The EPA recently finalized a plan to address serious air pollution that is dramatically reducing visibility at the Big Bend and Guadalupe Mountains National Parks in Texas and the Wichita Mountains National Wildlife Refuge in Oklahoma.
EPA Administrator Gina McCarthy noted that William D. Ruckelshaus is the architect of many key EPA programs: banning DDT; setting the first air quality standards to protect public health under the Clean Air Act; establishing standards for cleaner cars and lead-free gasoline; and later launching the Superfund program and setting the agency on a course to address the challenge of acid rain.
They are 3,000-horsepower engines that meet EPA's Tier-3 emissions standards for locomotives. NS will have 15 of them working at its five major Chicago railyards by the end this year and said the locomotives are expected to prevent the release of 7.58 tons of particulate matter and 196 tons of nitrogen oxides pollutants annually.
The Financial Times has obtained documents revealing Europe’s top environmental regulator raised concerns years ago.
With a $399,000 grant from the EPA, the Colorado Department of Public Health and Environment will be able to conduct air toxics measurements in the Globeville, Elyria, and Swansea neighborhoods that are located just adjacent to the I-70/I-25 freeway interchange.
The standards will tighten the National Ambient Air Quality Standards for ground-level ozone to 70 parts per billion, down from from 75 ppb, in order to protect public health. Depending on the severity of their ozone problem, areas would have until between 2020 and 2037 to meet the standards.
The Sept. 25 forecast was for "Very Unhealthy" air quality, possibly "Hazardous," so the ministry closed kindergartens and primary, secondary, and special education schools for the day.
"Discrepancies relate to vehicles with Type EA 189 engines, involving some eleven million vehicles worldwide. A noticeable deviation between bench test results and actual road use was established solely for this type of engine. Volkswagen is working intensely to eliminate these deviations through technical measures," the company's statement says.
"Our goal now is to ensure that the affected cars are brought into compliance, to dig more deeply into the extent and implications of Volkswagen's efforts to cheat on clean air rules, and to take appropriate further action," CARB Executive Officer Richard Corey said.
Those living within the nine square miles surrounding an airport are exposed to higher levels of airborne toxins.
The settlement resolves federal claims that the company violated the act by unlawfully modifying units at five coal-fired power plants in North Carolina.
"The key areas of focus for ISO 14064-1 will be accounting for indirect greenhouse gas emissions and the linkage between that and renewable energy, which is a very challenging area," said Tom Baumann, chair of the ISO TC 207/SC7 committee that undertook the revision.
With the EPA proposing to lower the primary ozone standard from 75 ppb to 70 or 65 ppb, researchers at the University of Colorado Boulder and the NOAA have created a commentary on how the new standard could make research more difficult for air quality managers at both local and state levels.
Exposure to the pollution caused by such things as car exhaust and coal-fired power plants may be associated with an increased risk of autism spectrum disorder, a University of Pittsburgh study has found.
Despite progress, Southern California's air remains home to some of the worst air in the United States, the American Lung Association said Tuesday in its annual State of the Air report.
A new U.S. Environmental Protection Agency formula for calculating the amount of pollutants released by flares at refineries and chemical plants nationwide shows that those emissions are four times higher than previously thought.
The use of clean fuels and updated pollution control measures in school buses that 25 million children ride every day could result in 14 million fewer absences from school a year, based on a study by the University of Michigan and the University of Washington.
China has revived a controversial concept to monitor pollution, a decade after its first attempt at calculating its "green GDP" suffered a swift death.
Doctors call for life-saving protections at federal EPA hearing in Arlington.
Two hundred fifty-nine state legislators from across the nation submitted a letter to the Environmental Protection Agency supporting the EPA’s efforts to reduce carbon dioxide pollution and urging the EPA to increase its renewable energy and efficiency goals.
