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 pstg. ASLLP witnessed the short 7" casing string <br />pressure drop 230 psig in 11 minutes. <br />This indicates a significant casing problem with both the long and short 7" casings. ASLLP <br />plans to plug both 7" casing strings with cement from the bridge plugs to the surface. <br />In accordance with Part II. E,1. of EPA Area permit C03858-00000 American Soda is <br />providing this 45 day notice of Abandonment of American Soda Well 20-32 (EPA <br />Permit Number C03858-04559). <br />11' you have any questions or require more information concerning this matter please <br />contact me at 970-285 -0407. <br />Delivering a Crystal Clear Advantage <br />www.americansoda.ccm <br />
