SUMMARY

This Phase I ESA was performed in accordance with our proposal dated December 15, 2010, and was conducted consistent with the procedures included in ASTM E 1527-05, Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process. The ESA was conducted under the supervision or responsible charge of Timothy L. Bennett, R.G., environmental professional. Adam J White performed the site reconnaissance on January 21, 2011 and February 23, 2011.

A cursory summary of findings is provided below. It should be recognized that details were not included or fully developed in this section, and the report must be read in its entirety for a comprehensive understanding of the items contained herein.

• The site is located along Discovery Ridge Parkway and Discovery Drive within the University of Missouri, Discovery Ridge Research Park, Columbia, Boone County, Missouri. The site is an approximate 120-acre tract of land, improved with three machine shed structures located on the northern portion, occupied by the University of Missouri-Genetics Farm, and a Quonset hut located on the western portion occupied by the United States Department of Agricultural (USDA). The on-site structures are utilized for the storage of multiple pieces of research equipment. The remainder of the site consists of vacant undeveloped land utilized for row crop production, and livestock pasture with portions developed as graded lots associated with the current-day Discovery Ridge Research Park.

• On-site features observed during the site reconnaissance included interior floor drains within the large machine shed, four tractors, eight pad mounted transformers, three inactive pole-mounted transformer, a septic system, an approximately 500-gallon propane AST, fill dirt, an air compressor and an intermittent stream. On-site RECs were not identified based on visual findings during the site reconnaissance.

• Based on review of the historical information, the site has predominately been vacant farmland consisting of both row crop production and livestock pasture from at least 1934 to 2006. The western portion of the site has been utilized as a research park development from approximately 2006 to present-day. Additionally, the eastern portion of the site has always been utilized as farmland and livestock pasture land.

The northern portion of the site is currently utilized as a University of Missouri plant genetic research farm. A residential structure was located at the Genetics Farm, on the northern portion of the site from approximately 1945 to 2001 at which time the residential structure was demolished. Multiple small machine shed structures have been located at the Genetics Farm, on the northern portion of the site from at least Reliable

• Terracon Project No. 09117701 1956 to the mid 2000s with two small machine structures still present on-site. The large machine shed structure located at the Genetics Farm was placed on-site in approximately 2007. A Quonset hut structure utilized by the USDA has been located on the western portion of the site from approximately 1965 to present-day. A residential structure was located on the western portion of the site, east of the current-day on-site Quonset hut from approximately 1945 to approximately the I1980s. A small log cabin type structure was located on the central portion of the site from approximately 1945 to 1980. Terracon did not identify RECs for the site based on the historical use of the site or adjoining properties.

The current-day adjoining properties of the subject site consist of the following:

• Sugar Grove Road, RI Lake, and livestock pasture land, followed by row crop farmland and livestock pasture land to the north;

• Highway 63, followed by grass and tree covered land with Phillips Lake to the south;

• A trailer park, followed by an elderly care facility to the northwest and Highway 63 to the west; and

• A residential structure, a barn, wooded land and livestock pasture land, followed by pasture land associated with the University of Missouri Beef Farm to the east.

Collective Adjoining - Properties encompassed by the site

• ABC Laboratories encompassed by Lot 5, Lot 17, Lot 18, Lot 2, and Lot 6;

• Radii with pad-mounted transformer encompassed by Lot 2, Lot 8, and Lot 15;

• Stormwater drainage easement encompassed by Lot 2, Lot 7, and Lot 8;

• A City of Columbia, sanitary sewer pump station, with diesel generator encompassed on the southwestern portion of Lot 9.

A City of Columbia sanitary sewer pump station with a diesel generator was observed located on a collective adjoining property on the southwestern portion of Lot 9. The City of Columbia sanitary sewer pump station currently does not represent a REC to the site due to duration of time located on and encompassed by Lot 9.

Indications of RECs were not observed with the current-day adjoining and collective adjoining properties.

• The regulatory review identified one Missouri Department of Natural Resources facility within the specified search distance; however, the facility is not a REC due to regulatory status, and duration of time located within the vicinity of the site.

Additionally an Orphan facility was identified located on the north adjoining property.

Terracon Project No. 09117701 The local agency inquiries for environmental records did not reveal RECs in connection with the site from the agencies that have responded by the issuance of this report.

The following previous environmental report associated with portions of the current-day Discovery Ridge Research Park and its associated collective adjoining properties, was provided by the University of Missouri for review: Phase I Environmental Site Assessment Discovery Ridge, prepared by Terracon, prepared for University of Missouri, Terracon proiect number 09067718, dated May 31, 2006. The 2006 Terracon ESA report did not identify RECs associated with the subject site; however did recommend the cleanout of the oil/water separator in the garage of the USDA Field Research Building (FRB), and if encountered during proposed site activities the proper abandonment of the water well and the closure of the septic tank located within the vicinity of the current-day ABC Laboratories' facility.

The oil/water separator, water well and septic tank discussed within Terracon's 2006 ESA report were identified as located on the site's collective adjoining properties.

• The following previous geotechnical engineering report associated with Discovery Ridge was provided by the University of Missouri for review: Geotechnical Engineering Report Discovery Ridge Lots 2. 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, and 18, prepared by Terracon, prepared for University of Missouri.

Terracon proiect number 09105094, dated February 17, 2011. The 2011 Terracon geotechnical engineering report stated that nine soil borings were advanced at the site. According to the geotechnical report, fill soils were encountered in borings B-3 and B-4 on Lot 2 and Lot 8, respectively. It was noted that the material was placed as part of a mass grading in 2008 and that Terracon was onsite to observe and test the density and moisture during the placement of the engineered fill material. Additionally the report indicated that historically a pond may have been present in the vicinity of Lot 16 and on the northeastern portion of Lot 2.

Typically on-site depth to groundwater was encountered between 12 feet and 18.5 feet below existing grade.

• Pursuant to the client's request, an agency file review was conducted to identify the potential occurrence of cultural resources on the site. The Section 106 Review form, signed by Mark Miles, Deputy State Historic Preservation Officer, dated March 7, 2011 states that "an adequate cultural resource survey of the project area has been previously conducted. It has been determined that for the proposed undertaking there will be no historic properties affected."

Phase I ESAs, such as the one performed at this site, are of limited scope, are noninvasive and cannot eliminate the potential that hazardous, toxic, or petroleum substances are present or have been released at the site beyond what is identified by the limited scope of this ESA. In conducting the limited scope of services described herein, certain sources of information and public records were not reviewed. It should be recognized that environmental concerns may be documented in public records that were not reviewed. No ESA can wholly eliminate uncertainty regarding the potential for RECs in connection with a property. Performance of this practice is intended to reduce, but not eliminate, uncertainty regarding the potential for RECs. No warranties, express or implied, are intended or made.

The limitations herein must be considered when the user of this report formulates opinions as to risks associated with the site or otherwise uses the report for any other purpose.

These risks may be further evaluated - but not eliminated - through additional research or assessment. We will, upon request, advise you of additional research or assessment options that may be available and associated costs.

1.4 Additional .Scope Limitations, ASTM Deviations and Significant Data Gaps Based upon the agreed-on scope of services, this ESA did not include subsurface or other invasive assessments, business environmental risk evaluations, or other services not particularly identified and discussed herein. Reasonable attempts were made to obtain information within the scope and time constraints set forth by the client; however, in some instances, information requested is not, or was not, received by the issuance date of the report. Consideration of such information is beyond the scope of this assessment.

Information obtained for this ESA was received from several sources that we believe to be reliable; nonetheless, the authenticity or reliability of these sources cannot and is not warranted hereunder. This ESA was further limited by the following:

• Credentials of the company (Statement of Qualifications) have not been included in this report but are available upon request.

• Pertinent documents are referred to in the text of this report, and a separate reference section has not been included.

• At the time of the February 23, 2011 site reconnaissance, the two small machine shed type storage structures located on Lot 17 were locked and inaccessible.

The oil/water separator, water well and septic tank discussed within Terracon's 2006 ESA report were identified as located on the site's collective adjoining properties.

A review of readily available historical information revealed that the development of the current-day buildings on the site appeared to have begun between 1939 and 1948. The lake on the site appeared to have been constructed between approximately 1948 and 1959 and the lagoon constructed between 1974 and 1981.

The regulatory review identified no USEPA facilities and one MDNR facility within the vicinity of the site. Also identified in the regulatory database report was an orphan facility identified as the University of Missouri-South Farm. The University of Missouri-South Farms facility was identified as a State Hazardous Waste Site (SHWS). This facility was observed at the time of the site visit to be located approximately 1 mile east of the site. The regulatory review and agency inquires did not reveal RECs associated with the site.

Terracon interviewed Mr. John Poehlmann regarding the site. Mr. Poehlmann is the Assistant Director of the Missouri Agricultural Experiment Station and superintendent of the University of Missouri-South Farms of which the site is located within. Mr. Poehlmann stated that the site currently and historically has been used for agricultural research and teaching which included maize genetics crop research, swine nutrition, beef cattle management and grazing, agricultural equipment development and cropping for grain silage and uptake of nutrients from lagoon application. To Mr. Poehlmann's knowledge, the nine buildings located on the site were constructed between the. 1970's and approximately.2002.

According to Mr. Poehlmann, there are pits for the collection of animal waste beneath a building which formerly housed sheep and swine. The wastes were surface and injection applied as plant nutrients. The on-site lagoon operated under the MDNR permit MO-G01 0024. Mr. Poehlmann stated that a well is located on the site. The exact location of the well was not known. However, the well was installed in the approximate 1950's and reported to be abandoned. Mr. Poehlmann has no knowledge of any aboveground or underground storage tanks for chemicals or petroleum, past use, treatment, disposal or generation of hazardous materials or petroleum products associated with the subject site.

A pad-mounted transformer was located on the southeastern portion of Lot 17. Three inactive pole-mounted transformers were observed on the northern portion of Lot 17.. According to Mr. Bowne, the inactive pole-mounted transformers have been inactive since the demolishing of the residence historically located at the Genetics Farm. Transformers contain mineral oil which may contain minor amounts of PCB and could be considered "PCB contaminated" (PCB content of 50-500 ppm).

The City of Columbia maintains responsibility for the transformers, and if the transformers were "POB contaminated," the utility company is not required to replace the transformer fluids until a release is identified. However, no evidence of current or prior release was observed in the vicinity of the electrical equipment during the site reconnaissance.

Releases or Potential Releases Construction/demolition debris and/or dumped fill dirt Approximately 1-acre of fill dirt was observed located on the northern portion of Lot 9 at the time of the site reconnaissance. Mr. Brent Mahoney with the University of Missouri, South Farms, Field Operations indicated that the fill material located on Lot 9 has been placed on'-

site over the past two years and originated from the future location of the Missouri Conservation facility located south of Gans Road approximately 1.5 miles south of the site.

APPENDIX B Description of Terms and Acronyms

Description of Selected General Terms and Acronyms TermlAcronym Description Asbestos Containing Material. Asbestos is a naturally occurring mineral, three varieties of which (chrysotile, amosite, crocidolite) have been commonly used as fireproofing or as binding agents in construction materials. Inhalation of asbestos fibers has been documented to cause asbestosis (scarring of the lung), lung cancer, and mesothelioma (a cancer of the chest wall lining).

Most Federal and State agencies define ACM as a material containing more that one (1) percent asbestos, although some states, such as California, define ACM as material containing 0.1% or more asbestos. In order to determine the ACM status of suspect building materials, a minimum number of samples must be collected and analyzed, depending on the type and quantity of the suspect material. A suspect material can only be confirmed as non-ACM when analytical results of all required samples are below applicable regulatory limits. Asbestos concentrations are generally determined using polarized light microscopy or transmission electron microscopy. An asbestos containing ACM material may be classified as either friable or non-friable. Friable materials are those that, when dry, can be crumbled, pulverized, or reduced to powder by hand pressure.

Non-friable ACM are materials in which the asbestos fibers are more firmly bound in a matrix of tar, plastic or other such material, and which have a lower potential for asbestos fiber release.

Federal and State regulations require that that an asbestos survey be performed prior to renovation, dismantling, demolition or other activities that may disturb suspect or confirmed ACM unless such materials are removed as ACM prior to planned disturbances. ACM removal may also be required if confirmed ACM becomes damaged, or if renovation or demolition activities could result in damage to confirmed or suspect ACM. Depending upon the quantity, notification to Federal or State regulatory agencies may be required prior to ACM removal (abatement) operations. Abatement of friable or potentially friable ACM must be performed by a licensed abatement contractor in accordance with applicable federal, state, or local regulations. OSHA worker protection regulations will also apply.

AHERA Asbestos Hazard Emergency Response Act Above Ground Storage Tanks. ASTs are generally described as storage tanks less than 10% of which are below ground (i.e., buried). Tanks located in a basement, but not AST buried, are also considered ASTs. Whether, and the extent to which, an AST is regulated, is determined on a case-by-case basis and depends upon tank size, its contents and the jurisdiction of its location.

AULs Activity and Use Limitations BGS Below Ground Surface BTEX Benzene, Toluene, Ethyl benzene, and Xylenes. BTEX are VOC components found in gasoline and commonly used as analytical indicators of a petroleum hydrocarbon release.

Exposure to elevated levels of radon creates a risk of lung cancer; this risk generally increases as the level of radon and the duration of exposure increases. Outdoors, radon is diluted to such low concentrations that it usually does not present a health concern. However, radon can Radonaccumulate in building basements or similar enclosed spaces to levels that can pose a risk to human health. Indoor radon concentrations depend primarily upon the building's construction, design and the concentration of radon in the underlying soil and groundwater.

PHASE I ENVIRONMENTAL SITE ASSESSMENT DISCOVERY RIDGE EAST OF LENOIR STREET AND SOUTH OF SUGAR GROVE LANE COLUMBIA, BOONE COUNTY, MISSOURI Project No. 09067718

• May 31, 2006 EXECUTIVE

SUMMARY

This Phase I Environmental Site Assessment (ESA) of the above-referenced site was performed in accordance with our proposal dated April 6, 2006, and in general accordance with the consensus document known as ASTM E 1527-00, a guide for conducting ESAs.

Tim Bennett performed the site reconnaissance on April 18, 2006.

The site is a 114-acre portion of the University of Missouri-South Farm which is proposed to be developed with a research park. The site is located at the approximate southwestern corner of the South Farm east of Lenoir Street and south of Sugar Grove Lane. Nine buildings associated with agricultural and engineering research and related equipment storage exist on the site. The site is generally located on the southeastern portion of Columbia, Boone County, Missouri.

A cursory summary of findings is provided below. It should be recognized that details were not included or fully developed in this section, and the report must be read in its entirety for a comprehensive understanding of the items contained herein.

• The site is located on an irregular-shaped plot of approximately 1 14 acres of land.

The site consists predominantly of farmland with nine buildings associated with agricultural research located on the northwestern portion of the site and a lake. The site is owned by the University of Missouri. According to Mr. John Poehlmann, Assistant Director of University of Missouri Agricultural Station and superintendent of the site, the site currently and historically has been used for agricultural research and teaching which included maize genetics crop research, swine nutrition, beef cattle management and grazing, agricultural equipment development, and cropping for grain, silage and uptake of nutrients from lagoon application.

• Observations made during Terracon's reconnaissance of the subject site included, but was not limited to 55-gallon drums, 5-gallon containers; an oil/water separator and sump associated with an indoor floor drain; aboveground storage tanks (ASTs) for water; a temporary underground storage tank (UST) for collection of wastewater; electrical transformers; a lake and a lagoon. Observations did not indicate iii

EXECUTIVE

SUMMARY

(cont.) Trao Terracon recognized environmental conditions (RECs) associated with these features at the time of the site reconnaissance.

• Based on a review of historical information including, historical topographic maps, aerial photographs, and interviews, the subject site appears to have been developed by at least 1935 with apparent farmstead buildings. The development of the current-day buildings on the site appears to have begun between 1939 and 1948. The lake on the site appears to have been constructed between approximately 1948 and 1959 and the current-day lagoon constructed between 1974 and 1981. A review of registered water well information provided by the Missouri Department of Natural Resources (MDNR)-Geological Survey and Resource Assessment Division (GSRAD) did not identify a water well which is reportedly on the site at an unknown location. Development of the surrounding areas appears to have begun by at least 1935 with the development of current-day Highway 63 to the west and south and homes and buildings associated with surrounding farmland to the north, south, and west of the subject site. The development of the current-day Ed's Mobile Home Park and Sunset Mobile Home Park northwest of the site began between approximately 1948 and 1959.

• The current-day adjoining properties of the subject site consist of the following:

• Ed's Mobile Home Park and Sunset Mobile Home Park, farmland with University of Missouri storage buildings, and Sugar Grove Lane, to the north,

• Farmland and buildings associated with the University Beef Farm to the east,

• Lenoir Street, a residential house, Highway 63, Ponderosa Drive and farmland to the south, and

• Lenoir Street, Highway 63, Ponderosa Drive and the Phillips Farm to the west.

The adjoining properties do not appear to represent a REC to the subject site at this time.

• The regulatory database review identified no Environmental Protection Agency (EPA) facilities, and one (1) MDNR Underground Storage Tank (UST) facility within the specified search radii. Based on the regulatory status and topographic distance relative to the subject site, this facility does not appear to represent a REC to the subject site.

Recommendations Based on the Scope of Services for this assessment, Terracon did not identify conditions which, in our opinion, require additional investigation at this time. However;

• Terracon recommends a current cleanout of the oil/water separator in the garage of the USDA Field Research Building (FRB).

iv

EXECUTIVE

SUMMARY

(cont.) Terracon Trao

• Water wells may provide a direct migration pathway for contaminants to reach aquifers underlying a site, and therefore become a source of environmental concern. If the well on the site is encountered during the proposed site activities, Terracon recommends that the water well be properly abandoned according to MDNR regulations. Proper abandonment of water wells should be performed by a water well driller licensed with the State of Missouri, and requires notification to MDNR prior to abandonment.

• If the septic tank is to be encountered during future site development activities, it should be closed in accordance with Boone County regulations, if applicable.

1.0 INTRODUCTION

1.1 Site Description Site Description Site Name Discovery Ridge East of Lenoir Street and south of Sugar Grove Lane, Columbia, Boone Site Location/Address CutMsor Land Area Approximately 114 acres Additional Site The subject site consists of predominantly farmland with a lake, lagoon, Improvements and nine buildings located on the northwestern portion of the site.

The site location is depicted on Figure 1 of Appendix A, which was reproduced from a portion of the Columbia, Missouri Quadrangle, United States Geological Survey (USGS) 7.5 minute series topographic map. A Site Diagram of the site and adjoining properties is included as Figure 2 of Appendix A. Acronyms and terms used in this report are described in Appendix E.

1.2 Scope of Work This Environmental Site Assessment (ESA) was performed in accordance with our proposal dated April 6, 2006 and in general accordance with the consensus document known as ASTM E 1527-00, a guide for conducting ESAs. The purpose of this ESA was to assist the client in developing information to identify recognized environmental conditions (RECs) in connection with the site as reflected by the scope of this report. This purpose was undertaken through a regulatory database review, historical and physical records review, interviews, including local government inquiries, as applicable, and a visual noninvasive reconnaissance of the site and adjoining properties. Limitations and ASTM deviations are evident from reviewing the applicable scope of services and the report text.

1.3 Standard of Care This ESA was performed in accordance with generally accepted practices of this profession, undertaken in similar studies at the same time and in the same geographical area. We have 1

Discovery Ridge Terracon Project No. 09067718 May 31, 2006 endeavored to meet this standard of care, but may be limited by conditions encountered during performance, a client-driven scope of work, or inability to review information not received by the report date.

Phase I ESAs, such as the one performed at this site, are of limited scope, are noninvasive and cannot eliminate the potential that hazardous, toxic, or petroleum substances are present or have been released at the site beyond what is identified by the limited scope of this ESA. In conducting the limited scope of services described herein, certain sources of information and public records were not reviewed. It should be recognized that environmental concerns may be documented in public records that were not reviewed. No ESA can wholly eliminate uncertainty regarding the potential for recognized environmental conditions in connection with a property. Performance of this practice is intended to reduce, but not eliminate, uncertainty regarding the potential for recognized environmental conditions.. No warranties, express or implied, are intended or made. The limitations herein must be considered when the user of this report formulates opinions as to risks associated with the site or otherwise uses the report for any other purpose. These risks may be further evaluated - but not eliminated - through additional research or assessment. Terracon will, upon request, advise you of additional research or assessment options that may be available and associated costs.

1.4 Additional Scope Limitations and ASTM Exceptions eased upon the agreed-on scope of services, this ESA did not include subsurface or other invasive assessments, business environmental risk evaluations, or other services not particularly identified and discussed herein. Reasonable attempts were made to obtain information within the scope and time constraints set forth by the client; however, in some instances, information requested is not, or was not, received by the issuance date of the report. Consideration of such information is beyond the scope of this assessment.

Information obtained for this ESA was received from several sources that we believe to be reliable; nonetheless, the authenticity or reliability of these sources cannot and is not warranted hereunder. This ESA was further limited by the following:

• Credentials of the environmental assessors (resumes) and of the company (Statement of Qualifications) have not been included in this report but are available upon request.

This report represents our service to you as of the report date and constitutes our final document; its text may not be altered after final issuance. Findings in this report are based upon the site's current utilization, information derived from the most recent reconnaissance and from other activities described herein; such information is subject to change. Certain

Discovery Ridge Terracon Project No. 09067718 May 31, 2006 indicators of the presence of hazardous substances or petroleum products may have been latent, inaccessible, unobservable, or not present during the most recent reconnaissance and may subsequently become observable (such as after site renovation or development).

Further, these services are not to be construed as legal interpretation or advice.

1.5 Reliance This ESA report is prepared for the exclusive use and reliance of the University of Missouri.

Use or reliance by any other party is prohibited without the written authorization of the University of Missouri and Terracon.

Reliance on the ESA by the client and all authorized parties will be subject to the terms, conditions and limitations stated in the proposal, ESA report, and Terracon's Agreement for Services. The limitation of liability defined in the Agreement for Services is the aggregate limit of Terracon's liability to the client and all relying parties.

The current-day buildings on the northwestern portion of the site appear to have been developed between approximately 1939 and 2005. The adjoining properties appear to have begun development by at least 1939 with current-day Sugar Grove Lane to the north and Highway 63 and apparent farmstead buildings to the west. The trailer park to the northwest appears to have begun development between 1939 and 1959. Visual surface indications do not appear to reveal obvious RECs on the subject site or adjoining properties.

3.3 Historical Fire Insurance Maps Historical fire insurance maps produced by the Sanborn Map Company were requested from Environmental Data Resources, Inc. (EDR) to evaluate past uses and relevant characteristics of the site and adjoining properties.

Based upon inquiries to the above-listed Sanborn provider, Sanborn Maps were not available for the site area in their collection. EDR confirmation of "no coverage" for the subject site is included in Appendix B.

3.4 Ownership Information At the direction of the client, a title search was not included as part of the scope of services.

3.5 Historical Interviews Terracon interviewed Mr. John Poehlmann regarding the subject site. Mr. Poehlmann is the Assistant Director of the Missouri Agricultural Experiment Station and superintendent of the University of Missouri (University) South Farm of which the subject site is located within. Mr.

Poehlmann has been associated with the site between 1983 through 1986 and since January of 2000. To Mr. Poehlmann's knowledge, the site was previously owned by unspecified multiple landowners previous to ownership by the University. Mr. Poehlmann stated that the site currently and historically has been used for agricultural research and teaching which included maize genetics crop research, swine nutrition, beef cattle 9

Discovery Ridge Terracon Project No. 09067718 May 31, 2006 management and grazing, agricultural equipment development, and cropping for grain, silage and uptake of nutrients from lagoon application. To Mr. Poehlmann's knowledge, past tenants of the site have included USDA-ARS and Animal Sciences faculty. Mr.

Poehlmann stated that the current and historic uses of the surrounding property has been for agricultural research in beef, corn genetics, entomology, atmospheric science, and a Missouri Department of Conservation fishing lake.

Mr. Poehlmann stated that there are nine structures on the site that are associated with research and development for civil engineering and agriculture. To Mr. Poehlmann's knowledge, the buildings were constructed between thie 1970's and approximately 2002.

According to Mr. Poehlmann, waste water from all buildings except the civil engineering research building discharge to the on-site lagoon until recently. The civil engineering building waste water is handled by septic system located to the west of the building.

Currently the waste water from the USDA Field Research Building (FRB) is being collected in a 1500-gallon temporary underground storage tank (UST) until the upcoming City of Columbia sewer system is installed. Mr. Poehlmann stated that an oil/water separator is located beneath a floor drain in the FRB and is cleaned out on an as needed basis.

According to Mr. Poehlmann, there are pits for the collection of animal waste beneath buildings which formerly housed sheep and swine. The wastes were surface and injection applied as plant nutrients. The lagoon operates under MDNR permit MO-G010024. Mr.

Poehlmann stated that a well is located on the site. The exact location was not known.

However, the well was installed in the approximate 1950's and reported to be abandoned and have a steel cap welded to the top of the casing. The well was reportedly used to provide potable water for livestock. According to Mr. Poehlmann waste oil from the site is collected by the University Field Operations staff or Safety Kieen. Mr. Poehlmann stated that solvents, paints, oils, fuels, and lubricants typically used for agriculture and research are present on the site. According to Mr. Poehlmann, the site is inspected at least twice annually or more to identify unlabelled containers and unknown substances. Mr.

Poehlmann was aware of hydraulic equipment at the site which included portable testing equipment at the civil engineering building and forklifts used by the USDA. Mr. Poehlmann has no knowledge of any aboveground or underground storage tanks for chemicals or petroleum, past use, treatment, disposal or generation of hazardous materials or petroleum products, polychlorinated biphenyl (PCB) equipment, solid waste disposal, or any pending, threatened, or past litigation, administrative proceedings, violations of environmental laws, or possible litigation relating to hazardous substances or petroleum products associated with the subject site.

4.0 RECORDS REVIEW The United States EPA and State of Missouri database information was provided by EDR, a contract information services company, for indications of environmental concern on and in the vicinity of the site. Information in this section is subject to the accuracy of the data provided by the information services company and the date at which the information is updated, and the scope herein did not include confirmation of facilities listed as "unmappable" by regulatory databases.

In some of the following subsections, the words up-gradient, cross-gradient and down-gradient refer to the topographic gradient in relation to the site. As stated previously, the groundwater flow direction and the depth to shallow groundwater, if present, would likely vary depending upon seasonal variations in rainfall and the depth to the soil/bedrock interface. Without the benefit of on-site groundwater monitoring wells surveyed to a datum, groundwater depth and flow direction beneath the site cannot be ascertained.

4.1 Federal and State Databases Listed below are the names and number of facilities identified on federal and state databases within the indicated search areas. Database definition, descriptions, and the database search report are included in Appendix C.

Database {Description Federal and State Databases Rdu Facilities Federal The National Priorities List (NPL) is the USEPA's database of NPL uncontrolled or abandoned hazardous waste facilities that have been 1.0 0 listed for priority remedial actions under the Superfund Program.

The CERCLIS database is a compilation of facilities which the CERCLIS/ USEPA has investigated or is currently investigating for a release or 0.0 NFRAP threatened release of hazardous substances pursuant to the Comprehensive Environmental Response, Compensation and 11

Discovery Ridge Terracon Project No. 09067718 May 31, 2006 Databaser Description Liability Act (CERCLA) of 1980. NFRAP (No Further Remedial Action Planned) refers to facilities that have been removed and archived from its inventory of CERCLA sites.

The USEPA maintains a database of RCRA facilities associated with RCRA treatment, storage, and disposal (TSD) of hazardous materials that CORRACTS/ are undergoing "corrective action". A "corrective action" order is TSD issued when there has been a release of hazardous waste or constituents into the environment from a RCRA facility.

The RCRA Non-CORRACTS/TSD Database is a compilation by the RCRA Non- USEPA of facilities that report storage, transportation, treatment, or CORRACTSI disposal of hazardous waste. Unlike the RCRA CORRACTS/TSD TSD database, the RCRA Non-CORRACTSiTSD database does not include RCRA facilities where corrective action is required.

The Resource Conservation and Recovery Act (RCRA) Generators database, maintained by the USEPA, lists facilities that generate hazardous waste as part of their normal business practices.

Generators are listed as large, small, or conditionally exempt. Large RCRA quantity generators (LQG) produce at least 1000 kg/month of non-Generators acutely hazardous waste or 1 kg/month of acutely hazardous waste.

Small quantity generators (SQG) produce 100-1000 kg/month of non-acutely hazardous waste. Conditionally exempt small quantity generators (CESQG) are those that generate less than 100 kg/month of non-acutely hazardous waste.

The Emergency Response Notification System (ERNS) is a listing ERNS compiled by the USEPA on reported releases of petroleum and hazardous substances to the air, soil and/or water.

State The Missouri Department of Natural Resources (MDNR) maintains a SPL database of state equivalent national priority list (SPL) facilities in the 1.00 State of Missouri.

The facility is located approximately 2000 feet west-northwest and topographically, up-gradient of the subject site.

Three (3) 8000-gallon gasoline USTs were reported as being currently used at the facility.

The USTs are reported to meet the 1998 upgrade requirements for spill, overfill, and corrosion protection. Based on current regulatory status and location relative to the subject site, this facility does not appear to represent a REC at this time.

Unmapped facilities are those that do not contain sufficient address or location information to evaluate the facility listing locations relative to the site. The report listed forty-eight (48) facilities in the unmapped section. Determining the location of unmapped facilities is beyond 13

Discovery Ridge Terracon Project No. 09067718 May 31, 2006 the scope of this assessment. However, the unmapped section identified the University of Missouri - South Farm as a State Hazardous Waste Site (SHWS) facility. This facility was observed at the time of the site visit to be located approximately 1 mile to the east of the site and does not appear to represent a REC to the site based upon and topographic location and distance relative to the subject site. None of the remaining unmapped facilities were identified during the site reconnaissance as the site or in the vicinity of the site. These facilities are listed in the report in Appendix C.

4.2 Fire Department Terracon contacted the Boone County Fire District regarding the subject site. According to Doug Westoff, there are not records of hazardous materials storage or incidents regarding the site.

Compressor blowdown and staining was not observed at the time of the site visit. The compressors do not appear to represent a REC to the subject site at this time.

Hydraulic Equipment Forklifts for moving agricultural related materials and hydraulic lab testing equipment were observed on the site during the site visit. Equipment appeared in good condition and obvious indications of releases were not observed. The observed hydraulic equipment does not appear to represent a REC to the site at this time.

9 Aboveground Chemical or Waste Storage Aboveground Storaqe Tanks Two ASTs were observed behind buildings 226 and 88 during the site visit. A 1,000-gallon plastic AST half full of water was located behind building 88 and secured to a trailer. A 1 ,600-gallon empty steel AST, reported by on-site staff to be used for water storage during research activities, was located behind building 226. Two (2) propane ASTs were observed to the west of building 90. The water storage ASTs and propane ASTs do not appear to represent a REC to the site at this time.

16

Discovery Ridge Terracon Project No. 09067718 May 31, 2006 Drums. Barrels and/or Containers _>5-Gallons Terracon observed 5-gallon gasoline containers during the site visit. Most of the containers with fuel contents that were not in use with active site operations, at the time of the site visit, and appeared to be appropriately stored as to limit accidental releases in a labeled steel cabinet in building 226. Empty 5-gallon (approximate) gasoline containers and empty containers labeled coolant and solvent were observed to be stored in building 89. Evidence of releases from the empty containers was not observed at the time of the site visit.

55-gallon drums and 5-gallon buckets were observed at the civil engineering research building and building 88. The drums and buckets were labeled as containing waste oil, hydraulic fluid, and cutting oil. Minor floor staining was observed in the vicinity of waste oil drums in the civil engineering research building and is addressed below.

According to Mr. Poehlmann, waste oils from the site are removed by Safety Kleen or University Field Operations staff on an as needed basis. The observed drums and containers do not appear to represent a REC at this time.

Cleaning and/or Similar Supplies Cleaning supplies for equipment and vehicles was observed at the site. These products appeared to be stored appropriately and do not appear to represent a REC to the site.

Underground Chemical or Waste Storage, Drainage or Collection Systems Evidence of Underground Storage Tanks A 1,500-gallon temporary fiberglass UST located south of the FRB. The UST is used for storage of wastewater from the FRB until the City of Columbia installs the new sanitary sewer to the site in the September of 2006. The UST does not appear to represent a REC to the site at this time.

Sumps, Cisterns, Catch Basins and/or Dry wells According to a staff member at the FRB, a sump is associated with the floor drain in the garage area. The sump was formerly used to pump water to the MDNR permitted lagoon that is going to be closed and presumably is now used to pump to the temporary waste water UST. The sump does not appear to represent a REC to the site at this time.

Pits for the collection of animal wastes are located at buildings 90 and 91 and were used when animals were historically housed on the site. Mr. Poehlmann stated that the animal wastes were periodically flushed from the buildings. The waste collection pits do not appear to represent a REC to the site.

17

Discovery Ridge Terracon Project No. 09067718 May 31, 2006 Septic Tanks and/or Leach Fields A septic system is used for waste water from the civil engineering research building on the site. Mr. Poehlmann stated that the tank was located west of the building. The leach field was observed to be to the north of the building during the site visit. The septic system does not appear to represent a REC at the site. However, if the septic tank is to be encountered during future site development activities, it should be closed in accordance with Boone County regulations, if applicable.

Oil/Water Separators An oil/water separator is located in the garage of the FRB. The water from the separator formerly discharged to the lagoon and now discharges to the temporary UST. According to Mr. Poehlmann the oil/water separator was installed in 2002 and is cleaned out on an as needed basis. He was unaware if Safety Kleen or University Field Operations performed the separator cleanout in conjunction with the removal of other on-site waste products. A sheen was observed on the surface of the contents within the separator during the site visit and it appeared that the separator was in need of cleanout. The oil/water separator does not appear to represent a REC to the site at this time. However, Terracon recommends that a current cleanout be conducted to limit the potential of a release of petroleum products on the site.

Interior Floor Drains Interior floor drains were observed in the bathroom of the FRB and a floor drain in the garage of the FRB associated with the oil/water separator and a sump referenced above.

There was no obvious indications of staining around the floor drains at the time of the site visit. The floor drains do not appear to represent a REC to the site at this time.

Electrical Transformers/POBs Pad or Pole-Mounted Transformers and/or Capacitors Fourteen (14) pole-mounted transformers and one pad-mounted transformer were observed on the subject site. The transformers are owned and serviced by Boone Electric Cooperative. Transformers contain mineral oil, which may contain minor amounts of PCB and could be considered "PCB contaminated" (PCB content 50 to 500 ppm).

Boone Electric Cooperative maintains responsibility for the transformers, and if the transformers were "PCB contaminated," the utility company is not required to replace the transformer fluids until a release is identified. However,. no evidence of current or prior releases was observed in the vicinity of the electrical equipment during the site visit.

18

Discovery Ridge Terracon Project No. 09067718 May 31, 2006 Evidence of Releases or Potential Releases Stained Pavement or Similar Surface Minor staining of concrete flooring was observed in the civil engineering building around the waste oil drums and 5-gallon buckets. The concrete surface in this area was not cracked at the time of the site visit. The minor staining does not appear to represent a REC to the site at this time based upon small area of staining and apparent good condition of the concrete floor surface.

Construction/Demolition Debris and/or Dumped Fill Dirt Mr. Poehlmann stated that a historic lagoon on the site was filled in the past prior to regulatory requirements for formal closure sequencing. The lagoon was reportedly used to hold hog waste associated with an off-site study on swine waste and leachfields conducted in the past. Mr. Poehlmann was not aware of the exact location of the former lagoon on the site or the type of material used for backfill but he assumed that the lagoon was backfilled with its earthen berm.

Other Notable Site Features Surface Water Bodies A lake was observed on the northeastern portion and a lagoon was observed on the north-central portion of the site during the site visit. Sheens or evidence of a release were not observed on the water surface of the lagoon and lake during the site visit. According to Mr.

Poehlmann, the lagoon is in the process of closure and has a MDNR operating permit and the Missouri Department of Conservation manages the lake.

Wells According to Mr. Poehlmann, a water well is located on the site. A water well search of MDNR Geological Survey and Resource Assessment Division database information for the area of the site did not specifically identify the well and the location of the well on the site was not determined at the time of issuance of this report. The water well does not appear to represent a REC to the site at this time. However, Terracon recommends that the water well be properly abandoned according to MDNR regulations, if the well is encountered during future site development activities.

5.2.2 Interviews Conducted Associated with Site Reconnaissance The following individuals were interviewed regarding the presence or absence of the features listed in the table above. Unless otherwise noted herein, the interviewee was not aware of the listed features (identified in the Site Characteristics Table) at the site.

John Poehlmann Assistant Director of the Missouri Agricultural Station Information obtained from the above-listed interviewee is discussed in Sections 3.5 and 5.2.1 above.

6.0 ADJOINING PROPERTY RECONNAISSANCE Visual observations of adjoining properties (from site boundaries) are summarized below.

Adjoining Properties DIRECTION JDESCRIPTION North The north-adjoining property appears to consist of Ed's Mobile Home Park and Sunset Mobile Home Park to the northwest and farmland with University of Missouri storage buildings, farmland, and Sugar Grove Lane to the north and northeast.

South The south-adjoining property appears to consist of Lenoir Street, a residential house, Highway 63, Ponderosa Drive and farmland.

East The east-adjoining property appears to consist of farmland and buildings associated with the University Beef Farm.

West The west-adjoining property appears to consist of Lenoir Street, Highway 63, Ponderosa Drive and the Phillips Farm.

Obvious indications of RECs were not observed on the adjoining properties during the site reconnaissance.

7.0 ADDITIONAL SERVICES Per the agreed scope of services specified in the proposal, other additional services (e.g.

asbestos sampling, lead-based paint sampling, wetlands evaluation, lead in drinking water testing, radon testing, etc.) were not conducted.

8.0 FINDINGS, CONCLUSIONS, AND RECOMMENDATIONS 8.1 Findings and Conclusions This Phase 1 Environmental Site Assessment (ESA) of the above-referenced site was performed in accordance with our proposal dated April 6, 2006, and in general accordance with the consensus document known as ASTM E 1527-00, a guide for conducting ESAs.

Tim Bennett performed the site reconnaissance on April 18, 2006.

Discovery Ridge Terracon Project No. 09067718 May 31, 2006 The site is a 114-acre portion of the University of Missouri-South Farm which is proposed to be developed with a research park. The site is located at the approximate southwestern corner of the South Farm east of Lenoir Street and south of Sugar Grove Lane. Nine buildings associated with agricultural and engineering research and related equipment storage exist on the site. The site is generally located on the southeastern portion of Columbia, Boone County, Missouri.

A cursory summary of findings is provided below. It should be recognized that details were not included or fully developed in this section, and the report must be read in its entirety for a comprehensive understanding of the items contained herein.

• The site is located on an irregular-shaped plot of approximately 114 acres of land.

The site consists predominantly of farmland with nine buildings associated with agricultural research located on the northwestern portion of the site and a lake. The site is owned by the University of Missouri. According to Mr. John Poehlmann, Assistant Director of University of Missouri Agricultural Station and superintendent of the site, the site currently and historically has been used for agricultural research and teaching which included maize genetics crop research, swine nutrition, beef cattle management and grazing, agricultural equipment development, and cropping for grain, silage and uptake of nutrients from lagoon application.

• Observations made during Terracon's reconnaissance of the subject site included, but was not limited to 55-gallon drums, 5-gallon containers; an oil/water separator and sump associated with an indoor floor drain; aboveground storage tanks (ASTs) for water; a temporary underground storage tank (UST) for collection of wastewater; electrical transformers; a lake and a lagoon. Observations did not indicate recognized environmental conditions (RECs) associated with these features at the time of the site reconnaissance.

• Based on a review of historical information including, historical topographic maps, aerial photographs, and interviews, the subject site appears to have been developed by at least 1935 with apparent farmstead buildings. The development of the current-day buildings on the site appears to have begun between 1939 and 1948. The lake on the site appears to have been constructed between approximately 1948 and 1959 and the current-day lagoon constructed between 1974 and 1981. A review of registered water well information provided by the Missouri Department of Natural Resources (MDNR)-Geological Survey and Resource Assessment Division (GSRAD) did not identify a water well which is reportedly on the site at an unknown location. Development of the surrounding areas appears to have begun by at least 1935 with the development of current-day Highway 63 to the west and south and homes and buildings associated with surrounding farmland to the north, south, and 21

Discovery Ridge Terracon Project No. 09067718 May 31, 2006 west of the subject site. The development of the current-day Ed's Mobile Home Park and Sunset Mobile Home Park northwest of the site began between approximately 1948 and 1959.

• The current-day adjoining properties of the subject site consist of the following:

• Ed's Mobile Home Park and Sunset Mobile Home Park, farmland with University of Missouri storage buildings, and Sugar Grove Lane, to the north,

• Farmland and buildings associated with the University Beef Farm to the east,

• Lenoir Street, a residential house, Highway 63, Ponderosa Drive and farmland to the south, and

• Lenoir Street, Highway 63, Ponderosa Drive and the Phillips Farm to the west.

The adjoining properties do not appear to represent a REC to the subject site at this time.

• The regulatory database review identified no Environmental Protection Agency (EPA) facilities, and one (1) MDNR Underground Storage Tank (UST) facility within the specified search radii. Based on the regulatory status and topographic distance relative to the subject site, this facility does not appear to represent a REC to the subject site.

8.2 Recommendations Based on the Scope of Services for this assessment, Terracon did not identify conditions which, in our opinion, require additional investigation at this time. However;

• Terracon recommends a current cleanout of the oil/water separator in the garage of the USDA Field Research Building (FRB).

• Water wells may provide a direct migration pathway for contaminants to reach aquifers underlying a site, and therefore become a source of environmental concern. If the well on the site is encountered during the proposed site activities, Terracon recommends that the water well be properly abandoned according to MDNR regulations. Proper abandonment of water wells should be performed by a water well driller licensed with the State of Missouri, and requires notification to MDNR prior to abandonment.

• If the septic tank is to be encountered during future site development activities, it should be closed in accordance with Boone County regulations, if applicable.

Archived status indicates that, to the best of EPA's knowledge, assessment at a site has been completed and that EPA has determined no further steps will be taken to list this site on the National Priorities List (NPL), unless information indicates this decision was not appropriate or other considerations require a recommendation for listing at a later time.

This decision does not necessarily mean that there is no hazard associated with a given site; it only means that, based upon available information, the location is not judged to be a potential NPL site.

RCRAInfo replaces the data recording and reporting abilities of the Resource Conservation and Recovery Information System (RCRIS).

The database includes selective information on sites which generate, transport, store, treat and/or dispose of hazardous waste as defined by the Resource Conservation and Recovery Act (RCRA). Conditionally exempt small quantity generators (CESOGs) generate less than 100 kg of hazardous waste, or less than 1 kg of acutely hazardous waste per month. Small quantity generators (SQGs) generate between 100 kg and 1,000 kg of hazardous waste per month. Large quantity generators (LQGs) generate over 1,000 kilograms (kg) of hazardous waste, or over 1 kg of acutely hazardous waste per month. Transporters are individuals or entities that move hazardous waste from the generator off-site to a facility that can recycle, treat, store, or dispose of the waste. TSDFs treat, store, or dispose of the waste.

GOVERNMENT RECORDS SEARCHED I DATA CURRENCY TRACKING Included in the listing are brownfields properties addresses by Cooperative Agreement Recipients and brownfields properties addressed by Targeted Brownfields Assessments. Targeted Brownfields Assessments-EPA's Targeted Brownfields Assessments (TBA) program is designed to help states, tribes, and municipalities--especially those without EPA Brownfields Assessment Demonstration Pilots--minimize the uncertainties of contamination often associated with brownfields. Under the TBA program, EPA provides funding and/or technical assistance for environmental assessments at brownfields sites throughout the country. Targeted Brownfields Assessments supplement and work with other efforts under EPA's Brownfields Initiative to promote cleanup and redevelopment of brownfields. Cooperative Agreement Recipients-States, political subdivisions, territories, and Indian tribes become Brownfields Cleanup Revolving Loan Fund (BCRLF) cooperative agreement recipients when they enter into BCRLF cooperative agreements with the U.S. EPA. EPA selects BCRLF cooperative agreement recipients based on a proposal and application process. BCRLF cooperative agreement recipients must use EPA funds provided through BCRLF cooperative agreement for specified brownfields-related cleanup activities.

Manufactured gas sites were used in the United States from the 1800's to 1950's to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production, such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds are potentially hazardous to human health and the environment. The byproduct from this process was frequently disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil and groundwater contamination.

SUMMARY

This Phase I ESA was performed in accordance with our proposal dated December 15, 2010, and was conducted consistent with the procedures included in ASTM E 1527-05, Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process. The ESA was conducted under the supervision or responsible charge of Timothy L. Bennett, R.G., environmental professional. Adam J White performed the site reconnaissance on January 21, 2011 and February 23, 2011.

A cursory summary of findings is provided below. It should be recognized that details were not included or fully developed in this section, and the report must be read in its entirety for a comprehensive understanding of the items contained herein.

• The site is located along Discovery Ridge Parkway and Discovery Drive within the University of Missouri, Discovery Ridge Research Park, Columbia, Boone County, Missouri. The site is an approximate 120-acre tract of land, improved with three machine shed structures located on the northern portion, occupied by the University of Missouri-Genetics Farm, and a Quonset hut located on the western portion occupied by the United States Department of Agricultural (USDA). The on-site structures are utilized for the storage of multiple pieces of research equipment. The remainder of the site consists of vacant undeveloped land utilized for row crop production, and livestock pasture with portions developed as graded lots associated with the current-day Discovery Ridge Research Park.

• On-site features observed during the site reconnaissance included interior floor drains within the large machine shed, four tractors, eight pad mounted transformers, three inactive pole-mounted transformer, a septic system, an approximately 500-gallon propane AST, fill dirt, an air compressor and an intermittent stream. On-site RECs were not identified based on visual findings during the site reconnaissance.

• Based on review of the historical information, the site has predominately been vacant farmland consisting of both row crop production and livestock pasture from at least 1934 to 2006. The western portion of the site has been utilized as a research park development from approximately 2006 to present-day. Additionally, the eastern portion of the site has always been utilized as farmland and livestock pasture land.

The northern portion of the site is currently utilized as a University of Missouri plant genetic research farm. A residential structure was located at the Genetics Farm, on the northern portion of the site from approximately 1945 to 2001 at which time the residential structure was demolished. Multiple small machine shed structures have been located at the Genetics Farm, on the northern portion of the site from at least Reliable

• Terracon Project No. 09117701 1956 to the mid 2000s with two small machine structures still present on-site. The large machine shed structure located at the Genetics Farm was placed on-site in approximately 2007. A Quonset hut structure utilized by the USDA has been located on the western portion of the site from approximately 1965 to present-day. A residential structure was located on the western portion of the site, east of the current-day on-site Quonset hut from approximately 1945 to approximately the I1980s. A small log cabin type structure was located on the central portion of the site from approximately 1945 to 1980. Terracon did not identify RECs for the site based on the historical use of the site or adjoining properties.

The current-day adjoining properties of the subject site consist of the following:

• Sugar Grove Road, RI Lake, and livestock pasture land, followed by row crop farmland and livestock pasture land to the north;

• Highway 63, followed by grass and tree covered land with Phillips Lake to the south;

• A trailer park, followed by an elderly care facility to the northwest and Highway 63 to the west; and

• A residential structure, a barn, wooded land and livestock pasture land, followed by pasture land associated with the University of Missouri Beef Farm to the east.

Collective Adjoining - Properties encompassed by the site

• ABC Laboratories encompassed by Lot 5, Lot 17, Lot 18, Lot 2, and Lot 6;

• Radii with pad-mounted transformer encompassed by Lot 2, Lot 8, and Lot 15;

• Stormwater drainage easement encompassed by Lot 2, Lot 7, and Lot 8;

• A City of Columbia, sanitary sewer pump station, with diesel generator encompassed on the southwestern portion of Lot 9.

A City of Columbia sanitary sewer pump station with a diesel generator was observed located on a collective adjoining property on the southwestern portion of Lot 9. The City of Columbia sanitary sewer pump station currently does not represent a REC to the site due to duration of time located on and encompassed by Lot 9.

Indications of RECs were not observed with the current-day adjoining and collective adjoining properties.

• The regulatory review identified one Missouri Department of Natural Resources facility within the specified search distance; however, the facility is not a REC due to regulatory status, and duration of time located within the vicinity of the site.

Additionally an Orphan facility was identified located on the north adjoining property.

Terracon Project No. 09117701 The local agency inquiries for environmental records did not reveal RECs in connection with the site from the agencies that have responded by the issuance of this report.

The following previous environmental report associated with portions of the current-day Discovery Ridge Research Park and its associated collective adjoining properties, was provided by the University of Missouri for review: Phase I Environmental Site Assessment Discovery Ridge, prepared by Terracon, prepared for University of Missouri, Terracon proiect number 09067718, dated May 31, 2006. The 2006 Terracon ESA report did not identify RECs associated with the subject site; however did recommend the cleanout of the oil/water separator in the garage of the USDA Field Research Building (FRB), and if encountered during proposed site activities the proper abandonment of the water well and the closure of the septic tank located within the vicinity of the current-day ABC Laboratories' facility.

The oil/water separator, water well and septic tank discussed within Terracon's 2006 ESA report were identified as located on the site's collective adjoining properties.

• The following previous geotechnical engineering report associated with Discovery Ridge was provided by the University of Missouri for review: Geotechnical Engineering Report Discovery Ridge Lots 2. 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, and 18, prepared by Terracon, prepared for University of Missouri.

Terracon proiect number 09105094, dated February 17, 2011. The 2011 Terracon geotechnical engineering report stated that nine soil borings were advanced at the site. According to the geotechnical report, fill soils were encountered in borings B-3 and B-4 on Lot 2 and Lot 8, respectively. It was noted that the material was placed as part of a mass grading in 2008 and that Terracon was onsite to observe and test the density and moisture during the placement of the engineered fill material. Additionally the report indicated that historically a pond may have been present in the vicinity of Lot 16 and on the northeastern portion of Lot 2.

Typically on-site depth to groundwater was encountered between 12 feet and 18.5 feet below existing grade.

• Pursuant to the client's request, an agency file review was conducted to identify the potential occurrence of cultural resources on the site. The Section 106 Review form, signed by Mark Miles, Deputy State Historic Preservation Officer, dated March 7, 2011 states that "an adequate cultural resource survey of the project area has been previously conducted. It has been determined that for the proposed undertaking there will be no historic properties affected."

1.2 Scope of Services This Phase I ESA was performed in accordance with our proposal dated December 15, 2010, and was conducted consistent with the procedures included in ASTM E 1527-05, Standard Practice for Environmental Site Assessments: Phase / Environmental Site Assessment Process. The purpose of this ESA was to assist the client in developing information to identify RECs in connection with the site as reflected by the scope of this report. This purpose was undertaken through user-provided information, a regulatory database review, historical and physical records review, interviews, including local government inquiries, as applicable, and a visual noninvasive reconnaissance of the site and adjoining properties. Limitations, ASTM deviations, and significant gaps (if identified) are evident from reviewing the applicable scope of services and the report text.

1.3 Standard of Care This ESA was performed in accordance with generally accepted practices of this profession, undertaken in similar studies at the same time and in the same geographical area. We have endeavored to meet this standard of care, but may be limited by conditions encountered during performance, a client-driven scope of work, or inability to review information not received by the report date.

Phase I ESAs, such as the one performed at this site, are of limited scope, are noninvasive and cannot eliminate the potential that hazardous, toxic, or petroleum substances are present or have been released at the site beyond what is identified by the limited scope of this ESA. In conducting the limited scope of services described herein, certain sources of information and public records were not reviewed. It should be recognized that environmental concerns may be documented in public records that were not reviewed. No ESA can wholly eliminate uncertainty regarding the potential for RECs in connection with a property. Performance of this practice is intended to reduce, but not eliminate, uncertainty regarding the potential for RECs. No warranties, express or implied, are intended or made.

The limitations herein must be considered when the user of this report formulates opinions as to risks associated with the site or otherwise uses the report for any other purpose.

These risks may be further evaluated - but not eliminated - through additional research or assessment. We will, upon request, advise you of additional research or assessment options that may be available and associated costs.

1.4 Additional .Scope Limitations, ASTM Deviations and Significant Data Gaps Based upon the agreed-on scope of services, this ESA did not include subsurface or other invasive assessments, business environmental risk evaluations, or other services not particularly identified and discussed herein. Reasonable attempts were made to obtain information within the scope and time constraints set forth by the client; however, in some instances, information requested is not, or was not, received by the issuance date of the report. Consideration of such information is beyond the scope of this assessment.

Information obtained for this ESA was received from several sources that we believe to be reliable; nonetheless, the authenticity or reliability of these sources cannot and is not warranted hereunder. This ESA was further limited by the following:

• Credentials of the company (Statement of Qualifications) have not been included in this report but are available upon request.

• Pertinent documents are referred to in the text of this report, and a separate reference section has not been included.

• At the time of the February 23, 2011 site reconnaissance, the two small machine shed type storage structures located on Lot 17 were locked and inaccessible.

• At the time of the January 21, 2011 site reconnaissance, the site was covered with snow making the exterior surface of the site unobservable.

The oil/water separator, water well and septic tank discussed within Terracon's 2006 ESA report were identified as located on the site's collective adjoining properties.

A review of readily available historical information revealed that the development of the current-day buildings on the site appeared to have begun between 1939 and 1948. The lake on the site appeared to have been constructed between approximately 1948 and 1959 and the lagoon constructed between 1974 and 1981.

The regulatory review identified no USEPA facilities and one MDNR facility within the vicinity of the site. Also identified in the regulatory database report was an orphan facility identified as the University of Missouri-South Farm. The University of Missouri-South Farms facility was identified as a State Hazardous Waste Site (SHWS). This facility was observed at the time of the site visit to be located approximately 1 mile east of the site. The regulatory review and agency inquires did not reveal RECs associated with the site.

Terracon interviewed Mr. John Poehlmann regarding the site. Mr. Poehlmann is the Assistant Director of the Missouri Agricultural Experiment Station and superintendent of the University of Missouri-South Farms of which the site is located within. Mr. Poehlmann stated that the site currently and historically has been used for agricultural research and teaching which included maize genetics crop research, swine nutrition, beef cattle management and grazing, agricultural equipment development and cropping for grain silage and uptake of nutrients from lagoon application. To Mr. Poehlmann's knowledge, the nine buildings located on the site were constructed between the. 1970's and approximately.2002.

According to Mr. Poehlmann, there are pits for the collection of animal waste beneath a building which formerly housed sheep and swine. The wastes were surface and injection applied as plant nutrients. The on-site lagoon operated under the MDNR permit MO-G01 0024. Mr. Poehlmann stated that a well is located on the site. The exact location of the well was not known. However, the well was installed in the approximate 1950's and reported to be abandoned. Mr. Poehlmann has no knowledge of any aboveground or underground storage tanks for chemicals or petroleum, past use, treatment, disposal or generation of hazardous materials or petroleum products associated with the subject site.

APPENDIX B Description of Terms and Acronyms

Description of Selected General Terms and Acronyms TermlAcronym Description Asbestos Containing Material. Asbestos is a naturally occurring mineral, three varieties of which (chrysotile, amosite, crocidolite) have been commonly used as fireproofing or as binding agents in construction materials. Inhalation of asbestos fibers has been documented to cause asbestosis (scarring of the lung), lung cancer, and mesothelioma (a cancer of the chest wall lining).

Most Federal and State agencies define ACM as a material containing more that one (1) percent asbestos, although some states, such as California, define ACM as material containing 0.1% or more asbestos. In order to determine the ACM status of suspect building materials, a minimum number of samples must be collected and analyzed, depending on the type and quantity of the suspect material. A suspect material can only be confirmed as non-ACM when analytical results of all required samples are below applicable regulatory limits. Asbestos concentrations are generally determined using polarized light microscopy or transmission electron microscopy. An asbestos containing ACM material may be classified as either friable or non-friable. Friable materials are those that, when dry, can be crumbled, pulverized, or reduced to powder by hand pressure.

Non-friable ACM are materials in which the asbestos fibers are more firmly bound in a matrix of tar, plastic or other such material, and which have a lower potential for asbestos fiber release.

Federal and State regulations require that that an asbestos survey be performed prior to renovation, dismantling, demolition or other activities that may disturb suspect or confirmed ACM unless such materials are removed as ACM prior to planned disturbances. ACM removal may also be required if confirmed ACM becomes damaged, or if renovation or demolition activities could result in damage to confirmed or suspect ACM. Depending upon the quantity, notification to Federal or State regulatory agencies may be required prior to ACM removal (abatement) operations. Abatement of friable or potentially friable ACM must be performed by a licensed abatement contractor in accordance with applicable federal, state, or local regulations. OSHA worker protection regulations will also apply.

AHERA Asbestos Hazard Emergency Response Act Above Ground Storage Tanks. ASTs are generally described as storage tanks less than 10% of which are below ground (i.e., buried). Tanks located in a basement, but not AST buried, are also considered ASTs. Whether, and the extent to which, an AST is regulated, is determined on a case-by-case basis and depends upon tank size, its contents and the jurisdiction of its location.

AULs Activity and Use Limitations BGS Below Ground Surface BTEX Benzene, Toluene, Ethyl benzene, and Xylenes. BTEX are VOC components found in gasoline and commonly used as analytical indicators of a petroleum hydrocarbon release.

PHASE I ENVIRONMENTAL SITE ASSESSMENT DISCOVERY RIDGE EAST OF LENOIR STREET AND SOUTH OF SUGAR GROVE LANE COLUMBIA, BOONE COUNTY, MISSOURI Project No. 09067718

• May 31, 2006 EXECUTIVE

SUMMARY

This Phase I Environmental Site Assessment (ESA) of the above-referenced site was performed in accordance with our proposal dated April 6, 2006, and in general accordance with the consensus document known as ASTM E 1527-00, a guide for conducting ESAs.

Tim Bennett performed the site reconnaissance on April 18, 2006.

The site is a 114-acre portion of the University of Missouri-South Farm which is proposed to be developed with a research park. The site is located at the approximate southwestern corner of the South Farm east of Lenoir Street and south of Sugar Grove Lane. Nine buildings associated with agricultural and engineering research and related equipment storage exist on the site. The site is generally located on the southeastern portion of Columbia, Boone County, Missouri.

A cursory summary of findings is provided below. It should be recognized that details were not included or fully developed in this section, and the report must be read in its entirety for a comprehensive understanding of the items contained herein.

• The site is located on an irregular-shaped plot of approximately 1 14 acres of land.

The site consists predominantly of farmland with nine buildings associated with agricultural research located on the northwestern portion of the site and a lake. The site is owned by the University of Missouri. According to Mr. John Poehlmann, Assistant Director of University of Missouri Agricultural Station and superintendent of the site, the site currently and historically has been used for agricultural research and teaching which included maize genetics crop research, swine nutrition, beef cattle management and grazing, agricultural equipment development, and cropping for grain, silage and uptake of nutrients from lagoon application.

• Observations made during Terracon's reconnaissance of the subject site included, but was not limited to 55-gallon drums, 5-gallon containers; an oil/water separator and sump associated with an indoor floor drain; aboveground storage tanks (ASTs) for water; a temporary underground storage tank (UST) for collection of wastewater; electrical transformers; a lake and a lagoon. Observations did not indicate iii

EXECUTIVE

SUMMARY

(cont.) Trao Terracon recognized environmental conditions (RECs) associated with these features at the time of the site reconnaissance.

• Based on a review of historical information including, historical topographic maps, aerial photographs, and interviews, the subject site appears to have been developed by at least 1935 with apparent farmstead buildings. The development of the current-day buildings on the site appears to have begun between 1939 and 1948. The lake on the site appears to have been constructed between approximately 1948 and 1959 and the current-day lagoon constructed between 1974 and 1981. A review of registered water well information provided by the Missouri Department of Natural Resources (MDNR)-Geological Survey and Resource Assessment Division (GSRAD) did not identify a water well which is reportedly on the site at an unknown location. Development of the surrounding areas appears to have begun by at least 1935 with the development of current-day Highway 63 to the west and south and homes and buildings associated with surrounding farmland to the north, south, and west of the subject site. The development of the current-day Ed's Mobile Home Park and Sunset Mobile Home Park northwest of the site began between approximately 1948 and 1959.

• The current-day adjoining properties of the subject site consist of the following:

• Ed's Mobile Home Park and Sunset Mobile Home Park, farmland with University of Missouri storage buildings, and Sugar Grove Lane, to the north,

• Farmland and buildings associated with the University Beef Farm to the east,

• Lenoir Street, a residential house, Highway 63, Ponderosa Drive and farmland to the south, and

• Lenoir Street, Highway 63, Ponderosa Drive and the Phillips Farm to the west.

The adjoining properties do not appear to represent a REC to the subject site at this time.

• The regulatory database review identified no Environmental Protection Agency (EPA) facilities, and one (1) MDNR Underground Storage Tank (UST) facility within the specified search radii. Based on the regulatory status and topographic distance relative to the subject site, this facility does not appear to represent a REC to the subject site.

Recommendations Based on the Scope of Services for this assessment, Terracon did not identify conditions which, in our opinion, require additional investigation at this time. However;

• Terracon recommends a current cleanout of the oil/water separator in the garage of the USDA Field Research Building (FRB).

iv

EXECUTIVE

SUMMARY

(cont.) Terracon Trao

• Water wells may provide a direct migration pathway for contaminants to reach aquifers underlying a site, and therefore become a source of environmental concern. If the well on the site is encountered during the proposed site activities, Terracon recommends that the water well be properly abandoned according to MDNR regulations. Proper abandonment of water wells should be performed by a water well driller licensed with the State of Missouri, and requires notification to MDNR prior to abandonment.

• If the septic tank is to be encountered during future site development activities, it should be closed in accordance with Boone County regulations, if applicable.

1.0 INTRODUCTION

1.1 Site Description Site Description Site Name Discovery Ridge East of Lenoir Street and south of Sugar Grove Lane, Columbia, Boone Site Location/Address CutMsor Land Area Approximately 114 acres Additional Site The subject site consists of predominantly farmland with a lake, lagoon, Improvements and nine buildings located on the northwestern portion of the site.

The site location is depicted on Figure 1 of Appendix A, which was reproduced from a portion of the Columbia, Missouri Quadrangle, United States Geological Survey (USGS) 7.5 minute series topographic map. A Site Diagram of the site and adjoining properties is included as Figure 2 of Appendix A. Acronyms and terms used in this report are described in Appendix E.

1.2 Scope of Work This Environmental Site Assessment (ESA) was performed in accordance with our proposal dated April 6, 2006 and in general accordance with the consensus document known as ASTM E 1527-00, a guide for conducting ESAs. The purpose of this ESA was to assist the client in developing information to identify recognized environmental conditions (RECs) in connection with the site as reflected by the scope of this report. This purpose was undertaken through a regulatory database review, historical and physical records review, interviews, including local government inquiries, as applicable, and a visual noninvasive reconnaissance of the site and adjoining properties. Limitations and ASTM deviations are evident from reviewing the applicable scope of services and the report text.

1.3 Standard of Care This ESA was performed in accordance with generally accepted practices of this profession, undertaken in similar studies at the same time and in the same geographical area. We have 1

Discovery Ridge Terracon Project No. 09067718 May 31, 2006 endeavored to meet this standard of care, but may be limited by conditions encountered during performance, a client-driven scope of work, or inability to review information not received by the report date.

Phase I ESAs, such as the one performed at this site, are of limited scope, are noninvasive and cannot eliminate the potential that hazardous, toxic, or petroleum substances are present or have been released at the site beyond what is identified by the limited scope of this ESA. In conducting the limited scope of services described herein, certain sources of information and public records were not reviewed. It should be recognized that environmental concerns may be documented in public records that were not reviewed. No ESA can wholly eliminate uncertainty regarding the potential for recognized environmental conditions in connection with a property. Performance of this practice is intended to reduce, but not eliminate, uncertainty regarding the potential for recognized environmental conditions.. No warranties, express or implied, are intended or made. The limitations herein must be considered when the user of this report formulates opinions as to risks associated with the site or otherwise uses the report for any other purpose. These risks may be further evaluated - but not eliminated - through additional research or assessment. Terracon will, upon request, advise you of additional research or assessment options that may be available and associated costs.

1.4 Additional Scope Limitations and ASTM Exceptions eased upon the agreed-on scope of services, this ESA did not include subsurface or other invasive assessments, business environmental risk evaluations, or other services not particularly identified and discussed herein. Reasonable attempts were made to obtain information within the scope and time constraints set forth by the client; however, in some instances, information requested is not, or was not, received by the issuance date of the report. Consideration of such information is beyond the scope of this assessment.

Information obtained for this ESA was received from several sources that we believe to be reliable; nonetheless, the authenticity or reliability of these sources cannot and is not warranted hereunder. This ESA was further limited by the following:

• Credentials of the environmental assessors (resumes) and of the company (Statement of Qualifications) have not been included in this report but are available upon request.

This report represents our service to you as of the report date and constitutes our final document; its text may not be altered after final issuance. Findings in this report are based upon the site's current utilization, information derived from the most recent reconnaissance and from other activities described herein; such information is subject to change. Certain

Discovery Ridge Terracon Project No. 09067718 May 31, 2006 indicators of the presence of hazardous substances or petroleum products may have been latent, inaccessible, unobservable, or not present during the most recent reconnaissance and may subsequently become observable (such as after site renovation or development).

Further, these services are not to be construed as legal interpretation or advice.

1.5 Reliance This ESA report is prepared for the exclusive use and reliance of the University of Missouri.

Use or reliance by any other party is prohibited without the written authorization of the University of Missouri and Terracon.

Reliance on the ESA by the client and all authorized parties will be subject to the terms, conditions and limitations stated in the proposal, ESA report, and Terracon's Agreement for Services. The limitation of liability defined in the Agreement for Services is the aggregate limit of Terracon's liability to the client and all relying parties.

3.4 Ownership Information At the direction of the client, a title search was not included as part of the scope of services.

3.5 Historical Interviews Terracon interviewed Mr. John Poehlmann regarding the subject site. Mr. Poehlmann is the Assistant Director of the Missouri Agricultural Experiment Station and superintendent of the University of Missouri (University) South Farm of which the subject site is located within. Mr.

Poehlmann has been associated with the site between 1983 through 1986 and since January of 2000. To Mr. Poehlmann's knowledge, the site was previously owned by unspecified multiple landowners previous to ownership by the University. Mr. Poehlmann stated that the site currently and historically has been used for agricultural research and teaching which included maize genetics crop research, swine nutrition, beef cattle 9

Discovery Ridge Terracon Project No. 09067718 May 31, 2006 management and grazing, agricultural equipment development, and cropping for grain, silage and uptake of nutrients from lagoon application. To Mr. Poehlmann's knowledge, past tenants of the site have included USDA-ARS and Animal Sciences faculty. Mr.

Poehlmann stated that the current and historic uses of the surrounding property has been for agricultural research in beef, corn genetics, entomology, atmospheric science, and a Missouri Department of Conservation fishing lake.

Mr. Poehlmann stated that there are nine structures on the site that are associated with research and development for civil engineering and agriculture. To Mr. Poehlmann's knowledge, the buildings were constructed between thie 1970's and approximately 2002.

According to Mr. Poehlmann, waste water from all buildings except the civil engineering research building discharge to the on-site lagoon until recently. The civil engineering building waste water is handled by septic system located to the west of the building.

Currently the waste water from the USDA Field Research Building (FRB) is being collected in a 1500-gallon temporary underground storage tank (UST) until the upcoming City of Columbia sewer system is installed. Mr. Poehlmann stated that an oil/water separator is located beneath a floor drain in the FRB and is cleaned out on an as needed basis.

According to Mr. Poehlmann, there are pits for the collection of animal waste beneath buildings which formerly housed sheep and swine. The wastes were surface and injection applied as plant nutrients. The lagoon operates under MDNR permit MO-G010024. Mr.

Poehlmann stated that a well is located on the site. The exact location was not known.

However, the well was installed in the approximate 1950's and reported to be abandoned and have a steel cap welded to the top of the casing. The well was reportedly used to provide potable water for livestock. According to Mr. Poehlmann waste oil from the site is collected by the University Field Operations staff or Safety Kieen. Mr. Poehlmann stated that solvents, paints, oils, fuels, and lubricants typically used for agriculture and research are present on the site. According to Mr. Poehlmann, the site is inspected at least twice annually or more to identify unlabelled containers and unknown substances. Mr.

Poehlmann was aware of hydraulic equipment at the site which included portable testing equipment at the civil engineering building and forklifts used by the USDA. Mr. Poehlmann has no knowledge of any aboveground or underground storage tanks for chemicals or petroleum, past use, treatment, disposal or generation of hazardous materials or petroleum products, polychlorinated biphenyl (PCB) equipment, solid waste disposal, or any pending, threatened, or past litigation, administrative proceedings, violations of environmental laws, or possible litigation relating to hazardous substances or petroleum products associated with the subject site.

Discovery Ridge Terracon Project No. 09067718 May 31, 2006 3.6 Prior Report Review Previous ESA or geotechnical reports of environmental significance, for the subject site, were not provided by the client to Terracon for review.

4.0 RECORDS REVIEW The United States EPA and State of Missouri database information was provided by EDR, a contract information services company, for indications of environmental concern on and in the vicinity of the site. Information in this section is subject to the accuracy of the data provided by the information services company and the date at which the information is updated, and the scope herein did not include confirmation of facilities listed as "unmappable" by regulatory databases.

In some of the following subsections, the words up-gradient, cross-gradient and down-gradient refer to the topographic gradient in relation to the site. As stated previously, the groundwater flow direction and the depth to shallow groundwater, if present, would likely vary depending upon seasonal variations in rainfall and the depth to the soil/bedrock interface. Without the benefit of on-site groundwater monitoring wells surveyed to a datum, groundwater depth and flow direction beneath the site cannot be ascertained.

4.1 Federal and State Databases Listed below are the names and number of facilities identified on federal and state databases within the indicated search areas. Database definition, descriptions, and the database search report are included in Appendix C.

Database {Description Federal and State Databases Rdu Facilities Federal The National Priorities List (NPL) is the USEPA's database of NPL uncontrolled or abandoned hazardous waste facilities that have been 1.0 0 listed for priority remedial actions under the Superfund Program.

The CERCLIS database is a compilation of facilities which the CERCLIS/ USEPA has investigated or is currently investigating for a release or 0.0 NFRAP threatened release of hazardous substances pursuant to the Comprehensive Environmental Response, Compensation and 11

Discovery Ridge Terracon Project No. 09067718 May 31, 2006 Databaser Description Liability Act (CERCLA) of 1980. NFRAP (No Further Remedial Action Planned) refers to facilities that have been removed and archived from its inventory of CERCLA sites.

The USEPA maintains a database of RCRA facilities associated with RCRA treatment, storage, and disposal (TSD) of hazardous materials that CORRACTS/ are undergoing "corrective action". A "corrective action" order is TSD issued when there has been a release of hazardous waste or constituents into the environment from a RCRA facility.

The RCRA Non-CORRACTS/TSD Database is a compilation by the RCRA Non- USEPA of facilities that report storage, transportation, treatment, or CORRACTSI disposal of hazardous waste. Unlike the RCRA CORRACTS/TSD TSD database, the RCRA Non-CORRACTSiTSD database does not include RCRA facilities where corrective action is required.

The Resource Conservation and Recovery Act (RCRA) Generators database, maintained by the USEPA, lists facilities that generate hazardous waste as part of their normal business practices.

Generators are listed as large, small, or conditionally exempt. Large RCRA quantity generators (LQG) produce at least 1000 kg/month of non-Generators acutely hazardous waste or 1 kg/month of acutely hazardous waste.

Small quantity generators (SQG) produce 100-1000 kg/month of non-acutely hazardous waste. Conditionally exempt small quantity generators (CESQG) are those that generate less than 100 kg/month of non-acutely hazardous waste.

The Emergency Response Notification System (ERNS) is a listing ERNS compiled by the USEPA on reported releases of petroleum and hazardous substances to the air, soil and/or water.

State The Missouri Department of Natural Resources (MDNR) maintains a SPL database of state equivalent national priority list (SPL) facilities in the 1.00 State of Missouri.

The facility is located approximately 2000 feet west-northwest and topographically, up-gradient of the subject site.

Three (3) 8000-gallon gasoline USTs were reported as being currently used at the facility.

The USTs are reported to meet the 1998 upgrade requirements for spill, overfill, and corrosion protection. Based on current regulatory status and location relative to the subject site, this facility does not appear to represent a REC at this time.

Unmapped facilities are those that do not contain sufficient address or location information to evaluate the facility listing locations relative to the site. The report listed forty-eight (48) facilities in the unmapped section. Determining the location of unmapped facilities is beyond 13

Discovery Ridge Terracon Project No. 09067718 May 31, 2006 the scope of this assessment. However, the unmapped section identified the University of Missouri - South Farm as a State Hazardous Waste Site (SHWS) facility. This facility was observed at the time of the site visit to be located approximately 1 mile to the east of the site and does not appear to represent a REC to the site based upon and topographic location and distance relative to the subject site. None of the remaining unmapped facilities were identified during the site reconnaissance as the site or in the vicinity of the site. These facilities are listed in the report in Appendix C.

4.2 Fire Department Terracon contacted the Boone County Fire District regarding the subject site. According to Doug Westoff, there are not records of hazardous materials storage or incidents regarding the site.

Compressor blowdown and staining was not observed at the time of the site visit. The compressors do not appear to represent a REC to the subject site at this time.

Hydraulic Equipment Forklifts for moving agricultural related materials and hydraulic lab testing equipment were observed on the site during the site visit. Equipment appeared in good condition and obvious indications of releases were not observed. The observed hydraulic equipment does not appear to represent a REC to the site at this time.

9 Aboveground Chemical or Waste Storage Aboveground Storaqe Tanks Two ASTs were observed behind buildings 226 and 88 during the site visit. A 1,000-gallon plastic AST half full of water was located behind building 88 and secured to a trailer. A 1 ,600-gallon empty steel AST, reported by on-site staff to be used for water storage during research activities, was located behind building 226. Two (2) propane ASTs were observed to the west of building 90. The water storage ASTs and propane ASTs do not appear to represent a REC to the site at this time.

16

Discovery Ridge Terracon Project No. 09067718 May 31, 2006 Drums. Barrels and/or Containers _>5-Gallons Terracon observed 5-gallon gasoline containers during the site visit. Most of the containers with fuel contents that were not in use with active site operations, at the time of the site visit, and appeared to be appropriately stored as to limit accidental releases in a labeled steel cabinet in building 226. Empty 5-gallon (approximate) gasoline containers and empty containers labeled coolant and solvent were observed to be stored in building 89. Evidence of releases from the empty containers was not observed at the time of the site visit.

55-gallon drums and 5-gallon buckets were observed at the civil engineering research building and building 88. The drums and buckets were labeled as containing waste oil, hydraulic fluid, and cutting oil. Minor floor staining was observed in the vicinity of waste oil drums in the civil engineering research building and is addressed below.

According to Mr. Poehlmann, waste oils from the site are removed by Safety Kleen or University Field Operations staff on an as needed basis. The observed drums and containers do not appear to represent a REC at this time.

Cleaning and/or Similar Supplies Cleaning supplies for equipment and vehicles was observed at the site. These products appeared to be stored appropriately and do not appear to represent a REC to the site.

Underground Chemical or Waste Storage, Drainage or Collection Systems Evidence of Underground Storage Tanks A 1,500-gallon temporary fiberglass UST located south of the FRB. The UST is used for storage of wastewater from the FRB until the City of Columbia installs the new sanitary sewer to the site in the September of 2006. The UST does not appear to represent a REC to the site at this time.

Sumps, Cisterns, Catch Basins and/or Dry wells According to a staff member at the FRB, a sump is associated with the floor drain in the garage area. The sump was formerly used to pump water to the MDNR permitted lagoon that is going to be closed and presumably is now used to pump to the temporary waste water UST. The sump does not appear to represent a REC to the site at this time.

Pits for the collection of animal wastes are located at buildings 90 and 91 and were used when animals were historically housed on the site. Mr. Poehlmann stated that the animal wastes were periodically flushed from the buildings. The waste collection pits do not appear to represent a REC to the site.

17

Discovery Ridge Terracon Project No. 09067718 May 31, 2006 Septic Tanks and/or Leach Fields A septic system is used for waste water from the civil engineering research building on the site. Mr. Poehlmann stated that the tank was located west of the building. The leach field was observed to be to the north of the building during the site visit. The septic system does not appear to represent a REC at the site. However, if the septic tank is to be encountered during future site development activities, it should be closed in accordance with Boone County regulations, if applicable.

Oil/Water Separators An oil/water separator is located in the garage of the FRB. The water from the separator formerly discharged to the lagoon and now discharges to the temporary UST. According to Mr. Poehlmann the oil/water separator was installed in 2002 and is cleaned out on an as needed basis. He was unaware if Safety Kleen or University Field Operations performed the separator cleanout in conjunction with the removal of other on-site waste products. A sheen was observed on the surface of the contents within the separator during the site visit and it appeared that the separator was in need of cleanout. The oil/water separator does not appear to represent a REC to the site at this time. However, Terracon recommends that a current cleanout be conducted to limit the potential of a release of petroleum products on the site.

Interior Floor Drains Interior floor drains were observed in the bathroom of the FRB and a floor drain in the garage of the FRB associated with the oil/water separator and a sump referenced above.

There was no obvious indications of staining around the floor drains at the time of the site visit. The floor drains do not appear to represent a REC to the site at this time.

Electrical Transformers/POBs Pad or Pole-Mounted Transformers and/or Capacitors Fourteen (14) pole-mounted transformers and one pad-mounted transformer were observed on the subject site. The transformers are owned and serviced by Boone Electric Cooperative. Transformers contain mineral oil, which may contain minor amounts of PCB and could be considered "PCB contaminated" (PCB content 50 to 500 ppm).

Boone Electric Cooperative maintains responsibility for the transformers, and if the transformers were "PCB contaminated," the utility company is not required to replace the transformer fluids until a release is identified. However,. no evidence of current or prior releases was observed in the vicinity of the electrical equipment during the site visit.

18

Discovery Ridge Terracon Project No. 09067718 May 31, 2006 Evidence of Releases or Potential Releases Stained Pavement or Similar Surface Minor staining of concrete flooring was observed in the civil engineering building around the waste oil drums and 5-gallon buckets. The concrete surface in this area was not cracked at the time of the site visit. The minor staining does not appear to represent a REC to the site at this time based upon small area of staining and apparent good condition of the concrete floor surface.

Construction/Demolition Debris and/or Dumped Fill Dirt Mr. Poehlmann stated that a historic lagoon on the site was filled in the past prior to regulatory requirements for formal closure sequencing. The lagoon was reportedly used to hold hog waste associated with an off-site study on swine waste and leachfields conducted in the past. Mr. Poehlmann was not aware of the exact location of the former lagoon on the site or the type of material used for backfill but he assumed that the lagoon was backfilled with its earthen berm.

Other Notable Site Features Surface Water Bodies A lake was observed on the northeastern portion and a lagoon was observed on the north-central portion of the site during the site visit. Sheens or evidence of a release were not observed on the water surface of the lagoon and lake during the site visit. According to Mr.

Poehlmann, the lagoon is in the process of closure and has a MDNR operating permit and the Missouri Department of Conservation manages the lake.

Wells According to Mr. Poehlmann, a water well is located on the site. A water well search of MDNR Geological Survey and Resource Assessment Division database information for the area of the site did not specifically identify the well and the location of the well on the site was not determined at the time of issuance of this report. The water well does not appear to represent a REC to the site at this time. However, Terracon recommends that the water well be properly abandoned according to MDNR regulations, if the well is encountered during future site development activities.

5.2.2 Interviews Conducted Associated with Site Reconnaissance The following individuals were interviewed regarding the presence or absence of the features listed in the table above. Unless otherwise noted herein, the interviewee was not aware of the listed features (identified in the Site Characteristics Table) at the site.

Obvious indications of RECs were not observed on the adjoining properties during the site reconnaissance.

7.0 ADDITIONAL SERVICES Per the agreed scope of services specified in the proposal, other additional services (e.g.

asbestos sampling, lead-based paint sampling, wetlands evaluation, lead in drinking water testing, radon testing, etc.) were not conducted.

8.0 FINDINGS, CONCLUSIONS, AND RECOMMENDATIONS 8.1 Findings and Conclusions This Phase 1 Environmental Site Assessment (ESA) of the above-referenced site was performed in accordance with our proposal dated April 6, 2006, and in general accordance with the consensus document known as ASTM E 1527-00, a guide for conducting ESAs.

Tim Bennett performed the site reconnaissance on April 18, 2006.

20

Discovery Ridge Terracon Project No. 09067718 May 31, 2006 The site is a 114-acre portion of the University of Missouri-South Farm which is proposed to be developed with a research park. The site is located at the approximate southwestern corner of the South Farm east of Lenoir Street and south of Sugar Grove Lane. Nine buildings associated with agricultural and engineering research and related equipment storage exist on the site. The site is generally located on the southeastern portion of Columbia, Boone County, Missouri.

A cursory summary of findings is provided below. It should be recognized that details were not included or fully developed in this section, and the report must be read in its entirety for a comprehensive understanding of the items contained herein.

• The site is located on an irregular-shaped plot of approximately 114 acres of land.

The site consists predominantly of farmland with nine buildings associated with agricultural research located on the northwestern portion of the site and a lake. The site is owned by the University of Missouri. According to Mr. John Poehlmann, Assistant Director of University of Missouri Agricultural Station and superintendent of the site, the site currently and historically has been used for agricultural research and teaching which included maize genetics crop research, swine nutrition, beef cattle management and grazing, agricultural equipment development, and cropping for grain, silage and uptake of nutrients from lagoon application.

• Observations made during Terracon's reconnaissance of the subject site included, but was not limited to 55-gallon drums, 5-gallon containers; an oil/water separator and sump associated with an indoor floor drain; aboveground storage tanks (ASTs) for water; a temporary underground storage tank (UST) for collection of wastewater; electrical transformers; a lake and a lagoon. Observations did not indicate recognized environmental conditions (RECs) associated with these features at the time of the site reconnaissance.

• Based on a review of historical information including, historical topographic maps, aerial photographs, and interviews, the subject site appears to have been developed by at least 1935 with apparent farmstead buildings. The development of the current-day buildings on the site appears to have begun between 1939 and 1948. The lake on the site appears to have been constructed between approximately 1948 and 1959 and the current-day lagoon constructed between 1974 and 1981. A review of registered water well information provided by the Missouri Department of Natural Resources (MDNR)-Geological Survey and Resource Assessment Division (GSRAD) did not identify a water well which is reportedly on the site at an unknown location. Development of the surrounding areas appears to have begun by at least 1935 with the development of current-day Highway 63 to the west and south and homes and buildings associated with surrounding farmland to the north, south, and 21

Discovery Ridge Terracon Project No. 09067718 May 31, 2006 west of the subject site. The development of the current-day Ed's Mobile Home Park and Sunset Mobile Home Park northwest of the site began between approximately 1948 and 1959.

• The current-day adjoining properties of the subject site consist of the following:

• Ed's Mobile Home Park and Sunset Mobile Home Park, farmland with University of Missouri storage buildings, and Sugar Grove Lane, to the north,

• Farmland and buildings associated with the University Beef Farm to the east,

• Lenoir Street, a residential house, Highway 63, Ponderosa Drive and farmland to the south, and

• Lenoir Street, Highway 63, Ponderosa Drive and the Phillips Farm to the west.

The adjoining properties do not appear to represent a REC to the subject site at this time.

• The regulatory database review identified no Environmental Protection Agency (EPA) facilities, and one (1) MDNR Underground Storage Tank (UST) facility within the specified search radii. Based on the regulatory status and topographic distance relative to the subject site, this facility does not appear to represent a REC to the subject site.

8.2 Recommendations Based on the Scope of Services for this assessment, Terracon did not identify conditions which, in our opinion, require additional investigation at this time. However;

• Terracon recommends a current cleanout of the oil/water separator in the garage of the USDA Field Research Building (FRB).

• Water wells may provide a direct migration pathway for contaminants to reach aquifers underlying a site, and therefore become a source of environmental concern. If the well on the site is encountered during the proposed site activities, Terracon recommends that the water well be properly abandoned according to MDNR regulations. Proper abandonment of water wells should be performed by a water well driller licensed with the State of Missouri, and requires notification to MDNR prior to abandonment.

• If the septic tank is to be encountered during future site development activities, it should be closed in accordance with Boone County regulations, if applicable.

Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on a relative (not an absolute) basis. Relative elevation information between sites of close proximity should be field verified. Sites with an elevation equal to or higher than the target property have been differentiated below from sites with an elevation lower than the target property.

Page numbers and map identification numbers refer to the EDR Radius Map report where detailed data on individual sites can be reviewed.

Sites listed in bold italics are in multiple databases.

Unmappable (orphan) sites are not considered in the foregoing analysis.

RCRAInfo replaces the data recording and reporting abilities of the Resource Conservation and Recovery Information System (RCRIS).

The database includes selective information on sites which generate, transport, store, treat and/or dispose of hazardous waste as defined by the Resource Conservation and Recovery Act (RCRA). Conditionally exempt small quantity generators (CESOGs) generate less than 100 kg of hazardous waste, or less than 1 kg of acutely hazardous waste per month. Small quantity generators (SQGs) generate between 100 kg and 1,000 kg of hazardous waste per month. Large quantity generators (LQGs) generate over 1,000 kilograms (kg) of hazardous waste, or over 1 kg of acutely hazardous waste per month. Transporters are individuals or entities that move hazardous waste from the generator off-site to a facility that can recycle, treat, store, or dispose of the waste. TSDFs treat, store, or dispose of the waste.

Targeted Brownfields Assessments-EPA's Targeted Brownfields Assessments (TBA) program is designed to help states, tribes, and municipalities--especially those without EPA Brownfields Assessment Demonstration Pilots--minimize the uncertainties of contamination often associated with brownfields. Under the TBA program, EPA provides funding and/or technical assistance for environmental assessments at brownfields sites throughout the country. Targeted Brownfields Assessments supplement and work with other efforts under EPA's Brownfields Initiative to promote cleanup and redevelopment of brownfields. Cooperative Agreement Recipients-States, political subdivisions, territories, and Indian tribes become Brownfields Cleanup Revolving Loan Fund (BCRLF) cooperative agreement recipients when they enter into BCRLF cooperative agreements with the U.S. EPA. EPA selects BCRLF cooperative agreement recipients based on a proposal and application process. BCRLF cooperative agreement recipients must use EPA funds provided through BCRLF cooperative agreement for specified brownfields-related cleanup activities.

05/08/2006 Data Release Frequency: Semi-Annually EDR PROPRIETARY RECORDS Manufactured Gas Plants: EDR Proprietary Manufactured Gas Plants The EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants) compiled by EDR's researchers. Manufactured gas sites were used in the United States from the 1800's to 1950's to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production, such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds are potentially hazardous to human health and the environment. The byproduct from this process was frequently disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil and groundwater contamination.

Depending on the geographic area covered by this report, the data provided in these specialty databases may or may not be complete. For example, the existence of wetlands information data in a specific report does not mean that all wetlands in the area covered by the report are included. Moreover, the absence of any reported wetlands information does not necessarily mean that wetlands do not exist in the area covered by the report.

Oil/Gas Pipelines: This data was obtained by EDR from the USGS in 1994. It is referred to by USGS as GeoData Digital Line Graphs from 1:100,000-Scale Maps. It was extracted from the transportation category including some oil, but primarily gas pipelines.

Electric Power Transmission Line Data Source: PennWell Corporation Telephone: (800) 823-6277 This map includes information copyrighted by PennWell Corporation. This information is provided on a best effort basis and PennWell Corporation does not guarantee its accuracy nor warrant its fitness for any particular purpose. Such information has been reprinted with the permission of PennWell.

Sensitive Receptors: There are individuals deemed sensitive receptors due to their fragile immune systems and special sensitivity to environmental discharges. These sensitive receptors typically include the elderly, the sick, and children. While the location of all sensitive receptors cannot be determined, EDR indicates those buildings and facilities - schools, daycares, hospitals, medical centers, and nursing homes - where individuals who are sensitive receptors are likely to be located.
