| Vapor Intrusion and Radon Qualifications and Experience |
| KEY PRINCIPALS |
| Thomas Hatton of Clean Vapor, LLC is recognized as a pioneer of soil depressurization technology. Tom has twenty years of work experience in design, and installation management of soil depressurization systems, both in residential and commercial buildings. |
| Qualifications & Experience |
| Over the past twenty two years our personnel have designed and installed over nine thousand radon and vapor intrusion mitigation systems. Although the main source of projects has been in the North East we have experience throughout the continental United States and Alaska. We have designed and installed systems for buildings constructed over diverse soil conditions. We have remediated buildings over clay soils, shale fractured rock, the compacted clay sands of Florida, the karst in the Midwest, Glacial Moraines of the North West and Alaska including Permafrost. Tom Hatton's project management portfolio ranges from residential properties, historic buildings controlled by the Department of the Interior, numerous multi-story steel concrete schools, commercial warehouses, strip malls, office buildings, Properties in NJ DEP remedial programs and US EPA Indoor Air Quality Head Quarters in Edison NJ. Mr. Hatton served as an advisor to the New Jersey Department of Community Affairs providing critical input and comment to the Uniform Construction Code Radon Hazard Sub-code, Adopted Amendments N.J.A.C. 5:23 –10.1, 10.3 and 10.4. As referenced in the Summary of Public Comments. Where local permitting is required we can facilitate permit acquisition and final construction approval certificates. A review of the projects listed below will indicate that we are strongly qualified and experienced in design and installation of soil depressurization systems. |

| GOSS INTERNATIONAL COMPANY, DOVER NEW HAMPSHIRE, NOVEMBER 2007-PRESENT |
The building has functioned as a manufacturer of large scale printing presses for since before the turn of the century has undergone 16 additions and is impacted by vapors from solvents and degreasing agents in the soil. The soil beneath the building was Permeability Mapped. Soils ranged from sandy bank run to highly compacted clay. Active soil depressurization systems designed to extract vapors. The solution required a diverse range of specified blowers and exact suction points locations to achieve intended pressure field extension results.

| BALDWIN SHOPPING CENTER, PARSIPPANY, NEW JERSEY, MARCH 2008 |
The building is a 1950’s era shopping center that is impacted by TCE from a Dry Cleaner. The underlying soils were low permeability indigenous silted clay. Contamination levels dictated that the floor slab be cut out and soils removed. While the soil was out lateral drilling was employed to for the purpose of developing a negative pressure fields beneath slabs of adjacent stores. A gravel bed and soil gas collection piping were installed in the former dry cleaner itself along with a new concrete floor. Active systems are currently depressurizing the soil beneath the former dry cleaner and adjacent stores.

| US PARK SERVICE 1989 |
Designed soil depressurization systems to correct indoor radon problems in historic buildings in Denali, Alaska. The systems were designed to deal specifically with the problems associated with permafrost and underground utilidors. Utilidors are a network of tunnels that serve as a conduit to provide utilities such as phone, electric and hot water steam heat from a central boiler. These systems were installed in August of 1987 and radon levels in all building were lowered below 4.0 pCi/l.

| FLORIDA HRS 1989 |
Provided consulting services to the Florida Office of Instructional Developments and the Department of Health and Rehabilitative Services to create a bank of test questions for the HRS Certification Exam for radon mitigators. Prior to performing radon remediation in the State of Florida, mitigators must pass this test. This bank of test questions provided the foundation for the US EPA Radon Contractor Proficiency Program exam as well as the NJ DEP Licensing exam for radon testers and mitigators.

| US EPA 1988 |
Participated in a federally funded project to evaluate different instruments designed to sample radon and permeability of soils. This project included thorough diagnostics of buildings along with a complete characterization of soils beneath the slab and immediately surrounding the building. Soils were evaluated in several states. We found that geological conditions in the state of Florida allow soil gas sampling procedures to present the most relevant data toward correcting indoor levels in buildings.

| US EPA 1987 |
Principal investigator in the 1987 Federal EPA Home Evaluation Program: performed diagnostic evaluations, radon and radon progeny analysis, charcoal canister and alpha track tests, designed and installed home specific mitigation systems based upon diagnostic information. The findings and recommendations were distributed by the EPA and state agencies to over fifty homeowners in five states. Research data from this project was the basis for the current US EPA Course Manual “Reducing Radon in Structures.”

| US EPA 1987 |
Diagnosed and prepared remedial plans for the radium contaminated residential homes in Montclair, New Jersey when elevated indoor radon was measured in homes built on radium-contaminated soil. The soils beneath and immediately surrounding the basement were mapped for radon concentration and soil permeability. From these variables, energy efficient systems were designed, installed, and radon concentrations remain below EPA standards for corrective action.

| US EPA 1985 |
Employed an air surveillance program for a US EPA Emergency Response program in Bowling Green, KY. Volatile and explosive vapors were emitted from ground fissures in the karsts system beneath the town. Emissions were mapped and qualified. Using rain, temperature and barometric variables, a mathematical model was developed to predict pollutant concentrations. This project marked the inception of soil depressurization technologies to remove soil based contaminates in and immediately surrounding buildings. At the January 2006 Air and Waste Management Vapor Intrusion conference Tom Hatton was cited as a contributing pioneer for his ground breaking work on this project.
