Cattany <br />Division Director <br />Natural Resource Trustee <br />The Division of Minerals and Geology has completed review of the 15` quarter reports submitted <br />for sediment ponds, excess spoil fills, and discharge monitoring reports (DMR's) for the <br />Lorencito Canyon Mine. Please find the results of this review under the respective headings <br />below. <br />Sediment Ponds <br />The reports meet the requirements of Rule 4.05.9(17). Sediment levels are planned to be <br />determined in the 2"d quarter of this year. Completion of the sediment cleanout of Pond 9 <br />(north) was noted. Seeding and resetting of the sediment marker were not completed at the <br />time of the inspection. <br />Excess Spoil Fills <br />The reports reviewed for the three excess spoil fills meet the requirements of Rules 4.09.1(11). <br />Additional rock armoring of the downdrains was completed at Fill 7 during the quarter. Notation <br />concerning recertification of repaired areas at Fill 8 was noted. Completion of repairs to the <br />west downdrain at Fill 9 was also documented in the 15` quarter reporting. Minor reseeding of <br />the repaired areas is also necessary according to the report. <br />Discharge Monitoring Reports <br />No discharges occurred during the quarter, which is consistent with observations during DMG <br />field inspections. <br />We have no further questions or concerns at this time. If you have any questions, please call <br />me. <br />Sin ly, <br />~~. <br />K t Gorham <br />Environmental Protection Specialist II <br />t~ffice of Office of Colorado <br />Mined Land Reclamation Active and Inactive Mines GeologiF•al Survey <br />
