40 CFR § 52.1424
Operating permits
June 9, 2020
Emission limitations and related provisions which are established in Nebraska operating permits as Federally enforceable conditions shall be enforceable by EPA. The EPA reserves the right to deem permit conditions not Federally enforceable. Such a determination will be made according to appropriate procedures and be based upon the permit, permit approval procedures, or permit requirement which do not conform with the operating permit program requirements or the requirements of EPA underlying regulations.
