-17- <br />• An alluvial ground water aq:u fer has been identified along Easc Salt Creek. <br />:4onitorinq wells established in the al.iuvivm indicate that alluvial cater levels <br />clvctuate seasonally in response to flow in East Salt Creek, which in tun <br />primarily responds to flow in tributary ephemeral streams. Data collected by <br />the applicant from t5e Salt Creek alluvial caviler t.9vs far indicate a sodium- <br />suifate type water, similar to the characteristics or the surface water in the <br />system, as would be eraected. :vo significantly adverse affects on ground <br />water resources arc anticipated For this operation. <br />Salt Creek Mining Company intends to monitor cyis aquifer upstream of ~HCClane <br />Canyon and downstream of .Hunger Canyon to identify any effects from mining. <br />Salt Creek Mining Company has committed to continue monitoring wells G./-3 and <br />G'A-4 in the Salt Creek alluvium quarterly. At t'~ese times, tte ;+a ter level in <br />tha wells will be measured and samples will be taken for ana_'yses of pK, <br />temperature,and specific conductance. The resu-'ts of this monitoring wi1_' <br />be submitted to the regulatory authority within 30 daus of data collect+'on and <br />analysis. <br />Narrow bands of alluvial-col_'uvial material extend about one mile vp Munger <br />Canyon from tke confluence with East Salt Creek. :Monitoring well G:/-4, which <br />is 40 feet deep and is Zocated at the lower part of Hunger Canyon, was dry in <br />April, Z98I during the period of the year of saowme_'t and highest precipicatien. <br />Also, test pies TP-1, TP-Z and TP-3, dug to a dept of 10 feet in tye Munger <br />Creek alluvium, had no traces of mottling and a eery slight increase in anisture <br />with dept's (see .Tables 4.1-1 tyrough 4.1-3).This, along with eye type of <br />vegetation present on the alluvium, suggests the absence of natural svbirrigaticn <br />in the Munger Creek alluvium. <br />The applicant propcses a rcnitoring Iola GW-5 to be installad in the :He:nger <br />Creek alluvium downsloee of the waste rock oi:e. T.':e Division recuires the <br />following stipulation to the permit to insure that baseline data is cbtaiaed <br />prior to the disposal of waste rock in the proposed pile: <br />SCpvlation No. r <br />SALT CBEEX :HIVING GOlfPANY SFfALL lS TALL AND .'}ONITCR T.YE ?ROPOSED <br />.HONITORI?!G i/E:..,' G:/-o ONE YEAR PRIOR '"0 °9E _ONS:'3CCTSG~V OFTilE <br />.HUNGER CANYON .HIVE :/ASTP ROC:< PILE. :/A TER •~UALITY SA:MP *-ES „,VD <br />:DATER L--PELS SHALL 9E TAKEN ~ARTERLI.
