Exxon proposes <br />a slope stability survey monitoring program to verify the stability of <br />the existing fill mass during the Interim program. Five survey monuments <br />have been installed and will be surveyed on a monthly basis to determine <br />whether any detrimental movement might be occurring. Exxon commits to <br />the monthly submittal of the survey monitoring results to the Division. <br />This program is acceptable as proposed. Ns I mentioned in my memo to you <br />dated February 18, 1983, with the installation of these monuments and the <br />initiation of the monthly survey monitoring it is appropriate to ddem <br />stipulations 1 through 3 placed upon the interim plan as satisfied. <br />cc: Joe Zalkind <br />Doc.
