• NPDES MS4 Program

    Under state and federal rules, the City of Oberlin is classified as a small Municipal Separate Storm Sewer System (MS4) community. This means that the city must manage its stormwater to comply with the MS4 permit, as issued by the Ohio EPA. Click here to learn about the Ohio EPA MS4 program.

  • What is stormwater?

    Stormwater comes from rainfall or snowmelt. Stormwater runoff is the rainfall or snowmelt that does not soak into (infiltrate) the ground due to impervious surfaces such as roofs, compacted lawns, streets, etc. Runoff can pick up pollutants such as sediment, oils, pesticides, etc. that then negatively affect water quality.

  • What is stormwater management?

    Stormwater is carried by curbs, open drainage ways, and storm sewers directly into the Plum Creek without treatment. Stormwater management seeks to reduce or slow the quantity of water carried into the creek during a storm or thaw, as well as improve the quality of the stormwater runoff.
