The National Marine Fisheries Service (NMFS) has issued an incidental harassment authorization (IHA) to the Washington State Department of Transportation (WADOT) for the Purdy Bridge Rehabilitation Project in Pierce County, Washington. This authorization allows for the incidental harassment of marine mammals during construction activities that involve pile driving and removal, which may disturb these animals through noise. However, no serious injury or death of marine mammals is anticipated. The NMFS has set specific measures to minimize impacts, ensuring that the activity complies with the Marine Mammal Protection Act and does not harm the animals or their environment significantly.
Simple Explanation
The people in charge of ocean animals said it's okay for builders to make loud noises while fixing a bridge, even if it might bother some sea creatures like whales or seals a bit, but they promise not to hurt them.
