Coal is safe, inert and has been transported safely for more than 40 years.

The International Agency for Research on Cancer does not include coal dust on its list of carcinogenic agents harmful to humans.

In Montana, a review of a 2012 Missoula City-County Health Department coal dust study confirmed it is unlikely that coal dust emissions generated by the transportation of coal by railway will have health impacts on the public.

In 2013, Delta conducted monitoring to investigate the presence of coal dust in the community. Results showed that there was limited coal dust, even in the driest month on record.
Marine.

In March 2014, the Northwest Clean Air Agency – which enforces government clean air standards in the U.S. Pacific Northwest – released a study which indicated that after a year’s worth of monitoring, coal dust is simply not a cause for concern.
