proposing changes to the test procedures for heavy -duty engines and vehicles to improve 
accuracy and reduce testing burden. EPA is also proposing other regulatory amendments 
concerning light -duty vehicles, heavy -duty vehicles, highway motorcycles , locomotives, 
marine engines, other nonroad engines and vehicles, stationary engines. These would 
affect the certification procedures for exhaust emission standards, and related 
requirements. EPA is proposing similar amendments for evaporative emission st andards for 
nonroad equipment and portable fuel containers. These amendments would increase 
compliance flexibility, harmonize with other requirements, add clarity, correct errors, and 
streamline the regulations. Given the nature of the proposed changes, th ey would have 
neither significant environmental impacts nor significant economic impacts for any sector.  G/TBT/N/USA/1620
