40 CFR Part 52

[EPA-R09-OAR-2020-0605; FRL-10019-34-Region 9]

Air Plan Approval; California; Imperial County Air Pollution Control District

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:


[top] The Environmental Protection Agency (EPA) is proposing to approve a revision to the Imperial County Air Pollution Control District (ICAPCD) portion of the California State Implementation Plan (SIP). This revision concerns emissions of oxides of nitrogen (NO X ) from natural gas-fired page 10521 water heaters. We are proposing to approve a local rule 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 March 24, 2021.

I. The State's Submittal

A. What rule did the State submit?

Table 1 lists the rule addressed by this proposal with the dates that it was adopted by the local air agency and submitted by the California Air Resources Board (CARB).

Local agency Rule No. Rule title Adopted Submitted
ICAPCD 400.6 Natural Gas-Fired Water Heaters 11/26/2019 02/06/2020

On August 6, 2020, the submittal for ICAPCD Rule 400.6 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 400.6 in the SIP.

C. What is the purpose of the submitted rule?

Emissions of NO X contribute to the production of ground-level ozone, smog, and particulate matter (PM), which harm human health and the environment. Section 110(a) of the CAA requires states to submit regulations that control NO X emissions. Rule 400.6 is a new rule that limits NO X emissions in the ICAPCD from natural gas-fired water heaters rated less than 75,000 Btu/hr.1 The EPA's technical support document (TSD) has more information about this rule.

Footnotes:

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

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 X in ozone nonattainment areas classified as Moderate or above (see CAA sections 182(b)(2) and 182(f)). The ICAPCD regulates an ozone nonattainment area classified as Moderate for the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS) (40 CFR 81.305) (84 FR 58641). 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 Imperial County ozone nonattainment area is still subject to the SIP requirement to implement all reasonably available control measures (RACM) and 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 following:

1. "State Implementation Plans; General Preamble for the Implementation of Title I of the Clean Air Act Amendments of 1990," 57 FR 13498 (April 16, 1992); 57 FR 18070 (April 28, 1992).

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 March 24, 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 ICAPCD 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).
