The operation is to he as dcscribce in tl-c suma—lary ori rage 4 of ,PPendix r of. the F.rvironrnental doctinents. Che existing A-2 zone allows mining operations. The operation as descrkbed Ln the Reclamation Plan appears to meet the criteria of County Code Gha.ptei l3. and has been'submitted to the ­State Geologist as required. As the result ).f earlier hearings before the Planning Commission, a mitigated Negative !I Declaration is before you for adoption.. Mitigation measures are included and should be considered prior to a decision on the project. Three k.ey concerns of the neighboring property owners are traffic and road ,naintenance, the possibility of future blasting and the potential effects on the creek and their downstream springs, the domestic water supply for nost of the homes. kecess to the site is via Messilla Valley Road and Dry Creek Road. Dry Creek -oad is a privately maintained road and presently docs not meet any County tandards. Included as a mitigation measure is a condition to improve .eek Road ---"at such time as mining traffic warrants". Messilla la1 ey Road is publicly maintained and the Public Works Department has con- iitioned that any damage caused by mining operations be repaired. Che Logans have indicated that blasting will not be involved in the mitNg F 41-013-27 ..Page 3 Staff Findings April 8, 1982 oyer-ation. Therefore discussion and conditions relative to blasting are deleted. The potential effects on the creek and doA4nsticam springs have no` been studied in detail. Ken.Cole, Division of Mines and Gcology, recommends, in the letter, dated March.23, 1.982, that a "hydrologic report should: address' 'the effects of open -pit mining on the local graundwatbr system, ariticipated amounts of water whic:i will. have to be handled in.the pits, and expected groundwater flows through the reclaimed mincd'land." Contact has „con made with a Dr. .Jerold Behnke of Chico to explore the hydrology of the D -y Creek Road area and potential impacts, if any, posed by the mining operation.. Refer also to Condition #13. A performance bond has been recommended'as a method of assuring that recla= mation' will take place. 'In :the _event that the mining: operation did nbt prove successful or for some other reason' the Iogans were not able to initiate' and. complete reclamation' ..f tlic "-land, t•}ie perform4ne'e bond would allow the County to complete the work by hiring'someone .to do it. 'The Nevada County process of "performance assurance" is being reviewed. Tony Landis -Regional Water Quality Control'Boat&, Ken Cole=Department of Con- servation, Division'of Mines acid Geology .'and Gayland Taylor -Department of rand Game su'r'veyed the site along with 'th& Logan§, Frank Bennett. and Steve '1;.O.cter on March 12, 1982. As a result of the field trip, Mr. Logan tenta- tively agreed to a three-phase plan to expand the mining operation. Phase I would -:restrict. -him .toa•. maximum..output of 20 cubic yards per day, the limit- ation on his cur'r'ent' pe.rinit :from; the Department' of', Fi sh. and Game. Please I would double .the: output of min' ed.materia•1 to 40 cubic yards per day. Finally, Phase III would be for 80 cubic yards per day, the .figure originally re- quested.-for•the mining permit and in the draft reclamation plan. The phasing would allow for a more careful review of the mining operation by State agency representatives and County personnel. If through periodic monitoring a reasonable "track record" is established, then expansion from 20 cubic yards per day to 40 cubic yards per day could be considered by the Planning Commission. Basic questions to be answered for future expansion are the settling pond lo- cations, the amount of wastewater to be generated, how the wastewater would be -handled, how and where the tailings would be stockpiled for reclamation, and methods to assure that the water quality of the creek, near the site and downstream, is maintained at an acceptable level.
