G.13 SUB, EWEB, and Rainbow Water District, the water providers that currently control a water source, shall examine the need for a metropolitan-wide water master program, recognizing that a metropolitan-wide system will require establishing standards, as well as coordinated source and delivery systems. Services to Development Within the Urban Growth Boundary: Stormwater Findings 14. Historically, stormwater systems in Eugene and Springfield were designed primarily to control floods. The 1987 re-authorization of the federal Clean Water Act required, for the first time, local communities to reduce stormwater pollution within their municipal storm drainage systems. These requirements applied initially to the City of Eugene and subsequent amendments to the Act extended these requirements to Springfield and Lane County. 15. Administration and enforcement of the Clean Water Act stormwater provisions occur at the state level, through National Pollutant Discharge Elimination System (NPDES) permitting requirements. Applicable jurisdictions are required to obtain an NPDES stormwater permit from the Oregon Department of Environmental Quality (DEQ), and prepare a water quality plan outlining the Best Management Practices (BMPs) to be taken over a five-year permit period for reducing stormwater pollutants to "the maximum extent practicable." 16. Stormwater quality improvement facilities are most efficient and effective at intercepting and removing pollutants when they are close to the source of the pollutants and treat relatively small volumes of runoff. 17. The Clean Water Act requires states to assess the quality of their surface waters every three years, and to list those waters which do not meet adopted water quality standards. The Willamette River and other water bodies have been listed as not meeting the standards for temperature and bacteria. This will require the development of Total Maximum Daily Loads (TMDLs) for these pollutants, and an allocation to point and non-point sources. 18. The listing of Spring Chinook Salmon as a threatened species in the Upper Willamette River requires the application of Endangered Species Act (ESA) provisions to the salmon's habitat in the McKenzie and Willamette Rivers. The decline in the Chinook Salmon has been attributed to such factors as destruction of habitat through channelization and revetment of river banks, non-point source pollution, alterations of natural hydro graph by increased impervious surfaces in the basin, and degradation of natural functions of riparian lands due to removal or alteration of indigenous vegetation. 19. There are many advantages to keeping channels open, including, at a minimum, natural biofiltration of stormwater pollutants; greater ability to attenuate effects of Appendix Aa Page 7
