45950 Federal Register / Vol. 86, No. 156 / Tuesday, August 17, 2021 / Proposed Rules 

IV. What action is EPA taking? 

EPA is proposing to approve EGLE’s 

request for a Clean Data Determination 

for the St. Clair nonattainment area in 

St. Clair County, Michigan. Finalizing 

this determination would suspend the 

requirements for EGLE to submit an 

attainment demonstration and other 

associated nonattainment planning 

requirements for so long as the St. Clair 

nonattainment area continues to attain 

the 2010 SO2 NAAQS. This proposed 

action is consistent with EPA’s longheld interpretation of CAA 

requirements. 

Finalizing this action would not 

constitute a redesignation of the St. 

Clair area to attainment of the 2010 SO2

NAAQS under section 107(d)(3) of the 

CAA. The St. Clair area will remain 

designated nonattainment for the 2010 

SO2 NAAQS until such time as EPA 

determines that the area meets the CAA 

requirements for redesignation to 

attainment and takes action to 

redesignate the area. 

V. Statutory and Executive Order 

Reviews 

This action proposes to make a clean 

data determination for the St. Clair area 

for the 2010 SO2 NAAQS based on air 

quality data which would result in the 

suspension of certain Federal 

requirements and does not impose any 

additional requirements. For that 

reason, this 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 CAA; and 

• Does not provide EPA with the 

discretionary authority to address, as 

appropriate, disproportionate human 

health or environmental effects, using 

practicable 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 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).
