Maintaining this setup won't require any more compressed or liquid pure oxygen than maintaining any other spacecraft atmosphere, believe it or not. Oxygen concentrators available today are quite capable of producing a 30% oxygen atmosphere out an Earth-normal atmosphere purely by molecular sieve filtration. The various high-altitude oxygen enriched atmosphere facilities use oxygen concentrators rather than storing pure oxygen.

Edit: Although there will be places in the ventilation system with significantly higher oxygen fractions, where an oxygen concentrator outputs. Significantly less dangerous than compressed or liquid oxygen, but still a hazard.
