Wyoming: Final Authorization of State Hazardous Waste Management 
Program Revisions and Incorporation by Reference

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

-----------------------------------------------------------------------

SUMMARY: The State of Wyoming Department of Environmental Quality has 
applied to the Environmental Protection Agency (EPA) for final 
authorization of the changes to its hazardous waste program under the 
Resource Conservation and Recovery Act (RCRA). The EPA has determined 
that these changes satisfy all requirements needed to qualify for final 
authorization and is authorizing the State's changes through this 
direct final action. The EPA uses the regulations entitled ``Approved 
State Hazardous Waste Management Programs'' to provide notice of the 
authorization status of State programs and to incorporate by reference 
those provisions of State statutes and regulations that will be subject 
to the EPA's inspection and enforcement. This rule also codifies in the 
regulations the approval of Wyoming's hazardous waste management 
program and incorporates by reference authorized provisions of the 
State's regulations.

DATES: This direct final rule is effective on November 24, 2023 unless 
the EPA receives adverse written comment by October 25, 2023. If the 
EPA receives any such comment, we will publish a timely withdrawal of 
this direct final rule in the Federal Register informing the public 
that the rule will not take effect. The Director of the Federal 
Register approves the incorporation by reference as of November 24, 
2023, in accordance with 5 U.S.C. 552(a) and 1 CFR part 51.

SUPPLEMENTARY INFORMATION:

I. Authorization of Revisions to Wyoming's Hazardous Waste Program

A. Why are revisions to State programs necessary?

    States which have received final authorization from the EPA under 
RCRA section 3006(b), 42 U.S.C. 6926(b), must maintain a hazardous 
waste program that is equivalent to, consistent with, and no less 
stringent than the Federal program. As the Federal program changes, 
States must change their programs and ask the EPA to authorize the 
changes. Changes to State programs may be necessary when Federal or 
State statutory or regulatory authority is modified or when certain 
other changes occur. Most commonly, States must change their programs 
because of changes to the EPA's regulations in 40 Code of Federal 
Regulations (CFR) parts 124, 260 through 268, 270, 273 and 279.

B. What authorization decisions has the EPA made in this rule?

    On June 17, 2022, Wyoming submitted a program revision application 
seeking authorization of changes to its hazardous waste program. The 
EPA concludes that Wyoming's applications to revise its authorized 
program meet all of the statutory and regulatory requirements 
established by RCRA. Therefore, we grant Wyoming final authorization to 
operate its hazardous waste program with the changes described in the 
authorization application. Wyoming has responsibility for permitting 
Treatment, Storage, and Disposal Facilities (TSDFs), and for carrying 
out the aspects of the RCRA program described in its revised program 
application, subject to the limitations of the Hazardous and Solid 
Waste Amendments of 1984 (HSWA), for all areas within the State, except 
for (1) lands located within formal Indian Reservations within or 
abutting the State of Wyoming, including Wind River Indian Reservation, 
(2) any land held in trust by the United States for an Indian tribe, 
(3) and any other land,

[[Page 65622]]

whether on or off a reservation that qualifies as ``Indian country'' 
within the meaning of 18 U.S.C. 1151. New Federal requirements and 
prohibitions imposed by Federal regulations that the EPA promulgates 
under the authority of HSWA take effect in authorized States before 
they are authorized for the requirements. Thus, the EPA will implement 
those requirements and prohibitions in Wyoming, including issuing 
permits, until Wyoming is authorized to do so.

C. What is the effect of today's authorization decision?

    The effect of this decision is that a facility in Wyoming subject 
to RCRA will have to comply with the authorized State requirements 
instead of the equivalent Federal requirements in order to comply with 
RCRA. The State of Wyoming will continue to have enforcement 
responsibilities under its State hazardous waste program for violations 
of such program, but the EPA retains its authority under RCRA sections 
3007, 3008, 3013, and 7003, which include, among others, authority to:
     Conduct inspections and require monitoring, tests, 
analyses, or reports;
     Enforce RCRA requirements; suspend or revoke permits; and
     Take enforcement actions after notice to and consultation 
with the State.
    This action to approve these provisions would not impose additional 
requirements on the regulated community because the regulations for 
which the State of Wyoming is requesting authorization are already 
effective under State law and are not changed by the act of 
authorization.

D. Why is the EPA using a direct final rule?

    The EPA is publishing this rule without a prior proposal because we 
view this as a noncontroversial action and anticipate no adverse 
comment. However, in the ``Proposed Rules'' section of this issue of 
the Federal Register, we are publishing a separate document that will 
serve as the proposed rule allowing the public an opportunity to 
comment. We will not institute a second comment period on this action. 
Any parties interested in commenting must do so at this time. For 
further information about commenting on this rule, see the ADDRESSES 
section of this document.

E. What happens if the EPA receives comments opposing this action?

    If the EPA receives comments that oppose this authorization, we 
will publish a timely withdrawal in the Federal Register informing the 
public that this direct final rule will not take effect. We will 
address all public comments in a later Federal Register document. You 
will not have another opportunity to comment, therefore, if you want to 
comment on this action, you must do so at this time.

F. For what has Wyoming previously been authorized?

    Wyoming initially received Final authorization on October 4, 1995, 
effective October 18, 1995 (60 FR 51925) to implement the RCRA 
hazardous waste management program. We granted authorization for 
changes to their program on: February 25, 1999, effective August 6, 
2001 (56 FR 15503); however, this authorization was subsequently 
withdrawn on April 23, 1999 (64 FR 19925) and re-issued with the 
initial effective date of August 6, 2001 (66 FR 40911). Most recently, 
the EPA granted authorization for changes to Wyoming's program on June 
24, 2016, effective August 23, 2016 (81 FR 41229).

G. What changes is the EPA authorizing with this action?

    On June 17, 2022, the State of Wyoming submitted a program revision 
application seeking authorization of their changes in accordance with 
40 CFR 271.21. We now make a final decision, subject to receipt of 
written comments that oppose this action, that Wyoming's hazardous 
waste program satisfies all of the requirements necessary to qualify 
for final authorization. Therefore, we grant Wyoming final 
authorization for the following changes:
1. Program Revision Changes for Federal Rules

2. State-Initiated Changes
    Wyoming has made amendments to its regulations that are not 
directly related to any of the Federal rules addressed in Item G.1 
above. These State-initiated changes are either conforming changes made 
to existing authorized provisions, or the adoption of provisions that 
clarify and make the State's regulations internally consistent. The 
State's regulations, as amended by these provisions, provide authority 
which remains equivalent to and no less stringent than the Federal laws 
and regulations. These State-initiated changes are submitted under the 
requirements of 40 CFR 271.21(a) and include the following provisions 
from the Hazardous Waste Rules and Regulations (HWRR), Chapter 1, as 
amended, effective April 7, 2022: HWRR 2(c), 3(b) ``Administrator'' or 
``Regional Administrator'', 3(c) ``Board'' or ``Environmental Appeals 
Board'', 3(g) ``Qualified Professional Geologist'', 3(h) ``RCRA'', 3(k) 
``United States'' or ``U.S.'', 4(a) ``Air contaminant'', 4(b) ``Air 
pollution'', 4(u) ``One excess cancer per million people'', 4(v) 
``Potentially exposed populations'', 4(z) ``Waste material'', 
260(a)(i), 260(a)(ii), 264(a)(iv), 264(d)(iii) introductory paragraph, 
264(h)(i) introductory paragraph, (A) and (B), 264(i)(viii), 264(j), 
265(b), 266(b)(iv), 267(a), 270(a)(iv), and 270(a)(xviii).

H. Where are the revised State rules different from the Federal rules?

    The Wyoming revisions being authorized in this rule include 
provisions that contain purely Federal functions which are not 
delegable to States. The non-delegable Federal program areas include 
import/export requirements reserved as part of the Federal foreign 
relations function, and manifest registry and electronic manifest 
functions administered solely by the EPA. Wyoming has appropriately 
adopted these provisions by leaving the authority with the EPA for 
implementation and enforcement.
    When revised State rules differ from the Federal rules in the RCRA 
State authorization process, the EPA determines whether the State rules 
are equivalent to, more stringent than, or broader in scope than the 
Federal program. Pursuant to RCRA section 3009, 42 U.S.C. 6929, State 
programs may contain requirements that are more stringent than the 
Federal regulations. Such more stringent requirements can be federally 
authorized and, once authorized, become federally enforceable. Although 
the statute does not prevent States from adopting regulations that are 
broader in scope than the Federal program, States cannot receive 
Federal authorization for such regulations, and they are not federally 
enforceable.
    We consider the following State requirements to be more stringent 
than the Federal requirements: HWRR, Chapter 1, Sections 3(f), 3(g), 
261(a)(iii), 261(b), 262(d), and 262(f), for the following reasons.
    At Sections 3(f) and 3(g), Wyoming requires both professional 
engineers and professional geologists to be registered in the State 
when referring to activities requiring Professional Engineer or 
Professional Geologist certification.
    At 261(a)(iii), 262(a)(v), 262(d), and 262(f), Wyoming requires 
copies of necessary notifications and reports be made and submitted to 
the Director or State agency in addition to the required Federal 
notification or reporting.
    The State did not make any changes that are broader-in-scope than 
the Federal rules in this rulemaking. In addition, Wyoming did not 
change any previously more stringent or broader-in-scope provisions to 
be equivalent to the Federal rules.

I. Who handles permits after the authorization takes effect?

    The State of Wyoming will continue to issue permits for all the 
provisions for which it is authorized and will administer the permits 
it issues. The EPA will continue to administer any RCRA hazardous waste 
permits or portions of permits which we issued prior to the effective 
date of this authorization, until Wyoming has equivalent instruments in 
place. The EPA will implement and issue permits for HSWA requirements 
for which Wyoming is not yet authorized.

J. How does today's action affect Indian Country (18 U.S.C.1151) in 
Wyoming?

    Wyoming is not authorized to carry out its hazardous waste program 
in Indian country, as defined in 18 U.S.C. 1151. This includes, but is 
not limited to:
    1. Lands within the exterior boundaries of the following Indian

[[Page 65624]]

Reservations located within or abutting the State of Wyoming:
    a. Wind River Indian Reservation
    2. Any land held in trust by the U.S. for an Indian tribe; and
    3. Any other land, whether on or off a reservation that qualifies 
as Indian country within the meaning of 18 U.S.C. 1151.
    Therefore, this program revision does not extend to Indian country 
where the EPA will continue to implement and administer the RCRA 
program.

II. Incorporation by Reference

    Codification is the process of including the statutes and 
regulations that comprise the State's authorized hazardous waste 
management program into the CFR. Section 3006(b) of RCRA, as amended, 
allows the Environmental Protection Agency (EPA) to authorize State 
hazardous waste management programs. The EPA is incorporating by 
reference EPA's approval of Wyoming's hazardous waste management 
program by amending Subpart ZZ to 40 CFR part 272. The action amends 
Sec.  272.2551 and incorporates by reference Wyoming's authorized 
hazardous waste regulations, as amended effective April 7, 2022. The 
State regulations authorized by EPA supplant the Federal regulations 
concerning the same matter with the result that after authorization EPA 
enforces the authorized regulations as described in paragraphs I. and 
II in this Supplementary Information. The EPA has made these documents 
available electronically through https://www.regulations.gov and will 
continue to make these documents available. For alternative access to 
docket materials, please contact the person identified in the ADDRESSES 
section of this preamble.

III. Administrative Requirements

    The Office of Management and Budget (OMB) has exempted this action 
from the requirements of Executive Orders 12866 (58 FR 51735, October 
4, 1993) and 13563 (76 FR 3821, January 21, 2011). Therefore, this 
action is not subject to review by OMB. This action authorizes and 
codifies State requirements for the purpose of RCRA 3006 and imposes no 
additional requirements beyond those imposed by State law. Accordingly, 
I certify that this action will not have a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.). Because this action authorizes 
and codifies pre-existing requirements under State law and does not 
impose any additional enforceable duty beyond that required by State 
law, it does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4). For the same reason, this 
action also does not significantly or uniquely affect the communities 
of Tribal governments, as specified by Executive Order 13175 (65 FR 
67249, November 9, 2000). This action 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, as specified 
in Executive Order 13132 (64 FR 43255, August 10, 1999), because it 
merely authorizes and codifies State requirements as part of the State 
RCRA hazardous waste program without altering the relationship or the 
distribution of power and responsibilities established by RCRA.
    This action also is not subject to Executive Order 13045 (62 FR 
19885, April 23, 1997), because it is not economically significant, and 
it does not make decisions based on environmental health or safety 
risks. This rule is not subject to Executive Order 13211, ``Actions 
Concerning Regulations That Significantly Affect Energy Supply, 
Distribution, or Use'' (66 FR 28355, May 22, 2001), because it is not a 
significant regulatory action under Executive Order 12866.
    Under RCRA 3006(b), the EPA grants a State's application for 
authorization as long as the State meets the criteria required by RCRA. 
It would thus be inconsistent with applicable law for the EPA, when it 
reviews a State authorization application, to require the use of any 
particular voluntary consensus standard in place of another standard 
that otherwise satisfies the requirements of RCRA. Thus, the 
requirements of section 12(d) of the National Technology Transfer and 
Advancement Act of 1995 (15 U.S.C. 272 note) do not apply. As required 
by section 3 of Executive Order 12988 (61 FR 4729, February 7, 1996), 
in issuing this rule, the EPA has taken the necessary steps to 
eliminate drafting errors and ambiguity, minimize potential litigation, 
and provide a clear legal standard for affected conduct. The EPA has 
complied with Executive Order 12630 (53 FR 8859, March 15, 1988) by 
examining the takings implications of the rule in accordance with the 
``Attorney General's Supplemental Guidelines for the Evaluation of Risk 
and Avoidance of Unanticipated Takings'' issued under the executive 
order. This rule does not impose an information collection burden under 
the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 
et seq.).
    Executive Order 12898 (59 FR 7629, February 16, 1994) establishes 
federal executive policy on environmental justice. Its main provision 
directs federal agencies, to the greatest extent practicable and 
permitted by law, to make environmental justice part of their mission 
by identifying and addressing, as appropriate, disproportionately high 
and adverse human health or environmental effects of their programs, 
policies, and activities on minority populations and low-income 
populations in the United States. Because this rule authorizes pre-
existing State rules which are at least equivalent to, and no less 
stringent than existing Federal requirements and imposes no additional 
requirements beyond those imposed by State law, and there are no 
anticipated significant adverse human health or environmental effects, 
the rule is not subject to Executive Order 12898.
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. The EPA will submit a report containing this document 
and other required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication in the Federal Register. A major rule cannot take effect 
until 60 days after it is published in the Federal Register. This 
action is not a ``major rule'' as defined by 5 U.S.C. 804(2). This 
action will be effective November 24, 2023.

2. Revise Sec.  272.2551 to read as follows:


Sec.  272.2551  Wyoming State-Administered Program: Final 
Authorization.

    (a) History of the State of Wyoming authorization. Pursuant to 
section 3006(b) of RCRA, 42 U.S.C. 6926(b), Wyoming has final 
authorization for the following elements as submitted to the EPA in 
Wyoming's base program application for final authorization which was 
approved by the EPA effective on October 18, 1995. Subsequent program 
revision applications were approved effective on August 6, 2001, August 
23, 2016, and November 24, 2023.
    (b) Enforcement authority. The State of Wyoming has primary 
responsibility for enforcing its hazardous waste management program. 
However, the EPA retains the authority to exercise its inspection and 
enforcement authorities in accordance with sections 3007, 3008, 3013, 
7003 of RCRA, 42 U.S.C. 6927, 6928, 6934, 6973, and any other 
applicable statutory and regulatory provisions, regardless of whether 
the State has taken its own actions, as well as in accordance with 
other statutory and regulatory provisions.
    (c) State Statutes and Regulations--(1) Incorporation by reference. 
The Wyoming regulations cited in paragraph (c)(1)(i) of this section 
are incorporated by reference as part of the hazardous waste management 
program under Subtitle C of RCRA, 42 U.S.C. 6921 et seq. The Director 
of the Federal Register approves this incorporation by reference in 
accordance with 5 U.S.C. 552(a) and 1 CFR part 51. For the availability 
of this information at the National Archives and Records Administration 
(NARA) and at the EPA, see Sec.  272.2. You may access copies of the

predate HSWA (non-HSWA) which the State has adopted, but for which it 
is not authorized, are not Federally enforceable. In contrast, the EPA 
will continue to enforce the Federal HSWA standards for which Wyoming 
is not authorized until the State receives specific authorization from 
the EPA.
    (5) Memorandum of Agreement. The Memorandum of Agreement between 
the EPA Region 8 and the State of Wyoming, signed by the State of 
Wyoming Department of Environmental Quality on March 7, 2016, and by
