<br />the no-build and base year results in order to determine the consistency of each alternative with . <br />the applicable portions of the SIP. <br /> <br />4.5.3.2 <br /> <br />NoiselVibration Impact Analysis <br /> <br />The noise and vibration analysis, including train whistle blowing, will indicate the magnitude and <br />extent to which sensitive receptors in the vicinity of the alignment will experience changes in <br />noise and vibration levels during the construction and operation of the project. Review maps and <br />aerial photographs that show land uses within 152.4 m (500 ft.) of the project limits will be used <br />to identify such sites. Project limits include the alternatives or combinations of alternatives and <br />other roads and streets with increased traffic fromtraffic diversion. Noise-sensitive-Iand uses In <br />the study area will be identified by land uses that fall into FHW A categories A to E and FT A <br />categories I to 3: schools, churches, residences, parks and recreational space, libraries, hospitals, <br />and rehabilitation centers. Vibration-sensitive structures will include historic structures, hospital <br />surgical wards, and structures housing sensitive equipment or processes. Existing rail and traffic <br />data (speeds, volumes, vehicle classification) will be reviewed with respect to noise and vibration <br />emISSIOns. <br /> <br />4.5.3.3 <br /> <br />Contamination Impact Analysis <br /> <br />A Contamination Screening Evaluation Report (CSER) for the selected Commuter Rail alignment <br />will be prepared by the Contractor in accordance with the procedures outlined in NEP A. <br />Potential hazardous materials and petroleum contamination sites will be identified based on a <br />review of public records and field inspections. Sites identified will be ranked in accordance with - . <br />potential contamination impacts. Recommendations will be developed for further Preliminary <br />Contamination Assessments (PCA) for any sites ranked as medium or high-risk contamination <br />sites. <br /> <br />4.5.3.4 <br /> <br />Water Quality Impact Analysis <br /> <br />The Contractor will conduct a Water Quality Impact Evaluation (WQIE) for the proposed project. <br />The objective of the study will be to identify and document water quality issues relating to <br />compliance with the Clean Water Act, other federal and state regulations. <br /> <br />4.5.3.5 <br /> <br />Energy Impact Analysis <br /> <br />The Contractor will analyze the energy implications of the alternatives considered. Baseline <br />condition energy consumption conditions will be evaluated with reference to existing sources of <br />electric and petroleum power in the study area. Current fuel consumption by transit mode will be <br />calculated using operating data. Automobile energy consumption will be estimated using data on <br />automobile vehicle miles traveled. ' <br /> <br />4.5.3.6 <br /> <br />Traffic Impact Assessment <br /> <br />The traffic analysis at the commuter rail stations will include an analysis of the street network in <br />the immediate vicinity of the proposed stations. The following analysis will be performed: <br /> <br />· The trip generation for each station will be determined based on the park-and-ride capacity, <br />estimation of transit trips, and the type and intensity of adjacent land uses. The trip <br />generation will be estimated for both no-build and build conditions. <br /> <br />. <br /> <br />Work Program for Northstar Corridor MIS and EIS <br />For the Proposed Commuter Rail Service <br />February 25, 1999 <br /> <br />~- <br />-' <br /> <br />16 <br />Work Program <br />
