§1421c Unusual Mortality Event Response

Title 16 › Chapter 31— MARINE MAMMAL PROTECTION › Subchapter V— MARINE MAMMAL HEALTH AND STRANDING RESPONSE › § 1421c

Last updated Apr 5, 2026|Official source

Summary

The Secretary must set up a team of experts, working with the Secretary of the Interior, to help decide when lots of marine mammals are dying and how to respond. The team must include people with marine science, veterinary, conservation, and medical experience. If someone in a stranding network reports a possible event, the Secretary must try to contact as many team members as possible within 24 hours. Within 48 hours the Secretary must decide if an unusual mortality event is happening, tell the reporter, and, if needed, name an Onsite Coordinator to run the field response. The Secretary must also write a public contingency plan for these events. The plan must list people and groups who can help, say what tissues and tests are needed, explain training and mobilization steps, and set rules to reduce deaths, find causes, measure effects on populations, and check physical, chemical, and biological factors (including contaminants). Onsite Coordinators are usually regional officials or their designees and may be more than one; one can be given primary responsibility. Coordinators lead and direct responders under the plan, use professional judgment for things not covered, can briefly change the plan after quick consultation, and may delegate authority. Working group = expert advisers; stranding network participant = someone who reports stranded marine mammals; Onsite Coordinator = person who leads the response; contingency plan = the written response steps.

(a)(1)(A)The Secretary, acting through the Office, shall establish, in consultation with the Secretary of the Interior, a marine mammal unusual mortality event working group, consisting of individuals with knowledge and experience in marine science, marine mammal science, marine mammal veterinary and husbandry practices, marine conservation, and medical science, to provide guidance to the Secretary and the Secretary of the Interior for—
(i)determining whether an unusual mortality event is occurring;
(ii)determining, after an unusual mortality event has begun, if response actions with respect to that event are no longer necessary; and
(iii)developing the contingency plan in accordance with subsection (b), to assist the Secretary in responding to unusual mortality events.
(B)Chapter 10 of title 5 shall not apply to the marine mammal unusual mortality event working group established under this paragraph.
(2)The Secretary, in consultation with the Secretary of the Interior, shall to the extent necessary and practicable—
(A)within 24 hours after receiving notification from a stranding network participant that an unusual mortality event might be occurring, contact as many members as is possible of the unusual mortality event working group for guidance; and
(B)within 48 hours after receiving such notification—
(i)make a determination as to whether an unusual mortality event is occurring;
(ii)inform the stranding network participant of that determination; and
(iii)if the Secretary has determined an unusual mortality event is occurring, designate an Onsite Coordinator for the event, in accordance with subsection (c).
(b)(1)The Secretary shall, in consultation with the Secretary of the Interior and the unusual mortality event working group, and after an opportunity for public review and comment, issue a detailed contingency plan for responding to any unusual mortality event.
(2)The contingency plan required under this subsection shall include—
(A)a list of persons, including stranding network participants, at a regional, State, and local level, who can assist the Secretary in implementing a coordinated and effective response to an unusual mortality event;
(B)the types of marine mammal tissues and analyses necessary to assist in diagnosing causes of unusual mortality events;
(C)training, mobilization, and utilization procedures for available personnel, facilities, and other resources necessary to conduct a rapid and effective response to unusual mortality events; and
(D)such requirements as are necessary to—
(i)minimize death of marine mammals in the wild and provide appropriate care of marine mammals during an unusual mortality event;
(ii)assist in identifying the cause or causes of an unusual mortality event;
(iii)determine the effects of an unusual mortality event on the size estimates of the affected populations of marine mammals; and
(iv)identify any roles played in an unusual mortality event by physical, chemical, and biological factors, including contaminants.
(c)(1)(A)The Secretary shall, in consultation with the Secretary of the Interior, designate one or more Onsite Coordinators for an unusual mortality event, who shall make immediate recommendations to the stranding network participants on how to proceed with response activities.
(B)An Onsite Coordinator so designated shall be one or more appropriate Regional Directors of the National Marine Fisheries Service or the United States Fish and Wildlife Service, or their designees.
(C)If, because of the wide geographic distribution, multiple species of marine mammals involved, or magnitude of an unusual mortality event, more than one Onsite Coordinator is designated, the Secretary shall, in consultation with the Secretary of the Interior, designate which of the Onsite Coordinators shall have primary responsibility with respect to the event.
(2)(A)An Onsite Coordinator designated under this subsection shall coordinate and direct the activities of all persons responding to an unusual mortality event in accordance with the contingency plan issued under subsection (b), except that—
(i)with respect to any matter that is not covered by the contingency plan, an Onsite Coordinator shall use his or her best professional judgment; and
(ii)the contingency plan may be temporarily modified by an Onsite Coordinator, consulting as expeditiously as possible with the Secretary, the Secretary of the Interior, and the unusual mortality event working group.
(B)An Onsite Coordinator may delegate to any qualified person authority to act as an Onsite Coordinator under this subchapter.
