Revisions to the Criteria for Municipal Solid Waste Landfills To 
Address Advances in Liquids Management; Extension of Comment Period

AGENCY: Environmental Protection Agency (EPA).

ACTION: Advance notice of proposed rulemaking; extension of comment 


SUMMARY: The Environmental Protection Agency (EPA) issued an advance 
notice of proposed rulemaking (ANPRM) in the Federal Register on 
December 26, 2018, to solicit comment on potential revisions to the 
criteria for municipal solid waste landfills and associated issues 
related to advances in liquids management. This ANPRM, entitled 
``Revisions to the Criteria for Municipal Solid Waste Landfills to 
Address Advances in Liquids Management,'' provided for a 90-day public 
comment period ending on March 26, 2019. The EPA received a number of 
requests from public interest groups for additional time to review the 
ANPRM and to develop and submit comments. This ANPRM extends the 
comment period for 45 days, from March 26, 2019, to May 10, 2019.

DATES: Comments must be received on or before May 10, 2019.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-HQ-
RCRA-2015-0354; Title: Revisions to the Criteria for Municipal Solid 
Waste Landfills to Address Advances in Liquids Management at http://www.regulations.gov. Follow the online instructions for submitting 
comments. Once submitted, comments cannot be edited or removed from 
Regulations.gov. The EPA may publish any comment received to its public 
docket. Do not submit electronically any information you consider to be 
Confidential Business Information (CBI) or other information whose 
disclosure is restricted by statute. Multimedia submissions (audio, 
video, etc.) must be accompanied by a written comment. The written 
comment is considered the official comment and should include 
discussion of all points you wish to make. EPA will generally not 
consider comments or comment contents located outside of the primary 
submission (i.e., on the web, cloud or other file sharing system). For 
additional submission methods, the full EPA public comment policy, 
information about CBI or multimedia submissions, and general guidance 
on making effective comments, please visit http://www.epa.gov/dockets/commenting-epa-dockets.

SUPPLEMENTARY INFORMATION: The EPA is considering whether to propose 
revisions to the criteria for Municipal Solid Waste Landfills (MSWLFs) 
to support advances in effective liquids management. To this end, EPA 
is seeking information relating to: removing the prohibition on the 
addition of bulk liquids to MSWLFs; defining a particular class of 
MSWLF units (i.e., bioreactor landfill units) to operate with increased 
moisture content; and establishing revised MSWLF criteria to address 
additional technical considerations associated with liquids management, 
including waste stability, subsurface reactions, and other important 
safety and operational issues. This ANPRM also discusses the results of 
related research conducted to date, describes EPA's preliminary 
analysis of that research, and seeks additional scientific studies, 
data, and public input on issues that may inform a future proposed 
rule. The EPA is not reopening any existing regulations through this 
    The ANPRM was published on December 26, 2018, and the comment 
period was scheduled to end on March 26, 2019. See 83 FR 66210. Since 
publication of the ANPRM, several stakeholders have requested 
additional time to review the ANPRM and to develop and submit comments. 
Therefore, after considering these requests for additional time, the 
EPA has decided to extend the comment period until May 10, 2019.
