IIRC, the runways are not far enough apart to comply with international standards for independent operations
Yes, but that doesn't necessarily preclude them. The CAA's view:
"The current ICAO separation for allowing independent approaches
with no mitigations is 1525m.The existing runway separation is approximately 1450m and the proposed northern runway separation is 1035m from the existing northern runway. The proposer must demonstrate that the design meets the requirements of ICAO Document 9643 The Manual on Simultaneous Parallel or Near Parallel Instrument Runways (SOIR) for all possible modes of operation, in particular given the stagger of the proposed northern runway.
Appropriate mitigations will need to be provided."
