Table 1--Submitted Rule
----------------------------------------------------------------------------------------------------------------
Local agency Rule No. Rule title Adopted Submitted
----------------------------------------------------------------------------------------------------------------
SDCAPCD............................ 69.2.2 Medium Boilers, Process 09/09/21 03/09/22
Heaters, and Steam
Generators.
----------------------------------------------------------------------------------------------------------------
On September 9, 2022, the submittal for SDCAPCD Rule 69.2.2 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.
B. Are there other versions of this rule?
There are no previous versions of Rule 69.2.2 in the SIP. The
SDCAPCD adopted an earlier version of this rule on July 8, 2020, which
was submitted to the EPA on September 21, 2020 (``2020 submittal'').
The EPA provided comments for rule revisions to SDCAPCD without acting
on the 2020 submittal, and the SDCAPCD subsequently amended the rule.
Rule 69.2.2 was re-submitted to the EPA on March 9, 2022 (``2022
submittal''), but the background information for Rule 69.2.2 was not
included. In a letter to the EPA Region IX Regional Administrator dated
November 22, 2022, CARB withdrew the 2020 submittal. The EPA will use
the background information in the Staff Report from the 2020 submittal
to proceed with our action on the 2022 submittal, as SDCAPCD's
September 21, 2022 withdrawal request letter to CARB clarifies.
C. What is the purpose of the submitted rule?
Emissions of NO<INF>X</INF> contribute to the production of ground-
level ozone and smog, which harm human health and the environment.
Section 110(a) of the CAA requires states to submit regulations that
control NO<INF>X</INF> emissions. Rule 69.2.2 regulates boilers,
process heaters, and steam generators (units) with a heat input rating
greater than 2 million British thermal unit (Btu) per hour to less than
5 million Btu per hour that are manufactured, sold, offered for sale or
distributed, or installed for use within San Diego County. New units
that operate on gaseous fuel have a NO<INF>X</INF> emission limit of 30
parts per million by volume (ppmv) and new units that operate on liquid
fuel have a NO<INF>X</INF> emission limit of 40 ppmv. Units that
operate on a mixture of liquid and gaseous fuels must calculate their
heat-input weighted average to comply with the NO<INF>X</INF> emission
limits of the rule. The rule also gives a CO emission limit of 400 ppmv
for new units. All emission limits are calculated at 3 percent oxygen
(O<INF>2</INF>). Existing or relocated units, along with new units, are
required to have a tune-up once a year. New units are required to
monitor the burning of liquid and gaseous fuel through a non-
resettable, totalizing meter to measure either the mass flow rate or
volumetric flow rate, temperature, and pressure of each fuel to the
unit. Manufacturers of units without a permit to operate that are sold
in San Diego County must apply for certification. Facility operators or
owners of these units must apply for an authority to construct/permit
to operate or must register the unit to demonstrate that the unit
complies with the emission limits of Rule 69.2.2. Test methods are
provided in Rule 69.2.2 for new unit compliance testing and
certification for sale in San Diego County. Test methods are also
provided for new units certifying their higher heating value of a fuel
if not provided by a third party provider.
The EPA's technical support document (TSD) has more information
about this rule.
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)),
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).
Generally, SIP rules must require reasonably available control
technology (RACT) for each major source of NO<INF>X</INF> in ozone
nonattainment areas classified as Moderate or above (see CAA sections
182(b)(2) and 182(f)). The SDCAPCD regulates an ozone nonattainment
area classified as Severe for both the 2008 and 2015 8-hour National
Ambient Air Quality Standards NAAQS (40 CFR 81.305). Therefore, this
rule 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. EPA, ``Issues Relating to VOC Regulation Cutpoints, Deficiencies,
and Deviations,'' May 25, 1988 (the Bluebook, revised January 11,
1990).
2. EPA Region IX, ``Guidance Document for Correcting Common VOC &
Other Rule Deficiencies,'' August 21, 2001 (the Little Bluebook).
3. EPA Region V, ``NO<INF>X</INF> Emissions from Industrial/
Commercial/Institutional (ICI) Boilers,'' March 1994.
4. CARB, ``Determination of Reasonably Available Control Technology
and Best Available Retrofit Control Technology for Industrial,
Institutional, and Commercial Boilers, Steam Generators, and Process
Heaters,'' July 18, 1991.
B. Does the rule meet the evaluation criteria?
This rule meets CAA requirements and is consistent with relevant
guidance regarding enforceability and SIP revisions. The TSD has more
information on our evaluation.
C. EPA Recommendations To Further Improve the Rule
The TSD also includes recommendations for the next time the SDCAPCD
modifies the rule.
D. 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 March 1, 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 San Diego County Air Pollution Control District Rule 69.2.2,
adopted on September 9, 2021, which regulates operations and emissions
of certain boilers, process heaters, and steam generators, as discussed
in section I. of this preamble. The EPA has made, and will continue to
make, these materials available through <a href="https://www.regulations.gov">https://www.regulations.gov</a> 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:
<bullet> 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);
<bullet> Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
<bullet> 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.);
<bullet> 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);
<bullet> Does not have federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
<bullet> Is not an economically significant regulatory action based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
<bullet> Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001); and
<bullet> 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.
The state did not evaluate environmental justice considerations as
part of its SIP submittal. There is no information in the record
inconsistent with the stated goals of Executive Order 12898 (59 FR
7629, February 16, 1994) of achieving environmental justice for people
of color, low-income populations, and indigenous peoples.
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).
