OSHA expects a response from dam officials by the end of the month, OSHA spokeswoman Deanne Amaden said. She added that Bureau of Reclamation officials can seek time to correct violations.
Davis said inspectors initially told dam operations supervisors they found 77 violations. Some included improper location of fire extinguishers and placement of extension cords. Some two dozen were quickly corrected, Davis said.
Other shortcomings, such as doors opening the wrong direction, date from the construction of the dam in the 1930s, Davis said.
Atha said eight violations were designated as repeat offenses because OSHA has previously notified the Bureau of Reclamation within the past five years of a similar violation at Hoover Dam or another bureau facility in the OSHA region including California, Nevada, Arizona, Hawaii and the Pacific.
