The Action Proponents must implement the following monitoring and reporting requirements when conducting the specified activities:

(a) Notification of take. If the Action Proponent reasonably believes that the specified activity identified in § 218.80 resulted in the mortality or serious injury of any marine mammals, or in any Level A harassment or Level B harassment of marine mammals not identified in this subpart, then the Action Proponent shall notify NMFS immediately or as soon as operational security considerations allow.

(b) Monitoring and reporting under the LOAs. The Action Proponents must conduct all monitoring and reporting required under the LOAs.

(c) Notification of injured, live stranded, or dead marine mammals. Action Proponent personnel must abide by the Notification and Reporting Plan, which sets out notification, reporting, and other requirements when dead, injured, or live stranded marine mammals are detected. The Notification and Reporting Plan is available at: https://www.fisheries.noaa.gov/national/marine-mammal-protection/incidental-take-authorizations-military-readiness-activities.

(d) Annual AFTT Study Area marine species monitoring report. The Navy, on behalf of the Action Proponents, must submit an annual AFTT Study Area marine species monitoring report describing the implementation and results from the previous calendar year. Data collection methods will be standardized across range complexes and the AFTT Study Area to allow for comparison in different geographic locations. The draft report must be submitted to the Director, Office of Protected Resources, NMFS, annually. NMFS will submit comments or questions on the report, if any, within 3 months of receipt. The report will be considered final after the Action Proponents have addressed NMFS' comments, or 3 months after submittal of the draft if NMFS does not provide comments on the draft report. The report must describe progress of knowledge made with respect to intermediate scientific objectives within the AFTT Study Area associated with the Integrated Comprehensive Monitoring Program. Similar study questions must be treated together so that progress on each topic can be summarized across all Navy ranges. The report need not include analyses and content that do not provide direct assessment of cumulative progress on the monitoring plan study questions.

(e) Quick look reports. In the event that the sound levels analyzed in the preambles of the Marine Mammal Protection Act (MMPA) proposed rule (90 FR 19858, May 9, 2025) and final rule (90 FR 50504, November 7, 2025) were exceeded within a given reporting year, the Action Proponents must submit a preliminary report(s) detailing the exceedance within 21 days after the anniversary date of issuance of the LOAs.

(f) Annual AFTT training and testing reports. Regardless of whether analyzed sound levels were exceeded, the Navy must submit a detailed report (AFTT Annual Training Exercise Report and Testing Activity Report) and the Coast Guard must submit a detailed report (AFTT Annual Training Exercise Report) to the Director, Office of Protected Resources, NMFS, annually. NMFS will submit comments or questions on the reports, if any, within 1 month of receipt. The reports will be considered final after the Action Proponents have addressed NMFS' comments, or 1 month after submittal of the drafts if NMFS does not provide comments on the draft reports. The annual reports must contain a summary of all sound sources used (total hours or quantity (per the LOAs) of each bin of sonar or other non-impulsive source; total annual number of each type of explosive exercises; and total annual expended/detonated rounds (missiles, bombs, sonobuoys, etc.) for each explosive bin). The annual reports must also contain cumulative sonar and explosive use quantity from previous years' reports through the current year. Additionally, if there were any changes to the sound source amount analyzed in the reporting year, or cumulatively, the reports would include a discussion of why the change was made and include analysis to support how the change did or did not affect the analysis in the 2025 AFTT Supplemental Environmental Impact Statement/Overseas Environmental Impact Statement (https://www.nepa.navy.mil/aftteis/) and the analysis in the MMPA final rule (90 FR 50504, November 7, 2025). The annual reports must also include the details regarding specific requirements associated with the mitigation areas listed in paragraph (f)(4) of this section. The analysis in the detailed report must be based on the accumulation of data from the current year's report and data collected from previous annual reports. The final annual/close-out reports at the conclusion of the authorization period (year 7) will also serve as the comprehensive close-out reports and provide the annual totals for each sound source bin with a comparison to the annual amount analyzed and the 7-year total for each sound source bin with a comparison to the 7-year amount analyzed.
