Coal Preparation and Processing Plants New Source Performance Standards (NSPS)

On this page:

Rule Summary

On September 25, 2009, the Environmental Protection Agency (EPA) revised emissions control requirements for new coal preparation and processing plants. Those new performance standards were designed to further reduce emissions at new coal preparation and processing plants that process more than 200 tons of coal per day.

Coal preparation and processing plants break, crush, screen, clean and/or use heat to dry coal at coal mines, power plants, cement plants, coke manufacturing facilities, and industrial facilities. New coal preparation and processing plants were required to install controls or utilize work practices to meet the amended limits. EPA estimated that this final rule would reduce 7,600 tons per year of PM emissions from new coal-handling equipment.

EPA also estimated total nationwide annual costs of $7.9 million when the revised standards are fully implemented. Included in those costs were costs of control technology necessary to meet the emission standards, and costs associated with the testing, monitoring, and recordkeeping and reporting requirements of the final rule.
