H.R. 10776 — To amend the Marine Mammal Protection Act of 1972 to change certain requirements regarding certain allowed take of marine mammals, and for other purposes.

This section revises the definition of harassment under the Marine Mammal Protection Act to require actual injury or disturbance of marine mammals rather than the potential for such effects. It removes the "small numbers" limitation on incidental take authorizations, adjusts the required conditions and monitoring to those the Secretary determines practicable and economically feasible, and bars any condition from altering the basic design, location, scope, duration, or timing of the activity. It also adds a definition of negligible impact and requires all decisions under the Act to rest solely on the objective application of the best scientific and commercial data available without precautionary factors.
