NPDES Municipal Stormwater Permit

NPDES Municipal Stormwater Permit


The City of Eugene holds a permit under the federal Clean Water Act for the stormwater discharged from the public stormwater system into the Willamette River and 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 public system to the maximum extent practicable. The permit requires implementation of a set of best management practices comprising the City's Stormwater Management Plan (SWMP), water quality monitoring, and regular reporting. The  Department of Environmental Quality (DEQ) administers federal NPDES permits for municipalities and other local agencies in Oregon. 

Annual Reporting


Each year, the City 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 implementation of best management practices and water quality trends. Recent years' reports (2014 - 2019) are provided via links to the right, along with other stormwater permit program related documents and information.
  
Public Comments
The City welcomes public comment on the stormwater program and annual reports anytime. Comments will be taken into consideration for potential future program modifications. Thank you for your interest!
