TO: Interoffice Communication FROM: DATE: SUBJ: Jim Harris-Oklahoma City T. G. Grumbles August 28, 1989 TGG: JCL: MMG: AJO RF XF: _ STORAGE TIME FOR 3M 3500 OVM VINYL CHLORIDE SAMPLES I discussed the question of how long is acceptable with the LCVCM plant. They didn't develop quantitative data in the 1978-79 passive dosimetry studies, but they use a general guideline of 5 days maximum in a refrigerator. I think this is what most people would agree with based on the concerns for sample loss of volatile hydrocarbons. 3M or C-TEK may have a specific recommendation also. I would recommend we not pay standard testing for the recent analysis, assuming there isn't a contractual question. C5^ T. G. Grumbles ) dlj cc: H. D. Garrison, R. S. Battles-Okc VVV 000000211
