Federal Lands: Survey of Land Managers' Perspectives of Off-Highway Vehicle Use (GAO-09-547SP, June 2009), an E-supplement to GAO-09-509
GAO-09-547SP: Published: Jun 30, 2009. Publicly Released: Jun 30, 2009.
This is an E-supplement to GAO-09-509. This document presents the results of GAO's survey of land managers from the Department of Agriculture's Forest Service and the Department of the Interior's Bureau of Land Management (BLM) and National Park Service field units regarding their perspectives on off-highway vehicle (OHV) use on federal lands. In order to learn about these managers' perspectives o...
Clean Water Infrastructure: A Variety of Issues Need to Be Considered When Designing a Clean Water Trust Fund
GAO-09-657: Published: May 29, 2009. Publicly Released: Jun 29, 2009.
The Environmental Protection Agency (EPA) has estimated that a potential gap between future needs and current spending for wastewater infrastructure of $150 billion to $400 billion could occur over the next decade. A number of entities are involved in planning, financing, building, and operating this infrastructure. Some of these stakeholders have suggested a variety of approaches to bridge this p...
Aviation and Climate Change: Aircraft Emissions Expected to Grow, but Technological and Operational Improvements and Government Policies Can Help Control Emissions
GAO-09-554: Published: Jun 8, 2009. Publicly Released: Jun 8, 2009.
Aircraft emit greenhouse gases and other emissions, contributing to increasing concentrations of such gases in the atmosphere. Many scientists and the Intergovernmental Panel on Climate Change (IPCC)--a United Nations organization that assesses scientific, technical, and economic information on climate change--believe these gases may negatively affect the earth's climate. Given forecasts of growth...
Nuclear Waste: DOE's Environmental Management Initiatives Report Is Incomplete
GAO-09-697R: Published: Jun 2, 2009. Publicly Released: Jun 2, 2009.
The Department of Energy (DOE) spends billions of dollars annually to clean up nuclear waste at sites across the nation that produced nuclear weapons from the 1940s through the end of the Cold War. This waste can threaten public health and the environment. For example, contaminants at DOE's Hanford site in Washington have migrated through the soil into the groundwater, which generally flows toward...
Superfund: Greater EPA Enforcement and Reporting Are Needed to Enhance Cleanup at DOD Sites
GAO-09-278: Published: Mar 13, 2009. Publicly Released: Apr 16, 2009.
Prior to the 1980s and the passage of environmental legislation--particularly the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) governing environmental cleanup--Department of Defense (DOD) activities contaminated millions of acres of soil and water on and near DOD sites. The Environmental Protection Agency (EPA), which enforces CERCLA, places the most contaminated...
Climate Change: Observations on Federal Efforts to Adapt to a Changing Climate
GAO-09-534T: Published: Mar 25, 2009. Publicly Released: Mar 25, 2009.
Changes in the climate attributable to increased concentrations of greenhouse gases may have significant environmental and economic impacts in the United States. For example, climate change could threaten coastal areas with rising sea levels, alter agricultural productivity, and increase the intensity and frequency of floods and storms. Federal, state, and local agencies are tasked with a wide arr...
Environmental Protection Agency: Major Management Challenges
GAO-09-434: Published: Mar 4, 2009. Publicly Released: Mar 4, 2009.
The Environmental Protection Agency's (EPA) overarching mission is to protect human health and the environment by implementing and enforcing environmental laws intended to improve the quality of the nation's air and water and to protect its land. EPA's policies and programs affect virtually all segments of the economy, society, and government. As such, it operates in a highly complex and controver...
Chemical Regulation: Options for Enhancing the Effectiveness of the Toxic Substances Control Act
GAO-09-428T: Published: Feb 26, 2009. Publicly Released: Feb 26, 2009.
Congress passed the Toxic Substances Control Act (TSCA) in 1976, authorizing the Environmental Protection Agency (EPA) to obtain information on the risks of industrial chemicals and to control those that EPA determines pose an unreasonable risk. However, EPA does not have sufficient chemical assessment information to determine whether it should establish controls to limit public exposure to many c...
Hardrock Mining: Information on Types of State Royalties, Number of Abandoned Mines, and Financial Assurances on BLM Land
GAO-09-429T: Published: Feb 26, 2009. Publicly Released: Feb 26, 2009.
The General Mining Act of 1872 helped open the West by allowing individuals to obtain exclusive rights to mine billions of dollars worth of gold, silver, and other hardrock (locatable) minerals from federal lands without having to pay a federal royalty. However, western states charge royalties so that they share in the proceeds from various hardrock minerals extracted from their lands. For years,...
Climate Change Science: High Quality Greenhouse Gas Emissions Data are a Cornerstone of Programs to Address Climate Change
GAO-09-423T: Published: Feb 24, 2009. Publicly Released: Feb 24, 2009.
Elevated levels of greenhouse gases in the atmosphere and the resulting effects on the earth's climate could have significant impacts in the United States and internationally. Potential impacts include a change in sea levels, ecosystems, and ice cover. The United States Congress is considering proposals to limit greenhouse gas emissions using market-based mechanisms that would place a price on emi...
