In the Summer of 2005, Congress focused on several Clean Air Act Issues before the August recess. Although the Congressional agenda stated that attention would be given to the needed amendments of the Clear Skies/Multi-Pollutant Legislation, this progress was stalled, and the committee failed to approve the bill due to a tied vote. This otherwise stagnated debate was given some attention due to the discussions over mercury regulations as they apply to power plants. The outcome of the decision concerning these regulations has stirred controversy in at least fifteen states. Perhaps the most debated issue that Congress covered concerned MTBE and Ethanol, which have been used to meet the Clean Air Act requirements that reformulated gasoline (RFG), sold in the nation’s worst ozone nonattainment areas, contain at least 2% oxygen, to improve combustion. Air quality standard deadlines and provisions, specifically in the most severe ozone nonattainment areas, were discussed by Congress. Discussions over the Clean Air Act also sparked discussions over environmental regulations concerning related issues, including the Conformity of Transportation Plans and SIPs, and Hurricane Katrina.

The collisionless limit of the transition to ion-temperature-gradient-driven plasma turbulence is considered with a dynamical-systems approach. The importance of systematic analysis for understanding the differences in the bifurcations and dynamics of linearly damped and undamped systems is emphasized. A model with ten degrees of freedom is studied as a concrete example. A four-dimensional center manifold (CM) is analyzed, and fixed points of its dynamics are identified and used to predict a ''Dimits shift'' of the threshold for turbulence due to the excitation of zonal flows. The exact value of that shift in terms of physical parameters is established for the model; the effects of higher-order truncations on the dynamics are noted. Multiple-scale analysis of the CM equations is used to discuss possible effects of modulational instability on scenarios for the transition to turbulence in both collisional and collisionless cases.

As the United States Border Patrol (USBP) discharges its mission it encounters unauthorized aliens from around the world attempting to illegally enter the United States. In fiscal year (FY) 2004, USBP agents apprehended 1.16 million people attempting to enter the country illegally between official POE; 93% of these aliens were Mexican nationals. Because the vast majority of people apprehended each year by the USBP are Mexican nationals, the agency categorizes aliens as Mexicans or Other Than Mexicans (OTM). Over the past three years, OTM apprehensions have more than tripled nationwide and have been concentrated along the South Texas border. The reasons for this dramatic increase, and its geographical concentration in Texas, are not altogether clear.

This report discusses issues for Congress regarding farm commodities. Farm commodity programs represent the heart of U.S. farm policy. The 2002 farm bill (P.L. 107-171) establishes farm income support and commodity price support programs for the 2002-2007 crop years.

Persons suspected of terrorist activity may be transferred from one State (i.e., country) for arrest, detention, and/or interrogation. Commonly, this is done through extradition, by which one State surrenders a person within its jurisdiction to a requesting State via a formal legal process, typically established by treaty. Far less often, such transfers are effectuated through a process known as “extraordinary rendition” or “irregular rendition.” These terms have often been used to refer to the extrajudicial transfer of a person from one State to another. In this report, “rendition” refers to extraordinary or irregular renditions unless otherwise specified.

The devastation caused by Hurricane Katrina is having significant negative effects on older persons with physical and mental disabilities. Persons who are socially isolated and dependent upon informal caregivers and social service programs to assist them live independently have immediate and long-term needs. The Administration on Aging (AoA) has allocated $750,000 in disaster relief funds available through the Older Americans Act to Alabama, Louisiana, and Mississippi (divided equally among the three states). Congress may consider whether additional actions are necessary to assist state and area agencies on aging in their efforts to assist the frail elderly in the wake of Hurricane Katrina.
