***Tuesday, June 29, 2004: (1-OSC, 2-PST, 2-START, 9-ERRS, 8-Cascade Abatement, 1-Advantage). Abatement subcontractor continued abatement of friable ACM and ACM floor tile from 204. ERRS began to load non-ACM demolition debris for disposal at the local landfill. ERRS also began to perform final cleaning around demolished buildings by consolidating debris piles and by picking up loose pieces of ACM debris on the ground. ERRS and the abatement contractor wrapped and removed ACM steam pipe from building 220 (currently FAA property) and ACM steam pipe from the site that had been dumped on BLM property. Frank Messina of Oregon DEQ visited the site. START-2 continued perimeter and area air sampling, and USCG PST continued site safety and medical monitoring. Site work stopped at 16:30 because of lightning and thunderstorms.
***Wednesday, June 30, 2004: (2-OSC, 2-PST, 2-START, 9-ERRS, 8-Cascade Abatement, 1-Advantage). Abatement subcontractor finished abatement of 204. START and Advantage visually inspected the abated 204 and then performed clearance air sampling. Abatement subcontractor also abated ACM floor tile from building 133. ERRS continued to load non-ACM demolition debris and continued final cleaning around demolished buildings. ERRS also excavated additional PCB-contaminated soils from 200. OSC Andy Smith arrived on site, and Dave Anderson of Oregon DEQ visited the site. Andy Smith, ERU Health and Safety OSC, conducted an internal Health and Safety audid. START investigated a potential radiation source - a metal door from 165 that had a radiation warning label. The results were less than 0.1 millirem per hour (mR/hr), which was comparable to background results. START continued perimeter and area air sampling and performed immunoassay field testing for PCBs on soil samples from excavated areas of 200, 133 and 206. USCG PST continued site safety and medical monitoring. A metal scrapper (Wurdinger Recycling) mobilized a trailer-mounted metal crushing unit to the site. Site work stopped at 17:00 because of lightning and thunderstorms.
***Thursday, July 1, 2004: (1-OSC, 2-PST, 2-START, 9-ERRS, 8-Cascade Abatement, 1-Advantage, 2-Wurdinger Recycling). Advantage analyzed the clearance samples from 204, which were less than the clearance limit, indicating that the abatement was successful. ERRS and the abatement subcontractor wrapped and removed the remaining sections of ACM steam pie that were located at building 204. ERRS excavated additional PCB-contaminated soil from 200, and then loaded PCB-contaminated steel and soil into trucks for off-site transportation and disposal. ERRS continued to load non-ACM demolition debris and continued final cleaning around demolished buildings. Wurdinger Recycling began to crush metal scrap for off-site transportation and recycling. START collected additional samples from excavated 200bottom of 200 excavation, and sends these and other samples to Severn Trent for PCB analyses. START continued to perform ambient air monitoring. OSC Szerlog, Advantage, USCG PST, and START Hall demobilized from the site.
***Friday, July 2, 2004: (1-OSC, 1-START, 9-ERRS, -Cascade Abatement, 2-Wurdinger Recycling). Abatement subcontractor cleared and removed ACM debris from around site buildings. ERRS covered and secured remaining PCB-contaminated soil and debris piles at 200, 133, and 206. ERRS also consolidated scrap metal piles for scrapper and covered manholes and other physical hazards. Wurdinger continued metal crushing for off-site transportation and recycling. ERRS demobilized one of the command post trailers and staged loaded roll-off boxes (2 with friable ACM and 2 with ACM debris) for later off-site transportation. OSC and START marked slabs and foundations with building numbers for future identification. START performed ambient air monitoring and documented (notes and photographs) the final condition of the site. Abatement subcontractor, ERRS, and OSC Smith demobilized from the site.
***Saturday, July 3, 2004. (1-START, 2-Wurdinger Recycling). Wurdinger continued metal crushing and recovery. START completed the marking of building foundations and site documentation (including photographs) of final site condition. START demobilized from the site.
