Download as PDF Federal Register / Vol. 86, No. 75 / Wednesday, April 21, 2021 / Proposed Rules 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 TSD has more information on our evaluation. 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 21, 2021. 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 the MDAQMD rule 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). khammond on DSKJM1Z7X2PROD with PROPOSALS 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 VerDate Sep<11>2014 17:16 Apr 20, 2021 Jkt 253001 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); • 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).

TABLE 1—SUBMITTED RULE Local agency Rule No. SMAQMD .......... Rule title 414 Water Heaters, Boilers and Process Heaters Rated Less Than 1,000,000 Btu per Hour. On July 23, 2019, the submittal for SMAQMD Rule 414 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? We approved an earlier version of Rule 414 into the SIP on April 5, 2011 (76 FR 67366). The SMAQMD adopted revisions to the SIP-approved version on October 25, 2018, and CARB submitted them to us on January 23, 2019. khammond on DSKJM1Z7X2PROD with PROPOSALS C. What is the purpose of the submitted rule revision? Emissions of NOX contribute to the production of ground-level ozone, smog and paticulate matter, which harm human health and the environment. Section 110(a) of the CAA requires states to submit regulations that control NOX emissions. Rule 414 limits NOX emissions from water heaters, boilers and process heaters rated less than 1 million Btu/hr.1 The revised rule adds an exemption for hot water pressure washers (‘‘washers’’) in addition to several housekeeping changes. Washers unintentionally fell within the definition of water heaters subject to Rule 414 when it was originally adopted in 1996 but have never been regulated by the rule.2 Washers are portable, installation of emissions controls is difficult/impractical, and there are currently no commercially available certified washers within the District that 1 British thermal unit (Btu) per hour: The amount of heat required to raise the temperature of one pound of water from 59 °F to 60 °F at one atmosphere. 2 SMAQMD, Statement of Reasons, Rule 414, Water Heaters, Boilers and Process Heaters Rated Less Than 1,000,000 Btu per Hour, and Rule 419, NOX from Miscellaneous Combustion Units, Proposed Amendments September 24, 2018, p.5, 18. VerDate Sep<11>2014 17:16 Apr 20, 2021 Amended Jkt 253001 meet the rule’s NOX emissions limits.3 The District has never taken emissions reductions credit for this source because washers were never counted as part of the emissions inventory.4 Therefore, the emissions reductions forgone (theoretical emissions reductions if this source had been included from the outset) has no impact on the rule’s reduction commitment. Further, the emissions forgone are estimated to be only 0.1 to 0.3 percent of the 0.71 tons/ day reduction commitment for Rule 414. The small forgone emissions will have no practical impact on the District’s attainment plans for the 2008 or 2015 ozone national ambient air quality standards or reasonable further progress. 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 NOX in ozone nonattainment areas classified as Moderate or above (see CAA sections 182(b)(2) and 182(f)). The SMAQMD regulates an ozone nonattainment area classified as Severe-15 for the 2008 83 Email dated March 8, 2021, from Kevin J.

However, because this rule does not affect major sources, it does not need to implement section 182(b)(2) RACT. While section 182(b)(2) RACT does not apply, the Sacramento Federal Ozone Nonattainment Area is subject to the SIP requirement to provide for the implementation of all reasonably available control measures (RACM) and for attainment of the NAAQS.

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

    On July 23, 2019, the submittal for SMAQMD Rule 414 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?

    We approved an earlier version of Rule 414 into the SIP on April 5, 
2011 (76 FR 67366). The SMAQMD adopted revisions to the SIP-approved 
version on October 25, 2018, and CARB submitted them to us on January 
23, 2019.

C. What is the purpose of the submitted rule revision?

    Emissions of NOX contribute to the production of ground-
level ozone, smog and paticulate matter, which harm human health and 
the environment. Section 110(a) of the CAA requires states to submit 
regulations that control NOX emissions. Rule 414 limits 
NOX emissions from water heaters, boilers and process 
heaters rated less than 1 million Btu/hr.\1\ The revised rule adds an 
exemption for hot water pressure washers (``washers'') in addition to 
several housekeeping changes. Washers unintentionally fell within the 
definition of water heaters subject to Rule 414 when it was originally 
adopted in 1996 but have never been regulated by the rule.\2\ Washers 
are portable, installation of emissions controls is difficult/
impractical, and there are currently no commercially available 
certified washers within the District that meet the rule's 
NOX emissions limits.\3\ The District has never taken 
emissions reductions credit for this source because washers were never 
counted as part of the emissions inventory.\4\ Therefore, the emissions 
reductions forgone (theoretical emissions reductions if this source had 
been included from the outset) has no impact on the rule's reduction 
commitment. Further, the emissions forgone are estimated to be only 0.1 
to 0.3 percent of the 0.71 tons/day reduction commitment for Rule 414. 
The small forgone emissions will have no practical impact on the 
District's attainment plans for the 2008 or 2015 ozone national ambient 
air quality standards or reasonable further progress. 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 NOX in ozone 
nonattainment areas classified as Moderate or above (see CAA sections 
182(b)(2) and 182(f)). The SMAQMD regulates an ozone nonattainment area 
classified as Severe-15 for the 2008 8-hour ozone National Ambient Air 
Quality Standards (NAAQS) and Moderate for the 2015 NAAQS (40 CFR 
81.305). However, because this rule does not affect major sources, it 
does not need to implement section 182(b)(2) RACT. While section 
182(b)(2) RACT does not apply, the Sacramento Federal Ozone 
Nonattainment Area is subject to the SIP requirement to provide for the 
implementation of all reasonably available control measures (RACM) and 
for attainment of the NAAQS. Guidance and policy documents that we used 
to evaluate enforceability, revision/relaxation and rule stringency 
requirements for the applicable criteria pollutants include the

B. Does the rule meet the evaluation criteria?

    This rule meets CAA requirements and is consistent with relevant 
guidance regarding enforceability, RACM, and SIP revisions. The TSD has 
more information on our evaluation.

C. The EPA Recommendations To Further Improve the Rule

    The TSD includes recommendations for the next time the local agency 
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 May 21, 2021. 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 the SMAQMD rule 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 (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);
     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).
