Apr 18, 2012
The final rules are expected to yield a nearly 95 percent reduction in emissions of volatile organic compounds (VOCs) from more than 11,000 new hydraulically fractured gas wells each year. This significant reduction would be accomplished primarily through capturing natural gas that currently escapes into the air, and making that gas available for sale. The rules also will reduce air toxics, which are known or suspected of causing cancer and other serious health effects, and emissions of methane, a potent greenhouse gas.
EPA Proposes First Carbon Pollution Standard for New Power Plants

Greenhouse Gas Reporting
Nov 22, 2010
EPA finalized a rule on the greenhouse gas (GHG) reporting requirements for facilities that carry out geologic sequestration. Sequestration allows large emitters of carbon dioxide to significantly reduce the GHGs they emit. Information gathered under the rule will enable EPA to track the amount of carbon dioxide sequestered by these facilities.
EPA to Expand Chemicals Testing for Endocrine Disruption
Nov 16, 2010
EPA has identified a list of 134 chemicals that will be screened for their potential to disrupt the endocrine system.

Deepwater Horizon Oil Spill
Apr 20, 2010
The BP-operated Deepwater Horizon oil rig in the Gulf of Mexico explodes, killing eleven workers. The resulting release is the largest oil spill in American history. President Obama, EPA Administrator Jackson and hundreds of other federal, state and local officials step up to address the challenge. 
Stronger Smog Standard
Jan 6, 2010
EPA proposes the strictest health standards to date for smog. Smog, also known as ground-level ozone, is linked to a number of serious health problems, ranging from aggravation of asthma to increased risk of premature death in people with heart or lung disease. Ozone can even harm healthy people who work and play outdoors.
Greenhouse Gases Endangerment Finding

Dec 22, 2008
A containment pond rupture at the Tennessee Valley Authority's Kingston Fossil Plant in Roane County, Tennessee releases 1.1 billion gallons of coal fly ash slurry on land and into waterways. The incident has since led the EPA to begin to review coal ash sites throughout the country. 
Stronger Lead Standards
Oct 16, 2008
The first new lead standards in 30 years require a tenfold decrease in lead levels. The new standard became .15 micrograms of lead per cubic meter of air and was based on new research and Clean Air Scientific Advisory Council recommendations.

Largest Clean Air Act Settlement with Utility
Apr 21, 2003
Virginia Electric Power Co. (VEPCo) agrees to spend $1.2 billion to reduce its annual 237, 000 tons of emissions. The company's 10 electrical power plants release sulfor dioxide and nitrogen oxides, which are acid rain ingredients. VEPCo also spent five million dolllars on projects in states affected by the coal-fired plants' pollution. For example, the company paid for schoolbus engine retrofitting to reduce diesel exposure and solar panels on municipal buildings.

Administrator Whitman signs a global treaty on Persistent Organic Pollutants (POPs). The agreement between over 90 nations was important for the U.S. because the toxic chemicals can harm Americans even when they're used abroad. That's because they stay in the environment for long periods of time and accumulate as they move from soil to plants to the food we eat.
Administrator Christine Todd Whitman
Jan 30, 2001 to Jun 26, 2003
Christine Todd Whitman becomes EPA Administrator under President George W. Bush. As Administrator she introduced the Clear Skies Initiative; established a watershed-based approach to protecting our nation's lakes, streams, and rivers; and saw the passage of landmark brownfields legislation that is bringing economic and environmental vitality back to neighborhoods marred by abandoned industrial sites.

Dec 19, 1995
EPA requires municipal waste combustors -- incinerators that burn household and commercial waste -- to reduce toxic emissions by 90 percent from 1990 levels. About 90 percent of municipal waste combustors are waste-to-energy plants which generate electricity or steam from burning garbage for commercial and residential use.
First Refinery Regulation
Jul 28, 1995
The EPA announces a rule to reduce air pollution at 192 petroleum refineries and all future sites. The 53,000-ton emissions cut benefitted 4.5 million Americans living near the refineries.

Jun 30, 1994
EPA launches its Brownfields Program to clean up abandoned, contaminated sites and return them to productive community use.

Cryptosporidium Outbreak in Milwaukee
Mar 23, 1993
Cryptosporidium, a parasidic disease spread by contaminated water, sickens 400,000 people and kills more than 100 in Milwaukee, Wisconsin. Now, EPA regulates Cryptosporidium in drinking water, through the Interim Enhanced Surface Water Treatment Rule.
Acid Rain for Sale
Mar 5, 1993
EPA rules that the right to emit sulfur dioxide, an acid rain ingredient, will become a commodity in 2000. The goal was to create an incentive for companies to reduce pollution, because they could resell their alloted emissions rights if they polluted less than the legal limit. This was the first time emission rights could be traded.
Administrator Carol M. Browner
Jan 21, 1993 to Jan 18, 2001
Carol M. Browner begins the longest term of any EPA Administrator, eight years, under President Bill Clinton. Under Browner's leadership, the EPA created the first-ever comprehensive restoration plan for the Florida Everglades and implemented Clinton's Clean Water Action Plan. Browner also set new standards for pesticides used in food production and supported the public's right to a transparent government.

Eco-Terrorism Against Kuwait
Mar 10, 1991
After Iraqi forces torch and destroy over 500 oil wells, the EPA leads a team into Kuwait to see if the air is toxic enough to kill. Luckily it wasn't, but the damage was still devastating.
