Okla. Stat. tit. 63 § 1076
In addition to the powers conferred upon an authority by other provisions of this act, an authority is empowered to borrow money or accept contributions, grants, or other financial assistance from the federal government for or in aid of any project or related activities concerning health, environmental and similar problems of persons of low income, to take over or lease or manage any project or undertaking constructed or owned by the federal government and, to these ends, to comply with such conditions and enter into such contracts, covenants, trust indentures, leases or agreements as may be necessary, convenient or desirable. It is the purpose and intent of this act to authorize any authority to do any and all things necessary or desirable to secure the financial aid or cooperation of the federal government in the provision of decent, safe, and sanitary dwellings and maintaining a wholesome living environment for persons of low income by the authority. To accomplish this purpose an authority, notwithstanding the provisions of any other law, may include in any contract for financial assistance with the federal government any provisions which the federal government may require as conditions to its financial aid not inconsistent with the purposes of this act.
