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 municipal 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. 
The most recent report, currently in draft form, covers the period of time from July 1, 2015 through June 30, 2016 and is called the Draft 2016 Annual Report. It is provided via a link to the right. 

Public Review and Comments
The City of Eugene invites the public to comment on the current Draft Year 2016 Annual Report. Comments received by 5:00 p.m., November 14, 2016 will be summarized in the final report to DEQ. Comments received after November 14, 2016 will be taken into consideration for potential future modifications to the City's stormwater program. 

Send written comments to NPDES Permit, Eugene Public Works, 99 East Broadway, Suite 400, Eugene, OR 97401. Send email comments to: therese.walch@ci.eugene.or.us.
 
Permit Renewal
The City's current NPDES permit, scheduled to expire December 29, 2015, has been administratively extended by DEQ until it acts on a new permit. In December 2015, the City submitted a permit renewal application package, including a proposed updated Stormwater Management Plan and draft Monitoring Plan. The permit renewal submittal is provided via a link to the right.

Thank you for your interest in Eugene's Stormwater permit and Stormwater program.
