Explore updates on our MS4 program including 2024 accomplishments and the new 2025 theme!
2024 was a busy year! We completed 12 dry weather screenings, finished all township garage facility inspections, conducted monthly inspections of active commercial projects, and hosted multiple outreach events.
2025 marks the final year of our current five-year National Pollution Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permit term. We’ll submit our 2024 accomplishments in our Ohio Environmental Protection Agency (OEPA) annual report and apply for the 2026-2030 NPDES MS4 permit. With a new year comes a fresh start for our six Minimum Control Measures (MCMs) giving us the opportunity to tackle them all over again!
2025 also brings a new MS4 theme: Keep Dirt Where It Belongs. While this may seem like a simple concept, achieving it on an active construction site can be quite challenging. Erosion is a natural process, but construction activities can accelerate it. Although erosion cannot be entirely stopped, we can take steps to minimize its impacts and prevent man-made soil disturbance. One effective way to minimize erosion is by simply covering exposed soil. Planting native plants is ideal for erosion control as their deep roots anchor soil in place. Kentucky bluegrass is also commonly used in Ohio to stabilize a site after construction activities.
When colder months make seeding difficult, temporary stabilization techniques are crucial. The most common winter stabilization technique is mulching. Mulch not only covers bare soil, but it also promotes the germination of seeds in the growing season by holding moisture. This is why you often see straw thrown over grass seed! In Richland County, idle soil is to be temporarily or permanently stabilized after 14 days. Refer to the photo below for seasonal recommendations to stabilize soil effectively. For more details see Chapter 7 of the Rainwater and Land Development Manual. By implementing stabilization strategies, we can preserve soil integrity and support sustainable construction practices. Let’s keep dirt where it belongs!
There’s a lot in store for the 2025 MS4 program, so stay tuned and be sure to get involved! For more information keep an eye on our upcoming events!
