The high value placed on clean air and water by local residents is reflected in local <br />commitments to plans and programs directed toward reducing air and water pollution <br />-24. The Eugene-Springfield metropolitan area has a strong potential for elevated levels of air <br />pollution due to the surrounding mountains, which provide a barrier to ventilation and <br />contribute to periodic episodes of stable atmospheric conditions, These conditions <br />effectively limit dilution and dispersion of air pollutants, resulting in the build-up of <br />concentrations near the ground. <br />-325. Some pollutants affecting metropolitan air and water quality originate outside the <br />metropolitan area. <br />426-Based on mor toring work performed by the Lyle Regional. Air Pollution Agency <br />LRAPA, the Latre Council of Government (LCOG) and LRAPA submitted <br />documentation demonstrating that the area meets the carbon monoxide standards since a <br />violation of the eight-hour standard has not occurred since 1980. In 1988, LRAPA and <br />LCOG formally requested redesi _ nation of the area as an attainment area for carbon <br />monoxide, The Oregon Department of Environmental Oiialjty (DEQ) forwarded the <br />reclassification request to the US. Environmental Protection Agency (EPA) Regional <br />Office in Seattle, In January 1994, EPA redesi nated.the Eugene- Springfield area to <br />attainment status for carbon monoxide. The area is cunxgptl in a 20- ear maintenance <br />period. Since redesignation there have been no violations of the carbon monoxide <br />standards. <br />LRAPA has developed a plan for meeting the new standards for fine particulates (the <br />PM10 standard). The LRAPA Board has approved the plan. The PM10 plan boumdary is <br />coterminous with Metro Plaii LJGB. A ma orit of the unpaved streets identified as high <br />priorities to address PM10 problems have now been paved. The PM10 plan approved by <br />the LRAPA Board concluded that no transportation-related control measures were <br />necessary_fo_r compliance with the P1vI10 Standard.
