SITE CHARACTERIZATION REPORT ADDENDUM#3 KELLY'S KORNER 4006 Earlysville Road Earlysville,VA 22936 Albemarle County PC 1999-5215 Submitted to: Gregory L. Clark Valley Regional Office Department of Environmental Quality Po Box 3000 Harrisonburg, VA 22801 (540)574-7911 Prepared for: Mr. M.O. Whyte PO Box 197 Earlysville 22936 6325 Red Bird Lane Earlysville,Virginia 22936 (804)973-5570 (434)996-2765 Prepared by: Silka Environmental Services, Inc. PO Box 1283 Haymarket,Virginia 20168 (703)216-2490 November 23,2014 Kelly's Korner,PC 1999-5215 Page 2 1.0 Introduction By email dated September 11, 2014, Gregory L. Clark, DEQ case manager,requested that an SCRA#3 be completed for the Site. This SCRA#3 consisted of the installation of one additional shallow monitoring well and three deeper monitoring wells and the sampling and analysis of all the monitoring wells and a number of residential water supply wells bordering the west and north sides of Earlysville Green in the Earlysville Heights subdivision. 2.0 Monitoring Well Installation 2.1 Locations. New shallow MW-4 was proposed to evaluate the extent of the shallow plume centered on MW-2. New deep wells MW-5, MW-6, and MW-7 were proposed to evaluate the extent of the deep plume that was feeding the nearby water supply wells, i.e.,MW-5 between the source and the Church well,MW-6 between the source and Earlysville Auto Center well, and MW-7 between the source and the EWC well. The initial proposed locations of the new monitoring wells are shown on Figure 1 below. The locations of the new monitoring wells had to be coordinate with the Church due to the proposed construction of the new Church buildings that are shown in Figure 1. The location of MW-5 was set to the west of the proposed retention pond to keep the well away from construction activities. 2.2 Utility Marking. On the morning of October 151, Lyle Silka and Robert Tingley met at the Site and determined drilling locations. The locations were marked with white marking paint and flags. Pastor Scott Knight was notified of the locations. After he saw the locations, MW-7 and MW-5, Pastor Knight believed they were in areas where children would be playing and may cause a hazard. So MW-7 was moved southward to the edge of the parking lot,which moved it closer to the source and would have an improved chance of detecting contamination. MW-5 was moved as close to Earlysville Forest Drive to avoid the retention pond, which also moved MW-5 closer to the line running from the source to the Church well. The overhead power lines running through the middle of the Site also had to be avoided. Figure 2 is an aerial photo with the final monitoring well locations indicated. After the final locations were agreed upon, Miss Utility was called on October 6'h to schedule marking of the buried utilities. Lyle Silka had to recontact the marker to ensure that he marked MW-5 and MW-7 that he missed on the first go around. , , Kelly's Korner, PC 1999-5215 • Page 3 Auto WW r T ®// t ' w Deep /�',. / 6 % Chu�• ( 14 \ .� W W i5 4 y o New r4ecp MW - f r ePrh� „�F + /' ' Blew �ppip /• m ep • 1yr, / .-',.",„„1‹ MV�I , q r,R - r / le _p e.. ! `� w `M . il,/ 5 y/ • tip.'.i y'49 q t?"•L ( .^-I.�. /,.,.. dry'"`, .' r ? { \ ,t;4 n vpq 1 ,F / > New Shallow A MW-4 f C� 1 0 50 100 ft /� r > Gasoline z ele. . - Figure 1.

Final monitoring well locations as installed. 2.3 Monitoring Well Proposed Design. The deep wells were per to penetrate to the first deep water zone in the bedrock. Since the shallow groundwater zone was potentially contaminated, each deep well would have a six-inch diameter surface casing installed into the bedrock that was estimated to be at least 50 feet deep (the shallow monitoring wells, at 45 feet deep, did not encounter bedrock). The six-inch surface casing would be grouted to seal off the deep groundwater in the bedrock from the shallow groundwater. A two-inch diameter PVC monitoring well would be constructed through the six-inch casing and drilled tos a depth to penetrate the first deep groundwater-bearing zone. Two-inch screen would be set in the bottom 50 feet. Figure 3 is a generalized illustration of the deep monitoring well construction. . lly's Korner, PC 1999 -15 Page 5 Deep :ell linto}Be drock — Steelwa1 {)» } # 4 ,r Borehole roc Surface Casing / ƒ \ Be Ae »a \ i \ / Bedrock Surf 3 » { roc / % � 4 « k�de sin ° ¥ # ' A « 4.

On October 14th, CED mobilized to the Site with the hollow-stem auger drill rig and installed the two-inch MW-4 to a depth of 45 feet. Shallow groundwater was encountered at about 39 feet of depth. • On October 16111, CED installed MW-6. Drilling encountered bedrock at about 60 feet of depth, and 60 feet of six-inch surface casing was set and grouted. The four-inch borehole was drilled through the surface casing and encountered the first water-bearing zone at a depth of between 120 and 130 feet. The four-inch borehole was stopped at 140 feet, and 90 feet of two-inch PVC casing and 50 feet of two-inch PVC screen were installed. The screen was backfilled with no. 2 sand. On October 17'h, CED installed MW-7. Drilling encountered bedrock at about 60 feet of depth, and 60 feet of six-inch surface casing was set and grouted. The four-inch borehole was drilled through the surface casing and encountered the first water-bearing zone at a depth of between 120 and 130 feet. The four-inch borehole was stopped at 140 feet, and 80 feet of two-inch PVC casing and 60 feet of two-inch PVC screen were installed. The screen was backfilled with no. 2 sand. On October 21M, CED installed MW-5. Drilling encountered bedrock at about 70 feet of depth, and 70 feet of six-inch surface casing was set and grouted. The four-inch borehole was drilled through the surface casing and encountered the first water-bearing zone at a depth of between 125 and 135 feet. The four-inch borehole was stopped at 140 feet, and 90 feet of two-inch PVC casing and 50 feet of two-inch PVC screen were installed. The screen was backfilled with no. 2 sand. 2.5 Monitoring Well Surveying. With the three monitoring wells installed on a line, surveying was not completed on the first three monitoring wells installed under SCRA-2. Surveying of the top of casing(TOC) all seven monitoring wells was completed under this phase on October 23rd Table 1 shows the results of the surveying. MW-1 was set as the local datum with a TOC elevation of 639.00 feet above mean sea level estimated from the topo map. , Kelly's Korner, PC 1999-5215 Page 7 Table 1.

No free-phase petroleum was found in the monitoring wells. The depths to groundwater are listed in Table 1 above. Figure 4 is a groundwater elevation contour map for the shallow monitoring wells. It also shows the groundwater elevations in the deep wells which are not contoured since they do not appear to be connected. 3.1 Range in Shallow Groundwater Elevation. The shallow groundwater elevation ranged from 28.88 to 30.61 feet and rose by 0.99 feet in MW-1, but fell by a third of a foot in MW-2 and MW-3 since April. 3.2 Shallow Groundwater Gradient. The shallow groundwater gradient in the horizontal direction is estimated from MW-2 to MW-4 as 0.0033, i.e.,the difference in groundwater elevation between MW-2 and MW-4 divided by the 60 foot distance between the two wells. The 2001 water levels indicated a shallow groundwater flow direction toward the north. The current levels appear to show a slight groundwater mount centered around MW-2. The higher level in MW-2 also appeared in the April measurements. This mound would explain the spreading out of the contaminated groundwater in the shallow zone, especially to MW-1. 3.3 Range in Deep Groundwater Elevation. The deep groundwater in the bedrock had elevations ranging from 29.20 to 30.34 feet.

Groundwater elevations and shallow groundwater elevation contours for this event. 3.4 Deep Groundwater Gradient. The deep groundwater gradient in the horizontal direction is estimated from the difference between the 606.0-foot contour to the 604.4-foot contour, separated by a horizontal distance of 224 feet. Thus, 1.6 feet divided by 224 feet gives a gradient of 0.0071. Flow direction in the bedrock is indicated to the northwest. This happens to align with the dominant alignment for quartz veins and the secondary alignment for fractures. 3.5 Vertical Groundwater Ggradient. The vertical gradient from the shallow to the deep monitoring wells is estimated from the shallow MW-3 and deep MW-6 that are relatively close. MW-3 is at 607.07 feet,while MW-6 is at 604.34 feet, a difference of almost three feet (2.69 feet) in the downward direction. This means that the shallow groundwater should be migrating vertically downward under a gradient of approximately 2.69 feet/50.77 feet, or 0.05. The numerator is the difference in groundwater levels in MW-3 and MW-6, and the denominator is the difference between the bottom of the screen in MW-3 and the top of the screen in MW-6. , Kelly's Korner,PC 1999-5215 Page 9 The vertical gradient compared to the horizontal gradients in the shallow groundwater in the saprolite versus deep groundwater in the fractured bedrock is illustrated in Figure 5. These are directional vectors with length indicating the magnitude of the gradient. The gradient is one of the inputs into the groundwater velocity calculation: Velocity =Permeability x Gradient/Effective Porosity The gradient vectors in Figure 5 are the direction of groundwater movement. Going deeper,the vectors will become flatter, and then begin to turn back up toward the North Fork Rivanna River where the groundwater discharges. The natural, downward gradient is accentuated by the presence of the numerous water supply wells that are pumping from anywhere between 100 and 300 feet deep.

This is an idealized model that does not include fracture flow in the bedrock. However, flow through a single fracture plane that extends from the saprolite to some depth into the bedrock would have a similar groundwater flow pattern. The potentially closest discharge points for groundwater are Fishing Creek 4,400 feet to the southwest at an elevation of 495 feet and Jacobs Creek 8,000 feet to the northeast at an elevation of 440 feet. Figure 6 illustrates the importance of the downward gradient for sites located on the tops of ridges, and is referred to again in the following section on the results of the groundwater analyses.

The 2000 SCR reported the results of a slug-recovery aquifer test conducted on the old MW-1. The hydraulic conductivity of the saprolite was estimated to be on the order of 0.06 feet per day. The data in 2000 indicated a hydraulic gradient across the Site was 0.005. The effective porosity of the saprolite was estimated to be on 0.1. The groundwater velocity was estimated to be on the order of 0.003 feet per day, or 1.1 feet per year,using the following equation: V = K►/ne . , Kelly's Korner,PC 1999-5215 Page 11 where v =the groundwater seepage velocity, K=hydraulic conductivity (0.06 feet per day), / =hydraulic gradient(0.005 feet per foot), and ne= effective porosity (0.1, dimensionless). 4.2 Permeability Estimated by Bear Drain Model. The two-drain model (Bear, 1979, Hydraulics of Groundwater Flow p. 180) estimates the average aquifer permeability assuming a homogeneous aquifer with uniform recharge and discharge at each end to a constant elevation discharge point(drain or stream). Previously, an average recharge rate of 7.0 inches has been used for Virginia. However,monitoring of streamflow has shown that base flow in the North Fork Rivanna River has decreased significantly since 2004. A new estimate for recharge is calculated first. 4.2.1 Recharge Estimate. The drainage basin of the North Fork Rivanna River above the USGS streamflow station near Earlysville covers 108 square miles (located at Dickerson Road bridge). Baseflow in the river is due to groundwater discharging from the bedrock/saprolite. Baseflow can be estimated from the streamflow in the late summer and early fall when runoff is lowest due to high ET and low rainfall. Figure 7 is a graph of streamflow at the Earlysville gaging station along with the accumulated departure of monthly precipitation from the long-term mean(1948-2007). 20 _ 1000 - N _ G - au __ • D - .4 d u g A a -20 — _ _ Li E 1 0• 40 — ! a a Mean=16.3CFS _ 10 g. , _- g Am -60 -v Streamfow — O Cumulative - iDeparture From Mean - E g• -BO I I I I I I I 11 I 1 Deo04 Deo-06 Dec-06 Dec07 Dec-08 Dec-09 Dec-10 Dec-11 Dec-12 Dec13 Dec-14 Dec-16 Figure 7. Graph of streamflow in the North Fork Rivanna River at the Earlysville gaging since 2004 with a comparison to the accumulated departure of monthly precipitation from the long- term mean (1948-2007). Kelly's Korner,PC 1999-5215 Page 12 Streamflow in these dry months can be assumed to be due to baseflow. This also assumes that change in storage within the aquifer is minimal from year to year. The streamflow in these dry months can be used to estimate the recharge rate over the basin. Table 2 shows the lowest monthly mean streamflow from Figure 7. The lowest monthly streamflow occurred in August or September, except one year in July and one year in November. The baseflow in the North Fork has averaged 16.3 cfs over the last 11 years. Table 2. Estimating baseflow from lowest monthly streamflow Year Month Mean CFS 2004 8 29.7 2005 9 13.4 2006 8 6.4 2007 9 10.4 2008 9 28.5 2009 9 13.2 2010 8 4.1: 2011 •8 9.5 2012 7 • 16.3 2013 9 20.2 2014 9 10.3 Mean 14.7 Using the area of the drainage basin of the North Fork and the total cubic feet of flow based on the 14.7 cfs monthly mean flow from Table 2,the equivalent precipitation required to produce • that baseflow all year long would be 1.85 inches. Thus,the annual recharge is estimated to be 1.85 inches. To obtain 7.0 inches of recharge, the baseflow would have to be 56 cfs. This analysis indicates that a more accurate average recharge rate over the last eleven years would be 1.85 inches,not 7.0 inches. I have not gone examined the daily flows in each of the months in Table 2 for extreme values when a large storm produces a brief surge in runoff. For example, from September 27 to October 6, 2013,the mean streamflow was only 13.5 cfs, whereas the inclusion of storm runoff bumps the average in table 2 up to 20.2 cfs. The 1.85 cfs recharge estimate may be on the high end. Kelly's Korner, PC 1999-5215 • Page 13 4.2.2 Drain Model. Figure 8 is the graph produced by the Bear drain model (see attached printout) for a recharge rate of 1.85 and a constant watertable elevation in Fishing Creek 4,400 feet to the southwest of 495 feet and Jacobs Creek 8,000 feet to the northeast of 440 feet. The permeability that produces a match of the groundwater elevation at the Site of 600 feet is 0.11 feet per day. This estimate is not much greater than the 0.06 ft/d. 650 Southwest Northeast _ Fishing Creek Jacobs Branch 600 a 550 O d 600 W _ 450 400 ili lilillilli iililillilililili llililillili III • II1O, 111 lilililiI li O Q 8 N 8 8 g 8 N 8 8 a- N 8 8 v 8 N 8 O O W N t00 8 VO' GOD N f0 O C r r N N N p) C') V Q V I) )0 CO (0 CO t- r- CO CD W 0 O)' O O O r r N N Distance (Feet) Figure 8. Graph of the Bear drain model with the groundwater elevations fixed at the two edges where discharge occurs to the nearest perennial streams. The permeability is adjusted to obtain a match of the curve to the observed groundwater elevation at the Site. Note that the drain model places the groundwater flow at the Site to the southwest, not the northeast as found in the shallow wells. Nothing is simple in the Blue Ridge. 4.3 Groundwater Flow Velocity. In 2000, the groundwater velocity was estimated to be on the order of 0.003 feet per day, or 1.1 feet per year,using the following equation: v = Kline where v =the groundwater seepage velocity, 0.003 feet per day K=hydraulic conductivity (0.06 feet per day), / =hydraulic gradient(0.005 feet per foot), and tie= effective porosity (0.1, dimensionless). Kelly's Komer,,PC 1999-5215 Page 14 The new permeability estimate of 0.11 feet per day is probably more reflective of the bedrock aquifer than the saprolite. The horizontal gradient was estimated to be 0.0071. The effective porosity is lower in the bedrock and is estimated to be 0.01 at this time. The horizontal groundwater velocity in the bedrock is estimated to be 0.08 feet per day, or 29 feet per year, as follows. v= Ki/ne where v =the groundwater seepage velocity, 0.08 feet per day - K=hydraulic conductivity (0.11 feet per day), / =hydraulic gradient(0.0071 feet per foot),,and ne=effective porosity (0.01, dimensionless). The vertical velocity is estimated from the vertical gradient of 0.05. Using the bedrock permeability of 0.11 feet per day,the vertical velocity is estimated to be 0.55 feet per day, or 200 feet per year. 5.0 Water Supply Well Sampling and Analysis The parcel ID's,names and address of the water wells sampled during this SCRA#3 are listed below.

The monitoring wells were sampled after bailing approximately three volumes of water from each well. Each groundwater sample was collected in two 40-milliliter vials and shipped to Maryland Spectral Services for analysis of MBTEX by EPA Method 8021B. The lab reports are attached. The following table presents results for the monitoring wells sampled to date, including the previous sample analyses. Table 1.

Only MTBE appears to be migrating beyond the immediate vicinity of the former Kelly's Korner store.

A comparison can be made between the groundwater velocities estimated in Section 4.3 and estimates of the arrival times of MTBE at various wells. The velocity in the vertical downward direction has a maximum estimated velocity of 200 feet per year. However the flow lines may become shallower as groundwater moves away from the groundwater divide (assumed to be just south of the former Kelly's Corner store. The minimum groundwater velocity in the bedrock is estimated to be the horizontal velocity of 29 feet per year In the previous report, SCRA-2, it was estimated that the lowest velocity to Mawyer's well was 690 feet divided by 34 years=20 feet per year. The Auto Center well became contaminated between April 2001 and April 2014. The Auto Center well is estimated to be 485 feet from the source. This would produce a range for groundwater velocity of between 485 feet divided by 21 years=23 feet per year, and 485 feet divided by 34 years= 14 feet per year. The Church well became contaminated between April 2001 and July 2013. The Church well is estimated to be 460 feet from the source. This would produce a range in groundwater velocity of between 460 feet divided by 21 years=22 feet per year, and 460 feet divided by 33 years= 14 feet per year. These average groundwater velocity estimates along the flow path from the release to the wells of between 14 and 23 feet per year are similar to the estimated low velocity of 29 feet per year. It also is puzzling that the gasoline contamination from the UST system never appears to have been pulled into the Kelly's Korner water well that is within 50 feet of the release. 8.0 Future Migration Whether a water well becomes contaminated or not depends on whether the well intersects a fracture or quartz vein connected to contaminated groundwater that will be drawn into the well and be produced by the well with a detectable concentration of MTBE after dilution in the well. The distribution and source of MTBE-contaminated groundwater is important. It is not known whether the MTBE plume is still behaving similar to a plume with a constant source of MTBE, , Kelly's Korner,PC 1999-5215 • Page 20 or if the plume is more like a slug release moving through the groundwater and will decrease after peak concentration passes by. It appears that sufficient time has elapsed since groundwater contamination began for water wells to become contaminated, if they were to ever be contaminated at all, in the direction of the Church well that has not exceeded 1.0 µg/1 MTBE. The next wells beyond the Church well are another couple hundred feet to the northeast. It does not appear that detectable concentrations would appear beyond the Church well. To the northwest,the Earlysville Auto Center well has had up to 4.7 µg/1 MTBE, and the Mawyer well had 2.2 µg/1.MTBE. Figure 11 on the following page are graphs presented in the previous report, SCRA-2,that shows the graph of MTBE concentration verses distance. Somewhere between the former Kelly's Korner store and the Auto Center well, MTBE concentrations in the hundreds should be present. It appears that either the deep monitoring wells are not deep enough, or are not intersecting the fractures or quartz veins that are transporting the contaminated groundwater. 9.0 Recommendations If the DEQ believes the MTBE concentrations require replacement wells, I believe that a location to the northwest of MW-7 may provide a location that would not become contaminated. However, if that were proposed, I would recommend a deeper monitoring well at the MW-7 location to help confirm the status of groundwater deeper in the bedrock. Monitoring over the next year may provide data to.gain confidence in future predictions. At this time,the limited data appear to indicate that the MTBE plume is approximately at steady state. However,the Church well has not been used in a couple years. When the Church begins to use it, MTBE may increase. 4/4. /Z. .1•200C..- Lyle R.

The following compounds were detected. Chloroform 1.23 ug/l. (microgram per liter or parts per billion) This is due to chlorination of the well. This is not an issue. Methyl tert-butyl ether (MTBE) 0.98 ug/1. This is an additive to gasoline and may be related to the MTBE plume that I discussed in the Phase I report that originated at the former Kelly's Korner store. EPA has not set a national standard for MTBE, although some states have set their own limits. Currently,Virginia has a"zero tolerance" policy regarding petroleum in drinking water. Virginia currently is assessing whether they will discard the zero tolerance policy and close cases where the well water has some concentration of MTBE, say 10 ug/l. EPA issued a Drinking Water Advisory that states concentrations of MTBE in the range of 20 to 40 ppb of water or below will probably not cause unpleasant taste and odor for most people,recognizing that human sensitivity to taste and odor varies widely. The advisory is a guidance document that recommends keeping concentrations below that range. EPA also reviewed the available information on health effects in 1997 and stated that there is little likelihood that MTBE concentrations between 20 and 40 ppb in drinking water would cause negative health effects. (http://www.epa.gov/mtbe/water.htm) The detected level of MTBE is essentially 1.0 ug/1. This is very low, and in and of itself, is no threat to health. However,the water well probably has not been pumped for a while,since Earlysville Green has been vacant. The well should be retested after the well has been in regular use to determine if a higher concentration is pulled in to the well. I recommend that this be reported to the Department of Environmental Quality and request that the DEQ require additional monitoring to evaluate the risk of MTBE to the well water. This should cause DEQ to reopen the Kelly's Korner case and means that DEQ would pay for any investigation they may require. This would not cost Mr. Whyte anything either,since I believe he already met his financial responsibility (like an insurance deductible). It would be appropriate for DEQ to delineate the MTBE plume that was shown to be migrating on to Earlysville-Green_from-Kelly's-Korner and assess therisk-to-the well - water. Delineation of the plume would require the installation of several monitoring wells to allow sampling of the groundwater. r Please do not hesitate to contact me if you have any questions.

(JAS)has completed a Phase I Environmental Site Assessment(ESA) of the property located at 607 Earlysville Green,Earlysville,Virginia, County of Albemarle, (hereafter, the Site) at the request of Scott Knight, representing Rivanna Community Church. This ESA was conducted to satisfy the"all appropriate inquiries"standard of the 2002 Brownfields Amendments to the Comprehensive Environmental Response, Compensation and Liability Act(CERCLA). Any exceptions to, or deletions from,this practice are described in Section 6.0 of this report. JAS believes that it has conducted all appropriate inquiry into the current and historical uses and ownership of the subject property, consistent with good commercial and customary practice and in general accordance with ASTM Practice E 1527-05, in an effort to identify evidence of any existing, suspect, or potential recognized environmental conditions, as defined in ASTM Practice E1527-05, that may impose an environmental liability to the subject Site. After conducting a visual site inspection and review of historical information, the assessment has revealed a Historic Recognized Environmental Condition in connection with the former Kelly's Korner gasoline release that abutted the Site. While the DEQ closed the Kelly's Korner case in 2001, a potential MTBE plume existed that could have migrated onto the Site. Since the DEQ did not fully determine the extent of the MTBE plume, it was recommended that a new well water sample be collected to ensure that the well water remains clean after the 12 years since the DEQ closed the case. If the well water is free of detectable contamination,then it will be concluded that the release from the former Kelly's Komer has not impacted the well water quality. Considering the time elapsed since the release and case closure, if the onsite well water has remained free of contamination,then it is not considered a recognized environmental condition. • We will await results of the lab analysis of the well watersample collected on July 10, 2013. We declare that, to the best of our professional knowledge and belief,we meet the definition of Environmental Professional as defined in 40 CFR Part 312.10. We have the specific qualifications based on education,training, and experience to assess a property of the nature, history, and setting of the subject property. We have performed the all appropriate inquiries in conformance with the standards and practices set forth in 40 CFR Part 312. Ly R. Silka Virginia Certified Professional Geologist No. 972 _ _ _JA . Jeffre . i er Virginia Certified Professional Geologist No. 201 , Jeffrey A. Sitler Environmental Services,Inc. Page iv 1.0 INTRODUCTION 1.1 Purpose • Jeffrey A. Sitler Environmental Services, Inc. (JAS) has completed a Phase I Environmental Site Assessment(ESA) of the property located at 607 Earlysville Green, Earlysville, Virginia, County' of Albemarle, (hereafter, the Site) at the request of Scott Knight, representing Rivanna Community Church. • The purpose of this Phase I ESA was to conduct"all appropriate inquiries" info the current and previous uses and ownership of the subject property, consistent with good commercial and customary practice and in general accordance with'ASTM Practice E1527-05 in an effort to identify Recognized Environmental Conditions associated with the subject Site. The"all appropriate inquiries" standard was developed by the US Environmental Protection Agency pursuant to the 2002 Brownfields Amendments to the Comprehensive Environmental Response, Compensation and Liability Act(CERCLA). • According to ASTM Practice E1527-05, a Recognized Environmental Condition,is defined as the presence or likely presence of any hazardous substances or petroleum products'on a property under conditions that indicated an existing release, a past release, or a material threat of a release • of any hazardous substance or petroleum products into'structures on the property or into the ground,groundwater, or surface water of the property. ASTM further states that the term is not intended'to include de miriimis conditions that generally do not present a material risk of harm to public health or the environment and that generally would not be the subject of an enforcement " action if brought to the attention.of appropriate governmental agencies. 1.2 Reliance Statement • Findings and conclusions presented herein are based upon JAS' visual observations of the condition'of the Site on the specific date(s) of investigation and background information obtained from various sources listed. Background research, inquiries, and the visual inspection of the Site was performed by Lyle R. Silica,Virginia Certified Professional Geologists with JAS (see brief resume in Section 7.0 at the end of this report). This report was prepared for the benefit of the Client, and the contents can be relied upon by the Client, its employees and affiliates, its lender, , and its counsel and consultants. • 1.3 Scope of Work JAS conducted the ESA in general accordance with ASTM Practice El 527-05. No environmental site assessment can wholly eliminate uncertainty regarding the potential for recognized environmental conditions in connection with a property. The performance of the Phase I ESA is intended to reduce but not eliminate uncertainty regarding the existence of , recognized environmental conditions. hi developing their standards, ASTM recognized that this practice has reasonable limits of time and cost. Research into historical documentation is necessarily limited to what is reasonably available. With this in.mind,_the..Phase-LESA.consists of the following: Jeffrey A.Sitler Environmental,Services,Inc. „ Page 1 I. Identify"all obvious uses" of the Site from the present back to the date of the first development of the Site, or back to 1940, whichever is earlier. This task requires reviewing only as many of the "standard historical sources" as are necessary and both reasonably ascertainable and likely to be useful. The "standard historical sources" may include,but are not limited to, current and historical aerial and other photographs, Sanborn Fire Insurance maps, land use records, previous investigations and reports, and land ownership records. 2. Research and review information pertaining to the previous uses of the Site and surrounding properties. This may be accomplished by interviewing current or previous owners, tenants,neighbors, municipal and other government officials, and other knowledgeable parties. 3. Research and review reasonably available topographic maps, soil, and hydrogeologic information. This information will be used to evaluate the soil and geologic conditions on the subject property, estimate the directions of surface and groundwater flow, and identify potential sources and/or receptors of potential groundwater contamination. 4. Conduct a regulatory screening under the Freedom of Information Act and according to ASTM Standards to determine if information concerning the subject properties and/or neighboring properties exists at the local, State and/or Federal level. This search will include,but not be limited to, a review of the Virginia Department of Environmental Quality(DEQ) registered UST, Leaking Underground Storage Tank(LUST), and Emergency Response Notification System (ERNS) databases; and the U.S. Environmental Protection Agency's (EPA) Comprehensive Environmental Response, Compensation, and Liability Information System(CERCLIS), Resource Conservation and Recovery Information System(RCRIS), and National Priority List(NPL) databases. 5. Perform a visual on-site inspection of the subject Site, including any structures on the Site, and adjacent properties (where accessible) for evidence of surface dumping and/or environmental misuse. This includes,but is not limited to, any abnormalities such as odors, seeps, sheens, stained soil or pavement, stressed vegetation or lack of vegetation, suspicious fill areas, or unusual depressions, escarpments, or grades. Visually inspect for potential sources of petroleum-related or hazardous substances contamination. This includes, but is not limited to, fill pipes, vent pipes, or other signs indicative of USTs; electrical transformers or equipment which may contain polychlorinated biphenyl compounds (PCBs); and note type of heat, utilities, i.e., electricity,telephone, water, and sanitary, such as septic tank and field or municipal sanitary sewer. Assessment of non-scope concerns, i.e., asbestos containing materials (ACM),urea- formaldehyde insulation, radon, lead-based paint, lead in drinking water, and wetlands, is not required in the Phase I ESA to be in compliance with ASTM E1527-05. Therefore this Phase I --ESA-technical approach-does-not-include-the-non-scope-eoncems. The-Client-did-not-request- JAS to address any non-scope concerns. Jeffrey A. Sitler Environmental Services,Inc. Page 2 1.4 Previous Reports No previous environmental reports have been identified for the subject Site. 2.0 SITE INVESTIGATION The following subsections describe the Site location, hydrogeology, and land use, as determine through review of historical documents, hydrogeologic publications, and aerial photographs and discussions with persons knowledgeable about the Site. 2.1 Site Location and Legal Description The Site is located north of Earlysville Road and east of Earlysville Forest Drive as shown on Figure 1, and has an area of approximately four acres. The Site is owned by M.O. and Mary G. Whyte. Figure 2 is a June 2013 plat for the Site prepared by Blackwell Engineering. 2.2 Site Structures and Improvements The Site has a one-story brick office and restaurant building constructed on a concrete slab. The building was constructed circa mid-1970s. There are two paved parking lots on the Site. The Site has electric and telephone service via overhead lines, an onsite drilled water well, and a septic system. The building is heated with electric heat pumps. 2.3 Current Land Use on the Site The Site currently is vacant. 2.4 Current Land Use on Abutting Land As shown on Figure 3, the Site is bounded on the east by Earlysville Forest Drive and a post office and offices. To the south is a vacant store, small auto repair shop, and single-family home. To the west, the Site is abutted by the Earlysville Auto Center. To the north, the abutting land consists of a residential development. 2.5 Information Regarding Environmental Liens or Specialized Knowledge or Experience Scott Knight and Ellen Phillips Siroka, with the Client,provided historical information on the Site. There are no known environmental liens. Lyle Silka,author of this ESA report,has had knowledge of the Site since 1999 when he conducted subsurface investigations on the Site and at the former Kelly's Komer store. Mr. Silica had not developed any information regarding environmental concerns on the Site during those earlier investigations. Jeffrey A. Sitter Environmental Services,Inc.

' • Jeffrey A.Sider Environmental Services,Inc. Page 6 2.6 Site Physical Setting Geology. The Site is within the Blue Ridge Geological Province which was developed on metamorphic rocks of primarily gneiss and schist and covers the Commonwealth of Virginia from approximately US Route 15 on the west side to Interstate 95 on the eastern side. As shown in Figure 4, the bedrock underlying the Site is the Middle Proterozoic porphyroblastic biotite-plagioclase augen gneiss ("Ybg"), believed to be a metamorphosed igneous intrusion.' The gneiss has been radiometrically dated at slightly more than one-billion years old. Soil. Overlying the bedrock is saprolite, or weathered bedrock, that grades from nearly unweathered bedrock at depth up to completely weathered soil consisting of clay and silt at the surface. The soil at the surface is a reddish-brown, clay silt loam, changing to a reddish-brown silt below ten feet, then to a yellowish-brown micaceous silt below a depth of 20 feet. The saprolite contains relict fractures and quartz veins. Topography. As shown on Figure 5, the topography of the Site is near the local elevation high. The land surface within the Site is relatively flat with an elevation of approximately 635±5 feet above mean sea level. From.the shops on the Site, the land slopes gently toward the west. Surface Water. There is no perennial surface water, springs, or seeps on the Site of abutting properties. The Site has no distinct surface water drainage channels or ditches. Storm runs off the Site essentially as sheet flow or small rivulets and across the paved areas into drainage at the northwest corner of the Site that contains a large stormwater retention basin or"dry pond." Groundwater. Groundwater flow in the humid east generally follows the topographic slope. As shown on Figure 5, groundwater flow is across the Site toward the northwest. Groundwater flow on surrounding lands is radially away from the Site.

Sitler Environmental Services,Inc, Page 9 3.0 RECORDS REVIEW Sources of information on the historical land use of the Site and potential historical environmental conditions at the Site were obtained from a review of historical aerial photographs,title search results, and regulatory database searches. 3.1 General Historical Land Use Albemarle County was first settled in 1734 and was part of Goochland County until 1744. The first courthouse was built in 1745 near Scottsville. In 1762,the courthouse was moved to a location near the Rivanna River where Charlottesville was established in that same year. The county has been primarily agricultural throughout its history. Thomas Jefferson founded the University of Virginia in 1819 on the western edge of Charlottesville. During the 1800's textile mills existed in the central part of Charlottesville, and railroads were constructed in the mid- 1800's. Since the first settlers migrated into the county, the rural land has been used primarily for timber resources, and as pasture and hay fields for raising horses and cattle. Most of the upland woodlands in the county were cut and cleared for pasture at various times prior to the early 1900's. Continued cutting of second-and third-growth woodland has occurred more recently as part of the urbanization and development. According to Ellen Phillips Siroka(email dated July 3, 2013), the Site had a post office in the 60's (601 Earlysville Green) and subsequent offices were added over time to complete the four unit commercial block. A beauty parlor was added in the 70's, a dental office in the 80's, and a pizza parlor and coffee house in the last unit built in the 90's. The adjoining property was Whyte's Grocery which is now owned by Roger Perkins as the Earlysville Auto Center for automobile and small truck repair. 3.2 Historical Aerial Photography, Topographic Maps, and Sanborn Maps JAS inspected historical aerial photographs of the Site taken in 1937, 1957, 1963, 1966, 1974, 1980, 1990, 1996, 2000, 2002,2003, 2005, 2007, 2009, 2010, and 2011. These aerial photographs were reviewed'by JAS for evidence of historical land use iii the general vicinity of the Site. No Sanborn fire insurance maps are available for the Site. The fmdings of the review of the historical aerial photographs are discussed in the following paragraphs. Jefrey.A.Sitler Environmental Services,Inc. Page 10 1937 Aerial Photograph. In 1937, the western half of the Site was undeveloped field. The eastern half of the Site probably contained a farmstead with a house and several out buildings. A small orchard was in the northeast corner. The abutting land was undeveloped. While the county lists Kelly's Korner store(southwest corner of the Earlysville Road-Reas Ford Road intersection) as being constructed in 1937, it was not present at the time of this photograph. There is no evidence in this map of recognized environmental conditions at the Site or on the abutting properties. a Y & t— bit so/J. • s 4i Figure 6. Enlargement of the 1937 aerial photograph. Jeffrey A.Sitler Environmental Services,Inc. Page 11 1957 Aerial Photograph. By 1957,the western half of the Site appears to have been fallow pasture. The farmstead on the eastern half appears to have been removed. Kelly's Korner store is visible across Earlysville Road from the Site. There is no evidence in this map of recognized environmental conditions at the Site or on the abutting properties. 4 rItifR I �.. Figure 7. Enlargement of a portion of the 1957 Sanborn Map. Jeffrey A.Sitler Environmental Services,Inc. Page 12 ICI 1963 Aerial Photograph. By1963, a small structure had been built in the middleof the Site. There may have been one or more small structures at the rear of the Site. South of the Site,the small auto repair shop had been built on the west side of Kelly's Komer store. The residence behind the store is visible. The residence west of Kelly's Korner also is visible. There is no evidence in this map of recognized environmental conditions at the Site or on the abutting properties. X E t • jr 4#' ‘,, 41, Figure 8. Enlargement of a portion of the 1963 Sanborn Map. Jeffrey A. Sitler Environmental Services,Inc. Page 13 1966 Aerial Photograph. The Site may have had additional structures built by 1966 towards the rear of the property. The county real estate data indicates the shops of Earlysville Green were constructed in 1965. This photo does not appear to support that date. The abutting land use did not change from the 1963 photo. There is no evidence in this map of recognized environmental conditions at the Site or on the abutting properties. 5 3rG k is ya lt . r 444.41 Air Figure 9. Enlargement of the 1966 aerial photograph. Jeffrey A. Sitler Environmental Services,Inc. Page 14 1974 Aerial Photograph. The Site was undergoing land development at this time. Large areas had been cleared of vegetation. Looking ahead to the next photograph from 1980, construction of the shops may have begun circa 1974, since the shops are present in 1980. Whyte's grocery store does not appear until the 1990 photo. Residential development to the northwest of the Site had begun by this date. There is no evidence in this map of recognized environmental conditions at the Site or on the abutting properties. v u .�lsz,r a . ?v r N'R } as • • Ewa ``., s "vim- Figure 10.

This conforms with the county real estate information that the store was built in 1985. The stormwater runoff retention"dry pond"had been constructed in the northern corner of the Site. The office buildings southeast of the Site had been constructed. There is no evidence in this map of recognized environmental conditions at the Site or on the abutting properties. • Figure 12.

Enlargement of the 2011 aerial photograph. Jeffrey A. Sider Environmental Services,Inc. Page 27 In summary, JAS did not observe any indications of environmental misuse in the historical photographs. No industrial or other commercial activities or other environmentally compromising activities are indicated in the historical aerial photographs to have been conducted on the Site or abutting properties for the period of review other than those already discussed. The immediately adjacent properties do not appear to have had any other activities or uses that have not already been identified. 3.3 Title Search Information The past ownership history was not provided to JAS by the Client. Based on Albemarle County real estate data, the Site was acquired by M.O. and Mary G. Whyte in 1985. Roger W. Perkins purchased the former grocery store in 2012. It is JAS' opinion that the Site history, as portrayed by the extensive historical aerial photographic record, and limited ownership information, does not indicate a land use history with a potential environmental issue or consideration. 3.4 Regulatory Database Search JAS performed a review of Federal and State agency databases to determine whether information exists concerning.the subject property and/or adjacent properties which may indicate potential current environmental liability. JAS researched the US Environmental Protection Agency databases for the presence of facilities with toxic emissions to air and discharges to water, emergency spill incidents, Superfund sites, Brownfields cleanups,permitted hazardous waste sites, and toxic releases to land? Figure 23 is an enlargement of the EPA map showing the database search results for the vicinity of the Site. There are no EPA registered facilities or site of remediation cases within three-fours mile of the Site. The search of the DEQ databases did not reveal any Virginia Voluntary Remediation Program (VRP) sites or solid waste facilities within a mile of the Site. The solid waste facilities in the database include: Construction demolition landfill Miscellaneous landfill Energy recovery, such as coal mines Inert landfill Material recovery, such as quarries Sanitary landfill Compost facility Transfer station Industrial landfill Medical waste facility Figure 24 shows the registered petroleum tanks and petroleum releases in the vicinity of the Site. Only one state case was identified that was in a location that could potentially impact the Site: the former.Kelly's Korner across Earlysville Road from the Site. Kelly's Komer had a gasoline release in 1999 that is discussed below. No other registered tanks or petroleum cases were in a location that could potentially affect the Site. 2 http://www.epa.gov/myenv/MyMap.html?minx=78.49118&miny=38.07512&maxi=78.46736& maxy=38.08374&ve=15,38.07942,-78.47927&cLat=&cLon=&pSearch=2210 Williamsburg Rd, Charlottesville,VA 22901&players= Jeffrey A.

Kelly's Korner Gasoline Release The store across the highway to the south, formerly called"Kelly's Korner," operated as a gas ' station and hardware store from the early 1970's until it closed in 1995. Kelly's Komer was Jeffrey A. Sitler Environmental Services,Inc. Page 30 owned by M.O. Whyte. Figure 38,below, is a photograph of the former Kelly's Korner store that had three gasoline underground storage tanks (USTs). The USTs were removed on May 20, 1999. Gasoline was found to have leaked from the USTs. The release was reported to the Department of Environmental Quality(DEQ), and DEQ assigned the release Pollution Case# 1999-5215. Since the soil under the USTs did not have sufficient gasoline contamination, the DEQ did not require removal of soil from under the USTs. However,the DEQ did require that soil borings and monitoring wells be installed to determine the extent of groundwater contamination. The only contaminant found in the groundwater was an additive to gasoline called MTBE(methyl tertiary butyl ether). It has a very low toxicity to humans. EPA has not established a maximum concentration for MTBE in drinking water. DEQ makes their decisions as to what investigations and remediation will be required on the basis of risk assessment. Jeffrey A. Sitler oversaw the UST removal,while Lyle R. Silka oversaw the subsequent groundwater investigations. Monitoring wells (MW) were installed in front of Kelly's Korner and one, "MW-4,"was installed in the rear of the gravel parking lot east of the shops at Earlysville Green. The cover for MW-4 is still visible in the gravel parking lot. Between February 2000 and April 2001, five quarterly sampling events were completed by Mr. Silka as required by DEQ. Well water samples were collected from the Earlysville Green water well that is in the NE corner of the field,Whyte's grocery store well on the west side of the store, and the two water wells next to the Kelly's Komer property. Groundwater samples also were collected from the four MWs for each of the five quarterly sampling events. All of the water wells remained free of detectable contamination throughout the five quarterly sampling events. Groundwater from MW-2 that was next to the old pump island in front of Kelly's Komer had MTBE at 2,930 parts per billion. Figure 25 presents a map from April 2001 monitoring event showing the water well and MW locations and the MTBE concentrations in the shallow groundwater. The estimated MTBE plume (a guess) would head toward the Earlysville Green shops. However, DEQ did not require confirmation of the extent of the MTBE plume on the Earlysville Green property. DEQ determined that, even if the MTBE in the groundwater had migrated across the road and under the Earlysville Green shops,the potential risk to humans was insignificant. The water wells were free of detectable contamination, and MTBE has a very low toxicity. Therefore, DEQ decided to close the case with no further investigation. The potential MTBE contamination that may be under the Site does not present a health risk unless it gets into the well water. Since the onsite water well is not believed to be down gradient, MTBE should not get pulled into the.water well based on the previous investigations. If gasoline contamination was found in the well water, DEQ would reopen the M.O. Whyte case, and DEQ would pay for any further investigations or new water well through the"Virginia Petroleum Storage Tank Fund." The Church would not pay for-anything. Jeffrey A.

Page 32 On July 10, 2013, Brian Silka collected a well water sample from the former restaurant for analysis of volatile organics by EPA Method 524.2 for drinking water. The results of the lab analysis will be provided in a separate letter. 4.0 SITE RECONNAISSANCE On Monday, July.8, 2013,Lyle R. Silka with JAS visited the Site and completed a visual inspection of the Site and abutting properties. Figures 26 through 46 present photographs of various views of the Site. • 4.1 General Observations There was no visible evidence of spills, seeps, stained soil, stained pavement, stressed vegetation, or other indicators of potential past spills or releases of potential contaminants on the Site. The abutting properties do not have any visible evidence of potential past spills or releases of potential contaminants. 4.2 Hazardous Substances in Connection with Identified Uses No current uses at the Site would generate hazardous materials or that would fall under regulatory permit programs. During the visual inspection,there was no visible evidence of chemical storage or usage at the Site. • 4.3 Hazardous Substance Containers and Unidentified Substance Containers No hazardous substance containers or unidentified substance containers were observed at the Site. 4.4 Petroleum Storage Tanks There were no above ground or underground petroleum storage tanks observed at the Site. There were no visible fill or vent pipes related to underground petroleum storage tanks. 4.5 Indications of PCBs There are no visible sources of potential PCB containing materials on the Site 4.6 Indications of Solid Waste Disposal There is no visible evidence of significant solid waste disposal at the Site or adjacent to the Site. 4.7 Site Water Supply The water supply for the Site is the drilled water well located in the northeast corner of the field, _shownin_the-photograph in Figure30-below. This well-is-not-down gradient-of the gasoline release from former Kelly's-Korner gas station and was found to have been free of detectable contamination in five analyses from 2000 and 2001. A new sample was collected from the water well on July 10,,2013 for lab analysis. The results will be provided in a separate letter report. • Jeffrey A.Sider Environmental Services,Inc.

Last office space south from restaurant. 4.8 Earlysville Auto Center Earlysville Auto Center recently opened for business in the former Whyte's Supermarket abutting the Site on the west. The auto center shares the septic system with the Earlysville Green Site. The auto center has a separate water well located on the west side of the auto center building (see Figure 35 above). Runoff from the entire Site and the auto center property enters a stormwater retention basin or"dry pond" (pictured in Figures 29 and 31 above). The auto center should not have any wastewater, floor wash water, spent solvents, or other potential contaminants enter the septic system. However,there is no way for JAS to confirm this in the short time allowed for completing this ESA. The stormwater retention basin undoubtedly will receive runoff from the gravel storage yard and from the paved parking lots on the Site that will contain oil and grease and any other potential contaminants that are spilled on the ground. Fortunately, the predominant potential contaminants that would be anticipated to be flushed into the stormwater basin are readily biodegraded by the natural bacteria present in the stormwater basin. The stormwater basin is not up gradient of the water well located in the far northeast corner of the Site. The groundwater flow direction would carry any contamination that got into the groundwater away from the Site toward the northwest, under the neighboring residential development. Jeffrey A. Sitler Environmental Services,Inc. Page 44 • 4.9 Earlysville Auto,Inc. Across Earlysville Road to the south is Earlysville Auto, Inc. (shown in Figure 37). Earlysville Auto has been in business for more than 35 years and conducts full service auto maintenance and repair. Earlysville Auto is up gradient of the paved parking lot on the west side of the Site. Therefore, any potential contamination from this business should not pose a risk to the drinking water source for the Site. 5.0 CONCLUSIONS AND RECOMMENDATIONS This Phase I Environmental Site.Assessment for the subject Site has been completed in conformance with the scope,and limitations of ASTM Practice E1527-05. Any exceptions to, or deletions from, this practice.are described in Section 6.0 of this report. JAS believes that it has conducted all appropriate inquiry into the current and historical uses and ownership of the subject property, consistent with good commercial and customary practice, in an effort to identify evidence of any existing, suspect, or potential environmental conditions that may impose an environmental liability to, or restrict the use of,the subject Site. • After conducting a visual site inspection and review of historical information, the assessment has revealed a Historic Recognized Environmental Condition in connection with the former Kelly's Korner gasoline release that abutted the Site. • While the DEQ closed the Kelly's Korner case in 2001, a potential MTBE plume existed that could have migrated onto the Site. Since the DEQ did not fully determine the extent of the MTBE plume, it was recommended that a new well water sample be collected to ensure that the well water remains clean after the 12 years since the DEQ closed the case. If the well water is free of detectable contamination, then it will be concluded that the release from the former Kelly's Korner has not impacted the well water quality. Considering the time elapsed since the release and case closure, if the onsite well water has remained free of contamination, then it is not considered a recognized environmental condition. We will await results of the lab analysis of the well water sample collected on July 10,2013. Jeffrey A. Sitter Environmental Services,Inc. Page 45 6.0 LIMITATIONS AND EXCEPTIONS This Phase I ESA has been completed with the assumption that the Client's objective is to develop environmental information about the Site as part of"all appropriate inquiry"under the innocent purchaser defense. This Phase I ESA has not been designed to address potential risks which can have a material environmental or environmentally-driven impact on the business associated with the current or planned use of the Site. The Phase I ESA has been completed for the Site only as it existed on the date of the visual Site investigation. No lists of previous tenants were provided to JAS. The professional opinions and judgments provided in this report are based upon the information gathered on the date of the site inspection and other data reasonably ascertainable, our experience in the area with similar projects, and in accordance with generally accepted professional environmental practice under similar circumstances. Conditions observed and described on the Site are representative of conditions at the specified locations and on the specific date on which they were observed. The passage of time may result in changing conditions at the Site or neighboring properties. Should additional information become available which would affect the status of this report,we reserve the right to amend our opinions and professional judgments. During the preparation of this report,JAS relied upon documents and information provided by others. JAS assumes no responsibility or liability for inaccurate or incomplete data or regulatory information. This assessment does not address naturally occurring hazardous substances, such as elevated heavy metal concentrations in plants and soil, or naturally occurring radon or asbestos in soil or rock. Surface and/or subsurface sampling and analysis of soil, surface water, groundwater, or other materials were also beyond the scope of this assessment. JAS is not qualified to evaluate the relationship of the purchase price to the fair market value of the subject property as required by 40 CFR § 312.19. 7.0 QUALIFICATIONS OF ENVIRONMENTAL PROFESSIONALS Jeffrey A. Sitler, Virginia Certified Professional Geologist and President of JAS,has a masters degree in geology and more than 20 years of experience in environmental site assessments, hazardous waste investigations,petroleum UST site studies, and site remediation.
