A marine park wishing to capture or import a marine mammal must file an application, under one of the listed exemptions, with NMFS. The application must list the number and species of animals involved, the method of capture (which must be "humane"), the names and qualifications of personnel involved in the capture or transport, and the impact the capture may have on the wild population. The application is then published in the Federal Register and open for public comment for 30 days. NMFS usually makes a decision on the application within four or five months. The most recent amendments to the MMPA in 1994 stripped NMFS of its authority to deny applications to export marine mammals or transport them among states. Previously, animal owners wishing to sell or transport animals had to submit an application to NMFS showing that the facility to which the animals were being transferred and the method of transport were acceptable under standards set by the Animal Welfare Act (see below). The 1994 amendments changed the requirements so that the individual seeking to transfer animals need only file a letter with NMFS stating that the procedures and facilities meet the standard. NMFS no longer has authority to deny these applications or inspect or oversee the destination facilities.
