Class D's have little protection. I live smack dab in the middle of where the two signals will be and I couldn't tell you the last time I've received WCNM. 103.9 previously had WUEY-LP licensed to New Brunswick from the same tower WOLD-LP will be on from 2015-17 so it's already happened too.
The upside is Class D non commercial education FM stations (not translators) dont have to maintain public files... hallelujah!
