RE: Excess Spoil Fill Inspections
Lorencito Canyon Mine, #C-96-084
Mr. Bentley:
The Division of Minerals and Geology has completed review of the 2"d and 3rd quarter
2002 excess spoil fill inspections for Fills 7, 8 and 9 at the Lorencito Canyon Mine. We
also reviewed responses received July 10, 2002 to our letter of June 12, 2002.
Excess spoil fills 7 and 9 must meet the requirements of Rule 4.09.1 and the design
standards approved in Exhibit 13 of the permit application. Excess spoil fill 8 is a valley
fill and must meet the requirements of Rules 4.09.1 and 4.09.2, in addition to design
requirements of Exhibit 13.
The Division previously asked LCC;
For all future reports submitted please add the following information;
• Please add to the certification the statement that Ronald Thompson, a
qualified professional specialist experienced in the construction of earth and
rockfill embankments, accomplished the inspection under the direction of
Charles McGlothlin.
• Please add to each report the date construction began on the fill
• Please note on the form that the inspection report is due within two weeks of
the inspection (for those inspections done to comply with Rule 4.09.1(11)(b)).
Please add to the report a section that addresses any instability, structural
weakness, or other hazardous conditions possibly noted during the
inspection.
Please ensure these four requests are completed on the 4th quarter 2002 and all future
excess spoil fill reports. Although most of these requested changes were noted in the
2"d quarter reports, the 3rd quarter reports did not include this information. In particular.
