Municipal Solid Waste Flow Control Act of 2001

Municipal Solid Waste Flow Control Act of 2001 - Amends the Solid Waste Disposal Act to authorize States and political subdivisions, under specified conditions, to exercise flow control authority for municipal solid waste and recyclable materials voluntarily relinquished by the owner or generator, directing such waste and materials to particular facilities.

Imposes identification and volume restrictions on the exercise of flow control authority to the classes or categories of materials to which such authority was applicable on the suspension date. Sets dates for expiration of such authority. Defines "suspension date" as May 16, 1994; the date of an injunction or court order based on a ruling that a State or subdivision law or official act violated the Commerce Clause of the Constitution; or the date of a suspension or partial suspension of such law or act expressly because of the existence of such injunction or order.

Imposes limitations on the use of revenues derived by a State or political subdivision from the exercise of flow control authority.

Provides for the enforceability under State law of certain legally binding interim contracts.

Allows a State to exercise flow control authority over solid waste if, on or before January 1, 1984, the State: (1) adopted regulations under a State law that required or directed the transportation, management, or disposal of such waste from residential, commercial, institutional, or industrial sources to specifically identified waste management facilities and applied those regulations to every political subdivision; and (2) subjected the facilities to the jurisdiction of a State public utilities commission.

Lists additional conditions under which solid waste districts or political subdivisions may exercise flow control authority for 20 years after this Act's enactment.
