Proposed Rulemaking for Issuance of a Letter of Authorization and an Incidental Harassment Authorization for the Take of Marine Mammals Incidental to the Don Young Port of Alaska’s Cargo Terminals Replacement (CTR) Project in Anchorage, Alaska

EA for issuance of Incidental Take Regulations and associated LOA for construction work at the Port of Alaska Cargo Terminals. This project includes impact and vibratory pile driving of steel pipe piles during April - November 2026 - 2030, and a potential IHA for a sixth year of in-water work (2031). This project has the potential to take Cook Inlet beluga whales by Level B harassment, at numbers approaching the 33% small numbers threshold each year. The CIBW is a species in the spotlight and several NGOs have commented on previous Cook Inlet projects.
