However, the surface location had to be moved to satisfy EPA UIC permit <br /> requirements. NS will not drill the 17H-1V SSMW well and will drill the 17H-E SSMW on a new <br /> pad to be built further east over the 17H-IR-E well path. The bonding is in place to cover the <br /> well but additional bonding will be required to cover the new location. The 17H-E SSMW will be <br /> cased to total depth and not be open to any hydrologic interval. It will be filled with water for <br /> periodic geophysical logging purposes. <br /> Please find attached: <br /> 1) DRMS Form — Request for TR Cover Sheet <br /> 2) Location Map <br /> 3) Proposed Well Completion Diagram <br /> 4) Plat, cut and fill diagrams and location photos <br /> 5) Check number 7871 in the amount of$1,006.00 <br /> Should you have any questions or comments, please contact me at (970) 254-1224 or <br /> (970) 216-1010 (c), or Kirk Daehling at (970) 456-1268. <br /> Regards,, <br /> 9�f�� <br /> Gerald J.
