The Centralia power plant in Washington contributes 10 percent of the state's total greenhouse gases, but not for much longer. The coal mine closed in 2006—the last of the state's mines to be shuttered—and then in 2011, TransAlta reached a deal with the state to shut down the plant. It will convert its former mine site to a solar farm.

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

COAL HANDLING SAFETY Risks of unwanted combustion – potentially causing injury, damage and downtime – occur everywhere that coal is handled, processed or stored. Safe coal handling practices are designed to ensure that the fuel remains intact throughout its journey from the mine until the point at which it is ignited in the boiler.
