As such, MCC has already responded to each of <br />the Division's '`requests" in the form of a letter dated February 10, 1997 (copy <br />attached), during the meeting with Jonathan Kelly of Wright Water Engineers, Inc. <br />(WWE) and you regarding MCC's plans for the 1996 AHR, and during several <br />meetings with MCC and/or WWE to discuss plans for and responses to the PHC <br />(TR#80). <br />S~ kt ~Q 1.

Mine discharges will be monitored, flows <br />estimated or, where practical, measured, and annual samples collected." In <br />addition, page 2.05-82, "Annual Hydrololry Report" states that the AHR <br /> <br />
