A federal court of appeals has overturned a US Environmental Protection Agency (EPA) rule allowing backup generators to run for 100 hours per year without being subject to air pollution controls.
Last week the U.S Court of Appeals for the District of Columbia Circuit ruled that the EPA has failed to justify the exemption for diesel-fueled backup generators.
In 2010 the EPA started to allow backup generators to run for up to 15 hours a year without being subject to emissions regulations. By January 2013 the agency updated those rules, allowing the backup generators to run for 100 hours.
The rule was challenged by the Delaware Department of Natural Resources backed by a number of environmental advocacy groups and power suppliers, arguing that the 100-hour rule could encourage large consumers to use more power from backup generators in non-emergency situations.
