(2) If the installed asbestos insulation can be effectively sealed, do it versus replacement. (3) If a repair job on pipe, equipment, or a tank requires the removal of asbestos insulation in order to get at the work, then replace the asbestos insulation with approved, non-asbestos type insulation. Proper procedures must be followed during the removal, and proper disposal methods used for the asbestos insulation. (4) Maintenance Coordinators should fill out their WortOrder requests with all the above in mind. The Sistersville Plant is 30 years old, and being that old the piping and other equipment were originally insulated with asbestos. Much of the asbestos has been removed and safely disposed of in the landfill as repairs and replacements have occured. No insulation containing asbestos has been purchased since 1973, but some asbestos still remains. Concern has been expressed that plant personnel are continually exposed to airborne asbestos fibers from unsealed insulation and dust from the entire plant surface. Monitoring conducted in a number of Plant locations, including some having unsealed asbestos nearby, has shown below the detectable limit of the analytical method. Sampling downwind of asbestos removal operations shows the same non-detectab1e levels. We believe this is because the Insulator Mechanics carefully follow the procedures that have been developed to prevent contamination of the environment and themselves while removing asbestos. Maintenance Craftsmen (and Operators for that matter) may work along side of asbestos insulation. If they, or their ASE-iESTOS. GWW 2--6--86 sim UCC 022463 PAGE 1 of 2 Supervisors, feel that protective equipment is needed they can safely use throw-away coveralls and Comfo II Respirators. These are usually short duration jobs and certainly do not involve the potential of exposure as would an insulator whose job it is to remove and handle asbestos insulation. In many cases the risks created by the removal would far exceed any which would arise if the insulation were left in place effectively sealed. In conclusion, "The Plant does not intend to enter into a program for the wholesale removal of installed insulation for no other reason than that it contains asbestos."
