The Environmental Protection Agency (EPA) has approved a revision to the South Coast Air Quality Management District portion of the California State Implementation Plan (SIP) to reduce emissions of oxides of nitrogen (NOX) from on-road heavy-duty vehicles. This measure, named the South Coast Incentive Measure, includes commitments by the California Air Resources Board (CARB) to achieve specified emission reductions, ensure project compliance, and submit annual reports. The plan is enforceable under the Clean Air Act, allowing citizens and the EPA to take action if CARB fails to meet its commitments. The rule will become effective on February 16, 2021.
Simple Explanation
The EPA is letting California use a new plan to make the air cleaner by reducing pollution from big trucks, and they have to check and report every year to show they are doing it.
