January 8, 1990 Clarification on Two Questions Concerning "Secondary Emissions" as Defined in the Code of Federal Regulations (CFR) at 40 CFR 52.21(b)(18) 5.26

(1) The definition of secondary emissions in the 1988 CFR at 40 CFR 52.21(b)(18) is incomplete; the second sentence was inadvertently omitted by the Federal Register during revision.

(2) Portions of the 1982 revisions to the PSD regulations have been vacated and remanded to EPA, including the way the Agency treats vessel emissions. Consequently, the August 7, 1980, PSD regulations, with the exception of to and from emissions counting, shall apply to determinations on how to treat vessel emissions. Under the 1980 regulations, emissions from certain activities of a ship docked at a terminal may be considered terminal emissions.
