I reviewed the recently submitted 2015 annual hydrology report <br />and no interpretation of the data was provided. Please define that this additional interpretation of data will occur <br />from 2016 forward. <br />With regard to groundwater level data, the operator referenced potentiometric surface maps in section 2.04.7 of <br />PAP from 1987. This does not address the need to provide data relevant to mining impacts on the groundwater <br />aquifers, which should be included in the AHR. Please provide the groundwater elevation data with an <br />interpretation identifying any trends and mine impacts. This can be accomplished with current annual <br />potentiometric surface maps and/or graphical representation and an explanation of the data. <br />Tabetha Lynch <br />Department (,)l NaU,vra,l } es(,x.Awes <br />https://mail.googl e.com/m ai I/u/0/?ui=2&i k=e29129fcb5&view=pt&search= i nbox&th=1537c3f9l c68753d&si m l=1537c3f9l c68753d 1/2 <br />
