The Environmental Protection Agency (EPA) issued an Advance Notice of Proposed Rulemaking (ANPRM) seeking comment on control of emissions of air pollution from
new locomotive engines and new marine compression-ignition engines less than 30 liters per cylinder. The emphasis is on achieving large reductions in emissions of particulate matter (PM) and air toxics through use of advanced emission control technology. This will be made possible, in part, through use of diesel fuel with sulphur content capped at 15 parts per million (ppm). Comments on this proposal should be submitted by August 30, 2004. 69 Fed. Reg. 39275 (HK Law).
