The US Environmental Protection Agency (EPA) has issued a final rule setting the first standards that will reduce emissions of formaldehyde, benzene, acrolein and other toxic air pollutants from certain stationary diesel engines. The emission limits apply to existing diesel engines meeting certain criteria for age, size, and use.
