TO: Tom Butler tsst XF:- FROM: DATE: Interoffice Communication gygj. T. G. Grumbles October 14, 1986 MCC PRESENTATION VISTA Attached are copies of the overheads used for the MCC presentation. Below is a proposed paragraph for use in the minutes. A presentation was given to describe the current regulatory arena in the environmental area. The Environmental Protection Agency is promulgating new regulations at a "record" pace. These new regulations are broadening the definitions of hazardous materials, reducing allowable or permitted levels of pollutants emitted in water and air, and beginning to ban certain disposal options. These regulations will have significant capital and manpower expenditure impact on Vista in the next three to five years. Let me know if the above is sufficient. Thomas G.
