Its tough to say. It seems to be a fairly popular fellowship in the past years with lots of applications and only a few awards. This year it says 55 awards, which isn't many. This year is weird for a number of reasons though...
1.) Its a weird time for a fellowship application cycle and atypical even for this one (which I think is generally a November one)
2.) It wasn't offered last year at all. So perhaps people don't know about it or assumed it went away? Based on discussion threads here doesn't seem to be as much activity or interest this year but again that is just speculation.
3.) Seems you have to pretty on top of it to be aware that its out there. I only found out because I had signed up for EPA notifications. If you aren't up on it, and you're busy you may well have missed it.
4.)Its been open only for a month and literally during the busiest time of year for graduate students trying to finish everything up, study for finals, make summer plans, etc.
Anyway seriously your guess is as good as mine. In 2013 looks like there was 1356 applications and only a little over 100 awards but I doubt that many people applied this go around for the above reasons.
I tend to speculate that probably not that many people applied this go around. Good luck and let me know when you hear anything.
