- Air Quality: EPA's Proposed New Ozone and Particulate Matter Standards
- This report discusses the contentious issue of enforcing stringent national ambient air quality standards (NAAQS) for ozone and particulate matter (PM), the opponents of which decry as harmful to the economy. The report discusses actions undertaken by the EPA, President Clinton's support of the NAAQSs, and the criticisms of opponents.
- Air Quality Standards: The Decisionmaking Process
- The decisions by the Administrator of the Environmental Protection Agency (EPA) in 1997 to revise the National Ambient Air Quality Standards (NAAQS) for ozone and particulate matter refocused attention on the criteria and the process by which these decisions are made Tracing the steps of the decision pieces, this report identifies the statutory criteria established by the Congress and summarizes the administrative procedures the Agency follows in setting these standards and in reviewing them every 5 years.

- Biochar: Examination of an Emerging Concept to Mitigate Climate Change
- Biochar is a charcoal produced under high temperatures using crop residues, animal manure, or any type of organic waste material. Depending on the feedstock, biochar may look similar to potting soil or to a charred substance. The combined production and use of biochar is considered a carbon-negative process, meaning that it removes carbon from the atmosphere. This report briefly describes biochar, its potential advantages and disadvantages, legislative support, and research and development activities underway in the United States.

- Acoustic Thermometry of Ocean Climate: Marine Mammal Issues
- After global warming became a concern in the mid-1950s, researchers proposed measuring deep ocean temperatures to reveal any significant trends in core ocean warming. Acoustic thermometry can detect changes in ocean temperature by receiving low-frequency sounds transmitted across an ocean basin because the speed of sound is proportional to water temperature. Acoustic Thermometry of Ocean Climate, or ATOC, is an international program involving 11 institutions in seven nations. It is designed as a 30-month "proof-of-concept" project to provide data on possible global climate change, with funding provided by the U.S. Department of Defense. A debate has arisen over ATOC's impact on marine mammals versus the benefits of better global warming information derived from ATOC. This report dicusses the ATOC program and related concerns.
- Ocean Acidification
- With increasing concentrations of carbon dioxide (CO2) in the atmosphere, the extent of effects on the ocean and marine resources is an increasing concern. One aspect of this issue is the ongoing process whereby seawater becomes acidified (i.e., ocean acidification) as more CO2 dissolves in it, causing hydrogen ion concentration in seawater to increase. While not yet fully understood, the ecological and economic consequences of ocean acidification could be substantial. Congress is beginning to focus attention on better understanding ocean acidification and determining how this concern might be addressed.
- Ocean Acidification
- This report discusses the increasing concern, within the scientific community, that rising levels of carbon dioxide in the atmosphere could detrimentally alter marine ecosystems. The report discusses how ocean acidification happens, its possible outcomes, as well as natural and human responses that could possibly limit or reduce the rate of the process.

- Air Quality Issues and Animal Agriculture: A Primer
- This report focuses on the environmental quality of water resources as affected by animal agriculture, specifically animal waste, which can harm water quality through surface runoff, direct discharges, spills, and leaching into soil and groundwater. This report also discusses the contribution of emissions from animal feeding operations (AFO), enterprises where animals are raised in confinement, to air pollution.

- Air Quality Issues and Animal Agriculture: EPA’s Air Compliance Agreement
- This report discusses a plan announced by EPA in January 2005, called the Air Compliance Agreement, that would produce air quality monitoring data on animal agriculture emissions from a small number of farms, while at the same time protecting all participants (including farms where no monitoring takes place) through a “safe harbor” from liability under certain provisions of federal environmental laws.

- Air Quality Issues and Animal Agriculture: EPA’s Air Compliance Agreement
- From an environmental quality standpoint, much of the interest in animal agriculture has focused on impacts on water resources, because animal waste, if not properly managed, can harm water quality through surface runoff, direct discharges, spills, and leaching into soil and groundwater. A more recent issue is the contribution of emissions from animal feeding operations (AFO), enterprises where animals are raised in confinement, to air pollution. AFOs can affect air quality through emissions of gases such as ammonia and hydrogen sulfide, particulate matter, volatile organic compounds, hazardous air pollutants, and odor. These pollutants and compounds have a number of environmental and human health effects. This report reviews key issues associated with the Air Compliance Agreement.

- Clean Air Act Permitting: Status of Implementation
- The 1990 Clean Air Act amendments established an operating permit system that is affecting many new and existing sources of air emissions, as well as state and local air pollution control agencies. After delays and early missteps, the operating permit program is moving ahead. All state and local programs have received interim or full approval, and permits are being issued, although at a slower rate than anticipated. However, a number of issues exist. These include the effect of key federal regulations, not yet promulgated, on permit programs and regulated sources; adequacy of state resources; gaining full approval for those permit programs that now have interim approval; and oversight.
