Staff Report for Stationary Diesel ATCM

For example, an uncontrolled 1988 500hp diesel engine could have a PM emission rate of over 0.5 g/bhp-hr, whereas a 2003 model year engine is required to meet a 0.15 g/bhp-hr emission rate and, under the proposed Tier 4 standards, that same size engine will be required to meet a 0.01 g/bhp-hr emission rate in the 2011-2014 timeframe. ................
