I I dolomite, light brown to white, thin-to-thickly bedded, variably fractured regional aquifer, and the Jordan Sandstone, which is a sandstone, white to yellowish, rme to course grained, loosely-to-well-cemented regional aquifer. Interim Remediation: TCAAP Groundwater Recovery System (TGRS) is in place (see Site 1). Draft Feasibility Study Recommended Alternative: Turn off TGRS, monitor. Marsden Lake is located on the eastern part of the site. The lake drains to the north and eventually to Rice Creek. Interim Remediation: No remediation has been conducted at Marsden Lake. Draft Feasibility Study Recommended Alternative: Annual monitoring and reasssessment of sediments, surface water monitoring, ecological evaluation. Sunfish Lake is located in the southeastern comer ofTCAAP near CSAH 96. Interim Remediation: No remediation has been conducted at Sunfish Lake. Draft Feasibility Study Recommended Alternative: Annual monitoriog and reasssessment of sediments, surface water monitoring, ecological evaluation. 3. Schedule of Remediation Based on the TCAAP environmental clean-up schedule of activities dated January 1995, the feasibility study for Operable Unit 2 (OU2) was scheduled to be complete by July 1995. This schedule was not met. For the purposes of this report, it has been assurned that the schedule is off by six months. This would mean that the remedial design of OU2 should be complete by January 1998. Remedial actions should be complete at OU2 by January 2002. Operation, maintenance and monitoring of the remedial systems is anticipated to continue for 80 to 90 years. The sites at TCAAP have been divided into three groups: those that should become available for re-use within one year, thosc that should become available for re-use in five years, and those that should become available in ten years. Thcse dates are approximations based on current site conditions, on the Draft Feasibility Plan's recommended altematives, and on the US EP A's "worst-first" policy, which requires that the most hazardous sites be cleaned while others, even if they are relatively easy or inexpensive to clean, wait their twn. Group I - Available in one year (1996-97): Sites B, F and J Group 2 _ Available in five years (2001-2002): Sites A, D, E, H, 129-3 and 129-5. Group 3 _ Available in ten years (2006-2007): Sites C, G, I and K. Many issues and unforeseen problems, including a shortage offederal funding, could delay the implementation of remedial plans. For example, the FY 1995 federal budget allocated $26 million to cleaning up TCAAP; however, this amount was later cut to only $2 million. It waslater increased back up to about $10 million, but there is no guarantee that sufficicnt funds will be budgeted in later years, nor that even budgeted funda will actually be available. Monitoriog wells, recovery wells, pump houses, SVE systems, etc. may be in operation long after the sites become available for re-use. Thc locations of some of these items have not yet been determined and may impact land use planning to a minor extent. Camiros. Lld./SEH, Inc./LHDL, Ltd. TCMP Framework Plan Page 29 Chapler II
