Subsection (b)(1) is substituted for “results of the analysis required by section 762a(b)(3) of this title” because 40:762a(b)(3), which is omitted as executed and obsolete (see the revision note for section 18102(b) of the revised title), provided for an analysis and report regarding modifications that the Administrator determined were necessary to achieve the objectives of 40:762a(a), which is restated in section 18102(a) of the revised title.
