WX: west 3X 3/4 s-f, RVV runway 36 3/8 mi. Small aircraft on ILS runway 36 with approximately 6 KT tailwind. Air carrier light transport taxied into position runway 13 to hold for the small aircraft. With steady snow the light transport was just deiced. I visually picked up small aircraft over numbers of runway 36 approximately 300-500' above runway. At this point the small aircraft started to descend and requested a clearance to circle to runway 13 (he had already initiated a turn). As the small aircraft made his request and started his turn, he had a hot microphone. As I said, we had poor visibility with snow and fog, with obstructions, mountains and other high terrain just north of the field. The decision to circle to runway 13, below circling minimums with the light transport in position on the runway, plus a hot microphone, made this a very dangerous situation. When I finally got through to the small aircraft to execute a missed approach, I advised unable runway 13 due to aircraft in position. He was dangerously low and still dirtied up. Scared the hell out of me, and the hot microphone didn't help.

Title: SMA COMMENCED A CIRCLING APCH BELOW MINIMUMS.
Narrative: WX: W 3X 3/4 S-F, RVV RWY 36 3/8 MI. SMA ON ILS RWY 36 WITH APPROX 6 KT TAILWIND. ACR LTT TAXIED INTO POS RWY 13 TO HOLD FOR THE SMA. WITH STEADY SNOW THE LTT WAS JUST DEICED. I VISUALLY PICKED UP SMA OVER NUMBERS OF RWY 36 APPROX 300-500' ABOVE RWY. AT THIS POINT THE SMA STARTED TO DSND AND REQUESTED A CLRNC TO CIRCLE TO RWY 13 (HE HAD ALREADY INITIATED A TURN). AS THE SMA MADE HIS REQUEST AND STARTED HIS TURN, HE HAD A HOT MIC. AS I SAID, WE HAD POOR VISIBILITY WITH SNOW AND FOG, WITH OBSTRUCTIONS, MOUNTAINS AND OTHER HIGH TERRAIN JUST N OF THE FIELD. THE DECISION TO CIRCLE TO RWY 13, BELOW CIRCLING MINIMUMS WITH THE LTT IN POS ON THE RWY, PLUS A HOT MIC, MADE THIS A VERY DANGEROUS SITUATION. WHEN I FINALLY GOT THROUGH TO THE SMA TO EXECUTE A MISSED APCH, I ADVISED UNABLE RWY 13 DUE TO ACFT IN POS. HE WAS DANGEROUSLY LOW AND STILL DIRTIED UP. SCARED THE HELL OUT OF ME, AND THE HOT MIC DIDN'T HELP.
