(NRC) emergency declaration, was terminated later that same day. The electrical fault caused an arc flash, resulting in a minor burn of a plant worker who was in the room and was treated at a local hospital. On March 22, 2017, the Nuclear Regulatory Commission announced that it had initiated a special inspection into the failure of the electrical bus that resulted in the plant declaring an alert. 2008 Florida electricity blackout On February 26, 2008, both reactors were shut down due to the loss of off-site power during a widespread power outage in South Florida, affecting 700,000 customers. At least 2.5 million people were without power. The blackout was initially caused by an overheated voltage switch that soon caught fire in a power substation in Miami, 23 miles away from the plant. The fire occurred at 1:08 PM and caused an automatic shutdown of the power plant. This led to a domino effect that caused outages as far north as Daytona Beach and Tampa. Power was restored by 4:30 PM. The reason this malfunction caused such widespread outages is still under investigation. Walt Disney World Resort, Orlando International Airport, and Miami International Airport were among the places affected by the outage. David Hoffman, a nuclear supervisor at Turkey Point, resigned over the incident and was subsequently sued by Florida Power and Light for return of a bonus. Hoffman countersued, claiming he was pressured to restart the reactors while they were in a condition which in his judgment made it unsafe to do so. Upper management wanted the reactors restarted during xenon dead time, which would have led to the operators at the controls having to continuously step control rods to safely manage reactor output. Florida Power and Light responded to the allegation, claiming Hoffman's suit was "self-motivated". Ecology The site is home to a large wildlife preserve. Turkey Point has been a contributing force to the reclassification of the American crocodile from endangered to the less serious category of vulnerable. Cooling canals Instead of a cooling tower, the plant has a large five-by-two mile () network of canals covering nearly . Several problems have arisen from this, including pollution of nearby national parks or water supply, particularly the Biscayne Aquifer, issues with overheating, and radioactive material. Overheating in the canals twice caused the plant to shut down reactors in 2014. In September 2016, a controversial cleanup process began that
