Response

In A1ChemIE's negotiations with DOE relative to the lease of the CPDF facility and the procurement of the couipment from the Gas Centrifuge Enrichment Plant (GCEP) to disposal of classified and uranium contaminated equipment und materials has been discussed. Although no formal agreements have been reached it is our understanding that this equipment and materials will be stored or. buried by DOE at the ORGDP site or the Portsmouth Gaseous Diffusion Plant. This is noted in the attached Waste Management Plan.

Enviromental Report

1. REQUEST Provide information describing the engineering features that will be used to prevent or mitigate the release of hazardous chemicals to the environment.

RESPONSE: (a) Loading and unloading of the feed, product and tails cylinder will be performed within an enclosed loading dock. Accidental release due to cylinder rupture associated with the task w !. 1 1 be contained within this enclosed loadjng dock. If an accidental release should occur, the dock will be decontaminated prior to continued use. All naterials issued for decontamination will be collected and packaged for disposal in accordance with the enclosed Waste Management Plan.

I (b) Feed, product and tails cylinders will be stored within a dedicated nominally air tight storage room. The storage room will be equipped with halogon and hydrocarbon monitors with an audible alarm. If a cylinder should leak, it will be removed, repaired or the contents will be transferred to a new cylinder. The storage room will be ,

surveyed for contaminant deposition and decontaminated, if necessary.

(c) The gas centrifuge process is an inherently high vacuum system operating in the low torr to micron range and with a low process gas inventory.

. Also, any disruption of this vacuum results in automatic process shut down. At shut down, isolation valves J

will automatically close preventing process gas release. Gas within the system will then be evacuated into a withdrawal cylinder prior to restarting the process system. j

+c f

(d) No floor drains will be installed in the facility.

(e) All potentially hazardous chemicalst associated with facility operation will be collected, packaged and disposed of as outlined in the enclosed Waste Management Plan.

(f) Based upon the small amount of process gas in a centrifuge at any time and the fact that the process operates in . a high vacuum, it is highly unlikely that any release of process gas would be detected.

(g) All sanitary waste water will be processed by the Oliver Springs Waste Water Treatment Plant.

(h) The only planned releases to the environment directly associated with-

! the Oliver Springs operation are Xenon, Krypton and off-gas systems as discussed in 2. below. Those releases have been discussed with the TDHE Division of Air Quality and it is expected that they will approve their release to the atmosphere.

2. REQUEST Describe the off-gas systems for the process equipment, the ventilation system for the building, and the drain systems for process or hazardous chemical handling area.

RESPONSE a) There will be five process off-gas systems in the building as follows; ,

1) Purge Vacuum (PV), 2) Evacuation Vacuum (EV), 3) Feed Purge and Evacuation (FPE), 4) Tails Purge and Evacuation (TPE) and 5) Product Purge and Evacuation (PPE). Each of these systems will contain a cold trapping, a chemical trapping, or a mechanical trapping system to collect the process gas, other than Xenon or Krypton as noted above, that has entered any of the off-gas piping systems during both normal process operations and off-stream operations (cylinder change-out, etc).

These traps will be installed in the inlet to vacuum pumps or in the purge

d piping as appropriate. .All five of the process-off-gas systems will be connected to a single common vent above the roof.

(b) HVAC System The HVAC system has not yet been designed. However, it is planned to use the same criteria and the same basic design as was used for CPDF and the GCEP process buildings. In fact, service modules from GCEP will be .<;

rolocated to this facility. Hence, the cascade area HVAC supply ductwork, grilles, etc. will be the same .a s that used for GCEP with a nominal air flow of 250 CFM/ machine.

The building will be pressurized to 0.1" w.g. by a number of fan coil units utilizing natural gas as the heat source. The air will be recirculated or exhausted within the cascade as required to magntain a minimum area temperature of 75 F.

Should a fire occur, the operator will be alerted such that he can either shut down all exhaust fans or elect to use them for smoke removal.

The building control room will be air conditioned with a water cooled unit for personnel comfort and as required .

by the computer equipment. A seperate make-up air duct will be provided from the outside of the building. Storage areas, maintenance, emergency generator rooms, battery rooms, etc will .have dedicated HVAC systems as required - for the service.

All feed and withdrawal systems will be within the process area and require no further HVAC.

(c) No floor drains will be utilized at the Oliver Springs facility. All potentially hazardous chemica2s associated with facility operation will be collected, packaged and disposed of per the attached Waste Management Plan. '

i

3. REQUEST Describ2 the quantities and types of hazardous materials which would be released from the facility under normal and abnormal circumstances. Such  !

estimates should be supported by analysis and the enviromental impact of these releases should be stated.

RESPONSE: No identified hazardous materials will be -

released from the facility under normal or abnormal circumstances.

4.- REQUEST Based upon analysis discussed in Item 3, .

provide an environmental monitoring plan  ;

- indicating species to be sampled-and l analyzed and methods and frequencies for -

such monitoring.

RESPONSE: Environmental monitoring is not proposed for this facility, S. REQUEST Indicate the environmental regulations which are related to your facility and your plans for implementation.

, RESPOliSE: (a) Air Emissions: A1ChemIE is working very closely with the TDHE-Air Quality Division in emission evaluation. '

A1ChemIE plans to acquire a Tennessee '

Department of Health and Environment (TDHE) Air Quality Permit for the discharge of Xenon, Krypton.and process off-gas exhaust (see 2a above).

(b) Hazardous Waste: An evaluation of the projected hazardous waste stream

indicates that the facility will be classified as a small waste generator.

A1ChemIE will seek a determination from the TDHE- Division of Waste Management. l (c) Solid Waste: An evaluation of the  ;

projected solid waste stream indicates l that "special waste" will be generated. AlchemIE will seek a- 1 determination from the TDHE-Division of j Waste Management. Classified waste, both contaminated and uncontaminated, I will be transferred to DOE for storage or burial at ORGDP.

(d) Water Discharge Permit: All sanitary waste water will be directed into the Oliver Springs sanitary sewer system for treatment. The biodegradanble cooling tower waste water and blowdown as well as the machine cooling water l wastes will also be directed to the  !

Oliver Springs facility. A water l I

discharge permit is not expected to be required.
