Elizabeth Toot-Levy to Present on the Development and Potential Impact of Ohio's First Far-field TMDL at the One Water Technical Conference

Elizabeth Toot-Levy a Project Scientist (Ohio) will present "The Maumee Watershed Nutrient Total Maximum Daily Load (TMDL) – What's Next for the Western Lake Erie Basin (WLEB)" at the One Water Technical Conference on Thursday, July 28th in Cleveland, Ohio.    

Adrienne Nemura a Principal Water Resources Engineer (Ohio) will be attending the conference. 

Elizabeth and Adrienne will be available to meet with attendees to answer questions about the presentation or Geosyntec's services. Geosyntec works with clients to help find affordable ways to comply with the Clean Water Act by establishing a regulatory strategy, using science and engineering to quantify benefits, and conducting effective permit and enforcement negotiations for wastewater and stormwater.

Presentation Information

Title: The Maumee Watershed Nutrient Total Maximum Daily Load (TMDL) – What's Next for the Western Lake Erie Basin (WLEB)
Presenter: Elizabeth Toot-Levy
Date: Thursday, July 28th
Time: 12:00 p.m. – 12:45 p.m.
The presentation will evaluate the development of Ohio's first far-field TMDL and its potential impact on point sources, through the preliminary modeling report step in the process.  We will look at point source loads as detailed in the modeling, proposed wasteload allocations included in the TMDL calculations, and evaluate potential flexibilities to be incorporated as part of the point source implementation aspects of the TMDL. Given that the majority of the phosphorus load to the WLEB is attributable to non-point sources, we will also evaluate the loading allocations included in the TMDL calculations and any information available at that time regarding the associated reasonable assurance necessary for US EPA approval of the TMDL.
