Nationwide Differential Global Positioning System (NDGPS), 22554-22556 [2013-08844]

Download as PDF 22554 Federal Register / Vol. 78, No. 73 / Tuesday, April 16, 2013 / Notices improve global supply chain transparency by requiring owners of facilities producing generic drug products and active pharmaceutical ingredients and certain other sites and organizations that support the manufacture or approval of these products to electronically self-identify with FDA and update that information annually. Annual self-identification is required for two purposes. First, it is necessary to determine the universe of facilities required to pay user fees. Second, selfidentification is a central component of an effort to promote global supply chain transparency. The information provided through self-identification enables quick, accurate, and reliable surveillance of generic drugs and facilitates inspections and compliance. Persons who self-identified for FY 2013 must self-identify again for FY 2014 between May 1, 2013, and June 1, 2013. Additional information including who is required to self-identify, how the information is submitted to FDA, the penalty for failure to self-identify, and the technical specifications are available on http://www.fda.gov/ForIndustry/ UserFees/GenericDrugUserFees/ default.htm. Please note that registration and listing under section 510 of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 360) is a different process than selfidentification under GDUFA. Many persons will thus be required to submit information separately to the respective systems. Each system populates its own database to meet unique requirements and deadlines. Both, however, are built on the same platform and based on the same technical standards. Dated: April 10, 2013. Leslie Kux, Assistant Commissioner for Policy.

ACTION: Notice of document availability. AGENCY: SUMMARY: We, the Fish and Wildlife Service, announce the availability of the VerDate Mar<15>2010 17:58 Apr 15, 2013 Jkt 229001 final revised recovery plan for Lost River sucker (Deltistes luxatus) and shortnose sucker (Chasmistes brevirostris), two endangered fish species found in only a few lakes and reservoirs in the upper Klamath Basin and Lost River sub-basin in southern Oregon and northern California. The recovery plan includes recovery objectives and criteria, and specific actions necessary to achieve downlisting and delisting from the Federal List of Endangered and Threatened Wildlife and Plants. We revised this plan because a substantial amount of new information is available related to recovery of both species, making it appropriate to incorporate that new information into the recovery program. ADDRESSES: You may obtain a copy of the revised recovery plan from our Web site at http://www.fws.gov/endangered/ species/recovery-plans.html. Alternatively, you may contact the Klamath Falls Fish and Wildlife Office, U.S. Fish and Wildlife Service, 1936 California Avenue, Klamath Falls, OR 97601 (telephone 541–885–8481). FOR FURTHER INFORMATION CONTACT: Laurie Sada, Field Supervisor, at the above address or telephone number. SUPPLEMENTARY INFORMATION: Background Recovery of endangered or threatened animals and plants to the point where they are again secure, self-sustaining members of their ecosystems is a primary goal of our endangered species program and the Endangered Species Act of 1973, as amended (Act; 16 U.S.C. 1531 et seq.). Recovery means improvement of the status of listed species to the point at which listing is no longer appropriate under the criteria specified in section 4(a)(1) of the Act. The Act requires the development of recovery plans for listed species, unless such a plan would not promote the conservation of a particular species. The Lost River sucker (Deltistes luxatus) and shortnose sucker (Chasmistes brevirostris) are two species of fish that inhabit a limited number of lakes in southern Oregon and northern California. We listed these species as endangered throughout their entire range under the Act on July 18, 1988 (53 FR 27130). The first recovery plan for the species was published on March 17, 1993 (USFWS 1993, pp. 1–108). However, since a substantial amount of additional information is now available, it is appropriate to revise the plan and incorporate this new information into the recovery program. PO 00000 Frm 00046 Fmt 4703 Sfmt 4703 Section 4(f) of the Act requires us to provide an opportunity for public review and comment prior to finalization of recovery plans, including revisions to such plans. We made the draft of this revised recovery plan available for public comment from October 18, 2011 through December 19, 2011 (76 FR 64372). We considered all information we received during the public comment period and revised the recovery plan accordingly. Species Information Lost River and shortnose suckers are very similar in ecology. They both predominantly inhabit lake environments but also periodically utilize other aquatic habitats. Both species spawn during spring over gravel bottoms in tributary streams and rivers (Buettner and Scoppettone 1990, pp. 19–20, 44–46). A relatively small, but significant, number of Lost River sucker also spawn over gravel bottoms at shoreline springs or upwellings along the margins of Upper Klamath Lake (Janney et al. 2009, pp. 8–9). Larvae spend little time in rivers or streams after hatching, drifting passively to downstream lakes within a few days (Cooperman and Markle 2003, p. 1138). Once in a lake environment, larvae move into shallow, vegetated areas along the shoreline. This vegetation provides cover from predators, protection from currents and turbulence, and food sources (Cooperman and Markle 2004, p. 365). Within one to two months, larvae become juveniles and begin to utilize non-vegetated, deeper off-shore areas (Burdick et al. 2008, p. 417). Adults occupy open water habitats throughout the year, except during spawning season, when they migrate to spawning areas. Individuals typically become reproductively mature at 4 to 7 years old, and can live for several decades. The rationales for listing Lost River sucker and shortnose sucker were similar, and many of the same threats continue, such that both species remain in danger of extinction. Habitat loss, including restricted access to spawning and rearing habitat, severely impaired water quality, and increased rates of mortality resulting from entrainment in water management structures, were cited as causes for declines in populations prior to listing (53 FR 27130; July 18, 1988). Although the rate of habitat loss has slowed in recent years, and a significant amount of habitat restoration and screening of water diversion structures has occurred, large amounts of historical sucker habitat remain unavailable or significantly altered.

navigation, in support of maritime safety requirements and to offset 
the error induced by the GPS Selective Availability \1\ function at 
that time. The Coast Guard's authority to establish, maintain, and 
operate such aids to navigation is found in 14 U.S.C. 81.
---------------------------------------------------------------------------

    \1\ Initially, high quality GPS signals were only available for 
military use. GPS signals available for civilian use were 
intentionally degraded out of concern that civilian GPS signals 
could be used to guide precision weapons. This degradation feature 
is known as Selective Availability. On May 1, 2000, President

Selective Availability feature. For more information on Selective 
Availability, visit the Coast Guard's Web site at http://www.navcen.uscg.gov/?pageName=gpsSelectiveAvailability.

    In 1997, the Department of Transportation and Related Agencies 
Appropriations Act of 1998 (Pub. L. 105-66, section 346 (111 Stat. 
1449)) authorized the implementation of the inland component of NDGPS. 
In 2006, RITA assumed the lead agency role for the inland NDGPS sites.
    On August 1, 2007, RITA published a notice in the Federal Register 
announcing that it was assessing the user needs and systems 
requirements of the inland (terrestrial) component of the NDGPS (72 FR 
42219). On April 18, 2008, based on RITA's assessment, DOT announced 
its approval of the continuation of inland NDGPS operations.
    There are currently 86 NDGPS sites throughout the United States. 
The Coast Guard funds 49 NDGPS Maritime sites. DOT funds 29 NDGPS 
Inland sites. The remaining eight NDPGS sites are under the sponsorship 
of the U.S. Army Corps of Engineers (USACE), and these sites are not 
addressed in this notice. For more information on the NDGPS, visit the 
Coast Guard's Web site at http://www.navcen.uscg.gov/?pageName=dgpsMain. Additional information on the NDGPS is available in 
the 2012 Federal Radionavigation Plan, published by the Department of 
Defense, DHS, and DOT. A copy of the 2012 Federal Radionavigation Plan 
is available for viewing in the public docket for this notice.
    DHS, through the Coast Guard, and DOT, through RITA, are analyzing 
the future requirements for the NDGPS to support investment decisions 
beyond fiscal year 2016. Future investment decisions may include: 
maintaining NDGPS as currently configured; decommissioning the entire 
NDGPS as currently configured; decommissioning a portion of the NDGPS 
and retaining select sites; or developing alternate uses for the NDGPS 
infrastructure. Contributing factors to these decisions are: (1) Coast 
Guard changes in policy to allow aids to navigation (ATON) to be 
positioned with a GPS receiver using Receiver Autonomous Integrity 
Monitoring (RAIM); (2) increased use of Wide Area Augmentation System 
(WAAS) in commercial maritime applications; (3) limited availability of 
consumer-grade NDGPS receivers; (4) no NDGPS mandatory carriage 
requirement on any vessel within U.S. territorial waters; (5) the May 
1, 2000 Presidential Directive turning off GPS Selective Availability; 
(6) continuing GPS modernization; and (7) the Federal Railroad

identify the full range and significance of these issues. We 
specifically request comments regarding the following questions:
    (1) To what extent do you use the NDGPS in its current form for 
positioning, navigation, and timing?
    (2) What would be the impact on NDGPS users if the NDGPS were to be 
discontinued?
    (3) If NDGPS were to be discontinued, what alternatives can be used 
to meet users' positioning, navigation, and timing requirements?
    (4) What potential alternative uses exist for the existing NDGPS 
infrastructure?
    After considering all comments, DHS and DOT will inform the public 
of the agreed course of action with respect to future investment in the 
NDGPS.
