摘要

SNMFS has received an application from the California Department of Transportation (Caltrans) for an Incidental Harassment Authorization (IHA) to take marine mammals, by Level B harassment, incidental to retrofitting the Dumbarton Bridge, located in southern San Francisco Bay (Bay), California. Pursuant to the Marine Mammal Protection Act (MMPA), NMFS is requesting comments on its proposal to issue an IHA to Caltrans to incidentally harass harbor seals (Phoca vitulina richardii), California sea lions (Zalophus californianus), and gray whales (Eschrichtius robustus) during the specified activity.
