Politics play a major part in the runway lenght game in Norway. Many regional airports are bulit in rocky terrain, and there is often no level ground beyond the concrete. There is massive pressure on the CAA to make excemptions from rules regarding RESA for many regional aiports, because of the massive cost of improvement.
(I can think of several with similar layout, massive drops close to the runway.
We have allmost 3km of concrete at Bardufoss, but if you go past the over run area on RWY10 you are a dead man.)
In my humble opinion this was only a matter of time, we have had many rwy excursions in Norway in the past. Many of the STOL aerodromes, but on larger ones as well.
Hope this will put the last nail in the "we don't need to comply with international standar because it's a small airport" coffin.
