            ``(2) Definition of environmental site assessment.--For 
        purposes of this subsection, the term `environmental site 
        assessment' means an assessment conducted in accordance with 
        the standards set forth in the American Society for Testing and 
        Materials (ASTM) Standard E1527-94, titled `Standard Practice 
        for Environmental Site Assessments: Phase I Environmental Site 
        Assessment Process' or with alternative standards issued by 
        rule by the Administrator or promulgated or developed by others 
        and designated by rule by the Administrator. Before issuing or 
        designating alternative standards, the Administrator shall 
        first conduct a study of commercial and industrial practices 
        concerning environmental site assessments in the transfer of 
        real property in the United States. Any such standards issued 
        or designated by the Administrator shall also be deemed to 
        constitute commercially reasonable and generally accepted 
        standards and practices for purposes of this title. In issuing 
        or designating any such standards, the Administrator shall 
        consider requirements governing each of the following:
                    ``(A) Interviews of owners, operators, and 
                occupants of the property to determine information 
                regarding the potential for contamination.
                    ``(B) Review of historical sources as necessary to 
                determine previous uses and occupancies of the property 
                since the property was first developed. For purposes of 
                this subparagraph, the term `historical sources' means 
                any of the following, if they are reasonably 
                ascertainable: recorded chain of title documents 
                regarding the real property, including all deeds, 
                easements, leases, restrictions, and covenants, aerial 
                photographs, fire insurance maps, property tax files, 
                USGS 7.5 minutes topographic maps, local street 
                directories, building department records, zoning/land 
                use records, and any other sources that identify past 
                uses and occupancies of the property.
                    ``(C) Determination of the existence of recorded 
                environmental cleanup liens against the real property 
                which have arisen pursuant to Federal, State, or local 
                statutes.

                appropriate, investigation reports for such sites or 
                facilities; records of activities likely to cause or

                handler and generator records and spill reporting 
                records; and such other reasonably ascertainable 
                Federal, State, and local government environmental 
                records which could reflect incidents or activities 
                which are likely to cause or contribute to

                and all facilities and improvements on the real 
                property and a visual inspection of immediately

        If a copy or reasonable facsimile of a record is publicly 
        available by request (within reasonable time and cost 
        constraints) and the record is practically reviewable, the

                substances, and prevent or limit human or natural 
                resource exposure to hazardous substances previously 
                released into the environment; and

U.S.C. 9607) is further amended by adding at the end the following new 
subsection:

extent the liability of a person, with respect to a release or the 
threat of a release from a facility, is based solely on subsection 
(a)(1), the person shall not be liable under this Act if the person--
            ``(1) is a bona fide prospective purchaser of the facility 
        or an operator of a facility owned by such a bona fide 
        prospective purchaser;

        through any direct or indirect familial relationship, or any 
        contractual, corporate, or financial relationship other than 
        that created by the instruments by which title to the facility 
        is conveyed or financed.''.
    (b) Prospective Purchaser and Windfall Lien.--Section 107 of the 
Comprehensive Environmental Response, Compensation, and Liability Act 
of 1980 (as amended by subsection (a)) is amended by adding after

        has incurred unrecovered costs of response not inconsistent 
        with the National Contingency Plan at a facility for which an 
        owner of the facility is not liable by reason of subsection 
        (q), and the conditions described in paragraph (3) are met, the 
        United States shall have a lien on the facility, or may obtain, 
        from the appropriate responsible party or parties, a lien on 
        other property or other assurances of payment satisfactory to 
        the Administrator, for the unrecovered costs.
            ``(2) Amount; duration.--The lien--
                    ``(A) shall be for an amount not to exceed the

                Plan or the amount of the increase in fair market value 
                of the property attributable to the response action at 
                the time of a subsequent sale or other disposition of

                States costs of response not inconsistent with the 
                National Contingency Plan incurred at the facility, 
                notwithstanding any statute of limitations provided in 
                section 113.
        Nothing in this subsection prevents the United States and a 
        purchaser from entering into a settlement at any time that 
        extinguishes a lien under this subsection.
            ``(3) Conditions.--The conditions referred to in paragraph 
        (1) are the following:
                    ``(A) Response action.--An action for which the

                disposal of hazardous substances at the facility

                    ``(C) Notices.--The person provided all legally

                financed.''.
Adds provisions related to defenses to liability of an owner of property acquired after April 15, 1994, to deem a person to have made (under current law, "undertaken") appropriate inquiry into the property's previous ownership and uses if the person establishes that an environmental site assessment was conducted which meets specified requirements (compliance with an American Society for Testing and Materials standard or with standards issued by the Administrator of the Environmental Protection Agency) and the person fulfills certain responsibilities concerning information compilation, exercise of appropriate care with respect to hazardous substances at the facility, and cooperation with those conducting response actions.
Absolves from liability for response actions certain bona fide prospective purchasers or operators of facilities owned by such purchasers to the extent liability at a facility for a release or threat thereof is based solely on ownership or operation of a facility. Gives a lien upon a facility to the United States in any case in which there are unrecovered response costs not inconsistent with the National Contingency Plan incurred by the United States for which the owner is not liable by reason of this section and the action increases the facility's fair market value.
