How the EPA Works

By the 1960s, the United States was poisoning itself with pesticides. National parks and crops gave a false impression of healthy, vibrant agriculture but hid chemicals that were destroying the environment. Pesticides were killing insects and animals as well as threatening human health. In 1962, the naturalist Rachel Carson wrote a book that catalyzed the environmental movement. "Silent Spring," serialized in the New Yorker and eventually a New York Times best-seller, documented the detrimental effects of DDT, a synthetic pesticide, and other chemical compounds that caused harm to wildlife, especially to birds.

The book piqued the public's interest in environmentalism. Ecology, previously an obscure academic field, became a legitimate topic of public discussion. State and local governments enacted environmental laws, regulating polluters or banning the use of certain chemicals. But the mass of laws was confusing and often ineffectual. The United States needed a comprehensive environmental policy.

President Richard Nixon was initially reluctant to create a federal agency that set, monitored and enforced environmental laws. In 1969, he formed an environmental council and advisory committee, but met with public charges that the organizations had no effectual function. But by January 1, 1970, Nixon signed the National Environmental Policy Act (NEPA), which promised to institute a federal role in environmental protection. Nixon recognized that such federal legislation needed the attention of an exclusive agency. By the summer of 1970, he submitted Reorganization Plan Number Three to Congress, which called for a single entity to govern the United States' environmental policy [EPA].

The EPA inherited environmental charges that had been arbitrarily assigned to other governmental departments. The Department of Health, Education and Welfare no longer monitored air pollution, water hygiene and waste management; the Department of the Interior no longer had responsibility for federal water quality and pesticide research. Misplaced environmental programs were finally unified under a single agency.

With the reassignment of environmental programs and the formation of a comprehensive agency to deal with them, the U.S. was well on its way to effective environmental policy. In the next section, we'll learn about some well-known EPA programs.

The EPA initially focused on creating programs that enacted several key pieces of legislation. The first, of course, was NEPA, which called for broad environmental improvements. But the Clean Air Act of 1970, the Clean Water Act of 1972 and the Federal Environmental Pesticide Control Act of 1972 were also important early laws for the EPA to enact.

Today, the EPA manages more than a hundred programs that uphold a dozen major laws or statutes. The programs can be broadly broken down into six categories: air, pollution prevention, wastes and recycling, toxics and chemicals, water and pesticides. We'll discuss some of the EPA's most famous programs that fall into these categories.

As a governmental agency, the EPA is under constant scrutiny and has its share of critics. In the next section, we'll learn about some recent EPA controversies.

During the administration of President George W. Bush, the EPA has faced criticism regarding its commitment to enforcing environmental laws and pursuing criminal polluters. Lawsuits against the agency, congressional investigations, an overall drop in convictions and several high-profile resignations by frustrated EPA employees have critics suggesting that the EPA is no longer adequately performing its duty.

Even the Supreme Court confirms that the EPA has shirked some of its responsibilities. In April 2007, the court sided with environmentalists in Massachusetts et al. v. Environmental Protection Agency et al. In a 5-4 decision, the court ruled that the EPA was responsible for regulating new-vehicle greenhouse gas (GHG) emissions under the Clean Air Act. It was the first Supreme Court case to investigate global warming.

The case began in 1999 when several environmental groups encouraged the EPA to establish standards for new vehicles' GHG emissions. Four years after receiving the petition, the EPA replied that it had no authority to regulate such emissions and even if it did, considered it unwise to do so [source: Supreme Court]. Massachusetts joined with other states, cities and groups to sue the EPA.

The Supreme Court ruled that the EPA has the authority to regulate GHG emissions under the Clean Air Act and caused the state of Massachusetts harm by not doing so. The decision potentially gives states fighting for GHG regulations new power over the agency. California, which proposed stricter regulations in December 2005, is now suing the EPA for failing to make a ruling. The state is authorized to create its own air pollution regulations but needs EPA approval before doing so.

The EPA has also attracted attention for its sharp decline in new investigations, prosecutions and convictions -- all of which dropped by a third between 2002 and 2006. Civil lawsuits against defendants who rejected offers to settle outside of court dropped almost 70 percent [source: Washington Post]. The EPA's administration insists that numbers are down because the agency has shifted its focus to bigger cases with probable convictions.

In June 2007, former EPA Administrator Christie Todd Whitman faced a Congressional hearing over the government's environmental response to the Sept. 11 terrorist attacks. In the days following 9/11, Whitman assured the public that the air in Lower Manhattan was safe to breathe and that residents and workers could return to the area. However, the air was not safe and clinical reports from the Mount Sinai World Trade Center Screening and Monitoring Program have shown that 70 percent of 9,000 workers at the Trade Center site reported respiratory problems. Whitman denied accusations that she had manipulated EPA data under pressure from the White House [source: New York Times].
