Dear Mr. Crow:
This letter is in response to your recent telephone conversation inquiring about an expert fire safety review of the Kerr-McGee Coal Liquification Project at our Cimarron Facility. As you are aware, plant layout, design and construction for this project has be0un.
Included in these activities has been an evaluation of the fire protection provisions and recora11endations which were made by fire prctecticn consultants.
In addition, the Kerr-ficGee Nuclear Corporation's Cimarr.on Facility fire brigade has been extended to include a fire fighting
' crew expecially trained and managed by the coal group for emergency response involving the coal liquification operations.
A listing of the recommendations mcde by the fire protection consultants and the responses by Kerr-McGee is attached.
Sinceref?

(Insurors) have made an evaluation of the fire protection requirements of the Coal liquification project at our Cimarron Facility. Their recommendations and the project responses follows.
1.
The hydrogen compressor and the heat medium (Dow Therm) furnace should be separated by a clear space of 75 feet.
Reply:
Accomplished.
2.
Separation.of 50 feet should be maintained between Skid #1 (Utility) and the heat medium furnaces.
Reply:
Accomplished.
