Per the GIS Operating Rules, Certificates retired in a Compliance Sub-Account (Settled) are “taken out of circulation” and cannot be resettled or moved, nor can the label be changed, for any reasons, once a trading period has ended.
Post trading period close transactions can only be processed under certain circumstances:
- Rule 3.8 (d) - Unsettled (Residual Mix) to Settled (RPS retirement), Reserved (voluntary retirement) or MA DOER auction (banked for auction)
- Can only transfer if state RPS deadline is still open
- Settled to MA DOER auction
- Reserved to MA DOER auction
