| 7/13/2010 | Document, Report, or Work plan Review - other | Pump Station 3 Fire Training Area 2010 Site Remediation Workplan received June 15, 2010. Conditional approval conveyed via email on 6/18/2010 stipulating that highest PID reading or DRO result should also be analyzed for PAH. Followup letter on today's date stating that VOC with TICs should also be added to the analyses of all samples collected as Halon compounds (bromofluorochloromethanes) are possible contaminants of concern with fire extinguishing chemicals as potential sources of contaminants. | Keather McLoone |
| 2/17/2011 | Document, Report, or Work plan Review - other | Date of receipt of Pump Station 3 Fire Training Area 2010 Site Remediation Report. Review included laboratory data review checklist. Excavation of ~ 90 cubic yards of contaminated soil was followed by confirmation samples which were analyzed for GRO, DRO, RRO, BTEX, VOCs, and PAHs. All results below most conservative criteria. Tentatively identified compounds (TICs) not reported, however this should not have a significant impact as normally reported halomethane were not detected. | Keather McLoone |
