I just received this response from the email I sent yesterday!
"Your application submitted in response to the 2015 Fellowship Program has been received and assigned the above ID number. Please keep this notification for verification of submission. Review and evaluation will take approximately 6 months. You will be notified when a decision has been made on your application.
Most questions regarding your application can be answered by viewing the announcement at http://epa.gov/ncer/rfa/2015/2015_star_gradfellow.html. For questions not covered in the announcement, please submit your question to 2015FellowshipsRFA@epa.gov and someone will get back with you. Anticipated award timeline: We understand how important this funding is for you as you engage in your pursuit of a graduate degree. Unfortunately, due to delays receiving the Congressional Fiscal Year 2015 budget and internal process delays, the Fellowship award process and timeline was impacted. At this time, we anticipated 2015 Fellows to be selected and notified of their award recommendation by September and receive grant funding by late October."
Only a month off not too bad as long as there are no more delays..
