POWDERHORN <br />COAL COMPANY <br />May 26, 1993 <br />Ms. Janet H. Binns <br />Reclamation Specialist <br />Division of Minerals and Geology <br />1313 Sherman Street, Room 215 <br />Denver. CO 80202-2273 <br />RE: N.O.V. C-93-009, File No. C-81-041 <br />Dear Ms. Binns: <br />RE^EIVFD <br />MAY 2 7 1993 <br />Divisioe vi Mineras to uu~ipy;, <br />III IIIIIIIIIIIIIIII <br />999 <br />P.O. Boa 1430 <br />Pelisatle, Colorado 81528 <br />(303) 4647951 <br />Fax (303) 4547181 <br />Enclosed please find additional certifications dating back to 1981. <br />I am sorry that they were not copied when initially requested. Also <br />included are some copies of inspection reports that may affect the <br />subject violation. Please share this information with Dan Matthews. <br />The following inspection reports are enclosed: <br />March l0, 1981 - Reference made to rock underdrains being <br />completed. Note - prior to Feb. 82 regulations. <br />March 25, 1982 - Reference made to underdrains functioning <br />properly. <br />April 6, 1982 - Reference made to requiring quarterly <br />certifications. Note - no reference made to needing critical <br />phase certifications. <br />June 2, 1982 - Reference made to quarterly density testing. <br />I believe there was some question over the extent of <br />information needed in a quarterly certification. This report <br />indicates that density testing may have satisfied the requirements <br />at that time. <br />Considering this information it may be suitable to vacate the violation <br />or at least reduce the assessment to insignificant and unavoidable. <br />Please let me know if you have any further questions. <br />Sincer y, <br />~~-r~~~ <br />arry~ Reschke <br />Engin er <br />LMR:7P <br />Enclosures <br />cc: W.
