CLOSURE REPORT (CLOP) Detailed CLOP Required For Release Closure Similar to PMZ CAP
RELEASE CLOSURE REFERENCE DOCUMENTS Technical Guidance 9: Petroleum Release Closure Categorization Appendix A Petroleum Closure Checklist RBCA Guidance Soil, Groundwater, and Indoor Air RBSLs Conversion of TPH/TEH (GRO/DRO) data to Petroleum Fractions (Section 3)
COMMON ISSUES Confirmation Groundwater Sampling Loss of Source Area Wells Lack of DCA/EDB Groundwater Analytical Data Lack of Adequate Confirmation Soil Sample Data Potential VI Assessment No Assessment of Landfarm Soil Exceedances of Soil Direct Contact RBSLs!
SUGGESTIONS FOR CONSULTANT REPORTS TO IMPROVE CLOSURE PROCESS Cumulative Soil Data Tables Indicate Well/Boring Locations Relative to Source Area Convert GRO/DRO Data to VPH/EPH Fractions Compare Sample Data to Direct Contact Excavation RBSLs Complete and Detailed Site History Site Map with all Historical Features Scale Bar for all Maps Appendix with all Site Well/Soil Boring Logs
CONCLUSION Complete Closure Checklist (Appendix A) in Technical Guidance 9 Before Requesting Closure Check All Historical Soil Data And Compare Soil Sample Analytical Data to Table 4 Master for All Potential Tier I RBSLs for Soil (Especially Direct Contact Construction 2-10 feet) Calculate Site-Specific Tier II Direct Contact Excavation RBSLs as necessary
