The ?OaS AHR is well organised and SCC did a <br />goad job at collecti?ag and reporting all required ir?onitoring data. <br />There eras na discharge from. any of the sediment ponds during the ?aa8 Water Year. The data <br />presented in the ???? AHR are consistent with the Probable Hydrologic Conseque?.ces ?PHC} . <br />p?ed1ctions far the mine site. Cutfall Dl ? is the only active nine water discharge point. According to <br />the data presented the increased TDS loading to the Colorado River i 0. ? 1 °Io ?rhich is equal to the <br />PHC predictlan of a ?.1 °Io increase. Cutfall 01 ? discharged ?. total of 73 tons of TDS to the nver <br />during the Year, which is bela?v the PHC prediction of 1,D0? tans additional salt load Surface v?ater <br />flows are measured on Cottanwaod and Rapid Creeks and an ?err? and Coal Creep drainages. T?.ere <br />eras na detectable effect ofrn1ning on flows in these creeks. Seep monitoring vas discontinued in Zaa? <br />per approval b? the Division.
