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 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

Helping communities and businesses access compliance, technical and financial assistance for their environmental needs.

Ohio EPA recognized YSI, Inc., in Yellow Springs in September 2018 with a Platinum Level award for its sustainability initiatives, conservation and efficiency programs, and water quality education efforts. YSI manufactures sampling and monitoring instruments for environmental and in-process monitoring, including equipment widely used to track water quality conditions and trends.

YSI’s sustainability efforts and achievements include:

  • Implementing conservation and efficiency programs at its Yellow Springs facility.
  • Eliminating the use of nickel-cadmium batteries and transitioning from alkaline batteries to lithium-ion batteries in water monitoring instruments to protect water quality.
  • Beginning a take-back program for its equipment where instruments are repaired to extend their lifecycle. Instruments that can’t be repaired are recycled, along with other solid waste, resulting in about 1,000 pounds of materials diverted from landfills each month.
  • Switching to LED lighting and improving the HVAC system that is expected to produce at least a 55 percent reduction in electricity use.
  • Reducing water consumption and natural gas use.
  • Encouraging YSI employee participation in the Dayton Children’s Water Festival and partnering with organizations such as the Little Miami River Kleeners and the Tecumseh Land Trust.
  • Supporting employees’ efforts to educate people locally and beyond, about water quality and protection of water resources.
