Yeah that would explain it...the code is only in the script for lines. 
Reading the original NHD data dictionary, 34306 is legal for points, 
lines and areas.

Re: same rules for all areas and lines - the rule set has to be broken 
down by line vs. point vs area...in theory you'd want to be sure that 
the resulting OSM tag makes sense for the resulting OSM node type, but 
other than that, there may be several cases where the codes could apply 
to multiple geometry types.

cheers
