Lochhead Execmive Director Michael R. Lang Division Dneclor I am writing this letter as a follow up to our phone conversation earlier today in which we discussed [he questions you raised in your letter to me dated June 4, 1997. The Division staff who have reviewed the revised permit package submitted by Powderhorn Coal Company look forward to resolution of these final questions and, approval of permit revision no. 2. The revised permit package is definitely a more useable product than its predecessor. We appreciate the effort that has gone into this revision. The questions below are referred to with by the same numbers used in previous correspondence. 80. The last correspondence from the Division regarding this question asked that PCC verify that Pond 5 had enough capacity to perform as designed if additional water from certain sumps were pumped into the pond, as proposed earlier. Afrer further review of the volume of the sump and pond, and in consideration of the fact that any transfer of water from the sump would be done at PCC's discretion (in regard to timing), we are satisfied [hat Pond 5 will be able [o perform as designed. No further response to this question is necessary. 96. Based on the fact that the culverts in question have been in place for a number of years, and that we are not aware of any performance problems caused by overflow due to excessive head at the culvert inlets, we are satisfied that the culverts in question should continue to function as designed. No further response to this question is necessary.
