a) On page 2-44 of the application, it is stated, "there are no adjudicated groundwater rights within more than two miles of the proposed permit area". The Division concurs, however this does not exclude the operator from groundwater quality protection. There is an existing alluvial well in Section 29 permitted for domestic use (Permit No. 256862). Since there is a domestic use well within relatively close proximity to the mining activity and located in the East Salt Creek alluvium, "Domestic Use -Quality" classification of the Basic Standards For Ground Water may apply to the specified azea of the mining activity and East Salt Creek alluvium. On page 2-45, it is stated, "Since there are no groundwater rights adjudicated in the area of the mine there will be no impact on any water interests." This may not be the case with regard to groundwater quality protection. There is no mention of the East Salt Creek alluvium being identified as an alluvial valley floor in the PHC discussion. Section 2.4.2.1 Probable Hydrologic Consequences and Appendix N should be revised to include a discussion of the probable effects mining may or may not have to the quantity and quality of groundwater in the East Salt Creek alluvium. Please revise Section 2.4.2.1 of the application to include a discussion of the existence of one domestic use well located approximately one mile southwest of the confluence of McClane Creek and East Salt Creek. Please revise Section 2.4.2.1 and if appropriate Appendix N to include a discussion of the identification of East Salt Creek alluvial deposits as an alluvial valley floor, and describe the effect that the mine (including mine water discharge at Outfall 002) has on the groundwater hydrology of East Salt Creek alluvium. b) In the table given on page 3 of Appendix N, the values given in the column labeled "% Increase/Decrease" are incorrect. The values given in this column are in fact fractional rather than percent increases. Please revise the values in the last column (multiply by 100) to show actual percent increase, and submit an amended table. c) Please update the discussion in permit Section 4.1.2.5 regarding effects of the operation on the East Salt Creek alluvial valley floor to incorporate the updated PHC projections. Amended narrative should address effects to both alluvial groundwater and to East Salt Creek surface water used to irrigate the cropped AVF parcels depicted on Figure 4.1-2.
