## Abstract

EPA is issuing a direct final rule revising the definition of nonroad engines to include all diesel-powered engines used in agricultural operations in the State of California that are certified by the engine maker to meet the applicable nonroad emission standards. Our rule will consider such engines as nonroad engines without regard to whether these engines are portable or transportable or how long these engines remain in one fixed location at a farm.
