INTRODUCTION This Interim Measure (IM) work plan proposes enhanced anaerobic dechlorination (EAD) and downgradient aerobic co-metabolic degradation to address volatile organic compound (VOC)- impacted groundwater at the Former Clifton Precision Site in Murphy, North Carolina (site) in accordance with the Final Decision and Response to Comments (FDRTC, 2017) under the Resource Conservation and Recovery Act (RCRA) Permit. This IM work plan is being submitted to the United States Environmental Protection Agency (EPA) and the North Carolina Department of Environmental Quality (NCDEQ) for review and approval prior to implementation. The IM will be implemented to reduce the VOC flux in groundwater from waste management unit (WMU)-B following completion of the in situ thermal remediation (ISTR) IM. Implementation will reduce the flux of VOCs downgradient consistent with EPA's FDRTC for a final remedy. Trichloroethene (TCE) is the VOC most frequently detected in downgradient groundwater that exceeds the Maximum Contaminant Levels (MCL). Additional VOCs detected above the MCLs at lower frequencies and concentrations include tetrachioroethene (PCE), cis-1,2-dichloroethene (DCE), vinyl chloride(VC), and 1,1-DCE. All of these VOCs are amenable to treatment by bioremediation. This IM will supplement previous IM work completed in 2015 and 2016, which consisted of ISTR to reduce elevated concentrations of VOCs present in soil and groundwater at WMU-B. The bioremediation IM will be designed and implemented to take advantage of technology synergies between ISTR and bioremediation, as elevated groundwater temperatures established during ISTR can enhance the rate of reductive dechlorination during EAD and co-metabolic aerobic degradation as the warm water flows out of the ISTR treatment zone. A site plan of facility and existing conditions showing the former ISTR area at WMU-B is included as Figure 2-1. This work plan provides the IM objectives, recommended IM remedial technology description, basis for selection, and preliminary design criteria and technical approach. The work plan also includes the anticipated reporting, permitting, and implementation schedule, and per the requirements of the Consent Order, the work plan contains personnel qualifications, reference to the existing Community Relations Plan, and details regarding health and safety plans. This work plan is specific to the proposed IM. Details regarding detailed site history, site features, hydrogeologic conditions, etc. can be found in the RCRA Facility Investigation Report (CDM Smith, 2013). 1.1 Brief Site Description/Background Information Operations at the facility began in 1967 with the manufacture of small electric rotary parts and electric motors. In 1998, the facility entered into an Administrative Order on Consent(Order) with the EPA. The Order identified eight WMUs. Several investigation and remediation activities were conducted from 1986 through 2003, including excavation of an underground storage tank (WMU-B), two phases of a RCRA Facility Investigation,and installation of groundwater extraction and soil vapor recovery systems. Land use in the site vicinity is primarily rural residential. The site is bounded to the north by Slow Creek with rural residential properties located to the north and the west. To the south, the site is bounded by commercial and industrial land uses, including a service station, hardware store, and manufacturing facility. The site is located on the border of a stream valley that drains to the south-southwest into the Hiawassee River. Surface topography and drainage on site is primarily to the north toward Slow Creek. Page 1-1 February 2018 Innovative Engineering Solutions,Inc. A previous report (CDM Smith, 2013) summarized the site conditions as follows: The site is also located in the Blue Ridge Physiographic Province, which consists predominantly of metamorphic rock of sedimentary origin. The subsurface investigations indicate a single aquifer that consists of three interconnected hydrogeologic zones: regolith,transition, and bedrock. The regolith is the shallowest zone and is composed of saprolite and alluvium. The transition zone is present in most locations on and off site and typically consists of fractured, partially-weathered rock. The bedrock zone is interpreted to consist of the Murphy Marble at all investigation locations. Fractures are present in both the transition and bedrock zones but occur at a higher frequency in the transition zone. The predominant direction of groundwater flow at the site is to the west and northwest. For groundwater, the highest concentration of total VOCs is on site near WMU-B, and the estimated extent of total VOCs stretches to the west and northwest from this WMU. The most frequently detected VOCs and those typically detected at the highest concentrations are 1,1,1-trichloroethane (TCA), 1,1- DCE,PCE,and TCE. VOCs in regolith groundwater migrate laterally to the west through the regolith, as well as downward to enter bedrock groundwater in the area of WMU-B. Downgradient of WMU-B toward the western site boundary,the transition zone becomes thicker and plays a more significant role in VOC migration because the transition zone has a higher transmissivity that allows groundwater to migrate more rapidly.VOCs are also present in groundwater along the northwest site boundary toward Slow Creek where the transition zone is not well-developed and a bedrock ridge exists. VOCs in offsite bedrock have similar migration and fate characteristics. The VOCs in bedrock groundwater migrate laterally on site. Off site, VOC migration is dictated by a bedrock trough, the alluvium, and inclined rock ledges interlayered with alluvium filled fractures. VOCs in the alluvium ultimately discharge to Slow Creek. TCE concentrations at the two surface water stations with the most historical detections are typically less than 10 µg/L, based on semi-annual sampling performed for the last several years.

INTERIM MEASURE OBJECTIVE & APPROACH The general objective of the IM is to reduce the VOC flux in groundwater from WMU-B to the recovery well system using bioremediation. EAD treatment will be implemented in the WMU-B area and beneath adjacent existing buildings. The EAD treatment system will remediate residual VOCs in groundwater that currently remain after thermal treatment. The proposed EAD system consists of numerous (116 existing and 6 proposed) injection wells/locations to deliver additives (electron donor, buffering agents, and di-ammonium phosphate) within the treatment zone. Immediately downgradient of the EAD anaerobic treatment zone is the EAD anaerobic transition zone,where the residual electron donor(carbon source) added upgradient in the treatment area will be biodegraded below the building and groundwater bio-geochemistry will begin to revert to more anoxic and aerobic conditions. Downgradient of these EAD zones (to the west/northwest of the buildings) will be an aerobic co-metabolic bioremediation zone to further remediate VOC residuals. Figure 2-2 presents the general locations of the treatment zones (EAD anaerobic treatment and transition, and aerobic treatment) and the locations where existing wells will be utilized and new remedial wells are projected to be installed. As described further in Section 3, Technical Approach, the work plan will include the following components in support of the overall objective: • Installation of 6 new injection/remediation wells (REW-1 to REW-6) to inject additives and groundwater; tap water will be used to dilute the additives and as post injection(chase) to better distribute the additives. • Utilization of 116 existing electrode wells for additive injection; electrode well construction details are included in Table 2-1. Note that not all the electrodes may be used at any one time, and only a portion of the boreholes may accept adequate injection volumes. A subset of the existing electrode wells was tested in 2017 (tap water injection) and based upon this short-term testing (15-20 minutes/location), approximately 90% of the existing electrode wells appear useable for amendment addition. • Installation of eight sets of oxygen sparge couplets downgradient of the EAD zone; on-site, facility-compressed air will be utilized in conjunction with a new oxygen generator. The EAD program will require an underground injection control (UIC) permit and an application will be submitted shortly to EPA and NCDEQ after submission of this work plan. The aerobic treatment zone will also serve to re-oxygenate groundwater in order to protect the existing pump and treat system from potential fouling due to anoxic conditions (induced reduction of iron and other metals). If successful,the bioremediation program, and possible future expansion, may allow for operation of the groundwater extraction and treatment system to be reduced and/or eliminated in the future. Implementation of source area EAD activities will be initiated as soon as the groundwater temperature has cooled to 40 degrees Celsius. The residual heat which emanates out of the ISTR zone following completion of heating can have substantial benefits for the EAD degradation process in downgradient areas. Based on the current aquifer geochemistry, conditions in target EAD treatment zones are not optimal for anaerobic degradation of contaminants and would need to be driven to strongly reducing conditions through injection of amendments. Additionally, it is anticipated that pH control, di-ammonium phosphate (inorganic nutrient) addition, and bioaugmentation culture addition will be required. Page 2-1 February 2018 Innovative Engineering Solutions,Inc. 3. TECHNICAL APPROACH 3.1 Conceptual Site Model WMU-B is the location of a former underground storage tank that received wastewater for treatment. The tank and surrounding soil were removed in 1987 and a groundwater extraction and treatment system was installed and operated in the WMU-B area until the ISTR project was initiated in 2015. A site perimeter groundwater containment system is currently operated using three recovery wells and offsite reinjection wells. Groundwater migrating through the WMU-B area is captured downgradient primarily by recovery well RW-4 and RW-5. This work plan is focused on VOCs in groundwater migrating from WMU-B toward RW-4 and RW-5. The subsurface conditions in the EAD area consist of an upper residuum layer underlain by the transition zone into bedrock. The residuum consists of clayey silt to silty sand with rock fragments derived from weathering of the underlying Murphy Marble. The residuum hydraulic conductivity is typically one to two feet per day but is variable because of variations in silt and clay content. The transition zone beneath the residuum consists primarily of weathered marble with alternating rock and fracture zones. The contact between these zones occur at various depths and are often irregular, with upper fractures typically containing residuum. The hydraulic conductivity at the contact between zones is typically much higher than the residuum and more variable because of the fractures. It is expected and stands to reason that most groundwater flow and contaminant migration occurred within the coarser-grained materials and fractures. Locating and mapping these specific areas of secondary porosity has not been successful at the site, so remedial wells will be screened across the entire targeted treatment zone to ensure that all areas receive remedial amendments. Areas with higher permeability will likely also have higher flow and associated contaminant mass, so preferential flow to these areas is acceptable. The bedrock aquifer is marble with fracture size and density typically decrease with depth, although fractures capable of producing high groundwater volumes can exist. The focus of the planned remediation includes the residuum,transition zone, and shallow bedrock. Figure 2-2 presents the conceptual layout of the proposed remedy, and a geologic cross section of this conceptual approach is shown on Figure 3-1. EAD will be implemented with the injection of additives in the main source area in a zone labeled "anaerobic treatment zone". EAD additives will generally affect groundwater within the treatment area designated as the "treatment zone". The treatment zone is the groundwater pore volume that is being remediated and is generally the area where additives are injected. The estimated maximum pore water volume expected to be treated within the EAD treatment zone is approximately 2.5 million gallons, based on an assumed porosity of 20 percent. The non-homogeneous nature of the subsurface conditions in this area, however, may significantly lower the effective porosity and the required treatment volume may vary from this estimate. Numerous existing thermal electrode wells combined with new injection wells within the anaerobic treatment zone will be used to distribute the additives over the targeted treatment area. A detail of the existing electrode well construction is shown in Figure 4-2, and a summary of all the electrode well's construction is presented in Table 2-1. These wells all have a section of conductive material (coarse sand with carbon)that is suitable for passing the dilute amendment solutions proposed. Existing plastic tubing leads to the bottom and top of the conductive material, and both will be used to delivered amendment solutions. There is approximately 5,126 linear feet of conductive material placed within the borehole of the well, this equates to almost one mile of screened interval for injecting amendments into the subsurface within the targeted treatment area. In addition, the locations and depths of these wells were selected previously during thermal treatment to target the highest VOC concentrations at the site,making them suitable delivery points for EAD additives; Figure 3-2 details the EAD zone well layout. The large Page 3-1 February 2018 Innovative Engineering Solutions,Inc. number of wells allows for relatively efficient delivery and distribution of the EAD additives within the targeted treatment zone even with relatively low injection volumes. IESI has used similar wells for this purpose at other sites to successfully implement anaerobic bioremediation for"polishing"remediation of VOCs following thermal remediation. The "transition zone" (Figure 2-2) is defined as the area immediately downgradient of the anaerobic treatment zone and is between the anaerobic treatment zone and the aerobic-co-metabolic treatment zone wells. It is the area where VOCs have been reduced by the EAD treatment, and residual total organic carbon (TOC) and methane will be biodegraded; groundwater conditions will begin to revert back to less anaerobic and more anoxic and aerobic conditions. The residual TOC and methane will fuel biodegradation of residual VOCs (anaerobically) in this transition zone. Downgradient of the transition zone is the aerobic treatment zone, where generated methane (from anaerobic reactions) will be aerobically metabolized (in the zone where oxygen will be added) to fuel the aerobic degradation of residual VOCs. There are limited pathways for oxygen to enter groundwater in the transition zone between the anaerobic zone and the aerobic zone, so the aerobic treatment zone should be well developed with high dissolved oxygen concentrations present in groundwater prior to amendment addition in the anaerobic zone. Establishing the aerobic treatment zone early is to prevent the introduction of anaerobic water into the existing extraction wells and limit the potential for associated fouling of the wells and the treatment system. The EAD system is expected to operate for at least 2-3 years and reduce VOC contaminant levels to less than 100 ug/L, on average, within the treatment zone. It is also expected that all wells within the treatment zone will achieve over 90% reduction in total VOC concentration. As discussed above, anaerobic dechlorination is not occurring at the site to any significant extent under current conditions because the groundwater is aerobic. As such, a sufficient electron donor must be added to the impacted zone to enhance anaerobic dechlorination. It is proposed to use an electron donor consisting predominantly of alcohol (methanol/ethanol; alcohol). Alcohols serve as excellent electron donors and keep the wells clean by acting as a disinfectant in the immediate vicinity of the injection well. Furthermore, alcohols do not generate salts upon degradation. The low viscosity of alcohol allows for its direct injection into the wells without significant dilution with water, thereby potentially separating the feeding (electron donor addition) from recirculation and reducing potential clogging problems/issues. Safety data sheets (SDS) for methanol/ethanol can be found in Appendix A. An alcohol chemical supplier has not been selected; however, the final SDS information will be similar for all vendors. Generally, alcohol will be injected the same day that it is received and will not be stored on site. All necessary fire department and other local permits will be obtained prior to system construction. Please refer to Appendix B for design basis calculations for the amendment dose. As a contingency, emulsified vegetable oil may be used if it appears that the subsurface conditions are suitable and a less mobile electron donor is desirable. These conditions may include, but are not limited to: high groundwater velocity causing high carbon loading to the aerobic treatment zone, too rapid biodegradation of alcohol, or aquifer formation is coarser-grained than expected. Review of the site analytical data indicates that minimal VC has been detected in the groundwater over the past 10 years. The lack of VC detections is indicative that the dehalococcoides ethenogenes (DE) microorganism is likely lacking at the site, as this microorganism is essential for transforming cis-1,2- DCE to VC and, subsequently, VC to ethene. As such, once anaerobic conditions have been established, this work plan proposes to bioaugment the impacted zone with the KB-1 dechlorinating culture. Site performance monitoring will include analysis for field parameters (dissolved oxygen, redox, pH) as well as a variety of biogeochemical parameters on a quarterly basis. The timing to bioaugment will be based upon a simplified weight of evidence approach. Several important parameters to consider are nitrate depletion, sulfate reduction, methane generation, iron reduction, low redox conditions and presence of Page 3-2 February 2018 Innovative Engineering Solutions,Inc. electron donor. Some/most of these conditions should be met at some/most locations prior to bioaugmentation. A round of baseline biogeochemical sampling will be conducted prior to finalizing the system design to more accurately predict electron donor demand. The baseline sampling event is described in Section 5.1 of this report. 3.2 EAD Amendment Distribution Bioremediation is a naturally occurring process. Some form of bioremediation typically occurs at most sites with VOC impacts to soil and groundwater. During bioremediation, the contaminant mass can be reduced by aerobic or anaerobic processes that mineralize the VOCs, transforming them to innocuous end-products. Although bioremediation is naturally occurring at most sites, the rate of bioremediation is often too slow or cannot keep up with the plume growth to effectively remediate the impacts. EAD involves active enhancement of subsurface conditions to make them more favorable for bioremediation. Most often, electron donor compounds, pH buffers, and bioaugmentation cultures are added to the subsurface to optimize the dechlorination reactions. These materials can be added through wells, trenches, or direct injection. These materials can then disperse through the aquifer under natural flow conditions, or their dispersion can be enhanced through active groundwater recirculation. Anaerobic dechlorination occurs when bacteria utilize chlorinated VOCs for respiration as alternate electron acceptors under anaerobic conditions (in place of oxygen), a process called halorespiration. This dechlorination process occurs naturally if anaerobic conditions are present in the water-saturated subsurface, or it can be enhanced in the subsurface with the introduction of biologically-degradable carbon substrates such as molasses, corn syrup, lactate, whey, oil, or alcohol. These substrates act as electron donors, and biological degradation of these substrates requires electron acceptors such as oxygen, nitrate, manganese, iron, sulfate, or the VOC targeted for dechlorination. Dechlorination typically occurs under sulfate-reducing and methanogenic conditions, when other electron acceptors are scarce and the energy yielded by halorespiration of VOCs is more favorable to the dechlorinating microorganisms. Dechlorination occurs first for the most heavily chlorinated VOCs, with PCE being degraded with the substitution of one chloride ion with one hydrogen ion to form TCE, which then degrades sequentially to cis-1,2-DCE, to VC, and then to ethene. Each step in the dechlorination process degrades one mole of the targeted VOC, requiring one mole of hydrogen and yielding one mole of hydrochloric acid. Dechlorination of high concentrations of VOCs can cause substantial alkalinity demand or a sharp drop in pH if sufficient buffering capacity is not present. Viability of microbial dechlorinating cultures is highly pH-dependent, and the dechlorination processes have been shown to slow substantially at pH levels below approximately 6.0. In these dechlorinating reactions, hydrogen is produced during the fermentation (which also increases acidity) of the organic substrate (electron donors) by a mixed microbial community. The generated hydrogen serves as a direct electron donor for the reduction of the chlorinated compound. Figure 3-3 shows a schematic of the dechlorination reactions. An advantage of bioremediation is that the completed process destroys VOC contaminants, rather than transferring them to other media like many other remedial technologies. Bioremediation also enhances desorption of VOCs from water-saturated soil into the groundwater, where the contaminants can be degraded. This enhanced desorption is a major advantage of bioremediation over other in-situ technologies. Additionally, enhanced bioremediation can be implemented with other active and/or Page 3-3 February 2018 Innovative Engineering Solutions,Inc. passive remedial technologies to further the overall remediation and has the highest likelihood of all technologies to reduce VOC concentrations to fairly low levels,thereby achieving site closure goals. The design of a bioremediation system is based upon an understanding of the basics of anaerobic and aerobic microbial growth and the associated contaminant/VOC biodegradation. Bioremediation systems that involve the enhancement of these biodegradation processes through amendment addition generally have the following common design objectives: 1. Select and properly distribute the additives in sufficient amounts. 2. Adjust and maintain a neutral pH. 3. Maintain suitable geochemical conditions and amendment distribution for sufficient time until remediation is complete. The maintenance of sustained electron donor concentration in the groundwater enhances desorption of VOCs from the saturated soil and expedites site clean-up. Amendments may include electron donor, buffering agents, and bioaugmentation microorganisms. Amendment distribution can be accomplished by three broad categories of delivery methods: stationary phase additives, dilute additives, and groundwater recirculation. Injection of dilute amendments (approach 2 below) will be implemented at the subject site. Pending UIC approval, Northrop Grumman may eventually convert the dilute additive injection system into a groundwater recirculation system (approach 3 below): 1. Stationary Phase Systems: Semi-solid amendments diffuse into the aquifer, such as the hydrogen release compound (HRC) manufactured by Regenesis, or slow release materials such as chitin and mulch. In general additive distribution using this approach is not uniform and often leads to incomplete remediation. As such, this additive injection approach will not be utilized. 2. Injection of Dilute Liquid Electron Donor: Amendments are injected into wells (vertical or horizontal) or trenches without inducing significant groundwater movement. In general additive distribution using this approach can be acceptable if sufficient volume of make-up groundwater or tap water is injected into a sufficient number of injection locations to affect large portions of the aquifer. Due to the large number of available injection locations, this approach is expected to be successful. This approach will initially be utilized at the site to render groundwater anaerobic and the system will operate in this mode for at least 2 years. 3. Groundwater Extraction with Reinjection of Amended Groundwater: Extracted groundwater is mixed with amendments to distribute the additives. Groundwater extraction, amendment, and upgradient injection represents the most effective technique to distribute amendments in the zone to be remediated. The amendments can be added in batch basis and distributed by the recirculation system, or can be metered into the groundwater process stream. The most conventional approach for amendment distribution is groundwater extraction from vertically- drilled wells, and subsequent injection into upgradient, vertically-drilled wells. This approach induces groundwater flow from all depths and provides vertical mixing. The initial batch injection approach may be modified in the future (after petitioning and gaining approval from the NCDEQ UIC branch) to include continuous recirculation. If such UIC approval is granted,Northrop Grumman may install additional extraction wells to recirculate additives and groundwater on a continuous basis. The initial installation of the batch system injection will manifold all the injection locations into several vaults and, as such, the conversion to continuous recirculation will only involve the connection of new extraction wells to the manifold vaults. Page 3-4 February 2018 Innovative Engineering Solutions,Inc. 3.3 Methanotrophic Co-Metabolic Degradation This technology involves injection of a substrate/co-metabolite and an oxygen source into the subsurface. Certain microorganisms grown aerobically on a variety of substrates/co-metabolites express oxygenase enzymes that are capable of transforming TCE, cis-1,2-DCE, and VC. These microorganisms are called methanotrophs if methane is the co-metabolite, and propanotrophs if propane is the co-metabolite. Transformation of chlorinated ethenes by the oxygenase enzymes results in the formation of intermediate epoxide compounds (epoxides), which are breakdown products of the chlorinated VOCs. These epoxides, which are electrophilic compounds, are highly reactive and unstable in aqueous solution. The reactivity of the epoxides and their degradation products often results in covalent modification of cellular microbial components, including the organism producing the enzymes, causing transformation product toxicity, meaning that the product (epoxide) generated by the reaction inhibits further reaction, as the microbes are damaged by the epoxides. Consequently, the amount of chlorinated ethene that can be transformed is limited due to transformation product toxicity. In general, 3-10 milligrams/liter of TCE can be degraded using this approach without inducing toxicity. The most common co-metabolite is methane. Residual low concentrations of methane will be generated from application of EAD in the upgradient former source area. When this methane migrates to an area that has residual oxygen, or if oxygen is added by oxygen sparging, it can rapidly degrade most chlorinated VOCs (i.e., TCE, cis-1,2-DCE, and VC; it will not degrade PCE). As such, this technology serves as a polishing step to EAD at locations where dechlorinators may not flourish due to suffocation issues from low VOC concentrations. Oxygen will be delivered to the subsurface by injection into a network of eight couplet wells (so 16 wells total). Additional subsurface piping will be installed so the number of oxygen sparge wells can be increased if needed. Compressed air from the facility will be utilized and separated into 90% pure oxygen by an oxygen generator to limit the storage of oxygen gas. A manifold system will be used to control the flow of oxygen to the sparge wells. The amount of oxygen delivered to each sparge well will be dependent on the oxygen demand at that location as determined from recent groundwater data. Oxygen will be cycled and pulsed to each of the sparge wells with a PLC-based control panel and associated solenoid valves. Dissolved oxygen concentrations up to 45 mg/1 can be obtained when using oxygen (instead of air) so the sparge well spacing can be much larger than with air sparging and the oxygen delivered can meet much higher demands and/or travel further in groundwater. Once sparged into the subsurface, the oxygen will mix with the low levels of methane emanating from the transition zone, creating a hospitable environment for naturally-occurring methanotrophs to degrade residual VOCs. The dissolved oxygen will also act to protect the existing groundwater extraction and treatment system from anaerobic groundwater and associated fouling issues. 3.4 Permitting Injection of remediation amendments and tracers in North Carolina is regulated under North Carolina Administrative Code (NCAC). A UIC permit will be submitted to NCDEQ Division of Water Resources (DWR) in support of this plan. Initially a permit to allow batch injection (with tap water flushing) will be submitted for approval while a recirculation-based permit is pursued. It is possible that the NCDEQ —DWR UIC program will not accept/permit groundwater recirculation at the site and the initially proposed tap water flushing approach may operate for additional time. Page 3-5 February 2018 Innovative Engineering Solutions,Inc. 4. PROPOSED INTERIM MEASURES DETAILS As the experience base has grown, it is the current belief that that microcosm testing(and pilot testing) is not required at sites with "normal" biogeochemical conditions such as this site and therefore microcosm testing will not be performed. Once the groundwater is made anaerobic, the VOCs will dechlorinate if the right dechlorinating bacteria are present in the subsurface. Because minimal VC or ethene concentrations have been detected at the site, it is likely that bioaugmentation is required. Electron donor selection is based upon delivery requirements and substrate costs. There is no need to conduct testing for electron donor selection (Fam, 2012; Falatko, 2010). The historical operation of the pump and treat system provides adequate hydraulic information to eliminate the need for pump testing, hydraulic testing, or pilot testing (Fam, 2006). As such, there is a high level of confidence in the determination that neither microcosm nor pilot testing is required for the proposed activities. 4.1 EAD Treatment Area Wells The EAD system will include the following injection wells: • New injection wells (REW-1 to REW-6; 4-inch diameter) drilled to approximately 100 feet below ground surface (bgs). • Existing bedrock electrode wells. Groundwater will be injected into a number of these wells that are found to be suitable. Up to 116 (all existing useable points) locations may be used. These wells may only receive low volumes of additives due to their sand pack design, they will likely accept 0.25 to 0.5 gallon/minute. 4.2 EAD Delivery System Overview Electron donor will be batch-injected into the proposed injection locations in conjunction with tap water. pH buffering agents, such as dilute potassium/sodium hydroxide, will also be injected along with nutrients consisting of dilute solutions of di-ammonium phosphate. Following batch injections, small volumes of tap water (100-1,000 gallons per injection location) will be injected to better distribute the additives in the subsurface. Once the groundwater conditions become anaerobic, the injection wells will receive bioaugmentation culture. A process flow diagram of the proposed EAD approach is included on Figure 4-1. Under anaerobic conditions, the added electron donor will be completely converted to methane and carbon dioxide within 120 to 360 days. As such, the goal of the amendment delivery system will be to distribute the electron donor prior to its consumption. Preliminary calculations for electron donor dosing indicate that approximately 10,000 gallons of electron donor(-70,000 pounds of substrate) should be added per year. These dosing calculations are based upon average measured groundwater flow across the treatment area, estimated electron donor half-lives, and meeting the site's groundwater demand for electron donor. The demand is the required dosage to reduce electron acceptors in the groundwater. The dosing calculations are shown in Appendix B; more detailed amendment dosing information is provided in Section 4.4 of this report. 4.3 Bioaugmentation Details As indicated above, once anaerobic conditions have been established, Northrop Grumman plans to bioaugment the subsurface with the KB-1 culture. The KB-1 culture contains active DE microorganisms that can transform PCE to ethane. The culture also contains active dehalobacter which is the organism Page 4-1 February 2018 Innovative Engineering Solutions,Inc. that can convert 1,1,1-TCA to chloroethane. The KB-1 culture was developed and is sold by SIREM labs of Ontario, Canada. Bioaugmentation of the groundwater is expected only twice, but the actual number of bioaugmentation cycles will be dependent on data collected during the remediation. Based on two bioaugmentation events, it is estimated that a total of 260 liters of KB-1 will be added. 4.4 EAD System Details 4.4.1 New Injection Wells As described above, the EAD system will use both existing electrode wells and new wells. The new remedial injection wells will be 4 inches in diameter and stainless steel construction, and will be drilled to a depth of approximately 15 feet into bedrock, or up to approximately 100 feet bgs; remedial well construction details are shown on Figure 4-2. The wells will be screened with wire-wound screen from approximately 20-25 feet bgs to the base of the well. The existing piping within the electrode wells will be utilized for injection of amendments and tap water chase. All drilling waste will be tested for residual VOCs using EPA Method 8260. Soil will be properly characterized and managed via offsite treatment/disposal. Groundwater produced during drilling or drained from soil produced during drilling will be contained and treated by the onsite groundwater treatment system to the extent practical; liquids with a high solids content will be managed via offsite treatment/disposal. 4.4.2 Additive Injection The following is a list of proposed additives: • Primary Electron Donor: Methanol/Ethanol(expected volume of up to 30,000 gallons/year) • Contingency Electron Donor: Vegetable Oil(expected volume of up to 10,000 gallons/year) • pH buffering: Potassium/Sodium Hydroxide(expected volume of up to 50 gallons/year) • Di-Ammonium Phosphate(expected amount of up to 1,500 lbs./year) • Bioaugmentation culture: KB-1 (contains dehalococcoides and dehalobactor species; expected volume of up to 260 liters). • Cleaning Solution: Expected that acid cleaning of the injection wells will be required. Acid cleaning will involve injection of approximately 10 gallons of hydrochloric/muriatic acid into each well, with subsequent (after a short waiting period) extraction of the acid solution. Only very small amounts of acid will remain in the subsurface, since groundwater will be extracted until its pH is at least 3.0. • Methanol/Ethanol will be blended into a dilute alcohol/tap-water solution (up to 20% alcohol by volume) by metering it into dilution tap-water during feeding events (alcohol addition will be a manned operation) and then into the injection wells/electrode points. Northrop Grumman may also inject the alcohol without tap water and then chase the additives with tap water. Alcohol serves as a disinfectant in the immediate area of the injection well and as such can serve as a cleaning additive in addition to serving as an electron donor. Alcohol transfer will be conducted outdoors using an explosion-proof, pneumatic transfer pump. When diluted in water to 20% by volume or less, both ethanol and methanol are not flammable, nor do they generate vapors above the lower explosive limit. All equipment utilized in the transfer will be grounded per alcohol safe handling procedure manuals. The operator(s) will be wearing the requisite safety gear to ensure transfer operation safety. Safe alcohol handling procedures will be documented in the project operations and maintenance (O&M) manual. Electron donor injection will likely be conducted monthly/quarterly at the start of the project and feeding frequency will eventually be dictated by Page 4-2 February 2018 Innovative Engineering Solutions,Inc. groundwater monitoring well data. All additives will be injected at less than 20 psi at the wellhead. When potassium/sodium hydroxide injection is conducted, it will also be implemented as a dilute injection of hydroxide solution into the water stream directed to the injection wells. During periods of potassium/sodium hydroxide transfer, the operator will be wearing the requisite safety gear to ensure transfer operation safety. It is expected that each injection location will receive 100-1,000 gallons of tap water to better distribute injected additives, although if the newer injection wells can receive more volume during each injection, additional amendment mass and volume may be added if needed to promote development of the EAD zone and treatment process. Once the groundwater conditions become anaerobic, the injection wells will receive bioaugmentation culture. Bioaugmentation will simply involve manual (at the wellhead) addition of 1-10 liters of culture to selected injection(former electrode or new well)locations. The approach for each feeding injection may vary from the procedures described above. Northrop Grumman will evaluate the monitoring data to determine the actual additive delivery dosage, concentrations, and feeding rates. SDSs and other relevant information on the additives can be found in Appendix A. Chemical suppliers have not been selected; however,the final SDS information will be generally similar for all suppliers. Please refer to Figure 4-1 for a process flow diagram. 4.5 Transition Zone The proposed EAD system will generally affect groundwater within the treatment area designated as the "treatment zone". The treatment zone is the groundwater pore volume that is being remediated and is generally the area where additives are injected. The "transition zone" (Figures 2-2 and 3-1) is defined as the area between the treatment zone and the aerobic-co-metabolic wells. It is the area where VOCs have generally been reduced by the EAD treatment, residual TOC and methane are being biodegraded, and residual TOC and methane will continue to fuel degradation of residual VOCs (anaerobically) in this zone. As groundwater moves across and out of the transition zone, it will become less anaerobic and transition back toward aerobic conditions at the northwest side of the facility buildings. 4.6 Aerobic Co-Metabolic Zone Aerobic conditions will be generated on the west and northwest side of the facility buildings by injecting oxygen into a set of 16 oxygen sparge wells installed in pairs at eight locations. At each location, two small, one-inch diameter sparge wells will be installed within the same drilled borehole, with the deeper sparge well set into the top of bedrock, and the shallower one set at the bottom of the transition zone. The wells will be drilled to depths appropriate based on the geology encountered and fractures observed. Each well will have two-feet of one-inch diameter stainless steel screen at the base, and will be constructed above this with one-inch diameter schedule 40 well casing(see Figure 4-2). Oxygen will be generated by an oxygen generator that is supplied with facility-compressed air and sparged into groundwater in the manner discussed previously. Please refer to Figure 4-1 for a process flow diagram. Page 4-3 February 2018 Innovative Engineering Solutions,Inc. 5. MONITORING,REPORTING AND SCHEDULE 5.1 Monitoring and Analytical Program 5.1.1 New Monitoring Wells Additional monitoring wells are needed at three locations downgradient from the transition zone to monitor the effectiveness of the EAD treatment and the associated aerobic co-metabolic treatment zone. At two of these locations, shallow monitoring wells MW-8 and MW-12 already exist, but need to have an additional monitoring well set in the transition zone depth between the residuum and bedrock, and another set in the upper bedrock if water-bearing fractures are present there. A third location (preliminarily referred to as PM-10), southeast of RW-2 and RW-5, would be a new monitoring well cluster with potentially all three well depths installed. The proposed locations of PM-10, MW-8, and MW-12 are shown on Figure 2-2. 5.1.2 Baseline and Performance Monitoring Baseline monitoring prior to implementation of remediation will be conducted at up to 30 existing groundwater monitoring wells, in close proximity to the proposed remediation areas; this may include the following locations: • PM-1S/D • PM-2S/D • PM-3 S/D • PM-4S/D • PM-5S/D • PM-6S/D • PM-7S/D • PM-8 • PM-9S/D • PM-10 (new monitoring location with up to 3 new wells, all wells in cluster) • MW-12 (with up to 2 new wells, all wells in cluster) • MW-8 (with up to 2 new wells, all wells in cluster) • MW-37 • MW-32 • RW-4 All sampling and analysis described in this section will be completed in accordance with the requirements of the existing project Quality Assurance Project Plan (Conestoga-Rovers & Associates [CRA] 2010a). Performance monitoring will be conducted on a quarterly basis. More frequent sampling at selected locations may be conducted on an as needed basis. Performance monitoring will be implemented at up to 15 existing groundwater monitoring wells in close proximity to the proposed remediation areas as selected from the above list of baseline monitoring wells. The wells selected to be monitored may change with each sampling event depending on the previous data and current operations. It is expected that the monitoring wells selected to evaluate performance of the EAD system will primarily be from the PM well series within the anaerobic treatment area, and the PM-10, MW-8, and MW-12 series wells will be used to evaluate the performance of the aerobic treatment system. Table 5-1 lists the well construction details of the existing PM series wells located within the EAD treatment area. Page 5-1 February 2018 Innovative Engineering Solutions,Inc. Performance will be evaluated by assessing indicators of amendment distribution and longevity, redox parameters and general aquifer geochemistry, and dechlorination activity. TOC will be used to evaluate amendment distribution and longevity. Dissolved oxygen, oxidation-reduction potential, sulfate, nitrate, total iron, total manganese, sulfide and methane will be used to evaluate redox conditions in the aquifer. Alkalinity, pH, temperature, chloride, and specific conductance will also be used to evaluate aquifer geochemical conditions. Chlorinated VOCs, ethene, ethane, methane will be used to evaluate clean-up progress. Selected wells may also be analyzed for the presence of DE. This section summarizes the reports and plans that will be prepared as part of the IM program. Each document will be submitted to the EPA and the NCDEQ for review and approval. 5.2 Design Report The design report will be prepared following EPA and NCDEQ approval of this work plan. The report will include drawings and more detailed system information. In consideration that Northrop Grumman will prepare a similar design document to attain the UIC permit, the design report may be a slightly modified version of the UIC permit report. 5.3 Quality Assurance Documents In accordance with the Consent Order, several documents have already been prepared, or will be prepared, to maintain quality control: • Quality Assurance Project Plan (CRA, 2010a) — This document highlights how information and data will be collected to ensure that they are technically sound, statistically valid, and properly documented. • Sampling and Analysis Plan (CRA, 2010b) — This document is a companion document to the Quality Assurance Project Plan and specifically describes how field data will be collected. • Data Management Plan (CRA, 2010c) —This document is a companion document to the Quality Assurance Project Plan and identifies how investigation data will be tracked and managed. • Construction Quality Assurance Plan—This plan will be created prior to project implementation to outline the construction quality assurance program, including responsibilities and authority, inspection activities, sampling requirements, and documentation. 5.4 Other Supplemental Documents Other supplemental documents pertinent to the proposed program are as follows: • Community Relations Plan—A Community Relations Plan (CDM, November 2008: Revisionl) was previously prepared for this project and will be followed. • Health and Safety Plan—A health and safety plan that satisfies the Hazardous Waste Operations and Emergency Response Standard (U.S. Occupational Safety and Health Administration Standard 1910.120) is used for all hazardous waste assessment, monitoring, and remediation activities at the site. An updated plan will be submitted. 5.5 Completion Report At the completion of project implementation and the performance monitoring described in this work plan, a Completion Report will be prepared to summarize project activities and provide performance results. This report will include a certification that construction was completed in Page 5-2 February 2018 Innovative Engineering Solutions,Inc. accordance with the design documents, with any exceptions noted. This report will also include results and an evaluation of whether performance objectives were met. 5.6 Schedule The estimated schedule for activities up to construction is shown in Figure 5-1. This schedule seeks to achieve aggressive targets for implementation. Actual durations may vary depending on the length of regulatory approvals and the time required for temperature in the bioremediation treatment area to reach optimal levels following completion of ISTR treatment. The expected duration of project implementation activities will be further evaluated during design and incorporated into future schedules.

HAZARDS IDENTIFICATION Potential Acute Health Effects: Eye Contact: Causes mild to moderate eye irritation. High vapor concentration or liquid contact with eyes causes irritation, tearing and burning. Skin Contact: Causes moderate skin irritation. May be absorbed through the skin in toxic or lethal amounts. Symptoms of exposure may include: Central nervous system depression with headache, stupor, uncoordinated or strange behaviour or unconsciousness. Prolonged and or repeated skin contact with methanol soaked material has produced toxic effects including vision effects and death. LA1183 Methanol Page 1 of 8 3. HAZARDS IDENTIFICATION Inhalation: Inhalation of high airborne concentrations can irritate mucous membranes, cause headaches, sleepiness, nausea, confusion, loss of consciousness, digestive and visual disturbances and death. NOTE: Odour threshold of methanol is several times higher than the TLV-TWA. Depending upon severity of poisoning and the promptness of treatment, survivors may recover completely or may have permanent blindness, vision disturbances and/or nervous system effects. Concentrations in air exceeding 1000 ppm may cause irritation of the mucous membranes. Ingestion: May be fatal if swallowed. A small amount of methanol (usually two or more ounces)can cause mental sluggishness, nausea and vomiting leading to severe illness, and may produce adverse effects on vision with possible blindness or death if treatment is not received. Aspiration into the lungs may occur during ingestion or vomiting, resulting in lung injury. 4. FIRST AID MEASURES Eye Contact: Remove contact lenses, if worn. Flush immediately with gentle running water for a minimum of 15 minutes, ensuring all surfaces and crevices are flushed by lifting lower and upper lids. Obtain medical attention. Skin Contact: Remove contaminated clothing and shoes. In case of contact, immediately flush skin with plenty of soap and water for at least 15 minutes. If irritation persists get medical attention. Wash clothing before reuse. Thoroughly clean contaminated shoes. Prolonged contact with methanol may defat skin tissue, resulting in drying and cracking. Inhalation: Remove to fresh air, restore or assist breathing if necessary, obtain medical attention immediately. Ingestion: If swallowed, do not induce vomiting. Never give anything by mouth to an unconscious person. Obtain medical help immediately. Onset of symptoms may be delayed for 18 to 24 hours after ingestion. Swallowing methanol is life threatening. Notes to Physician: Acute exposure to methanol, either through ingestion or breathing high airborne concentrations can result in symptoms appearing between 40 minutes and 72 hours after exposure. Symptoms and signs are usually limited to CNS, eyes and gastrointestinal tract. Because of the initial CNS's effects of headache, vertigo, lethargy and confusion, there may be an impression of ethanol intoxication. Blurred vision, decreased acuity and photophobia are common complaints. Treatment with ipecac or lavage is indicated in any patient presenting within two hours of ingestion. A profound metabolic acidosis occurs in severe poisoning and serum bicarbonate levels are a more accurate measure of severity than serum methanol levels. Treatment protocols are available from most major hospitals and early collaboration with appropriate hospital is recommended. In cases of methanol poisoning, medical care must emphasize the control of acidosis. The use of intravenous bicarbonate has been lifesaving. Evidence shows that the treatment of methanol absorption is enhanced through the administration of ethanol, which should be given to produce a blood level of at least 0.1%. Ethanol diminishes the production of the toxic metabolites of methanol. A blood methanol level of 50 mg/100m1 is an indication for hemodialysis, which has improved the prognosis of methanol intoxification. If more than 2.0 mL/kg has been ingested, vomiting should be induced with supervision. 5. FIRE FIGHTING MEASURES Flash Point: 11 °C/52 °F Flash Point Method: Tag Closed Cup Autoignition Temperature: 385°C/725°F Flammable Limits in Air(%): Lower: 6% Upper: 36% Extinguishing Media: Small fires: Dry chemical, CO2, water spray Large fires: Water spray(see note in Unsuitable Extinguishing Media), AFFF(R) (Aqueous Film Forming Foam (alcohol resistant))type with either a 3% or 6%foam proportioning system. Unsuitable Extinguishing Media: General purpose synthetic foams or protein foams may work, but much less effectively. Water may be effective for cooling, but may not be effective for extinguishing a fire because it may not cool methanol below its flash point. Special Exposure Hazards: Flammable Liquid. Isolate and restrict area access. Stay upwind. Methanol burns with a clean clear flame that is almost invisible in daylight. Concentrations of greater than 25% methanol in water can be ignited. Use fine water spray or fog to control fire spread and cool adjacent structures or containers. Contain fire control water for later disposal. Vapors are heavier than air and may accumulate in low areas. Vapors may travel along the ground to be ignited at distant locations. Closed containers may rupture violently or explode and suddenly release large amounts of product when exposed to fire or excessive heat for a sufficient period of time. Hazardous Decomposition/Combustion Materials (under fire conditions): Carbon monoxide. Carbon dioxide. Formaldehyde. LA1183 Methanol Page 2 of 8 5. FIRE FIGHTING MEASURES Special Protective Equipment: Fire fighters must wear full face, positive pressure, self-contained breathing apparatus and appropriate protective clothing. Note that methanol fires may require proximity suits. Do not walk through spilled product. Thoroughly decontaminate bunker gear and other fire-fighting equipment before re-use. NFPA RATINGS FOR THIS PRODUCT ARE: HEALTH 1, FLAMMABILITY 3, INSTABILITY 0 HMIS RATINGS FOR THIS PRODUCT ARE: HEALTH 1, FLAMMABILITY 3, REACTIVITY 0 6. ACCIDENTAL RELEASE MEASURES Personal Precautionary Measures: Full-face, positive pressure self-contained breathing apparatus or airline and protective clothing must be worn. Environmental Precautionary Measures: Prevent from entering into soil, ditches, sewers, waterways and/or groundwater. Consult local authorities. Biodegrades easily in water. Methanol in fresh or salt water may have serious effects on aquatic life. A study on methanol's toxic efffects on sewage sludge bacteria reported little effect on digestion at 0.1%while 0.5% methanol retarded digestion. Methanol will be broken down to carbon dioxide and water. Procedure for Clean Up: Flammable liquid. Eliminate all ignition sources. Isolate hazard area and restrict access. Stop leak only if safe to do so. Do not walk through spilled product as it may be on fire and not visible. Release can cause an immediate fire/explosion hazard. Fluorocarbon alcohol resistant foams may be applied to spill to diminish vapour and fire hazard. Maximize recovery for recycling or reuse. Restrict access to unprotected personnel. Ensure clean-up is conducted by trained personnel only. Ensure disposal is in compliance with all applicable government requirements. Small spills: soak up with absorbent material and scoop into containers. Large spills : prevent contamination of waterways. Dike and pump into suitable containers. Clean up residual with absorbent material, place in appropriate container and flush with water. 7. HANDLING AND STORAGE Handling: For industrial use only. Handle and open containers with care. Avoid contact with eyes, skin and clothing. Do not ingest. Avoid inhalation of chemical. DO NOT handle or store near an open flame, heat, or other sources of ignition. Fixed equipment as well as transfer containers and equipment should be grounded to prevent accumulation of static charge. DO NOT pressurize, cut, heat, or weld containers. Empty containers may contain hazardous product residues. Keep the containers closed when not in use. Protect against physical damage. Use appropriate personnel protective equipment. Storage: Store in a cool, dry, well ventilated area, away from heat and ignition sources. Place away from incompatible materials. Tanks must be grounded and vented and should have vapour emission controls. Tanks must be diked. A flammable mixture of methanol vapour and air is possible inside a storage tank or transportation tank, and handlers should take appropriate precautions to reduce the risk of ignition. Handlers must eliminate ignition sources or purge the tank with an inert gas such as nitrogen. All equipment must be grounded - bonded when transferring product in order to avoid static discharge from the equipment, and subsequent possible fire. Anhydrous methanol is non-corrosive to most metals at ambient temperatures except for lead, nickel, monel, cast iron and high silicon iron. Coatings of copper(or copper alloys), zinc(including galvanized steel), or aluminum are unsuitable for storage. These materials may be attacked slowly by the methanol. Storage tanks of welded construction are normally satisfactory. They should be designed and built in conformance with good engineering practice for the material being stored. While plastics can be used for short term storage, they are generally not recommended for long-term storage due to deterioration effects and the subsequent risk of contamination. Corrosion rates for several construction materials: <0.508 mm/year: Cast iron, monel, lead, nickel <0.051 mm/year: High silicon iron Some attack: Polyethylene Satisfactory: Neoprene, phenolic resins, polyesters, natural rubber, butyl rubber Resistant: Polyvinyl chloride, unplasticized LA1183 Methanol Page 3 of 8 8. EXPOSURE CONTROLS/PERSONAL PROTECTION Engineering Controls: Use process enclosure, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits. Use explosion proof equipment.

TOXICOLOGICAL INFORMATION Principle Routes of Exposure Ingestion: May be fatal if swallowed. A small amount of methanol (usually two or more ounces)can cause mental sluggishness, nausea and vomiting leading to severe illness, and may produce adverse effects on vision with possible blindness or death if treatment is not received. Aspiration into the lungs may occur during ingestion or vomiting, resulting in lung injury. Skin Contact: Causes moderate skin irritation. May be absorbed through the skin in toxic or lethal amounts. Symptoms of exposure may include: Central nervous system depression with headache, stupor, uncoordinated or strange behaviour or unconsciousness. Prolonged and or repeated skin contact with methanol soaked material has produced toxic effects including vision effects and death. Inhalation: Inhalation of high airborne concentrations can irritate mucous membranes, cause headaches, sleepiness, nausea, confusion, loss of consciousness, digestive and visual disturbances and death. NOTE: Odour threshold of methanol is several times higher than the TLV-TWA. Depending upon severity of poisoning and the promptness of treatment, survivors may recover completely or may have permanent blindness, vision disturbances and/or nervous system effects. Concentrations in air exceeding 1000 ppm may cause irritation of the mucous membranes. Eye Contact: Causes mild to moderate eye irritation. High vapor concentration or liquid contact with eyes causes irritation, tearing and burning. Additional Information: Repeated exposure by inhalation or absorption of methanol may cause systemic poisoning, brain disorders, impaired vision and blindness. Inhalation may worsen conditions such as emphysema or bronchitis. Repeated skin contact may cause dermal irritation, dryness and cracking. Effects of sub lethal doses may be nausea, headache, abdominal pain, vomiting and visual disturbances ranging from blurred vision to light sensitivity. Methanol is toxic by inhalation and ingestion. Inhalation of vapors may cause cyanosis, CNS effects, lethargy, loss of consciousness and death. The effects from inhalation may be delayed. Ingestion may cause malaise, CNS effects, discomfort, and death if not treated promptly. Ingestion of methanol has resulted in adverse effects (necrosis and haemorrhaging) in the brain. Medical conditions aggravated by exposure include: skin disorders and allergies, liver disorders and eye disease. Undocumented reports suggest that this product may form a siloxane polymer on the eyes, lungs, or other mucous membranes. Long term exposure to methanol has been associated with headaches, giddiness, conjunctivitis, insomnia and impaired vision. Dermal absorption of significant amounts of methanol resulted in death in several animal species. Toxic effects in animals exposed to methanol by inhalation include eye irritation, blindness and nasal discharge. Toxic effects observed in animals exposed to methanol by ingestion include CNS effects , gastrointestinal effects, anesthetic effects, damage to the optic nerve and acidosis. Synergistic Products: In animals, high concentrations of methanol can increase the toxicity of other chemicals, particularly liver toxins like carbon tetrachloride. Ethanol significantly reduces the toxicity of methanol because it competes for the same metabolic enzymes, and has been usd to treat methanol poisoning. Potential for Accumulation: Methanol is readily absorbed into the body following inhalation and ingestion. Skin absorption may occur if the skin is broken or exposure is prolonged. Once absorbed, methanol is rapidly distributed to body tissues.A small amount is excreted unchanged in exhaled air and the urine. The rest is first metabolized to formaldehyde, which is then metabolized to formic acid and/or formate. The formic acid and formate are eventually converted to carbon dioxide and water. In humans, methanol clears from the body, after inhalation or oral exposure, with a half-life of 1 day or more for high doses (greater than 1000 mg/kg)or about 1.5-3 hours for low doses (less than 100 mg/kg or 76.5-230 ppm (100-300 mg/m3)). Acute Test of Product: Acute Oral LD50: >5,000 (Rat) Acute Dermal LD50: 20 mL/kg (Rabbit) Acute Inhalation LC50: 64, 000 ppm (Rat) Carcinogenicity: LA1183 Methanol Page 5 of 8 Ingredients IARC - Carcinogens ACGIH -Carcinogens Methanol Not listed. Not listed. Carcinogenicity Comment: No additional information available. Reproductive Toxicity/Teratogenicity/Embryotoxicity/Mutagenicity: Methanol is reported to cause birth defects in rats exposed to 20 000 ppm. In experimental animals, methanol is fetotoxic, teratogenic and has produced significant behavioral abnormalities in offspring at dose levels not producing maternal toxic effects. Behavioural abnormalities were observed in the offspring of rats given drinking water containing 2% methanol. Methanol has produced mutagenic effects (somatic cells) in experimental animals. 12.

Always add the caustic to water while stirring;never the reverse.Containers of this material may be hazardous when empty since they retain product residues (dust,solids);observe all warnings and precautions listed for the product.Do not store with aluminum or magnesium.Do not mix with acids or organic materials. 8.Exposure Controls/Personal Protection Airborne Exposure Limits: -OSHA Permissible Exposure Limit(PEL): 2 mg/m3 Ceiling -ACGIH Threshold Limit Value(TLV): 2 mg/m3 Ceiling Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures below the Airbome Exposure Limits.Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source,preventing dispersion of it into the general work area.Please refer to the ACGIH document,Industrial Ventilation,A Manual of Recommended Practices,most recent edition,for details. Personal Respirators(NIOSH Approved): If the exposure limit is exceeded and engineering controls are not feasible,a half facepiece particulate respirator(NIOSH type N95 or better filters)may be worn for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier,whichever is lowest..A full-face piece particulate respirator(NIOSH type N100 filters)may be worn up to 50 times the exposure limit,or the maximum use concentration specified by the appropriate regulatory agency,or respirator supplier,whichever is lowest.If oil particles(e.g.lubricants,cutting fluids,glycerine,etc.)are present,use a NIOSH type R or P filter.For emergencies or instances where the exposure levels are not known,use a full-facepiece positive-pressure,air- supplied respirator.WARNING:Air-purifying respirators do not protect workers in oxygen-deficient atmospheres. Skin Protection: Wear impervious protective clothing,including boots,gloves,lab coat,apron or coveralls,as appropriate,to prevent skin contact. Eye Protection: Use chemical safety goggles and/or a full face shield where splashing is possible.Maintain eye wash fountain and quick-drench facilities in work area. 9.Physical and Chemical Properties Appearance: http://www.jtbaker.com/msds/englishhtml/s4034.htm 5/6/2010 SODIUM HYDROXIDE Page 3 of 4 White,deliquescent pellets or flakes.

Section 5 - Fire Fighting Measures: Non-flammable Flash Point: not applicable Upper flammable limit: not applicable Lower flammable limit: not applicable Section 6—Accidental Release Procedures Spilled KB-1®Dechlorinator should be soaked up with sorbant and saturated with a 10% bleach solution (prepared by making a one in ten dilution of diluted standard bleach [normally sold at a strength of 5.25% sodium hypochlorite] to disinfect affected surfaces. Sorbant should be double bagged and disposed of as indicated in section 12. After removal of sorbant, area should be washed with 10% bleach solution to disinfect. If liquid from the culture vessel is present on the fittings, non-designated tubing or exterior of the stainless steel pressure vessel liquid should be wiped off and the area washed with 10% bleach solution. Section 7 - Handling and Storage KB-1® Dechlorinator is shipped in stainless steel pressure vessels and connected to injection lines and inert gas is used to pressurize the vessel to displace the contents. KB- 1 R Dechlorinator should be handled with care to avoid any spillage. Vessels are shipped with 1 pound per square inch (psi) pressure; valves should not be opened until connections to appropriate lines for subsurface injection are in place. Storage Requirements: Avoid exposing stainless steel pressure vessels to undue temperature extremes (i.e., temperatures less than 0°C or greater than 30°C may result in harm to the microbial cultures and damage to the vessels). All valves should be in the closed position when the vessel is not pressurized to prevent the escape of gases and to maintain anaerobic conditions in the vessel. Avoid exposure of the culture to air as the presence of oxygen will kill dechlorinating microorganisms. Section 8 - Exposure Controls/Personal Protection Personal protective equipment: Skin: Protective gloves (latex, vinyl or nitrile)should be worn. Eye Protection: Wear appropriate protective eyeglasses or goggles when opening pressure vessels valves or when pressurizing vessels to inject contents into the subsurface.
