MFSA Columbia River
Not to get off topic but I came across this website 12 years ago. Maritime Fire and Safety Association operates on a VHF system.

Interesting reading, I have several spill response VHF channels spill response frequencies I can add once back to my radio guide at home. Believe me, you will hear them on VHF marine channels listed on the website when a HAZMAT situation occurs on a waterway or shipboard.
Their radio base is downtown Portland I think. -200 Market Merchants Building in Portland.
"In addition to the system itself, new channels (frequencies) were added at the same time. The Exchange now maintains constant watch over channels 11, 16, 18A and 5 separate tactical and command frequencies for oil spills and shipboard emergencies. They also have at their disposal channels 13, 80, and channel 14 which they set aside for phone patches from ship to shore or vice versa. Even with cellular phones becoming more commonplace the watch-standers at the Exchange, we find that 90% of communications with transiting ships on the Columbia River still come in by the more reliable VHF-FM radio."
