Long <br />Dwrsion Ovecmr <br />I received a copy of the proposed CDPS CO-0042161 renewal via e-mail from Darlene Casey. After <br />reviewing the proposed document, the Division has one clarification to make: <br />On page 2 of the Summary of Rationale, Facility Description, part B. Waste Water Treatment <br />Description; the sentence reads "Briefly, a single sedimentation pond treats underground mine drainage <br />and surface water runoff from the site." This is not accurate. More accurately, "Three treatment cells <br />aze used in combination to treat underground mine water drainage." The system is not designed nor <br />used to treat surface water nmoff. The permittee adds chemical flocculants and coagulants......" <br />The public comment period closes April 30, 2001. We hope this correction can be incorporated into the <br />final permit. The Division has no other comments regazding this permit at this time. Please call if you <br />have any questions. <br />Sincerely, <br />Jane Binns <br />Envi nmental Protection Specia{ist <br />C:/jhb/C82056/Dischazge permits/000042161memo.doc <br />
