[See page 5-176 for the original comment] The Draft EIR provides an analysis of the physical environmental impacts of proposed Baylands development by comparing existing (baseline) conditions to those that would occur with implementation of proposed development. The existing soils processing activities within the Baylands are being undertaken within the footprint of the former landfill. Proposed landfill closure, remediation, and grading activities, which will occur at the outset of Project Site development, will require cessation of the existing soils process activities. Thus, the air emissions impacts of existing soils processing activities will cease once the construction activities analyzed in the Draft EIR commence.
[See page 5-176 for the original comment] The referenced report by Dr. Fred Lee, Report on the Adequacy of the Investigation/Remediation of the Brisbane Baylands UPC Property Contamination Relative to Development of this Property, was reviewed and was found to contain no references to air pollutants, ingestion of toxics from construction disturbance, or phtyoremediation. That report is available as part of the proposed Baylands development public record at the Brisbane Community Development Department, 50 Park Place, Brisbane, California.
The Draft EIR contains a hazards assessment of construction-related hazards in Impact 4.G-2 on page 4.G-90 of Section 4.G, Hazards and Hazardous Materials. Project Site development and construction activities, including demolition and remediation activities, for all four scenarios will require disturbance of subsurface soils and groundwater. As discussed above, past land uses, including former Brisbane Landfill and Southern Pacific Railyard operations, resulted in soil and groundwater contamination at the former landfill, OU-1, and OU-2.
The analysis of this impact found that in addition to compliance with federal, state, and local regulations pertaining to the handling and disposal of hazardous waste, including preparation and implementation of a Soil and Groundwater Management Plan and a Master Deconstruction and Demolition Plan, hazards to the public through foreseeable upset or accident conditions involving the release of hazardous materials into the environment would be reduced to a less than significant level with implementation of Mitigation Measures 4.G-2a, 4.G-2b, 4.G-2c, 4.G-2d.
[See page 5-176 for the original comment] The first bullet under Mitigation Measure 4.B-1 on page 4.B-21 regarding fugitive dust is revised to read as follows:
Basic Controls that Apply to All Construction Sites
- All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas, and unpaved access roads) shall be watered as needed, but no less than two times per day on days with no precipitation.
