This Environmental Assessment (EA) addresses potential environmental effects that could result from the final FMCSA HOS regulations (Final Action). Any potential environmental consequences thereof are discussed pursuant to the National Environmental Policy Act (NEPA) and other relevant legal authorities. This EA serves as a concise public document with sufficient analysis to determine if the Final Action warrants preparation of an environmental impact statement (EIS), issuance of a Finding of No Significant Impact (FONSI), or withdrawal of the final rule. This document primarily examines impacts that could result from implementation of the final rule and compares such impacts to the No Action Alternative.
