- 1) indi-vidual toxic gases, 2) explosive materials, and 3) materials which could ignite and yield high terr $ratures or generate other hazardous clouds ( flammable clouds) ch could affect plant A
safety.
The results of this effort'were that'the-hazard to the plant from shipment of-materials along Interstate 5 and the AT&SF railway-remains within acceptance criteria of Standard Review-Plan 2.2.3 and is therefore acceptable.

Document Control Desk -
As a result of our contacts with the AT&SF Railway Company, we have noted an increase in rail shipments of low pressure gas.
The number of shipments would need to increase by fifty parcent over that reported in the enclosed report before additional analysis is required, providing a large margin.
However, we plan to check on these shipments every year.
We will notify you if the number of shipments increases to the point that additional i
analysis is required prior to car next three year report.
The enclosed information complies with the requirements of Technical Specification 6.9.1.14 for both San Onofre Units 2 and 3 covering the three year period from Febreary 15, 1988 through February 15, 1991.
If you have any questions concerning the above information, please contact me.
Very truly yours
