This letter report presented the results of the <br />operator's annual swell factor determination. Consistent with the past seven <br />years, the report verified an observed swell factor of 25%, essentially <br />equivalent to the original permit projection of 24%. The methodology for <br />completing the determination complies with earlier precedent. The technique <br />and results are clearly presented within the report. I recommend acceptance <br />of the swell factor report, as submitted. <br />Further, the operator requests that Stipulation No. 2 be declared satisfied <br />and that the requirement to complete future determinations be forgiven. <br />I concur with the operator's conclusion that they have definitively determined <br />the swell factor at the Kerr Mine. Therefore, I also recommend that the <br />Division consider Stipulation No. 2 satisfied, and that the Division approve <br />the termination of swell factor monitoring by the operator. <br />cc: Susan Mowry <br />
