(2) Approval of major alternatives to test methods under Sec. 63.7(e)(2)(ii) and (f), as defined in Sec. 63.90, and as required in this subpart.
(3) Approval of major alternatives to monitoring under Sec. 63.8(f), as defined in Sec. 63.90, and as required in this subpart.

Editorial Note: At 79 FR 48089, Aug. 15, 2014, Sec. 63.1309 was amended by removing paragraph (b)(4) and redesignating (b)(5) as (b)(4); however, paragraphs (b)(4) and (5) did not exist, and therefore, the amendment could not be incorporated.
