Narrative:

Air carrier X inbound on camrn 2 arrival to jfk FL190 descending to 15000. Air carrier Y ewr dixie departure climbing to 16000 via dixie V-276 prepi/tsss. On contact, air carrier Y climbing to FL190 and I asked for a good rate through 15000. When I realized the climb wasn't sufficient, I stopped the climb at 14000. Air carrier X stopped descent at 15000. Sector was extremely busy with 17 aircraft on frequency and a number of pointouts. A ucr has been outstanding since sept/92 on the dixie departure and not resolved. The present procedure is unsafe and dangerous.

Title: RADAR CTLR OVERLOADED WITH TFC AND CLBED AN ACR THROUGH AN OCCUPIED ALT RESULTING IN LTSS.

Narrative: ACR X INBOUND ON CAMRN 2 ARR TO JFK FL190 DSNDING TO 15000. ACR Y EWR DIXIE DEP CLBING TO 16000 VIA DIXIE V-276 PREPI/TSSS. ON CONTACT, ACR Y CLBING TO FL190 AND I ASKED FOR A GOOD RATE THROUGH 15000. WHEN I REALIZED THE CLB WASN'T SUFFICIENT, I STOPPED THE CLB AT 14000. ACR X STOPPED DSCNT AT 15000. SECTOR WAS EXTREMELY BUSY WITH 17 ACFT ON FREQ AND A NUMBER OF POINTOUTS. A UCR HAS BEEN OUTSTANDING SINCE SEPT/92 ON THE DIXIE DEP AND NOT RESOLVED. THE PRESENT PROC IS UNSAFE AND DANGEROUS.
