Safety zone
Safety zone means a safety zone established around a deepwater port under part 150, subpart J, of this chapter. The safety zone may extend to a maximum distance of 500 meters (approximately 1,640 feet) around the facility, measured from each point on its outer edge or from its construction site, except as authorized by generally accepted international standards or as recommended by the International Maritime Organization. However, the zone may not interfere with the use of recognized sea lanes.
