Scope VIM Yl. This procedure applies to atmospheric bleeders in material*service as noted below: cwloripe A.Atmospheric bleeders include all valved openings in piping and equipment for use as high point vents* low point drains* and/or equipment clearing connections in hazardous materials service noted in B below. This definition does not apply to atmospheric vents that are required by safety code or procedure (specific items Include - actuated vent valves between block valves in burner management systems* Injection pot openings* and the like). B. The following materials are considered hazardous for the purposes of this procedure: - Vinyl Chloride - Methanol - Poiivic - fuel Gas (Natural and Propane) - AMS (Emergency Rill Systems) - Adds -^Caustic arwLXheiiLWash - Phthallc Anhydride - Liquids 140F and Greater III. Procedure The following requirements must be met for all bleeders governed by this program. #* A. Bleeders not in use shall be plugged as noted below: >* - Blind flanges* plugs or caps shall be Installed vapor tight. Use of small diameter pipe extensions between r any bleeder and the plug shall be minimized. 7/08/86 Replaces 10/21/81 Section 1.366 Page 1 vab.oooioi9657 ABERDEEN CHEMICAL PLANT SAFETY AND HEALTH MANUAL HAZARDOUS SERVICE BLEEDERS III.

Harris March 28, 1991 VISTA The Bleeder Valve Survey of all the Vinyl Chloride lines was completed on March 27, 1991, as required by EPA Subpart V Regulations. Only one bleeder valve was found unplugged. The unplugged valve was found in the Old Module on the east end of the North Batch Hater Stripper. The appropriate persons have been informed and the valve is in the process of being plugged. A complete list of the bleeder valves surveyed is attached and a copy of the isometric drawings has been filed. If there-are any questions about the survey, please contact us. H.
