RVS CTLR DESCRIBED OPERROR WHEN DEP ENTERED MVA AREA BELOW REQUIRED ALT.

Narrative

TULSA RIVERSIDE (RVS) AND TULSA INTL (TUL) ARPTS HAVE AN LOA THAT ALL IFR DEPS OFF RWYS 1L AND 1R ARE TO MAINTAIN 2500 FT MSL AND EXPECT REQUESTED ALT 10 MINS AFTER DEP. ADDITIONALLY THEY ARE ALL GIVEN A 320 DEG HDG. 13 MI NW OF RVS; THERE IS AN ANTENNA WITH AN MVA OF 3100 FT MSL FOR A 5 NM RADIUS. THE 320 DEG HDG AIMS DEPS DIRECTLY AT THE ANTENNA. DEPS MUST BE GIVEN AN ADDITIONAL TURN OR CLB PRIOR TO 8 MI OUT. EVEN IF THE DEP IS ONLY DOING 100 KTS; IT WILL BE TOO CLOSE TO THAT ANTENNA BEFORE THE 10 MIN (NORDO) ALT RESTR. TODAY; AN ACFT DEPARTED RWY 1L ON THE ABOVE HDG AND ALT PER THE LOA. UPON DEPARTING; THE RADAR TAG FOR THE ACFT DID NOT AUTO ACQUIRE. A RADAR TARGET APPEARED; BUT HAD A MODE C ALT INDICATION OF FL270. UNABLE TO POSITIVELY IDENT THE RADAR TARGET AS THE ACFT. I ISSUED THE CURRENT ALTIMETER AND ADVISED THE PLT OF THE POSSIBLE DISCREPANCY. THE PLT ACKNOWLEDGED THAT HIS MODE C WAS NOT CORRECT. I CALLED TUL TO ADVISE THEM OF THE ACFT'S POS; ALT; AND MODE C PROB. THE CTLR AT TUL TOLD ME TO 'STAND BY.' NOT HAVING THE AUTH TO CLB OR TURN THE DEP WITHOUT PERMISSION FROM TUL; THIS ALLOWED THE ACFT TO PENETRATE THE 5 MI SAFETY ZONE OF THE ANTENNA. CONTRIBUTING FACTORS: PLT DEPARTING WITH FAULTY XPONDER. POOR PROC OF AIMING ACFT AT A KNOWN OBSTACLE AT AN ALT THAT IS BELOW THE MVA. TUL CTLR SHOULD HAVE IMMEDIATELY ISSUED A TURN OR CLB RATHER THAN A STANDBY.
