Upon the completion of the <br />installation of the bridge plug, ASLLP pressured the long 7" casing string to 600 psig. The short <br />7" casing pressure also increased to 600 psig. ASLLP witnessed the short 7" casing string <br />pressure drop 230 psig in 11 minutes, <br />This indicates a significant casing problem with both fhe long and short 7" casings. ASLLP <br />plans to plug both 7" casing strings with cement from the bridge plugs to the surface. <br />This work will be completed after the 45 day notification to EPA has been met. <br />If you have any questions or require more information concerning this matter please <br />contact me at 970-285 -0407, <br />Si~nce/re~ly,f/~,/, <br />Ed-C~fSTey~ <br />Environmental Health <br />and Safety Manager <br />cc: Kent Walter/BLM <br />Elisabeth Evans/EPA <br />Delivering a Crystal Clear Advantage <br />www.americansoda.com <br />
