Here is the entire chart, as well as the RNAV Rwy 36 that illustrates the terrain issues associated with Runway 36. When a note is attached to minimums, it becomes a conditional part of the minimums. If the PAPI for 36 is inoperative you cannot circle to Runway 36 from any of the IAPs for Runway 18 (there are also 3 RNAV IAPs to Rwy 18, all with the same conditional note.) No matter whether Ops Specs are involved, or not; this note applies to everyone when the Runway 36 PAPI is inoperative at night.
