<br />' Lyons Pit, Interior Berms 2 January 28.2000 <br />the wording in the permit had to take the form of unequivocal commitments to 150-foot minimum crest <br />widths for interior berms in the two locations and 188-foot crest widths for all other interior berms. <br />One point that was not discussed with Mt. Pazker is that the berm associated with the cement plant pond <br />is going to be a constructed embankment rather that a berm formed of native material left in place. A <br />150-foot wide crest on a constructed embankment will result in an unusually lazge constructed <br />embankment impounding a rather small pond. The Operator may want to consider a naaower <br />embankment crest with an incorporated spillway that could be used to pass water through the <br />embankment in either direction. <br />cc: Tom Schreiner, DMG . <br />c:\windows\pawnaNyons2.doc <br />t <br /> <br />i <br />1 <br />~. <br /> <br /> <br />1 <br /> <br /> <br />.~ .~-~:T" ...,,~ <br /> <br /> <br />
