addresses visible emissions from dieselpowered motor vehicles. Visible emissions from diesel-powered motor vehicles are addressed in the state statute.

DATES: This final rule is effective on July 26, 2021.

I. What is being addressed in this document?
The EPA is amending Nebraskas SIP
to include revisions to title 129 of the Nebraska Administrative Code. The EPA
is approving revisions to the Nebraska SIP received on July 16, 2020.
Specifically, the EPA is amending the Nebraska SIP by removing a portion of the SIP as follows: Title 129. Chapter 39.
Visible Emissions from Diesel-powered Motor Vehicles. EPA is approving these revisions as they do not substantively change any existing statutory or regulatory requirement. These revisions do not impact the stringency of the SIP

or air quality. The EPA solicited comments on the proposed revision to Nebraskas SIP, and received no comments.
II. Have the requirements for approval of a SIP revision been met?
The state submission has met the public notice requirements for SIP
submissions in accordance with 40 CFR
51.102. The submission also satisfied the completeness criteria of 40 CFR part 51, appendix V. The State provided public notice of the SIP revision from September 28, 2019, to November 6, 2019, and held a public hearing on November 7, 2019. In a letter to the state dated November 7, 2019, the EPA stated that the agency has no comment on the proposed repeal of this regulation. EPA
further recommended that NDEE
include a justification that the rule is redundant to state statute. The SIP
revision meets the substantive requirements of the CAA, including section 110 and implementing regulations.
III. What action is the EPA taking?
The EPA is taking final action to amend the Nebraska SIP by approving the States request to remove Title 129
section 39. Visible Emissions from Diesel-powered Vehicles. The removal of this portion of the SIP will ensure consistency between state and federallyapproved rules. The EPA has determined that these changes will not adversely impact air quality because the regulation duplicates the States statute, which applies in the same jurisdiction.
IV. Incorporation by Reference In this document, the EPA is amending regulatory text that includes incorporation by reference. As described in the amendments to 40 CFR part 52 set forth below, the EPA is removing provisions of the EPA-Approved Nebraska Regulations from the Nebraska State Implementation Plan, which is incorporated by reference in accordance with the requirements of 1 CFR part 51.
V. Statutory and Executive Order Reviews Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the CAA and applicable 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 CAA. Accordingly, this action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond
