Seismic Valve Permit

Have a guy coming out tomorrow to install a seismic valve on my gas main - and just sent me an email about the city permit Fee. $215 for the permit, $120 "city management Fee".

The installation price of the valve is <$600.

a) Fairly normal permit fee, or silly as sh*t?

b) Would you pull the permit or just deal with it later if it ever comes up?
