MS4 Documents Library

In Oak Lodge, storm water runs directly into local ditches, creeks and rivers without treatment. The MS4 Permit supports water quality efforts.

MS4 stands for "Municipal Separate Storm Sewer System", and is a regulatory permit required by the Oregon Department of Environmental Quality (DEQ) under the National Discharge Elimination System (NPDES). OLWS partners with Clackamas County and 11 co-permittees to implement the Phase i MS4 Permit in our area. Oregon DEQ bases the requirements in part on the Water Quality Status and Trends Analysis. The permit requires human efforts to keep pollution out of waters of the state.

The current MS4 Permit is posted here.

The MS4 Permit requires the creation of a Stormwater Management Plan (SWMP) with activities designed to reduce pollutants in storm water runoff.

The current Stormwater Management Plan (SWMP) is posted here.
