TO: Distribution 1 FROM: DATE: Interoffice Communication SUBJ: T. G. Grumbles March 21, 1988 ANALYTICAL WORK FOR REGULATORY REQUIREMENTS VISTA Based on a review of the list Jim Yates prepared, it is clear that benzene and the PNA's are the chemicals with the potential to appear most often in our products. Therefore, initial efforts should be prioritized towards the analytical work for those two chemicals. From a Proposition 65 standpoint warnings are required now for benzene and will be required beginning in July for the PNA's. If analytical method development is required for the PNA analysis, this should be high priority. Second in priority, based on regulatory deadlines and product volume in commerce, would be EtO and dioxane. We already know a lot about these levels and additional work may only include data gathering, reviewing sampling frequency, and determining if current sampling frequency allows us to generate representative data. Third in priority would be the various chlorinated compounds on the Prop 65 list. These are BCME, CCL4, chloroform, epichlorohydrin, PCB's and vinyl chloride. These chemicals have the potential to be present in less volume for commercial purposes, but the warnings will be required in October of this year, except for BCME which is required now. The remaining analytical needs are for DEHP, nickel catalyst fines, lead acetate and arsenic. Arsenic warnings are required now. Attached is a suggested "project*' organization based on the priorities described. Also, I've listed several general issues that should be considered. It should be noted that some PCB analysis and benzene in LAB work has been done in response to other regulations in the last two years. In several cases, collection of existing data will be our first step. Please review the enclosed then we'll schedule a conference call to discuss details of the project. \ cr^~------------ T, G.
