Emissions Control Requirement

Heavy-duty diesel vehicles used to perform federally funded state public works contracts must be powered by engines with Level 3 emissions control devices that are properly operated and maintained. If the Rhode Island Department of Environmental Management determines that no verified Level 3 devices are appropriate on particular engines, Level 2 devices are required. Likewise, if no verified Level 2 devices are appropriate, Level 1 devices are required. Exceptions to this requirement include, but are not limited to, snow removal vehicles and equipment, farm equipment, emergency response vehicles, standby generators, and vehicles used on a project for less than 30 total work days over the life of the project.
