Narrative:
On the wevic SID we were cleared to 16000 ft. We assumed we were cleared unrestr to this altitude. Once at that altitude; ZLC informed us that we should have crossed zoobe at 14000 ft. Controller informed us of possible ATC deviation. Controller informed us that although we were not the first to deviation from clearance; we were given the dreaded phone number to call. Honestly; I feel that the captain and I were not in error and that the clearance was misleading and confusing. ATC appeared not to be busy at this time of day and if there had been issues with this new SID; perhaps they could have clarified this 'area of confusion.' callback conversation with reporter revealed the following information: reporter could not recall whether the cleared altitude as shown on the SID was also provided in the airways clearance prior to takeoff. He advised the departure controller had issued a clearance to 16000 when they first checked on after takeoff. They assumed this canceled the intervening charted limitations at myrup and zoobe.

Title: ACR ON WEVIC RNAV SID FROM SLC FAILS TO CROSS ZOOBE AT 14000. BELIEVE CLRNC TO CLIMB TO 16000 CANCELED INTERVENING RESTRICTIONS.
Narrative: ON THE WEVIC SID WE WERE CLRED TO 16000 FT. WE ASSUMED WE WERE CLRED UNRESTR TO THIS ALT. ONCE AT THAT ALT; ZLC INFORMED US THAT WE SHOULD HAVE CROSSED ZOOBE AT 14000 FT. CTLR INFORMED US OF POSSIBLE ATC DEV. CTLR INFORMED US THAT ALTHOUGH WE WERE NOT THE FIRST TO DEV FROM CLRNC; WE WERE GIVEN THE DREADED PHONE NUMBER TO CALL. HONESTLY; I FEEL THAT THE CAPT AND I WERE NOT IN ERROR AND THAT THE CLRNC WAS MISLEADING AND CONFUSING. ATC APPEARED NOT TO BE BUSY AT THIS TIME OF DAY AND IF THERE HAD BEEN ISSUES WITH THIS NEW SID; PERHAPS THEY COULD HAVE CLARIFIED THIS 'AREA OF CONFUSION.' CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: REPORTER COULD NOT RECALL WHETHER THE CLEARED ALT AS SHOWN ON THE SID WAS ALSO PROVIDED IN THE AIRWAYS CLRNC PRIOR TO TKOF. HE ADVISED THE DEP CTLR HAD ISSUED A CLRNC TO 16000 WHEN THEY FIRST CHECKED ON AFTER TKOF. THEY ASSUMED THIS CANCELED THE INTERVENING CHARTED LIMITATIONS AT MYRUP AND ZOOBE.
