<br />Why are these missing from Costco's EIR.? My conclusions are because of these <br />descriptions: <br /> <br />Ozone: .. Ground-level ozone is the principal component of smog. Ozone is not directly <br />emitted into the atmosphere, but instead forms through a photochemical reaction of <br />reactive organic gases and nitrogen oxides... Motor vehicles create the majority of <br />reactive organic gas and nitrogep oxide emissions in the South Bay region." <br /> <br />Carbon Monoxidl: <<... non-reactive pollutant that is highly toxic, invisible, and <br />odorless... The largest sources of CO emissions are motor vehicles. wood stoves and <br />fireplaces. Unlike ozone, CO is directly emitted to the atmosphere." The effects on <br />people are describ~. <br /> <br />Nitrogen Dioxide: ..... essential ingredient in the formation of ground-level ozone <br />pollution. .. emitted from high-temperature combustion processes, such as those <br />occurring in trucks. cars and power plants. Home heaters and gas stoves also produce <br />Nfu in indoor settings. .. capable of damaging cells lining in the respiratory tract... .may <br />worsen the effect of allergens in allergic asthmatics, especially in children. .." <br /> <br />Sulfur Dioxide: .....colorless gas with a pungent, irritating odor. Its major sources are <br />diesel vehicle exhaust..," <br /> <br />Particulate Matter: "These particles vary greatly in shape, size. and chemical <br />composition, and can be made up of many different materials such as metals, (including <br />lead), soot, soil and dust.., fine particulates come from smoke, dust, aerosols, and <br />metallic oxides. Although. particulates are found naturally in the air, most particulate <br />matter found in the Bay Area are emitted either directly or indirectly by IDQ:tQr <br />yehicles... ." <br /> <br />Toxic Air Contaminates (TAC): "broad class of compounds known to cause morbidity <br />or mortality (usually because they cause cancer or serious illness) and include, but are not <br />limited to, the criteria air pollutants listedabove....caused by industry, agriculture, fuel <br />combustion. and conunercial operations (e.g., dry cleaners)..." <br /> <br />Diesel Exhaust: "... predominant T AC in urban air, with the potential to cause cancer. It <br />is estimated to represent about two-thirds of the cancer risk from T ACs (based on a state <br />wide average). <br /> <br />12.1.5 Existing Pollutant Sources and Sensitive R.eceptors in the Precise Plan Area. says: <br />"The largest sources of pollutants witbin the Precise Plan area are vehicles on the local <br />roadway network." It then defines the sensitive receptbrsmost likely to be affected by air <br />pollution as "children under 14. the elderly (over 651 athletes. and peot;tle with <br />cardiovascular and chronic respiratory diseases," <br /> <br />7A <br />Page 69 <br /> <br />J <br /> <br />2 <br />
