Projects must include one or more of the following diesel emissions reduction solutions that use a certified engine configuration and/or verified technology. 1. Vehicle and Equipment Replacements: Off-road diesel vehicles and equipment, locomotives, and marine vessels can be replaced with newer, cleaner vehicles and equipment. Eligible replacement vehicles and equipment include those powered by diesel or clean alternative fuel engines (including gasoline), electric generators (gensets), hybrid engines, and zero tailpipe emissions power sources (grid, battery or fuel cell). To be eligible for funding, vehicles and equipment must be powered by engines certified by EPA and, if applicable, California Air Resources Board (CARB) emission standards. Zero tailpipe emissions vehicles and equipment do not require EPA or CARB certification. EPA’s annual certification data for vehicles, engines, and equipment may be found at: https://www.epa.gov/compliance-and-fuel-economydata/annual-certification-data-vehicles-engines-and-equipment. EPA’s engine emission standards may be found at: www.epa.gov/emission-standards-reference-guide/all-epa-emission-standards. Engines certified by CARB may be found by searching CARB’s Executive Orders for Heavy-duty Engines and Vehicles, found at: www.arb.ca.gov/msprog/onroad/cert/cert.php. Please see the Low-NOx Engine Factsheet found at www.epa.gov/dera/state for guidance on identifying engines certified to meet CARB’s Optional Low NOx Standards. 2. Engine Replacements: Off-road diesel vehicles and equipment, locomotives, and marine vessels can have their engines replaced with newer, cleaner engines. Eligible replacement engines include those certified for use with diesel or clean alternative fuel (including gasoline), electric generators (gensets), hybrid engines, and zero tailpipe emissions power sources (grid, battery or fuel cell)...
