TBAPP88 MINING INCE <br />RE D <br />July 10, 2014 <br />JUL 17 2014 <br />Mr. Jared Ebert <br />Colorado Division of Reclamation, Mining and Safety Division of Reclamation, <br />1313 Sherman St., Room 215 Mining & Safety <br />Denver, CO 80203 <br />Dear Jared: <br />(Subject: Trapper Mine (Permit No. C- 81 -010) TR -113 2013 Annual Redd matiou and <br />Hydrology Report, Adequacy Respoun 1 <br />In response to comments initiated on the April 24th adequacy review. <br />The Colorado Division of Reclamation, Mining and Safety requested additional <br />information concerning three items within the Annual Hydrology Report. Each item and <br />respective response is below. <br />1.) Enclosed is a letter from the Colorado Division of Water Resources (DWR) dated April 21, <br />2014. Several items were noted in the letter in regards to the compliance with the requirement of <br />the State Engineers Office. The first item is in regards to the stock water ponds present at the site. <br />The second item is in regards to the proper permitting required for the dewatering operations. <br />The third item is in regards to the types of well permits that need to be obtained for the <br />monitoring wells and exploration boreholes at the site. <br />Trapper will work with DWR concerning permitting of monitoring wells as applicable to <br />the site. Trapper currently holds the proper and adequate water rights for our current <br />operation. Trapper will further evaluate long term water rights when that becomes <br />necessary in the future. <br />2.) The iron (Fe) levels reported for alluvial monitoring well P -1 have varied throughout the <br />years, however in September of 2011 and September of 2013 the levels were reported to be 1.33 <br />and. 72 mg /1 respectively. These levels are higher than the Colorado Department of Health and <br />Environment Water Quality Control Commission, Regulation No. 41, The Basic Standards for <br />Ground Water, Table II standard for Iron which is .3 mg /l. Previous monitoring data for this well <br />show iron levels to be below this standard except for one event in September of 1999 when a level <br />of 1.24 mg /l was reported. This impact is not addressed in the 2013 Annual Hydrology Report <br />narrative; please explain the spike in iron levels of this well in 2011 and 2013. <br />In consultation with George Hoffman he states, "The total iron in well P -1 has varied <br />from very low levels to greater than 600 mg/1 for this very naturally common occurring <br />constituent. This shows that the natural variability of this constituent in the Pyeatt <br />alluvium is very large and indicates that 1.24 mg/1 might not define the upper natural <br />P.O.
