The Environmental Protection Agency
(EPA) is issuing a supplemental proposal for the Standards of
Performance for Municipal Solid Waste (MSW) Landfills to address
the nonmethane organic compound (NMOC) emission rate threshold at
which an affected MSW landfill must install controls. The EPA is in
the process of reviewing the Standards of Performance for MSW
Landfills based on changes in the landfills industry since the
standards were promulgated in 1996 and issued a proposed rulemaking
on July 17, 2014. EPA's review of the Standards of Performance for
MSW Landfills (also referred to as the New Source Performance
Standards or NSPS for MSW Landfills) applies to landfills that
commenced construction, reconstruction, or modification after July
17, 2014. This document proposes to achieve additional reductions
of landfill gas (LFG) and its components, including methane,
through a lower emission threshold at which MSW landfills must
install and operate a gas collection and control system (GCCS).
This document supplements the initial proposed rulemaking by
further lowering, from 40 megagrams per year (Mg/yr) to 34 Mg/yr,
the proposed NMOC emissions threshold at which controls would be
required. This change to the 2014 proposed threshold is based on
additional data we have reviewed that indicate greater potential
for reductions in methane emissions from these sources than we
originally estimated that can be achieved at reasonable cost.
Accordingly, the EPA is proposing to establish the NMOC emission
rate threshold for installing a GCCS at 34 Mg/yr.
As a result of lowering the
NMOC emission rate threshold to from 40 Mg/yr to 34 Mg/yr, and
revising the estimates to account for the burden on modified
landfills, the estimated number of landfills required to install
controls have increased. Thus, the burden hours, costs, and number
of responses have increased compared to the initial proposed
rule.
On behalf of this Federal agency, I certify that
the collection of information encompassed by this request complies
with 5 CFR 1320.9 and the related provisions of 5 CFR
1320.8(b)(3).
The following is a summary of the topics, regarding
the proposed collection of information, that the certification
covers:
(i) Why the information is being collected;
(ii) Use of information;
(iii) Burden estimate;
(iv) Nature of response (voluntary, required for a
benefit, or mandatory);
(v) Nature and extent of confidentiality; and
(vi) Need to display currently valid OMB control
number;
If you are unable to certify compliance with any of
these provisions, identify the item by leaving the box unchecked
and explain the reason in the Supporting Statement.
