 AGENCY: Environmental Protection Agency (EPA).
 ACTION: Final rule.
 SUMMARY: The U.S. Environmental Protection Agency (EPA) is finalizing amendments to the National Volatile Organic Compound Emission Standards for Aerosol Coatings. This action revises national emission standards for the aerosol coatings (aerosol spray paints) category under the Clean Air Act (CAA), which requires control of volatile organic compound (VOC) emissions from certain categories of consumer and commercial products for purposes of reducing VOC emissions contributing to ozone formation and ozone nonattainment. The regulation employs a relative reactivity-based approach to control aerosol coating products' contribution to ozone formation by encouraging the use of less reactive VOC ingredients in formulations. In this final rule, the EPA is updating coating category product-weighted reactivity (PWR) limits, adding new compounds and reactivity factors, updating existing reactivity factors, revising the rule's default reactivity factor, amending thresholds for VOC regulated by the rule, amending reporting requirements, updating test methods to reflect more recent versions, adding a new compliance date, and making clarifying edits.

                     The EPA promulgated “The National Volatile Organic Compound Emission Standards for Aerosol Coatings,” on March 24, 2008 (73 FR 15604) and codified the action at 40 CFR part 59, subpart E (§§ 59.500 through 59.516). The rule establishes nationwide VOC reactivity-based standards for the aerosol coatings source category under the statutory authority of section 183(e) of the CAA (42 U.S.C. 7401 
                    *et seq.*). Section 183(e) requires the EPA to control VOC emissions from certain categories of consumer and commercial products for purposes of reducing VOC emissions that contribute to ozone formation and nonattainment of the ozone national ambient air quality standards (NAAQS). The EPA has amended the original aerosol coatings rule several times to respond to petitions and to make rule clarifications. Many of the amendments were in accordance with a provision in 40 CFR 59.511(j) that allows regulated entities who elect not to use the default reactivity factors (RF) to calculate PWR to “. . . petition the Administrator to add a compound to table 2A, 2B, or 2C of this subpart. Petitions must include the chemical name, [Chemical Abstract Services] (CAS) number, a statement certifying the intent to use the compound in an aerosol coatings product, and adequate information for the Administrator to evaluate the reactivity of the compound and assign a RF . . .” Accordingly, the EPA has amended the aerosol coatings rule to add 131 compounds, corresponding RFs, and CAS numbers for each compound or class of compounds listed in 40 CFR part 59, table 2 (79 FR 29604). As for rule clarifications, the EPA has made revisions that clarify which VOC are to be quantified in compliance determinations (79 FR 29604); to inform regulated entities that VOC normally exempt by definition under 40 CFR 51.100(s)(1) and (s)(5) must be counted as VOC for the purposes determining compliance with the aerosol coatings rule (74 FR 29595); and, to ensure that both the certifying entity and the regulated entity have full knowledge of responsibilities assumed by the certifying entity (74 FR 29595). More recently, on September 17, 2021, in response to petitions from American Coatings Association (ACA), the EPA proposed amendments to the aerosol coatings rule that promote consistency and uniformity between the California Air Resources Board (CARB) aerosol coating product regulation and the national aerosol coatings emission limitations, where appropriate (86 FR 51851). This action finalizes the Agency's response to the ACA petitions and makes additional revisions based on public comments the EPA received on the proposed action. For more information, see the docket for this action, Docket ID No. EPA-HQ-OAR-2006-0971, and section IV. of this preamble. *Organization of this document.*

Judicial Review and Administrative Reconsideration Under CAA section 307(b)(1), judicial review of this final action is available only by filing a petition for review in the United States Court of Appeals for the District of Columbia Circuit by March 18, 2025. Under CAA section 307(b)(2), the requirements established by this final rule may not be challenged separately in any civil or criminal proceedings brought by the EPA to enforce the requirements. Section 307(d)(7)(B) of the CAA further provides that only an objection to a rule or procedure which was raised with reasonable specificity during the period for public comment (including any public hearing) may be raised during judicial review. This section also provides a mechanism for the EPA to reconsider the rule if the person raising an objection can demonstrate to the Administrator that it was impracticable to raise such objection within the period for public comment or if the grounds for such objection arose after the period for public comment (but within the time specified for judicial review) and if such objection is of central relevance to the outcome of the rule. Any person seeking to make such a demonstration should submit a Petition for Reconsideration to the Office of the Administrator, U.S. EPA, Room 3000, WJC South Building, 1200 Pennsylvania Ave. NW, Washington, DC 20460, with a copy to both the person(s) listed in the preceding 
                    **FOR FURTHER INFORMATION CONTACT**

II. Background A. What amendments have been made since promulgation of the original rule? The EPA has amended the original aerosol coatings rule several times to respond to petitions and to make rule clarifications. Many of the amendments were in accordance with a provision in 40 CFR 59.511(j) that allows regulated entities who elect not to use the default RF to calculate PWR to “. . . petition the Administrator to add a compound to table 2A, 2B, or 2C of this subpart. Petitions must include the chemical name, [Chemical Abstract Services] (CAS) number, a statement certifying the intent to use the compound in an aerosol coatings product, and adequate information for the Administrator to evaluate the reactivity of the compound and assign a RF . . .” As such, the EPA has amended the rule to add 131 compounds, corresponding reactivity factors, and CAS numbers for each compound or class of compounds listed in 40 CFR part 59 table 2 (79 FR 29604). As for rule clarifications, the EPA has made revisions to clarify which volatile organic compounds must be quantified in compliance determinations (79 FR 29604); to inform regulated entities that VOC normally exempt by definition under 40 CFR 51.100(s)(1) and (s)(5) are to be counted as VOC for the purposes determining compliance with this rule (74 FR 29595); and to ensure that both the certifying entity and the regulated entity have full knowledge of responsibilities assumed by the certifying entity (74 FR 29595). B. What changes did we propose for the National Volatile Organic Compound Emission Standards for Aerosol Coatings source category on September 21, 2021? On September 17, 2021, in response to petitions from ACA, the EPA proposed amendments to the standards that promote consistency and uniformity between the CARB aerosol coating product regulation and the EPA aerosol coatings rule emission limitations, where appropriate (86 FR 51851). This action finalizes the Agency's response to the ACA petitions and makes additional revisions based on public comments received on the proposal. For more information, see the docket for this action, Docket ID No. EPA-HQ-OAR-2006-0971, and section IV. of this preamble. III. Summary of the Final Standards and Changes Since Proposal A. Table 1 to Subpart E of Part 59: Product-Weighted Reactivity Limits by Coatings Category This final rule updates the PWR limits for the coating categories listed in table 1 of 40 CFR part 59, subpart E. The changes, which are based on updates to the relative reactivity scale that underlies both the reactivity factors and limits, will further decrease the contribution of aerosol coatings to ozone formation. In addition, the EPA is adopting identical category names and limits as those in CARB's aerosol coating product regulation and, where possible, including them in the EPA's national aerosol coatings rule in table 1 of 40 CFR part 59, subpart E. This amendment also led to the Agency combining two sets of coatings subcategories into two main categories and adding corresponding limits for those categories, as follows: The subcategories “enamel,” “lacquer,” and “clear or metallic” coatings are now subsumed under the category heading, “Hobby/Model/Craft Coatings,” with a category limit of 1.6 grams of ozone per gram of VOC (g O3
                    /g VOC); and
                The subcategories “clear” and “pigmented” coatings are now subsumed under the category heading, “Shellac Sealers,” with a category limit of1.00 g O3
                    /g VOC. The EPA also is adding six new specialty coating categories and imposing corresponding emission limitations for consistency with CARB's aerosol coating product regulation, as follows: “Electrical/Electronic/Conformal Coatings,” with a category limit of 2.00 O3
                    /g VOC;
                “Flexible Coatings,” with a category limit of 1.60 O3
                    /g VOC;
                “Mold Release Coatings,” with a category limit of 1.10 O3
                    /g VOC;
                “Rust Converter,” with a category limit of 1.10 O3
                    /g VOC;
                “Two Component Coating,” with a category of 1.20 O3
                    /g VOC; and
                “Uniform Finish Coating,” with a category limit of 1.30 O3
                    /g VOC. B. Table 2A, 2B, and 2C to Subpart E of Part 59: Reactivity Factors, Aliphatic Hydrocarbon Solvent Mixtures, and Aromatic Hydrocarbon Solvent Mixtures The EPA is finalizing amendments to 40 CFR part 59 subpart E, tables 2A, 2B, and 2C by adding 17 new compounds and corresponding RF to table 2A, and by updating the RF of one existing compound mixture to table 2B. Of the 17 new compound additions to table 2A, 15 have an assigned maximum incremental reactivity (MIR) value in CARB's aerosol coatings regulation, which the Agency is adopting as RF values in this final action. The EPA is also finalizing the addition of two remaining compounds to table 2A: trans-1-chloro-3,3,3-trifluoropropene (HFO-1233zdE), CAS 102687-65-0, and diethyl carbonate, CAS 105-58-8, with RFs of 0.04 g O3
                    /g VOC and 0.71 g O3
                    /g VOC, respectively. The RFs that the EPA has assigned to these two compounds are based on MIR values 
                    ( print page 5700)
                    derived by Venecek [1]
                    
                     and Carter,[2]
                    
                     respectively. One of the compounds the EPA is adding, dipropylene glycol monomethyl ether, CAS 34590-94-8, is a mixture of isomers. Another compound, 2-[2-methoxypropoxy]-1-propanol, CAS 13588-28-8, is an isomer of dipropylene glycol monomethyl ether, which is already on table 2A; and the EPA is assigning both of those compounds an RF of 2.58 g O3
                    /g VOC. In addition to adding the new compounds listed above, the EPA is updating reactivity factors in tables 2A, 2B, and 2C for other compounds already addressed in the EPA's aerosol coatings rule to align with the MIR values in the current CARB aerosol coating product regulation.[3]
                    
                     This will maintain the internal consistency of the relative reactivity scale and changes to the limits finalized in 40 CFR part 59 subpart E, table 1. The updates to the existing RFs listed in tables 2A, 2B, and 2C will take effect on January 17, 2025. Regulated entities who are already formulating their products to meet CARB's aerosol coating product regulation may elect to use the new RFs and meet the new category emission limitations of the EPA's aerosol coatings rule upon the effective date of this action. However, regulated entities must use the new RFs and meet the new emission limitations by the compliance date. All regulated entities must come into compliance with all provisions in this final rule by July 17, 2025. C. The Default Reactivity Factor In the EPA's original national aerosol coatings rule, if a regulated entity used a VOC in an aerosol coating formulation that was not listed in tables 2A, 2B, or 2C, it was assigned a default RF of 22.04 g O3
                    /g VOC (see 40 CFR 59.505(e)(4) and 59.511(j)). In this final action, we reset the default RF for VOCs of unknown reactivity consistent with the methodology used in the original aerosol coatings rule, whereby we identified the VOC with the maximum RF value in table 2A, and then assigned that value as the default RF for any VOC that is not listed with a specific RF (73 FR 15610). Therefore, the EPA is resetting the default RF to 18.50 g O3
                    /g VOC, the highest value in table 2A of this final action. Furthermore, the EPA is finalizing two additional requirements related to the default RF. First, regulated entities shall include the name and CAS number of all VOCs for which they are using the default RF, as specified in the reporting requirements in 40 CFR 59.511. Second, if a regulated entity uses a VOC in a product that is not listed in table 2A, but its isomer is listed in table 2A, then the regulated entity shall use the RF of the isomer. If more than one isomer of that VOC, or mixtures of the isomers of that VOC, is listed in table 2A, then the regulated entity shall use the highest RF associated with the listed isomers or isomer mixtures. D. VOC Regulated by the Rule The EPA is not making changes to the current definition of VOC in 40 CFR 51.100(s)(7) in this final action. However, it is important to note that in the original aerosol coatings rule, the EPA amended the regulatory definition of VOC to remove the exemption of specific organic compounds identified in 40 CFR 51.100(s)(1) and (s)(5) for purposes of determining compliance with the reactivity-based emission limitations in the aerosol coatings rule. Thus, 40 CFR 51.100(s)(7) provides that “any organic compound in the volatile portion of an aerosol coating is counted towards the product's reactivity-based limit, as provided in part 59, subpart E. Therefore, the compounds that are used in aerosol coating products and that are identified in paragraph (s) of this section as negligibly reactive and excluded from the EPA's definition of VOC are to be counted towards a product's reactivity limit for the purposes of determining compliance with the EPA's aerosol coatings reactivity-based national regulation, as provided in part 59, subpart E.” To eliminate consideration of VOC that make 
                    *de minimis*
                     contributions to a product's overall reactivity in the original aerosol coatings rule, the EPA also excluded from the applicable emission limitations those compounds that: (a) contribute less than 0.1 percent of the product weight (regardless of their RF); and (b) have reactivities less than ethane and comprise less than 7.3 percent of product weight. We explained the basis for the derivation of the 7.3 percent threshold and its relationship to the RF for ethane and the default RF in the original rulemaking (see 73 FR 15604). In this action, the EPA is finalizing amendments to the aerosol coatings rule to retain part (a), where compounds that comprise less than 0.1 percent of the product weight are excluded from the product's mass-weighted reactivity, but eliminate part (b), the exclusion of low reactivity compounds that comprise more than 0.3 percent but less than 7.3 percent of the product weight. E. Electronic Reporting of Notifications and Reports The EPA is also finalizing the revision to the aerosol coatings rule to require that regulated entities submit electronic copies of required notifications and reports in template format through the EPA's Central Data Exchange (CDX) using the Compliance and Emissions Data Reporting Interface (CEDRI), instead of the current hard copy submission requirement. A description of the electronic data submission process is provided in the memorandum 
                    *Electronic Reporting Requirements for New Source Performance Standards (NSPS) and National Emission Standards for Hazardous Air Pollutants (NESHAP) Rules,*
                     available in the docket for this action. For the nine notifications and reports in the aerosol coatings rule, (
                    *i.e.,*
                     Temporary Variances, Initial Notification, Change to Information in Initial Notification, Response to Written Notification, Exemption Claim Initial Notification, Exemption Claim Annual Report, Notice of Certifying Entity to Maintain Records, Notice Rescinding Certification and Triennial Report), this final rule requires that regulated entities use the appropriate spreadsheet template to submit information to CEDRI. A final version of the spreadsheet template for these notifications and reports is included in the docket and on the CEDRI web page.[4]
                    
                     The EPA has also updated the spreadsheet in response to the comments received on the proposal. Furthermore, the EPA is finalizing revisions to the aerosol coatings rule that provide owners and operators the ability to seek extensions for submitting electronic reports for circumstances beyond the control of the facility, 
                    *i.e.,*
                     for a possible outage in the CDX or CEDRI or for a force majeure event, in the time just prior to a report's due date, as well as the process to assert such a claim. F. Test Methods Regulated entities may use formulation data to demonstrate compliance with the emission limitations in the aerosol coatings rule. However, it is also necessary to have test methods in place that can be used 
                    ( print page 5701)
                    by regulated entities, the EPA, or others to verify the accuracy of formulation data and determine compliance with the reactivity limits. In this final action, we are not requiring new test methods; instead, the EPA is amending the aerosol coatings rule to require use of the updated version of CARB Method 310, “Determination of Volatile Organic Compounds (VOC) in Consumer Products and Reactive Organic Compounds in Aerosol Coating Products,” May 25, 2018, when verifying compliance using test methods. For measurement of specular gloss, the EPA will continue to require regulated entities to use, “Standard Test Method for Specular Gloss,” ASTM Method D523-08 (2008), formerly ASTM D523-89 (1999). As noted in section IV.A. of this preamble, regulated entities may elect to use the updated RFs and meet the revised emission limitations in this final rule in advance of the compliance date, but if they do so they must use the updated test methods. IV. Response to Significant Comments The EPA received a total of eight letters commenting on the September 17, 2021, proposed rule.

                     by searching Docket ID No. EPA-HQ-OAR-2006-0971. A. Compliance Date of the Rule Four commenters requested that the EPA establish a 2-year compliance date for the revisions being made to the aerosol coatings rule in this final action. The commenters argue that sufficient time will be needed for manufacturers to comply with the new VOC MIR emission limitations if they do not already manufacture aerosol coating products for sale in California. In addition, one of the commenters asserts that a two-year compliance date will ensure that industry has sufficient time to reformulate their products and adapt their distribution methods to implement the amended rule's requirements effectively and efficiently. According to the commenter, when a rule is amended, industry requires a reasonable amount of lead time to adjust formulations and supply chain processes to ensure compliance with VOC limits, labeling, and reporting requirements. Additionally, commenters state that manufacturers will need sufficient time to properly communicate these changes to their distributors and retail customers to ensure compliance with amended VOC emission limitations. Therefore, the commenters assert, a compliance date of two years after publication of a final rule would give industry enough time to reformulate with the updated/added compounds and ensure compliance with the new coatings category limits. The EPA agrees that, especially for regulated entities that do not manufacture or sell products in California, additional time may be needed to come into compliance with the amendments to the aerosol coatings rule. However, the EPA has determined that the two-year compliance period requested by commenters is not warranted, because based upon information available to the agency most, if not all, manufacturers of aerosol coatings already manufacture products that meet the CARB emission limitations, either for themselves or for others. Commenters did not identify any specific manufacturers of aerosol coatings who do not do so. Nevertheless, in this final action, the EPA is providing additional time for manufactures to make any necessary adjustments by finalizing a six-month compliance date for the revised aerosol coatings rule requirements. It is important to note that the effective date of this rule is the date of publication in the 
                    **Federal Register**
                    , or January 17, 2025. In the intervening six months, all regulated entities are subject to the aerosol coatings rule in its current form but may elect to start complying with the amended aerosol coatings rule. This means that regulated entities, including those that are currently in compliance with the CARB aerosol coating product regulation on the effective date of this rule, may elect to begin complying immediately. However, all regulated entities shall come into compliance with all the provisions in this final action by July 17, 2025. The original tables with values for the PWR emission limits by coatings category and the reactivity factors are in appendix A—table 1 and tables 2A, 2B and 2C of this final action. B. Effective Date of the Final Rule Several commenters recommend that the EPA allow industry to use the new and updated RF values immediately, once they are finalized and published in the 
                    **Federal Register**
                    . The commenters assert that this would allow industry to use the new and updated reactivity values in their formulations to come into compliance with the new coatings category limits in table 1 sooner. The EPA agrees that this is appropriate. We note that the effective date of this rule indicates when regulated entities may elect to begin meeting the new aerosol coatings product-weighted coating category emission limitations in 40 CFR part 59, subpart E—table 1 using the corresponding reactivity factors in 40 CFR part 59, subpart E—table 2. The Agency directs the commenters to 40 CFR 59.502 and the 
                    **DATES**
                     section of this preamble, where the effective date of the rule is the date of publication in the 
                    **Federal Register**
                    , or January 17, 2025. Therefore, regulated entities may begin meeting the new emission limitations and using corresponding reactivity factors immediately upon publication of this final rule. The EPA emphasizes that all regulated entities must do so by the compliance date. Also note that, although regulated entities may elect to begin to use the new RF values immediately on January 17, 2025, the EPA is granting a six-month compliance date. In summary, the EPA has added a provision to 40 CFR 59.502 to clarify that regulated entities may elect to begin meeting the new coating category product-weighted limits in 40 CFR part 59, subpart E—table 1 and use the corresponding reactivity factors in 40 CFR part 59, subpart E—table 2 upon the effective date of the rule, or January 17, 2025. However, all regulated entities must come into compliance with all the revised provisions in the amended aerosol coatings rule by July 17, 2025. For the reasons discussed above, this final rule is effective immediately upon publication. Section 553(d)(3) of the Administrative Procedure Act (“APA”), 5 U.S.C. 553(d), provides that final rules shall not become effective until 30 days after publication in the 
                    **Federal Register**
                     “except . . . as otherwise provided by the agency for good cause.” The purpose of this provision is to “give affected parties a reasonable time to adjust their behavior before the final rule takes effect.” 
                    *Omnipoint Corp.*
                     v. 
                    *Fed. Commc'n Comm'n,*
                     78 F.3d 620, 630 (D.C. Cir. 1996). Thus, in determining whether good cause exists to waive the 30-day delay, an agency should “balance the necessity for immediate implementation against principles of fundamental fairness which require that all affected persons be afforded a reasonable amount of time to prepare for 
                    ( print page 5702)
                    the effective date of its ruling.” Gavrilovic, 551 F.2d at 1105. The EPA has determined that there is good cause for making this final rule effective immediately because, as noted above, regulated entities do not need to come into compliance with the revised provisions for another 181 days—that is, by July 17, 2025. C. Definitions Several commenters requested changes, additions, or deletions to the list of definitions included in the aerosol coatings rule. When CARB amended its aerosol coating product regulation in 2013, one commenter stated that they worked diligently with CARB staff to update the definitions so that they correctly characterized industry's products. The commenter noted that further alignment with the definitions in CARB's aerosol coatings regulation is critical and will assist with industry compliance. The EPA evaluated the commenters' suggestions and has revised some definitions in the updated aerosol coatings rule. Where appropriate, we have amended definitions in the EPA aerosol coatings rule to be consistent with the CARB's definitions. For example, for consistency, we have eliminated the use of the word “paint” in both category names and in definitions and replaced it with the more correct term “coating.” We have removed words from definitions that needlessly limited a definition, as suggested by commenters. The EPA has removed the term “synthetic” from the definition of slip-resistant coatings because it is possible that such a product could use non-synthetic material. We have also removed the term “elemental” from the definition of metallic coating, as recommended by a commenter. In several cases, we are unable to make the changes suggested by the commenters. The EPA does not agree that a claim made by a regulated entity on a label, or on a “principal display panel” as specified in CARB's rule, is sufficient to define a category. Our definitions are based solely on the function of the coating and not on the printed claims. Therefore, we will not add a sentence to coatings that defer to a “principal display panel,” nor will we include a definition of that term in this final rule. In addition, we will not include definitions of several terms recommended by the commenter but are not used in the EPA's aerosol coatings rule. For example, the term “Reactivity Limit” is the term used by CARB in its aerosol coating product regulation, while “Product-Weighted Reactivity (PWR) limit” is the term that the EPA uses in the national aerosol coatings rule. The EPA is not adding a definition for the term “Reactivity Limit” to the list of definitions because the Agency does not use this term in the aerosol coatings rule. A more complete discussion of the individual changes to definitions is included in the “Summary of Public Comments and Responses for the National Volatile Organic Compound Emissions for Aerosol Coatings—Amendments,” Docket ID No. EPA-HQ-OAR-2006-0971. D. VOC Regulated by the Rule The EPA proposed to retain a provision that excludes from the applicable limits those compounds that contribute less than 0.1 percent of the product weight (regardless of their RF) and eliminate a provision from 40 CFR 59.505 that excludes low reactivity compounds that comprise more than 0.1 percent but less than 7.3 percent of the product weight. The EPA received several comments supporting this revision and one that opposed it, based upon concerns that the exclusion of compounds could have unintended adverse impacts. The EPA has concluded that it is appropriate to make the proposed revisions and thus, we are amending 40 CFR 59.505 of this final rule, accordingly. We respond to the adverse comment in more detail in response to comment document titled, “Summary of Public Comments and Responses for the National Volatile Organic Compound Emissions for Aerosol Coatings—Amendments,” Docket ID No. EPA-HQ-OAR-2006-0971. E. Default Reactivity Factor Five commenters suggested that the EPA adopt a default RF of 11.97 g O3
                    /g VOC to align with CARB's default MIR value. The EPA considered whether to adopt CARB's default MIR value as the EPA's default RF in the amended national aerosol coatings rule but is declining to do so. The EPA's methodology for setting a default RF value in the original aerosol coatings rule was to require regulated entities to use the maximum RF value for the compounds specified in table 2. The EPA has used this conservative methodology for setting the default RF to help to ensure the protection of public health by reducing ozone that may result from new and/or previously unstudied VOCs. Consistent with this preferred methodology and considering the updates to RF values in table 2, the EPA is resetting the default RF to 18.50 g O3
                    /g VOC in this final action. V. Summary of Impacts A. Environmental Impacts There are no anticipated environmental impacts from compliance with this final rule. The revisions to the aerosol coatings rule in this final action are minor and not expected to result in net changes to an aerosol coating product's potential to form ozone because the overall average changes to the values used to measure reactivity of a given regulated product, 
                    *i.e.,*
                     category emission limitations and RFs, are small compared to the values in the original rule. The final action is, however, expected to improve upon the original aerosol coatings rule by making updates (
                    *e.g.,*
                     adding new compounds, updating reactivity factors, and adding electronic reporting) that promote consistency and uniformity between State and national regulations. The EPA anticipates that this final action will maintain the level of environmental protection to populations in affected ozone nonattainment areas without having any disproportionately high and adverse human health or environmental effects on any populations, including communities with environmental justice (EJ) concerns. B. Energy Impacts There are no adverse energy impacts anticipated from compliance with this final rule. C. Cost and Economic Impacts There are no adverse economic impacts anticipated from compliance with this final rule. This action primarily updates reactivity tables and factors and adds electronic reporting provisions. VI. Statutory and Executive Order Reviews Additional information about these statutes and Executive Orders can be found at 
                    *www.epa.gov/​laws-regulations/​laws-and-executive-orders.* A. Executive Order 12866: Regulatory Planning and Review and Executive Order 14094: Modernizing Regulatory Review This action is not a significant regulatory action as defined in Executive Order 12866, as amended by Executive Order 14094, and was therefore not subject to a requirement for Executive Order 12866 review. B. Paperwork Reduction Act (PRA) The information collection requirements in this final rule have been 
                    ( print page 5703)
                    submitted for approval to OMB under the PRA. The information collection request (ICR) document that the EPA prepared for this action has been assigned OMB control number 2060-0617, EPA ICR Number 2289.06. You can find a copy of the ICR in the docket for this rule, and it is briefly summarized here. The information collection requirements are not enforceable until OMB approves them. There is no increase in burden associated with this action because the rule primarily adds compounds and reactivity factors, updates category limits and reactivity factors, and adds electronic reporting provisions. The burden associated with the change from paper to electronic reporting in this final action will not increase significantly because of this action, and results in a slight decrease in the annual average burden for reporters. In the short term, regulated entities will need time to become familiar with the new reporting scheme and template. In the long term, however, the Agency anticipates that electronic reporting will reduce the burden as regulated entities become more familiar with the electronic reporting process. Additionally, there is a decrease in burden due to a decrease in respondents, which is due to updated information on the number of sources. *Respondents/affected entities:*
                     Manufacturers, distributors, and importers of aerosol coatings. *Respondent's obligation to respond:*
                     Mandatory (40 CFR part 59, subpart E). *Estimated number of respondents:*
                     47. *Frequency of response:*
                     Initially, triennially, and occasionally. *Total estimated burden:*
                     9,562 hours (per year). Burden is defined at 5 CFR 1320.3(b). *Total estimated cost:*
                     $740,520 (per year), includes no annualized capital or operation and maintenance costs. An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number. The OMB control numbers for the EPA's regulations in 40 CFR are listed in 40 CFR part 9. When OMB approves this ICR, the Agency will announce that approval in the 
                    **Federal Register**
                     and publish a technical amendment to 40 CFR part 9 to display the OMB control number for the approved information collection activities contained in this final rule. C. Regulatory Flexibility Act (RFA) I certify that this action will not have a significant economic impact on a substantial number of small entities under the RFA. In making this determination, the EPA concludes that the impact of concern for this rule is any significant adverse economic impact on small entities and that the Agency is certifying that this rule will not have a significant economic impact on a substantial number of small entities because the rule has no net increase in burden on the small entities subject to the rule. The EPA has determined that small entities will incur a reduction in burden over the long term because the primary revisions to the aerosol coatings rule include updating coating categories in table 1, adding compounds to table 2, and adding an electronic reporting provision, where the method of reporting from paper to electronic is the only change. The burden associated with the change from paper to electronic reporting will not increase significantly because of this action, at least in the long term. Small entities will need time to become familiar with the new reporting scheme and template. However, in the long term, the Agency anticipates that, because electronic reporting is more efficient than paper reporting, the burden will be reduced as small entities become more familiar with the electronic reporting process. We have therefore concluded that this action will have no net regulatory burden for all directly regulated small entities. D. Unfunded Mandates Reform Act (UMRA) This final action does not contain an unfunded mandate of $100 million (adjusted annually for inflation) or more (in 1995 dollars) as described in UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect small governments. The costs involved in this action are estimated not to exceed $183 million in 2023 dollars ($100 million in 1995 dollars adjusted for inflation using the GDP implicit price deflator) or more in any one year. E. Executive Order 13132: Federalism This action does not have federalism implications. It will not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. F. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments This action does not have Tribal implications as specified in Executive Order 13175. The final regulatory action does not have a substantial direct effect on one or more Indian Tribes, in that this action imposes no regulatory burdens on Tribes. Thus, Executive Order 13175 does not apply to this action. G. Executive Order 13045: Protection of Children From Environmental Health Risks and Safety Risks The EPA interprets Executive Order 13045 as applying only to those regulatory actions that concern environmental health or safety risks that the EPA has reason to believe may disproportionately affect children, per the definition of “covered regulatory action” in section 2-202 of the Executive Order. Therefore, this final action is not subject to Executive Order 13045 because it does not concern an increase in an adverse or environmental health risk or safety risk. Since this action does not concern human health, the EPA's Policy on Children's Health does not apply. H. Executive Order 13211 Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use This action is not subject to Executive Order 13211 because it is not a significant regulatory action under Executive Order 12866. I. National Technology Transfer and Advancement Act (NTTAA) and 1 CFR Part 51 The national VOC emission standards for aerosol coatings involves technical standards; however, no new technical standards are being finalized in this action. Instead, the EPA is amending this final rule to require that regulated entities use an updated version of an existing test method. As such, we conducted searches for the national VOC standards for aerosol coatings through the Enhanced NSSN Database managed by the American National Standards Institute. We also contacted VCS organizations and accessed and searched their databases. Searches were conducted for EPA Method 311 of 40 CFR part 63, appendix A. During the search, if the title or abstract (if provided) of the VCS described technical sampling and analytical procedures that are like the EPA's reference method, the EPA considered it as a potential equivalent method. All potential standards were reviewed to determine the practicality of the VCS for this final rule. This review requires significant method validation data which meets the requirements of EPA Method 301 for accepting alternative methods or scientific, engineering and policy equivalence to procedures in EPA reference methods. The EPA may 
                    ( print page 5704)
                    reconsider determinations of impracticality when additional information is available for particular VCS. One voluntary consensus standard was identified as an acceptable alternative to the EPA test method for the purposes of this rule. The voluntary consensus standard, CARB Method 310, “Determination of Volatile Organic Compounds in Consumer Products and Reactive Organic Compounds in Aerosol Coating Products” amended May 25, 2018 is an acceptable alternative to EPA Method 311 for determining speciated ingredients and weight percentage of each ingredient of each aerosol coating product. This method is used to determine the weight percent of VOC in consumer products and reactive organic compounds in aerosol coating products and is available from the California Air Resources Board (CARB), 1001 I Street, Sacramento, CA 95814. See 
                    *ww2.arb.ca.gov.*
                     In addition, the EPA is incorporating by reference the ASTM D523-08, Standard Test Method for Specular Gloss. This test method is used to measure light reflectiveness of paints, coatings and smooth surface materials and is referenced in CARB Method 310. It covers the measurement of the specular gloss of nonmetallic specimens for glossmeter geometries of 60, 20 and 85 degrees and is available at ASTM, International, 1850 M Street NW, Suite 1030, Washington, DC 20036. See 
                    *www.astm.org.* J. Executive Order 12898: Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Populations and Executive Order 14096: Revitalizing Our Nation's Commitment to Environmental Justice for All The EPA believes that the human health and environmental conditions that existed prior to this action do not result in disproportionate and adverse effects on communities with environmental justice concerns. As stated in section V.A. of the preamble of this action, there are no anticipated adverse environmental impacts and no adverse economic impacts anticipated from compliance with this final rule. The EPA believes that this action is not likely to result in new disproportionate and adverse effects on communities with environmental justice concerns. As stated in section I. of this action, section 183(e) of the CAA requires the control of VOC emissions from certain categories of consumer and commercial products for purposes of reducing VOC emissions contributing to ozone formation and nonattainment of the ozone NAAQS. The health and environmental risks associated with ozone were considered in the establishment of the ozone NAAQS. The level is designed to be protective of the public with an adequate margin of safety. Accordingly, these actions would help increase the level of environmental protection to populations in affected ozone nonattainment areas without having any disproportionately high and adverse human health or environmental effects on any populations, including communities with environmental justice concerns. K. Congressional Review Act (CRA) This action is subject to the CRA, and the EPA will submit a rule report to each House of the Congress and to the Comptroller General of the United States. This action is not a “major rule” as defined by 5 U.S.C. 804(2). List of Subjects in 40 CFR Part 59 Environmental protection

 4.Amend § 59.505 by revising paragraphs (c) through (e) and adding paragraph (h) to read as follows: § 59.505
  
 (c) You may use either formulation data (including information for both the liquid and propellant phases), CARB Method 310 (2018) (incorporated by reference, see § 59.515), or EPA's Method 311 (40 CFR part 63, appendix A), to calculate the PWR. However, if there are inconsistencies between the formulation data and the CARB Method 310 (2018) or EPA Method 311 results, the CARB Method 310 (2018) or EPA Method 311 results will govern. (d) If you manufacture a coating containing either an aromatic or aliphatic hydrocarbon solvent mixture, you must use the appropriate RF for that mixture provided in table 2B or 2C to this subpart when calculating the PWR using formulation data. However, when calculating the PWR for a coating containing these mixtures using data from CARB Method 310 (2018) (incorporated by reference, see § 59.515), or EPA Method 311—(40 CFR part 63, appendix A), you must identify the individual compounds that are present in the solvent mixture and use the weight fraction of those individual compounds and their RF from table 2A to this subpart in the calculation. (e) The Reactivity Factor (RF) is assigned according to paragraphs (e)(1) through (4): (1) If a VOC is used in a product and listed in table 2A, 2B, or 2C to this subpart, then the assigned RF shall be used; (2) If a product contains a mixture and/or multiple isomers of a VOC, the highest RF of the mixture or multiple isomers from table 2A to this subpart shall be used; (3) If a VOC is used in a product but not listed in table 2A to this subpart, but more than one isomer or mixtures of isomers of the VOC is listed in table 2A to this subpart, then the highest RF associated with the listed isomers or isomer mixtures shall be used; and (4) If a VOC is used in a product but not listed in table 2A to this subpart, the assigned default RF of 18.50 g O3
                             /g VOC shall be used. 
 (h) Until July 17, 2025 the test methods listed in table 3 of appendix A to subpart E of part 59 are applicable to this subpart.
 5.Revise § 59.508 to read as follows: § 59.508
  (a) Except as provided in § 59.505(c), you must use the procedures in CARB Method 310 (2018) (incorporated by reference, see § 59.515) or EPA's Method 311 (40 CFR part 63, appendix A) to determine the speciated ingredients and weight percentage of each ingredient of each aerosol coating product. EPA Method 311 (40 CFR part 63, appendix A) must be used in conjunction with ASTM Method D3063-94 or D3074-94 for analysis of the propellant portion of the coating. Those choosing to use CARB Method 310 (2018) must follow the procedures specified in section 5.0 of that method with the exception of section 5.3.1, which requires the analysis of the VOC content of the coating. For the purposes of this subpart, you are not required to determine the VOC content of the aerosol coating. For both CARB Method 310 (2018) and EPA Method 311 (40 CFR part 63, appendix A), you must have a listing of the VOC ingredients in the coating before conducting the analysis. (b) To determine the metal content of metallic aerosol coating products, you must use SCAQMD Method 318-95 (incorporated by reference, see § 59.515). (c) To determine the specular gloss of flat and non-flat coatings, you must use ASTM Method D523-08 (incorporated by reference, see § 59.515).

(l) If you are required to submit notifications or reports following the procedure specified in this paragraph (l), you must submit reports to the EPA via CEDRI, which can be accessed through the EPA's Central Data Exchange (CDX) (
                            *https://cdx.epa.gov/​*). The EPA will make all the information submitted through CEDRI available to the public without further notice to you. Do not use CEDRI to submit information you claim as confidential business information (CBI). Anything submitted using CEDRI cannot later be claimed CBI. You must use the appropriate electronic report template on the CEDRI website (
                            *www.epa.gov/​electronic-reporting-air-emissions/​cedri*) for this subpart. The date in which the report template becomes available will be listed on the CEDRI website. Unless the Administrator or delegated State agency or other authority has approved a different schedule for submission of reports, the report must be submitted by the deadline specified in this subpart, regardless of the method in which the report is submitted. Although we do not expect persons to assert a claim of CBI, if you wish to assert a CBI claim, submit a complete report, including information claimed to be CBI, to the EPA. The report must be generated using the appropriate template on the CEDRI website. The preferred method for CBI submittal is for it to be transmitted electronically using email attachments, File Transfer Protocol (FTP), or other online file sharing services. Electronic submissions must be transmitted directly to the OAQPS CBI Office at the email address: 
                            *oaqpscbi@epa.gov*
                             and should include clear CBI markings and be flagged to the attention of the Group Leader, Measurement Policy Group. If assistance is needed with submitting large electronic files that exceed the file size limit for email attachments, and if you do not have your own file sharing service, please email 
                            *oaqpscbi@epa.gov*
                             to request a file transfer link. If you cannot transmit the file electronically, you may mail the electronic medium to U.S. EPA/OAQPS/CORE CBI Office, Attention: Aerosol Coatings Sector Lead, (C404-02), Research Triangle Park, North Carolina 27711. The same file with the CBI omitted must be submitted to the EPA via the EPA's CDX as described earlier in this paragraph (l). All CBI claims must be asserted at the time of submission. Furthermore, under CAA section 114(c), emissions data is not entitled to confidential treatment, and the EPA is required to make emissions data available to the public. Thus, emissions data will not be protected as CBI and will be made publicly available. (m) If you are required to electronically submit a report through CEDRI in the EPA's CDX, you may assert a claim of EPA system outage for failure to timely comply with that reporting requirement. To assert a claim of EPA system outage, you must meet the requirements outlined in paragraphs (m)(1) through (7) of this section. (1) You must have been or will be precluded from accessing CEDRI and submitting a required report within the 
                            ( print page 5709)

(2) The outage must have occurred within the period of time beginning five business days prior to the date that the submission is due. (3) The outage may be planned or unplanned. (4) You must submit notification to the Administrator in writing as soon as possible following the date you first knew, or through due diligence should have known, that the event may cause or has caused a delay in reporting. (5) You must provide to the Administrator a written description identifying: (i) The date(s) and time(s) when CDX or CEDRI was accessed, and the system was unavailable; (ii) A rationale for attributing the delay in reporting beyond the regulatory deadline to EPA system outage; (iii) A description of measures taken or to be taken to minimize the delay in reporting; and (iv) The date by which you propose to report, or if you have already met the reporting requirement at the time of the notification, the date you reported. (6) The decision to accept the claim of EPA system outage and allow an extension to the reporting deadline is solely within the discretion of the Administrator. (7) In any circumstance, the report must be submitted electronically as soon as possible after the outage is resolved. (n) If you are required to electronically submit a report through CEDRI in the EPA's CDX, you may assert a claim of force majeure for failure to timely comply with that reporting requirement. To assert a claim of force majeure, you must meet the requirements outlined in paragraphs (n)(1) through (5) of this section. (1) You may submit a claim if a force majeure event is about to occur, occurs, or has occurred or there are lingering effects from such an event within the period of time beginning five business days prior to the date the submission is due. For the purposes of this section, a force majeure event is defined as an event that will be or has been caused by circumstances beyond the control of the regulated entity, its contractors, or any entity controlled by the regulated entity that prevents you from complying with the requirement to submit a report electronically within the time period prescribed. Examples of such events are acts of nature (
                            *e.g.,*
                             hurricanes, earthquakes, or floods), acts of war or terrorism, or equipment failure or safety hazard beyond the control of the regulated entity (
                            *e.g.,*
                             large scale power outage). (2) You must submit notification to the Administrator in writing as soon as possible following the date you first knew, or through due diligence should have known, that the event may cause or has caused a delay in reporting. (3) You must provide to the Administrator: (i) A written description of the force majeure event; (ii) A rationale for attributing the delay in reporting beyond the regulatory deadline to the force majeure event; (iii) A description of measures taken or to be taken to minimize the delay in reporting; and (iv) The date by which you propose to report, or if you have already met the reporting requirement at the time of the notification, the date you reported. (4) The decision to accept the claim of force majeure and allow an extension to the reporting deadline is solely within the discretion of the Administrator. (5) In any circumstance, the reporting must occur as soon as possible after the force majeure event occurs.
