The purpose of this LOA Request is to support the consultation process with the National Marine Fisheries Service (NMFS) under the Marine Mammal Protection Act for the proposed EGTTR operations. The proposed operations addressed in this LOA Request represent the Proposed Action that is being analyzed in the Eglin Gulf Test and Training Range (EGTTR) Range Environmental Assessment, currently under preparation. Current EGTTR operations are authorized under the LOA issued to Eglin AFB for the previous 5-year mission period from 2018 to 2023.  \nUnder the Proposed Action, the EGTTR would continue to be used during the next mission period based on the maritime testing and training requirements of the various military units that use the EGTTR. The next mission period would span 7 years, from 2023 to 2030. Most operations during this period would be a continuation of the same operations conducted by the same military units during the previous mission period. Most missions would continue to be air-to-surface operations that involve firing live or inert munitions, including missiles, bombs, and gun ammunition, from aircraft at targets on the water surface. The types of targets used vary by mission and primarily include stationary, remotely controlled, and towed boats, inflatable targets, and marker flares. Live munitions used in the EGTTR are set to detonate either in the air a few feet above the water surface (airburst detonation), instantaneously upon contact with the water or target (surface detonation), or approximately 5 to 10 feet below the water surface (subsurface detonation). There would be an increase in the annual quantities of all general categories of munitions (bombs, missiles, and gun ammunition) under the Proposed Action, except for live gun ammunition, which is proposed to be used less over the next mission period. The highest net explosive weight (NEW) of the munitions under the Proposed Action would be 945 pounds, which was also the highest NEW for the previous mission period.  \nLive missions proposed for the 2023–2030 period would be conducted in the existing Live Impact Area (LIA) within the EGTTR. Certain missions may also be conducted in the proposed East LIA, which would bea new, separate area within the EGTTR where live munitions would be used. Live missions that involve only airburst or aerial target detonations would continue to be conducted in or outside the LIA in any portion of the EGTTR; such detonations have no appreciable effect on marine mammals because there is negligible transmission of pressure or acoustic energy across the air–water interface. Use of inert munitions and live air-to-surface gunnery operations would also continue to occur in or outside the LIA, with new restrictions in certain areas outside the LIA as mitigation to prevent impacts to the Rice’s whale.  \nThis LOA Request analyzes the potential impacts of the Proposed Action on the common bottlenose dolphin, Atlantic spotted dolphin, and Rice’s whale. Spatial density models developed by the National Oceanic and Atmospheric Administration (2022) were used to predict the densities of these species for the impact analyses.
