EXECUTIVE SUMMARY

Versar, Inc. (Versar) conducted a Phase I Environmental Site Assessment (ESA) of the Bricker Federal Office Building, 200 North High Street, Columbus, Franklin County, Ohio (subject property, Location 1: referenced as GSA inventory OH0208). The Phase I ESA was performed in conformance with the scope and limitations of American Society for Testing and Materials (ASTM) Standard Practice E1527-00 and additional U.S. General Services Administration (GSA) specifications.

The purpose of the Phase I ESA was to identify recognized environmental conditions (RECs) as defined by ASTM. ASTM defines a recognized environmental condition as “the presence or likely presence of any hazardous substances or petroleum products on the property under conditions that indicate an existing release, a past release, or a material threat of a release of any hazardous substances or petroleum products into structures on the property or into the ground, groundwater, or surface water of the property.”

The scope-of-work for the Phase I ESA included: (1) a physical inspection of the property and observations of the surrounding area; (2) interviews with persons knowledgeable of the subject property and surrounding areas; (3) review of prior property history; and (4) review of federal, state, and local regulatory files. No sampling activities were conducted as part of the Phase I ESA scope-of-work. Based on performance of the ASTM Scope-of-Work, this assessment revealed no RECs in connection with the subject property.

Although not a REC, one approximately 1,500-gallon fuel oil underground storage tank (UST) affiliated with the emergency generator is below grade within a concrete room on the east side of the building. The subject property is listed on the LUST database, but a “No Further Action” letter was issued. The current UST replaced a former UST in the 1990s. Property management indicated the UST is checked on a regular basis by Northern Management. The UST is not deemed to be a concern at this time provided it continues to meet applicable regulations.

Versar conducted an asbestos survey as a separate task. Although not a REC, asbestos was detected in mastic associated with vinyl floor tiles, thermal system insulation, sink coating, drywall systems, insulating cement, sealant, and roofing materials (assumed). See asbestos inspection report in Appendix N of this report. An Operations and Maintenance (O&M) Program should be implemented to manage identified/assumed ACMs. In the event of demolition and/or renovation activities, OSHA notification requirements should be followed, and ACMs should be removed by a licensed abatement contractor following applicable regulations.

This Executive Summary is presented for convenience only and should not be used in lieu of information presented in the entire report.

1.0 INTRODUCTION

1.1 Purpose

The purpose of the Phase I ESA is to identify and report recognized or potential environmental conditions related to historic and current activities at the Bricker Federal Office Building, 200 North High Street, Columbus, Franklin County, Ohio (subject property, Location 1: referenced as GSA inventory OH0208).

Versar prepared this Phase I ESA in general accordance with American Society for Testing and Materials (ASTM) Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process E 1527-00. Performing a Phase I ESA in general accordance with E 1527-00 may enable a user to satisfy one of the requirements to qualify for the Innocent Landowner Defense of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

ASTM defines a recognized environmental condition as “the presence or likely presence of any hazardous substances or petroleum products on the property under conditions that indicate an existing release, a past release, or a material threat of a release of any hazardous substances or petroleum products into structures on the property or into the ground, groundwater, or surface water of the property.”

Additional scope-of-work items addressed in this report in conformance with U.S. General Services Administration (GSA) protocol include the following:

• Presence of vegetation, wildlife, endangered species, conservation areas, wildlife refuges, park lands, and ecologically critical areas.

• Review of floodplain, historic sites, antennas or towers, and wetland information on or adjacent to the subject property.

• Determination of seismic zone for the subject property.

• Impacts or presence of asbestos, radon, noise, indoor firing range, PCBs, and roof-top utilities.

1.2 Statement of Limitations

The data presented and opinions expressed in the Phase I ESA are qualified as follows:

• Sub-grade areas (ie: utilities and electric vaults) outside of the building footprint were not accessible and could not be fully evaluated by Versar.

• Versar has performed services and prepared this report in accordance with applicable, accepted environmental consulting practices. We make no other warranties, either expressed or implied, as to the character and nature of such services and product.

C Versar derived data in this report primarily from observations, examination of records in the public domain, and interviews with individuals with information about the subject property. Except as otherwise stated in the report, Versar has not attempted to verify the accuracy or completeness of such information.

C The findings expressed by Versar in this report are limited to information obtained and should not be considered an opinion concerning compliance of any past or current owner or operator of the subject property with any federal and/or local law or regulation.

1.3 Methodology

The assessment encompassed a scope-of-work commonly applied to Phase I ESAs and was performed in accordance with GSA RFQ 80755, Scope-of-Work 3, dated April 20, 2005. The Phase I ESA was performed by Ms. Shaun Terranova, and included the following major components:

1. Reconnaissance of subject land and improvements, conducted on October 5, 2005, including:

• Interviews with available persons, owners, and occupants who had knowledge related to use and development of the subject property to identify concerns related to potential environmental impacts from current and previous land uses.

• Identification of materials, processes, and facilities currently present that may pose an environmental hazard.

• Review of chemical storage, handling, use, treatment, and disposal practices that may have resulted in adverse environmental conditions at the subject property.

• Review of topography of the subject property and surrounding sites, and identification of adjacent properties that pose a potential for adverse environmental impact to the subject property (i.e. neighboring gas stations with underground storage tanks, dry cleaners handling solvents, etc.). This included a visual assessment of adjacent sites performed from the subject property and public rights-of-way.

2. Review of an environmental regulatory report, which covered available databases to distances from the subject property as stipulated in ASTM Standard E 1527-00 to identify potential impact to the subject property from off-site sources.

3. Review of records (Sanborn maps, aerial photographs, topographic maps, chain-of-title, blueprints, etc.) to determine historic use of the subject property.

4. Review of NEPA Database report to determine endangered species, conservation areas, wildlife refuges, park lands, ecologically critical areas, floodplain, historic sites, antennas or towers, and wetland information on or adjacent to the subject property.

1.4 Reliance

This report is confidential and has been prepared for U.S. General Services Administration (Client). The Client, or any prospective purchaser or lender being part of this particular real estate transaction may rely upon information within this report. No additional party may use information contained in this report without obtaining written permission from Versar and the Client.

Versar’s duties and obligations extend to the Client and are not transferable to any other person, corporation, or organization without express written consent of the Client or Versar. Versar is not responsible for consequences arising from unauthorized third-party use of this report.

2.0 VISUAL INSPECTION FOR RECOGNIZED ENVIRONMENTAL CONDITIONS

Versar's property reconnaissance included a physical examination of the subject property and perimeter, as well as observations of the surrounding area. The reconnaissance consisted of visually determining potential release points of hazardous materials and petroleum products that might adversely affect the environment, and the presence of suspect contamination or environmentally sensitive areas (RECs). Versar was escorted by Mr. Philip Ramos, GSA representative, and interviewed Mr. Todd Reeder, GSA Property Manager, during the reconnaissance. Photographs taken during the subject property reconnaissance are in Appendix C. Field notes for the reconnaissance are in Appendix J.

2.1 General Property Observations

Versar observed no evidence of following on the subject property:

• septic systems, unusual or noxious odors C stressed vegetation, C roads or trails with no apparent outlet or purpose.

2.2 Hazardous Materials Storage, Use, and Disposal

2.2.1 Chemical Use and Storage

Versar observed de minimus quantities of chemicals at the subject property, as follows:

Basement Maintenance Storage

• Two flammable materials storage cabinets with miscellaneous chemicals

• Latex paint, lubricants, and adhesives on metal shelves

Janitorial Closets on Floors 1-7

• Janitorial grade “environmentally friendly” cleaners

Material Safety Data Sheets are kept in the Property Manager’s and maintenance offices, and are updated on a regular basis. The janitorial contractor provides annual safety training to employees.

Exterior maintenance and janitorial services are provided by D&A Building Services, pest control services by Terminix, and plant care by Plant People. Chemicals are kept in the building only by the janitorial contractor.

2.2.2 Solid and Hazardous Waste Storage and Disposal

Waste streams consist of general solid waste such as paper, cardboard, food wastes, and miscellaneous items. Trash is stored in a compactor on the dock on the east side of the building and is picked up three times a week by Republic.

2.2.3 Releases to Air

Versar observed no point sources of air emissions at the subject property other than from heating, ventilation, and air-conditioning. There are no air emission sources at the subject property currently regulated by federal, state, and/or local regulatory agencies.

The building is heated by natural gas-fired boilers on floor “Penthouse 1”. A cooling tower on the roof aids in air-conditioning the building. The cooling tower was updated within the last couple years. Chargon Laboratories supplies the chemicals for the boilers and cooling towers on a regular basis and performs monthly maintenance. Pre-filters on the HVAC are changed quarterly and bag filters on a yearly basis by Northern Management. No environmental concerns were noted.

2.2.4 Discharges to Water

Water discharge from the subject property consisted of sanitary discharges and storm water runoff from the building roof. Discharge water flows into storm drains within adjacent streets.

Versar did not observe water discharges from the subject property that would require pretreatment, a National Pollution Discharge Elimination System permit, or other federal/local permit or approval.

Versar observed sump and sewage pumps within a pit in the building basement. No odors were detected and no environmental concerns were noted.

2.3 Underground and Aboveground Storage Tanks

Versar’s reconnaissance included a visual inspection for indications of storage tanks, such as fill and vent pipes, fill ports, dispensing equipment, unexplained manholes, or concrete patching.

Although not a REC, one approximately 1,500-gallon fuel oil underground storage tank (UST) affiliated with the emergency generator is below grade within a concrete room on the east side of the building. The subject property is listed on the LUST database, but a “No Further Action” letter was issued. The current UST replaced a former UST in the 1990s. Property management indicated the UST is checked on a regular basis by Northern Management. The UST is not deemed to be a concern at this time provided it continues to meet applicable regulations.

Versar observed one, 500-gallon fuel oil AST associated with the emergency generator in an explosion proof room on the east side of the building. The emergency generator is connected to the elevator and emergency lights and checked on a monthly basis. The AST is partially on a concrete pad and partially on the concrete floor and is a self-contained system. The room is adequately ventilated with a double steel door. No staining, odors, or environmental concerns were noted. Mr. Reeder stated there have been no problems associated with the AST or UST.

Additionally, one, 10-gallon heating oil day tank is in the boiler room and one, 10-gallon heating oil day tank in the emergency generator room on floor Penthouse 1. The day tanks are associated with emergency systems and no environmental concerns were noted.

2.4 Electrical or PCB-Containing Equipment

2.4.1 Electrical Transformers

Versar inspected the subject property for electrical equipment that may contain polychlorinated biphenyls (PCBs), widely used in the electrical manufacturing industry until the mid-1970s, when banned from use because of unreasonable risk to human health and the environment.

Versar did not observe pole-mounted or pad-mounted transformers on the subject property. Mr.

Reeder indicated power to the building is from transformers within vaults beneath sidewalks, possibly on-site. It is unknown by Versar whether the transformer vaults are on-site or off-site.

An electrical switch room is in the basement of the building. As owner of the transformers, the utility would be responsible for cleanup of any leaks or spills of PCB oil.

2.4.2 Fluorescent Light Ballasts

Fluorescent lights are present throughout the building. Mr. Reeder indicated all ballasts and bulbs were replaced in 2005. No environmental concerns were noted.

2.4.3 Hydraulic Fluid

The building has one freight and three passenger elevators maintained by Fugi Tech (outside contractor) on a regular basis. Mr. Reeder was unsure whether the elevators were electric or hydraulic. The elevator cars were replaced between 1999 and 2002 and are inspected yearly by the State Fire Marshal. No environmental concerns were noted.

Trash is stored in a compactor on the east side of the building. No staining or environmental concerns were noted.

2.5 Asbestos-Containing Materials

Asbestos is the generic term used to describe a group of naturally occurring silicate minerals that can be separated into small, fine fibers. The most widely used types of asbestos are chrysotile and amosite. Other types include crocidolite, tremolite, anthophyllite, and actinolite. Exposure to these fibers has been linked to a number of health problems, including asbestosis, mesothelioma, and lung cancer. United States Environmental Protection Agency (U.S. EPA) regulations define “ACMs” as materials containing more than one percent (1%) asbestos.

Federal regulatory agencies have targeted friable asbestos as the primary source for release of and subsequent exposure to asbestos fibers. According to the U.S. EPA, friable ACM is material that can be crumbled, pulverized, or reduced to powder by hand pressure. Release of asbestos fibers during demolition or renovation of buildings containing friable ACMs is regulated under Various state and federal regulations.

The U.S. EPA banned the manufacture, installation, and processing of spray-on insulation and fireproofing in 1972. The application of spray-on material for fireproofing and insulation was banned by in 1973. The U.S. EPA banned molded and wet applied asbestos in 1975, and ACMs in mechanical system insulation (e.g., pipe and elbow pipe insulation and boiler insulation) were banned in 1976. ACMs in acoustical and decorative applications were banned by the U.S. EPA in 1978.

Versar conducted an asbestos survey as a separate task. Although not a REC, asbestos was detected in mastic associated with vinyl floor tiles, thermal system insulation, sink coating, drywall systems, insulating cement, sealant, and roofing materials (assumed). See asbestos inspection report under in Appendix N of this report.

If ACMs are encountered, OSHA notification requirements should be followed. An Operations and Maintenance Program should be implemented to manage identified/assumed ACMs. In the event of demolition and/or renovation activities, ACMs should be removed by a licensed abatement contractor following applicable regulations.

2.6 Radon

Radon is an invisible, odorless radioactive gas formed by decay of uranium in subsurface soil.

Radon gas migrates to the surface and dissipates to harmless concentrations outside. Based on such factors as building location and ventilation, it can accumulate inside buildings and closed spaces. The U.S. EPA recommends considering indoor remedial measures when radon concentration exceeds 4 picoCuries per liter (pCi/L) on an annual average basis.

The subject property is in Zone 1 (indoor average level >4 pCi/L), a geologic area of high potential for radon gas generation. The database report indicated the average result of screening measurements from federal testing in the vicinity was 3.3 pCi/L, below the EPA guideline recommendation for remedial measures. It is not likely radon concentration will exceed the EPA guideline on an annual average basis in areas of regular occupancy.

2.7 Indoor Firing Range

Based on the site reconnaissance, interviews, and review of historic documentation, a firing range does not currently exist (or did not historically exist) at the subject property.

2.8 Noise

The subject property is within the downtown area of the City of Columbus, Ohio. The subject property is exposed to noise levels typical of a metropolitan area based on transportation and pedestrian parameters. Versar did not note atypical noise levels during the reconnaissance.

2.9 Observations of Adjacent Sites

Versar viewed adjacent sites from the subject property and public rights-of-way. Versar observed no evidence of unusual or noxious odors, roadways with no apparent end, ASTs, or USTs on adjacent sites.

3.0 SUBJECT AND ADJACENT PROPERTIES

3.1 Location and Description

The subject property is located at 200 North High Street, Columbus, Franklin County, Ohio Figure 1 (Appendix A) shows the subject property on the United States Geological Survey (USGS) Southwest Columbus, Ohio 7.5-minute topographic map. A layout of the subject property is shown on Figure 2.

3.2 Current Property and Vicinity Uses

The subject property is currently utilized as an office building with multiple government agency offices. The Department of Development indicated the subject property is zoned “mixed use.”

One closed walkway extends over High Street and connects the subject property to the William Green Building; and one closed walkway extends over Hickory Street to the 246 High Street office building. Two stairwells extend to most floors and an individual stairwell serves the basement. The building has one freight and three passenger elevators. Remaining portions of the subject property include Pearl Street (gated) and Hickory Street (walkway). A dock is on the east side of the building.

Mr. Todd Reeder indicated the federal government was given a land deed by the City of Columbus to the subject property, including Pearl Street and Hickory Street, following the September 11, 2001 terrorist attack for security measures. He further stated the City of Columbus maintains sewer lines and utility corridors. A Plat of Survey was not provided for review.

Utilities provided to the subject property include electricity, natural gas, water, and sanitary sewer. Electricity is provided by American Electric Power. Natural gas is provided by Columbia Gas. Public water and sanitary sewer services are provided by the City of Columbus.

4.0 HISTORICAL USE

4.1 Historical Sanborn Maps and Aerial Photographs

Versar reviewed historical aerial photographs and Sanborn Fire Insurance Maps to determine past land use of the subject property and surrounding area. The following historical data was reviewed:

• Historical aerial photographs for the years 1938, 1957, 1964, 1971, 1988, and 1994 obtained from EDR. Copies of the aerial photographs are in Appendix D.

• Historical Sanborn maps for the years 1887, 1891, 1901, 1921, 1951, and 1971. The

Sanborn Map Report is in Appendix E.

1887 Sanborn Map The 1887 Sanborn map indicated the subject property was developed with a drug store, offices, undeveloped areas, livery, and other commercial properties. North Pearl Street was adjacent east, East Spring Street was adjacent south, North High Street adjacent west, and East Hickory Street adjacent north of the subject property. The surrounding area was mixed use.

1891 Sanborn Map The 1891 Sanborn map indicated development of the subject property had changed. The Bijou Theater was present in the center of the subject property. Gook’s Hotel was across Hickory Street north of the subject property. There was increased and changing development to the surrounding area.

1901 Sanborn Map The 1901 Sanborn map indicated change in development on the subject property. W.R. Breyers & Company Shoe Factory was on the east side of the subject property, commercial properties along High and Spring Streets were referred as “Hughes Block” and the Bijou Theater appeared to expand. There was increased development to the surrounding area.

1921 Sanborn Map The 1921 Sanborn map indicated change in development on the subject property. An auto shop was on the northeast portion and horse collar factory on the east portion of the subject property.

Tanks which could have been associated with the auto shop would have excavated and removed during construction of the building basement/foundation and should not impact the subject property. There was a change in development to the surrounding area.

1938 Aerial Photograph The 1938 aerial photograph indicated the subject property and surrounding area were developed.

The scale of the photograph is too small to depict details.

1951 Sanborn Map, 1957 Aerial Photograph, and 1964 Aerial Photograph The 1951 Sanborn map indicated Moby’s Inc. Department Store, two restaurants, office, bakery, parking, and commercial properties occupied the subject property. Development to the surrounding area changed. The 1957 and 1964 aerial photographs indicated the subject property and surrounding area were developed. The scale of the photographs is too small to depict details.

1971 Sanborn Map and Aerial Photograph The 1971 Sanborn map indicated the subject property had changed. Commercial properties, two restaurants, private garage, and parking lots occupied the subject property. The 1971 aerial photograph indicated the subject property and surrounding area were developed. The scale of the photograph is too small to depict details.

1980 and 1994 Aerial Photographs The 1980 and 1994 aerial photographs indicated the subject property and surrounding area were developed. The scale of the photographs is too small to depict details.

4.2 Historic Site Discussion

The National Environmental Policy Act of 1969 (NEPA) requires that Federal agencies include in real property decision-making processes appropriate and careful consideration of all environmental effects and actions, analyze alternatives for public understanding and scrutiny, avoid or minimize adverse effects of proposed actions, and restore and enhance environmental quality as much as possible. Versar retained EDR to provide a NEPA database report to determine if nearby historic buildings, sites, or districts might affect redevelopment of the subject property.

The NEPA database report is in Appendix F and indicated the following historic sites within 0.25-mile of the subject property:

Historic Sites: Columbia Building Columbus Savings and Trust Building East Gay Street Commercial Historic District Central Building of the Columbus YMCA Long and Third Street Commercial Building Columbus Transfer Company Warehouse Rankin Building Welsbach Building

4.3 Results of On-Site Interview

Mr. Todd Reeder, GSA Property Manager, indicated the building was constructed circa 1975 and open for occupancy in 1976. Mr. Reeder further stated the original UST for the building was replaced and upgraded in the 1990s. There have been no problems with the AST or UST.

5.0 STANDARD DATABASE SEARCH

5.1 Federal Regulatory Review

Versar retained EDR to provide a database search of environmental records (database report) maintained by the federal government. The scope of the database search was in accordance with ASTM Standard E 1527-00. A copy of the database report is in Appendix H. Specific federal databases searched are listed below:

Database Type of Records Radius Searched

NPL National Priorities List (Superfund) Sites 1-mile Proposed NPL Proposed NPL Sites 1-mile Delisted NPL Delisted NPL Sites 1 mile ROD Superfund Records of Decision 1 mile NPL Liens Federal Superfund Liens Property CERCLIS Potential Hazardous Waste (CERCLA) Sites 0.5-mile CERC-NFRAP Investigated Hazardous Waste Sites 0.25-mile with No Further Remedial Action Planned CONSENT CERCLA Consent Decrees 1 mile RCRIS-TSD RCRA Treatment, Storage, and Disposal Facility 0.5-mile RCRIS-LQG RCRA Large Quantity Generator 0.25-mile RCRIS-SQG RCRA Small Quantity Generator 0.25-mile CORRACTS RCRA Corrective Action Sites 1-mile RAATS RCRA Violators Property ERNS Emergency Response Notification Sites Property FINDS Facility Index System Property HMIRS Hazardous Materials Spills Incidents Property MLTS Material Licensing Tracking System Property

MINES Mines Master Index File 0.25-mile PADS PCB Activity Database System Property TRIS Toxic Release Inventory System Property TSCA Toxic Substances Control Act Property FTTS Federal Insecticide, Fungicide, and Rodenticide Property Act and TSCA Tracking System

Property = The search of the specified federal database was limited to the subject property address.

The Facility Index System (FINDS) database contains both facility information and “pointers” to other sources that contain more detail. The database report indicated the subject property is on the OHIO CORE database, but information was not available.

The Resource Conservation and Recovery Information System (RCRIS) database includes selected information on sites that generate, store, treat, and dispose of hazardous waste.

One RCRA-LQG (large quantity generator) sites and thirteen RCRA-SQG (small quantity generator) sites were identified within 0.25-mile of the subject property. Stilson Laboratories, Inc. (170 North High Street), Central Oil Asphalt Corporation (8 East Long Street), and Goodyear Tire Company (124 Spring Street) had violations between 1991 and 1993, but compliance was achieved in all occasions.

The database report identified sites that could not be mapped. Based on Versar’s area reconnaissance, given address information, and review of a local street map, the sites are not located adjacent to the subject property.

The above sites have no listed violations or have corrected violations. The database does not indicate releases of hazardous wastes, and utility corridors separate the subject property from migratory pathways. Based on this information, the above sites are unlikely to pose an environmental concern to the subject property.

5.2 State Regulatory Review

Versar retained EDR to provide a database search of environmental records maintained by the State of Ohio (Appendix H). The scope of the database search is in accordance with ASTM Standard E 1527-00. Specific Ohio databases searched are listed below:

Database Type of Record Search Radius

State Haz. Waste Sites OEPA State Oversight List 1-mile State Landfill OEPA Solid Waste Landfills 0.5-mile DERR Division of Emergency & Remedial Response 1-mile LUST Leaking Underground Storage Tank Sites 0.5-mile UST Registered Underground Storage Tank Sites 0.25-mile UNREG TANKS Ohio Leaking UST File 0.5-mile HIST LF Old Solid Waste Landfill 0.5-mile CDL Clandestine Drug Lab Locations Property USD Urban Setting Designation Sites 0.5-mile VCP Voluntary Clean-up Program Sites 0.5-mile MSL Master Sites List 1-mile

The subject property is listed on the database, but a “No Further Action” letter was issued. The subject property is also listed on the Ohio Spills database for a release of black material on March 23, 1998.

Versar submitted a Freedom of Information Act (FOIA) request to various Departments of the Ohio Environmental Protection Agency (OEPA) regarding the subject property and other sites which could be a potential environmental concern. OEPA – Division of Emergency and Remedial Response indicated there was a spill of unknown black powder on September 23, 1998. Documentation indicated the Federal Bureau of Investigation handled the situation and further information was not available. OEPA – Division of Air Pollution Control had information regarding the type of boiler utilized at the subject property. No environmental concerns were noted. Remaining agencies indicated no records for the subject property. Copies of FOIA requests and responses are in Appendix I.

Thirty-two LUST sites were identified within 0.5-mile and four registered UST sites were identified within 0.25-mile from the subject property. One LUST site, Columbus Southern Power Company (215 North Front Street) was identified within 0.125 mile and nine sites were identified between 0.125 and 0.25-mile of the subject property. Remaining LUST sites were identified between 0.25 and 0.5-mile from the subject property. The Columbus City Police Department (release Janaury 30, 1991) had no response to the NCR letter and Republic Parking Garage (July 31, 1989) had the Initial Corrective Completion Report. The remaining LUST incidents within 0.25-mile have “No Further Action” letters status.

The DERR database is an index of sites for which OEPA maintains files. It includes sites with known or suspected contamination, but a site’s inclusion in the database does not mean that it is now or has ever been contaminated. Nine DERR sites were identified within one mile of the subject property.

OH MSL is no longer maintained by the OEPA, but it was a list of sites with known or suspected contamination. Inclusion on the list does not indicate a site or may be contaminated. Three OH MSL sites were within one mile of the subject property and one Voluntary Action Program (VCP) site was within 0.5-mile of the subject property.

The database report identified sites whose locations could not be mapped. Based on Versar’s area reconnaissance, given address information, and review of a local street map, the sites are not located adjacent to the subject property.

Based on “No Further Action” status, proximity, and presumed groundwater flow direction, the above sites are unlikely to pose an environmental concern to the subject property.

5.3 Local Regulatory Review

Versar submitted a FOIA request to the Columbus Health Department regarding USTs, soil or groundwater contamination, or hazardous spills on adjacent properties which could be a potential environmental concern. The Columbus Health Department indicated an unknown substance was delivered to an office at the subject property. The material was collected, taken to the laboratory, and tested. The substance was found to be pyrodex and there was no cause for action. The case was closed. A copy of the FOIA request and response is in Appendix I.

5.4 Environmental Lien Status

The database report (Appendix H), indicated the subject property did not appear on the NPL, NPL Liens, Delisted NPL, or Comprehensive Environmental Resource, Compensation, and Liability Information System (CERCLIS) databases. Based on review of acquired data, there is no evidence of environmental liens against the subject property.

6.0 GEOLOGY, TOPOGRAPHY, AND GROUNDWATER

The USGS Southwest Columbus, Ohio topographic map indicated the subject property has an approximate elevation of 742 feet above mean sea level and surface topography of the area slopes gently towards the Scioto River.

Beneath the subject property lies approximately 200 feet of Wisconsinan Pleistocene Age river-deposited, water-bearing sand and gravel. These unconsolidated deposits rest unconformably over carbonate bedrock of Silurian to Ordovician Age.

Groundwater is found in the unconsolidated deposits and underlying bedrock. The database report indicated no wells on the subject property. Wells identified in the surrounding area are shown on the physical setting source map in the database report. Based on regional topography, groundwater flow direction in the immediate vicinity is south-southwest to the Scioto River.

6.1 Surface Waters, Flood Plains, and Wetlands

The database report indicated there are no surface water bodies on the subject property and the closest surface water is the Scioto River, between 0.25 and 0.5-mile west of the subject property.

Storm water from the subject property discharges into storm sewers under adjacent streets maintained by the City of Columbus.

The subject property and surrounding area is not within a 100 or 500-year mapped flood zone.

The subject property lies within Zone “X” (area determined to be outside the 0.2% annual chance floodplain) delineated on the Federal Emergency Management Agency, National Flood Insurance Rate Map, Community Panel Number, 39049C0243H, effective date March 16, 2004.

A copy of the map is in Appendix G.

Wetlands are jointly defined by the U.S. EPA and the U.S. Army Corps of Engineers as “those areas that are inundated or saturated by surface or ground water for a duration and frequency sufficient to support and under normal circumstances do support a prevalence of vegetation adapted for life in saturated soil conditions.”

Versar reviewed the United States Department of the Interior National Wetlands Inventory Map of the area which indicated no designated wetlands on the subject property or in the surrounding area. The closet wetlands are along the Scioto River, between 0.25 and 0.5-mile west of the subject property. A copy of the map is in Appendix K.

6.2 Seismic Zone

A Seismic Risk Map of the United States dated 1995 indicated the subject property is in Zone1.

The map key indicated Zone 1 areas may have minor damage from a remote earthquake. A copy of the Seismic Risk Map is in Appendix K.

6.3 Vegetation, Wildlife, Power Lines, and Towers

The NEPA report indicated the following within 0.125-mile of the subject property:

Endangered Species: Clubshell and Northern Riffleshell Clams, Scioto Madtom (fish), and

Indiana Bat

Vegetation, Conservation Areas, Wildlife Refuges, Parklands, and Ecologically Critical Areas: None at subject property or adjacent sites

Power Lines: None at subject property or adjacent sites

FCC & FAA

Towers: Three sites within the search radius, but specific addresses were not listed.

7.0 ENVIRONMENTAL ANALYSIS SUMMARY

Pursuant to the GSA Scope of work, Versar developed the following table to address areas of concern outside the scope of ASTM 1527-00.

AREA OF CONCERN IMPACT

Subsurface Conditions Soils No Probable Impact Minerals No Probable Impact Groundwater No Probable Impact Hydrology Water Drainage/Storm water No Probable Impact Water Quality No Probable Impact Landforms Topography No Probable Impact 100-Yr Floodplain No Probable Impact 500-Yr Floodplain No Probable Impact Coastal Zone Area Not Applicable Wetlands No Probable Impact Wildlife/Plants Vegetation No Probable Impact Animal Wildlife No Probable Impact

Endangered Species No Probable Impact Conservation Areas No Probable Impact Wildlife Refuges No Probable Impact Parklands No Probable Impact Ecologically Critical Areas No Probable Impact Land Use Existing Zoning No Probable Impact Natural Hazards Seismic No Probable Impact Cultural Resources Historic Sites/Districts No Probable Impact Historic Buildings No Probable Impact Utilities Waste Disposal No Probable Impact Sewers No Probable Impact Environmental Concerns

Underground Storage Tanks Potential for Impact Site "Contamination" No Probable Impact Hazardous Materials Storage No Probable Impact

Asbestos Present or Suspected

Certain Impact - Asbestos-containing materials were identified at the subject property (See asbestos report in Appendix N)

AREA OF CONCERN IMPACT

Radon No Probable Impact

PCBs Potential for Impact – It is not known by Versar whether the transformer vaults are on-site or off-site.

Noise No Probable Impact Air Quality No Probable Impact Indoor Firing Range Not Applicable Roof-top Utility Present No Probable Impact

Details concerning table conclusions follow:

1) Subsurface Conditions: Soils, minerals, and groundwater have no probable impact on the subject property, based on parameters discussed in Section 6.0.

2) Hydrology: Water Drainage/storm water, and water quality have no probable impact on the subject property, based on city-provided utilities, and potable water provided by a U.S. EPA-compliant public works.

3) Landforms: Based on location within the developed downtown district and location relative to waterways, topography, floodplain, or wetlands have no probable impact on the subject property.

4) Wildlife: Based on location within the developed downtown district, vegetation is confined to surficial imported plants and wildlife is typically confined to pigeons and other birds. Based on location within the developed downtown district, parklands, wildlife refuges, and conservation areas have no probable impact on the subject property. The Indiana bat is listed on endangered species, but is not likely to set up nesting in a high rise building. Other endangered species listed in the area are aquatic and cannot impact subject property development.

5) Land Use: Based on location within the developed downtown district, zoning has no probable impact on the subject property.

6) Natural Hazards: A Seismic Risk Map of the United States dated 1995 indicated the subject property is in Zone 1. The map key indicated Zone 1 areas may have minor damage from a remote earthquake.

7) Cultural Resources: As listed in Section 4.2, historic structures have no probable impact on the subject property.

8) Utilities: Sewers are provided by the City of Columbus; and hauling away of non-hazardous waste has no probable impact on the subject property.

9) Environmental Concerns: One UST is on-site, but does not pose a threat at this time.

Hazardous material storage was generally de minimus or in order. ACM was identified and is addressed in a separate report. Radon, noise, and air quality are not deemed to be significant.

Fluorescent light ballasts were changed in 2005. It is unknown whether transformer vaults are on-site or off-site. Transformer vaults were inaccessible and not inspected by Versar. With the exception of ACM and possibly PCBs, the above listed concerns have no probable impact on the subject property.

8.0 CONCLUSIONS AND RECOMMENDATIONS

Versar conducted a Phase I ESA of at the Bricker Federal Office Building, 200 North High Street, Columbus, Franklin County, Ohio (subject property, Location 1: referenced as GSA inventory OH0208). The Phase I ESA was performed in conformance with the scope and limitations of ASTM Standard Practice E1527-00 and conformed to additional GSA specifications.

Based on performance of the ASTM Scope-of-Work, this assessment revealed no RECs in connection with the subject property.

Although not a REC, one approximately 1,500-gallon fuel oil underground storage tank (UST) affiliated with the emergency generator is below grade within a concrete room on the east side of the building. The subject property is listed on the LUST database, but a “No Further Action” letter was issued. The current UST replaced a former UST in the 1990s. Property management indicated the UST is checked on a regular basis by Northern Management. The UST is not deemed to be a concern at this time provided it continues to meet applicable regulations.

Versar conducted an asbestos survey as a separate task. Although not a REC, asbestos was detected in mastic associated with vinyl floor tiles, thermal system insulation, sink coating, drywall systems, insulating cement, sealant, and roofing materials (assumed). See asbestos inspection report in Appendix N of this report. An Operations and Maintenance (O&M) Program should be implemented to manage identified/assumed ACMs. In the event of demolition and/or renovation activities, OSHA notification requirements should be followed, and ACMs should be removed by a licensed abatement contractor following applicable regulations.
