[See page 5-301 for the original comment] Construction-related emissions presented in Table 4.B-4 of the Draft EIR include diesel truck emissions associated with transport of soil assuming 2.6 million cubic yards of soil transported over a 5-year period to move earth from the eastern to the western portion of the site. Construction-related emissions presented in Table 4.B-5 of the Draft EIR include diesel truck emissions associated with soil transport assuming 1.13 million cubic yards of soil transported over a 5-year period to dispose of the remaining soils off-site from the eastern portion of the site, consistent with page 14 of the proposed Brisbane Baylands Infrastructure Plan. The overall amount of grading identified in discussed on Draft EIR page 3-71 includes grading activities associated with site remediation and landfill closure. However, it should be noted as stated on page 3-35 of the Draft EIR, that the specific methods to be employed to cap and close the landfill and for methane control are still to be finalized.
The air quality impacts of site grading and remediation are addressed in Section 4.b, Air Quality, of the Draft EIR, and are quantified in Tables 4.B-4 and 4.B-5, including emissions of both PM10 and PM2.5. The Draft EIR concludes on page 6-18 that cumulatively significant construction and operation emissions impacts will result from proposed Baylands development in combination with other past, present, and reasonably foreseeable future projects, and also concludes that the contribution of Baylands development to those cumulatively significant will be considerable. Mitigation Measures for air quality impacts include:
- Mitigation Measure 4.B-1. Construction requirements to reduce fugitive dust emissions dust emissions primarily during soil movement, grading, and demolition activities but also during vehicle and equipment movement on unpaved project sites.
