Supplementary Information
On January 2, 2026, the EPA published the [[Page 2895]] notice of proposed rulemaking (NPRM) ``Proposed Revisions of the Nonattainment Designation for the 2008 and 2015 Ozone Standards and Clean Data Determinations for the 2008 and 2015 Ozone Standards: Cecil County, MD and New Castle County, DE'' in the Federal Register (91 FR 98). The NPRM specified that the comment period would end on February 2, 2026. However, the EPA's Technical Support Document (TSD), identified in the docket as ``MD DE 107 TSD Final'', was not made available in the docket until January 5, 2026 (three days after publication). To ensure the public and interested parties have sufficient time to review the associated docket materials and submit comment on the NPRM, the EPA is extending the comment period by a week to February 9, 2026.
