On December 7, 2009, the Environmental Protection Agency (“EPA”) promulgated its long-awaited endangerment finding.  Evidently timed to coincide with the beginning of the international climate change negotiations in Copenhagen, the Agency’s finding states that elevated atmospheric concentrations of six greenhouse gases (“GHGs”) emitted by man – carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride – are contributing to dangerous climate change. 

On December 3, 2009, the Federal Energy Regulatory Commission (“FERC” or the “Commission”) denied Clipper Windpower Development Company, Inc.’s (“Clipper Windpower”) emergency motion and request for temporary waiver of part of the California Independent System Operator Corporation’s (“CAISO”) Large Generator Interconnection Procedures (“LGIP”).  In its motion, Clipper Windpower argued that the current security deposit requirements within CAISO’s LGIP would force it to post a $7.5 million deposit for upgrades that would cost approximately $4.6 million.

The U.S. Surface Transportation Board (“STB”) on December 1, 2009 instituted a formal proceeding to examine tariff rules established by the BNSF Railway Company (“BNSF”) that limit the amount of coal dust that can be emitted by trains transporting coal over certain railroad lines leaving the Powder River Basin (“PRB”).
