(#04104) In a letter to the Governor of the U.S. Virgin Islands, the U.S. Environmental Protection Agency (EPA) today agreed with the Territory's assessment that all areas of the U.S. Virgin Islands meet EPA's new, more stringent health-based fine particle standard. This assessment is based on levels of pollution measured from a network of monitors over the past three years. Fine particles, or PM 2.5, have been shown to cause premature mortality, aggravate asthma and other respiratory conditions and contribute to cardiovascular problems such as heart attack and arrhythmia. "This is truly good news for the people of the U.S. Virgin Islands," said Jane M. Kenny, EPA Regional Administrator. "It is important, however, that the U.S. Virgin Islands maintain the progress it has made toward cleaner air. EPA is also doing its part to reduce PM 2.5 emissions." In a Febraury 17, 2004 letter to EPA, the U.S. Virgin Islands recommended that the entire Territory be designation as "attainment" with the new PM 2.5 standards. EPA is agreeing with that recommendation. The Agency will work closely with the Virgin Islands to ensure that the standard continues to be met and that progress will be made in even further reducing fine particle levels. EPA has a comprehensive air pollution control strategy that will reduce PM 2.5 pollution throughout the entire country. The Agency has already put into effect regulations dramatically reducing pollution from gasoline-powered vehicles, diesel trucks and buses. The Agency recently finalized regulations to control pollution from nonroad diesels, such as construction and farm equipment. PM 2.5 refers to particles measuring 2.5 microns in diameter, or about 1/30th the width of a human hair. These particles can either be emitted directly as dust or soot or can form in the atmosphere. These particles have been scientifically linked to serious health effects. Their ability to be suspended in air for long periods of time and their ability to lodge in the lung makes them a public health threat. EPA first adopted new standards to regulate PM 2.5 in 1997, along with continuing to regulate particles measuring 10 microns in diameter and a new, more protective standard for ground level ozone or smog. The progress in implementing these standards was hindered by litigation. The Supreme Court upheld the standards. In 2003, all legal challenges were addressed, allowing EPA to move forward with putting the standards into action. The Territory will have at least 120 days to comment on EPA's recommendations. EPA is required to make final decisions by December 31, 2004. EPA plans to make its decision in mid November in order to meet clean air goals as soon as possible.
