I just did as you suggested.
Now in the log I get a
Variable "$q" will not stay shared at ...
error from the $q->param('deptLtr') in the subroutine.
When I read the mod_perl docs they suggest that use vars was one
approach to fix the "Variable X will not stay shared at" error.
What is the recommended approach? Pass a reference to $q?
Thanks

That makes $q a global. Bad, bad, very bad. Slap yourself on the wrist.
Remove that "use vars" line.

Now replace that with
my $q = CGI->new();

This is because Apache is using multiple processes to handle things.
Sometimes you're hitting a process for the first time, so it creates an
new CGI object and all is well. But sometimes your request goes back to
a process that has already loaded and executed this code before, so $q
is not a new CGI object.
