Narrative:
We took off from den. About 100 mi west, we got an EICAS message left hydraulic quantity. Left hydraulic quantity was decreasing. We looked up the procedure and followed the directions. We consulted maintenance and flight control for possible options and decided to continue to slc. Closer to slc it was determined the left hydraulic quantity was near zero. Appropriate checklists were run and we decided a safe landing could be made without assistance. We requested the long runway in slc runway 34L and asked for a long final. The gear and flaps needed to be extended using the alternate method. The procedures were followed and landing was uneventful. We taxied clear of the runway. The aircraft had degraded nosewheel steering, so the crew shut down the aircraft and asked to be towed in the ramp. The B757 has a total of 3 hydraulic system. We landed with 2 totally operational with no flight control degradation.

Title: B757 CARGO ACFT ENRTE SLC GOT AN EICAS MESSAGE REFING L HYD QUANTITY DECREASING. FOLLOWED SOP AND ELECTED TO CONTINUE TO SLC. NO DEGRADATION OF FLT CTLS AND LANDED WITHOUT DECLARING EMER. SHUT DOWN ACFT WHEN CLR OF THE RWY AND TOWED TO THE GATE.

APPROPRIATE CHKLISTS WERE RUN AND WE DECIDED A SAFE LNDG COULD BE MADE WITHOUT ASSISTANCE. WE REQUESTED THE LONG RWY IN SLC RWY 34L AND ASKED FOR A LONG FINAL. THE GEAR AND FLAPS NEEDED TO BE EXTENDED USING THE ALTERNATE METHOD. THE PROCS WERE FOLLOWED AND LNDG WAS UNEVENTFUL. WE TAXIED CLR OF THE RWY. THE ACFT HAD DEGRADED NOSEWHEEL STEERING, SO THE CREW SHUT DOWN THE ACFT AND ASKED TO BE TOWED IN THE RAMP. THE B757 HAS A TOTAL OF 3 HYD SYS. WE LANDED WITH 2 TOTALLY OPERATIONAL WITH NO FLT CTL DEGRADATION.
