< (conoco) Interoffice Communication To Distribution From J. H. McCulley, Jr. Data May 7, 1982 Subject EPA VCM Standard Information Exchange Meeting A PVC plant VCM standard information exchange meeting will be held in Aberdeen on Friday, May H. The meeting agenda is attached. You will note that the agenda seems impossibly long. Hopefully a number of the items listed can be covered quickly. It is important to cover all the items under the relief discharge prevention heading. If necessary, some of the items may best be resolved in another meeting. Chief Process Engineer Chemicals Division Process Engineering Department pjc Enc CC: JF:CRM:PEM:RAF(2):SJV RAC:AWS:JPW:JH:JL:RJR File P--47-2 DTH 000070893 EPA VCM STANDARD INFORMATION EXCHANGE MEETING Objectives: 1. Discuss prevention of VCM relief discharges. 2. Discuss controls in other areas of the standard as time permits. 3. Share information. To this end I am designating a plant to take the lead in discussing their controls in each area. The other plant's representative would then discuss their differences, if any.
