A 2000 gallon steel tank for storage of Sodium Hydroxiq <br />is located in the Flume House, as well as 2 flocculent tanks. Any spills in the No. 1 Flugg <br />House would report to No. 1 Pond, located just to the north. Mitch Lapp reported t <br />concrete curbing would be installed at the man -door and overhead -door in the Flume House <br />more efficiently direct any epille into the open ditch in the floor that conveys water to t <br />ponds. Mitch Lapp also reported that more sophisticated electronic alarms and contr <br />systems will be installed in the Flume House. <br />The No. 1 Shaft House water treatment facilities were inspected. A 6000 gallon steel ta5 <br />for storage of Sodium Hydroxide is located in the No. 1 Shaft House. The tank is located <br />a curbed, concrete floor that would contain any spills. Mine water is pumped up No. 2 Sha <br />to a large surge tank located east of No. 1 Shaft House. The mine water is piped from t <br />surge tank to NaOH feed in the shaft house, then to a series of frac tanks located outsi <br />the shaft house for mixing and metals precipitation. The frac tanks are proposed to be <br />eliminated from the system, but will remain as a bask -up facility, once the new pond is <br />constructed and certified. <br />Water treatment sludge is piped from the frac tanks to No. 1 Pond. No. 1.1 and No. 2 Ponds <br />also contain water treatment sludge. At thin time, none of the surface s ;orege facilities <br />at the Henderson Mine are designated for permanent sludge disposal. <br />Storm water detention basins and outfalle located at the north end of the mine yard were <br />visited. A ditch leading into the storm water basin at the east end of the yard needed to <br />be cleared of soil excavated during pond construction. The route of the mine yard upland <br />diversion ditch wan observed. The ditch empties into Wept Clear Creek below No. 2 Pond. <br />The location of the new ground water monitoring well, designated GW - 2, was inspected. The <br />new well is collared south, and above West Clear Creek, just up gradient from long - term <br />surface water monitoring point designated HE -3. The well log and completion details are <br />forthcoming from the operator. <br />I 6,E Contact Address cc: Carl Mount, DMG <br />❑ CE <br />NAME Anne Ihlenfeldt 0 BL <br />OPERATOR Climax Moivbdenum Company 0 FS <br />STREET P.O.
