The test data for <br />all but one scenario were submitted to you via our letter of October 11, 1994. This letter <br />transmits the remaining test and the report from Golder Associates, Inc. summarizing all of the <br />test data. As stated in the attached report "[s]ince the input parameters that were used in the <br />referenced work are still valid and the theoretical critical failure surface did not occur through <br />the composite liner, additional stability analyses are not required." <br />If arty additional information is required, please let me know. Thank you for your assistance. <br />Environmental Affairs <br />Attachment: a/s (3 pp) <br />FILE: CC&VSTIP.002 <br />
