Approval and Promulgation of Implementation Plans and Operating Permits Program; State of Nebraska

EPA is approving revisions to the State Implementation Plan (SIP) and Operating Permits Programs submitted by the state of Nebraska. This action revises monitoring requirements which were found to be less stringent than the applicable Federal rule; adds permits-by- rule provisions, which would provide a streamlined approach for issuing construction/operating permits for hot mix asphalt plants and small animal incinerators; and deletes the chemical compound ethylene glycol monobutyl ether from the list of regulated hazardous air pollutants in Appendices II and III. Approval of these revisions will ensure consistency between the state and Federally-approved rules, and ensure Federal enforceability of the state's revised air program rules.
