Notice; issuance of a revised incidental harassment authorization.
We, NMFS, give notice that we have revised an Incidental Harassment Authorization (Authorization) issued to Point Blue Conservation Science (Point Blue) to take marine mammals, by harassment, incidental to conducting seabird research activities on Southeast Farallon Island, Año Nuevo Island, and Point Reyes National Seashore in central California. Point Blue's current Authorization is effective until January 30, 2016, and authorizes the incidental harassment, by Level B harassment only, of approximately 9,871 California sea lions (Zalophus californianus). Current environmental conditions in the Pacific Ocean offshore California—which researchers have attributed to an impending El Nino event—have contributed to unprecedented numbers of California sea lions hauled out in areas where Point Blue conducts seabird surveys. As such, Point Blue requested a modification to their current Authorization to increase the number of authorized take for California sea lions to continue their research. Per the Marine Mammal Protection Act, we are revising the Authorization to Point Blue for the incidental harassment, by Level B harassment only, a total of 41,889 California sea lions.
The authorization is still effective January 31, 2015, through January 30, 2016.

Summary of Request
On December 23, 2014, NMFS published a Federal Register notice of a proposed Authorization to Point Blue (79 FR 76975) and subsequently published a Federal Register notice of issuance of the Authorization on February 25, 2015 (80 FR 10066), effective from January 31, 2015, through January 30, 2016. To date, we have issued six one-year Authorizations to Point Blue, along with partners Oikonos Ecosystem Knowledge and Point Reyes National Seashore, for the conduct of the same activities from 2007 to 2015 (72 FR 71121, December 14, 2007; 73 FR 77011, December 18, 2008; 75 FR 8677, February 19, 2010; 77 FR 73989, December 7, 2012; 78 FR 66686, November 6, 2013; and 80 FR 10066, February 25, 2015).
On September 22, 2015, NMFS received a request from Point Blue seeking to revise the Authorization issued on January 31, 2015 (80 FR 10066, February 25, 2015) to increase the number of authorized take of small numbers of California sea lions from approximately 9,871 to a total of 44,871 for the duration of the current Authorization which expires on January 30, 2016. Current environmental conditions in the Pacific Ocean offshore California—which researchers have attributed to an impending El Nino event—have contributed to unprecedented numbers of California sea lions hauled out in areas where Point Blue conducts seabird surveys. As such, Point Blue requested a modification to their current Authorization to increase the number of authorized take for California sea lions to continue their seabird research activities. This was the only requested change to the current Authorization.
On October 13, 2015, NMFS published a notice (80 FR 61376) requesting comments on the proposed revision. The Federal Register notice set forth only a proposed change in the numbers of take for California sea lions. There were no other changes to the current Authorization as described in the February 25, 2015, Federal Register notice of an issued Authorization (80 FR 10066): The specified activity; description of marine mammals in the area of the specified activity; potential effects on marine mammals and their habitat; mitigation and related monitoring used to implement mitigation; reporting; estimated take by incidental harassment for Pacific harbor seals (Phoca vitulina), northern elephant seals (Mirounga angustirostris), or Steller sea lions (Eumetopias jubatus); negligible impact and small numbers analyses and determinations; impact on availability of affected species or stocks for subsistence uses and the period of effectiveness remain unchanged and are herein incorporated by reference.
Description of the Specified Activity
Point Blue will continue to monitor and census seabird colonies; observe seabird nesting habitat; restore nesting burrows; and resupply a field station annually in central California (i.e., Southeast Farallon Island, West End Island, Año Nuevo Island, Point Reyes National Seashore, San Francisco Bay, and the Russian River in Sonoma County). The purpose of the seabird research is to continue a 30-year monitoring program of the region's seabird populations.
NMFS outlined the purpose of Point Blue's activities in a previous notice for the proposed authorization (79 FR 76975, December 23, 2014). Point Blue's activities and level of survey effort have not changed since the publication of the Federal Register notice announcing the issuance of the Authorization (80 FR 10066, February 25, 2015). For a more detailed description of the authorized action, we refer the reader to that notice of Authorization (80 FR 10066, February 25, 2015).
Need for Modification to the Authorization
The Authorization requires Point Blue to monitor for marine mammals in order to implement mitigation measures to effect the least practicable adverse impact on marine mammals. Monitoring activities consist of conducting and recording observations on pinnipeds within the vicinity of the research areas. The monitoring reports provide dates, location, species, and the researcher's activities. The reports will also include the behavioral state of marine mammals present, numbers of animals that moved greater than one meter, and numbers of pinnipeds that flushed into the water. Between January 31 through November 6, 2015, Point Blue recorded the following instances of Level B harassment for the following research areas: Southeast Farallon Island/West End Island (20,052); Ano Nuevo (723); and Point Reyes (30).
Point Blue reports that between January and March, 2015, California sea lion incidental take patterns were relatively normal at the South Farallon Islands/West End Island survey locations. However, during the summer Start Printed Page 80322of 2015, warm water conditions along the California coast in summer resulted in more California sea lions hauling out in areas where Point Blue conducts its seabird research activities. Point Blue reported that throughout the summer months, sea lion numbers continued to grow, with greater numbers hauled out in areas where researchers have not normally recorded sea lion attendance. For example, since August 15, 2015 at the South Farallon Islands, Point Blue reported that thousands of sea lions hauled out in unusual locations high on the islands. During this period, Point Blue has restricted their activities as much as possible to still perform their monitoring duties while trying to minimize pinniped disturbance. Thus, NMFS has modified the current Authorization to increase the number of take by Level B harassment only for California sea lions to a total of 41,889 for the duration of the current Authorization which expires on January 30, 2016.
Comments and Responses
We published a notice of receipt of the proposed revised Authorization in the Federal Register on October 13, 2015 (80 FR 61376). During the 30-day comment period, we received one comment from the Marine Mammal Commission (Commission) which recommended that we issue the revised Authorization, provided that the proposed modification includes only the increase in the number of authorized takes based on the number of sea lions that would be harassed incidental to the seabird research and resupply activities and not include takes associated with removing sea lions from critical infrastructure (including docks, landings, and piers) and access paths or human safety concerns which is included in the authorities available under sections 101(a)(4) or 109(h) of the MMPA.
NMFS agrees with the Commission's recommendation and the revised Authorization includes only those takes for California sea lions related to seabird research and resupply activities. Point Blue requested an increase of 35,000 takes based on rough preliminary observations. However, during the MMPA consultation process, Point Blue provided us with draft monitoring reports with more accurate estimates of California sea lions harassed incidental to seabird research activities from September 23, 2015 through November 6, 2015 (approximately 20,805 animals). We further analyzed those preliminary reports and projected that Point Blue could harass an additional 21,084 California sea lions for the remainder of the current authorization. Thus, the revised Authorization for a total of 41,899 takes for California sea lions accounts for an additional 32,018 takes versus the Point Blue's requested increase of 35,000 takes.
We base these estimates on the largest estimated number of California sea lions taken by day within four reporting periods between January 31, 2015 and November 6, 2015 multiplied by 84 days remaining within the current Authorization. The resulting take estimates are 20,664 California sea lions for Southeast Farallon Island (9,334 animals divided by 38 days then multiplied by 84 days); 336 California sea lions for Ano Nuevo Island (554 animals divided by 156 days then multiplied by 84 days); and 84 California sea lion for (10 animals divided by 38 days then multiplied by 84 days). Based on our final analyses, NMFS would authorize an total 41,889 takes for California sea lions which accounts for take already incurred and the potential for increased take continuing through January 2016.
The revised Authorization also directs Point Blue and its partners to conduct other activities related to preventing damage to critical infrastructure and private property and ensuring personal human safety from hauled out pinnipeds in accordance with sections 101(a)(4) or 109(h) of the MMPA.
Marine Mammal Protection Act (MMPA)—As required by the MMPA, for the original Authorization, NMFS determined that: (1) The required mitigation measures are sufficient to reduce the effects of the specified activities to the level of least practicable impact; (2) the authorized takes will have a negligible impact on the affected marine mammal species; (3) the authorized takes represent small numbers relative to the affected stock abundances; and (4) Point Blue's activities will not have an unmitigable adverse impact on taking for subsistence purposes as no relevant subsistence uses of marine mammals are implicated by this action.
Negligible Impact: For reasons stated previously in the Federal Register notices for the proposed authorization (79 FR 76975, December 23, 2014) and the issued Authorization (80 FR 10066, February 25, 2015), NMFS anticipates that impacts to hauled-out California sea lions during Point Blue's activities would be behavioral harassment of limited duration (i.e., less than one day) and limited intensity (i.e., temporary flushing at most). NMFS does not expect Point Blue's specified activities to cause long-term behavioral disturbance, permanent abandonment of the haul out area, or stampeding, and therefore injury or mortality to occur.
With the exception of a proposed increase in the number of authorized takes for California sea lions, no other substantive changes have occurred in the interim. Based on the analysis contained herein of the likely effects of the specified activity on marine mammals and their habitat, and taking into consideration the implementation of the required monitoring and mitigation measures, NMFS finds that the total marine mammal take from Point Blue's survey activities will have a negligible impact on the affected marine mammal species or stocks.
Small Numbers: For reasons stated previously in the Federal Register notices for the proposed authorization (79 FR 76975, December 23, 2014) and the issued Authorization (80 FR 10066, February 25, 2015) NMFS estimates that four species of marine mammals could be potentially affected by Level B harassment over the course of the proposed Authorization. With the exception of an increase in authorized take for California sea lions, no other substantive changes have occurred in the interim. For California sea lions, the proposed increase in take is small relative to the population size. The revised incidental harassment number represents approximately 14 percent of the U.S. stock of California sea lion.
National Environmental Policy Act (NEPA)—In compliance with the National Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq.), NMFS prepared an Environmental Assessment (EA) analyzing the potential effects to the human environment from the issuance of a proposed Authorization to Point Blue for their seabird research activities. In January 2014, NMFS issued a Finding of No Significant Impact (FONSI) on the issuance of an Authorization for Point Blue's research activities in accordance with section 6.01 of the NOAA Administrative Order 216-6 (Environmental Review Procedures for Implementing the National Environmental Policy Act, May 20, 1999). No substantive changes have occurred in the interim.
Endangered Species Act (ESA)—No marine mammal species listed under the ESA occur in the action area. Therefore, NMFS has determined that a section 7 consultation under the ESA is not required. No substantive changes have occurred in the interim.
As a result of these determinations, we have revised the Authorization Start Printed Page 80323issued to Point Blue and its designees for the take of marine mammals incidental to their seabird research activities, provided they incorporate the previously mentioned mitigation, monitoring, and reporting requirements.
