Narrative:

Air carrier X was landing jfk from overseas on en 1 arrival. Air carrier Y was departing bdr V139 southbound. I was working erick sector and received a pointout on air carrier Y on a 170 degree heading (so I could get air carrier X down) climbing to 12000'. Normal procedure is for the other sector to hold aircraft down to 10000' until clear of arrival traffic, then climb in erick sector airspace to requested altitude. Air carrier X wa cleared to 11000'. I then noticed air carrier Y climbing and tried to turn air carrier X, but too late. Communication between controllers was not as clear as it should have been.

Title: ACR CLIMBED TO AN OCCUPIED ALT RESULTING LESS THAN STANDARD SEPARATION.

Narrative: ACR X WAS LNDG JFK FROM OVERSEAS ON EN 1 ARR. ACR Y WAS DEPARTING BDR V139 SBND. I WAS WORKING ERICK SECTOR AND RECEIVED A POINTOUT ON ACR Y ON A 170 DEG HDG (SO I COULD GET ACR X DOWN) CLBING TO 12000'. NORMAL PROC IS FOR THE OTHER SECTOR TO HOLD ACFT DOWN TO 10000' UNTIL CLR OF ARR TFC, THEN CLB IN ERICK SECTOR AIRSPACE TO REQUESTED ALT. ACR X WA CLRED TO 11000'. I THEN NOTICED ACR Y CLBING AND TRIED TO TURN ACR X, BUT TOO LATE. COM BTWN CTLRS WAS NOT AS CLR AS IT SHOULD HAVE BEEN.
