Sad to say but 30 days is not unusual in many towns.
The last two batches of permits I did took 5-6 weeks because I filed exemptions with them and they were not familiar with the new exemption forms so they let everything sit.
I had to make several polite calls to get them to finally call the SP to ask them what to do with the new forms.
It could be worse I hear of people waiting 6 months in towns with no local PD.
