As a precautionary response to COVID-19, Ohio EPA is currently operating with most staff working remotely. If you are working with our staff on a current project and you know the name of the employee you are working with, email them at firstname.lastname@epa.ohio.gov or call them directly. The Agency website has contact information for every district, division, and office. In order to reach us, please contact Ohio EPA’s main phone line at (614) 644-3020 or the main line for the division or office you are trying to reach.

After March 23, our district offices and Central Office will be temporarily closed and will have increasingly limited ability to receive deliveries, plans, etc. All entities are encouraged to submit plans, permit applications, etc., electronically where there are existing avenues to do so, such as the eBusiness Center (eBiz). Please refer to the list of available services on the main eBiz webpage. We encourage you to make use of all that apply, even if you have not used eBiz in the past. Plans under 25 MB can be emailed. For large plans over 25 MB, entities should work with the reviewer/division to upload via LiquidFiles. Directions for submitting docs via LiquidFiles is available on YouTube. We apologize for the inconvenience and thank you in advance for your understanding. If you wish to send hard copies of documents to any of Ohio EPA’s district offices, the best method to ensure we receive these documents is to send them via U.S. Mail. Since all offices are closed, deliveries outside of U.S. Mail (FedEx, UPS) will likely be returned because the offices are closed and deliveries cannot be made.

To report a spill or environmental emergency, contact the spill hotline (800) 282-9378 or (614) 224-0946

Multi-Watershed TMDL Projects

Text/HTML

In the past, Ohio EPA has addressed impairments at the project level. For example, if the Stillwater River basin was assessed, only impairments found in that study area would be addressed in the TMDL. However, as Ohio EPA has gone around the state and completed surveys in all of its watersheds, it has been found that many of these impairments are caused by similar sources. Being able to see these patterns of sources on a broader scale will allow us to put them into perspective and recommend reduction strategies. Covering multiple watersheds across the state will allow us to take a more wholistic approach to TMDL development and implementation and will make more efficient use of staff time and streamline TMDL development for the involved watersheds.

Although new to Ohio, the idea of addressing impairments through a multi-watershed approach has already been implemented by several states, like Kentucky and Michigan, for example. Ohio EPA is currently working on multi-watershed projects for the following impairments: bacteria, sediment, habitat, nutrients, and AMDAT. While the watersheds in these projects are from all over the state, the Agency has refrained from referring to them as “statewide” TMDLs because not all watersheds are covered under each project.

Multi-Watershed Bacteria Project

Ohio EPA uses the bacterium Escherichia coli (E. coli) as an indicator for the presence of pathogenic bacteria and viruses in a water body as a result of fecal contamination. Ohio EPA collects E. coli samples around the state every year during their water quality surveys. Common sources of E. coli include wastewater treatment plants, failing home sewage treatment systems/unsewered communities, combined sewer overflows/sanitary sewer overflows, illicit discharges, livestock waste, and improper application of biosolids.

Ohio EPA has learned from previous TMDLs that the same few sources of indicator bacteria are present in nearly every project area. Being able to see these patterns of sources on a broader scale will allow us to put them into perspective and recommend reduction strategies. Covering multiple watersheds across the state will allow us to take a more wholistic approach to TMDL development and implementation.

While we are grouping the TMDLs differently in this project, Ohio EPA is still using the same method to establish TMDLs for recreation use impairment. Taking a multi-watershed approach will allow for more efficient use of staff time and streamlines the TMDL development for these watersheds.
