Title: ●In-Use Emissions Testing for Nonroad Diesel Engines
Abstract: This rulemaking will establish a manufacturer-run, in-use emissions testing program for 2013 and later model year nonroad diesel engines used in non-road equipment. The new program will assess in-use gaseous and particulate exhaust emission rates from nonroad diesel engines using portable emission measurement systems. Manufacturers will monitor compliance with the applicable not-to-exceed emission standards by typically testing in-use diesel engines during normal operation. If potentially non-complying engines are identified, the manufacturer will test more engines for the purpose of determining if any further action is necessary. EPA will likewise evaluate the in-use emissions data to make independent determinations about the possible need to pursue further testing or to initiate remedial actions. The in-use test data will not only be used by EPA to assure that emission standards are being met, but also by manufacturers to improve their engine designs. This program will address a serious, long-standing need for real-world in-use testing data to gauge the performance of engine emission controls.
