The U.S. Environmental Protection Agency (EPA) is adopting standards that will dramatically reduce emissions of diesel particulate matter (PM) and nitrogen oxide (NOx) from locomotives and marine diesel engines. This three-part program aims to:

Tighten emissions standards for existing locomotives and large marine diesel engines when they are remanufactured;
Set near-term engine-out emissions standards — referred to as Tier 3 standards — for newly built locomotives and marine diesel engines; and
Set longer-term standards — referred to as Tier 4 standards — for newly built locomotives and marine diesel engines that reflect the application of high-efficiency aftertreatment technology.

EPA is also finalizing new idle reduction requirements for newly built and remanufactured locomotives and adopting provisions to encourage a new generation of clean switch locomotives based on clean, nonroad diesel engine standards. This rule completes an important step in EPA’s ongoing National Clean Diesel Campaign (NCDC).

EPA estimates 90% PM reductions and 80% NOx reductions from Tier 4 engines meeting these standards, compared to engines meeting the current Tier 2 standards. By 2030, this program will reduce annual emissions of NOx by about 800,000 tons and PM emissions by 27,000 tons and those emission reductions continue to grow beyond 2030 as fleet turnover is completed.

The final requirements will bring earlier and significantly greater emission reductions of NOx and PM from the locomotive and marine sector than the proposed program envisioned. This is accomplished by finalizing the first-ever national standards for remanufactured large commercial marine diesel engines (above 600 kW) and starting Tier 4 NOx requirements for line-haul locomotives and for the largest (2,000-3,700 kW) marine engines two years earlier than initially proposed. These changes reflect important cooperative efforts by the regulated industry to implement cleaner technology as early as possible and will provide communities across the United States with crucial emissions reductions both in the near term and long term.
