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.
