II. Proposed Rule Summary and Rationale

In 1998 the EPA promulgated National Emission Standards for
Hazardous Air Pollutants (NESHAP) for the Oil and Natural Gas
Production Facility and Natural Gas Transmission and Storage Facility
Source Categories, 40 CFR part 63, subparts HH and HHH. 64 FR 32610
(June 17, 1999) (``Oil and Gas NESHAP''). In 2012, the EPA amended the
Oil and Gas NESHAP. 77 FR 49490 (August 16, 2012). The 2012 amendments
included provisions allowing owners and operators to assert an
affirmative defense to civil penalties for violations caused by
malfunctions. See 40 CFR 63.762 and 63.1672. Malfunctions are a sudden,
infrequent, and not reasonably preventable failure of air pollution
control and monitoring equipment, process equipment, or a process to
operate in a normal or usual manner. See 40 CFR 63.2. As defined in 40
CFR part 63, subparts HH and HHH, ``affirmative defense'' means, ``in
the context of an enforcement proceeding, a response or defense put
forward by a defendant, regarding which the defendant has the burden of
proof, and the merits of which are independently and objectively
evaluated in a judicial or administrative proceeding.'' See 40 CFR
63.761 and 63.1271. The EPA established an affirmative defense in 40
CFR part 63, subparts HH and HHH in an effort to create a system that
incorporates some flexibility, recognizing that there is a tension,
inherent in many types of air regulations, to ensure adequate
compliance while simultaneously recognizing that despite the most
diligent of efforts, emission standards may be violated under
circumstances entirely beyond the control of the source (77 FR 49508).
Although the EPA recognized at the time that its case-by-case
enforcement discretion provides sufficient flexibility in these
circumstances, it included the affirmative defense to provide a more
formalized approach and more regulatory clarity. Id. at 49508-9. See
also, Weyerhaeuser Co. v. Costle, 590 F.2d 1011, 1057-58 (D.C. Cir.
1978) (holding that an informal case-by-case enforcement discretion
approach is adequate); but see Marathon Oil Co. v. EPA, 564 F.2d 1253,
1272-73 (9th Cir. 1977) (requiring a more formalized approach to
consideration of ``upsets beyond the control of the permit holder'').
Under the EPA's regulatory affirmative defense provisions, if a source
could demonstrate in a judicial or administrative proceeding that it
had met the requirements of the affirmative defense in the regulation,
civil penalties would not be assessed.
In 2014, the United States Court of Appeals for the District of
Columbia Circuit (D.C. Circuit Court) vacated the affirmative defense
in one of the EPA's CAA section 112 regulations. Natural Resource
Defense Council (NRDC) v. EPA, 749 F.3d 1055 (D.C. Cir., 2014)
(vacating affirmative defense provisions in CAA section 112 rule
establishing emission standards for Portland cement kilns) (NRDC). The
court found that the EPA lacked authority to establish an affirmative
defense for private civil suits and held that under the CAA, the
authority to determine civil penalty amounts in such cases lies
exclusively with the courts, not the EPA. Specifically, the court
found: ``As the language of the statute makes clear, the courts
determine, on a case-by-case basis, whether civil penalties are
`appropriate.' '' Id. at 1063 (``[U]nder this statute, deciding whether
penalties are `appropriate' in a given private civil suit is a job for
the courts, not EPA.'').\1\
---------------------------------------------------------------------------

\1\ The court's reasoning in NRDC focuses on civil judicial
actions. The court noted that ``EPA's ability to determine whether
penalties should be assessed for CAA violations extends only to
administrative penalties, not to civil penalties imposed by a
court.'' Id.
---------------------------------------------------------------------------

In light of the NRDC decision mentioned above, the EPA is proposing
to remove the affirmative defense provisions from the Oil and Gas
NESHAP. These provisions imply legal authority that the D.C. Circuit
Court has stated that the EPA does not have.\2\ As explained above, if
a source is unable to comply with emissions standards as a result of a
malfunction, the EPA may use its case-by-case enforcement discretion to
provide flexibility, as appropriate. Further, as the D.C. Circuit
recognized, in a citizen enforcement action brought under CAA section
304(a), the court has the discretion to consider any defense raised and
determine whether penalties are appropriate. Cf. NRDC, 749 F.3d at 1064
(arguments that violation was caused by unavoidable technology failure
can be made to the courts in future civil cases when the issue arises).
The same is true for the presiding officer in EPA administrative
enforcement actions.\3\
---------------------------------------------------------------------------

\2\ The EPA notes that in 2012, concurrent with the review of 40
CFR part 63, subparts HH and HHH, the EPA promulgated New Source
Performance Standards for Crude Oil and Natural Gas Facilities, 40
CFR part 60, subpart OOOO (``NSPS OOOO''), which also included an
affirmative defense. See 77 FR 49557. In a subsequent rulemaking
following the NRDC decision, the EPA removed the affirmative defense
provision from NSPS OOOO. 79 FR 79018 (Dec. 31, 2014).
\3\ Although the NRDC case does not address the EPA's authority
to establish an affirmative defense to penalties that are available
in administrative enforcement actions, we are not including such an
affirmative defense in the proposed rule. As explained above, such
an affirmative defense is not necessary. Moreover, assessment of
penalties for violations caused by malfunctions in administrative
proceedings and judicial proceedings should be consistent. Cf. CAA
section 113(e) (requiring both the Administrator and the court to
take specified criteria into account when assessing penalties).
---------------------------------------------------------------------------

III. Summary of Cost, Environmental, and Economic Impacts

A. What are the affected sources?

Sources subject to subparts HH and HHH under 40 CFR part 63 of the
CAA as amended in 1990, section 112.

B. What are the air quality impacts?

There are no air quality impacts associated with this action. The
affirmative defense provisions did not affect the stringency of the
standards in 40 CFR part 63, subparts HH or HHH. The removal of the
provisions does not have a material impact on the obligation for
sources to comply with current existing standards, or the ability of
Federal or State agencies to enforce standards.

[[Page 83892]]

C. What are the cost impacts?

There are no cost impacts associated with this action. The
affirmative defense provisions did not affect the stringency of the
standards in 40 CFR part 63, subparts HH or HHH. The removal of the
provisions does not have a material impact on the obligation for
sources to comply with current existing standards, or the ability of
Federal or State agencies to enforce standards. The EPA estimated a
small administrative burden to report deviations from standards as a
result of malfunctions that included the option for an owner or
operator to offer an affirmative defense. The removal of the
affirmative defense provisions does not affect that burden because
sources will still be required to report malfunctions that result in a
failure to meet the standards. Since the option to invoke an
affirmative defense was voluntary, there may be a negligible cost
savings for reporting malfunctions by removing these provisions.

D. What are the economic impacts?

There are no economic impacts associated with this action. The
affirmative defense provisions did not affect the stringency of the
standards in 40 CFR part 63, subparts HH or HHH. The removal of the
provisions does not have a material impact on the obligation for
sources to comply with current existing standards, or the ability of
Federal or State agencies to enforce standards. The EPA estimated a
small administrative burden to report deviations from standards as a
result of malfunctions that included the option for an owner or
operator to offer an affirmative defense. The removal of the
affirmative defense provisions does not affect that burden because
sources will still be required to report malfunctions that could have
resulted in a failure to meet the standards. Since the option to invoke
an affirmative defense was voluntary, there may be a negligible cost
savings for reporting malfunctions by removing these provisions.

E. What are the benefits?

There are no environmental benefits associated with this action.
The affirmative defense provisions did not affect the stringency of the
standards in 40 CFR part 63, subparts HH or HHH. The removal of the
provisions does not have a material impact on the obligation for
sources to comply with current existing standards, or the ability of
Federal or State agencies to enforce standards.

IV. Statutory and Executive Order Reviews

Additional information about these statutes and Executive Orders
can be found at <a href="https://www.epa.gov/laws-regulations/laws-and-executive-orders">https://www.epa.gov/laws-regulations/laws-and-executive-orders</a>.

A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 14094: Modernizing Regulatory Review

This action is not a significant regulatory action as defined in
Executive Order 12866, as amended by Executive Order 14094, and was
therefore not subject to a requirement for review under Executive Order
12866.

B. Paperwork Reduction Act (PRA)

This action does not impose any new information collection burden
under the PRA. OMB has previously approved the information collection
activities contained in the existing regulations and has assigned OMB
control number 2060-0417. The removal of provisions for affirmative
defense does not change any mandatory recordkeeping, reporting, or
other activity previously established under prior final rules.

C. Regulatory Flexibility Act (RFA)

I certify that this action will not have a significant economic
impact on a substantial number of small entities under the RFA. There
are no economic impacts associated with this action. The affirmative
defense provisions did not affect the stringency of the standards in 40
CFR part 63, subparts HH or HHH. The removal of the provisions does not
have a material impact on the obligation for sources to comply with
current existing standards, or the ability of Federal or State agencies
to enforce standards.

D. Unfunded Mandates Reform Act (UMRA)

This action does not contain any unfunded mandate as described in
UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect
small governments. The action imposes no enforceable duty on any State,
local or Tribal governments or the private sector.

E. Executive Order 13132: Federalism

This action does not have federalism implications. It will not have
substantial direct effects on the States, on the relationship between
the national government and the States, or on the distribution of power
and responsibilities among the various levels of government.

F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments

This action does not have Tribal implications as specified in
Executive Order 13175. It will not have substantial direct effects on
Tribal governments, on the relationship between the Federal Government
and Indian tribes, or on the distribution of power and responsibilities
between the Federal Government and Indian tribes, as specified in
Executive Order 13175. Thus, Executive Order 13175 does not apply to
this action.

G. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks

The EPA interprets Executive Order 13045 as applying only to those
regulatory actions that concern environmental health or safety risks
that the EPA has reason to believe may disproportionately affect
children, per the definition of ``covered regulatory action'' in
section 2-202 of the Executive order. Therefore, this action is not
subject to Executive Order 13045 because it does not concern an
environmental health risk or safety risk. Since this action does not
concern human health, the EPA's Policy on Children's Health also does
not apply.

H. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution or Use

This action is not subject to Executive Order 13211, because it is
not a significant regulatory action under Executive Order 12866.

I. National Technology Transfer and Advancement Act (NTTAA)

This rulemaking does not involve technical standards.

J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations and
Executive Order 14096: Revitalizing our Nation's Commitment to
Environmental Justice for All

The EPA believes that this action does not concern human health or
environmental conditions and therefore cannot be evaluated with respect
to potentially disproportionate and adverse effects on people of color,
low-income populations and/or Indigenous peoples. The removal of the
provisions does not have a material impact on the obligation for
sources to comply with current existing standards, or the ability of
Federal or State agencies to enforce standards.
