112. I have field checked and agree there are the three AVFs you identified in your comment. I will have MCC add text that identifies them. Also, I will check the potential AVF along the upper mainstem of Minnesota Creek mentioned in your March 3 email. 114. I believe this comment is being handled by Byron and Dan H. 116 and 116a. I am satisfied with MCC's responses and the revised pages 2.06-9 through 11 (copies in attached PDF file). 120. I am satisfied with MCC's response that current AVF monitoring is adequate, for the following reasons. North Fork AVF -Oxbow Mining monitors North Fork surface water immediately downstream from the headgate of the Fire Mountain Canal (site NF-3). This site is within a subin•igated portion of the modern-day alluvial valley, approximately 2 miles upstream from the agriculturally productive North Fork AVF. Data from site NF-3 enables identification of material damage to the quantity and quality of water supplying the North Fork AVF. MCC's contribution to impacts can be identified from MCC's monitoring of its CDPS outfalls, approximately 2,5 miles upstream from NF-3. Significant inputs from the West EIk Mine would occur only from the part of the mine that is upstream from Somerset, as the Lone Pine Gulch area no longer has a pumping site and has been Phase II bond released. Upper Minnesota Creek AVF - MCC financially supports the USFS monitoring station that is located on this AVF. This station and MCC's monitoring upstream from the AVF would enable identification of material damage to the quantity of water supplying the AVF. Material damage to water quality would not be expected because the mine does not propose to discharge mine water to this drainage. Lower Minnesota Creek AVF - MCC financially supports the USGS monitoring station on this AVF. This station and MCC's monitoring upstream from the AVF would enable identification material damage to the quantity of water supplying the AVF. Material damage to water quality would not be expected because the mine does not propose to dischazge mine water to this drainage.
