In a letter dated 7 December -1989,,, your consultant, <br /> Versar, Inc. , requested a 90 day extension to the,� dead.line for submittal of <br /> the requested work plan. The extension is being requested to allow time for <br /> �. completion of construction at the site. <br /> Ir <br /> ,i <br /> Because submittal of the work plan is not dependent on completion of <br /> construction, we do net agree that a 90 day extension ;is necessary or <br /> warranted.

After construction is completed„the ground water <br /> investigation can proceed with any necessary modi_'ficat`ions. <br /> Petroleum hydrocarbons have also been detected in' soil; at your site. To avoid <br /> possibile destruction or damage to planned surface structures, the extent of <br /> soil contamination should be determined and a soi-] remediation plan developed <br /> prior to site construction. Therefore, we -request that you submit a soil <br /> remediation proposal with the ground water investigation work plan. <br /> _ The <br /> ground water investigation work plan should also ,include a cope of your-site <br /> construction plan showing the proposed locations ;,'for the ground viater <br /> -- —,,monito.6na_welIs. .,...� <br /> !
