Frontier Transportation, Inc.• • 425 Larch Road Page 3 of 3 of a sheen during one quarter of monitoring does not suggest a significant problem to EHD with conducting a pumping test in the former tank pit area, especially if the source of the sheen is impacted soil in the shallow saturated zone as speculated by BEAI. This issue requires further examination before EHD can concur with the proposed test design. • The EHD requires additional information on the free product sheen before approving or disapproving the proposed installation of passive free product skimmers in monitoring wells MW-2 and MW-21. Persistence of the sheen and a technically justifiable estimate of the recoverable free product volume should be provided to evaluate this recommendation. As the comments above indicate, BEAI has provided insufficient technical detail and justification for their proposed corrective action plans. The Interim Corrective Action Plan and the current AICAP have both failed to obtain EHD approval for much the same reason, and now a third must be submitted before the corrective action on your site can progress. Overdue and/or inadequate reports and work plans retard progress toward closure for your site. For your information, EHD has been informed that the State Cleanup Fund reimbursement program is scheduled to sunset in December 2010 and there are no current plans to seek a reauthorization for the program. To date, no remediation of impacted groundwater has occurred and impacted soil that is potentially still impacting groundwater remains on your site. Once cleanup has been initiated it may still take a number of years to adequately clean the site and groundwater and to perform confirmation monitoring and sampling. With the possibility that the Cleanup Fund will not be extended beyond the currently remaining 4 years of the program life, you are encouraged to make optimum use of the current reimbursement program and move your site toward closure as rapidly as is technically possible. By this letter, the EHD directs you to: • Submit all future quarterly reports within 60 days of conducting the quarterly groundwater monitoring event; • Submit to EHD no later than 14 August 2006 a corrective action plan addendum or revision that adequately addresses the concerns EHD expressed by letter dated 02 March 2006 and this letter regarding the ICAP and AICAP. Please contact Vicki McCartney, REHS, at(209) 468-3456 or vmccartney0a sicehd.com, if you have any questions regarding this letter.
