MANAGEMENT <br />The DRMS' letter dated August 6, 2009 transmitted its adequacy review for the <br />referenced minor revision. On behalf of Bowie Resources, LLC, (BRL), following are its <br />responses to the DRMS' comments and concerns. <br />1. The DRMS' $7,249 reclamation estimate is acceptable. <br />2. MSHA approval is not required to pump nitrogen into the mine. <br />3. Amended page 2.05-5 provides a narrative of the intended use of nitrogen in <br />the mine. <br />4. During a test run of the compressors and nitrogen generator, noise levels <br />were measured at 57.5 dba approximately 25-feet from the machinery. The <br />nitrogen generator will run intermittently as required to supply necessary <br />nitrogen to the mine. <br />Amended page 2.05-5 is enclosed. <br />Sincerely, <br />L?ttover, P.E. <br />Consulting Engineer <br />Cc: Bill Bear, USDA-FS
