U.S. Fish and Wildlife Service - Marine Mammal Protection Act Incidental Take Letter of Authorization (12-FD-h)

Information current as of 2019
Section 101(a)(5) of the Marine Mammal Protection Act (MMPA) authorizes the Fish and Wildlife Service (FWS) to issue incidental takes of marine mammals. Section 101(a)(5)(A) allows the FWS to issue a Letter of Authorization (LOA) for a term of five years or less for incidental takes that may cause death or serious injury to marine mammals. The LOA must be in accordance with specific regulations, called Incidental Take Regulations (ITRs), that prescribe permissible methods of taking and other means of effecting the least practicable adverse impact on the affected species. The ITRs are issued as part of the permitting process and apply specifically to the proposed activity. They are promulgated in the Final Rule, which is issued in advance of the LOA. The LOA process takes between 8 and 18 months and involves two comment periods, possible public hearings, and consultations. The LOA may also be used for multiyear or complex projects, even when there is no potential for death or serious injury to marine mammals.

12-FD-h.1 to 12-FD-h.3 – Application for Incidental Take Regulations (ITRs) and Associated Letter of Authorization (LOA)

50 CFR 18.27(d)(1) requires the developer to submit a written application for an LOA and ITRs to the FWS before it can consider authorizing a taking. The request must include the following information:

  • A description of the specific activity or class of activities that can be expected to result in incidental taking of marine mammals;
  • The dates and duration of such activity and the specific geographical region where it will occur;
  • Based upon the best available scientific information;
    • An estimate of the species and numbers of marine mammals likely to be taken by age, sex, and reproductive conditions, and the type of taking (e.g., disturbance by sound, injury or death resulting from collision, etc.) and the number of times such taking is likely to occur;
    • A description of the status, distribution, and seasonal distribution (when applicable) of the affected species or stocks likely to be affected by such activities;
    • The anticipated impact of the activity upon the species or stocks;
    • The anticipated impact of the activity on the availability of the species or stocks for subsistence uses;
  • The anticipated impact of the activity upon the habitat of the marine mammal populations and the likelihood of restoration of the affected habitat;
  • The anticipated impact of the loss or modification of the habitat on the marine mammal population involved;
  • The availability and feasibility (economic and technological) of equipment, methods, and manner of conducting such activity or other means of effecting the least practicable adverse impact upon the affected species or stocks, their habitat, and, where relevant, on their availability for subsistence uses, paying particular attention to rookeries, mating grounds, and areas of similar significance;
  • A suggested means of accomplishing the necessary monitoring and reporting which will result in increased knowledge of the species through an analysis of the level of taking or impacts and suggested means of minimizing burdens by coordinating such reporting requirements with other schemes already applicable to persons conducting such activity; and
  • A suggested means of learning of, encouraging, and coordinating research opportunities, plans and activities relating to reducing such incidental taking from such specified activities, and evaluating its effects.

After the FWS receives the application, it reviews the application materials for completeness. If additional information is necessary, the NMFS may contact the applicant to request the needed information.

12-FD-h.4 to 12-FD-h.6 – Complete NEPA Process

The National Environmental Policy Act (NEPA) requires federal agencies to consider the potential environmental consequences of their proposed actions and any reasonable alternatives before undertaking a major federal action. The issuance of a permit by a federal agency is considered a major federal action. Consequently, a NEPA analysis must be performed before an LOA can be issued. If the applicant is a federal agency, they will usually be required to perform their own NEPA analysis for the proposed activity. If a NEPA analysis has already been performed, it must be submitted to the FWS in order to determine its applicability to the LOA. If applicable, the FWS may adopt it.

12-FD-h.7 to 12-FD-h.8 – Will an ESA-Listed Species be Taken?; Initiate Section 7 Consultation with ESA Division

Section 101(a)(5) of the MMPA allows the FWS to authorize incidental takes of marine mammals on the Endangered Species Act (ESA) endangered species list. Takings of ESA-listed marine mammals must be authorized under both the ESA and MMPA. Consequently, the FWS and federal applicants must initiate a Section 7 consultation with the ESA division of the FWS when an ESA-listed species is involved. For more information on the ESA process, see ESA Section 7 Consultation Process:

12-FD-h.9 to 12-FD-h.11 – Make Preliminary Determinations; Proposed Rule

After receiving the application, the FWS makes preliminary determinations regarding the proposed activity’s impact on the species and the availability of the species stock for subsistence uses. If the FWS determines that the proposed activity will have a “negligible impact” on the species and that it will not cause an “unmitigatable adverse impact” on the availability of the stock for subsistence uses, a Proposed Rule is drafted. The FWS must issue its findings and the Proposed Rule for comment and publish a Notice of Availability in the Federal Register. See Section 101(a)(5)(i)(I) of the MMPA; 50 CFR 18.27(d)(2).

12-FD-h.12 to 12-FD-h.13 – Make Determinations Necessary for Issuance of the ITRS and the LOA; Final Rule

After the close of the public comment period, the FWS must finalize the determinations necessary for the issuance of the ITRs and the LOA. The final determinations are based on:

  • A review and analysis of the public comments;
  • The final findings of the ESA consultation and the associated biological opinion;
  • The final findings of the NEPA process;
  • The developer’s ability to implement necessary mitigation to comply with the MMPA, the ESA and NEPA;
  • The consistency of the Proposed Rule with requirements of applicable statutes.

The final determinations may require modification of the regulations or require additional mitigation measures. See 50 CFR 18.27(d)(3). The ITRs become effective 30 days after the Final Rule is published.

Once the final determinations have been made, the FWS publishes the Final Rule in the Federal Register, which includes applicable authority, a preamble, and responses to substantive comments. In addition, 50 CFR 18.27(e) requires the regulations to set forth:

  • Permissible methods of taking;
  • Means of effecting the least practicable adverse impact on the species and its habitat and on the availability of the species for subsistence uses; and
  • Requirements for monitoring and reporting.

12-FD-h.14 to 12-FD-h.15 – Submit Request for LOA, as Outlined in the ITRs

50 CFR 18.27(f) requires the FWS to issue an LOA before the developer can conduct activities pursuant to the regulations established by the Final Rule. Procedures for submitting a request for an LOA are outlined in the ITRs. Once the request for the LOA is received, the FWS evaluates the request based on whether the level of taking is consistent with the findings made for the total taking allowable under the Final Rule.

12-FD-h.16 to 12-FD-h.17 – Issue Denial

If the level of taking requested by the developer is not consistent with the Final Rule and the regulations contained therein, the FWS will deny the LOA request. The developer may make a request for reconsideration and appeal a denial of that request in accordance with 50 CFR 13.29.

12-FD-h.18 to 12-FD-h.19 – Letter of Authorization

If the level of taking requested by the developer is consistent with the Final Rule and the regulations contained therein, the FWS will issue the LOA. The LOA must specify the period of validity and any additional terms and conditions appropriate for the specific request. See 50 CFR 18.27(f)(4). Notice of issuance of all LOAs must be published in the Federal Register within 30 days of issuance. See 50 CFR 18.27(f)(3).
