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:
- 1,496 nm2 (5,131 km2) of sea space (BOMBEX Hotbox, where high explosives occur, and UNDET Area E3 where underwater detonations occur); and
- 11,714 nm2 (40,178 km2) 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° 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° 9′33″ W and 27° 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 (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.Start Printed 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.
|Operation||Platform||System/ Ordnance||Number of Events||Training Area||Potential Time of Day|
|Bombing Exercise (BOMBEX) (Air-to-Surface, At-Sea)||F/A-18||MK-83 [1,000-lb High Explosive (HE) bomb] 415.8 lbs NEW||1 event (4 bombs)||BOMBEX Hotbox||Daytime only|
|Gunnery Exercise (GUNEX) (Surface-to-Surface) - Boat||Vessels such as combat rubber raiding craft, rigid hull inflatable boats, and patrol craft||M3A2 concussion grenades (8-oz HE grenade) 0.5 lbs NEW||4 events (20 grenades)||UNDET Area E3||Day or night|
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 nm2 (40,178 km2). 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/nm2 (0.0386 km2)).
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.
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.Start Signature
