EMB145 FLT CREW HAS 'SPECIAL' COMPANY DEP PROCS FOR BUF RWY 32 AND IS UNABLE TO IDENT THE PROC.

Narrative

WE WERE FLYING THE ACFT THAT HAD THE #2 PACK DEFERRED; BUT UPON ARR AT BUF WE DISCOVERED WE HAD BEEN FILED FOR FL360. I CONTACTED DISPATCH TO GET NEW PERFORMANCE DATA ON MY CELL PHONE (AS WE WERE ALREADY LATE AND THE FUELER NEEDED TO KNOW HOW MUCH GAS WE COULD TAKE AND THE GATE AGENT NEEDED TO START ACCOMMODATING WT RESTRS). WE HAD A VERY HIGH FUEL LOAD DUE TO THE LOW ALT RESTR AND WERE VERY PERFORMANCE CRITICAL. I EXAMINED THE PERFORMANCE DATA AFTER I'D GOTTEN NEW 'NUMBERS;' AND WE WOULD BE UTILIZING A TO TKOF FROM RWY 14. THE DEP PROC NUMBERS ALLOWED A HIGHER TKOF WT; BUT I REMEMBERED ANOTHER PLT TELLING ME THAT BUF HAD A SINGLE ENG DEP PROC WHICH WAS NECESSARY TO UTILIZE THE DEP PROC NUMBERS AND THAT THE DEP PROC NUMBER ON THE APG CHART DID NOT MEAN THE BUF 1 DEP LIKE I OTHERWISE WOULD HAVE THOUGHT. I CONTACTED DISPATCH AGAIN AND AMENDED THE RELEASE AGAIN TO INCLUDE THE FOLLOWING: 'SINGLE ENG DEP PROC 14: CLB STRAIGHT AHEAD JIMUM (IBNQ ILS 136 DEG RADIAL 5.9 DME); CLB IN HOLDING PATTERN JIMUM SE R TURNS 316 DEGS INBOUND.' JIMUM WAS PHONETICALLY SPELLED SEVERAL TIMES FOR CLARITY. AS WE NEARED PUSHBACK; I ATTEMPTED TO IDENT THE JIMUM INTXN FOR THE DEP BRIEFING; BUT I COULD NOT FIND IT ON THE ILS APCH TO RWY 32 OR ANY LCL CHARTS; AND THE FMS DID NOT HAVE THE INTXN IN THE DATABASE. THE FIX APPEARED TO BE IN THE SAME LOCATION AS THE DEPEW INTXN ON THE ILS RWY 32; SO I QUERIED CLRNC DELIVERY AND THEY RPTED THAT THIS FIX NAME HAD CHANGED 'ABOUT 1 MONTH AGO.' ABOUT THE SAME TIME WE DISCOVERED THAT THEY HAD CHANGED RWYS TO 32 FOR DEP; AND SINCE WE HAD THE PERFORMANCE CAPABILITY OF OPERATING WITHOUT THE DEP PROC DESIGNATION ON THIS RWY; WE DID NOT QUERY DISPATCH AGAIN FOR THE SINGLE ENG DEP PROC FROM RWY 32. HAD I NOT BEEN TOLD BY ANOTHER CREW MEMBER ABOUT THE DEP PROC REQUIREMENT FROM RWY 32; I WOULD HAVE LIKELY ASSUMED THAT THE DEP PROC WAS THE BUFFALO 1 DEP; AND NOT THE SINGLE ENG DEP PROC. THE PROC DISPATCH HAS IN THEIR DATABASE DOES NOT HAVE AN EXISTING INTXN; AND WAS NOT ORIGINALLY PROVIDED BY THE RELEASE.
