Nick Hutson gave an update on the new MATS (mercury and air toxics standard). MATS replaced CAMR (the Clean Air Mercury Rule) which never made it past the legal arguments and industrial and public review. However MATS is also undergoing a rough ride and the final version of the proposal was only signed on Nov 16th 2012. The latest version will be published in the Federal Register on Nov 30 with a 30 comment period. Following further public comment, the MATS SHOULD be finalised by March 2013. The MATS covers around 1,400 coal-fired units (>25 MW) at . . .
