Where must burial at sea occur in relation to the shoreline?

Burial at sea is regulated by federal law in the United States, specifically under the Marine Protection, Research, and Sanctuaries Act. According to this law, the burial must take place at least three nautical miles (which is approximately 3.45 statute miles) from the nearest shoreline. This distance is significant as it helps to ensure that the burial does not pose a threat to marine life or negatively impact coastal water quality. Therefore, the correct answer reflects the legal requirement that burial at sea must occur at a distance of at least three miles from the shoreline. Understanding this regulation is crucial for funeral directors and those involved in arranging such services to ensure compliance with relevant laws and guidelines.
