Mr. Dave Relos October 3, 2013 Page 5 of 7 has been defined Weaver Boos will prepare a Corrective Action Plan (CAP) or Remediation Work Plan (RWP). A specific scope of work and cost estimate for the preparation and implementation of the CAP cannot be provided until the site characterization has been completed. The CAP will be prepared in accordance with IDEM rules. The CAP will be prepared separately from the ISC/FSI Reports and may or may not be submitted to IDEM concurrently depending upon the magnitude of the subsurface impacts. Task 4 — Implement Corrective Action Plan/Remediation Work Plan (f necessary) Weaver Boos can implement corrective action if found necessary by the City based on site conditions. Task 5 — Request Closure/NFA (f necessary) Once IDEM approves the CAP (review will normally occur within 60 days of submittal), Weaver Boos will implement the CAP. Periodic progress reports may be required to be prepared and submitted to IDEM. Once the CAP has been completed then a closure report will be submitted requesting a No Further Action Letter (NFA) letter for the release. If no groundwater impacts are identified during site characterization, Weaver Boos anticipates that additional soil excavation and disposal will be considered as the preferred corrective action to be implemented in response to this incident should additional impacted soil be identified. If results of the ISC completed as part of Task 1 indicate that the soil and groundwater contaminant concentration do not exceed RCG screening levels then no further action will be warranted and the overall project will be deemed complete. Tasks 2 -5 will not be necessary. SCHEDULE Task 1 can be completed within 60 days of authorization. An estimate schedule to complete the remainder of the tasks outlined (if deemed necessary) is entirely dependent upon the extent of subsurface impacts identified. COST ESTIMATE Weaver Boos proposes to perform the work as outlined in Task 1 on a time and material basis in accordance with our fee schedule included with this proposal. We estimate the work can be completed for the budget summarized below. The budget does include three permanent
