We :have excavated to the limit of our'Iequipni'en. i <br /> The open tank hole continues to be a safety hazard which we,would lik'e,to <br /> eliminate. If additional soil clean-up is required, we will treat it in-situ. <br /> This will be determined by the installation of soil borings/monitoring wells. <br /> On August 9, you forwarded'.a draft of the approval of the workplan for the <br /> installation of 3 soil borings/monitoring wells. We will incorporate your 8 <br /> considerations into the workplan.
