MULTIPLE RWY OP INTERSECTING RWYS ACR X LNDG HAD LTSS FROM ACR Y TKOF. SYS ERROR.

Narrative

I WAS WORKING THE S CTL POS AT ORD ARRIVING RWY 14R DEPARTING RWY 27L. WIND CONDITIONS ALLOWED FOR RWY 14R ARRS TO BE ABLE TO HOLD SHORT OF RWY 27L DEPS. RWY 27L INTERSECTS RWY 14R AT A POINT 10000 FT DOWN RWY 14R. I HAD NO DEPS AT 27L; I CLRED A WDB TO LAND ON RWY 14R WITH NO HOLD SHORT INSTRUCTIONS BECAUSE IT WAS NOT NECESSARY BECAUSE OF THE LACK OF DEPS. HE LANDED AND CLRED AT THE T3 HIGHSPD. HE WAS FOLLOWED BY AN ACR X WDB WHO WAS ALSO CLRED TO LAND WITHOUT HOLD SHORT INSTRUCTIONS AGAIN BECAUSE OF LACK OF DEPS. WITH WDB ON SHORT FINAL; I RECEIVED AN ACR Y LGT DEP ON RWY 27L. I TAXIED HIM INTO POS AND HOLD AND ADVISED HIM OF THE RWY 14R ARR. ACR X LANDED ALMOST ON THE NUMBERS OF 14R AND WAS UNDER CTL BY THE T7 INTXN AND WAS TAXIING (ROLLING OUT) VERY SLOWLY ON RWY 14R. SEEING HE WAS UNDER CTL AND ROLLING SLOWLY I CLRED ACR Y FOR TKOF ON RWY 27L. I THEN RECEIVED A SOUTHERLY (ROBERTS) DEP STRIP AND QUICKLY COORDINATED A HDG FROM THE OTHER CTLR WHO OWNED SBOUNDS; VIA THE INTERCOM LAND LINE. I RECEIVED A HDG AND CLRED THE MLG FOR TKOF ON RWY 27L WHILE HE WAS STILL 100 YARDS FROM THE RWY. I TURNED BACK TO TURN ACR X OFF THE RWY 14R AND SAW THAT HE HAD PICKED UP HIS PACE AND WAS PASSING THE T1 INTXN HDG FOR WHICH I BELIEVE WAS RWY 27L. THE PARALLEL IS COMMONLY PREFERRED BY ACR X BECAUSE OF THE LOCATION OF THEIR CARGO FACILITY. I BECAME ALARMED THAT HE WAS HDG TOWARD RWY 27L AND ASKED IF HE CAN TURN L ON THE PARALLEL TO CLR RWY 14R. INSTEAD; HE STOPPED ABEAM THE RWY 27L PARALLEL ON RWY 14R. I REALIZED IT WAS BARRICADED. DEP ROLLED THROUGH HIS RWY INTXN POINT WHEN ACR WAS STOPPED 300 FT SHORT OF IT. I ASKED WHERE HE WAS TO PARK AND HE RESPONDED X CARGO. I THEN TURNED HIM ON RWY 27L AND CANCELLED THE STILL TAXIING MLG TKOF CLRNC WHICH HE ACKNOWLEDGED. WDB THEN TAXIED CLRED OF RWYS 27L AND 14R TO PARKING. I HAD ANTICIPATED WDB TURNING OFF THE RWY MUCH EARLIER BECAUSE OF HIS SLOW TAXIING ROLLOUT.
