Hickenlooper <br />Governor <br />Mike King <br />Executive Director <br />Loretta E. Pineda <br />Director <br />The Division of Reclamation, Mining and Safety has received a revision for the Bowie No. 1 Mine. <br />The revision was called complete on August 27, 2012.

This <br />technical revision will change the lining material for the upper segment of the ditch, and increase <br />the required diameter of riprap in the upper, middle and lower segments of the ditch. Ditch 7 <br />currently lies within the disturbance boundary and no change in disturbance area, permit boundary <br />or affected area is proposed. <br />This revision is available for review at the Paonia Public Library, 2 Third Avenue, Paonia, CO <br />81428. <br />If you have any questions, please contact me. <br />Sincerely, <br />Aa4--)L <br />Brock F.
