Also the <br />overflow for the run-off catchment pond had some rip-rap <br />added to the top and downstream side of it to limit the <br />potential for erosion. <br />If you have any questions regarding this information please <br />contact me at 970-864-7347. <br />Sincerely, <br />COTTER CORPORATION <br />Glen Williams <br />Vice President of Mining <br />DRMS SR11 ltr <br />Cotter Corporation - West Slope Operations Telephone (970) 864-7347 <br />P.O.
