What the agency says
The Environmental Protection Agency (EPA) is making an interim final determination that the California Air Resources Board (CARB) has submitted a revised rule on behalf of the Eastern Kern Air Pollution Control District (EKAPCD) that addresses deficiencies in its Clean Air Act (CAA or "Act") State Implementation Plan (SIP) concerning reasonably available control technology (RACT) ozone nonattainment requirements for controlling emissions of oxides of nitrogen (NO<INF>X</INF>) from Portland cement kilns. This determination is based on a proposed approval of the submitted revised rule, published elsewhere in this issue of the Federal Register. The effect of this interim final determination is that the application of offset sanctions that was triggered by a previous limited disapproval by the EPA in 2023 is now stayed, and the application of highway sanctions is now deferred. If the EPA finalizes its proposed approval of EKAPCD's submittal, relief from these sanctions will become permanent.
