Dear Mr. Summers:
Your recent letter addressed to President Carter was forwarded to this office for response. Your letter concerned the recent grain elevator explosions.
We share your concern over the high financial burden borne by the grain industry and also the high loss of life incurred by the explosions. This agency is exploring all potential causes during our investigations of the accidents. We have also conferred with industry representatives and other knowledgeable groups, organizations and individuals in our efforts to find an effective and sensible solution to the problem.
The consensus at this time is that the collection of dust to prevent its release in the environment as required by the Environmental Protection Agency regulations is not a contributory cause of the explosions. We feel as you do that the handling of the dust after collection is suspect and is being evaluated as a possible contributing factor.
Your comments on our Grain Elevator Industry Hazard Alert are well taken. In promulgating the Alert, it was decided to alert the industry to all hazards involved in grain elevator operations which might also result in injury or loss of life, if not recognized and controlled.
Your letter also contained comments directed toward EPA and FGIS and we are forwarding a copy of your letter to these agencies for their consideration.
If I may be of any further assistance, please feel free to contact me.
