INTER-OFFICE MEMO TENNECO t l H EM I CALS, INC To Subject P, R. Scarlto At Burlington J. W. Poarch At Burlington EFA RECOVERY OF AR 901 - ESR 1006 Date July 21, 1977 L. M. Medeiros A. C. Siegel J. P. Sandstedt We have begun to develop a procedure for recovery of AR 901 which poten tially can satisfy EPA requirements. Unfortunately, only three tests were run when it became apparent that a sight glass would be needed in the recovery line to allow for visual detection of foam to prevent damage to the compressors. A work order was submitted last year to install a "bulls-eye" sight glass to allow our development work to proceed. This work order continues to get back-burner priority. In order to meet our EPA compliance schedules, this sight glass is needed. Can you expedite its installation? JWP/mz 'x'J. W. Poa rch COLORITE 018692
