SUPPLEMENTARY INFORMATION: 

I. Background

    On July 14, 2016, the U.S. Environmental Protection Agency (EPA) 
Administrator signed a final rule establishing new source performance 
standards (NSPS) intended to reduce emissions of landfill gas from new, 
modified, and reconstructed municipal solid waste (MSW) landfills, 
thereby updating standards that were issued in 1996. In a separate 
action, the Administrator also signed a final rule revising guidelines 
for reducing emissions from existing MSW landfills, thereby updating 
the previous emissions guidelines (EG), which also were issued in 1996. 
The NSPS are codified at 40 CFR part 60, subpart XXX, and the EG are 
codified at 40 CFR part 60, subpart Cf. For further information on 
these 2016 rules, see 81 FR 59332 and 81 FR 59276 (August 29, 2016).
    On October 27, 2016, a number of interested parties submitted 
administrative petitions to the EPA seeking reconsideration of various 
aspects of the 2016 rules pursuant to section 307(d)(7)(B) of the Clean 
Air Act (CAA) (42 U.S.C. 7607(d)(7)(B)).\1\ Under section 307(d)(7)(B) 
of the CAA, the Administrator shall convene a reconsideration 
proceeding if, in the Administrator's judgment, the petitioner raises 
an objection to a rule that was impracticable to raise during the 
comment period or if the grounds for the objection arose after the 
comment period, but within the period for judicial review. In either 
case, the Administrator must also conclude that the objection is of 
central relevance to the outcome of the rule. The Administrator may 
stay the effectiveness of the rule for up to 3 months during such 
reconsideration.
---------------------------------------------------------------------------

    \1\ Copies of these petitions are included in the docket for the 
2016 rules, Docket ID No. EPA-HQ-OAR-2003-0215 and EPA-HQ-OAR-2014-
0451.
---------------------------------------------------------------------------

    In a letter dated May 5, 2017, based on the criteria in CAA section 
307(d)(7)(B), the Administrator convened a proceeding for 
reconsideration. The May 5, 2017, letter announced the convening of an 
administrative reconsideration proceeding to reconsider the following 
topics from one petition: (1) Tier 4 surface emission monitoring; (2) 
annual liquids reporting; (3) corrective action

[[Page 24879]]

timeline procedures; (4) overlapping applicability with other rules; 
(5) the definition of cover penetration; and (6) design plan approval. 
As part of the proceeding, the EPA will prepare a notice of proposed 
rulemaking that will provide the petitioners and the public an 
opportunity to comment on the issues identified in that letter. As 
explained in the letter, the EPA has not taken action on the remaining 
issues in the petitions for reconsideration. A copy of the letter is 
included in the dockets for this rule, Docket ID No. EPA-HQ-OAR-2003-
0215 and EPA-HQ-OAR-2014-0451.
    The EPA convened a proceeding for reconsideration based on the 
determination that some of the objections raised in the petition for 
reconsideration met the criteria set forth in CAA section 307(d)(7)(B), 
42 U.S.C. 7607(d)(7)(B), which requires the Administrator to convene a 
proceeding for reconsideration of a rule when the person raising an 
objection to a rule can demonstrate: (1) That it was either impractical 
to raise the objection during the period for public comment or that the 
grounds for the objection arose after the period for public comment; 
and (2) that the objection is of central relevance to the outcome of 
the rule. In particular, we determined that the tier 4 surface 
emissions monitoring (SEM) issues raised in the petition for 
reconsideration met those criteria. The proposed rule included tier 4 
SEM as an optional monitoring method; however, the final rule imposed 
restrictions on the use of tier 4 SEM, e.g., limits on wind speed, the 
use of wind barriers, and restricting the use of tier 4 SEM to 
landfills with non-methane organic compounds emission rates between 34 
and 50 mega grams per year, that were not included in the proposal. 
While we believe that the restrictions are appropriate in light of the 
potential impact of the results of tier 4 SEM, we recognize that they 
were added without the benefit of public comment. Thus, we find that 
the petitioners have demonstrated that it was impractical to raise the 
objection during the period for public comment. We also find that the 
objection to the restrictions on the use of tier 4 SEM is of central 
relevance to the outcome of the rule. Tier 4 SEM can be used as a site-
specific methodology for determining whether and when the requirement 
to install a gas collection and control system is triggered. The 
restrictions limit an owner's/operator's ability to use tier 4 SEM for 
those purposes, thereby reducing intended flexibility in the rule. If 
we had the benefit of public comment on the restrictions, we might have 
structured the rule in such a way as to minimize any potential impacts 
on flexibility.

II. Stay of Subparts Cf and XXX

    By this action, the EPA is staying the subparts added or revised by 
two final rules, ``Standards of Performance for Municipal Solid Waste 
Landfills,'' 81 FR 59332 and ``Emission Guidelines and Compliance Times 
for Municipal Solid Waste Landfills,'' 81 FR 59276 for 90 days pursuant 
to its authority under section 307(d)(7)(B) of the CAA. We believe that 
it is necessary to stay the subparts in their entirety because the tier 
4 SEM provisions in the two rules are integral to how the rules 
function as a whole. The ability to use tier 4 SEM is a primary aspect 
of the flexibility we intended to include in the rule. Tier 4 SEM can 
be used to determine on a site-specific basis whether and when the 
requirement to install and operate a gas collection and control system 
is triggered. The tier 4 SEM provision provides flexibility in 
complying with other requirements in the rules that does not otherwise 
exist. As a result, we believe that it is appropriate to stay the 
subparts in their entirety while we address the tier 4 SEM issues and 
the other issues for which the Administrator has granted 
reconsideration. Therefore, pursuant to section 307(d)(7)(B) of the 
CAA, the EPA is staying 40 CFR part 60, subpart XXX, and 40 CFR part 
60, subpart Cf, for 90 days.
    This stay will remain in place until August 29, 2017.
