The EIS will include a <br /> quantitative noise analysis that provides sufficient detail to determine impacts and the need for <br /> mitigation measures. A general vibration assessment will be conducted that incorporates geologic data, <br /> architectural components of vibration sensitive receptors and LRT vehicle and track data. If vibration <br /> impacts are anticipated, a detailed vibration analysis would then be conducted to determine the need <br /> for mitigation measures. <br /> The following steps are required for the noise and vibration analysis: <br /> Identify noise and vibration sensitive receptors <br /> Measure existing noise levels <br /> Develop General Noise Assessment Model <br /> Develop Detailed Nose Assessment Model <br /> Collect General Vibration data inputs <br /> Develop General Vibration Assessment Model <br /> Noise &Vibration QA/QC ITR (Acoustical Eng) <br /> Prepares Draft and Final Noise and Vibration Technical Memorandum Report/Comments <br /> Deliverables: <br /> Noise and Vibration Technical Memorandum, in accordance with the FTA 1995 guidance,Transit <br /> Noise and Vibration Impact Assessment (Draft and Final). <br /> DEIS Chapter on Noise and Vibration (Draft and Final). <br /> 4.4.1,6 I iazardous and Contary-flnatted IMaterWs <br /> This task will describe the potential for discovering contamination/hazardous materials in the Durham- <br /> Orange LRT Corridor and subsequent documentation in the EIS. For the LPA and alignment options, at a <br /> minimum, the URS team will: <br /> Identify Attempt to identify the presence of any known hazardous waste or contamination <br /> within areas to be affected by potential construction. <br /> For property to be acquired, assess the presence of environmental problems or contamination <br /> due to past or current practices or land use. <br /> List activities of other industries/commercial areas in the immediate area(s). <br /> Conduct searches of known contaminated sites adjacent to or on route of proposed project <br /> facility. <br /> Identify sites requiring further analysis. <br /> The URS team will identify properties along and adjacent to the potential project corridors where <br /> contamination may have been caused by past management, use, storage or disposal of hazardous <br /> materials. Identification of sites that may have hazardous soils will be completed using available records, <br /> Dunrhaii,°i...Orange III ight Rail 111,,.rainsit Project I June 201.3 X4.1. ' DlRAFIll' <br />
