The amendments clarify that the existing holding limits that apply to allowances with a "vintage" also apply to the "vintage less" allowances that are acquired through allowance price containment reserve (APCR) auctions and that any allowances purchased in an APCR auction must be deposited directly into the entity's compliance account.
