Let's set up a call to discuss if you don't mind. Does Monday work for you?

I hope you both made it back home safely. We appreciate you and Administrator Pruitt taking the time out of your very hectic schedules to visit a site that is important to Alcoa and its continued operation in the state. As we briefly discussed, we are interested in talking further with you about EPA Region V's intent to classify Warrick County as non-attainment for S02, based on an outdated Sierra Club model. We understand they intend to send the 120-day letter to Governor Holcomb by Aug. 14, notifying the State of EPA's intent to modify the attainment status recommended by Indiana's Dept, of Environmental Management. We are happy to have our environmental team share with EPA why we believe our model, based on real data, is more accurate and reflective of what S02 emissions we can expect from our aluminum smelter operation. I would appreciate your guidance on how we can best move forward to find a reasonable solution. I will be in DC the week of Aug. 14, and happy to schedule a meeting to discuss. Thanks again for your visit to the mine, and your offer of support. All the best, Sonya 17cv1906 Sierra Club v.
