9. ENVIRONMENTAL REPORT operation hours and increased noise and emissions and potential violations of air quality permit conditions. 9.3.5 Energy Management and Consumption System Alternative 1 would result in impacts to energy consumption. Impacts from System Altemative 1 would be less than impacts from System Alternatives 5 and 4. However, it is anticipated that energy consumption at MWMC facilities will still increase under System Alternative 1. Energy consumption is tied to volume of treated material processed throughout the MWMC system. Flows and loadings processed through the facility are, in turn, driven by various factors including population and industrial growth, seasonal precipitation, and equipment efficiencies. As noted above, replacement of equipment during normal maintenance procedures would likely incorporate new technology. The corresponding equipment efficiencies would reduce energy demand. However, even with increased equipment efficiencies, anticipated increases in flows and loadings would likely result in energy demands that exceed current levels. 9.3.6 Floodplains and Soils System Alternative I will have no anticipated impact on the floodplain because no changes will be made that affect flow in the river channel. Construction activities would not occur and there would be no disturbance of surface soils at MWMC facilities. 9.3.7 Land Use and Zoning System Alternative 1 would avoid land use and zoning impacts. Because the MWMC facilities would remain in their current configuration, potential impacts related to land use compatibility would not occur. System Alternative 1 could result in secondary (indirect) land use and zoning impacts. To reduce wastewater flows, the cities of Eugene and Springfield could consider zoning changes and building moratoriums as a method to constrain population and industrial growth in the metropolitan area. Under this scenario, impacts associated with land use and zoning could be greater than System Alternatives 5 and 4. In addition, violations of permit requirements tied to growth in flow and loadings to the treatment facilities could result in enforcement actions by the State, including moratoriums on future development and hookups to the sanitary collection system until the problems are resolved. 9.3.8 Transportation System Altemative 1 would avoid impacts to transportation/circulation in the vicinity of MWMC facilities. This altemative would not contribute to short-term construction-related impacts resulting from additional truck and construction vehicle traffic. This alternative also would not result in vehicular increases on the surrounding street system. Impacts associated with transportation/circulation would be less than impacts associated with System Alternatives 5 and 4. MWMC_9.0_REV14.DOC 9-7
