<br />ambient -based standard for iron (8.06 mg /1) was exceeded
<br />with a value of 10.2 mg /1. This well exceeded the standard
<br />for iron (10.4 mg /1) in 2012. Well DCAL -02 did not exceed the
<br />TDS standard, 3195 mg /1.
<br />11. Sampling frequency
<br />Appendix 15 -3a, Table 1
<br />The report indicates that all frequencies were met.
<br />surface water
<br />of CDRMS mining permit
<br />C- 1982 -057
<br />12. Parameters to be
<br />Appendix 15 -3a, Table 2
<br />Parameters to be sampled are conductivity (umhos /cm), pH
<br />sampled at surface water
<br />of CDRMS mining permit
<br />(units), temperature (C), total recoverable iron (mg /1),
<br />sites
<br />C- 1982 -057
<br />dissolved manganese (mg /1), total mercury (ug /1), dissolved
<br />nitrate (mg /1), dissolved nitrite (mg /1), total ammonia (mg /1),
<br />dissolved selenium (ug /1), dissolved sulfate (mg /1), total
<br />sulfide (mg /1), total suspended solids (mg /1) and total
<br />dissolved solids (mg /1). All required parameters were
<br />analyzed. All parameters were met.
<br />13. Filing frequency of pond
<br />CDRMS regulation
<br />Ponds 005, 006, 009, 015, 016, and 017 are the sediment
<br />reports
<br />4.05.9(17)
<br />pond associated with C- 1982 -057. Quarterly pond
<br />inspections were conducted within the appropriate quarter.
<br />14. Timely filing of pond
<br />CDRMS regulation
<br />Quarterly pond inspection reports were submitted and
<br />reports
<br />4.05.9(17)
<br />received by the Division within an appropriate timeframe.
<br />15. Content of pond reports
<br />CDRMS regulation
<br />All required information was addressed on quarterly
<br />4.05.9(15)
<br />sediment pond inspection in water year 2013.
<br />16. Sampling frequency of
<br />Appendix 15 -3a, Table 1
<br />Ground water samples are collected from WHAL7 -2, WOV14,
<br />ground water monitoring
<br />of CDRMS mining permit
<br />WW14, WO17, WW17, WWC17, WOV25, WW25, WSOV25,
<br />wells
<br />C- 1982 -057
<br />WSC25, WWCOV25, WWC25, WWCU25 and DCAL -02 on an
<br />annual basis.
<br />17. Parameters to be
<br />Appendix 15 -3a, Table 3
<br />Parameters to be sampled are conductivity (umhos /cm), pH
<br />analyzed in ground water
<br />of CDRMS mining permit
<br />(units), temperature (C), dissolved iron (mg /1), dissolved
<br />samples
<br />C- 1982 -057
<br />manganese (mg /1), dissolved fluoride (mg /1), dissolved nitrate
<br />(mg /1), dissolved nitrite (mg /1), dissolved selenium (ug /1),
<br />dissolved sulfate (mg /1), total suspended solids (mg /1), and
<br />total dissolved solids (mg /1). All parameters were met.
<br />18. Basic Standards for
<br />CWQCC regulations 41.4
<br />The Seneca II -W Mine did not generate significant amount of
<br />Ground Water
<br />and 41.5
<br />Ieachates in 2013. Four groundwater wells exceeded the
<br />manganese standard (0.2 mg /1) in 2013. As mentioned in the
<br />above item number 8 above, in soils with a high pH a
<br />standard of 10 mg /I would be more appropriate than the .2
<br />mg /1. In 2013 none the Seneca II -W wells displayed a value
<br />higher than 1.57 mg /1. Three groundwater wells excceded
<br />the iron standard (5.0 mg /1) in 2013, including well DCAL -02.
<br />The pH standard (6.5 — 8.5) was excceded at one site.
