Adequacy Status of Motor Vehicle Emissions Budget in Submitted State Implementation Plan; Maricopa County PM-10 Nonattainment Area, Arizona
In this notice, EPA is notifying the public that the Agency has found that the motor vehicle emissions budget (MVEB) for particulate matter less than ten microns (PM-10) for the year 2012 in the Five Percent Plan for PM-10 for the Maricopa County Nonattainment Area (May 2012) (``Five Percent Plan'') is adequate for transportation conformity purposes. The Five Percent Plan for PM-10 in the Maricopa County Nonattainment Area was submitted to EPA on May 25, 2012 by the Arizona Department of Environmental Quality (ADEQ) as a revision to the Arizona State Implementation Plan (SIP). As a result of our adequacy findings, the Maricopa Association of Governments (MAG) and the U.S. Department of Transportation must use the MVEB for future conformity determinations.
Ocean Dumping; Sabine-Neches Waterway (SNWW) Ocean Dredged Material Disposal Site Designation
The EPA today designates four new Ocean Dredged Material Disposal Sites (ODMDS) located offshore of Texas for the disposal of dredged material from the Sabine-Neches Waterway (SNWW) Channel Improvement Project (CIP), which includes an extension of the Entrance Channel into the Gulf of Mexico, pursuant to the Marine Protection, Research and Sanctuaries Act, as amended (MPRSA). The designation of these four disposal sites does not by itself authorize the disposal of dredged material, but makes these sites available for use for dredged material from the CIP if no environmentally preferable, practicable alternative for managing that dredged material exists, and if analysis of the dredged material indicates that it is suitable for open-water disposal. This action is to designate adequate, environmentally- acceptable ocean disposal site capacity for suitable dredged material generated from new work (construction) and future maintenance dredging from the SNWW CIP.
