Clean Air Act: Emerging Mercury Control Technologies Have Shown Promising Results, but Data on Long-Term Performance Are Limited
GAO-05-612: Published: May 31, 2005. Publicly Released: Jun 23, 2005.
In March 2005, the Environmental Protection Agency (EPA) issued a rule that will limit emissions of mercury--a toxic element that causes neurological problems--from coal-fired power plants, the nation's largest industrial source of mercury emissions. Under the rule, mercury emissions are to be reduced from a baseline of 48 tons per year to 38 tons in 2010 and to 15 tons in 2018. In the rule, EPA s...
Clean Air Act: Observations on EPA's Cost-Benefit Analysis of Its Mercury Control Options
GAO-05-252: Published: Feb 28, 2005. Publicly Released: Mar 7, 2005.
Mercury is a toxic element that can cause neurological disorders in children. In January 2004, the Environmental Protection Agency (EPA) proposed two options for limiting mercury from power plants, and plans to finalize a rule in March 2005. The first would require each plant to meet emissions standards reflecting the application of control technology (the technology-based option), while the secon...
Environmental Protection: EPA Should Strengthen Its Efforts to Measure and Encourage Pollution Prevention
GAO-01-283: Published: Feb 21, 2001. Publicly Released: Mar 26, 2001.
Limited quantitative data exists on the extent to which American industry has sought to use pollution prevention methods to reduce pollutants discharged from its facilities. This shortcoming has inhibited the Environmental Protection Agency's (EPA) efforts to monitor and encourage companies' use of pollution prevention measures. Whether to undertake pollution prevention is typically a business dec...
Hazardous Waste: Effect of Proposed Rule's Extra Cleanup Requirements Is Uncertain
GAO-01-57: Published: Oct 20, 2000. Publicly Released: Nov 20, 2000.
The Environmental Protection Agency (EPA) proposed several amendments to its 1993 Corrective Action Management Unit (CAMU) rule. The CAMU rule currently allows agencies to set aside part of their hazardous waste site to deposit wastes without triggering the requirements of the Recovery Conservation and Recovery Act (RCRA). EPA's action is in response to a lawsuit alleging that the CAMU rule would...
Environmental Protection Agency: Use of Precautionary Assumptions in Health Risk Assessments and Benefits Estimates
GAO-01-55: Published: Oct 16, 2000. Publicly Released: Oct 16, 2000.
Some of the Environmental Protection Agency's (EPA) regulations set standards that limit environmental contaminants to levels that are determined, in large part, on the basis of the health risks they pose. When EPA assesses the health risks of contaminants, however, the agency is faced with uncertainties and gaps in scientific knowledge and data. This report summarizes GAO's findings on whether EP...
Hazardous Waste: EPA Has Removed Some Barriers to Cleanups
