Federal Register / Vol. 86, No. 117 / Tuesday, June 22, 2021 / Proposed Rules
reciprocating internal combustion engines, dryers, furnaces, and ceramic kilns that have uncontrolled actual NOX
emissions equal to or greater than five tpy that existed at major sources of NOX
as January 27, 2020. Sections II.A.6.v vii expand combustion process adjustment requirements to dryers, furnaces, and ceramic kilns. Sections II.A.6.b.viiiAC clarify and expand combustion adjustment frequency requirements, including dates for initial combustion process adjustments.
We propose to find that the revisions to Section II are consistent with CAA
requirements, and that they strengthen the SIP.
ii Section III
Section III provisions control emissions from specific major sources of VOC and/or NOX in the DMNFR area.
Section III.B.1. establishes emission
limits and associated monitoring, recordkeeping, and reporting MRR
requirements for stationary internal combustion engines at certain major sources to meet RACT. Section III.B.2.
sets forth flare requirements and Section III.B.3. establishes MRR requirements for specific emission points at certain major sources to meet RACT. Section III.B.4. requires certain major sources to submit RACT analyses to the Division.
We propose to find that the revisions to Sections III.B.1. through 4. strengthen the SIP and meet CAA requirements. We also propose to find that Sections III.B.1.
through 2. establishes RACT
requirements for certain major sources by incorporating federal regulations.
We propose to find that the revisions to Part E are consistent with CAA
requirements, and that they strengthen the SIP. We therefore propose to approve the changes in Part E.

VII. Proposed Action For the reasons expressed above, the EPA proposes to approve revisions to Sections II, XII, and XVIII of Reg. 7 from the States May 14, 2018 and May 8, 2019 submittals and Parts A through E
from the States May 13, 2020
