Since it needs to be edited and combined <br />with your AVF findings for other areas at the same mine, I decided not to <br />have it typed. <br />You might want to combine the findings for the Colorado River alluvial <br />valley floor with your findings for the loadout area. Note that the <br />material damage finding for the Colorado River AVF assurr~s that the possible <br />effects of leachate from the refuse pile and mine water discharge upon <br />water quality are not significant. That assessment of possible effects <br />should be included in the PHC-CRIB analysis for this mine. <br />if you have any questions, or need any additional analysis, let me know. <br />/mt <br />Attachment <br />cc: Brian Munson <br />Jim Pendleton <br />
