Section 13103 (b) of this title, referred to in subsec. (a), was in the original “section 4 (b)” and was translated as reading “section 6604 (b)”, meaning section 6604(b) of Pub. L. 101–508, because Pub. L. 101–508 has no section 4 but section 6604(b) of Pub. L. 101–508 relates to development of a strategy to promote source reduction.
