EPAs Multi-Tiered ApproachFor New Engines

Tier 1 and Tier 2emission standards currently applicable to new marine diesel engines

Tier 1 limits NOx emissions only, and applies to model years 2004 and

laterTier 2 limits NOx, CO, and PM, and applies to model years 2007 and later

Tier 3near term emission standards for existing engines

for most towboats, Tier 3 standards become effective in 2014

Tier 4long term emission standards for newly-built engines

for most of our towboats, Tier 4 standards become effective in 2016
