MDAQMD............................. 1160 Internal Combustion Engines 01/23/23 03/03/23
----------------------------------------------------------------------------------------------------------------
Pursuant to CAA section 110(k)(1)(B) and 40 CFR part 51, appendix
V, the EPA determined that the submittal for MDAQMD Rule 1160 met the
completeness criteria on March 17, 2023.
B. Are there other versions of this rule?
On September 10, 2021 (86 FR 50643), we took final action on a
limited approval and limited disapproval of an earlier version of Rule
1160. This limited approval final action approved this earlier version
of Rule 1160 into the SIP, including those rule provisions identified
as deficient. In response to our limited disapproval final action, the
MDAQMD adopted revisions to the SIP-approved version on January 23,
2023 and CARB submitted them to us on March 3, 2023. In its submittal
letter, CARB requested that, upon approval of the revised version of
Rule 1160, the EPA remove the old version of this rule from the SIP. If
we take final action to approve the January 23, 2023 version of Rule
1160, this version will replace the previously approved version of this
rule in the SIP.
C. What is the purpose of the submitted rule revision?
Emissions of NOX and VOCs contribute to the production
of ground-level ozone, smog and particulate matter, which harm human
health and the environment. Section 110(a) of the CAA requires states
to submit regulations that control NOX and VOC emissions.
Sections 182(b)(2) and (f) require that SIPs for ozone nonattainment
areas classified as Moderate or above implement reasonably available
control technology (RACT) for any source covered by a Control
Techniques Guidelines (CTG) document and for any major source of VOCs
or NOX. Rule 1160 regulates NOX emissions from
major sources of NOX and has been submitted by CARB and the
air district to implement RACT for these sources. The revised version
of Rule 1160 was submitted to address the deficiencies identified in
our September 10, 2021 limited disapproval final action of the previous
version of Rule 1160, and to ensure that the air district implements
RACT level controls for all major stationary sources of NOX.
II. The EPA's Evaluation and Action
A. How is the EPA evaluating the rule?
Rules in the SIP must be enforceable (see CAA section 110(a)(2)),
and must not interfere with applicable
[[Page 20789]]
requirements concerning attainment and reasonable further progress or
other CAA requirements (see CAA section 110(l)).
Generally, SIP rules must require RACT for each category of sources
covered by a CTG document as well as each major source of
NOX and VOCs in ozone nonattainment areas classified as
moderate or above (see CAA sections 182(b)(2) and 182(f)). The MDAQMD
regulates an ozone nonattainment area classified as Severe-15 for the
1997 8-hour ozone National Ambient Air Quality Standard (NAAQS) and the
2008 8-hour ozone NAAQS (40 CFR 81.305). Therefore, MDAQMD must
implement RACT.
Guidance and policy documents that we used to evaluate
enforceability, revision/relaxation and rule stringency requirements
for the applicable criteria pollutants include the following:
1. ``Issues Relating to VOC Regulation Cutpoints, Deficiencies, and
Deviations,'' EPA, May 25, 1988 (the Bluebook, revised January 11,
1990).
2. ``Guidance Document for Correcting Common VOC & Other Rule
Deficiencies,'' EPA Region 9, August 21, 2001 (the Little Bluebook).
3. ``Control of Volatile Organic Emissions from Solvent Metal
Cleaning,'' EPA-450/2-77-022, November 1977.
4. ``NOX Emissions from Stationary Reciprocating
Internal Combustion Engines,'' EPA-453/R-93-032, July 1993.
5. ``Stationary Spark-Ignited Internal Combustion Engines,'' CARB,
November 2001.
B. Does the rule meet the evaluation criteria?
This rule meets CAA requirements and is consistent with relevant
guidance regarding enforceability, RACT, and SIP revisions. The revised
version of Rule 1160 removed the alternative compliance option that the
EPA identified as deficient in our September 10, 2021 final action. As
a result, covered engines in the District no longer have the option to
generate an alternative compliance plan in place of complying with the
limits in the rule. However, the rule does include a specialized
provision that governs five units that previously complied with the
rule via an alternative compliance plan. The rule requires five
specific internal combustion engines located at the Pacific Gas &
Electric Facility Hinkley Compressor Station in Hinkley, California to
operate, in aggregate, no greater than 2,600 engine hours per calendar
year. Once operations of these engines exceed this limit, the engines
will be subject to the NOX emission limits of the rule. This
represents less than 6% of the total capacity of these engines. Given
the costs associated with retrofitting these low-use engines, which the
facility needs to keep online for occasional peaking capacity, the EPA
concludes that additional controls for these units are not reasonably
available. The EPA's reasoning is explained in greater detail in the
technical support document (TSD) located in the docket of this
rulemaking.
The revised version of Rule 1160 also adds testing and compliance
requirements for regulated internal combustion engines without emission
control equipment. The lack of compliance requirements for such units
was identified as a deficiency in the EPA's prior limited disapproval
of Rule 1160. As described in greater detail in our TSD, the EPA
concludes that these added compliance requirements cure the previously
identified deficiency. The EPA's TSD has more information about this
rule.
C. Public Comment and Proposed Action
As authorized in section 110(k)(3) of the Act, the EPA proposes to
fully approve the submitted rule because it fulfills all relevant
requirements. We will accept comments from the public on this proposal
until May 8, 2023. If we take final action to approve the submitted
rule, our final action will incorporate this rule 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 MDAQMD Rule 1160, Internal Combustion Engines, amended on
January 23, 2023 which regulates NOX and VOC emissions from
internal combustion engines as discussed in section II 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 (Pub. 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); and
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.
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).
Executive Order 12898 (Federal Actions to Address Environmental
Justice in Minority Populations and Low-Income Populations, 59 FR 7629,
February 16, 1994) directs Federal agencies to identify and address
``disproportionately high and adverse human health or environmental
effects'' of their actions on minority populations and low-income
populations to the greatest extent practicable and
[[Page 20790]]
permitted by law. EPA defines environmental justice (EJ) as ``the fair
treatment and meaningful involvement of all people regardless of race,
color, national origin, or income with respect to the development,
implementation, and enforcement of environmental laws, regulations, and
policies.'' EPA further defines the term fair treatment to mean that
``no group of people should bear a disproportionate burden of
environmental harms and risks, including those resulting from the
negative environmental consequences of industrial, governmental, and
commercial operations or programs and policies.''
The State did not evaluate environmental justice considerations as
part of its SIP submittal; the CAA and applicable implementing
regulations neither prohibit nor require such an evaluation. EPA did
not perform an EJ analysis and did not consider EJ in this action.
Consideration of EJ is not required as part of this action, and there
is no information in the record inconsistent with the stated goal of
Executive Order 12898 of achieving environmental justice for people of
color, low-income populations, and Indigenous peoples.
