A suspected oil leak at the Cook nuclear power plant in Michigan was actually an error in level readings.
In a report filed with the U.S. Nuclear Regulatory Commission (NRC), plant operator American Electric Power (AEP, NYSE: AEP) said the discrepancy was due to maintenance activities that caused as error in level indication and that no loss of fuel oil happened.
Workers at the Cook plant notified the NRC and the state of Michigan on August 21 that 8,700 gallons of fuel oil were suspected to have leaked somewhere on site. The level in the buried fuel oil storage tank for the Train B emergency diesel generator was found to have been lower than measurements taken 24 hours before. Offsite agencies have been notified that the event is being retracted.
