Coal Handling Preparation Plants (CHPP) are large facilities used to remove (wash) the grime and sediment (soil, rock, etc) from coal in order to prepare it to be transported to market. The cleaner the coal is able to become, the higher the market value will be, plus less waste material means less weight, resulting in lower overall transportation costs.
