Abstract:
The Oregon Department of Transportation (ODOT) maintains and operates municipal

separate storm sewer systems (MS4s) throughout the state of Oregon for conveyance of

stormwater from ODOT owned facilities and properties. The Federal Clean Water Act

(CWA) requires that the discharge of pollutants to waters of the United States from any

point source, including MS4s, be effectively prohibited, unless the discharge is in

compliance with a National Pollutant Discharge Elimination System (NPDES) permit.

As part of ODOT’s NPDES MS4 Permit (No. 101822), ODOT is required to implement a

policy for conducting a stormwater treatment evaluation as part of the development

process for all new, redevelopment and restoration projects.

Furthermore, if an MS4 discharges to a Class V injection system as defined by the

Federal Underground Injection Control (UIC) program, such as a sump or drywell, the

Permittee is required to conduct water quality monitoring in accordance with the Oregon

UIC program regulated by the Oregon Department of Environmental Quality (OAR

Chapter 340, Division 44). Under the UIC program, monitoring is required to evaluate

the effectiveness of source control and treatment control best management practices

(BMPs) in eliminating contamination prior to stormwater injection into the subsurface.

This Stormwater BMP Monitoring Plan proposes an approach for monitoring the

effectiveness of stormwater BMPs constructed as part of an improvement project on

Highway 20 between 10th Street and Providence Drive in the City of Bend, Deschutes

County, Oregon. These stormwater BMPs were specifically designed to treat highway

runoff prior to discharging to underground injection controls (UICs).
