 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

Ohio’s public water systems (PWSs) provide an invaluable service and vital resource to the populations they serve. Chapter 6109 of the Ohio Revised Code authorizes Ohio EPA to safeguard public health by enforcing requirements of the Safe Drinking Water Act. The Division of Drinking and Ground Waters (DDAGW) oversees the operation and permitting of PWSs, which partially includes the review of engineering plans.

To ensure that adequate quantities of safe drinking water are provided, DDAGW staff review engineering plans and other information pertinent to proposed PWS projects. The division also develops engineering guidance documents, collaborates with the Ohio Section of American Water Works Association and reviews PWS backflow prevention and cross-connection control programs.

For more information or questions about engineering considerations for PWSs, please contact your DDAGW district office or call DDAGW Central Office at (614) 644-2752.

IMPORTANT – Plan Submittal Instructions

Due to the restrictions from COVID 19, hard copy detail or general plans will not be received by Ohio EPA. When plans are received electronically, an invoice for payment of the review fee, along with instructions on how to pay, will be sent to the party that submitted the plans. Review will begin when payment is received. The detail plans, general plan, Water Supply Data Sheet and/or specifications can be submitted to DDAGW.Engineering@epa.ohio.gov either directly if less than 25 MB or through Liquid Files. If sending plans through Liquid Files you will be asked to provide an email address for an Ohio EPA staff person, please use susan.schell@epa.ohio.gov. Directions for submitting docs via LiquidFiles is available on YouTube. If you currently have plans submitted, you can use the DDAGW.Engineering@epa.ohio.gov to inquire on the status or email the staff engineer directly who is reviewing them. If you are submitting a revised set of plans in response to comments, then please direct them to the staff person who signed the comment letter. If a fee is outstanding, the Agency will reach out to obtain it.  If you need to submit a plan package via liquid files, please visit https://fileshare.epa.ohio.gov/message/new.
