It is unclear as to what this means. (Page numbers are cut off.) A-90 Appendices (specific) App H, A7J020173, pg 6. The text indicates that Test America assumed that the TCLP analyses were not subject to USACE Louisville Chemistry Guidelines. The lab should not make assumptions like this. Any questions the lab has should be verified with the contractor (in consultation with USACE and Ohio EPA). A-91 Appendices (specific) App H, A7J030108, pg 28 – percent recoveries out of limits should be flagged. (Also applicable to several sheets in App H, L0711045.) A-92 Appendices (specific) Kemron TCLP non-volatile document control number sheets are not peer reviewed nor signed by a supervisor (L0710454, L0711045). These should be signed in future projects. A-93 Appendices (specific) Cover sheet for App I, L08010047 should read Ravenna Army Ammunition Plant (not Depot). A-94 Appendices (specific) App J, L0711258 – On the metals data verification checklist for Sb, Se, and Tl on page 1 – both yes and no are checked on question number 5. Clarify.

RTC for Draft LL1-4 Remedial Action Completion Report Cmt.# Page # Line # Comment necessary changes, fill in missing information, etc.. A-96 Boring Logs (General) On the future projects have an MI choice in the sample type box. A-97 Boring Logs (General) It appears as though several entries may have had information added to the field logs. If this is the case, the person annotating the logs should have signed their name, and initialed all the pertinent places. Examples: some of the writing appears different; and, DC initials on log LL3ss-092. A-98 Boring Logs (Specific) Several logs indicate that samples were collected from 0-2 foot depth bgs. Please clarify the interval selection. (Not all inclusive: sample #s LL1-ss-001; LL1ss- 002; LL1ss-003 – 716; LL1ss-003 2 nd ; and, LL1ss-003 MI, etc.) A-99 Boring Logs (Specific) Sample type missing from at least one log: LL1ss-004-704B. A-100 Boring Logs (Specific) Protocol for making changes was routinely applied throughout the field logs, but there are a few places where it was not utilized. Examples (not all inclusive): LL1ss-005- 705B; LL3ss-034 76 76; and, LL4ss-113- 006. A-101 Boring Logs (Specific) Not all the data boxes were filled in, for example the PID, O2/LEL, photograph #, calibration dates, weather and temperature. The logs should be completely filled out. Examples (not all inclusive): LL1ss-007; LL1ss-008; LL1ss- 012 4 th ; LL1ss-020; and, LL3ss-073. Recommendation No response required – please note for future work.

We will go over protocol with field crews to ensure changes are properly annotated on all logs. Excavation depths were based upon the depths of contamination specified in the LLs 1-4 Feasibility Study which was generally to the 0-2 foot interval. The depth of excavation exceeded 2 feet bgs if specified in the FS or if additional contamination was identified by field screening of confirmatory sampling. Comment noted. For record, sample was a soil sample. Comment noted. In future, we will go over protocol with field crews to ensure changes are properly changed/completed on all logs. Comment noted.
