Land Disposal Program Flexibility Act of 1996

SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Land Disposal Program Flexibility 
Act of 1996''.

SEC. 2. LAND DISPOSAL RESTRICTIONS.

    Section 3004(g) of the Solid Waste Disposal Act is amended by 
adding after paragraph (6) the following:
        ``(7) Solid waste identified as hazardous based solely on one 
    or more characteristics shall not be subject to this subsection, 
    any prohibitions under subsection (d), (e), or (f), or any 
    requirement promulgated under subsection (m) (other than any 
    applicable specific methods of treatment, as provided in paragraph 
    (8)) if the waste--
            ``(A) is treated in a treatment system that subsequently 
        discharges to waters of the United States pursuant to a permit 
        issued under section 402 of the Federal Water Pollution Control 
        Act (commonly known as the ``Clean Water Act'') (33 U.S.C. 
        1342), treated for the purposes of the pretreatment 
        requirements of section 307 of the Clean Water Act (33 U.S.C. 
        1317), or treated in a zero discharge system that, prior to any 
        permanent land disposal, engages in treatment that is 
        equivalent to treatment required under section 402 of the Clean 
        Water Act (33 U.S.C. 1342) for discharges to waters of the 
        United States, as determined by the Administrator; and
            ``(B) no longer exhibits a hazardous characteristic prior 
        to management in any land-based solid waste management unit.
        ``(8) Solid waste that otherwise qualifies under paragraph (7) 
    shall nevertheless be required to meet any applicable specific 
    methods of treatment specified for such waste by the Administrator 
    under subsection (m), including those specified in the rule 
    promulgated by the Administrator June 1, 1990, prior to management 
    in a land-based unit as part of a treatment system specified in 
    paragraph (7)(A). No solid waste may qualify under paragraph (7) 
    that would generate toxic gases, vapors, or fumes due to the 
    presence of cyanide when exposed to pH conditions between 2.0 and 
    12.5.
        ``(9) Solid waste identified as hazardous based on one or more 
    characteristics alone shall not be subject to this subsection, any 
    prohibitions under subsection (d), (e), or (f), or any requirement 
    promulgated under subsection (m) if the waste no longer exhibits a 
    hazardous characteristic at the point of injection in any Class I 
    injection well permitted under section 1422 of title XIV of the 
    Public Health Service Act (42 U.S.C. 300h-1).
        ``(10) Not later than five years after the date of enactment of 
    this paragraph, the Administrator shall complete a study of 
    hazardous waste managed pursuant to paragraph (7) or (9) to 
    characterize the risks to human health or the environment 
    associated with such management. In conducting this study, the 
    Administrator shall evaluate the extent to which risks are 
    adequately addressed under existing State or Federal programs and 
    whether unaddressed risks could be better addressed under such laws 
    or programs. Upon receipt of additional information or upon 
    completion of such study and as necessary to protect human health 
    and the environment, the Administrator may impose additional 
    requirements under existing Federal laws, including subsection 
    (m)(1), or rely on other State or Federal programs or authorities 
    to address such risks. In promulgating any treatment standards 
    pursuant to subsection (m)(1) under the previous sentence, the 
    Administrator shall take into account the extent to which treatment 
    is occurring in land-based units as part of a treatment system 
    specified in paragraph (7)(A).
        ``(11) Nothing in paragraph (7) or (9) shall be interpreted or 
    applied to restrict any inspection or enforcement authority under 
    the provisions of this Act.''.

SEC. 3. GROUND WATER MONITORING.

    (a) Amendment of Solid Waste Disposal Act.--Section 4010(c) of the 
Solid Waste Disposal Act (42 U.S.C. 6949a(c)) is amended as follows:

        ``(2) Additional revisions.--Subject to paragraph (3), the 
    requirements of the criteria described in paragraph (1) relating to 
    ground water monitoring shall not apply to an owner or operator of 
    a new municipal solid waste landfill unit, an existing municipal 
    solid waste landfill unit, or a lateral expansion of a municipal 
    solid waste landfill unit, that disposes of less than 20 tons of 
    municipal solid waste daily, based on an annual average, if--
            ``(A) there is no evidence of ground water contamination 
        from the municipal solid waste landfill unit or expansion; and
            ``(B) the municipal solid waste landfill unit or expansion 
        serves--
                ``(i) a community that experiences an annual 
            interruption of at least 3 consecutive months of surface 
            transportation that prevents access to a regional waste 
            management facility; or
                ``(ii) a community that has no practicable waste 
            management alternative and the landfill unit is located in 
            an area that annually receives less than or equal to 25 
            inches of precipitation.
        ``(3) Protection of ground water resources.--
            ``(A) Monitoring requirement.--A State may require ground 
        water monitoring of a solid waste landfill unit that would 
        otherwise be exempt under paragraph (2) if necessary to protect 
        ground water resources and ensure compliance with a State 
        ground water protection plan, where applicable.
            ``(B) Methods.--If a State requires ground water monitoring 
        of a solid waste landfill unit under subparagraph (A), the 
        State may allow the use of a method other than the use of 
        ground water monitoring wells to detect a release of 
        contamination from the unit.
            ``(C) Corrective action.--If a State finds a release from a 
        solid waste landfill unit, the State shall require corrective 
        action as appropriate.
        ``(4) No-migration exemption.--
            ``(A) In general.--Ground water monitoring requirements may 
        be suspended by the Director of an approved State for a 
        landfill operator if the operator demonstrates that there is no 
        potential for migration of hazardous constituents from the unit 
        to the uppermost aquifer during the active life of the unit and 
        the post-closure care period.
            ``(B) Certification.--A demonstration under subparagraph 
        (A) shall be certified by a qualified ground-water scientist 
        and approved by the Director of an approved State.
            ``(C) Guidance.--Not later than 6 months after the date of 
        enactment of this paragraph, the Administrator shall issue a 
        guidance document to facilitate small community use of the no 
        migration exemption under this paragraph.
        ``(5) Alaska native villages.--Upon certification by the 
    Governor of the State of Alaska that application of the 
    requirements described in paragraph (1) to a solid waste landfill 
    unit of a Native village (as defined in section 3 of the Alaska 
    Native Claims Settlement Act (16 U.S.C. 1602)) or unit that is 
    located in or near a small, remote Alaska village would be 
    infeasible, or would not be cost-effective, or is otherwise 
    inappropriate because of the remote location of the unit, the State 
    may exempt the unit from some or all of those requirements. This 
    paragraph shall apply only to solid waste landfill units that 
    dispose of less than 20 tons of municipal solid waste daily, based 
    on an annual average.
        ``(6) Further revisions of guidelines and criteria.--
    Recognizing the unique circumstances of small communities, the 
    Administrator shall, not later than two years after enactment of 
    this provision promulgate revisions to the guidelines and criteria 
    promulgated under this subtitle to provide additional flexibility 
    to approved States to allow landfills that receive 20 tons or less 
    of municipal solid waste per day, based on an annual average, to 
    use alternative frequencies of daily cover application, frequencies 
    of methane gas monitoring, infiltration layers for final cover, and 
    means for demonstrating financial assurance: Provided, That such 
    alternative requirements take into account climatic and 
    hydrogeologic conditions and are protective of human health and 
    environment.''.
    (b) Reinstatement of Regulatory Exemption.--It is the intent of 
section 4010(c)(2) of the Solid Waste Disposal Act, as added by 
subsection (a), to immediately reinstate subpart E of part 258 of title 
40, Code of Federal Regulations, as added by the final rule published 
at 56 Federal Register 50798 on October 9, 1991.

Summary: Land Disposal Program Flexibility Act of 1996 - Amends the Solid Waste Disposal Act (SWDA) to exempt from land disposal restrictions solid waste identified as hazardous based solely on one or more characteristics if such waste: (1) is treated in a treatment system that subsequently discharges to waters of the United States pursuant to a permit issued under the Federal Water Pollution Control Act , undergoes pretreatment for purposes of compliance with toxic and pretreatment effluent standards of such Act, or is treated in a zero-discharge system that the Administrator determines to be engaging in Clean Water Act-equivalent treatment, (2) no longer exhibits such characteristic prior to land disposal. (3) has met any applicable specific method of treatment promulgated by the Administrator, including those specified in the rule promulgated by the Administrator on June 1, 1990, prior to management in a land-based unit as part of a treatment system specified in clause (1) above. And (4) would not generate toxic gases, vapors, or fumes due to the presence of cyanide at the point of generation when exposed to pH conditions of a specified range. Amends SWDA to exempt from land disposal restrictions solid waste identified as hazardous based on one or more characteristics alone if the waste no longer exhibits a hazardous characteristic at the point of injection into any Class I deep well regulated under safe drinking water provisions of the Public Health Service Act. Requires the Administrator to conduct a study of hazardous waste managed in accordance with this Act to characterize the risks to human health or the environment associated with such management, upon completion of which the Administrator may impose additional requirements or rely upon other State or Federal programs or authorities to address such risks. Makes certain groundwater monitoring requirements inapplicable to new or existing municipal solid waste landfill units or lateral expansions of such units that dispose of fewer than 20 tons of municipal solid waste daily, based on an annual average, if: (1) there is no evidence of groundwater contamination from such units or expansions. And (2) the units or expansions serve a community that experiences an annual interruption of at least three consecutive months of surface transportation that prevents access to a regional waste management facility or that has no practicable waste management alternative and such units are located in an area that annually receives 25 inches of precipitation or less. Permits States to require monitoring of units that would otherwise be exempt if necessary to protect groundwater resources and ensure compliance with a State groundwater protection plan. Allows the suspension of groundwater monitoring requirements if a landfill operator demonstrates that there is no potential for migration of hazardous constituents from the unit to the uppermost aquifer during the active life of the unit and the post-closure care period. Allows the State of Alaska to exempt units of Alaska Native villages or located in or near small, remote Alaska villages from some or all of such requirements if such requirements would be infeasible, would not be cost-effective, or would be inappropriate because of the unit's remote location. Applies this exemption only to landfills that dispose of less than 20 tons of municipal solid waste daily. Directs the Administrator to promulgate revisions to provide additional flexibility to approved States to allow landfills that receive no more than 20 tons of municipal solid waste daily to use alternative frequencies of daily cover application and methane gas monitoring, infiltration layers for final cover, and means for demonstrating financial assurance, provided such alternative requirements take into account climatic and hydrogeologic conditions and protect human health and the environment. Declares that it is the intent of this Act to reinstate EPA rules promulgated on October 9, 1991, regarding groundwater monitoring at municipal solid waste landfill units.
