Title 42 › Chapter CHAPTER 82— - SOLID WASTE DISPOSAL › Subchapter SUBCHAPTER IV— - STATE OR REGIONAL SOLID WASTE PLANS › § 6949a

Last updated Apr 6, 2026|Official source

Summary

The Administrator must study how well the rules for most solid waste facilities (like landfills and surface impoundments) protect people and groundwater. The study must look closely at the monitoring, prevention, and cleanup rules in sections 6907(a) and 6944 and say whether they are enough. The Administrator must also recommend any extra enforcement powers needed, after talking with the Attorney General. Within 36 months after November 8, 1984, the Administrator must send a report with the study results and recommendations to Congress. By March 31, 1988, the Administrator must update the rules for facilities that may take hazardous household waste or small-quantity-generator hazardous waste under section 6921(d). The new rules must protect health and the environment and at least require groundwater monitoring to detect contamination, set where facilities can be located, and require cleanup when needed. Groundwater monitoring rules do not apply to landfill units that take less than 20 tons per day (annual average) if there is no evidence of groundwater contamination and the landfill serves a community with either at least 3 consecutive months per year of interrupted surface transportation or no practicable alternative and annual precipitation of 25 inches or less. A State can still require monitoring, allow methods other than wells, and must require cleanup if a release is found. An approved State Director may suspend monitoring if an operator proves there is no migration risk to the uppermost aquifer during the life of the unit and post-closure; that proof must be certified by a qualified groundwater scientist and approved by the Director. The Administrator must issue guidance within 6 months after March 26, 1996 to help small communities use the no-migration option. The Governor of Alaska may let the State exempt certain Native village or small remote Alaska village landfills that take less than 20 tons per day if applying the rules would be infeasible, not cost-effective, or inappropriate because of remoteness. Finally, within two years after March 26, 1996, the Administrator must revise guidelines to give more flexibility for landfills that take 20 tons or less per day on cover practices, methane monitoring, final cover layers, and ways to show financial assurance, while still protecting health and the environment and considering climate and geology.

The Public Health and Welfare — Source: USLM XML via OLRC

(a)The Administrator shall conduct a study of the extent to which the guidelines and criteria under this chapter (other than guidelines and criteria for facilities to which subchapter III applies) which are applicable to solid waste management and disposal facilities, including, but not limited to landfills and surface impoundments, are adequate to protect human health and the environment from ground water contamination. Such study shall include a detailed assessment of the degree to which the criteria under section 6907(a) of this title and the criteria under section 6944 of this title regarding monitoring, prevention of contamination, and remedial action are adequate to protect ground water and shall also include recommendation with respect to any additional enforcement authorities which the Administrator, in consultation with the Attorney General, deems necessary for such purposes.
(b)Not later than thirty-six months after November 8, 1984, the Administrator shall submit a report to the Congress setting forth the results of the study required under this section, together with any recommendations made by the Administrator on the basis of such study.
(c)(1)Not later than March 31, 1988, the Administrator shall promulgate revisions of the criteria promulgated under paragraph (1) of section 6944(a) of this title and under section 6907(a)(3) of this title for facilities that may receive hazardous household wastes or hazardous wastes from small quantity generators under section 6921(d) of this title. The criteria shall be those necessary to protect human health and the environment and may take into account the practicable capability of such facilities. At a minimum such revisions for facilities potentially receiving such wastes should require ground water monitoring as necessary to detect contamination, establish criteria for the acceptable location of new or existing facilities, and provide for corrective action as appropriate.
(2)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)(A)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)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)If a State finds a release from a solid waste landfill unit, the State shall require corrective action as appropriate.
(4)(A)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)A demonstration under subparagraph (A) shall be certified by a qualified ground-water scientist and approved by the Director of an approved State.
(C)Not later than 6 months after March 26, 1996, the Administrator shall issue a guidance document to facilitate small community use of the no migration 11 So in original. Probably should be “no-migration”. exemption under this paragraph.
(5)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 1602 of title 43) 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)Recognizing the unique circumstances of small communities, the Administrator shall, not later than two years after March 26, 1996, promulgate revisions to the guidelines and criteria promulgated under this subchapter 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.
