o Discuss expected air quality impacts arising dur- ing the construction process. Develop mitigation measures such as dust wetting, parking concepts for construction workers, etc. o Discuss expected regional and local air quality impacts of future traffic (one scenario) in terms of federal and state air quality standards. Par- ticularly discuss implication for carbon monoxide, hydrocarbons, particulates (including lead) and nitrogen oxides. Conduct modelling as necessary. o Discuss the project in terms of consistency with the most recent Air Quality Plan. o Address all aspects of the air quality and provide documentation required by the Federal Aid Highway Program Manual (FHPM, 7-7-9) and the BAAQMD Guide- lines for Air Quality Impact Analysis of Projects. o Discuss air quality impacts to sensitive recep- tors. o Conduct early consultation liaison with Caltrans regarding air quality impacts of the project as required by the Clean Air Act Amendments and FHWA. o Develop air quality mitigation measures, if needed. Community Noise o Conduct noise measurements at up to 20 locations in the project area. Reduce to Leq dBA. Estimate peak hour Leq levels based upon traffic data (one scenario) supplied by the traffic analysis. o Project ultimate operating noise levels in terms of peak hour Leq. o Construct contour maps of noise for the present and one future year. Contours will be 5 dB incre- ments carried to a minimum of 55 dB. Future con- tour mapping will be conducted for one set of fu- ture traffic/geometric assumptions. o Discuss noise impacts to sensitive receptors, es- pecially existing residential uses. The noise analysis will be performed pursuant to Part 7-7-3 of the Federal Aid Highway Program Manual.
