INJECTION PROCEDURE Provide a detailed description of all planned activities relating to the proposed injection facility including but not limited to: (1) construction plans and materials; (2) operation procedures; and (3) a planned injection schedule. Activities related to the storage and distribution of petroleum products at the Skyland Distributing facility have impacted the soil and ground water beneath the site. The results of previous ground -water monitoring events at the site indicate that concentrations of petroleum compounds in collected ground -water samples have declined since February 2002. This consistent decline in contaminant concentrations is largely attributable to degradation of dissolved petroleum compounds by aerobic (oxygen -demanding) microorganisms native to soil at the site. Following the release of contaminants on the subject property, native microorganisms in the aquifer have adapted to growth on contaminants. The microorganisms are aerobic and have the ability to break down the contaminants in the soil and ground water. The growth of the microbial population has been largely limited by the availability of oxygen. Skyland Distributing intends to accelerate the rate of biodegradation of petroleum compounds in ground water by injection of Oxygen Release Compound (ORC)TM into the saturated zone. Injection of ORCTM will increase the supply of oxygen (the limiting factor for aerobic microbes) to the contaminated aquifer. ORCTM is a commercially available, environmentally -safe product marketed for remedial applications by Regenesis. ORCTM is a formulation of magnesium peroxide (MgO2) that is intercalated with food grade phosphate ions to facilitate oxygen release into the saturated zone at a controlled rate. The product has been shown to promote aerobic biological degradation of petroleum compounds such as benzene, naphthalene, and ethylbenzene under pilot- and full-scale conditions. Drinking water wells or other receptors are not located in the vicinity of the proposed injection area. Ground -water sampling was conducted in November 2003 to determine initial chemical parameters (total petroleum hydrocarbon concentrations, biological and chemical oxygen demand, and ferrous iron and manganese concentrations) in the contaminated aquifer. These parameters and aquifer characteristics were entered into a web -based software application provided by Regenesis (www.regenesis.com) to evaluate the volume of ORCTM and density of injection points necessary to distribute the compound throughout the contaminant plume. A total of 45 injection points, on an approximate 9-foot grid pattern, will be advanced to a depth below the water table (approximately 11 feet bgs) in accessible areas of the ground -water contamination plume utilizing direct push boring equipment. The injection borings will be advanced using 1.75-inch diameter, expendable conical points composed of steel or aluminum. Upon reaching a depth of 11 feet bgs, the conical points will be detached and expended at the bottom of the borings. An ORCTM slurry mixture will be generated in accordance with manufacturer's recommendations and will then be injected through the external probe rods into the subsurface using a pump and hose system attached to the direct push boring equipment. The probe rods will be retrieved from the hole as the slurry is injected. The ORCTM injection slurry will be brought up to a depth of approximately 1.5 feet below ground 2 of 12 Skyland Distributing Facility — 51 Permit Application February 6, 2004 MACTEC Project No. 6590-03-1252 surface (bgs) in the borings, with one foot of hydrated bentonite to 0.5 feet bgs, and asphalt pavement patch to surface. Based on the number and depth of injection points, the soil conditions, the contaminant concentrations, and the equipment being used, we estimate 930 pounds of ORCTM will be required. We anticipate that slurry injection and installation and sealing of the injection points will be completed within three days. F. DESCRIPTION OF SHE Provide a brief description of the contamination incident and the incident number assigned by the Division of Water Quality staff in the Department's Regional Office: Soil contamination was initially identified near a diesel product line and fuel dispenser during a limited subsurface investigation conducted in November 2001. Two 10,000- gallon diesel aboveground storage tanks (ASTs) and one 5,000-gallon gasoline AST and associated piping and dispensers were removed from the site on January 23, 2002 (Figure 2). On January 25 and 26, 2002, 39 tons of contaminated soil was excavated from areas of petroleum staining near the former locations of the diesel fuel dispenser and diesel AST where the product line entered the subsurface. Soil was also removed from the former location of the gasoline dispenser and the underground product lines. Based on evidence of soil contamination in the former area of the fuel dispensers and underground product lines, an additional 600 cubic yards of contaminated soil was excavated to a depth of five to six feet below ground surface (bgs) on February 11, 2002. Approximately one to two feet of clean fill soil was placed in the bottom of the excavation, and approximately one foot of Number 57 washed stone was placed over the compacted soil. In anticipation of possible future remedial action at the site, an infiltration gallery consisting of one-inclr diameter PVC pipe was placed over the washed stone at a depth of two to three feet bgs (Figure 3). The gallery was covered with one foot of Number 57 washed stone and a Layerr of filter fabric. Clean soil was placed on top of the washed stone and compacted with a vibrating sheepsfoot roller to fill the remainder of the excavation. The disturbed area was subsequently paved by Skyland Distributing. Confirmation soil samples collected from the sidewalls of the excavation indicated that TPH-GRO and TPH-DRO concentrations exceeded the NCDENR reportable level in soil located at the base (below surficial ground water) and north and northeast of the excavation (Figure 2). Additional soil excavation was not feasible because of the proximity of a building, Weston Drive, and the subject property boundary (and off -site building). Following installation of one recovery well and three monitoring wells at the site, volatile and semi -volatile organic compounds (VOCs and SVOCs) were detected in ground -water samples collected from the area of the excavation and downgradient of the excavation. During an April 2003 ground -water monitoring event, two volatile and one semi -volatile organic compounds (VOCs and SVOC) were detected at concentrations that exceeded NCAC 2L Standards in ground -water samples collected from the two wells (MW-01 and RW-01) located at the former excavation area. Two VOCs were identified in samples 3of12 Skyland Distributing Facility — 51 Permit Application February 6, 2004 MACTEC Project No. 6590-03-1252 collected from downgradient monitoring wells (MW-02 and MW-03) at concentrations below the NCAC 2L Standard (Figure 4). SVOCs were not detected in samples collected from the downgradient monitoring wells. These results indicate that concentrations of VOCs and SVOCs above the NCAC 2L Standards extend less than 65 feet downgradient of the source area. On January 20, 2004, NCDENR granted approval for a Corrective Action Plan, dated December 16, 2003, which recommended that low -flow air injection into vadose zone soils be combined with injection of Oxygen Release CompoundTM (ORC) into surficial ground water for remediation of soil and ground -water contamination at the site. Incident Number assigned by NCDENR-DWQ: 86033. G. HYDROGEOLOGIC DESCRIPTION SECTION (G) MUST BE ORIGINALLY SEALED AND SIGNED BY A LICENSED GEOLOGIST Provide a hydrogeologic description, soils description, and cross section of the subsurface to a depth that included the known or projected depth of contamination. The number of borings shall be sufficient to determine the following: (1) the regional geologic setting; (2) significant changes in lithology; (3) the hydraulic conductivity of the saturated zone; (4) the depth to the mean seasonal high water table; and (5) a determination of transmissivity and specific yield of the aquifer to be used for injection (showing calculations). I have prepared the narrative contents in the following hydrogeologic description from a review of the pertinent geologic / hydrogeologic information. The following sections describe the regional geologic conditions and the methods employed to obtain physical data that support our discussion of the local geologic and environmental conditions. 4 of 12 Skyland Distributing Facility — 51 Permit Application February 6, 2004 MACTEC Project No. 6590-03-1252 G.1 Topographic Conditions Using the 1965 U.S.G.S. Topographic Map of the Skyland, NC Quadrangle, as shown on Figure 1, the topography in the vicinity of the site is relatively flat. The property is located at an approximate elevation of 2,240 feet NGVD. The general area surrounding the site appears to slope downward to the west-southwest towards an unnamed tributary, which is located approximately 500 feet west of the site. The tributary flows northwest into Lake Julian, which is located approximately 3,500 feet northwest of the site. G.2 Geology G.2.1 Regional Geology The site is located in the Blue Ridge Physiographic Province. Based on a review of the Geologic Map of North Carolina, dated 1985, the subject property is underlain by rocks consisting primarily of muscovite-biotite gneiss. The bedrock in this region is structurally complex and consists of crystalline rock that has been faulted and contorted by past tectonic movements. The rock has weathered to residual soils which form the mantle for the hillsides and hilltops. The typical residual soil profile in areas not disturbed by erosion or construction -related activities consists of clayey soils near the surface where weathering is more advanced and underlying sandy silt and silty sand. G.2.2 Site Geology On the basis of previous records related to drilling activities at the site, the following interpretation of the site geology was developed. On May 15, 2002, Altamont Environmental, Inc. advanced two soil borings and installed two ground -water monitoring wells (MW-02 and MW-03). The wells are located approximately 70 feet and 165 feet hydraulically downgradient of the source area (Figure 4). According to the Well Construction Records, soil encountered during advancement of the borings consisted of tan silty clay from ground surface to five feet below ground surface (bgs) and grey silt from five feet to thirteen feet bgs. On November 3, 2003, MACIEC advanced two exploratory hand -auger borings approximately 15 feet east of the former excavation area. Soil encountered during advancement of the hand -auger borings consisted of grey, very micaceous, sandy silt from ground surface to 10 feet bgs. On October 29, 2003, ground water was encountered at approximately 1 to 4 feet bgs in monitoring wells MW-01, MW-02, and MW-03. Copies of the well construction records for wells MW-02 and MW-03 are provided in Appendix A. HYDROGEOLOGIC INVESTIGATION The hydraulic conductivity is a constant of proportionality relating to the ease with which a fluid passes through a porous medium. Based on MACTEC's experience at sites with similar soil characteristics (i.e., micaceous sandy silts) in the Blue Ridge region, we estimate the hydraulic conductivity at the site to be approximately 2.0 to 2.5 ft/day. 5 of 12 Skyland Distributing Facility— 51 Permit Application February 6, 2004 MACTEC Project No. 6590-03-1252 In addition to hydraulic conductivity (k), the rate of groundwater movement (v) at the site is a function of hydraulic gradients (i) and the effective porosity (ne) of site soils, as indicated by the equation v = ki/ne. Based on published values for similar soils, the effective porosity of the soil at the site is estimated to be about 30 percent (Driscoll, 1986). The hydraulic conductivity of the soil estimated from previous investigations in the area is 2.0 to 2.5 feet/day. Based on the hydraulic conductivity range, a hydraulic gradient of 0.03 feet/foot (between wells MW-01 and MW-03), and an average effective porosity of 0.30, the linear velocity of ground water in soil at this site is estimated to range between 73.0 and 913 feet per year. . G3 Transmissivity and Specific Yield Transmissivity is the measure of the amount of water that can be transmitted horizontally by the full saturated thickness of the aquifer under a hydraulic gradient of 1. Transmissivity (7) is calculated as the product of the hydraulic conductivity (K) and the saturated thickness of the aquifer (b). In this instance, hydraulic conductivity has been estimated to range from 2.0 to 2.5 ft/day. Aquifer thickness is typically .estimated by determining either the maximum vertical extent of ground -water contamination or the depth to bedrock or other impervious soil layer. However, the shallow depth (total depths of 10 to 14 feet bgs) of monitoring wells and absence of additional information regarding subsurface conditions at the site precluded direct measurement of aquifer thickness. Based on MACTEC's experience at other sites in the area, we estimate the depth of bedrock at the site to be between 40 and 50 feet bgs. Based on a ground -water depth of 2.97 feet that was measured in well MW-01 in October 2003, the total saturated thickness of the aquifer is estimated to be between 37 and 47 feet. K = 2.0 feet/day K= 2.5 feet/day b = 37 feet b=47feet T=bK T = 37 ft x 2.0 ft/day = 74.0 ft2/day T,,.. = 47 ft x 2.5 ft/day = 117.5 ft2/day Specific yield is the ratio of the volume of water that drains from a saturated rock owing to the attraction of gravity to the total volume of the rock (Fetter, 1988). Published values of specific yield for soil types indicate that the average specific yield for silty soils is 18 %. H. MONITORING PROCEDURE Provide plans for proposed location and construction details of ground -water monitoring well network, including a schedule for sampling and analytical methods. Include any modeling/testing performed to investigate injectant's potential or susceptibility to change (biological, chemical or physical) in the subsurface. 6of12 Skyland Distributing Facility — 51 Permit Application February 6, 2004 MACTEC Project No. 6590-03-1252 A monitoring program will be initiated after the ORCTM injection event at the site to track enhanced degradation of the target compounds. Components of the monitoring program will include: Quarterly sampling and semi-annual reporting of wells MW-01 and RW-01 (source area wells) and MW-02 and MW-03 (downgradient plume -delimiting wells) during the first and last year of the corrective action program. The analytical results for the non -reporting quarters will be submitted to the Asheville Regional Office of NCDENR. Semi-annual sampling and annual reporting of the well network described above will be conducted during year two. The analytical results for the non -reporting semi-annual events will be submitted to the Asheville Regional Office of NCDENR. • Laboratory analysis of collected ground -water samples will be performed for purgeable aromatics, including naphthalene, by EPA Method 602. During the final year of post remediation sampling, additional analyses such as EPA Method 601 (including MTBE and IPE), EPA Method 504.1 (EDB), and EPA Method 625 will be performed for site closure purposes. Each monitoring report will include a brief historical summary of the site incident, problems experienced during the repotting period, how the system is•operating towards meeting the desired endpoints, if the contaminant plume is moving or changing in concentration, and recommendations to improve operations, if any. The report will also include a brief discussion of the methods utilized in obtaining samples and will include the laboratory analyses listed in a table by well identification number. The table will have a column that outlines analytical results and the North Carolina Groundwater Quality Standards. Samples exhibiting concentrations that exceed Groundwater Quality Standards will be highlighted in bold. The monitoring report will include maps that depict the following: 1. Estimated distribution of the dissolved -phase contaminant plume. A separate isopleth map for benzene will be provided. This map will display the levels of benzene concentrations in ground water with the use of inferred isoplethllines which connect points of equal concentrations. 2. Water table contour maps, with water levels shown in each well gauged, referenced to a surveyed datum. As the enhanced biodegradation of contaminants progresses, the concentrations of target compounds in the source area wells are expected to attenuate to levels below their respective State Ground -water Standards. Verification that ground -water clean-up goals have been achieved at the site will be obtained when the sampled wells exhibit compound concentrations that are below their respective State Ground -water Standards during four consecutive quarterly sampling events. 7 of 12 Skyland Distributing Facility — 51 Permit Application February 6, 2004 MACTEC Project No. 6590-03-1252 I.

INJECTION PROCEDURE Provide a detailed description of all planned activities relating to the proposed injection facility including but not Limited to: (1) construction plans and materials; (2) operation procedures; and (3) a planned injection schedule. Activities related to the storage and distribution of petroleum products at the Skyland Distributing facility have impacted the soil and ground water beneath the site. The results of previous ground -water monitoring events at the site indicate that concentrations of petroleum compounds in collected ground -water samples have declined since February 2002. This consistent decline in contaminant concentrations is largely attributable to degradation of dissolved petroleum compounds by aerobic (oxygen -demanding) microorganisms native to soil at the site. Following the release of contaminants on the subject property, native microorganisms in the aquifer have adapted to growth on contaminants. The microorganisms are aerobic and have the ability to break down the contaminants in the soil and ground water. The growth of the microbial population has been largely limited by the availability of oxygen. Skyland Distributing intends to accelerate the rate of biodegradation of petroleum compounds in ground water by injection of Oxygen Release Compound (ORC)TM into the saturated zone. Injection of ORCTM will increase the supply of oxygen (the limiting factor for aerobic microbes) to the contaminated aquifer. ORCTM is a commercially available, environmentally -safe product marketed for remedial applications by Regenesis. ORCTM is a formulation of magnesium peroxide (MgO2) that is intercalated with food grade phosphate ions to facilitate oxygen release into the saturated zone at a controlled rate. The product has been shown to promote aerobic biological degradation of petroleum compounds such as benzene, naphthalene, and ethylbenzene under pilot- and full-scale conditions. Drinking water wells or other receptors are not located in the vicinity of the proposed injection area. Ground -water sampling was conducted in November 2003 to determine initial chemical parameters (total petroleum hydrocarbon concentrations, biological and chemical oxygen demand, and ferrous iron and manganese concentrations) in the contaminated aquifer. These parameters and aquifer characteristics were entered into a web -based software application provided by Regenesis (www.regenesis.com) to evaluate the volume of ORCTM and density of injection points necessary to distribute the compound throughout the contaminant plume. A total of 45 injection points, on an approximate 9-foot grid pattern, will be advanced to a depth below the water table (approximately 11 feet bgs) in accessible areas of the ground -water contamination plume utilizing direct push boring equipment. The injection borings will be advanced using 1.75-inch diameter, expendable conical points composed of steel or aluminum. Upon reaching a depth of 11 feet bgs, the conical points will be detached and expended at the bottom of the borings. An ORCTM slurry mixture will be generated in accordance with manufacturer's recommendations and will then be injected through the external probe rods into the subsurface using a pump and hose system attached to the direct push boring equipment. The probe rods will be retrieved from the hole as the slurry is injected. The ORCTM injection slurry will be brought up to a depth of approximately 1.5 feet below ground 2 of 12 Skyland Distributing Facility — 51 Permit Application February 6, 2004 MACTEC Project No. 6590-03-1252 surface (bgs) in the borings, with one foot of hydrated bentonite to 0.5 feet bgs, and asphalt pavement patch to surface. Based on the number and depth of injection points, the soil conditions, the contaminant concentrations, and the equipment being used, we estimate 930 pounds of ORCTM will be required. We anticipate that slurry injection and installation and sealing of the injection points will be completed within three days. F. DESCRIPTION OF SITE Provide a brief description of the contamination incident and the incident number assigned by the Division of Water Quality staff in the Department's Regional Office: Soil contamination was initially identified near a diesel product line and fuel dispenser during a Limited subsurface investigation conducted in November 2001. Two 10,000- gallon diesel aboveground storage tanks (ASTs) and one 5,000-gallon gasoline AST and associated piping and dispensers were removed from the site on January 23, 2002 (Figure 2). On January 25 and 26, 2002, 39 tons of contaminated soil was excavated from areas of petroleum staining near the former locations of the diesel fuel dispenser and diesel AST where the product line entered the subsurface. Soil was also removed from the former location of the gasoline dispenser and the underground product lines. Based on evidence of soil contamination in the former area of the fuel dispensers and underground product lines, an additional 600 cubic yards of contaminated soil was excavated to a depth of five to six feet below ground surface (bgs) on February 11, 2002. Approximately one to two feet of clean fill soil was placed in the bottom of the excavation, and approximately one foot of Number 57 washed stone was placed over the compacted soil. In anticipation of possible future remedial action at the site, an infiltration gallery consisting of one -inch diameter PVC pipe was placed over the washed stone at a depth of two to three feet bgs (Figure 3). The gallery was covered with one foot of Number 57 washed stone and a layer of filter fabric. Clean soil was placed on top of the washed stone and compacted with a vibrating sheepsfoot roller to fill the remainder of the excavation. The disturbed area was subsequently paved by Skyland Distributing. Confirmation soil samples collected from the sidewalls of the excavation indicated that TPH-GRO and TPH-DRO concentrations exceeded the NCDENR reportable level in soil located at the base (below surficial ground water) and north and northeast of the excavation (Figure 2). Additional soil excavation was not feasible because of the proximity of a building, Weston Drive, and the subject property boundary (and off -site building). Following installation of one recovery well and three monitoring wells at the site, volatile and semi -volatile organic compounds (VOCs and SVOCs) were detected in ground -water samples collected from the area of the excavation and downgradient of the excavation. During an April 2003 ground -water monitoring event, two volatile and one semi -volatile organic compounds (VOCs and SVOC) were detected at concentrations that exceeded NCAC 2L Standards in ground -water samples collected from the two wells (MW-01 and RW-01) located at the former excavation area. Two VOCs were identified in samples 3 of 12 Skyland Distributing Facility — 51 Permit Application..February 6, 2004 MACTEC Project No. 6590-03-1252 collected from downgradient monitoring wells (MW-02 and MW-03) at concentrations below the NCAC 2L Standard (Figure 4). SVOCs were not detected in samples collected from the downgradient monitoring wells. These results indicate that concentrations of VOCs and SVOCs above the NCAC 2L Standards extend less than 65 feet downgradient of the source area. On January 20, 2004, NCDENR granted approval for a Corrective Action Plan, dated December 16, 2003, which recommended that low -flow air injection into vadose zone soils becombined with injection of Oxygen Release CompoundTM (ORC) into surficial ground water for remediation of soil and ground -water contamination at the site. Incident Number assigned by NCDENR-DWQ: 86033. G. HYDROGEOLOGIC DESCRIPTION SECTION (G) MUST BE ORIGINALLY SEALED AND SIGNED BY A LICENSED GEOLOGIST Provide a hydrogeologic description, soils description, and cross section of the subsurface to a depth that included the known or projected depth of contamination. The number of borings shall be sufficient to determine the following: (1) the regional geologic setting; (2) significant changes in Ethology; (3) the hydraulic conductivity of the saturated zone; (4) the depth to the mean seasonal high water table; and (5) a determination of transmissivity and specific yield of the aquifer to be used for injection (showing calculations). I have prepared the narrative contents in the following hydrogeologic descriptionfrom a review of the pertinent geologic / hydrogeologic information. The following sections describe the regional geologic conditions and the methods employed to obtain physical data that support our discussion of the local geologic and environmental conditions. 4 of 12 Skyland Distributing Facility — 51 Permit Application February 6, 2004 MACTEC Project No. 6590-03-1252 G.1 Topographic Conditions Using the 1965 U.S.G.S.

The tributary flows northwest into Lake Julian, which is located approximately 3,500 feet northwest of the site. G.2 Geology G.2.1 Regional Geology The site is located in the Blue Ridge Physiographic Province. Based on a review of the Geologic Map of North Carolina, dated 1985, the subject property is underlain by rocks consisting primarily of muscovite-biotite gneiss. The bedrock in this region is structurally complex and consists of crystalline rock that has been faulted and contorted by past tectonic movements. The rock has weathered to residual soils which form the mantle for the hillsides and hilltops. The typical residual soil profile in areas not disturbed by erosion or construction -related activities consists of clayey soils near the surface where weathering is more advanced and underlying sandy silt and silty sand. G.2.2 Site Geology On the basis of previous records related to drilling activities at the site, the following interpretation of the site geology was developed. On May 15, 2002, Altamont Environmental, Inc. advanced two soil borings and installed two ground -water monitoring wells (MW-02 and MW-03). The wells are located approximately 70 feet and 165 feet hydraulically downgradient of the source area (Figure 4). According to the Well Construction Records, soil encountered during advancement of the borings consisted of tan silty clay from ground surface to five feet below ground surface (bgs) and grey silt from five feet to thirteen feet bgs. On November 3, 2003, MACTEC advanced two exploratory hand -auger borings approximately 15 feet east of the former excavation area. Soil encountered during advancement of the hand -auger borings consisted of grey, very micaceous, sandy silt from ground surface to 10 feet bgs. On October 29, 2003, ground water was encountered at approximately 1 to 4 feet bgs in monitoring wells MW-01, MW-02, and MW-03. Copies of the well construction records for wells MW-02 and MW-03 are provided in Appendix A. HYDROGEOLOGIC INVESTIGATION The hydraulic conductivity is a constant of proportionality relating to the ease with which a fluid passes through a porous medium. Based on MACTEC's experience at sites with similar soil characteristics (i.e., micaceous sandy silts) in the Blue Ridge region, we estimate the hydraulic conductivity at the site to be approximately 2.0 to 2.5 ft/day. 5 of 12 Skyland Distributing Facility — 51 Permit Application February 6, 2004 MACTEC Project No. 6590-03-1252 In addition to hydraulic conductivity (k), the rate of groundwater movement (v) at the site is a function of hydraulic gradients (i) and the effective porosity (ne) of site soils, as indicated by the equation v = ki/ne. Based on published values for similar soils, the effective porosity of the soil at the site is estimated to be about 30 percent (Driscoll, 1986). The hydraulic conductivity of the soil estimated from previous investigations in the area is 2.0 to 2.5 feet/day. Based on the hydraulic conductivity range, a hydraulic gradient of 0.03 feet/foot (between wells MW-01 and MW-03), and an average effective porosity of 0.30, the linear velocity of ground water in soil at this site is estimated to range between 73.0 and 91.3 feet per year. G.3 Transmissivity and Specific Yield Transmissivity is the measure of the amount of water that can be transmitted horizontally by the full saturated thickness of the aquifer under a hydraulic gradient of 1. Transmissivity (7) is calculated as the product of the hydraulic conductivity (K) and the saturated thickness of the aquifer (b). In this instance, hydraulic conductivity has been estimated to range from 2.0 to 2.5 ft/day. Aquifer thickness is typically estimated by determining either the maximum vertical extent of ground -water contamination or the depth to bedrock or other impervious soil layer. However, the shallow depth (total depths of 10 to 14 feet bgs) of monitoring wells and absence of additional information regarding subsurface conditions at the site precluded direct measurement of aquifer thickness. Based on MAGI EC's experience at other sites in the area, we estimate the depth of bedrock at the site to be between 40 and 50 feet bgs. Based on a ground -water depth of 2.97 feet that was measured in well MW-01 in October 2003, the total saturated thickness of the aquifer is estimated to be between 37 and 47 feet. K = 2.0 feet/day K = 2.5 feet/day b = 37 feet b=47feet T=bK T,,,i„ = 37 ft x 2.0 ft/day = 74.0 ft2/day Lax = 47 ft x 2.5 ft/day = 117.5 ft2/day Specific yield is the ratio of the volume of water that drains from a saturated rock owing to the attraction of gravity to the total volume of the rock (Fetter, 1988). Published values of specific yield for soil types indicate that the average specific yield for silty soils is 18 %. H. MONITORING PROCEDURE Provide plans for proposed location and construction details of ground -water monitoring well network, including a schedule for sampling and analytical methods. Include any modeling/testing performed to investigate injectant's potential or susceptibility to change (biological, chemical or physical) in the subsurface. 6of12 Skyland Distributing Facility — 51 Permit Application February 6, 2004 MACTEC Project No. 6590-03-1252 A monitoring program will be initiated after the ORCTM injection event at the site to track enhanced degradation of the target compounds. Components of the monitoring program will include: Quarterly sampling and semi-annual reporting of wells MW-01 and RW-01 (source area wells) and MW-02 and MW-03 (downgradient plume -delimiting wells) during the first and last year of the corrective action program. The analytical results for the non -reporting quarters will be submitted to the Asheville Regional Office of NCDENR. • Semi-annual sampling and annual reporting of the well network described above will be conducted during year two. The analytical results for the non -reporting semi-annual events will be submitted to the Asheville Regional Office of NCDENR. • Laboratory analysis of collected ground -water samples will be performed for purgeable aromatics, including naphthalene, by EPA Method 602. During the final year of post remediation sampling, additional analyses such as EPA Method 601 (including MTBE and IPE), EPA Method 504.1 (EDB), and EPA Method 625 will be performed for site closure purposes. Each monitoring report will include a brief historical summary of the site incident, problems experienced during the reporting period, how the system is operating towards meeting the desired endpoints, if the contaminant plume is moving or changing in concentration, and recommendations to improve operations, if any. The report will also include a brief discussion of the methods utilized in obtaining samples and will include the laboratory analyses listed in a table by well identification number. The table will have a column that outlines analytical results and the North Carolina Groundwater Quality Standards. Samples exhibiting concentrations that exceed Groundwater Quality Standards will be highlighted in bold. The monitoring report will include maps that depict the following: 1. Estimated distribution of the dissolved -phase contaminant plume. A separate isopleth map for benzene will be provided. This map will display the levels of benzene concentrations in ground water with the use of inferred isopleth lines which connect points of equal concentrations. 2. Water table contour maps, with water levels shown in each well gauged, referenced to a surveyed datum. As the enhanced biodegradation of contaminants progresses, the concentrations of target compounds in the source area wells are expected to attenuate to levels below their respective State Ground -water Standards. Verification that ground -water clean-up goals have been achieved at the site will be obtained when the sampled wells exhibit compound concentrations that are below their respective State Ground -water Standards during four consecutive quarterly sampling events. 7 of 12 Skyland Distributing Facility — 51 Permit Application February 6, 2004 MACTEC Project No. 6590-03-1252 I.
