Response to Draft Environmental Impact Report February 7, 2019 Harbor View Development Project, Redwood City CA Page 5 of 7 would subject children to unhealthy and potentially harmful air. Furthermore, as discussed in the sections below (and in various sections of the DEIR), the use of an adult soccer field is not an appropriate use of the Site. The DEIR (ESA 2019) expressly states the following: "In the BAAQMD's health risk database, the Graniterock manufacturing plant located immediately adjacent to the east side of the Specific Plan Area shows an annual average PM2.e concentration of 206 micrograms per cubic meter. This level represents a potential health risk tosensitive receptors in the vicinity of this facility." "For the purposes of this air quality analysis, sensitive receptors are places with people who are considered to be more sensitive than others to air pollutants. As introduced above (see 'Toxic Air Contaminants" and "Existing Air Quality"), the reasons for greater - than -average sensitivity include pre-existing health problems, proximity to emissions sources, or duration of exposure to air pollutants. Schools, hospitals, and convalescent homes are considered to be sensitive to poor air quality because children, elderly people, and the infirm are more susceptible to respiratory distress and other air quality -related health problems than the general public. Residential areas are considered sensitive to poor air quality because people usually stay home for extended periods of time, with associated greater exposure to ambient air quality. Recreational uses are also considered sensitive due to the greater exposure to ambient air quality conditions because vigorous exercise associated with some forms of recreation places a high demand on the human respiratory system. Adoption and development under the Specific Plan would be required to implement any project -specific recommendations to reduce the potential health risk." 'Toxic Air Contaminants (TACs) are a broad class of compounds known to cause morbidity or mortality (usually because they cause cancer or serious illness) and include, but are not limited to, the criteria air pollutants listed above. Specifically, TACs include diesel particulate matter (DPM) (discussed below) emitted by diesel engines, and benzene and CO emitted by gasoline engines. Air pollution sources located near sensitive receptors are known to pose health risks. Sensitive receptors typically include land uses where individuals are susceptible to health risks when exposed to air pollution, including residences, day cares facilities, schools, medical facilities, and parks and recreational facilities . TACs are typically emitted by on- and off-road motor vehicles, stationary emission sources, and by industrial and commercial manufacturing. The California Office of Environmental Health Hazard Assessment (OEHHA) has identified several TACs that pose short-term (acute health risk), long-term (chronic risk), and/or carcinogenic health risks." 'The primary sources of TACs identified within 1,000 feet of the Project site include the exhaust from diesel engines trucks in the area, and concentrations of DPM are higher Project No.: 102-102-100 PATH ORWARD
