1.0 INTRODUCTION

The purpose of this Phase I Environmental Site Assessment is to identify, to the extent feasible, recognized environmental conditions associated with the subject property. A Phase I Environmental Site Assessment has four components: Records Review, Site Reconnaissance, Interviews, and a Report. These specific activities are further defined by the American Society for Testing and Materials (ASTM 1527-13, Standard Practice for Environmental Site Assessments; Phase I Environmental Site Assessment Process, December, 2013). The U.S. Environmental Protection Agency issued a final rule governing “All Appropriate Inquiries” (AAI) under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) on November 1, 2006 (40 C.F.R. Part 312). The EPA has determined that a Phase I Environmental Site Assessment prepared in accordance with ASTM 1527-13 meets the AAI requirements. The following document was prepared at the request of Mr. Terry Ten Eyck of Carlson and Associates on behalf of Ms. Dolores Loveland, the current owner of the property. Ms. Loveland indicated that this report was in response to the potential sale of the property. On January 14th, 2016, Western Environment sent Mr. Ten Eyck an Owner’s Environmental Questionnaire to provide to Ms. Loveland. These questionnaires request copies of past environmental assessment reports and ask for any information regarding environmental issues, liens, covenants, or hazardous material spills associated with the sites. On January 14th, 2016, Ms. Loveland returned the questionnaire (attached) indicating that she had owned the property for 29 years and that she had no knowledge of environmental issues with the property.

2.0 SITE DESCRIPTION This Phase I Environmental Site Assessment was conducted for 2743 Bryant Street, Denver, Colorado, (Figure 1). According to the Denver County Assessors Office records, the property consist of a 0.128 acre vacant lot zoned for general urban use. The site is located in a mixed single family residential and light commercial property area approximately 225 feet south of the intersection of Bryant Street and Speer Boulevard (Figure 2). Surrounding properties consist of an office building to the south, single family residences to the north and west, and an apartment complex to the east. The South Platte River is located 2,600 feet to the southeast of the property. The site occurs at an elevation of approximately 5,300 feet above sea level (USGS Arvada 7.5 Minute Quadrangle, 1980 revised). The topography is generally flat, sloping to the southeast (0 to 3%) toward the South Platte River. The geology in the area consists Pinedale & Bull Lake Age gravels and alluviums overlying the Tertiary and Cretaceous Age Denver/Arapahoe Formation (Tweto, 1979) . Soils are Nunn-Urban land complex and Denver-Ketch-Urban land complex (USRCS). Western Environment reviewed the files of the Colorado Division of Water Resources regarding registered water wells near the 2743 Bryant Street property. The lithologic log from a monitoring well completed at Speer Boulevard and 28th Street indicated that fine sand occurs from the surface to approximately 15 feet. Monitoring reports (attached) from nearby monitoring wells indicate that groundwater is encountered between 7 and 9 feet, with flow to the southeast.

3.0 RECORDS REVIEW The purpose of the records review is to obtain and review information that will help identify the potential for recognized environmental conditions in connection with the property. Availability of records varies from information source to information source, including governmental jurisdictions. Western Environment did not identify, obtain, or review every possible record that might exist with respect to the property. Instead, record information from reasonably ascertainable standard sources was reviewed. The approximate minimum search distance incorporated in the review, the resources utilized, and the number of sites found are listed below:

3.1 Results The record search identified one National Priority List (NPL) site, known as The Denver Radium Superfund Sites, within the ASTM search radius. The Denver Radium sites include 65 different locations in the Denver area. The closest of these areas is located approximately 2,800 feet east of the subject site. Denver was the site of radium processing activities from the early 1900s to the 1920s. After processing activities were abandoned, the locations of the radium facilities and disposal sites were forgotten. The EPA discovered records of the sites in 1979 and they were added to the National Priority List (NPL) of Superfund sites in 1983. The radium processing activities contributed to contamination of soils with radium, thorium and uranium. Tailings from these activities were used for asphalt paving in streets and also as a fill material. The radioactive decay of these elements produces radon gas and radon daughters. All the Denver Radium sites have been remediated by removing the contaminated soils and debris and transporting them to a disposal facility in western Utah. One RCRA Corrective Action site occurs within 1.0 mile of the subject property. Highlands Zuni Plaza, located at 3009 Zuni Street is 1,500 feet northeast of the subject site. The facility is a drycleaner that previously used tetrachloroethlyne. A notice of contamination was issued on May 12th, 2008. Following cleanup activities, the corrective action was terminated on May 23rd, 2008. One landfill site occurs within 0.5 miles of the subject property. The suspected landfill site is located at Riverside Baptist Church, 1,754 feet to the southeast of the subject site at 2401 Alcott Street. Construction debris, with no domestic refuse, liquid, hazardous, or industrial waste, were disposed at the site The underground storage tank sites with activity and proximity to the subject property are discussed below. A UST listed as registered is currently operating within State guidelines. A LUST listed as inactive has had a release, and has been remediated to meet State guidelines. A LUST listed as active has had a release, and remedial activities are on-going. Fourteen Leaking Underground Storage Tank (LUST) sites were identified within the ASTM search radius. Twelve of these sites are listed as inactive, have had a release, and been remediated to meet State and Federal guidelines receiving a No Further Action (NFA) notice. Two of these facilities remain active, with remedial activities on-going. Western Environment

Western environment and ecology, inc. Phase I Environmental Site Assessment: 2743 Bryant Street, Denver, Colorado, 80211 Page -7- personnel reviewed files maintained by the Colorado Department of Labor and Employment, Oil and Public Safety Division (OPS) pertaining to th active LUST sites. The Speer and Zuni Conoco site is located 920 feet east of the site property at 2727 Zuni Street. The site reported a release on February 20th, 2008 during a Phase II Environmental Site Assessment. Remediation activities include air sparge, vapor extraction, and activated carbon injections. Review of the most recent Monitoring and Remediation Report (MRR), dated August 6th, 2015 (attached), indicated that groundwater flow is to the southeast. Based on the groundwater direction, this release does not impact the 2743 Bryant Street property. The 7-Eleven #16147 facility, located at 2609 Federal Boulevard, is 1,270 feet southwest of the subject site. The site has reported two releases. The first release, reported on May 24th, 2002, received a No Further Action notice on December 9th, 2002. Another release was reported on April 29th, 2010, as a result of damaged spill containment buckets at the fill-ports on the UST’s. Remediation on the site includes enhanced fluid recovery and activated carbon injections. Review of the most recent Monitoring and Remediation Report (MRR), dated September 17th, 2015 (attached), indicated that groundwater flow is to the southeast. Based on the distance of the facility and the groundwater direction, this release does not impact the 2743 Bryant Street property. A complete listing of all environmental sites is presented in the appendix.

3.2 Aerial Photography Review Western Environment reviewed aerial photos of the subject site from the earliest available to 2005. The first photo reviewed was from June 12th, 1948 and showed a single family residence on the property and a vacant lot to the south. At this time the site was surrounded by single family residences. North Speer Boulevard and North High School were located north of the property. Photos from May 11th, 1955, showed the Valley Highway (Interstate Highway 25) constructed to the southeast. In photos from April 29th, 1965, and April 25th, 1970, no significant changes to the site were observed. The April 27th, 1974 photograph showed that the house on the property had been removed and the site graded. An office building was constructed on the vacant lot directly south of the project. The residences to the east across Bryant Street were replaced with asphalt parking. In the

Western environment and ecology, inc. Phase I Environmental Site Assessment: 2743 Bryant Street, Denver, Colorado, 80211 Page -8-

May 27th, 1985 photos community parking was constructed along the alleyway west of the vacant site. No significant changes to the site were observed in the photos from September 24th, 1991. Google Earth Images were reviewed for the years following 1991. No significant changes to the subject property were observed on images from June 29th, 1993 to February 29th, 2008. Images from October 7th, 2012 showed the lots east across Bryant Street were cleared of buildings and graded. The most recent image from October 9th, 2015 showed two large apartment buildings constructed to the east. At this time the majority subject site was vacant with community parking occurring on the westernmost portion of the property. A complete listing of the private photos review for this assessment is present in the appendix.

3.3 Governmental Inquiries Western Environment personnel submitted an Environmental Inquiry Request to the Denver Fire Department and to the Denver Health Department on January 14th, 2016. Mr. Michael Erhlich, of the Denver Health Department and Ms. Gina Reichert, of the Denver Fire Department responded to the inquies on January 14, 2016 indicating that there were no records of hazardous waste activities associated with the site.

3.4 City Directories/ Sanborn Map Review Western Environment reviewed Polk City Directories to document the previous uses of the properties surrounding the subject site. The building listed at 2727 Bryant Street, built in 1974, was used as office space for several companies. A list of these businesses is presented in the appendix. The other properties surrounding the site were listed as residential.

4.0 SITE INSPECTION The purpose of a site inspection is to obtain information indicating the likelihood of identifying recognized environmental conditions in connection with the property. On a visit to the site on January 19th, 2016, Western Environment personnel visually and physically observed the property to the extent not obstructed by bodies of water, vegetation, adjacent buildings or other obstacles and debris. At the time of the site inspection, the subject property was vacant, divided into a maintained landscape area on the eastern portion and a parking area on the western portion. The parking area was comprised of a ground level asphalt lot and an overhanging concrete lot with concrete supports extending from the alleyway to the west. The properties adjacent to the site included a multistory office building to the south, single family residences to the north and west, and a multifamily apartment building to the east. Underground natural gas and water lines bordered the site to the east, while overhead power lines were present along the eastern border. Pad mounted transformers were observed on properties adjacent to the south and northeast.

The Superfund Program, administered under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) is an EPA Program to locate, investigate, and clean up the worst hazardous waste sites throughout the United States. The NPL (National Priorities List) is the list of national priorities among the known releases or threatened releases of hazardous substances, pollutants, or contaminants throughout the United States and its territories. The NPL is intended primarily to guide the EPA in determining which sites warrant further investigation. The boundaries of an NPL site are not tied to the boundaries of the property on which a facility is located. The release may be contained with a single property's boundaries or may extend across property boundaries onto other properties. The boundaries can, and often do change as further information on the extent and degree of contamination is obtained. National Priorities List (NPL)

Of these properties, 31 are located in the metropolitan Denver area and include vacant land, industrial operations, buildings, and public streets. Other disposition of this radioactive residue is still unknown. All locations have varying levels of radioactivity. In June 1981, using funds available under the Resource Conservation and Recovery Act, EPA awarded a $100,000 Cooperative Agreement to Colorado, and added $178,600 in September 1981. The funds were to (1) conduct remedial investigations to determine the extent and type of contamination within each of the 31 Denver properties and (2) undertake design activities at 9. Status (July 1983): In August 1982, EPA provided an additional $15,000 in contract support for a feasibility study to identify alternatives for remedial action at the properties. EPA plans to spend about $250,000 to extend the remedial investigation outside the boundaries of six properties and to complete a feasibility study consistent with CERCLA guidelines. Studies of five properties have been completed; the remaining 26 are scheduled for completion by the third quarter of 1984. CERCLIS List

This database returned 1 results for your area.

The United States Environmental Protection Agency (EPA) investigates known or suspected uncontrolled or abandoned hazardous substance facilities under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). EPA maintains a comprehensive list of these facilities in a database known as the Comprehensive Environmental Response, Compensation and Liability Information System (CERCLIS). These sites have either been investigated or are currently under investigation by the EPA for release or threatened release of hazardous substances. Once a site is placed in CERCLIS, it may be subjected to several levels of review and evaluation and ultimately placed on the National Priority List (NPL).

CERCLIS sites designated as "No Further Remedial Action Planned" (NFRAP) have been removed from CERCLIS. NFRAP sites may be sites where, following an intitial investigation, no contamination was found, contamination was removed quickly without the need for the site to be placed on the NPL, or the contamination was not serious enough to require Federal Superfund Action or NPL consideration.

As of February 1995, CERCLIS sites designated "No Further Remedial Action Planned" NFRAP have been removed from CERCLIS. NFRAP sites may be sites where, following an initial investigation, no contamination was found, contamination was removed quickly without the site being placed on the NPL, or the contamination was not serious enough to require Federal Superfund action or NPL consideration. EPA has removed these NFRAP sites from CERCLIS to lift unintended barriers to the redevelopment of these properties. This policy change is part of EPA"s Brownfields Redevelopment Program to help cities, states, private investors and affected citizens promote economic redevelopment of unproductive urban sites.

The NPDES module of the Compliance Information System (ICIS) tracks surface water permits issued under the Clean Water Act. Under NPDES, all facilities that discharge pollutants from any point source into waters of the United States are required to obtain a permit. The permit will likely contain limits on what can be discharged, impose monitoring and reporting requirements, and include other provisions to ensure that the discharge does not adversely affect water quality.

This data is provided by the Colorado Department of Public Health and Environment created from the US Environmental Protection Agency National Priorities List (NPL). The purpose was to improve the location of superfund sites from point data to a polygon.

These large sites are also known as National Priority List (NPL) sites. These sites are being remediated jointly by the State of Colorado and the U.S. EPA under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), This law created Federal authority to respond directly to releases or threatened releases of hazardous substances that may endanger public health or the environment. These sites are undergoing or have completed long- term remedial response actions, that permanently and significantly reduce the dangers associated with releases or threats of releases of hazardous substances that are serious, but not immediately life threatening. Some of the sites have also undergone short-term removals, where actions may be taken to address releases or threatened releases requiring prompt response. CO Superfund - National Priorities List

This database returned no results for your area.

There were nine uranium mill tailings sites in Colorado designated for cleanup under the federal Uranium Mill Tailings Radiation Control Act. These nine sites, know commonly as UMTRA sites, were remediated jointly by the State of Colorado and the U.S. Department of Energy during the late 1980's and early 1990's. Mill tailings were removed from 8 of the mill sites and relocated in engineered disposal cells. A disposal cell is designed to encapsulate the material, reduce radon emanation, and prevent the movement of water through the material. At one site, Maybell, CO, the tailings were stabilized in-place at the mill site. After remediation of the tailings was completed, the State and DOE began to investigate the residual impacts to groundwater at the mill sites. The groundwater phase of the UMTRA program is on-going. CO Solid Waste Sites

This database returned no results for your area.

The Colorado Solid Waste Act requires that solid waste be disposed of in designated facilities. Disposal facilities receive their designation from the local government after the Colorado Department of Public Health and Environment makes a recommendation that the proposed facility can meet the required rules. The solid waste sites depicted in this dataset include landfills, surface impoundments, scrap tire disposal sites, incinerators, landfarming, and specified composting facilities. This dataset does not depict all historic landfills in Colorado. Transfer stations are not required to obtain a designation but are cited in this dataset where the information is available.

RE: SECOND QUARTER 2015 MONITORING AND REMEDIATION REPORT 7-ELEVEN STORE NO. 16147 2609 FEDERAL BOULEVARD, DENVER, COLORADO STANTEC PROJECT NO. 212202495 EVENT ID 11139

Dear Ms. Strauss:

Stantec Consulting Services Inc. (Stantec), on behalf of 7-Eleven, Inc. (7-Eleven), is pleased to submit this Second Quarter 2015 Monitoring and Remediation Report (MRR) for the above referenced site.

Note: The following report was completed using the formatted combined report spreadsheet developed by the State of Colorado Department of Labor and Employment, Division of Oil and Public Safety (OPS). It is a requirement that monitoring reports be completed by using the combined report spreadsheet. The combined report spreadsheet contains locked macros and formatting which may cause numerical data entries to be modified or rounded. Therefore, numerical values shown on the combined report spreadsheet may differ from those shown on original data sources such as from laboratory reports and field notes.

BACKGROUND

Groundwater monitoring and sampling is ongoing following a release associated with damaged spill containment buckets at the fill-ports on the three underground storage tanks (USTs) discovered on April 26, 2010. A suspected release was reported to the Colorado Department of Labor and Employment, Division of Oil and Public Safety (OPS) on April 26, 2010, due to elevated photoionization detector (PID) readings measured in soil samples collected under the spill buckets. On April 29, 2010, the release was confirmed based on soil sample analytical results greater than the risk based screening levels (RBSLs) from samples collected under the regular and midgrade unleaded spill buckets. Three cubic yards of soil were excavated and transported off site for disposal at a landfill.

On April 30, 2010, Stantec received a letter from the OPS requesting a Site Summary Form (SSF) for the above site. On May 24, 2010, a Stantec geologist supervised the installation of monitoring wells MW-1 through MW-4. Stantec submitted the SSF to the OPS on June 23, 2010.

On June 28, 2010, Stantec received a letter from the OPS requesting a Site Characterization Report (SCR). On July 26, 2010, a Stantec geologist supervised the installation of monitoring wells MW-5 through MW-7, and monitoring wells MW-8 and MW-9 on September 7, 2010. Stantec submitted the SCR to the OPS on October 20, 2010, and proposed a Methyl Tertiary Butyl Ether (MTBE) priority classification III for the site. September 17, 2015 Jennifer Strauss Page 2 of 3

On November 10, 2010, Stantec received a letter from the OPS requesting a Corrective Action Plan (CAP). On December 2, 2010, a Stantec geologist supervised the installation of monitoring wells MW-10 and MW- 11.

Stantec submitted a CAP for the site to the OPS on January 7, 2011. The CAP was approved by the OPS on March 9, 2011, for two years of groundwater monitoring and sampling. Sampling for MTBE was approved through the Third Quarter 2011.

The MTBE pathway was eliminated with the Third Quarter 2011 monitoring and sampling data as referenced in the CAP approval letter dated March 9, 2011. Stantec submitted a Scope of Work to the OPS on February 8, 2012, for six, monthly Enhanced Fluid Recovery (EFR) events on MW-7 and MW-10 and continued groundwater and monitoring at the site through the First Quarter of 2014. The purpose of the EFR events would be to perform active remediation at impacted wells, limit further migration of the hydrocarbon plume, and to test the ability of EFRs to perform vapor recovery through the subsurface. Included in the Scope of Work was a Site Specific Target Level (SSTL) Model for benzene in groundwater at the site. The Scope of Work was approved by the OPS in a letter dated July 11, 2012.

EFR events were conducted at the site on August 13, September 17, October 15, November 12, and December 10, 2012, and on January 14, 2013.

A CAP Modification including costs associated with a site-specific BOS-200® injection event and two additional years of monitoring and sampling was prepared by Stantec and submitted to the OPS on May 20, 2014. The CAP Modification was approved by the OPS in a letter dated May 27, 2014.

Between July 16 and 18, 2014, Stantec performed oversight of a BOS-200® injection event at the site. A total of approximately 1,275 pounds of BOS-200® was injected at 13 locations throughout the east-central and southeast portion of the property. In total, approximately 2,600 gallons of BOS-200®, proportioned bacteria concentrate, and water were injected during this event.

GROUNDWATER MONITORING

The Second Quarter 2015 groundwater monitoring and sampling event was conducted on June 29, 2015. On June 29, 2015, the groundwater flow direction was to the southeast with a hydraulic gradient of 0.0360 feet per foot as measured between monitoring wells MW-7 and MW-10.

Groundwater samples were analyzed for benzene, toluene, ethylbenzene, and total xylenes (BTEX), and total petroleum hydrocarbons (TPH) as gasoline range organics (GRO) by EPA method 8260. Maximum Contaminant Levels (MCLs) for the following analytes were exceeded in groundwater samples collected from the listed monitoring wells:

 Benzene: MW-7, MW-10  Toluene: None  Ethylbenzene: None  Total Xylenes: None

CLOSING REMARKS

The next groundwater monitoring event is scheduled for September 2015. Should you have any questions and/or comments, please do not hesitate to contact Adam Lee in our Denver, Colorado office at (303) 285- 4559.

Ms. Jennifer Strauss Colorado Department of Labor and Employment (CDLE) Division of Oil and Public Safety (OPS) 633 17th Street; Suite 500 Denver, Colorado 80202-3660

RE: Monitoring and Remediation Report (MRR) and MTBE Pathway Elimination Request Speer and Zuni Conoco #9454 2727 Zuni Street; Denver, Colorado 80211 EID #10587

Ms. Strauss,

Palmetto Environmental Group, LLC (Palmetto), on behalf of Mr. Minh D. Tran, is submitting this MRR and MTBE Pathway Elimination Request for the above referenced site.

Background:

During a Phase II Environmental Site Assessment (ESA) performed at the site on February 2, 2008, Environmental Property Investigations, Inc. (EPI) drilled three soil borings in what was believed to be a former tank pit on-site. EPI personnel observed hydrocarbon staining in two of the three borings and soil analytical results, obtained on February 6, 2008, confirmed levels of benzene and total volatile petroleum hydrocarbons (TVPH) exceeded Colorado Risk Based Screening Levels (RBSLs). When drilled, none of the three soil borings showed any indication of groundwater development; therefore, groundwater samples were not collected. Although a release was confirmed on February 6, 2008, the owner of the property did not receive a copy of the Phase II ESA Report until February 20, 2008.

The property owner retained Palmetto to complete an investigation of the site and a confirmed release was reported to the CDLE, OPS on February 20, 2008. Palmetto installed six monitoring wells on-site on April 10, 2008 and submitted soil and groundwater samples to Pace Analytical Services, Inc. (Pace) in Lenexa, Kansas for benzene, toluene, ethylbenzene and xylenes (BTEX) analysis by EPA Method 8260. Analytical results indicate soils were below RBSLs; however, groundwater analytical results for samples collected from monitoring wells ZMW-2 and ZMW-3 exceeded RBSLs for benzene, xylenes and methyl-tert-butyl ether (MTBE).

An air sparge / soil vapor extraction (AS/SVE) pilot test was conducted on March 4, 2010. During the 5-hour pilot test, an average vacuum pressure of 124.8 inches of H2O and average recovery velocity of 3.7 cubic feet per minute (CFM) resulted in the recovery of 0.02 pounds (lbs) of vapor.

BOS 200 injections have been conducted at the site on August 2010 and August 2011. During the aforementioned BOS injections, a total of 110 ft3 of BOS 200 (the primary oxidant), 26 ft3 of gypsum (the secondary oxidant) and 7 ft3 of bacteria (catalyst) were injected around the dispenser islands and underground storage tank (UST) basin; and subsequently, groundwater monitoring wells ZMW-03, ZMW-09 and ZMW-10.

Historically, groundwater flows to the east-southeast. Petroleum hydrocarbon contamination originated around the UST basin and dispenser islands but BOS 200 injections effectively contained the contamination on-site.

On December 12, 2012, Palmetto ran a Fate and Transport model using BP Risc. Input parameters for the Fate and Transport model from ZMW-07 to ZMW-03 are provided in the table below.

Parameters Values Hydraulic Conductivity (meters per day) 0.0501 Porosity (%) 25% Hydraulic Gradient (m/m) 0.0534 Fraction Organic Carbon (g oc/g soil) 0.005 Soil Bulk Density (g/cm3) 1.7 Distance Downgradient (meters) 32 Degradation Rate (1/day) 0.0016

Palmetto utilized a benzene concentration in monitoring well ZMW-07 of 0.41 milligrams per liter (mg/L). The degradation rate was calculated using the MNA calculation of clean up time, clean up levels and mile stones concentration versus time. A 100-year simulation was performed and determined that the highest concentration of benzene occurred in year 85 at 0.00107 mg/L. This simulation was confirmed by concentrations observed in ZMW- 03, which had remained below Risk Based Screening Levels (RBSLs) for the past four quarters. Attached with this report are the MNA calculations and the Fate and Transport model.

On January 18, 2013, Palmetto received a denial of closure for the site. The denial letter requested continued monitoring of the benzene plume until concentrations stabilize or decrease at monitoring well ZMW-09, continued monitoring of the MTBE plume until concentrations stabilize or decrease at monitoring well ZMW-03, collection of soil samples from the vicinity of monitoring well ZMW-07 and ZMW-09 analyzed for Polycyclic Aromatic Hydrocarbons (PAH) to demonstrate completion of the soil-to-groundwater leachate pathway, identification of possible Points of Exposure (POE) and investigation of utility corridors for possible impacts and migration of contamination.

On May 7, 2013, Palmetto collected two confirmatory soil samples adjacent to ZMW-07 at nine to eleven feet below ground surface (ft/bgs) and adjacent to ZMW-09 at seven to eight ft/bgs. All soil samples were collected using laboratory supplied containers, placed in a rigid plastic cooler with ice and sent via Fed Ex Overnight Services to Pace in Lenexa, Kansa, under appropriate COC documentation. Additionally, one soil sample was sent to Pace in St. Rosa, Louisiana, under appropriate chain of custody (COC) documentation to be analyzed for Fraction Organic Carbon (FOC) by analytical method ASTM D2974, for Fate and Transport Modeling.

Soil samples were analyzed for BTEX, TVPH and the 16 priority PAHs. No soil samples exceeded RBSLs for the analyzed constituents. Additionally, a soil sample was collected from the utility corridor near the southern property boundary; based on field screening, the sample was considered clean and laboratory analysis was deemed unnecessary. Soil sample locations and results are attached in the Soil Sample Figure tab and soil boring logs are attached in the Borehole and Well Logs tab of this MRR.

On June 14, 2013, Palmetto ran a Fate and Transport model using BP Risc. Input parameters for the Fate and Transport model from monitoring well ZMW-07 to ZMW-03 are provided in the table below.

Palmetto utilized a benzene concentration of 0.24 mg/L (highest concentration in past four quarters at ZMW-07) and a hydraulic gradient of 0.0576 from the second quarter 2013 MRR. A 100-year simulation was performed and determined that the highest benzene concentration occurred in year 85 at 0.000788 mg/L. Palmetto ran another Fate and Transport model changing the distance downgradient to 11 meters (ZMW-09 to ZMW-03) and source concentration to 0.024 mg/L (highest concentration in past four quarters at ZMW-09). A 100-year simulation was performed and determined the highest benzene concentration occurred in year 100 at 0.0012 mg/L. MNA calculations and the Fate and Transport models are attached in the Model Input & Results tab of this MRR.

During the second quarter of 2015, a review of MTBE concentrations indicated a decreasing trend in ZMW-03 and a stable trend in ZMW-07. This information is supported by the attached concentration vs. time model. Additionally, groundwater concentrations in ZMW-08 have never shown MTBE being above the taste and odor threshold. Based on this observation, Palmetto calculated the SSTL for MTBE utilizing the BP RISC modeling software. The following input parameters were utilized for the SSTL model and are provided in the table below.

Parameters Values Hydraulic Conductivity (meters per day) 0.0501 Porosity (%) 25% Hydraulic Gradient (m/m) 0.0569 Fraction Organic Carbon (g oc/g soil) 0.014 Soil Bulk Density (g/cm3) 1.7 Distance Downgradient (meters) ZMW-03 to ZMW-08 50 Degradation Rate (1/day) 0

Palmetto utilized a MTBE concentration of 0.18 mg/L in groundwater monitoring well ZMW-03 and observed that MTBE remains below the RBSL in groundwater monitoring well ZMW-08. Downgradient definition of MTBE has been achieved for 7 years; therefore it does not appear continued sampling of MTBE is warranted. Based on the above modeling data MTBE does not present a threat to human health or the environment.

Current Activities:

On July 16, 2015, Palmetto sampled six groundwater monitoring wells and submitted the groundwater samples for analysis of BTEX, TVPH and MTBE by EPA Method 8260. Groundwater samples were collected using laboratory supplied containers, placed in a rigid plastic cooler with ice and sent via Federal Express (Fed Ex) Overnight Services to Pace in Lenexa, Kansas, under appropriate chain of custody (COC) documentation.

Listed below are the observations from the July 16, 2015 sampling event:

• Based on groundwater contouring, the groundwater flow direction is to the southeast, which is consistent with previous sampling events. MRR Cover August 2015 Page 4 of 4

• A hydraulic gradient of 0.0546 ft/ft was measured between monitoring wells ZMW-10 and ZMW-08. • Analytical results indicate groundwater monitoring wells ZMW-02, ZMW-07 and ZMW-09 exceeded the RBSL for benzene, with ZMW-09 having the highest concentration at 0.15 mg/L. • Analytical results indicate none of the groundwater monitoring wells that were sampled exceeded the taste and odor threshold for MTBE. • The groundwater elevation in ZMW-04 was gauged and not sampled, in accordance with the sampling plan.

During the last week of July 2015, BOS 200 injections were conducted at the site. The injections were conducted along the southern property boundary from approximately the location of ZMW-07 east to ZMW-03. The BOS 200 Injection Summary Report and Injection Location Figure have not yet been completed and will be included in the fourth quarter 2015 MRR.

Future Recommendations:

The request to eliminate MTBE from the sampling plan that was submitted by Palmetto during the second quarter of 2015 was denied by the OPS. The model data from the second quarter of 2015 supporting the MTBE elimination request is provided above. Palmetto sampled the wells for MTBE during this sampling event and analytical results indicated that none of the wells exceeded the taste and odor threshold for MTBE. Because MTBE concentrations in groundwater continue to show a decreasing trend, Palmetto recommends eliminating MTBE from the sampling plan.

Palmetto will continue to conduct monitoring events at this site.

Statement of Qualifications

“We declare that, to the best of our professional knowledge and belief, we meet the definition of Environmental professional as defined in 40 CFR 312 and 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 developed and performed the appropriate inquiries in conformance with the standards and practices set forth in 40 CFR Part 312.”

Western environment and ecology, inc. REAL ESTATE TRANSFER ENVIRONMENTAL AUDITS (RETA) In response to provisions contained within the Comprehensive Environmental Response Compensation and Liability Act (CERCLA) and the Resource Conservation and Recovery Act (RCRA), lending institutions, firms and individuals involved with property transfers have become painfully aware of the costs associated with environmental liabilities. In an attempt to make informed decisions and potentially avail themselves of the "innocent purchaser defense" as defined in CERCLA, lending institutions are requiring the completion of an environmental audit. Previously, the completeness and the thoroughness of these audits varied as greatly as the cost. However, in late 1992, the American Society of Testing and Materials (ASTM) adopted specific standards for completion of Phase I audits. The ASTM standards (E-1527 and E-1528) are quite specific as to the level of investigation necessary to complete the audit. Western Environment and Ecology, INC. has performed Real Estate Transfer Environmental Audits to ASTM standards long before the standards were adopted. Additionally, Western Environment and Ecology, Inc. personnel have provided training to FDIC regional offices on environmental compliance and financial institution liabilities. This familiarity with lending institutions and more than fifteen years of experience in performing RETA's allows Western Environment and Ecology, Inc. to provide efficient and complete reports meeting short time frame requirements.
