<br />7A <br />Page 45 <br /> <br />· .Describe Existing Conditions. Existing air quality conditions in Redwood City and the <br />Bay Area will be described. This section would include the following: <br />Description of the climate in Redwood City and the Bay Area <br />Discussion of all air pollutants regulated. at the federal and state levels and their <br />associated health effects (to include both PM10 and PM 2.5. among others) <br />Air quality standards <br />Description of toxic air contaminants <br />Description of the regulatory environment (EPA, CARB, and BAAQMD) <br />Air quality and toxic air contaminant levels in Redwood City and the Bay Area <br />Air quality attainment status <br />Future air quality planning efforts <br />Federal SIP requirements <br />state requirements <br />Clean air plans <br />Current General Plan <br /> <br />· Assess future air quality impacts. To assess future air quality impacts in Redwood <br />City under the proposed General Plan alternatives, the following tasks would be <br />conducted: <br />Compare General Plan build out projections of population and vehicle travel with <br />those available from ABAG and MTC. <br />Identify policies that implement current Bay Area 2005 Ozone Strategy (clean air <br />plan) transportation control measures. <br />Assess the plan for appropriate buffers between sources of air pollution <br />(including toxic air contaminants) or odors and sensitive receptors. This task <br />would include use of CARS recommended setbacks and screening level <br />modeling of diesel particulate matter emitted from vehicles on U.S. Highway 101, <br />EI Camino Real, and Woodside Road. <br /> <br />· Predict changes in airpoUution due to traffic. An assessment of changes to carbon <br />monoxide concentrations will be conducted. Roadside carbon monoxide concentrations <br />will be predicted using screening methods acceptable to the Bay Area Air Quality <br />Management District. These methods are based on the Caline4 Line-Source Dispersion <br />Model. The significance of the results will be based on a comparison with ambient air <br />quality standards. Emissions from the Port of Redwood City would be assessed <br />qualitatively. <br /> <br />· Assess construction impacts. An analysis of construction impacts will be based on the <br />potential for health and nuisance impacts and the level of dust control measures. <br />Typically, visible dust clouds that extend beyond construction areas and affect sensitive <br />land uses are an indication of significant air quality impacts due to construction. Use of <br />heavy-duty construction equipment near sensitive receptors could lead to unhealthy <br />exposure to diesel exhaust. These types of impacts would be evaluated on a qualitative <br />basis taking into account the amount of activity and the proximity of sensitive receptors. <br /> <br />· Identify mitigation measures. Reasonable and feasible mitigation measures to reduce <br />any significant air quality impacts would be identified and evaluated. These measures <br />would likely be orientated to reducing emissions from motor vehicles through trip <br />reduction and congestion management plans' (.e.g., implementation of applicable <br />transportation control measures). A list of reasonable and-feasible dust control measures <br />would be developed to reduce construction air quality impacts.
