SeaWorld and California regulators said on Wednesday they have reached a settlement over allegations that the marine park did not properly train its employees to interact with its famed killer whales.

Four citations, with combined possible fines of up to $25,770, were issued in April by the California Division of Occupational Safety and Health against the San Diego amusement park.

SeaWorld trainers have not been in the water with the killer whales during shows since 2010, when a trainer at its Orlando, Florida, park was killed by an orca during a performance.
