He explained the sampling results could lead to the state agency adopting **a different approach** bin the federal Environmental Preterites Agency In controlling vinyl chloride. "We want ta be aura that what EPA k doing will be adequate for the Texas situation,*' Tarr said. In hli talt, Tarr was critical of several aspects of the EPA's vlay) chlcrfde regu lations.
