(d) Publication of covered rules in Unified Agenda (1) Requirements Each agency shall, on a semiannual basis, submit jointly and without delay to the Office of Information and Regulatory Affairs for publication in the Unified Agenda a list containing— (A) each covered rule that the agency intends to issue during the 6-month period following the date of submission; (B) each covered rule that the agency intends to repeal or amend in accordance with subsection (b) during the 6-month period following the date of submission; and (C) the cost of each covered rule described in subparagraphs (A) and (B).
