Response: USCG LTR: AS A RESULT OF THE COLLISION OF THE USCGC BLACK THORN WITH SS CAPRICORN ON JANUARY 29, 1980, AN AD HOC STUDY GROUP WAS CONVENED BY THE COMMANDER, SEVENTH COAST GUARD DISTRICT TO LOOK INTO NAVIGATION SAFETY IN TAMPA BAY. THE RESULTS OF THIS STUDY WILL BE USED TO EVALUATE THIS SAFETY RECOMMENDATION. WE EXPECT THIS STUDY TO BE COMPLETED AT THE END OF THIS YEAR. AS AN INTERIM SAFETY PRECAUTION, THE FOLLOWING TEMPORARY CHANGES WERE MADE PENDING THE RESULTS OF AN AD HOC STUDY GROUP: (1) A RADAR TRANSPONDER (RACON) WAS ESTABLISHED ON THE CENTER SPAN OF THE SUNSHINE SKYWAY BRIDGE FOR EVALUATION; (2) MULLET KEY CHANNEL LIGHTED BUOY 27 WAS ESTABLISHED; (3) TAMPA BAY CUT A LIGHTED BELL BUOY 1A WAS RELOCATED; AND (4) THE LIGHT ON TAMPA BAY CUT A LIGHTED 2A WAS CHANGED TO A QUICK FLASHING RED CHARACTERISTIC. PRIOR TO THE BLACKTHORN/CAPRICORN AND SUMMIT VENTURE CASUALTIES, THE COAST GUARD FUNDED A PROJECT TO REPLACE FIVE UNLIGHTED BUOYS WITH FIVE LIGHTED BUOYS AND TO ESTABLISH NINE ADDITIONAL LIGHTED BUOYS IN EGMONT AND MULLET KEY CHANNELS. THIS PROJECT WAS IN SUPPORT OF A U.S. ARMY CORPS OF ENGINEERS PROJECT TO WIDEN AND DEEPEN THE DREDGED CHANNELS IN TAMPA BAY. THESE BUOYS WILL BE ESTABLISHED AS DREDGING OF THE VARIOUS SEGMENTS OF THE CHANNEL IS COMPLETED.
