Per Surly, the fat tire operating pressure is 5-15 psi. I honestly never go over 15 psi since my pressure gauge is limited to 15 psi. My basic pressures are:

Summer, dry riding - 10-12 psi (including some road riding getting to and from the trails)
Winter rider, pack snow - 8-10 psi
Winter riding, fresh/soft snow - 5-6 psi (very soft snow, I've been down to ~4 psi)

I'm sure you can ride higher pressures than I have listed, but IMHO you are removing the fat tire advantage.
