Coal breakers also remove impurities from the coal (typically slate) and deposit them into a culm dump. The coal breaker is a forerunner of the modern coal preparation plant. Generally speaking, a coal tipple was typically used at a bituminous coal mine, where removing impurities was important but sorting by size was only a secondary, minor concern.

The Carbon Principles The Carbon Principles The Carbon Principles are a series of guidelines established by three leading Wall Street banks — Citigroup Inc., JP Morgan Chase, and Morgan Stanley — to assess the risks in financing electric power projects in terms of climate change. These principles call for "enhanced diligence" in evaluating electric power industry borrowers in terms of their use of energy efficiency; renewable and low-carbon distributed energy technologies; and conventional and advanced generating technologies. These guidelines were announced in February 2008 to address the increasing public concern over the plans to create over one hundred coal power plants in the
