~oosos9o7 Exhibit "B" Notification of Hazardous Substance Storage, Release, or Disposal Load Line 4 Name of Hazardous Date of Property Substance(s) Storage, Descr[ption Stored (S), Release, Remedial Acfians Released (R), or ar Die sea D Dis asal As a recruit of these efforts, the property within the boundary of Load Line ~ received 5X certification, except far the boiler house, which was excluded from the soaps df work far MEG clearance efiarts. In 2t7D5, field testing in the boiler house indicated that there was no explosive contamination vr• residue present, Asbestos-containing rrraterials were removed from the bailer house and the bailer house buckling was denwiished that same year. 1=allowing demolition, the srn7 under the fam~sr baiier house location was field tested far the presence of explosves. No explosive contamination ar residue was present in the said. In 2~7, the iocafions of former buildings on Load Line 4 were sampled and analyzed far explosive chemicals contamination, Work to remove evil that was contaminated at levels exceeding the CHAAP industrial risk soil remediatlan levels began in July 2D07 and was completed in November 2DD7. A portion of LL ~ overlies groundwater contaminaYion consisting . of explosive chemicals; however this contamination does net exceed established groundwater dleahup standards. Na cleanup of groundwater an Load Line 4 is required, although annual manilaring of bw levels of groundwater contamination continues. toe {p) Unknown An asbestos-containing transits water line was undavered during field screening of water supply pipes in 2DD5. The pipe was tested for the presence of explosives {the test was negative), then allowed to remain in place and covered aver again. The report ~erttifies the pipe as being the northeast water main feed line for LL 4, located within the northeast boundary of Load Line 4. The pipe Is of 7 feet bgs and is 12 inches in diameter. The estimated length of this pipe 'ts unknown. The transits water line does net present a health hazard while buried underground because asbestos fibers are not being released to the air. Along with the utilities that wen: known from the as-built drawings, previously unknown utilities that were discovered during the 2DD5 geophysical investigatlpn were inspected and field scxeen~ fir explosives. One of these pipes is described as a burr pilvert pipe insulated with asbestos. The insulation was sampled and analyzed and determined to contain 4D% amosite asbestos. The asbestos insulation is wrapped around a 6-inch diameter pipe and the pipe is estrmated to be 1,DDD feet in length. This pipe runs from the east perimeter fence tp the location of farmer Building L-1 D within Laad Line 4. Through visual inspection and field screening, it was determined that the pipe did not contain any explosives residues and the line was left . in place with the excavation backfilted. The asbestos insufakidn does not present a health hazard while buried underground because asbestos fibers are not bein released to the air.
