6:27. Section I10 of the federal Clean Air Act reauires state and local air pollution control <br />agencies to adop_t_ federally approved control strategies to minimize air pollution. The <br />resulting body of regulations is known as a State Implementation Plan (SIP). SIPS <br />generally establish limits or work practice standards to miumize emissions of air <br />pollutants or their precursors. SIPS also include special control strategies for those areas <br />not meeting National Ambient Air_Quality_Standards (non-attainment areas). Most of the <br />regulations developed by LRAPA for controlling the emissions of air pollutants in Lane <br />County are included in the Oregon SIP. The original SIP was adopted inthe_ early 1 <br />in response to the 1970 federal Clean Air Act. It is amended periodically to respond to <br />current issues. <br />The 4ir Quality _11 aint" '`nee" 4'-ea Dill- cee taro" ^ o()FA--"1 stratGgie_, 1 r <br />0 <br />s{{s13 elm <br />ar^eu; was adapted fecal 1311 1 - ed i:a4 gwiemmei'{ -T-his ,40 ;4;4 Plan cuffent!y <br />°eis fbde •nl Clean Air A et '•°quiromem <br />quality standards, <br />-728. Reduction of open space, removal of vegetative cover, and development that increases the <br />amount of impervious surfaces (paved streets, roofs, parking lots) contribute significantly <br />to increases in the peak volume (quantity) of urban storm runoff entering stormwater <br />system and natural drainageways. <br />929. Water pollution in the metropolitan area results from both "point sources" (municipal and <br />industrial wastewater discharges) and "non-point sources" (pollutants such as oil, dust, <br />and debris which are carried into streams by storm runoff). Water pollution is most acute <br />in streams that have low water flow conditions during the summer months (such streams <br />include Amazon Creek and the "Q" Street ditch). <br />f 930_. Offsetting measures can reduce the negative effects of urban development on water <br />quality and quantity problems. Examples include on-site retention of stormwatcr, <br />inclusion of landscaped "buffer strips" adjacent to new developments and conservation <br />and improvement of streamside vegetation along water courses. <br />4-931. The Willamette and McKenzie Rivers run through many jurisdictions, necessitating <br />cooperative water management planning and consideration for downstream effects of <br />actions taken by a single jurisdiction. <br />32. The Eugene-Springfield area is currently in compliance with national standards for <br />carbon monoxide. The region will continue to be in compliance with the carbon <br />monoxide standard in the future. Vehicle fleet turnover and stricter emission controls on <br />newer vehicles are factors that will contribute to lower emissions in the future. <br />Policies <br />Exhibit B; Proposed amendments to Chapter IIr-C, Environmental Resources Element, Page 23 of 25 <br />of the Eugene-Springfield Metropolitan Plan (Metro Plan). <br />Laurel Ridge Record (Z 15-5) Page 300 <br />
