When would an ODP ever be specifically issued unless more than one procedure
was available and traffic separation depended on which one you flew? Is the
assignment of an ODP something that if they don't specifically issue it as
part of your IFR clearance, then you can't fly it?

We have a vector SID here that was created because there are some TV
antennas less than 3 miles SE of the airport that are about 700 feet
above airport elevation. Every IFR aircraft gets the SID even though if
you depart to the west you don't have to have it. If you file NO SID
your take off instructions will be "leaving 4500 fly runway heading(or
some other heading that works for me)." The airport elevation is 3650.


The way it works in my airspace is that I issue you an IFR departure
clearance *after* I deconflict you from other IFR traffic. You fly any
pertinent ODP at your discretion unless I assign something else. You do an
ODP and get with traffic, and I am the guy who screwed up.

The difference at a tower is I can issue you a heading and that vector
will separate you from other traffic.
