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

2012 Grand Lake St. Marys Alum Treatment Report Released

A federal report from U.S. EPA indicates the 2012 alum treatment reduced the internal phosphorus load in Grand Lake St. Marys by 55 percent.

“To no one’s surprise, the report revealed that a significant amount of phosphorus was inactivated as a result of the alum treatment, and we are satisfied with the results, but this was always one part of a multi-faceted, multi-year plan for the lake and for the watershed,” Ohio EPA Director Scott Nally said. “The alum treatment was a significant investment that had to be made to provide the time necessary to make sure we could implement the other comprehensive, long-term practices and plans we needed to have in place to be successful.”

Since 2011, the state has worked with the Grand Lake St. Marys Restoration Commission and the Lake Improvement Association to implement several new practices as part of a comprehensive, long-term plan to reduce the bioavailability of phosphorus in addition to the alum treatments. These practices include: dredging, rough fish removal, the installation of a phosphorus treatment train in a Grand Lake St. Marys tributary, lake leveling, aerators and the installation of littoral wetlands - all tools designed to reduce the effects of phosphorus in and around the lake. In addition, from a policy perspective, the state took significant steps to declare the Grand Lake Watershed a “watershed in distress,” completed a state nutrient management plan and implemented land management practices to also help manage the phosphorus issue in and around the lake.

The state will not apply a third alum treatment to Grand Lake St. Marys in 2013.

“We have accomplished a lot of work in the lake and in the watershed in the last two years, and we remain dedicated to the health and success of Grand Lake St. Marys,” said ODNR Director James Zehringer. “This problem wasn’t created overnight, and it won’t be fixed overnight either. The alum treatment was a single element in our overall plan to combat algae in GLSM, and we will continue to work within the watershed to improve the lake’s water quality.”

Through dredging in 2012, approximately 289,861 cubic yards of sediment was removed from Grand Lake St. Marys, which is more than was removed the past three years. ODNR’s Ohio State Parks and Division of Wildlife also removed more than seven tons of rough fish from Grand Lake St. Marys last year. An additional six tons were removed during a carp derby planned by the Lake Restoration Commission. Rough fish stir up sediment and contribute to phosphorus-related problems.


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. In the past 40 years, 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. Ohio EPA….40 years and moving forward.
