In the section, the word “agency” is substituted for “board or commission” for consistency in the revised title. Before clause (1), the words “executive agency” are substituted for “Federal department or agency” because of the definition in sections 102 and 6501(3) of the revised title. The words “appropriate” and “determining or revising” are omitted as surplus. The words “Governor or other” are omitted as covered by “executive . . . authority”. In clause (2), the words “after deciding” are substituted for “Provided, That the head of the Federal department or agency determines” to eliminate unnecessary words.
