The project would be conditioned such <br /> that the applicant would be required to perform a site-specific health risk <br /> assessment/air quality analysis focusing on pollution from 1-680, with any <br /> recommendations from the report to reduce health risks incorporated into <br /> the building plans for the project. As a result, the potential impact would be <br /> less than significant. <br /> c) The project is not anticipated to create objectionable odors affecting a <br /> substantial number of people. Therefore, this impact would be a less than <br /> significant. <br /> 5.4.
