The mitigation measure identified above would reduce the <br />potentially significant environmental impact described above to a less -than- <br />significant level by ensuring that existing building areas subject to demolition or <br />renovation are inspected prior to the demolition or renovation for the presence of <br />asbestos, PCBs, mercury, lead, or other hazardous materials. If hazardous <br />materials are found at levels that require special handling, the materials will be <br />managed in accordance with state and federal regulations and guidelines to <br />reduce any potential hazard. <br />The potential impact of the Project as contemplated in the Higher <br />Occupancy Scenario would be similar to the potential impact of the Project as <br />proposed, because the project - related demolition or renovation of the Project as <br />contemplated in the Higher Occupancy Scenario would be similar to the project - <br />related demolition or renovation of the Project as proposed. Likewise, the <br />mitigation measure would be similarly effective with respect to the Project as <br />proposed and the Project as contemplated in the Higher Occupancy Scenario. <br />B. Exposure to Contaminated Soil and /or Groundwater <br />Potential Impact: Under the proposed Project and the Higher <br />Occupancy Scenario, excavation and construction of proposed basement and <br />building foundations could expose construction personnel and the public to <br />existing contaminated soil and /or groundwater (Potentially Significant) <br />Mitigation: The following mitigation measure, as set forth in the <br />FEIR, is hereby adopted and will be implemented as provided in the Mitigation <br />Monitoring Program: <br />Mitigation Measure HM -2.1 <br />Finding: Mitigation Measure HM -2.1 is feasible and would reduce <br />the potentially significant environmental impact described above to a less -than- <br />significant level. <br />The mitigation measure identified above would reduce the <br />potentially significant environmental impact described above to a less -than- <br />significant level by establishing a Site Health and Safety Plan with policies and <br />procedures to protect workers and the public from potential hazards posed by <br />residual contamination issues at the site. <br />The population that would be present at or adjacent to the Project <br />site after construction would include workers employed at the site, patients and <br />visitors at the Medical Center, and off -site residents. In the future, potential health <br />effects could occur if any of these individuals were exposed to elevated levels of <br />contaminants in the soil or groundwater. Exposure could occur through inhalation <br />of soil and groundwater vapors that have migrated to the surface. Direct contact <br />
