NEW  REGULATORY ADVISORY FOR REPORTING 2015 DATA.  The California Air Resources Board (ARB) is granting an extension to June 8, 2016, for electric power entities and abbreviated reporters that did not complete the submission and certification of their GHG emissions data report prior to May 27, 2016. The extension is being provided because of an unforeseen technical issue with Cal e-GGRT which disabled the reporting system for a period of time beginning on the morning of May 27, 2016. Cal e-GGRT is currently fully operable and the technical issues have been remedied.  See the full Regulatory Advisory for additional information. (Added 5/31/2016)
