NPDES Municipal Stormwater Permit
NPDES Municipal Stormwater Permit
The City of Eugene holds a permit under the federal Clean Water Act for the municipal stormwater it discharges directly into the Willamette River and indirectly into the Willamette River through other local waterways, including Amazon Creek. The permit, formally called the Phase I National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permit, requires that the city reduce the discharge of pollutants from the municipal stormwater system to the maximum extent practicable, and includes monitoring and reporting requirements, as well as a set of best management practices that define the city's Stormwater Management Plan (SWMP). The Oregon Department of Environmental Quality (DEQ) administers federal NPDES permits for municipalities and other local agencies in the state. 

Annual Reporting
Each year, the City of Eugene prepares a Stormwater Annual Report in accordance with the requirements of its NPDES permit. The Annual Report provides information on the progress of stormwater program activities during the reporting period including: program management, implementation of best management practices, and water quality monitoring.
 
The current report, for Year 2014 covers the period of time from July 1, 2013 through June 30, 2014 which also coincides with the City's fiscal year 2014. The Year 2014 report and previous reports to Year 2011 are provided on this web page (see links to the right). Reports for Year 2010 and prior to that are available upon request.
 
Comments
Each year in October/November the City invites the public to review and comment on the draft Stormwater Annual Report. Comments are taken into consideration for potential future modifications to the City's stormwater program, and are summarized in the City's report to DEQ.
