NDEP BAPC proposes to revise Class II Air Quality Operating Permit AP1442-0823.05 for 3D Concrete LLC / Dayton Materials, a concrete manufacturing facility. The proposed action includes modifications to existing permit terms and conditions. Supporting documents available include the Director's Review and Draft Permit. The notice does not specify the nature of the permit modifications being requested.

The public comment period runs from April 1, 2026 through May 1, 2026. Interested parties should download the Notice of Proposed Action, Director's Review, and Draft Permit documents from the NDEP website. Written comments must be submitted by May 1, 2026. While this is a permit-level action rather than a rulemaking, facilities operating similar emissions sources should monitor this proceeding as it may indicate evolving permit conditions and BAPC interpretation of Class II AQOP requirements in Nevada.
