ACR X NON ADHERENCE TO ATC CLRNC TCASII RA HAD LTSS FROM VFR SMA.

Narrative

ACR X MD8O DEPARTED OAK RWY 29 ON COAST SID; CLBING TO 10000 WITH RESTR OF 'X 4 DME W OF OAK AT 2000;' AND A GOVLY C182; VFR; DELAYING WITHIN CLASS B AIRSPACE AT 3500 FT; APPROX 10 NW OF SFO. THE C182 WAS WITHIN THE MD80'S DEP PATH -- BUT WAS FAR ENOUGH TO THE W OF OAK (APPROX 7- 8 MI) TO ALLOW FOR A NORMAL CLB FOR A CIVIL JET -- DEPARTING OAK TO CLB ABOVE. I RADAR IDENTIFIED THE MD80 AND CANCELED THE 2000 RESTR. I RE-EVALUATED THE SIT WHEN THE MD80 AND THE C182 WERE APPROX 5 NM APART -- AND THE MD80 WAS CLBING THROUGH 3300 FT. BASED UPON THIS PERFORMANCE; I BELIEVED THERE WOULD NOT BE A PROB OBTAINING 500 FT VERT SEPARATION. FOR THE NEXT 2-3 MI; HOWEVER; THE MD80 LEVELED AT 3600 FT (THE C182 WAS AT 3500). THE MD80 APPEARED TO HAVE STOPPED CLBING -- SO I THEN TOLD X TO 'EXPEDITE THROUGH 4000 FT;' AND ISSUED TFC ON THE C182. THE CREW OF THE MD80 THEN ADVISED ME THAT THEY WERE RESPONDING TO AN 'RA;' BUT STILL APPEARED LEVEL AT 3600 TO 3700. THE CREW RPTED THE C182 'IN SIGHT;' BUT WITH LESS THAN REQUIRED SEPARATION. AFTER THE ACFT REPLIED; I ASKED THE CREW WHY THEY HAD LEVELED OFF; AS I WAS COUNTING ON A NORMAL CLB RATE TO ACHIEVE SEPARATION AND THEY RESPONDED THAT THE TCASII HAD INSTRUCTED THEM TO DSND. I DO NOT THINK THE CREW ACTUALLY DSNDED -- BASED UPON MODE C INFO. I HAVE NO IDEA WHY THEY LEVELED AT AN ALT MATCHING THE ALT OF THE TARGET. PERHAPS IF I HAD ISSUED TFC INFO SOONER; TO LET THE CREW KNOW OF MY INTENTIONS; THIS SIT COULD HAVE BEEN AVOIDED.
