EXHIBITS Page 98 <br />Policies <br />C.22 Design of new street, highway, and transit facilities shall consider noise mitigation <br />measures where appropriate. <br />C.23 Design and construction of new noise-sensitive development in the vicinity of existing <br />and future streets and highways with potential to exceed general highway noise levels <br />shall include consideration of mitigating measures, such as acoustical building <br />modifications, noise barriers, and acoustical site planning. The application of these <br />mitigating measures must be balanced with other design considerations and housing <br />costs. <br />C.24 Local governments shall continue to monitor, to plan for, and to enforce applicable noise <br />standards and shall cooperate in meeting applicable federal and state noise standards. <br />Air, Water and Land Resources Quality (Goal 6) <br />Findings <br />23. 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 />25. Some pollutants affecting metropolitan air and water quality originate outside the <br />metropolitan area. <br />26. Based on monitoring work performed by the Lane Regional Air Pollution Agency <br />(LRAPA), the Lane 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 redesignation of the area as an attainment area for carbon <br />monoxide. The Oregon Department of Environmental Quality (DEQ) forwarded the <br />reclassification request to the U.S. Environmental Protection Agency (EPA) Regional <br />Office in Seattle. In January 1994, EPA redesignated the Eugene-Springfield area to <br />attainment status for carbon monoxide. The area is currently in a 20-year 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 boundary is <br />Laurel Ridge Record (Z 15-5) Page 661 <br />
