Hickenlooper <br /> Governor <br />Date: April 29, 2011 <br /> Mike King <br /> Executive Director <br />To: Susan Burgmaier <br /> Loretta E. Pineda <br />Director <br />From: Brock Bowles <br />RE: Yoast Mine (Permit No. C-1994-082) <br />Phase II Bond Release Application <br />Pursuant to your request, I have reviewed Seneca Coal Company's Phase II Bond Release Application <br />for the Yoast Mine, submitted February 23, 2011. My comments are organized by page number in a <br />way that would allow for direct insertion into a letter to Colowyo, if you so choose. <br />Let me know if you have any questions. <br />Phase II Bond Release Documentation <br />1. Page 2, Summary of Reclamation and Management History - On page 5 of the `Guideline <br />Regarding Selected Coal Mine Bond Release Issues' (April 1995), it is requested that the <br />applicant should include in the reclamation and management history the following points. <br />Please make a brief statement about each which were not included in the application: <br />a. Fertilizer type and rate (if not applied, document in text), <br />b. Shrub species planted, methods used, planting density and planting dates, <br />c. Mulch application type and rate (if not applied, document in text), <br />d. Livestock grazing, stocking rates and timing of grazing. <br />2. Page 4, Revegetation (Cover) Success, last paragraph - The text references Exhibit XX and <br />Attachment XX. Please amend text to make proper reference to the corresponding <br />exhibit/attachment. Make same changes to page 6, first paragraph. <br />3. Pages 4-8, tables 1-3, Revegetation (Cover) Success - The text and three tables do not <br />reflect the new data submitted by ESCO Associates to demonstrate revegetation success. <br />Please update the text and tables with the new data. <br />4. Attachment E, map 1 - When comparing map 1 to Exhibit A, vegetation sample points 20, <br />23, 26, 28 and 29 are clearly not in the bond release area. Sample points 15, 25 and 30 are <br />questionable and would depend on the direction of the transect.
