SUPPLEMENTARY INFORMATION:

Section 101(a)(5)(A) of the MMPA (16 U.S.C. 1361 et seq.) directs the Secretary of Commerce (who has delegated the authority to NMFS) to allow, upon request, the incidental, but not intentional, taking of small numbers of marine mammals by United States citizens who engage in a specified activity (other than commercial fishing) within a specified geographical region, if certain findings are made and regulations are issued. Under the MMPA, the term “take” means to harass, hunt, capture, or kill or to attempt to harass, hunt, capture, or kill any marine mammal.

Authorization for incidental taking, in the form of annual LOAs, may be granted by NMFS for periods up to five years if NMFS finds, after notice and opportunity for public comment, that the total taking over the five-year period will have a negligible impact on the species or stock(s) of marine mammals, and will not have an unmitigable adverse impact on the availability of the species or stock(s) for subsistence uses (where relevant). In addition, NMFS must prescribe regulations that include permissible methods of taking and other means of effecting the least practicable adverse impact on the species and its habitat (i.e., mitigation), and on the availability of the species for subsistence uses, paying particular attention to rookeries, mating rounds, and areas of similar significance. The regulations also must include requirements pertaining to the monitoring and reporting of such taking.

Regulations governing the taking of marine mammals incidental to EROS were published on June 19, 2008 (73 FR 34875), and remain in effect through July 19, 2013. For detailed information on this action, please refer to that Federal Register notice. The species that applicants may take in small numbers during EROS activities are bottlenose dolphins (Tursiops truncatus), Atlantic spotted dolphins (Stenella frontalis), pantropical spotted dolphins (Stenella attenuata), Clymene dolphins (Stenella clymene), striped dolphins (Stenella coeruleoalba), spinner dolphins (Stenella longirostris), rough-toothed dolphins (Steno bredanensis), Risso's dolphins (Grampus griseus), melon-headed whales (Peponocephala electra), short-finned pilot whales (Globicephala macrorhynchus), and sperm whales (Physeter macrocephalus). NMFS received requests for LOAs from W&T Offshore, Inc. (W&T Offshore) and W&T Energy VI, LLC (W&T Energy) for activities covered by EROS regulations.

Reporting

NMFS Galveston Laboratory's Platform Removal Observer Program (PROP) has provided reports for W&T Offshore's removal of offshore structures during 2012. W&T Energy does not have reports for any operations to date. NMFS PROP observers and non-NMFS observers reported the following during W&T Offshore's EROS operations in 2012:

Company	Structure	Dates	Marine mammals sighted (individuals)	Biological impacts observed to marine mammals
W&T Offshore	Eugene Island Area, Block 196, Platform B	March 27 to 30, 2012	Bottlenose dolphins (2)	None.
W&T Offshore	Eugene Island Area, Block 205, Platform D	April 9 to 12, 16 to 17, 23 to 25, 2012	Spotted dolphins (60)	None.

Pursuant to these regulations, NMFS has issued LOAs to W&T Offshore and W&T Energy. Issuance of the LOAs is based on a finding made in the preamble to the final rule that the total taking over the five-year period (with monitoring, mitigation, and reporting measures) will have a negligible impact on the affected species or stock(s) of marine mammals and will not have an unmitigable adverse impact on subsistence uses. NMFS will review reports to ensure that the applicants are in compliance with meeting the requirements contained in the implementing regulations and LOA, including monitoring, mitigation, and reporting requirements.
