This letter was in response to the Division's adequacy letter of <br />December 30, 1999. <br />The Division has the following comments/suggestions before the Division can approve the Temporary Cessation <br />Application; <br />1. The operator states that ITEC will use the volume-depth curves from the 1998 tailings pond design to set the <br />limits of the tailings pond surface levels to insure that the pond has a safe freeboazd at all times. The operator <br />will need to specify the freeboazd that will be maintained and at what point the operator will need to consult <br />with the Division to reinstate the evaporation and land application procedures (this was a commitment as a <br />result of corrective actions for a violation). The Division recommends afour-foot freeboard in the tailings <br />pond at which the operator will need to consult with the Division to reinstate the evaporation and land <br />application procedures. <br />2. During the term of Temporary Cessation, the operator should commit [o inspecting the water level in [he <br />Hazel A on a monthly basis. A record of water levels will need to be maintained and available for inspection <br />by [he Division. <br />Please respond to these items by November 8, 2002.
