June 17, 2014C-1982-057/Seneca II-W MineJHB <br />Ponds : <br />Katryna was conducting quarterly pond inspections and water sampling throughout the permit area. The inspector <br />accompanied her to Pond 017 and Stream monitoring point WSH9 (Identified by Katryna, Exhibit 7-1A <br />“Hydrologic Monitoring Map” identifies this point as SW-SW2-SG9, Upper Hubberson Gulch) to observe SCC’s <br />sample techniques. <br />Katryna rinsed the samplingvessel 3 times prior to collecting the sample. The sample is collected at the discharge <br />from the primary riser at pond 017, and at a free falling location on the drainage upgradient from pond 017 (SW- <br />SW2-SG9). Flow was measured at the outfall from Pond 017 flume. The staff gauge at the flume measured 0.30. <br />Katryna measured the flow at the flume as 0.37 ft. The flume has determined to not be level.Pond 017 flume also <br />has a Steven’s recorder. Katryna changed the recorder paper on this as well. <br />Fieldparameters are measured from the sample collected in the jug. The pH meter was allowed to come to <br />equilibrium in a sample of the water. The Division’s pH meter had not been calibrated (Inspector din not have any <br />calibration solutions) and measured considerably lower than SCC’s measurement. SCC measured 8.4 pH. <br />Katryna had calibrated her pH meter that morning in the office. DRMS pH meter measured 6.5 pH, which is <br />believed to be erroneous due to a failure to properly calibrate the meter. <br />Katryna pouredwater from sample jug into laboratory sample bottles, labeledand stored in cooler, to be delivered <br />to ACZ laboratory in Steamboat Springs later in the day. This sampling methodology is acceptable and meets the <br />Water monitoring protocol found in Tab 15;Appendix 15-3A. <br />Culvert PM-18 is completely plugged at inlet to Pond 017(photo2).A spring emanating from a slump to the east <br />of Pond 017, runs along the ditch and should enter Pond 017 via Culvert PM-18. Flow from the spring is cutting <br />across the road alongside Pond 017. A portion of the road at the Culvert PM-18 outlet has collapsed into Pond 017 <br />(Photos1 and 3). This condition was reported in the DRMS May 21, 2014 inspection report. SCC has not yet <br />cleared the inlet of Culvert MP-18, or repaired the road alongsidePond 017.. <br />Pond 016 was discharging. Katryna collected a sample from this pond but the inspector did not accompany her. <br />Pond 016 embankment appeared stable. No problems were identified with Pond 016. <br />Pond 005 was discharging. No problems were identified with Pond 005. <br />Pond 009 was inspected. Cattle were grazing on the embankment and at the south end of the pond. Houndstongue <br />was observed around the pond. Weed control efforts should continue at this location. Pond 009 was not <br />discharging. Waterlevel was approximately3 to 3 1/2 feet below the discharge elevation. <br />Pond 015 was inspected. A porcupine was hanging out under the Pond 015 flume. <br />Drainages:PM-2A was traversed from the northern end at Culvert PM-19 all along to the southern extent at the <br />ridgeline to PM-1A. There are 4 structures in PM-2A drainage: <br />Number of PartialInspection this Fiscal Year: 8 <br />Number of CompleteInspections this Fiscal Year: 4 <br />314 <br />Page of <br />
