1 5686 evidence indicates fine particulates have a greater potential for adverse effects on human health than do larger particulates. 6. The Eugene - Springfield Air Quality Maintenance Area Citizens' Advisory Committee for Total Suspended Particulates is scheduled to complete control strategies for attainment of the Oregon sus- pended particulate air quality standards by July, 1980. Local gov- ernments, in cooperation with state agencies, are conducting an analysis of the carbon monoxide problem in the metropolitan area. Preliminary results indicate that additional control strategies will be necessary if carbon monoxide air quality standards are going to be met by December, 1982 as required. Such strategies will be evaluated by July, 1980. 7. Reduction of open space, removal of vegetative cover, and develop- ment which increases the amount of impervious. surfaces (for example, paved streets', roofs, parking lots) contribute significantly to increases in the peak volume (quantity) of urban storm runoff entering storm sewers and natural drainage ways. 8. Water pollution in the metropolitan area results from both "point sources" (municipal and industrial wastewater discharg es) and "nonpoi nt sources" (pol l utants such as oil , dust and debris which are carried into streams by storm runof ) . Water pollution is most acute in streams which have low water flow conditions during the summer months (such streams include Amazon Creek and the "Q" Street ditch) 9. Offsettin g measures can. reduce the negative effects of _urban. level- . opment on water qual- i ty and quantity problems. Examples include on -site retention of storm water, inclusion of landscaped "buffer strips" adjacent to new developments and conservation and improve- ment of streams i de vegetaton along water, 'courses. 10. Total land designated and zoned for sand and gravel extraction in the metropol -i tan area and immediately adjacent subareas appears adequate for demand through' the planning period-. 11. Sand and gravel deposits are an important natural resource necessary for construction in the metropolitan area. Nevertheless, the extrac- tion of sand and gravel can conflict with other open space and values assoc i ated w * th water resources , vegetation .recreation , wildlife habitat and scenic quality. Proper rehabilitation and reuse of abandoned sand and gravel sites can result, however, in the return of valuable land for urban uses, including open space. 12. Due to the general nature of soils and mapping, site specific analysis is often necessary to determine the presence - of III -C-3
