Which EQ are you using? The Waves RenEQ does this alot, many others don't do it quite as much.
It's to do with the narrow Q, I suspect. Most EQ's tends to boost a tad bit on the freq's around a cut - that is if you're doing a cut at 210 hz, you'll get a slight boost in the 210-230 hz area. There's an expression for it but I can't seem to remember it.
Edit: I just did an example in Logic with a relatively narrow Q. Had I narrowed the Q even more, the boost would've increased. Picture is attached.
Edit again: And yes, even on a 32-bit float system, there's no reason to go into the red if it's avoidable. When I mix, I usually have my mix peak at -6 dB so the Mastering Engineer has room for working. If I need to show roughs to clients, I just boost up against 0,0 dB on the SSL BusComp I have on my 2bus when mixing and put on a Waves L2 limiter that attentuates 1-3 dB on peaks.
