This is accomplished through site interviews, available historical data, regulatory agency interviews and file searches, and a physical inspection of the property. Hazardous substances refer to the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) substances, Resource Conservation and Recovery Act (RCRA) substances, and petroleum products. At a minimum, this Phase I ESA will consist of the following: 1. Compilation of the development history of the area, with an emphasis on chemical substances which may have been used or disposed of onsite and could have contributed to possible contamination. 2. A review of regulatory agency databases in order to determine potential environmental concerns relative to the site and adjacent sites within the specified search radii. 3. A physical inspection of the area to determine current site conditions and detect the potential for a release of hazardous substances. 4. Final report for the site that will include conclusions and recommendations, based upon the information obtained from the above referenced tasks. Data obtained during the Phase I ESA will be further utilized to assist in the development of the Phase II ESA scope of work. In concert with the Phase I ESA, Heartland will utilize a ground penetrating radar (GPR) at the site to survey and locate the known USTs and any additional suspected USTs or former UST excavation pits as well as potential hydraulic lifts. Ground penetrating radar is a geophysical technique that uses electromagnetic waves for willow subsurface reconnaissance and exploration. An electromagnetic impulse in the form of ultra -high frequency radio waves are emitted into the ground by a transmitting antenna, and the resulting reflection of transfer of waves from contamination plumes, boundary layers or buried objects is detected by a receiving antenna. The presence of buried objects or significant changes in conductivity of the layers will cause the electromagnetic wave to be reflected. Together these images provide direct information concerning subsurface conditions. These images will then be transposed onto a final map, documenting the locations of any anomalies, including USTs, in a GPR survey report, to be issued concurrently with the Phase I ESA report. 2.2 Underground Storage Tank Removal and Remediation Based on a review of the RFP, Heartland is providing the IBP with costs to remove two (2) 2,000-gallon and three (3) 3,000-gallon USTs from the site, along with the associated UST system implements and associated UST piping. Furthermore, costs are being provided to remove up to 1,500-gallons of petroleum liquid/sludge material, to over -excavate up to 1,500 tons of petroleum impacted soil from the UST excavation pit and to inject or otherwise introduce up to 1,000 pounds of Oxygen Releasing Compound (ORC) at the site. Before initiating sampling activities, Heartland will prepare a site work plan and a site -specific
