The Bay Area Air Quality Management District(BAAQMD)Bay Area 1991, 1994, 1997,and 2000 Clean Air Plan contain district-wide control measures to reduce carbon monoxide and ozone precursor emissions. The proposed demolition and construction activities at the Multi-Agency Maritime Facility would not generate additional,long term,permanent carbon monoxide or ozone sources and therefore, would not conflict or obstruct the implementation of the BAAQMD Clean Air Plan. The BAAQMD defines exposure of sensitive receptors to toxic air contaminants and risk of accidental releases of acutely hazardous materials(AHMs)as potential adverse environmental impacts.Examples of sensitive receptors include schools,hospitals,and residential areas with children,and convalescent facilities.None of these sensitive receptors occur near the project site. Since the proposed construction activity would be localized to the area of the existing abutment,pier,gangway and floating dock system at the Multi-Agency Maritime Facility,there would be no air quality impacts to sensitive receptors.There would also be no anticipated storage of AHMs on the project site;therefore,the project would not result in any additional air quality impacts to sensitive receptors. e) The BAAQMD defines public exposure to offensive odors as a potentially significant impact.Potential odor impacts are based on a list of specific types of facilities, such as wastewater treatment plants, landfills,refineries,etc.The temporary short-term and localized,small area disturbance of channel sediments resulting from the removal of existing concrete guide piles could result in odors.These bottom sediments may contain byproducts of anaerobic bacterial decomposition,including sulfur compounds. The organic fraction of the sediments is relatively small and no large-scale odor emissions are anticipated. Small,insignificant quantities of odors would be localized at site of the 8 existing piles that would be removed. Any odors that occur should dissipate quickly in the surrounding area. The duration and extent of these potential odors would be short-termed and limited.
