purposes. First of all, it increases the total dissolved ion concentration, which makes the solution less likely to leach metals from the soil into the groundwater. Secondly, the calcium from the 200 QUADE DRIVE, CARY NC 27513 TEL 919.678.0140 FAX 919.678.0150 WWW.REDOX-TECH.COM E-MAIL: HASELOW@REDOX-TECH.COM Providing Innovative Soil and Water Solutions hydrated lime will precipitate the sulfate that is produced during the consumption of the persulfate. The calcium sulfate (gypsum) precipitation helps to reduce sulfate groundwater concentrations, which may impact the secondary drinking water standard of 250 ppm. The mixture in OBC® provides chemical oxidation as well as electron acceptors (oxygen and sulfate) for longer term biological oxidation. The predominant short-term reaction is chemical oxidation, while the longer -term remediation process is biological oxidation. OBC® has the advantages over more traditional oxygen compounds used for bioremediation in that is works on a broader range of contaminants. Table 1. Contaminants Treated by Oxygen BioChem (OBC)® CONTAMNANTS TREATED BTEX 1,4-dioxane MTBE PCBs PAHs Pentachloro henol Chlorinated Alkenes Chlorinated Alkanes Table 2 summarizes the advantages of OBCO over other oxygenating compounds. OBC® works on a wider range of contaminants than other oxygenates because provides chemical oxidation and electron acceptors for bioremediation. The amount of oxygen in OBC® assumes that all of the oxygen in the sulfate is consumed through sulfate reduction processes. Table 2.

Both products are on the list of NCDENR-approved remediation additives. • Injection is currently scheduled for June 1&2, or as soon thereafter as possible based on UIC permit approval. • OBC®will be delivered to the site in powder form in 30-gallon drums. Mixing with water will take place on site in a 250-gallon polyethylene tank. Approximately 2 lbs of OBC will be mixed per gallon of water. • Eight to ten injection points will be utilized. A direct -push unit will be used to advance probe rods to the required depth of 32 feet below ground surface. Injection will take place through the direct -push rods. • Slurry will be pumped from the poly tank with a Yamada diaphragm pump powered by a Honda air compressor. Injection pressure will be controlled by a pressure regulator on the air compressor. Injection pressure will be monitored by a pressure gauge on the injection tether mounted between the diaphragm pump and the top of the direct -push tool string. If excessive back pressure builds up during injection, then the slurry mixture will be thinned to decrease the viscosity of the slurry. This would increase the volume of slurry injected into the subsurface. • Approximately 760 gallons of slurry is planned to be injected over 8 to 10 injection points.

The application of ISCO to contaminated source areas usually results in an immediate benefit to groundwater in the area. In addition, further contaminant flux can be reduced or eliminated mitigating further contaminant plume issues. Redox Tech has recently formulated a mixture of -sod um.persulfate-andmlcitfmpttU)dde-hat,can-bee eemployed for ISCO applications using FMC's patent -pending Iflozufm activation h istry. The mixture in OBC supports a two -fold mechanism for treating contaminants of concern. OBC delivers one of the strongest chemical oxidants for short term ISCO, and also provides electron acceptors (oxygen and sulfate) for longer -term biological oxidation. Sodium persulfate has emerged recently as an important oxidant for in situ remediation of volatile and semi -volatile organic compounds. Persulfate is the strongest oxidant within the peroxygen family, with an electromotive force of 2.12 volts. As illustrated below, the direct oxidation half -cell reaction for persulfaw involves a two -electron transfer: 2 %0. + 2 W +2e --3 2HS0j However in most cases, rapid destruction of the contaminant of concern requires that the persulfate be activated in order to generate sulfate radicals. Sulfate radicals are powerful oxidizing agents, with an oxidation potential of 2.6 volts. Klozur activated persulfate is catalyzed with the peroxide and base provide by the calcium peroxide S20a + calcium peroxide activator —* 2SO4' Activated persulfate can remain available in the subsurface for months providing an unrivaled combination of power and stability. The calcium peroxide provides several benefits. First, it imparts the alkalinity and peroxide needed to activate the persulfate using FMC's Klozufm activation chemistry. Second, when mixed with water it provides a long-term slow release source of hydrogen peroxide and calcium hydroxide. Ca% + 2 HZO 4 Ca(OH)z + H2O2 The hydrogen peroxide that is slowly formed decomposes to oxygen and water, providing an extended oxygen source for subsequent bioremediation of petroleum hydrocarbons. The resultant calcium hydroxide (hydrated lime) that is produced serves several purposes. First of all, it increases the total dissolved ion concentration, which makes the solution less likely to leach metals from the soil into the groundwater. Secondly, the calcium from the 200 QUADE DRtv1:, CARY NC 27513 TEL 919 678.0140 FAX 919.678.0150 WWWYJMOX TECH.COM E MAIU HASELOW@REDOX TECH COM Providing Innovative Soil and Water Solutions hydrated lime will precipitate the sulfate that is produced during the consumption of the persulfate. The calcium sulfate (gypsum) precipitation helps to reduce sulfate groundwater concentrations, which may impact the secondary drinking water standard of 250 ppm. The mixture in OBCO provides chemical oxidation as well as electron acceptors (oxygen and sulfate) for longer term biological oxidation. The predominant short-term reaction is chemical oxidation, while the longer -term remediation process is biological oxidation. OBCO has the . advantages over more traditional oxygen compounds used for bioremediation in that is works on a broader range of contaminants. Table 1. Contaminants Treated by Oxygen BioChem (OBC)® CONTAIVIMANTS TREATED BTEX 1,4-dioxane MTBE PCBs PAHs Pentachloro henol Chlorinated Alkenes Chlorinated Alkanes Table 2 summarizes the advantages of OBCO over other oxygenating compounds. OBCO works on a wider range of contaminants than other oxygenates because provides chemical oxidation and electron acceptors for bioremediation. The amount of oxygen in OBCO assumes that all of the oxygen in the sulfate is consumed through sulfate reduction processes. Table 2.

PRODUCT AND COMPANY IDENTIFICATION PRODUCT NAME: Oxygen BioChem (OBC)® GENERAL USE: For chemical oxidation and aerobic biorem6diation, petroleum hydrocarbon remediation, creosote remediation and partially halogenated hydrocarbon remediation. MANUFACTURER EMERGENCY TELEPHONE NUMBERS FMC CORPORATION (303) 595-9048 (Medical - U.S. - Call Collect) FMC Peroxygens 1735 Market Street For leak, fire, spill, or accident emergencies, call: Philadelphia, PA 19103 (800) 424-9300 (CHEMTREC - U.S.A. & Canada) (215) 299-6000 (General Information) 2. HAZARDS IDENTIFICATION EMERGENCY OVERVIEW: • Odorless, off-white fine granular solid (may have separation or noticeable two-tone appearance). • Oxidizer. • Contact with combustibles may cause fire. • Decomposes in storage under conditions of moisture (water/water vapor) and/or excessive heat causing release of oxides of sulfur and oxygen that supports combustion. Decomposition could form a high temperature melt. See Section 10 ("Stability and Reactivity"). • Deluge container with water at safe distance or in protected area. • May be severely irritating to the eyes. POTENTIAL HEALTH EFFECTS: Airborne dust may be irritating to eyes, nose, lungs, throat and skin upon contact. Exposure to high levels of dust may cause difficulty in breathing in sensitive persons. No significant long term inhalation hazard; irritation usually subsides after exposure ceases. Page 1 of 10 Oxygen BioChem (OBC)® (F18-44-8) Date: 04/30/2006 3.

FIRST AID MEASURES EYES: Immediately flush with water for at least 15 minutes, lifting the upper and lower eyelids intermittently. See a medical doctor or ophthalmologist immediately. SKIN: Wash with plenty of soap and water. Get medical attention if irritation occurs and persists. INGESTION: Rinse mouth with water. Dilute by giving 1 or 2 glasses of water. Do not induce vomiting. Never give anything by mouth to an unconscious person. See a medical doctor immediately. INHALATION: Remove to fresh air. If breathing difficulty or discomfort occurs and persists, obtain medical attention. NOTES TO MEDICAL DOCTOR: Modest irritation is the only expected effect. No serious consequences are expected, except perhaps in the case of direct eye contact. Contaminated external surfaces should be flooded with water, and direct eye contact deserves ophthalmologic evaluation. If ingested, gastrointestinal irritation but not caustic burns are to be expected; dilution with water indicated as may be gastric evacuation via emesis or lavage if large doses or severe irritation is evident. Demulcents should be helpful. No systemic effects are expected though human toxicity data is sparse. 5. FIRE FIGHTING MEASURES EXTINGUISHING MEDIA: Deluge with plenty of water. FIRE / EXPLOSION HAZARDS: Product is non-combustible. Under fire conditions, may decompose and release oxygen gas, which may intensify fire. Presence of water accelerates decomposition. Mixtures with polysulfide polymers may ignite. FIRE FIGHTING PROCEDURES: Use flooding quantities of water. Use water spray to keep fire exposed containers cool. Do not use carbon dioxide or other gas filled fire extinguishers; they will have no effect on decomposition. Wear full protective clothing and self-contained breathing apparatus.

These chemicals are proposed for use at a Duracell battery manufacturing site contaminated with chlorinated hydrocarbons, petroleum hydrocarbons, acetone, and carbon tetrachloride. This review is provided as supplemental information to that provided to APS in September 2003 by DPH regarding the use of hydrogen peroxide and iron-EDTA activators with sodium persulfate. The information provided to DPH indicates that calcium peroxide will be used at a proportion of 20% calcium peroxide and 80% sodium persulfate. This mixture is diluted to 30%, resulting in approximately 6% calcium peroxide and. 24% sodium persulfate in 70% water. The information also states that sodium hydroxide will be used at 1 to 5% with 30% sodium persulfate. North Carolina Public Health C Working For a heakhy Ever Everysafer Noah Carolina Everywhere.

NC DPH also recommends that transport of these chemicals off -site be controlled to prevent potential human or ecological impacts. Access to the area of application should be limited to workers applying the product. In order to minimize exposure to unprotected individuals, measures should be taken to prevent access to the area of application. SODIUM PERSULFATE HEALTH RISK INFORMATION: Formula: Na2S203 CASN: 7775-27-1 Synonyms: Sodium peroxydisulfate, Sodium persulfate Classification: strong oxidant Sodium persulfate is a strong oxidant and reacts with combustible and reducing materials. Sodium persulfate decomposes on heating producing toxic and corrosive fumes including sulfur oxides. It reacts violently with powdered metals and strong bases. In solution in water it is a weak acid. Sodium persulfate becomes unstable when exposed to heat, moisture and/or contamination. It is incompatible with acids, alkalis, halides (fluorides, chlorides, bromides and iodides), combustible materials, most metals and heavy metals, oxidizable materials, other oxidizers, reducing agents, cleaners, and organic or carbon containing compounds. Oxidizing chemicals, including sodium persulfate, should not be stored or directly mixed with combustible material (such as fuels, papers or solvents) or reducing agents (such as metals or sulfites). Contact with incompatible materials can result in a material decomposition or other uncontrolled reactions. Oxidizing chemicals may react energetically with combustible materials or reducing agents and also release oxygen and heat during decomposition that could help support a fire. Some oxidizing agents are incompatible with one another. Decomposing persulfates will evolve large volumes of gas and/or vapor, can accelerate exponentially with heat generation, and create significant and hazardous pressures if contained and not properly controlled or mitigated. Use with alcohols in the presence of water has been demonstrated to generate conditions that require rigorous adherence to process safety methods and standards to prevent escalation to an uncontrolled reaction. Potential health effects: The primary route of toxicity is through direct inhalation of airborne dust or mist, or direct contact. Airborne persulfate dust may be irritating to eyes, nose, lungs, throat and skin upon contact. Dust dispersion should be controlled. Sodium persulfate in identified as a strong oxidizer and an irritant. Inhalation of dust may cause asthma -like reactions. Acute (short-term) health effects that may occur immediately or shortly after exposure include severe skin and eye irritation and bums. Breathing sodium persulfate can irritate the nose, throat and lungs, causing coughing, wheezing and/or shortness of breath. Long-term (chronic) or repeated exposure may cause a skin allergy or dermatitis. If allergy develops, very low future exposure can cause itching and a skin rash. An asthma -like allergy may also result from long-term or repeated inhalation exposures with future exposure potentially causing asthma attacks with shortness of +� DMMenY U Location: 5505 Six Forks Rd., 2nd Floor, Room 1-2-DI • Raleigh, N.C. 27609 An Equal Opportunity Employer \, Page 3 of 9. breath, wheezing, cough, and/or chest tightness. General allergic reactions, like urticaria (hives) or shock, may occur. Sodium persulfate has not been tested for its ability to cause cancer or reproductive effects. Evidence of exposure includes: Inhalation: cough, labored breathing, sore throat, wheezing Skin: redness, pain Eyes: redness, pain Ingestion: diarrhea, nausea, sore throat, vomiting 'Recommended personal protective equipment (PPE): Prevent release of dust into the work environment with room ventilation. All persons working with sodium persulfate should use appropriate PPE, including: Eves and face: Use cup type chemical goggles. Full face shield may be used. Respiratory: Use approved dust respirator when airborne dust is expected. A NIOSH 100 HEPA tight -fitting half -face unit is recommended (with fit testing). Protective clothing: Normal work clothes. Rubber or neoprene footwear. Gloves: Rubber or neoprene gloves. Thoroughly wash the outside of gloves with soap and water prior to removal. Inspect regularly for leaks. First Aid: Eye contact: Immediately flush with large amounts of water for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. Skin Contact: Quickly remove contaminated clothing. Immediately wash contaminated skin with large amounts of soap and water. Breathing: Remove the person from exposure. Begin rescue breathing (using universal precautions) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. Additional safety recommendations: Prevent release of dust into the work environment with room ventilation. Workers whose clothing has been contaminated with sodium persulfate should change into clean clothing promptly. On skin contact immediately wash or shower to remove the chemical. Remove contaminated clothing immediately and wash before reuse.

CALCIUM PEROXIDE HEALTH RISK INFORMATION: Formula: Ca02 CASN: 1305-79-9 Synonyms: calcium dioxide, calcium superoxide, Calper, Calper G Classification: oxidizer Calcium. peroxide is an oxidizer, thus contact with combustible materials (paper, cotton, organics, leather, reducing agents, and other oxidizers) should be avoided. Calcium peroxide is not flammable but will contribute oxygen to feed a fire. Contamination, heat, and humid conditions will enhance and accelerate decomposition. Decomposition is endothermic, unlike most oxidizers. Store calcium peroxide in a clean, dry place. Do not expose to heat sources or high humidity. Store away from combustible materials. Keep containers closed when not in use. Dilute spills with water. Potential health effects: Contact can severely irritate and burn the skin and eyes with possible eye damage -Breathing calcium peroxide can irritate the nose, throat and lungs causing coughing, wheezing and/or shortness of breath. Harmful if swallowed. The following acute (short-term) health effects may occur immediately or shortly after exposure. Contact can severely irritate and burn the skin and eyes with possible eye damage. Breathing calcium peroxide can irritate the nose, throat and lungs causing coughing, wheezing and/or shortness of breath. Chronic (long-term) health effects can occur at some time after exposure and can last for months or years and include lung . irritation. Repeated exposure may cause bronchitis with. cough, phlegm, and/or shortness of breadth. Calcium peroxide has not been tested for its ability to cause cancer or reproductive effects. Calcium peroxide should be handled in well ventilated, dust controlled areas. When handling large quantities, use a dust mask, goggles, and gloves. Evidence of exposure includes: Inhalation: nose and throat irritation Skin: irritation Eyes: irritation Ingestion: irritation of mouth and stomach Recommended personal protective equipment (PPE): Avoid skin contact with calcium peroxide. Eyes and face: Wear chemical safety goggles. Wear a face shield along with goggles when working with corrosive, highly irritating or toxic substances. ��Olr4ioo' .

SODIUM HYDROXIDE HEALTH RISK INFORAMTION: Formula: NaOH CASN: 1310-73-2 Synonyms: Caustic soda, Lye, Soda lye, Sodium hydrate Classification: alkaline, corrosive Y� pivlUo� 0," Location: 5505 Six Forks Rd., 2"d Floor, Room 1-2-DI •Raleigh, N.C.27609 An Equal Opportunity Employer Page 6 of 9 Sodium hydroxide is classified as a corrosive material. Sodium hydroxide is incompatible with water, acids, flammable liquids, organic halogens, organic peroxides, metals such as aluminum, tin, zinc, or nitromethane. It is corrosive to metals. Keep this compound separated from acids, easily ignitable materials, explosives, metals, organic peroxides, and water or any moisture. Sodium hydroxide will react with water to release heat and contact with aluminum, tin, lead and zinc will release flammable and explosive hydrogen gas. Contact with nitromethane and other nitro compounds may result in the formation of shock -sensitive or -explosive salts. Contact with moisture or water may generate sufficient heat to ignite combustible substances. Potential health effects: Sodium hydroxide is a corrosive irritant of the skin, eyes, and mucous membranes. Sodium hydroxide both in solid and in solution has a markedly corrosive action upon all body tissues causing burns and frequently deep maceration, with ultimate scarring. Inhalation of the dust or concentrated mist can cause damage to the upper respiratory tract and to lung tissue, depending upon the severity of the exposure. Effects of inhalation may vary from mild irritation of the mucous membranes at 2 mg/m3 to severe pneumonitis at higher airborne concentrations. Inhalation of alkaline vapors can produce upper airway edema, respiratory failure, wheezing, pulmonary edema, and pneumonitis. Exposure to the dust or mist may cause pain, redness, irritation or full thickness burns. Contact with the eyes causes disintegration and sloughing -of conjunctival and corneal epithelium, corneal opacification (renders the cornea opaque), marked edema, and ulceration. Permanent visual loss may occur. After 7 to 13 days, either gradual recovery begins, or there is progression of ulceration and corneal opacification. On the skin, solutions of 25 to 50% sodium hydroxide cause a sensation of irritation within about 3 minutes; with 4% solutions, irritation does not develop for several hours. If it is not'removed. from the skin, severe burns with deep ulceration may occur. Produces severe abdominal pain, corrosion of the lips, mouth, tongue, esophagus, and pharynx, and the vomiting of large pieces of mucoua. It can cause perforation and scarring. Glottic edema and upper airway obstruction may occur following ingestion. Cases of squamous cell carcinoma of the esophagus have occurred with latent periods of 12 to 42 years after ingestion. These cancers were the sequelae of tissue destruction and possible scar formation, rather than due to a direct carcinogenic action of sodium hydroxide itself. The greatest industrial hazard is rapid tissue destruction of eyes or skin upon contact with either the solid or concentrated solutions. Acute (short-term exposure) health effects which may occur immediately or shortly after exposure include with contact severe irritation and burning the skin and eyes with possible eye damage or clouding of the eyes with loss of vision. Breathing sodium hydroxide can irritate the mouth, nose and throat. Breathing can also irritate the lungs causing coughing and/or shortness of breath. Higher exposures can cause a build-up of fluid in the lungs (pulmonary edema), a medical emergency, with severe shortness of breath. Chronic (long-term exposure) health effects can occur at some time after exposure to and can last for months or years. Very high chronic exposure may cause lung damage. Sodium hydroxide has not been tested for ability to cause cancer in animals. There is no evidence it .effects reproduction.

OSHA: The legal airborne permissible exposure limit (PEL) is 2 mg/m3 averaged over an 8-hour work shift. NIOSH: The recommended airborne exposure limit is 2 mg/m3, which should not be exceeded at any time. The NIOSH IDLH value is 10 in in3. ACGIH: The recommended airborne exposure limit is 2 mg/m3, which should not be exceeded at any time. Recommended personal protective equipment (PPE): Appropriate, impervious, protective clothing (including gloves) should be worn to prevent skin contact. Protective equipment should not be made of aluminum, copper, soft iron, tin, or zinc (or alloys made of these metals. Eyes and face: For solid sodium hydroxide wear impact resistant eye protection with side shields or goggles. For liquids wear indirect -vent, impact and splash resistant goggles. A face shield along with goggles is recommended when working with corrosive, highly irritating or toxic substances. Contact lenses should not be worn when working with this substance. Eyewash fountains should be provided. Respiratory: Use NIOSH certified toxic dust respirator. A NIOSH 100 HEPA tight- fitting half -face unit is recommended (with fit testing). Where the potential exists for exposure over 2 mg/m3, use a MSHA/NIOSH approved supplied -air respirator with a full face piece operated in a pressure -demand or other positive -pressure mode. For increased protection use in combination with an auxiliary self-contained breathing apparatus operated in a pressure -demand or other positive -pressure mode. Exposure to 10 mg/m3 is immediately dangerous to life and health. If the possibility of exposure above 10 mg/m3 exists, use a MSHA/NIOSH approved self-contained breathing apparatus with a full face piece operated in a pressure -demand or other positive -pressure mode. Gloves: Impervious. ACGIH recommends polyvinyl chloride, butyl, butyl/neoprene, natural rubber, neoprene, polyethylene, Saranex, Teflon and Viton/neoprene as protective materials. First Aid: Eyes: Irrigate immediately Skin: Water flush immediately. Clothing which becomes significantly contaminated, or wet, should be removed as quickly as possible.
