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 Requests Comments on Big Darby Water Quality Evaluation

Ohio EPA is accepting public comments until Sept. 29, 2017, on a draft report which summarizes findings from a 2014 survey of the biological, chemical and physical properties of the Big Darby watershed. 

In 2014, Ohio EPA sampled 28 streams in the Big Darby Creek watershed, which is one of the most biologically diverse stream systems in Ohio. The watershed drains approximately 555 square miles (355,200 acres) across six counties, including Champaign, Franklin, Logan, Madison, Pickaway and Union. Highlights in the draft report indicate substantial recovery from impairments documented during the 2001 survey in both Big Darby and Little Darby creeks. Among the beneficial use designations described in the report: 

Aquatic Life — All 34 locations evaluated on the Big Darby Creek mainstem and all but one of the 14 locations evaluated on Little Darby Creek were in full attainment of the existing aquatic life beneficial use designations. 

Human Health/Fish Consumption —The one meal per month PCB advisory in the lower reaches of Big Darby Creek for common carp was removed. However, a one meal per month mercury advisory was added for smallmouth bass in the Big Darby.

Public Water Supply — No streams in the 2014 study areas have public drinking water intakes, therefore, do not have a public water supply beneficial use designation. 

Recreation — Evaluation of E. coli bacteria results revealed that 26 of the 30 locations did not attain the designated Primary Contact Recreation use. Four locations, including three consecutive sites on the lower portion of Big Darby Creek, were in full attainment.

The draft report is available for review online: Also available online, the associated 2006 Total Maximum Daily Load (TMDL) report:

Written comments on the draft report may be submitted to Ohio EPA no later than 5 p.m. on Sept. 29 via email to, faxed to (614) 644-2745 or by mail to TMDL Program, Ohio EPA Division of Surface Water, P.O. Box 1049, Columbus, Ohio 43216-1049. For more information, contact Mike Gallaway at or (614) 728-3843.


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.
