A harbor authority is a governmental or quasi-governmental organization responsible for managing and overseeing the operations of a harbor or port. Their main duties include ensuring the safety of navigation, maintaining port facilities, and facilitating trade and transportation. They often work to promote economic development in the surrounding area by attracting shipping and maritime businesses. Harbor authorities also play a crucial role in environmental protection and sustainability. They implement regulations to minimize pollution and protect marine ecosystems. Additionally, they may coordinate with other agencies, such as the U.S. Coast Guard or Environmental Protection Agency, to ensure compliance with safety and environmental standards.
