Suite 1000 Irlington, Texas 76011 Re: Cesium 137 sealed sources for industrial pipe guages Dear Mr. Fisher; This refers to your NOTICE OF. VIOLATION dated March 16 1988.

I discussed the radioactive materials with Mr. Spitzberg on the telephone March 7, 1988 and assured him that General Discount Corporation had no intention of retaining the radioactive materials. I Contacted R/A Services, Inc of Odessa, Texas regarding the transfer of the materials to HANCO, Internati'onal The purchasers of the equipment. R/A Services representative was at the General Discount yardaby 9:30 7M March 8, 1988 to Transfer the sources. The sources were leak wipe tested, visually in-spected, locked, marked, surveyed and packaged for shipment to HANCO, International in Midland, Texas. The R/A Services repre-sentative had spoken with Mr. Spitzberg and Mr. Charles Cain regarding the sources on March 7 1988 prior to his arrival in Oklahoma City. I am forwarding copies of HANCO, International's Texas Radioactive Materials License along with that of R/A Services, Inc..HANCO, International received the sources on March 9, 1988 at there Midland, Texas Yard.

If there are any cuestions contact me or Mr. Hicks at R/A Services, Inc. (915) 563-4127 or Mr. Hanlon at HANCO, International (915) 563-5843.
