Narrative:
The clearance read picah 1 departure, climb maintain 16000', expect 17000' 3 mins after departure. Contacted departure control through 2600' climbing to 16000', departure controller acknowledged. Leaving 8800' controller requested we descend back to our clearance altitude of 8000'. I explained our clearance was to 16000'. He explained as of 2/thurs/89 initial altitude on departure is 8000'. Nowhere on the SID does it say maintain 8000'. These new procedures should have been better implemented for both pilots and controllers alike. Controller error this time. Both clearance delivery and departure control acknowledged the wrong clearance altitude. Our clearance was 16000'. The readback was 16000', but because of the resectorization of phx's airspace it should have been 8000'. The departure controller should have corrected the clearance altitude on initial callup instead of acknowledging the climb to 16000'.

Title: ACR MLG ALT DEVIATION OVERSHOT DURING CLIMB ON NEW SID FROM PHX.
Narrative: THE CLRNC READ PICAH 1 DEP, CLB MAINTAIN 16000', EXPECT 17000' 3 MINS AFTER DEP. CONTACTED DEP CTL THROUGH 2600' CLBING TO 16000', DEP CTLR ACKNOWLEDGED. LEAVING 8800' CTLR REQUESTED WE DSND BACK TO OUR CLRNC ALT OF 8000'. I EXPLAINED OUR CLRNC WAS TO 16000'. HE EXPLAINED AS OF 2/THURS/89 INITIAL ALT ON DEP IS 8000'. NOWHERE ON THE SID DOES IT SAY MAINTAIN 8000'. THESE NEW PROCS SHOULD HAVE BEEN BETTER IMPLEMENTED FOR BOTH PLTS AND CTLRS ALIKE. CTLR ERROR THIS TIME. BOTH CLRNC DELIVERY AND DEP CTL ACKNOWLEDGED THE WRONG CLRNC ALT. OUR CLRNC WAS 16000'. THE READBACK WAS 16000', BUT BECAUSE OF THE RESECTORIZATION OF PHX'S AIRSPACE IT SHOULD HAVE BEEN 8000'. THE DEP CTLR SHOULD HAVE CORRECTED THE CLRNC ALT ON INITIAL CALLUP INSTEAD OF ACKNOWLEDGING THE CLB TO 16000'.
