D.C. Code § 6-219

(a) Until the Board promulgates procurement regulations in accordance with this section, the Authority’s existing rules governing procurement shall continue to apply. The Board shall transmit proposed procurement regulations to the Council for a 45-day period of review, excluding Saturdays, Sundays, legal holidays, and days of Council recess. If the Council does not approve or disapprove the regulations, in whole or in part, by resolution within the 45-day review period, the regulations shall be deemed approved. The Board’s procurement regulations shall include rules and procedures governing public notice of invitations to bid; methods of source selection, including competitive sealed bidding and competitive sealed proposals; small purchase procurements; cost principles; delivery and performance; contract modification; and contract termination.
(b) Nothing in this subsection shall exempt the Board from compliance with § 1-204.51 ; however, the Board may adopt rules governing procurements involving the expenditure of federal funds that are inconsistent with Chapter 3A of Title 2 .
