200809097 " Exhibit "B" Table 2 Notification of Hazardous Substance Storage, Release, or Disposal Load Line 2 and adjacent part of Tract 36 overlying groundwater plume Load Line 3 and adjacent part of Tract 34 overlying groundwater plume Name of Hazardous Date of Property Substance(s) Stored Storage, Description (S), Released (R), or Release, Remedial Actions or Disposed (D) Disposal Load Line 3 Explosive- 1942-45 There were no production operations and there is no known contaminated waste, 1950-57 soil contamination on the property outside the fenced Adjacent part of and residues including: 1965- 73 boundary of Load Line 3. Tract 34 2,4,6-trinitrotoluene overlying plume (2.4.6- TNT) Remediation of explosives-contaminated soil associated with Approximately cyclotetramethylene- Load Line 3 has occurred during multiple remediation 160 acres of land tetranitramine projects in 1987-88, 1994,2001-2003, and 2006. All (HMX) contaminated soil that was determined to exceed industrial hexahydro-I,3,5- risk soil remediation levels has been removed from former trinitro-I,3,5-triazine Load Line 3. (RDX) (S) (R) (D) A portion of Load Line 3 and an adjacent portion of Tract 34 overlie a plume of groundwater contamination. Groundwater Explosives breakdown contaminated with explosives is being remediated through a products include: pump and treatment plant. I ,3,5~trinitrobenzene (1,3,5-TNB),2-amino- Operation of the groundwater pump and treatment plant is 4,6~dinitrotoluene (2- expected to continue for some years into the future and will Am-4,6-DNT), and 4- not be discontinued until regulatory approval to do so is amino-2,6- requested and received. Annual groundwater monitoring and dinitrotoluene evaluation also continue. (4-Am-2,6-DNT) (R) In an effort to more quickly reduce OUI groundwater contaminant levels, a project involving subsurface injection of groundwater amendments began in December 2006 and is ongoing. The project involves pumping amendment solution under pressure into the aquifer through direct push rods. Temporary monitoring wells are installed for petformance monitoring at selected locations. Four months after injection activities are conducted, groundwater samples are obtained from the temporary monitoring wells and analyzed to determine the effects ofthe groundwater injection. The temporary monitoring wells are then abandoned. *The information contained in this notice is required under the authority of regulations promulgated under section 120(h) of the Comprehensive Environmental Response, Liability, and Compensation Act (CERCLA or 'Superfund') 42 U.S.C. ~9620(h), This table provides information on the storage of hazardous substances for one year or more in quantities greater than or equal to 1,000 kilograms or the hazardous substance's CERCLA reportable quantity (which ever is greater).
