receptors in Connecticut, which are 2,263 and 2,285 miles away, respectively.42 Californias contribution to these monitors is 0.03 ppb to both the nonattainment and maintenance-only receptors in 2021, which represents the maximum contribution of California to any nonattainment and maintenanceonly receptor in Connecticut. This is well below the threshold of 1 percent of the NAAQS that would link the two states, triggering further review in steps 3 and 4 of the interstate transport analysis framework. Given that the distance between California and Connecticut is comparable to the distance between Hawaii and California, and ozone precursor emissions from California are more than 10 times larger than ozone precursor emissions from Hawaii, because Californias contributions to Connecticut are well below the 1 percent threshold, it is reasonable to conclude that Hawaiis contribution to California would also be below the 1 percent threshold.
Therefore, it is not necessary to evaluate potential NOX reductions as part of step 3 in the EPAs four-step interstate transport framework.
Based on the weight of evidence, including 1 the distance between Hawaii and California, 2 the relative magnitude of ozone precursor emissions from Hawaii, 3 the predominant wind direction of the trade winds in Hawaii, and 4 the comparison to the impact of ozone precursor emissions from California on Connecticut, we propose to find that Hawaii will not significantly contribute to nonattainment or interfere with maintenance in any other state.
IV. The EPAs Proposed Action Based on our review of the interstate transport SIP submission from HDOH to address the 2015 ozone NAAQS and the additional analysis discussed in this document, we propose to find that emissions from Hawaii will not significantly contribute to nonattainment or interfere with maintenance of the 2015 ozone NAAQS
in any other state. Accordingly, we propose to approve the HDOH Submittal as satisfying the requirements of CAA
section 110a2DiI for the 2015
ozone NAAQS.

federal regulations. 42 U.S.C. 7410k;
40 CFR 52.02a. Thus, in reviewing SIP
submissions, the EPAs 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. 1044;
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 12d 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

Arizona: Authorization of State Hazardous Waste Management Program Revisions Environmental Protection Agency EPA.
ACTION: Proposed action/decision/
authorization.
AGENCY:

The Environmental Protection Agency EPA is proposing to authorize changes to Arizonas hazardous waste program under the Resource Conservation and Recovery Act RCRA.
These changes were outlined in an application to the EPA and correspond to certain Federal rules promulgated between July 1, 2007 and June 30, 2020.
The EPA reviewed Arizonas application and has determined that these changes satisfy all requirements needed to qualify for final authorization.
Therefore, in the Rules and Regulations section of this Federal Register, we are authorizing Arizona for these changes as a direct final authorization without a prior proposed action. If we receive no adverse comment, we will not take further action on this proposed authorization.
DATES: Comments must be received on or before October 28, 2021.
