SUPPLEMENTARY INFORMATION:

Background

    Sections 101(a)(5)(A) and (D) of the MMPA (16 U.S.C. 1361 et seq.) 
direct the Secretary of Commerce (Secretary) to allow, upon request, 
the incidental, but not intentional taking of marine mammals by U.S. 
citizens who engage in a specified activity (other than commercial 
fishing) if certain findings are made and regulations are issued or, if 
the taking is limited to harassment, notice of a proposed authorization 
is provided to the public for review.
    Authorization for incidental takings may be granted if NMFS finds 
that the taking will have a negligible impact on the species or 
stock(s), will not have an unmitigable adverse impact on the 
availability of the species or stock(s) for subsistence uses, and if 
the permissible methods of taking and requirements pertaining to the 
mitigation, monitoring and reporting of such taking are set forth.
    NMFS has defined ``negligible impact'' in 50 CFR 216.103 as:

    an impact resulting from the specified activity that cannot be 
reasonably expected to, and is not reasonably likely to, adversely 
affect the species or stock through effects on annual rates of 
recruitment or survival.

    With respect to military readiness activities, the MMPA defines 
arassment as:

    (i) any act that injures or has the significant potential to 
injure a marine mammal or marine mammal stock in the wild [Level A 
Harassment]; or (ii) any act that disturbs or is likely to disturb a 
marine mammal or marine mammal stock in the wild by causing 
disruption of natural behavioral patterns, including, but not 
limited to, migration, surfacing, nursing, breeding, feeding, or 
sheltering, to a point where such behavioral patterns are abandoned 
or significantly altered [Level B Harassment].

Summary of Request

    On October 2, 2008, NMFS received an application from the Navy 
requesting an authorization for the take of marine mammal species/
stocks incidental to the proposed training operations within the GOMEX 
Range Complex over the course of 5 years. These training activities are 
classified as military readiness activities. The Navy states that these 
training activities may cause various impacts to marine mammal species 
in the proposed GOMEX Range Complex Study Area. The Navy requests an 
authorization to take 9 species of cetaceans annually by Level B 
harassment, and 1 individual each of pantropical spotted dolphin and 
spinner dolphin by Level A harassment (injury). Please refer to the 
take table on page 6-17 of the LOA application for detailed information 
of the potential exposures from explosive ordnance (per year) for 
marine mammals in the GOMEX Range Complex.

Description of the Specified Activities

    The GOMEX Study Area encompasses areas at sea, undersea, and 
Special Use Airspace (SUA) in the northern Gulf of Mexico off the coast 
of the U.S. (Figures 1 and 2 of the LOA application). The portions of 
the GOMEX Study Area to be considered for the proposed action consist 
of the BOMBEX Hotbox (surface and subsurface waters) located within the 
Pensacola Operation Area (OPAREA), SUA warning areas W-151A/B/C and W-
155A/B (surface waters), and underwater detonation (UNDET) Area E3 
(surface and subsurface waters), located within the territorial waters 
off Padre Island, Texas, near Corpus Christi NAS. The portions of the 
GOMEX Study Area addressed in the Navy LOA application encompass:
    <bullet> 1,496 nm\2\ (5,131 km\2\) of sea space (BOMBEX Hotbox, 
where high explosives occur, and UNDET Area E3 where underwater 
detonations occur); and
    <bullet> 11,714 nm\2\ (40,178 km\2\) of SUA warning areas (vessel 
movements only)
    The BOMBEX Hotbox is an in-water operating and maneuvers area with 
defined air, ocean surface, and subsurface areas. The BOMBEX Hotbox is 
located in the offshore waters of the northeastern Gulf of Mexico (GOM) 
adjacent to Florida and Alabama. The northernmost boundary of the 
BOMBEX Hotbox is located 23 nm (42.6 km) from the coast of the Florida 
panhandle at latitude 30 N, the eastern boundary is approximately 200 
nm (370.4 km) from the coast of the Florida peninsula at longitude 
86[deg] 8 W.
    The SUA warning areas, W-151A/B/C and W-155A/B, are in-water 
operating and maneuver areas with defined air and ocean surface. W-
151A/B/C and W-155A/B are located in and above the offshore waters of 
the northeastern GOM adjacent to Florida and Alabama.
    The UNDET Area E3 is a defined surface and subsurface area located 
in the waters south of Corpus Christi NAS and offshore of Padre Island, 
Texas. The westernmost boundary is located 7.5 nm (13.9 km) from the 
coast of Padre Island at 97[deg] 9'33'' W and 27[deg] 24'26'' N at the 
Western most corner. It lies entirely within the territorial waters (0 
to 12 nm, or 0 to 22.2 km) of the U.S. and the majority of it lies 
within Texas state waters (0 to 9 nm, or 0 to 16.7 km). It is a very 
shallow water training area with depths ranging from 20 to 26 m.
    In the application submitted to NMFS, the Navy requests an 
authorization to take marine mammals incidental to conducting training 
operations within the GOMEX Range Complex. These training activities 
consist of surface warfare. Although vessel movement is also a 
component of the proposed GOMEX Range Complex training activities, the 
Navy concludes that it is unlikely marine mammals would be taken by 
vessel movement with the implementation of mitigation and monitoring 
measures described in the LOA application.

Surface Warfare

    Surface Warfare (SUW) supports defense of a geographical area 
(e.g., a zone or barrier) in cooperation with surface, subsurface, and 
air forces. SUW operations detect, localize, and track surface targets, 
primarily ships. Detected ships are monitored visually and with radar. 
Operations include identifying surface contacts, engaging with weapons, 
disengaging, evasion, and avoiding attack, including implementation of 
radio silence and deceptive measures. For the proposed GOMEX Range 
Complex training operations, SUW events involving the use of explosive 
ordnance include air-to-surface Bombing Exercises [BOMBEX (A-S)] and 
surface-to-surface Gunnery Exercises (GUNEX) that occur at sea.
(A) Bombing Exercise (Air-to-Surface) [BOMBEX (A-S)]
    Strike fighter aircraft, such as F/A-18s, deliver explosive bombs 
against at-sea surface targets with the goal of destroying the target. 
BOMBEX (A-S) training in the GOMEX Study Area occurs only during 
daylight hours in the BOMBEX Hotbox area.
    For the proposed BOMBEX (A-S), two aircraft will approach an at-sea 
target from an altitude of between 15,000 ft (4,572 m) to less than 
3,000 ft (914.4 m) and release a high explosive (HE) 1,000-pound (lb) 
bomb on the target. MK-83 bombs would be used. MK-83 bombs have a net 
explosive weight (NEW) of 415.8 lbs. The typical bomb release altitude 
is below 3,000 ft (914.4 m) and the target is usually a flare. The time 
in between bomb drops is approximately 3 minutes.

[[Page 19207]]

(B)Gunnery Exercise (Surface-to-Surface) [GUNEX (S-S)] Boat
    Gunnery Exercise (S-S) is a part of quarterly reservist training 
and operational activities for the Mobile Expeditionary Security Group 
(MESG) that operates out of Corpus Christi Naval Air Station (NAS). The 
MESG trains with M3A2 (0.5-lb NEW) anti-swimmer concussion grenades. 
The M3A2 grenades are small and contain high explosives in an inert 
metal or plastic shell. They detonate at about 3 m (9.8 ft) under the 
water surface within 4 to 5 seconds of being deployed. The detonation 
depth may be shallower depending upon the speed of the boat at the time 
the grenade is deployed. GUNNERY (S-S) training in the GOMEX Study Area 
may occur during day or evening hours in the UNDET Area E3.
    Table 1 below summarizes the level of Surface Warfare training 
activities planned in the GOMEX Range Complex for the proposed action.

Vessel Movement

    Vessel movements are associated with most training and operational 
activities in the GOMEX Study Area. Currently, the number of Navy 
vessels operating in the GOMEX Study Area varies based on training 
schedules and can range from 0 to about 10 vessels at any given time. 
Vessel sizes range from small boats (<35 ft, or 10.7 m) for a harbor 
security boat to 1,092 ft (332.8 m) for a CVN (carrier vessel nuclear) 
and speeds generally range from 10 to 14 knots, but may be considerably 
faster, for example an aircraft carrier aking wind while launching and 
recovering aircraft, and for small boat operations. Operations 
involving vessel movements occur intermittently and are variable in 
duration, ranging from a few hours up to 2 weeks. These operations are 
widely dispersed throughout the GOMEX Study Area, which is an area 
encompassing 11,714 nm\2\ (40,178 km\2\). Most vessel movements occur 
in the offshore OPAREAs, but vessel movements associated with MESG 
training in the UNDET Area E3 and Commander Naval Installations Command 
(CNIC) harbor security group training in the Panama City OPAREA occur 
between shore and 12 nm (22.2 km), including the nearshore zone (<3 nm, 
or 5.6 km). The Navy logs about 180 total vessel days within the GOMEX 
Study Area during a typical year. Consequently, the density of Navy 
vessels within the GOMEX Study Area at any given time is low (i.e., 
less than 0.0113 ships/nm\2\ (0.0386 km\2\)).

Proposed Monitoring and Mitigation Measures

    The Navy is developing an Integrated Comprehensive Monitoring 
Program (ICMP) for marine species to assess the effects of training 
activities on marine species and investigate population trends in 
marine species distribution and abundance in various range complexes 
and geographic locations where Navy training occurs. The primary tools 
available for monitoring include visual observations, acoustic 
monitoring, photo identification and tagging, and oceanographic and 
environmental data collection.
    A list of proposed mitigation measures and standard operating 
procedures is described in the application for the proposed training 
operations. These mitigation measures include personnel training for 
watchstanders and lookouts in marine mammal monitoring, operating 
procedures for collision avoidance and a series of measures for 
specific at-sea training events including surface-to-surface gunnery, 
etc. A detailed description of the monitoring and mitigation measures 
is provided in the application.

Information Solicited

    Interested persons may submit information, suggestions, and 
comments concerning the Navy request (see ADDRESSES). All information, 
suggestions, and comments related to the Navy GOMEX Range Complex 
request and NMFS potential development and implementation of 
regulations governing the incidental taking of marine mammals by the 
Navy training activities will be considered by NMFS in developing, if 
appropriate, the most effective regulations governing the issuance of 
letters of authorization.
