<br />Memo - BMG Tailings uetoxification <br />BEI Study and Proposal <br />page 2 <br />consequences of their remedial action. In addition, we should condition our <br />approval upon BMG expeditiously completing a comprehensive reevaluation of the <br />chemical constituency of their modified tailings, including an evaluation of <br />the potential environmental impact of those tailings. I suspect that the <br />processing complications caused by the ore chemistry is resulting i~ an <br />unanticipated elevated 1?vel of a selection of metallic elements within the <br />tailings. The reclamation implications of this occurrence can be <br />significant. Finally, 1f the Division determines it to be appropriate, we <br />should require BMG to amend their existing reclamation plan for the tailings <br />disposal area. <br />I have also prepared a broader set of recommended abatement require ents for <br />imposition upon the NOPV issued March 31, 1992, which I have attach d for your <br />consideration. <br />attachment: <br />cc: Bruce Humphries <br />Mike Long <br />JP/JP <br />Doc.
