Box 9583 Little Rock, AR 72209 Subject: Technical Proposal for Destruction of Stored Waste on the Vertac Site in Jacksonville, Arkansas Dear Mr. Mean: Vestinghouse Electric Corporation and HAZTECH, Inc. are pleased to submit the attached technical proposal for the on-site destruction of the stored waste on the Vertac site in Jacksonville, Arkansas. The proposal addresses three options for the handling and destruction of all materials stored above ground on the site. Vestinghouse will be the project manager for all work on site. The recommended option is to destroy the liquid or crystalline material using the Vestinghouse Pyroplasma process which is a thermal treatment technology. The system uses a plasma torch which produces Cemperatures between 5000°C and 15,000°C. The most important advantages of this process, relative to combustion processes, are very low emissions, very high destruction efficiencies, and low PIC (product of incomplete combustion) formation. In addition, this system is truly mobile. All of the process equipment is contained in one 48-foot trailer and can be sec up on site within one week. Ve believe that the Pyroplasaa destruction process is very well suited for your specific waste material. It is estimated that two Pyroplasma units will be required and that work will be completed in approximately one and one half years. The balance of the waste (solids material, sludges, and debris) will be incinerated using HAZTECH's transportable infrared incinerator, designed and manufactured by Shirco Infrared Systems, Inc. The system consists of a waste prepreparation system, feed metering system, infrared primary chamber, supplemental propane-fired secondary chamber, exhaust gas scrubber, data acquisition and control systems, and heating element power centers, all mounted on transportable trailers. All of these systems are described in detail in the attached proposal. 03107609 •3.1.11; As mentioned in my previous letter, the Pyroplasma system has been selected by the EPA for demonstration under the SITE (Superfund Innovative Technology Evaluation) program. This program provides for the on-site demonstration of innovative technologies where the EPA funds the sampling and analysis portion of a test and provides a written evaluation of the technology. Ve propose that Vestinghouse and the State of Arkansas jointly approach the EPA with the recommendation to perform the required trial burn for the Vertac site under the SITE program. The second option provides for the destruction of only the 2,4,5-T waste using the Pyroplasma system, and destroying the 2,4,-D waste and all of the solids with the HAZTECH incinerator. This option will apply the unique destruction advantages of Pyroplasma to the waste stream containing the higher levels of 2,3,7,8-TCDD, and reduces the overall program cost. The third option is to destroy all of the material on site using the HAZTECH incinerator. In all cases, Vestinghouse would be pleased to provide the services of our •— Corporate public relations personnel, at the State's request and at no (^J charge, to assist in any public hearings or meetings. It should be noted that this letter is a technical proposal with a Ln budgetary estimate. Since we were unable to determine the exact 0 quantities and conditions of the waste to be destroyed, we have made some Q assumptions based on the best available information and have provided cost estimates on a per unit basis. Based on our assumptions, the maximum price quoted is a firm price. Our assumptions are stated. Any contract would be subject to mutually acceptable terms and conditions. Ve regret that we were not notified of the original request for proposal; however, we sincerely appreciates the opportunity to provide a proposal for the remediation of this site. As you are aware, we also actively pursued this clean-up directly with Vertac. Ve look forward to more detailed discussions with you on this project. If you have any questions please contact Carrie Penman at 412-722-5709. Sincerely, ^ \^^,^. E. P.

JACKSONVILLE. ARKANSAS PROPOSAL TO THE ARKANSAS DEPARTMENT OF POLLUTION CONTROL AND ECOLOGY 1.0 INTRODUCTION 1.1 SUMMARY OF PROPOSED APPROACH m This proposal provides three options for the destruction of the waste material currently stored on the Vertac site in Jacksonville, Arkansas. A c0 broad base of equipment and experience in tfestinghouse and HAZTECH allows m us to offer options that enable ADPCE to respond to its particular ^ technical, regulatory, and political needs. 1.11 OPTION 1 Option 1 is the recommended option and provides for the destruction of the majority of the stored waste using the Vestinghouse Pyroplasma system. The liquid or crystalline material which can be made pumpable by heating to 150°F, would be destroyed in a plasma field with temperatures ranging from 5000°C to 15,000°C. This process is a pyrolytic process which means the waste is destroyed in the near absence of oxygen. The most important advantages of this process relative to combustion processes, are very low emissions, very high destruction efficiencies due to the high temperatures produced by the plasma torch, and low PIC (product of incomplete combustion) formation. Vestinghouse can set-up this system on site in approximately one week. The balance of the waste stored on site in solid fora (solids material, sludges, and debris) will be incinerated using the HA2TECH transportable incinerator designed and manufactured by Shirco Infrared Systems, Inc. This system consists of a waste preparation, feed metering system, -i- 03107612 infrared primary chamber, supplemental propane-fired secondary chamber, exhaust gas scrubber, data acquisition and control systems, and heating element power centers, all mounted on transportable trailers. 1.12 OPTION 2 The second option is to process only the 2,4,5-T waste material contained in approximately 3300 drums through the Pyroplasma system. This waste has much higher levels of 2,3,7,8-TCDD than the 2,4-D waste. Use of the Pyroplasma system on this waste would provide the unique advantages of the plasma torch, very high destruction efficiencies, low emissions, and low PIC formation, to the more highly contaminated waste stream and lower the '^t' overall waste destruction program costs. The balance of the waste, liquid -. and solid would be destroyed using HAZTECH's transportable incinerator. QQ in 1.13 OPTION 3 o 0 The third option is to destroy all of the waste material through the HA2TECH transportable incinerator. 1.2 SCHEDULE Vestinghouse and HAZTECH understand that the proposed schedule for this project is as follows: August 1987 Preliminary proposal assessment Presentation at public meeting in Jacksonville September 1987 Conduct final contract negotiations October 15, 1987 Contract placement December 1987 Mobilization January/February 1988 Demonstration testing of equipment March/April 1988 Begin operations -2- 03107613 Vestinghouse and HAZTECH will have all equipment available per the requested schedule. In addition, Vestinghouse and HAZTECH will make any required personnel available for public meetings/hearings, negotiations, permit applications, etc. to support the program and schedule. -3- 03107614 1.3 DESCRIPTION OF THE PYROFLA.SMA SYSTEM The Vestinghouse Plasma Systems mobile liquid waste destruction unit has been developed to destroy liquid organic waste materials by dissociating the organic contents into their atomic components. The Pyroplasma process is based upon the concept of pyrolyzing waste molecules using a thermal plasma field. The heart of the destruction system is a plasma torch. The system will use 700 to 850 kW of electric power across a colinear electrode assembly to produce an electric arc in a medium of dry low pressure air. The intense energy causes the air stream to be ionized, producing a thermal _ plasma with temperatures in the 5-15,000°C range, waste liquids are (\J injected directly into the plasma where the waste molecules are broken 00 into their atomic states in an oxygen deficient atmosphere. The atoms in o recombine according to chemical kinetics to produce hydrogen, carbon o monoxide, nitrogen, hydrogen chloride, paniculate carbon, and small amounts of carbon dioxide, ethylene and acetylene. The product gas is scrubbed with caustic soda to neutralize and remove acid gas (HC1) and to remove particulate carbon. The remaining gas is drawn off by an induction fan and flared. Each system will process 2-3 gallons per minute or approximately one ton per hour. r The entire system is process computer controlled. The computer updates temperature, pressure, flow, fluid reserve and other performance parameters, as well as provides continuous on-line monitoring of the process. The system is designed to fail safe even in the event of a total power failure. On board monitoring is installed in the control room to analyze the bulk gas constituents of the pre-flare gas. The complete unit is contained in one 48-foot trailer. In the three gallon per minute unit, the front of the mobile unit is the laboratory with the computerized monitoring system.
