ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 52
[EPA-R09-OAR-2021-0452; FRL-8834-01-R9]
Air Plan Approval; California; Opacity Testing of Heavy-Duty
Diesel Vehicles
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing to
approve a revision to the California State Implementation Plan (SIP)
concerning particulate matter (PM) emissions from heavy-duty (HD)
diesel vehicles. We are proposing to approve state rules to regulate
these emission sources under the Clean Air Act (CAA or the Act). We are
taking comments on this proposal and plan to follow with a final
action.
DATES: Comments must be received on or before December 6, 2021.
ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R09-
OAR-2021-0452 at https://www.regulations.gov. For comments submitted at
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

I. The State's Submittal
A. What rules did the State submit?
Table 1 lists the rules addressed by this proposal with the dates
that they were adopted by the California Air Resources Board (CARB) and
submitted to the EPA.
Table 1--Submitted Rules

Agency Rule No. Rule title Amended Submitted
----------------------------------------------------------------------------------------------------------------
CARB......................... Title 13, Division 3, Heavy-Duty Diesel Smoke 07/01/2019 02/13/2020

----------------------------------------------------------------------------------------------------------------
On August 13, 2020, the submittal from CARB was deemed by operation
of law to meet the completeness criteria in 40 CFR part 51 Appendix V,
which must be met before formal EPA review.
---------------------------------------------------------------------------
\1\ Chapter 3.5 contains sections 2180-2189.
\2\ Chapter 3.6 contains sections 2190-2194.
---------------------------------------------------------------------------
B. Are there other versions of these rules?
There are no previous versions of the submitted rules in the
California SIP.
C. What is the purpose of the submitted rules?
Emissions of PM, including PM equal to or less than 2.5 microns in
diameter (PM2.5) and PM equal to or less than 10 microns in
diameter (PM10), contribute to effects that are harmful to
human
[[Page 61101]]
health and the environment, including premature mortality, aggravation
of respiratory and cardiovascular disease, decreased lung function,
visibility impairment, and damage to vegetation and ecosystems. Section
110(a) of the CAA requires states to submit regulations that control PM
emissions. The EPA's technical support document (TSD) has more
information about these rules.
II. The EPA's Evaluation and Action
A. How is the EPA evaluating the rules?
Rules in the SIP must be enforceable (see CAA section 110(a)(2)),
must not interfere with applicable requirements concerning attainment
and reasonable further progress or other CAA requirements (see CAA
section 110(l)), and must not modify certain SIP control requirements
in nonattainment areas without ensuring equivalent or greater emissions
reductions (see CAA section 193).
Guidance and policy documents that we used to evaluate
enforceability, revisions, relaxation and rule stringency requirements
for the applicable criteria pollutants include the following:
1. ``Issues Relating to VOC Regulation Cutpoints, Deficiencies,
and Deviations,'' (a.k.a., Bluebook) EPA OAQPS, May 25, 1988.
2. ``Guidance Document for Correcting Common VOC & Other Rule
Deficiencies,'' (a.k.a., Little Bluebook), EPA Region 9, August 21,
2001.
3. ``Guidance to States on In-Use Smoke Test Procedure for
Highway Heavy-Duty Diesel Vehicles,'' EPA OAR, April 3, 1997.
4. ``Guidance to States on Smoke Opacity Cutpoints to be used
with the SAE J1667 In-Use Smoke Test Procedure,'' EPA OAR, February
25, 1999.
B. Do the rules meet the evaluation criteria?
These rules meet CAA requirements and are consistent with relevant
guidance regarding enforceability and SIP revisions. The standards set
forth in the rules listed above (referred to as the ``heavy-duty
vehicle inspection program'' (HDVIP) and the ``periodic smoke
inspection program'' (PSIP)) are more stringent than the opacity
standards set forth in the EPA's guidance to states.\3\ Further, while
EPA's 1999 guidance establishes recommendations for states to uniformly
establish opacity standards, states have authority under CAA section
209(d) to establish their own in-use standards for motor vehicles. The
TSD has more information on our evaluation.

---------------------------------------------------------------------------
C. The EPA's Recommendations To Further Improve the Rules
The TSD includes recommendations for the next time CARB modifies
the rules.
D. Public Comment and Proposed Action
As authorized in section 110(k)(3) of the Act, the EPA proposes to
fully approve the submitted rules because they fulfill all relevant
requirements. We will accept comments from the public on this proposal
until December 6, 2021. If we take final action to approve the
submitted rules, our final action will incorporate these rules into the
federally enforceable SIP.
III. Incorporation by Reference
In this rule, the EPA is proposing to include in a final EPA rule
regulatory text that includes incorporation by reference. In accordance
with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by
reference the California rules described in Table 1 of this preamble.
The EPA has made, and will continue to make, these materials available
through https://www.regulations.gov and at the EPA Region IX Office
(please contact the person identified in the FOR FURTHER INFORMATION
CONTACT section of this preamble for more information).
IV. Statutory and Executive Order Reviews
Under the Clean Air Act, the Administrator is required to approve a
SIP submission that complies with the provisions of the Act and
applicable federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a).
Thus, in reviewing SIP submissions, the EPA's role is to approve state
choices, provided that they meet the criteria of the Clean Air Act.
Accordingly, this proposed action merely proposes to approve state law
as meeting federal requirements and does not impose additional
requirements beyond those imposed by state law. For that reason, this
proposed action:
Is not a ``significant regulatory action'' subject to
review by the Office of Management and Budget under Executive Orders
12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21,
2011);
Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
Is certified as not having a significant economic impact
on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.);
Does not contain any unfunded mandate or significantly or
uniquely affect small governments, as described in the Unfunded
Mandates Reform Act of 1995 (Publ. L. 104-4);
Does not have federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
Is not an economically significant regulatory action based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
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; and
Does not provide the EPA with the discretionary authority
to address disproportionate human health or environmental effects with
practical, appropriate, and legally permissible methods under Executive
Order 12898 (59 FR 7629, February 16, 1994).
In addition, the SIP is not approved to apply on any Indian
reservation land or in any other area where the EPA or an Indian tribe
has demonstrated that a tribe has jurisdiction. In those areas of
Indian country, the rule does not have tribal implications and will not
impose substantial direct costs on tribal governments or preempt tribal
law as specified by Executive Order 13175 (65 FR 67249, November 9,
2000).
