• • III IIIIIIIIIIIII III <br />Lid#$~/ <br />Getty Mining Company 23385 Routt County Road 33, Oak Creek, Colorado 80467 • (303) 879-4426 <br />August 3, 1984 <br />Mr. David Shelton <br />Colorado Mined Land Reclamation Division <br />423 Centennial Building <br />1313 Sherman Street <br />Denver, CO 80203 <br />RE: Information For Assessment Of NOV C-84-81 <br />Dear Mr. Shelton: <br />RECEIVE <br />AUG ~'7 1984 <br />PN Co oLDept of NataAallResourcesON <br />Enclosed please find material associated with the above referenced Notice <br />Of Violation. This material was discussed during the Assessment Conference held <br />Wednesday, August 1, 1984, of which you where the officer in charge. The <br />material includes information concerning the 10 year/24 hour precipitation event <br />at our surface monitoring site 99, on the unnamed tributary to Middle Creek as <br />well as internal documentation of environmental problems associated with the <br />Fish Creek Tipple dated January 24, 1984. <br />As can be seen from the calculations, Site 99 has a 10-year/24-hour peak <br />flow of 21.2 cfs. Also attached, are 1984 flow measurements for Site 99. The <br />flow measurements were taken approximately once a week. Between the April 28 <br />measurement and the May 8 measurement, there was a 0.25 cfs increase in the flow <br />rate. Sometime between May 8 and May 16 the flow rate at Site 99 was sufficient <br />to wash out the Cipoletti Weir. We therefore, are unable to determine the peak <br />flow rate arrd the date of the peak flow, but we do know that a flow rate <br />sufficient to wash out the Site 99 weir occured within seven days of May 16, <br />1984, the date on which Mr. Liddle conducted his inspection and issued NOV C-84- <br />81. <br />Those problems noted in the January 24 memo associated with culvert and <br />ditch maintenance activities were resolved in a matter of days, which is our <br />standard operating procedure. Those problems noted which required earth moving <br />activities were scheduled for completion during the summer months when the <br />condition of the earth materials is conducive for such activities. Those <br />activities have been initiated and are in the final stages of completion at this <br />time. <br />We submit for your consideration that the violation which occurred at Ditch <br />H-3 was unavoidable despite the exercise of reasonable care, based on the weekly <br />monitoring activities conducted arrd data gathered at Site 99, and therefore <br />propose no assessment for fault be made. We further submit that the January 24, <br />
