Help with statement

Question

Dear all
I have a process where I have 60 million rows of data in one table. I need to check each row in the table and if the row doesn't exist in my lookup table then I need to remove the row.
Currently this is done by selecting the 60 million rows into a pl/sq table (bulk select fetching 100 rows at a time) and then looping round the pl/sql table checking each row against the lookup table. If the row isn't in the lookup table, the row is deleted from the pl/sql table. Finally all remaining rows in the pl/sql table are bulk inserted into a new table.
Please can anyone provide a better way of doing this?
Many thanks

sorry.. I posted the wrong plan. Here is the one for the delete:
PLAN_TABLE_OUTPUT
Plan hash value: 1388979655
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time |
| 0 | DELETE STATEMENT | | 41M| 4299M| 129M (4)|433:17:08 |
| 1 | DELETE | GENEVA_INTERFACE_TABLE | | | | |
|* 2 | FILTER | | | | | |
| 3 | TABLE ACCESS FULL| GENEVA_INTERFACE_TABLE | 41M| 4299M| 132K (3)| 00:26:32 |
|* 4 | TABLE ACCESS FULL| GV_ACCEPTABLE_TAGS | 6 | 78 | 3 (0)| 00:00:01 |
PLAN_TABLE_OUTPUT
Predicate Information (identified by operation id):
2 - filter( NOT EXISTS (SELECT /*+ */ 0 FROM "GV_ACCEPTABLE_TAGS" "T" WHERE
"T"."TAG_NAME"=SUBSTR(:B1,1,INSTR(:B2,' '))))
4 - filter("T"."TAG_NAME"=SUBSTR(:B1,1,INSTR(:B2,' ')))
sorry.....
