Thanks for writing in. Your work for the EPA can definitely help differentiate you , both in terms of your promotional path so far as well as just coming from a government/environment perspective.
As for your school choice, Yale is probably a reach with your current GMAT, Cornell/UNC are good near-reach options , and the others you should be competitive at. Babson has a strong entrepreneurship theme so you may want to call out how your long-term goal fits into that strength of the school. You seem to have a good grasp on what your strengths are and how to position yourself – so the one other piece I can offer is to substantial research on these schools and make sure you position yourself specifically to what each school can offer you.
Best of luck,
