NRG El Segundo Operations, Inc. Case Settles for $200,000

The Regulation for Reducing Sulfur Hexafluoride (SF6) Emissions from Gas Insulated Switchgear (SF6 –GIS Regulation) establishes limits on annual SF6 emission rates.  NRG operates a power plant in El Segundo, California, with ten gas insulated switchgear containing a total of 3,803 pounds of SF6.  NRG exceeded the 2012 annual emission limitation. In this matter ARB concluded there were a number of mitigating factors including: the fact that this was a first time violation and NRG cooperated fully with the investigation.  This case was settled on December 11, 2015, for $200,000.00: $150,000.00 will go to the Air Pollution Control Fund, which provides funding for projects and research to improve California's air quality; $50,000.00 will go to the Peralta Colleges Foundation to fund emission education classes conducted by participating California community colleges, under the California Council for Diesel Education and Technology (CCDET) program.
