This final rule is being issued as required by a consent decree governing the schedule for completion of this review of the air quality criteria and the secondary national ambient air quality standards (NAAQS) for oxides of nitrogen and oxides of sulfur. Based on its review, the EPA is retaining the current nitrogen dioxide (NO<INF>2</INF>) and sulfur dioxide (SO<INF>2</INF>) secondary standards to address the direct effects on vegetation of exposure to gaseous oxides of nitrogen and sulfur and, for reasons described in detail in this final preamble, is not adding new standards at this time to address effects associated with the deposition of oxides of nitrogen and sulfur on sensitive aquatic and terrestrial ecosystems. In addition, in this rule the EPA describes...

Under the authority of the Endangered Species Act of 1973, as amended (ESA), we, NMFS, issue this proposed rule to remove the eastern distinct population segment (DPS) of Steller sea lions from the List of Endangered and Threatened Wildlife. After receiving two petitions to delist this DPS, we completed a comprehensive review of the status of the eastern DPS of Steller Sea Lions. Based on the information presented in the draft Status Review, the factors for delisting in section 4 (a)(1) of the ESA, the objective recovery criteria in the 2008 Recovery Plan, and the continuing efforts to protect the species, we have determined, subject to further consideration following public comment, that this DPS has recovered and no longer meets the definition of a threatened species under the ESA: it...

We, the National Marine Fisheries Service (NMFS), issue a final rule to revise the current critical habitat for the leatherback sea turtle (Dermochelys coriacea) by designating additional areas within the Pacific Ocean. This designation includes approximately 16,910 square miles (43,798 square km) stretching along the California coast from Point Arena to Point Arguello east of the 3,000 meter depth contour; and 25,004 square miles (64,760 square km) stretching from Cape Flattery, Washington to Cape Blanco, Oregon east of the 2,000 meter depth contour. The designated areas comprise approximately 41,914 square miles (108,558 square km) of marine habitat and include waters from the ocean surface down to a maximum depth of 262 feet (80 m). Other Pacific waters within the U.S. Exclusive Econ...
