I'll <br />email you shortly the LRP compaction data that Marcia found. <br />My TRA 19 comment on the 0.5 ml/I erred where it referred to 40 CFR. It should have referred to the limitation for total <br />settleable solids that is typically in CDPS discharge permits. I'll provide you a corrected comment shortly. <br />Tom <br />From: Welt, Kathy [mailto:KWelt@archcoal.com] <br />Sent: Tue 9/15/2009 7:11 AM <br />To: Kaldenbach, Tom <br />Cc: Talvitie, Marcia <br />Subject: RE: West Elk Mine (C-80-007), TR-119 PAR letter <br />OK - thanks.
