I & E Bulletin 80-19

Dear Mr. Seyfrit:

We have checked our facility as requested in I & E Bulletin No. 80-19, and l

80-19 Revision 1.

We have none of the C.P. Clare Model #G2x-10ll mercury-wetted relays, described in the bulletin, in our plant orotective system.

Investigation and reporting required by Bulletin 80-19 required an i

estimated 5 man-hours.

We anticipate no further action on this bulletin.

Very truly yours, Oscar R. Lee 4
