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. To report a spill or environmental emergency, contact the spill hotline (800) 282-9378 or (614) 224-0946. This number should only be used for emergencies. For all other calls, 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.


Ohio EPA Obtains Federal Approval to Remove Low RVP Fuel Requirements in the Cincinnati and Dayton Areas 

Ohio EPA has received approval from U.S. EPA to remove Ohio’s low Reid Vapor Pressure (RVP) fuel requirements in the Cincinnati and Dayton areas. 

Low RVP fuel became part of Ohio EPA’s air quality State Implementation Plan (SIP) a decade ago to reduce nitrogen oxides and volatile organic compounds emissions from vehicles and meet national ambient air quality standards for ozone. Low RVP fuel requirements are currently in effect in Butler, Clermont, Hamilton and Warren counties in the Cincinnati area, and Clark, Greene, Miami and Montgomery counties in the Dayton area. 

Ohio EPA proposed to remove the low RVP fuel requirements because they are no longer the cost-effective approach for reducing ozone that they were when the program was initiated to replace the E-Check program. 

The state has demonstrated to U.S. EPA that reduced emissions from MillerCoors Brewing in Cincinnati and Wright Patterson AFB in Dayton, which have recently completed environmentally beneficial projects converting from coal to natural gas, will more than offset the increased emissions of removing the low RVP fuel requirement. 

More information on the removal of the low RVP program is available online.


The Ohio Environmental Protection Agency was created in 1972 to consolidate efforts to protect and improve air quality, water quality and waste management in Ohio. Since then, air pollutants dropped by as much as 90 percent; large rivers meeting standards improved from 21 percent to 89 percent; and hundreds of polluting, open dumps were replaced with engineered landfills and an increased emphasis on waste reduction and recycling.
