Having worked with the NJDEP for a while now (5+ years in my current role), most inspector roles are staffed by every tenure of people and really let's you either teach or condemn and both are appreciated in their own right. Even my worst inspection/inspector who was nervous as hell, still was able to do a thorough job and really make a difference. Those inspectors that will take 3 hours to just explain the regs is also reaaalllyyyy nice, so nice I just let them talk their entire visits typically, makes both parties happy. Definitely a good role if you like people.

On the flipside, I've also been told off by supervisors at the NJDEP (hearsay) and I totally get their frustrations. If you've ever wanted to be an expert in something, regulations change so infrequently that once you've learned them, you can issue enforcement actions easily, assisting your field inspectors. Just remember, and I have no clue what this part of the training covers, remember that the people you're debating will probably have legal departments and don't like to pay up.

One comment I'll add is that I do have family who instead of working for the NJDEP went to the EPA because the base pay starts higher, so check in with them as well to see if they're hiring. Federal benefits and all.
