<br />DIVISION OF MINERALS AND GEOLOGY <br />Depanmem of Nalu ral Resuurces <br />1 31 J Sherman 51., Rpom ? 15 <br />Denver, Culuradn 80203 <br />Phune: 13U31 866 3567 <br />FAX: U03)83?-B1U6 <br />DATE: November 1, 1996 <br />TO: ErioxCrosby <br />FROM: Larry Routten <br />RE: Meek Mines (C-91-032) <br />TR-11 ~ ~-I~ <br />STATE OF COLORADO <br />I~~ <br />DEPARTMENT OF <br />NATURAL <br />RESOURCES <br />Roy Romer <br />Governor <br />lames S. Lochhead <br />E~ecuhve Director <br />Michael B. Long <br />Division Director <br />I reviewed Enron's responses to our adequacy questions, related to changing the <br />revegetation success standards. Their responses are appropriate and I recommend we <br />approve the revision. <br />I also looked at the proposed seed mix Enron gave you for the reclaimed Rienau pond area. <br />My first recommendation would be to use the approve seed mix in the permit, since that has <br />been very successful in past reclamation efforts at the mine. If the landowner has a strong <br />desire to use a different mix on this limited area, that may be appropriate. The submittal <br />includes "bluestem". It is not clear which bluestem is intended to be used. However, both <br />big and little bluestem (Andropogon gerardi and Schizachyrium scoparius) are warm season <br />grasses adapted to sandy soils on [he plains. Their chance of success at the Meeker Mine <br />site is questionable, at best. <br />Also, using the proposed species and rates without the bluestem, Enron would be putting <br />out 164 seeds per square foot. We typically recommend seed rates of about 40 seeds per <br />square foot for critical area plantings, based on NRCS recommendations. <br />c:\wp51\110196 <br />
