(ii) A source with throughput of 10 M barrels or 200 M barrels, except the VMT source, with an initial startup date on or before September 21, 1998 shall comply with the provisions of this subpart pertaining to the RACT standards in §63.562(c) other than §63.562(c)(1), no later than 3 years after the effective date.
