Assuming a <br /> potential reimbursement cap of $2,000,000 (two leak events at one- <br /> millon dollars each), some $198,199 remains for potential <br /> --imbursement. <br /> He have been previously informed, the TWC LPST Fund is depleted, <br /> 1 payment of potential reimbursement for site remediation <br /> .penditures may be long-delayed. ¡ <br /> ..le understand that cleanup criteria for petroleum-contaminated <br /> soils-groundwaters are currently being reviewed and revised by the <br /> TWC, which could result in' more lenient residual levels of <br /> contamination allowed. Therefore, site closure time could be <br /> reduced significantly, or , at 'least, partial site closure <br /> (plugging of some bore-holes) may be ordered. <br /> operational project costs during Fiscal year 1991-1992 (contractor <br /> operated until April 5, 1992) were $649,185. operational costs for <br /> Fiscal Year 1992 - 1993, (with last tTH'O quarters conservatively <br /> estimated at $15,000) will be some $73,000, or a reduction of <br /> $576,185 from the previous year.
