SUPPLEMENTARY INFORMATION:

Authority for This Rulemaking

    The FAA's authority to issue rules regarding aviation safety is
found in Title 49 of the United States Code. Subtitle I, Section 106
describes the authority of the FAA Administrator. Subtitle VII,
Aviation Programs, describes in more detail the scope of the agency's
authority. This rulemaking is promulgated under the authority described
in Subtitle VII, Part A, Subpart I, Section 40103. Under that section,
the FAA is charged with prescribing regulations to assign the use of
airspace necessary to ensure the safety of aircraft and the efficient
use of airspace. This regulation is within the scope of that authority
as it would amend the Class E airspace extending upward from 700 feet
above the surface at Sulphur Springs Municipal Airport, Sulphur
Springs, TX, to support instrument flight rule operations at this
airport.

Comments Invited

    Interested parties are invited to participate in this proposed
rulemaking by submitting such written data, views, or arguments, as
they may desire. Comments that provide the factual basis supporting the
views and suggestions presented are particularly helpful in developing
reasoned regulatory decisions on the proposal. Comments are
specifically invited on the overall regulatory, aeronautical, economic,
environmental, and energy-related aspects of the proposal.
Communications should identify both docket numbers and be submitted in
triplicate to the address listed above. Commenters wishing the FAA to
acknowledge receipt of their comments on this notice must submit with
those comments a self-addressed, stamped postcard on which the
following statement is made: ``Comments to Docket No. FAA-2023-0037/
Airspace Docket No. 23-ASW-1.'' The postcard will be date/time stamped
and returned to the commenter.
    All communications received before the specified closing date for
comments will be considered before taking action on the proposed rule.
The proposal contained in this notice may be changed in light of the
comments received. A report summarizing each substantive public contact
with FAA personnel concerned with this rulemaking will be filed in the

Availability and Summary of Documents for Incorporation by Reference

    This document proposes to amend FAA Order JO 7400.11G, Airspace
Designations and Reporting Points, dated August 19, 2022, and effective
September 15, 2022. FAA Order JO 7400.11G is publicly available as
listed in the ADDRESSES section of this document. FAA Order JO 7400.11G
lists Class A, B, C, D, and E airspace areas, air traffic service
routes, and reporting points.

The Proposal

    The FAA is proposing an amendment to 14 CFR part 71 by amending the
Class E airspace extending upward from 700 feet above the surface at
Sulphur Springs Municipal Airport, Sulphur Springs, TX, by removing the
Brashear radio beacon (RBN) and associated airspace extension as they
are no longer needed; and adding an extension 2 miles each side of the
190[deg] bearing from the airport extending from the 6.5-mile radius of
the airport to 9.4 miles south of the airport.
    This action is the result of an airspace review conducted as part
of the decommissioning of the Sulphur Springs VOR, which provided
navigation information to the instrument procedures to this airport, as
part of the VOR MON Program.
    Class E airspace designations are published in paragraph 6005 of
FAA Order JO 7400.11G, dated August 19, 2022, and effective September
15, 2022, which is incorporated by reference in 14 CFR 71.1. The Class
E airspace designations listed in this document will be published
subsequently in FAA Order JO 7400.11.
    FAA Order JO 7400.11, Airspace Designations and Reporting Points,
is published yearly and effective on September 15.

Regulatory Notices and Analyses

    The FAA has determined that this regulation only involves an
established body of technical regulations for which frequent and
routine amendments are necessary to keep them operationally current, is
non-controversial and unlikely to result in adverse or negative
comments. It, therefore: (1) is not a ``significant regulatory action''
under Executive Order 12866; (2) is not a ``significant rule'' under
DOT Regulatory Policies and Procedures (44 FR 11034; February 26,
1979); and (3) does not warrant preparation of a regulatory evaluation
as the anticipated impact is so minimal. Since this is a routine matter
that will only affect air traffic procedures and air navigation, it is
certified that this rule, when promulgated, would not have a
significant economic impact on a substantial number of small entities
under the criteria of the Regulatory Flexibility Act.

Environmental Review

    This proposal will be subject to an environmental analysis in
accordance with FAA Order 1050.1F, ``Environmental Impacts: Policies
and Procedures'' prior to any FAA final regulatory action.

40 CFR Part 271

[EPA-R03-RCRA-2014-0407; FRL-9965-87-Region 3]

Delaware: Final Authorization of State Hazardous Waste Management
Program Revisions

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: Delaware has applied to the United States Environmental
Protection Agency (EPA) for final authorization of revisions to its
hazardous waste program under the Resource Conservation and Recovery
Act (RCRA). EPA has determined that these revisions satisfy all
requirements needed to qualify for final authorization and is
authorizing Delaware's revisions through this direct final rule. In the
``Proposed Rules'' section of this issue of the Federal Register, EPA
is also publishing a separate document that serves as the proposal to
authorize these revisions. EPA believes this action is not
controversial and does not expect comments that oppose it. Unless EPA
receives written comments that oppose this authorization during the
comment period, the decision to authorize Delaware's revisions to its
hazardous waste program will take effect. If EPA receives comments that
oppose this action, EPA will publish a document in the Federal Register
withdrawing this direct final rule before it takes effect and the
separate document in the ``Proposed Rules'' section of this issue of
the Federal Register will serve as the proposal to authorize the
revisions.

DATES: This final authorization will become effective on October 10,
2017, unless EPA receives adverse written comments by September 11,
2017. If EPA receives any such comments, EPA will publish a timely
withdrawal of this direct final rule in the Federal Register and inform
the public that this authorization will not take effect.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R03-
RCRA-2014-0407, at http://www.regulations.gov. Follow the online
instructions for submitting comments. Once submitted, comments cannot
be edited or removed from Regulations.gov. The EPA may publish any
comment received to its public docket. Do not submit electronically any
information you consider to be Confidential Business Information (CBI)
or other information whose disclosure is restricted by statute.
Multimedia submissions (audio, video, etc.) must be accompanied by a
written comment. The written comment is considered the official comment
and should include discussion of all points you wish to make. The EPA
will generally not consider comments or comment contents located
outside of the primary submission (i.e., on the web, cloud, or other
file sharing system). For additional submission methods, the full EPA
public comment policy, information about CBI or multimedia submissions,
and general guidance on making effective comments, please visit http://www2.epa.gov/dockets/commenting-epa-dockets.

RCRA Waste Branch, Mailcode 3LC32, 1650 Arch Street, Philadelphia, PA
19103-2029; Phone:<PHONE_NUMBER>; Email<EMAIL_ADDRESS>
SUPPLEMENTARY INFORMATION:

A. Why are revisions to State programs necessary?

    States that have received final authorization from 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 is revised to become
more stringent or broader in scope, States must revise their programs
and apply to EPA to authorize the revisions. Authorization of revisions
to State programs may be necessary when Federal or State statutory or
regulatory authority is modified or when certain other revisions occur.
Most commonly, States must revise their programs because of revisions
to EPA's regulations in 40 Code of Federal Regulations (CFR) parts 124,
260 through 266, 268, 270, 273 and 279.

B. What decisions has EPA made in this rule?

    On August 19, 2016, Delaware submitted a final program revision
application (with subsequent corrections) seeking authorization of
revisions to its hazardous waste program that correspond to certain
Federal rules promulgated between July 30, 2003 and July 28, 2006. EPA
concludes that Delaware's application to revise its authorized program
meets all of the statutory and regulatory requirements established by
RCRA, as set forth in RCRA section 3006(b), 42 U.S.C. 6926(b), and 40
CFR part 271. Therefore, EPA grants Delaware final authorization to
operate its hazardous waste program with the revisions described in its
authorization application, and as outlined below in Section G of this
document.
    Delaware has responsibility for permitting treatment, storage, and
disposal facilities (TSDFs) within its borders and for carrying out the
aspects of the RCRA program described in its application, subject to
the limitations of the Hazardous and Solid Waste Amendments of 1984
(HSWA). New Federal requirements and prohibitions imposed by Federal
regulations that EPA promulgates under the authority of HSWA take
effect in authorized States before they are authorized for the
requirements. Thus, EPA will implement those HSWA requirements and
prohibitions for which Delaware has not been authorized, including
issuing HSWA permits, until the State is granted authorization to do
so.

C. What is the effect of this authorization decision?

    This action serves to authorize revisions to Delaware's authorized
hazardous waste program. This action does not impose additional
requirements on the regulated community because the regulations for
which Delaware is being authorized by this action are already effective
and are not changed by this action. Delaware has enforcement
responsibilities under its state hazardous waste program for violations
of its program, but EPA retains its authority under RCRA sections 3007,
3008, 3013, and 7003, which include, among others, authority to:
     Perform inspections, and require monitoring, tests,
analyses or reports;
     Enforce RCRA requirements and suspend or revoke permits;
and
     Take enforcement actions regardless of whether Delaware
has taken its own actions.

D. Why wasn't there a proposed rule before this rule?

    Along with this direct final rule, EPA is publishing a separate
document in the ``Proposed Rules'' section of this issue of the Federal
Register that serves as the proposal to authorize these State program
revisions. EPA did not publish a proposal before this rule because EPA
views this action as a routine program change and does not expect
comments that oppose its approval. EPA is providing an opportunity for
public comment now, as described in Section E of this document.

E. What happens if EPA receives comments that oppose this action?

    If EPA receives comments that oppose this authorization, EPA will
withdraw this direct final rule by publishing a document in the Federal
Register before the rule becomes effective. EPA will base any further
decision on the authorization of Delaware's program revisions on the
proposal mentioned in the previous section, after considering all
comments received during the comment period. EPA will then address all
such comments in a later final rule. You may not have another
opportunity to comment. If you want to comment on

this authorization, you must do so at this time.
    If EPA receives comments that oppose only the authorization of a
particular revision to the State's hazardous waste program, EPA will
withdraw that part of this rule, but the authorization of the program
revisions that the comments do not oppose will become effective on the
date specified above. The Federal Register withdrawal document will
specify which part of the authorization will become effective, and
which part is being withdrawn.

F. What has Delaware previously been authorized for?

    Delaware initially received final authorization effective June 22,
1984 (June 8, 1984; 49 FR 23837). EPA granted authorization for
revisions to Delaware's regulatory program on August 8, 1996, effective
October 7, 1996 (61 FR 41345); August 18, 1998, effective October 19,
1998 (63 FR 44152); July 12, 2000, effective September 11, 2000 (65 FR
42871); August 8, 2002, effective August 8, 2002 (67 FR 51478); March
4, 2004, effective May 3, 2004 (69 FR 10171); and October 7, 2004,
effective December 6, 2004 (69 FR 60091).

G. What revisions is EPA authorizing with this action?

    On August 19, 2016, Delaware submitted a final program revision
application (with subsequent corrections), seeking authorization of
additional revisions to its program in accordance with 40 CFR 271.21.
Delaware's revision application includes various regulations that are
equivalent to, and no less stringent than, selected Federal final
hazardous waste rules, as published in the Federal Register between
July 30, 2003 and July 28, 2006.
    EPA now makes a direct final rule, subject to receipt of written
comments that oppose this action, that Delaware's hazardous waste
program revision application satisfies all of the requirements
necessary to qualify for final authorization. Therefore, EPA grants
Delaware final authorization for the following program revisions:

1. Program Revision Changes for Federal Rules

    Delaware seeks authority to administer the Federal requirements
that are listed in Table 1 below. This table lists the Delaware analogs
that have been revised; these revisions are being recognized as no less
stringent than the analogous Federal requirements.
    Delaware's regulatory references are to Delaware's Regulations
Governing Hazardous Waste (DRGHW), amended and effective August 21,
2006, December 21, 2007, December 21, 2008, May 21, 2009, and April 21,
2016. Additionally, there are some minor corrections that were
promulgated and became effective on or before April 21, 2016. The
statutory references are to 7 Delaware Code annotated (1991).

\1\ A Revision Checklist is a document that addresses the specific
  revisions made to the Federal regulations by one or more related final
  rules published in the Federal Register. EPA develops these checklists
  as tools to assist States in developing their authorization
  applications and in documenting specific State analogs to the Federal
  regulations. For more information see EPA's RCRA State Authorization
  Web page at https://www.epa.gov/rcra/state-authorization-under-resource-conservation-and-recovery-act-rcra.
\2\ Unless otherwise indicated, all Delaware citations are from the
  state's 2009 regulations. Minor modifications that became effective in
  2016, but for which the exact effective date is unknown are denoted
  with a ``[2016]'' following the regulatory citation.

2. State-Initiated Changes

    Delaware's program revision application includes State-initiated
changes that are not directly related to any of the Revision Checklists
in Table 1. These State-initiated revisions to some of Delaware's
existing regulations are for the purposes of correcting errors and
adding consistency or clarification to the existing regulations. EPA
has evaluated the changes and has determined that the State's
regulations remain consistent with, and are no less stringent than, the
corresponding Federal regulations. EPA grants Delaware final
authorization for the State provisions listed in Table 2. The following
State-initiated revisions are

equivalent and analogous to the numerically identical provisions of the
Federal RCRA regulations found at relevant or applicable 40 CFR
sections as of July 1, 2007.

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

1. Delaware Requirements That Are Broader in Scope

    The Delaware hazardous waste program contains certain provisions
that are broader in scope than the Federal program. These broader in
scope provisions are not part of the program being authorized by this
action. EPA cannot enforce requirements that are broader in scope,
although compliance with such provisions is required by Delaware law.
Examples of broader in scope provisions of Delaware's program include,
but are not limited to, the following:
    (a) DRGHW 260.10 includes the definition of ``cathode ray tube
(CRT) generator,'' which is not found in the Federal regulations.
Furthermore, the definition of ``CRT processing'' found at DRGHW
260.10, and the requirements at DRGHW 261.39, DRGHW 261.40, and DRGHW
261.4(b)(16)(i)-(iii), contain language regarding the management of
cathode ray tubes as a solid waste. Under the Federal requirements,
used CRTs that meet certain conditions are not a solid waste and would
not be regulated. Delaware continues to regulate those used CRTs even
if they meet the Federal exclusion requirements. As a result,
Delaware's regulation of these excluded CRTs goes beyond the scope of
the Federal program and is not a part of the Federally enforceable
program.
    (b) The Delaware regulations promulgated at DRGHW 263 Subpart E
outline provisions for hazardous waste transporter permits. Because
there is no counterpart in the Federal regulations that addresses
hazardous waste transporter permits, this entire section (DRGHW 263
Subpart E) is broader in scope. Delaware has made changes to
subparagraphs 263.102(b)(3) and (4) of DRGHW 263 Subpart E. These
subparagraphs set forth conditions that could lead to the modification,
denial, termination, or revocation of a hazardous waste transporter
permit. There are no provisions in the Federal regulations that address
the modification, denial, termination, or revocation of a hazardous
waste transporter permit. As a result, these DRGHW provisions go beyond
the scope of the Federal program.

2. Delaware Requirements That Are More Stringent Than the Federal
Program

    Delaware's hazardous waste program contains several provisions that
are more stringent than the RCRA program. The more stringent provisions
are part of the Federally-authorized program and are, therefore,
Federally-enforceable. The specific more stringent provisions are also
noted in Table 1 and in Delaware's authorization application. They
include, but are not limited to, the following:
    (a) The Federal regulations at 40 CFR 261.5(j) state that if a
conditionally exempt small quantity generator's wastes are mixed with
used oil, the mixture is subject to the ``Standards for the Management
of Used Oil.'' However, Delaware's regulations at DRGHW 261.5(j) state
that if a conditionally exempt small quantity generator's wastes are
mixed with used oil, the mixture is subject to several standards
including: the Hazardous Waste Management System; Identification and
Listing of Hazardous Waste; Standards Applicable to Generators of
Hazardous Waste; Standards Applicable to Transporters of Hazardous
Waste; Standards for Owners and Operators of Hazardous Waste Treatment,
Storage, and Disposal Facilities; Interim Status Standards for Owners
and Operators of Hazardous Waste Treatment, Storage, and Disposal
Facilities; Standards for the Management of Specific Types of Hazardous
Waste; Land Disposal Restrictions; the Hazardous Waste Permit Program;
and Procedures for Decision Making. Because Delaware imposes additional
standards on waste and used oil mixtures, Delaware's regulations are
more stringent than the Federal requirements.
    (b) DRGHW 261.41 includes more stringent requirements, at DRGHW
261.41(a), which are not found in 40 CFR 261.41. Specifically, the
Delaware provision imposes additional requirements on used, intact
Cathode Ray Tubes (CRTs) exported for reuse. When applied to CRTs that
are regulated by the Federal requirements, the provisions at DRGHW
261.41(a) are more stringent than the Federal requirements.
    (c) The Delaware regulations at DRGHW 262.12(d) require that a
generator submit a ``RCRA Subtitle C Site Identification Form'' (EPA
Form 8700-12) whenever there is a change in name, mailing address,
contact person, contact address, telephone number, ownership, type of
regulated waste activity, description of regulated wastes managed, or
if the generator permanently ceases the regulated waste activity. This
notification must be submitted to the DNREC Secretary no less than 10
days prior to the implementation of the change(s). The Federal
regulations at 40 CFR 262.12 do not require the submission of a ``RCRA
Subtitle C Site Identification Form'' (EPA Form 8700-12) whenever there
is a change in name, mailing address, contact person, contact address,
telephone number, ownership, type of regulated waste activity,
description of regulated wastes managed, or if the generator
permanently ceases the regulated waste activity. Therefore, this
provision of Delaware's regulations is more stringent than the Federal
requirement.
    (d) The Federal requirements in 40 CFR 262.20 detail the procedures
generators must follow when preparing a manifest. The paragraph at 40
CFR 262.20(e) includes conditions whereby generators that generate more
than 100 kilograms, but less than 1000 kilograms

in a calendar month would be exempt from the manifest requirements.
Delaware's regulations at DRGHW 262.20 also include guidelines for the
preparation of a manifest. However, paragraph 262.20(e) in the DRGHW is
labeled as ``Reserved''. Therefore, the manifest exemption for
generators that generate more than 100 kilograms, but less than 1000
kilograms of hazardous waste in a calendar month that is included in
the CFR is excluded from Delaware's regulations. Thus, Delaware
regulations are considered to be more stringent.
    (e) The Federal regulations promulgated at 40 CFR 262.44 state that
generators who generate more than 100 kilograms, but less than 1000
kilograms of hazardous waste in a calendar month are subject to
reporting and recordkeeping requirements in 40 CFR 262.40(a), (c), and
(d); 40 CFR 262.42(b); and 40 CFR 262.43. Delaware's regulations impose
additional reporting and recordkeeping requirements on these
generators. Specifically, Delaware's regulations at DRGHW 262.44 call
for generators who generate more than 100 kilograms, but less than 1000
kilograms to follow the reporting and recordkeeping requirements in
DRGHW 262.40(a), (b), (c), and (d); DRGHW 262.42(b); and DRGHW 262.43.
Therefore, Delaware's regulations are more stringent than the Federal
regulations.
    (f) The Delaware regulations at DRGHW 265.176(b) require the
owner(s) or operator(s) of waste treatment, storage, and disposal
facilities to take precautions to prevent accidental ignition or
reaction of ignitable or reactive waste. Specifically, owner(s) or
operator(s) must implement preventative measures including: Separating
and protecting ignitable or reactive waste from sources of ignition or
reaction, confining smoking and open flame to specially designated
locations while ignitable or reactive waste is being handled, and
conspicuously placing ``No smoking'' signs wherever there is a hazard
from ignitable or reactive waste. The Federal regulation promulgated at
40 CFR 265.176 does not include provisions for owner(s) or operator(s)
of waste treatment, storage, and disposal facilities to prevent
accidental ignition or reaction of ignitable or reactive waste. Hence,
Delaware's regulation is more stringent.
    (g) The Federal regulations at 40 CFR 268.7 include testing,
tracking, and recordkeeping requirements for generators, treaters, and
disposal facilities. The provision at 40 CFR 268.7(a)(1) states that a
generator must determine whether its hazardous waste must be treated
before it can be land disposed. It also says that generators can make
this determination by either testing the waste or using knowledge of
the waste. The provision also gives generators the option to send their
waste to a RCRA-permitted hazardous waste facility, where the facility
would have to test the hazardous waste. Delaware also has testing,
tracking, and recordkeeping requirements for generators, treaters, and
disposal facilities, which can be found at DRGHW 268.7. Delaware's
regulations at DRGHW 268.7(a)(1) require that generators determine
whether their hazardous waste must be treated before it can be land
disposed. Similar to the federal requirements, Delaware's regulations
state that generators can either test the waste or use knowledge of the
waste to make this determination. However, Delaware's regulations do
not include a provision to allow generators to send their waste to a
RCRA-permitted facility for testing. Therefore, Delaware's requirements
are more stringent than Federal requirements.
    (h) The Delaware regulations promulgated at DRGHW 279.10(i) state
that marketers and burners of used oil who market used oil containing
any quantifiable level of polychlorinated biphenyls (PCBs) are subject
to both the ``Standards for the Management of Used Oil'' set forth in
DRGHW Part 279 and the requirements found at 40 CFR 761.20(e). The
Federal regulations at 40 CFR 279.10(i), however, list the criteria
whereby used oil containing PCBs may become subject to both the
``Standards for the Management of Used Oil'' and the requirements of 40
CFR part 761. As a result, under the Federal regulations, marketers and
burners or used oil who market used oil containing PCBs may be subject
to either the requirements of 40 CFR part 279 or the requirements of 40
CFR part 761. Because Delaware always requires compliance with both
parts of the regulations, Delaware's regulations are more stringent.
    (i) The Delaware regulations at DRGHW 279.22(b)(3) state that
containers and aboveground tanks utilized to store used oil at
generator facilities must be closed during storage, except when it is
necessary to add or remove oil. The Federal regulations at 40 CFR
279.22(b) do not require that containers and aboveground storage tanks
remain closed during storage, thereby making Delaware's regulations
more stringent.

I. Who handles permits after the authorization takes effect?

    After this authorization revision, Delaware will continue to issue
permits covering all the provisions for which it is authorized and will
administer all such permits. EPA will continue to administer any RCRA
hazardous waste permits or portions of permits that it issued prior to
the effective date of this authorization until the timing and process
for effective transfer to the State are mutually agreed upon. Until
such time as EPA formally transfers responsibility for a permit to
Delaware and EPA terminates its permit, EPA and Delaware agree to
coordinate the administration of such permit in order to maintain
consistency. EPA will not issue any more new permits or new portions of
permits for the provisions listed in Section G after the effective date
of this authorization. EPA will continue to implement and issue permits
for HSWA requirements for which Delaware is not yet authorized.

J. How does this action affect Indian Country (18 U.S.C. 115) in
Delaware?

    Delaware is not seeking authority to operate the program on Indian
lands, since there are no Federally-recognized Indian Lands in
Delaware.

K. What is codification and is epa codifying Delaware's hazardous waste
program as authorized in this rule?

    Codification is the process of placing the State's statutes and
regulations that comprise the State's authorized hazardous waste
program into the Code of Federal Regulations. We do this action by
referencing the authorized State rules in 40 CFR part 272. EPA reserves
the amendment of 40 CFR part 272, subpart I, for this authorization of
Delaware's program revisions until a later date.

L. Administrative Requirements

    The Office of Management and Budget (OMB) has exempted this action
from the requirements of Executive Order 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 State
requirements pursuant to RCRA section 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 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). In any case, Executive Order
13175 does not apply to this rule since there are no Federally
recognized tribes in Delaware.
    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 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 concern environmental health or safety
risks that may disproportionately affect children. 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 section 3006(b), 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 EPA, when it
reviews a State authorization application, to require the use of any
particular voluntary consensus standard in place of another standard
that satisfies the requirements of RCRA. Thus, the requirements of the
National Technology Transfer and Advancement Act of 1995 (15 U.S.C.
3701, et seq.) do not apply. As required by section 3 of Executive
Order 12988 (61 FR 4729, February 7, 1996), in issuing this rule, EPA
has taken the necessary steps to eliminate drafting errors and
ambiguity, minimize potential litigation, and provide a clear legal
standard for affected conduct. EPA has complied with Executive Order
12630 (53 FR 8859, March 18, 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.). Burden is
defined at 5 CFR 1320.3(b). 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. 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 is effective October 10, 2017.
