XIV. Statutory and Executive Order Reviews
I. What does this action do?
The EPA is updating the delegation of the implementation and
enforcement of certain NSPS to LDEQ. EPA is also proposing to approve
the delegation of the implementation and enforcement of certain NESHAP
to LDEQ. If finalized, the delegation will provide LDEQ with the
primary responsibility to implement and enforce the delegated
standards.
II. What is the authority for delegation?
Section 111(c)(1) of the Clean Air Act (CAA) authorizes EPA to
delegate authority to any State agency which submits adequate
regulatory procedures for implementation and enforcement of the NSPS
program. The NSPS standards are codified at 40 CFR part 60.
Section 112(l) of the Clean Air Act (CAA), and 40 CFR part 63,
subpart E, authorize the EPA to delegate authority to any State or
local agency which submits adequate regulatory procedures for
implementation and enforcement of emission standards for hazardous air
pollutants. The hazardous air pollutant standards are codified at 40
CFR parts 61 and 63.
III. What criteria must Louisiana's programs meet to be approved?
In order to receive delegation of NSPS, a State must develop and
submit to the EPA a procedure for implementing and enforcing the NSPS
in the State, and their regulations and resources must be adequate for
the implementation and enforcement of the NSPS. EPA initially approved
Louisiana's program for the delegation of NSPS on February 22, 1982 (47
FR 7665). EPA reviewed the laws of the State and the rules and
regulations of the Louisiana Department of Natural Resources (now the
LDEQ) and determined the State's procedures, regulations and resources
adequate for the implementation and enforcement of the NSPS program.
This action notifies the public that EPA is updating LDEQ's delegation
to implement and enforce certain additional NSPS.
As to the NESHAP standards in 40 CFR parts 61 and 63, Section
112(l)(5) of the CAA requires the EPA to disapprove any program
submitted by a State for the delegation of NESHAP standards if the EPA
determines that:
(A) the authorities contained in the program are not adequate to
assure compliance by the sources within the State with respect to each
applicable standard, regulation, or requirement established under
section 112;
(B) adequate authority does not exist, or adequate resources are
not available, to implement the program;
(C) the schedule for implementing the program and assuring
compliance by affected sources is not sufficiently expeditious; or
(D) the program is otherwise not in compliance with the guidance
issued by the EPA under section 112(l)(2) or is not likely to satisfy,
in whole or in part, the objectives of the CAA.
In carrying out its responsibilities under section 112(l), the EPA
promulgated regulations at 40 CFR part 63, subpart E, setting forth
criteria for the approval of submitted programs. For example, in order
to obtain approval of a program to implement and enforce Federal
section 112 rules as promulgated without changes (straight delegation)
for part 70 sources, a State must demonstrate that it meets the
criteria of 40 CFR 63.91(d). 40 CFR 63.91(d)(3) provides that interim
or final Title V program approval will satisfy the criteria of 40 CFR
63.91(d).\1\ The NESHAP delegation for Louisiana, as it applies to both
part 70 and non-part 70 sources, was most recently approved on February
24, 2015 (80 FR 9613).
---------------------------------------------------------------------------
\1\ Some NESHAP standards do not require a source to obtain a
Title V permit (e.g., certain area sources that are exempt from the
requirement to obtain a Title V permit). For these non-Title V
sources, the EPA believes that the State must assure the EPA that it
can implement and enforce the NESHAP for such sources. See 65 FR
55810, 55813 (September 14, 2000). The EPA previously approved
Louisiana's program to implement and enforce the NESHAP as they
apply to non-part 70 sources. See 69 FR 15687 (March 26, 2004).
---------------------------------------------------------------------------
[[Page 26484]]
IV. How did LDEQ meet the NSPS and NESHAP program approval criteria?
As to the NSPS standards in 40 CFR part 60, LDEQ adopted the
Federal standards via incorporation by reference. The LDEQ regulations
are, therefore, at least as stringent as EPA's rules. See 40 CFR
60.10(a). Also, in the EPA initial approval of NSPS delegation, we
determined that the State developed procedures for implementing and
enforcing the NSPS in the State, and that the State's regulations and
resources are adequate for the implementation and enforcement of the
NSPS program. See 47 FR 7665 (February 22, 1982).
As to the NESHAP standards in 40 CFR parts 61 and 63, as part of
its Title V submission LDEQ stated that it intended to use the
mechanism of incorporation by reference to adopt unchanged Federal
section 112 standards into its regulations. This commitment applied to
both existing and future standards as they applied to part 70 sources.
The EPA's final interim approval of Louisiana's Title V operating
permits program delegated the authority to implement certain NESHAP to
the State. See 60 FR 17750 (April 7, 1995). EPA promulgated final full
approval of the State's operating permits program, on September 12,
1995. See 60 FR 47296. These interim and final Title V program
approvals satisfy the up-front approval criteria of 40 CFR 63.91(d).
Under 40 CFR 63.91(d)(2), once a State has satisfied up-front approval
criteria, it needs only to reference the previous demonstration and
reaffirm that it still meets the criteria for any subsequent submittals
for delegation of the section 112 standards. LDEQ has affirmed that it
still meets the up-front approval criteria. With respect to non-part 70
sources, the EPA has previously approved delegation of NESHAP
authorities to LDEQ after finding adequate authorities to implement and
enforce the NESHAP for such sources. See 69 FR 15687 (March 26, 2004).
V. What is being delegated?
By letter dated September 9, 2022, the EPA received a request from
LDEQ to update its existing NSPS and NESHAP delegations. With certain
exceptions noted in section VI of this document, LDEQ's request
included NSPS in 40 CFR part 60, and NESHAP in 40 CFR parts 61 and 63.
LDEQ's request included newly incorporated NSPS and NESHAP promulgated
by the EPA and amendments to existing standards currently delegated, as
amended between July 1, 2013, and July 1, 2021, as adopted by the
State.
VI. What is not being delegated?
The following part 60, 61 and 63 authorities listed below are not
delegated. All of the inquiries and requests concerning implementation
and enforcement of the excluded standards in the State of Louisiana
should be directed to the EPA Region 6 Office.
<bullet> 40 CFR part 60, subpart AAA (Standards of Performance for
New Residential Wood Heaters);
<bullet> 40 CFR part 61, subpart B (National Emission Standards for
Radon Emissions from Underground Uranium Mines);
<bullet> 40 CFR part 61, subpart H (National Emission Standards for
Emissions of Radionuclides Other Than Radon From Department of Energy
Facilities);
<bullet> 40 CFR part 61, subpart I (National Emission Standards for
Radionuclide Emissions from Federal Facilities Other Than Nuclear
Regulatory Commission Licensees and Not Covered by Subpart H);
<bullet> 40 CFR part 61, subpart K (National Emission Standards for
Radionuclide Emissions from Elemental Phosphorus Plants);
<bullet> 40 CFR part 61, subpart Q (National Emission Standards for
Radon Emissions from Department of Energy facilities);
<bullet> 40 CFR part 61, subpart R (National Emission Standards for
Radon Emissions from Phosphogypsum Stacks);
<bullet> 40 CFR part 61, subpart T (National Emission Standards for
Radon Emissions from the Disposal of Uranium Mill Tailings); and
<bullet> 40 CFR part 61, subpart W (National Emission Standards for
Radon Emissions from Operating Mill Tailings).
In addition, the EPA regulations provide that we cannot delegate to
a State any of the Category II Subpart A authorities set forth in 40
CFR 63.91(g)(2). These include the following provisions: Sec. 63.6(g),
Approval of Alternative Non-Opacity Standards; Sec. 63.6(h)(9),
Approval of Alternative Opacity Standards; Sec. 63.7(e)(2)(ii) and
(f), Approval of Major Alternatives to Test Methods; Sec. 63.8(f),
Approval of Major Alternatives to Monitoring; and Sec. 63.10(f),
Approval of Major Alternatives to Recordkeeping and Reporting. Also,
some parts 61 and 63 standards have certain provisions that cannot be
delegated to the States. Furthermore, no authorities are delegated that
require rulemaking in the Federal Register to implement, or where
Federal overview is the only way to ensure national consistency in the
application of the standards or requirements of CAA section 112.
Finally, this action does not propose delegation of any authority under
section 112(r), the accidental release program.
If this action is finalized as proposed, all questions concerning
implementation and enforcement of the excluded standards in the State
of Louisiana should be directed to the EPA Region 6 Office.
The EPA is proposing a determination that the NESHAP program
submitted by Louisiana meets the applicable requirements of CAA section
112(l)(5) and 40 CFR part 63, subpart E.
In addition, this delegation to LDEQ to implement and enforce
certain NSPS and NESHAP does not extend to sources or activities
located in Indian country, as defined in 18 U.S.C. 1151. Under this
definition, EPA treats as reservations, trust lands validly set aside
for the use of a Tribe even if the trust lands have not been formally
designated as a reservation. Consistent with previous federal program
approvals or delegations, EPA will continue to implement the NSPS and
NESHAP in Indian country because LDEQ has not submitted information to
demonstrate authority over sources and activities located within the
exterior boundaries of Indian reservations and other areas in Indian
country.
VII. How will statutory and regulatory interpretations be made?
If this NSPS delegation update is finalized as proposed, LDEQ will
obtain concurrence from the EPA on any matter involving the
interpretation of section 111 of the CAA or 40 CFR part 60 to the
extent that application, implementation, administration, or enforcement
of these sections have not been covered by prior EPA determinations or
guidance.
If this NESHAP delegation update is finalized as proposed, LDEQ
will obtain concurrence from the EPA on any matter involving the
interpretation of section 112 of the CAA or 40 CFR parts 61 and 63 to
the extent that application, implementation, administration, or
enforcement of these provisions have not been covered by prior EPA
determinations or guidance.
VIII. What authority does the EPA have?
We retain the right, as provided by CAA section 111(c)(2), to
enforce any applicable emission standard or requirement under section
111.
We retain the right, as provided by CAA section 112(l)(7) and 40
CFR 63.90(d)(2), to enforce any applicable
[[Page 26485]]
emission standard or requirement under section 112. In addition, the
EPA may enforce any federally approved State rule, requirement, or
program under 40 CFR 63.90(e) and 63.91(c)(1)(i). The EPA also has the
authority to make certain decisions under the General Provisions
(subpart A) of parts 61 and 63. We are proposing to delegate to the
LDEQ some of these authorities, and retaining others, as explained in
sections V and VI above. In addition, the EPA may review and disapprove
State determinations and subsequently require corrections. See 40 CFR
63.91(g)(1)(ii). The EPA also has the authority to review LDEQ's
implementation and enforcement of approved rules or programs and to
withdraw approval if we find inadequate implementation or enforcement.
See 40 CFR 63.96.
Furthermore, we retain the authority in an individual emission
standard that may not be delegated according to provisions of the
standard. Finally, we retain the authorities stated in the original
delegation agreement. See 47 FR 7665 (February 22, 1982). A table of
currently delegated NSPS and NESHAP standards and how the updated NSPS
and NESHAP delegations would look if this proposal is finalized may be
found in the Technical Support Document (TSD) included in the docket
for this action. The tables also show the authorities that cannot be
delegated to any State or local agency.
IX. What information must LDEQ provide to the EPA?
Under 40 CFR 60.4(b), all notifications under NSPS must be sent to
both EPA and to LDEQ. Notifications and reports should be sent to
Manager, Air Enforcement Branch, at the EPA Region 6 office.
LDEQ must provide any additional compliance related information to
the EPA, Region 6, Office of Enforcement and Compliance Assurance,
within 45 days of a request under 40 CFR 63.96(a). Under 40 CFR.
63.91(g)(1), Louisiana may request delegation any of the authorities
listed as Category I in 40 CFR. 63.91(g)(1)(i), and EPA will delegate
any such authorities at its discretion. The State must maintain a
record of all approved alternatives to all monitoring, testing,
recordkeeping, and reporting requirements and provide this list of
alternatives to its EPA Regional Office at least semi-annually, or on a
more frequent basis if requested by the Regional Office. See 40 CFR.
63.91(g)(1)(ii).
X. What is the EPA's oversight role?
The EPA must oversee LDEQ's decisions to ensure the delegated
authorities are being adequately implemented and enforced. We will
integrate oversight of the delegated authorities into the existing
mechanisms and resources for oversight currently in place. If, during
oversight, we determine that LDEQ has made decisions that decrease the
stringency of the delegated standards, then LDEQ shall be required to
take corrective actions and the source(s) affected by the decisions
will be notified, as required by and under the procedures set forth at
40 CFR 63.96(b). We will initiate withdrawal proceedings of the program
or rule under 40 CFR 63.96(b) if the corrective actions taken are
insufficient.
XI. Should sources submit notices to the EPA or LDEQ?
For the delegated NSPS and NESHAP standards and authorities covered
by this proposed action, if finalized, sources would submit all of the
information required pursuant to the general provisions and the
relevant subpart(s) of the delegated NSPS and NESHAP (40 CFR parts 60,
61 and 63) directly via electronic submittal to online EPA database
portals that are specified in each rule, and also as paper submittals
to the LDEQ at the following address: Louisiana Department of
Environmental Quality, P.O. Box 4301, Baton Rouge, Louisiana 70821-
4301. The LDEQ is the primary point of contact with respect to
delegated NSPS and NESHAP. The EPA Region 6 proposes to waive the
requirement that courtesy notifications and reports for delegated
standards be submitted to the EPA in addition to LDEQ in accordance
with 40 CFR 63.9(a)(4)(ii) and 63.10(a)(4)(ii).\2\ For those standards
and authorities not delegated as discussed above, sources must continue
to submit all appropriate information to the EPA by electronic database
portals.
---------------------------------------------------------------------------
\2\ This waiver only extends to the submission of copies of
notifications and reports; the EPA does not waive the requirements
in delegated standards that require notifications and reports be
submitted to an electronic database (e.g., 40 CFR part 63, subpart
HHHHHHH).
---------------------------------------------------------------------------
XII. How will unchanged authorities be delegated to LDEQ in the future?
In the future, LDEQ will only need to send a letter of request to
update their delegation to EPA, Region 6, for those NSPS which they
have adopted by reference. EPA will amend the relevant portions of the
Code of Federal Regulations showing which NSPS standards have been
delegated to LDEQ. Also, in the future, LDEQ will only need to send a
letter of request for approval to EPA, Region 6, for those specific
NESHAP regulations that LDEQ has incorporated by reference into State
rules. The letter must reference the previous up-front approval
demonstration and reaffirm that it still meets the up-front approval
criteria. We will respond in writing to the request stating that the
request for delegation is either granted or denied. A Federal Register
action will be published to inform the public and affected sources of
the delegation, indicate where source notifications and reports should
be sent, and to amend the relevant portions of the Code of Federal
Regulations showing which NESHAP standards have been delegated to LDEQ.
XIII. Proposed Action
In this action, the EPA is proposing to update the delegation of
certain NSPS to LDEQ, and to approve an update to the Louisiana NESHAP
delegation that would provide the LDEQ with the authority to implement
and enforce certain newly incorporated NESHAP promulgated by the EPA
and amendments to existing standards currently delegated, as they
existed though July 1, 2021.
XIV. Statutory and Executive Order Reviews
Under the CAA, the Administrator has the authority to approve
section 112(l) submissions that comply with the provisions of the Act
and applicable Federal regulations. In reviewing section 112(l)
submissions, the EPA's role is to approve State choices, provided that
they meet the criteria and objectives of the CAA and of the EPA's
implementing regulations. Accordingly, this proposed action would
merely approve the State's request as meeting Federal requirements and
does not impose additional requirements beyond those imposed by State
law. For that reason, this proposed action:
A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 13563: Improving Regulation and Regulatory Review
This action is not a significant regulatory action as defined in
Executive Order 12866 (58 FR 51735, October 4, 1993) and was therefore
not submitted to the Office of Management and Budget (OMB) for review.
B. Executive Order 14192: Unleashing Prosperity Through Deregulation
This action is not an Executive Order 14192 regulatory action
because this action is not significant under Executive Order 12866.
[[Page 26486]]
C. Paperwork Reduction Act (PRA)
This action does not impose an information collection burden under
the PRA (44 U.S.C. 3501 et seq.) because it does not impose an
information collection burden.
D. Regulatory Flexibility Act (RFA)
This action is certified to not have a significant economic impact
on a substantial number of small entities under the RFA (5 U.S.C. 601
et seq.). This action proposes to approve the delegation of federal
rules as requested by the state agency and will therefore have no net
regulatory burden for all directly regulated small entities.
E. Unfunded Mandates Reform Act (UMRA)
This action does not contain an unfunded mandate as described in
UMRA, 2 U.S.C 1531-1538, and does not significantly or uniquely affect
small governments. This action imposes no enforceable duty on any
State, local, or tribal governments or the private sector.
F. Executive Order 13132: Federalism
This action does not have federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999). 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.
G. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
This proposal to update the delegation of certain NSPS to LDEQ and
to approve LDEQ's request to update their NESHAP delegation will not
apply in areas of Indian Country, and therefore has no tribal
implications as specified in Executive Order 13175 (65 FR 67249,
November 9, 2000). This action will neither impose substantial direct
compliance costs on federally recognized tribal governments, nor
preempt tribal law. This action will not impose substantial direct
compliance costs on federally recognized tribal governments because no
actions will be required of tribal governments. This action will also
not preempt tribal law as no Louisiana tribe implements a regulatory
program under the CAA, and thus does not have applicable or related
tribal laws.
H. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks
The EPA interprets Executive Order 13045 as applying only to
regulatory actions considered significant under section 3(f)(1) of
Executive Order 12866 and that concern environmental health or safety
risks that EPA has reason to believe may disproportionately affect
children, per the definition of ``covered regulatory action'' in
section 2-202 of Executive Order 13045. This action is not subject to
Executive Order 13045 because it approves a state program.
I. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution or Use
This action is not subject to Executive Order 13211 (66 FR 28355,
May 22, 2001), because it is not a significant regulatory action under
Executive Order 12866.
J. National Technology Transfer and Advancement Act (NTTAA)
This rulemaking does not involve technical standards. This action
is not subject to requirements of section 12(d) of the National
Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note)
because application of those requirements would be inconsistent with
the Clean Air Act.
