5. Title, number of pages and language(s) of the notified document:  Heavy-Duty 
Engine and Vehicle, and Non-road Technical Amendments (14 pages, in English).     
6. Description of content:  EPA is proposing to amend provisions in the Medium- and 
Heavy- Duty Greenhouse Gas Emissions and Fuel Efficiency final rule issued on 15 September 2011. These proposed amendments  would eliminate duplicative reporting 
requirements, reduce inadvertent minor differences between the EPA and NHTSA 
programs regarding such matters as voluntary early model year compliance, better align testing procedures to market realities, an d reduce unnecessary testing burdens. EPA is 
also proposing to amend several regulations by: Adjusting the provisions of the 
replacement engine exemption; expanding EPA's discretion to allow greater flexibility under the Transition Program for Equipment Manufacturers related to the Tier 4 standards for non-road diesel engines; specifying multiple versions of the applicable SAE 
standard for demonstrating that fuel lines for non-road spark-ignition engines above 19 
kilowatts meet permeation requirements; and allowing for the use of the ethanol-based test fuel specified by the California Air Resources Board for non-road spark-ignition 
engines at or below 19 kilowatts. Some of the individual provisions of this action may 
have minor impacts on the costs and emission reductions of the underlying regulatory programs amended in this action, though in most cases these are simple technical 
amendments. For those provisions that may have a minor impact on the costs or 
benefits of the amended regulatory program, any potential impacts would be small and we have not attempted to quantify the potential changes. 
7. Objective and rationale, including the nature of urgent problems where 
applicable:  Protection of the environment.
