Levine•Fricke•Recon ENGINEERS,HVDROGEDLOGI5TS 8 APPLIED SCIENTISTS • We have contacted various property owners and their tenants to obtain permission to conduct Remedial Investigation and/or Interim Remedial Action (IRA) activities on adjacent properties. Access negotiations began in October 1996 and are ongoing. • A site walk with the contractors for the storage and operations compound (SOC) construction was conducted on October 19, 1996. Construction of the SOC had originally been scheduled for November 1996. Because of concerns raised by Payless about the interpretation of certain historical property records and potential impact on holiday business operations, the SOC construction schedule was postponed. Historical property records for Lincoln Center were obtained from Payless and reviewed by counsel for the SDCDs and counsel for Lincoln Properties, Ltd. (LPL). As a result of their review, the SDCDs and LPL believe that the SDCDs can construct the SOC on LPL property. To avoid any impact on the holiday shopping season, SOC construction was rescheduled to begin January 13, 1997. Discussions with Payless and their landlord, the Fahns, are ongoing to assure that any concerns in connection with the planned SOC construction are resolved before the rescheduled construction start-up date. In addition, the following Phase I IRA field scoping activities were conducted in October, November, and early December 1996: • Monitoring wells MW-100 and MW-101 were installed in the vicinity of monitoring well MW-11 on October 30 and 31 and November 13 and 14, 1996, respectively. These wells were developed and sampled on October 31 and November 14, 1996, respectively. Monitoring well MW-100 was also sampled during the fourth quarter 1996 sampling event on November 12, 1996. • Eleven cone penetration testing (CPT) and push-in polyvinyl chloride piezometer (PIPP) borings were installed along the eastern border of Lincoln Center and in the vicinity of monitoring well MW-11 between November 7 and December 4, 1996. The CPT logs generated from the CPT borings were used to identify permeable, saturated intervals within the A-zone aquifer. Groundwater samples were collected from selected intervals using the PIPP borings and analyzed for volatile organic compounds, including the Hazardous Substances, using EPA Method 8010. Data collected during these activities will be used to evaluate the subsurface lithology and the nature and extent of Hazardous Substances in the A-zone aquifer in the vicinity of the proposed Phase I IRA, and to design the A-zone aquifer test and the Phase I IRA.
