pollution

The Environmental Protection Agency was investigating an old mine near Silverton, Colo., earlier this month, when it accidentally released 3 million gallons of toxic waste water into the Animas River.

Initially the agency downplayed the incident and provided little information. So Navajo President Russell Begaye traveled to the source of the toxic spill and posted a video of it on Facebook.

In the video, he stands in front of the still-leaking mine.

In an event that has led to health warnings and turned a river orange, the Environmental Protection Agency says one of its safety teams accidentally released contaminated water from a mine into the Animas River in southwest Colorado.

The spill, which sent heavy metals, arsenic and other contaminants into a waterway that flows into the San Juan National Forest, occurred Wednesday. The EPA initially said 1 million gallons of wastewater had been released, but that figure has risen sharply.

President Obama formally unveiled his plan to cut power plant emissions — some two years in the making — calling it the "single most important step that America has ever made in the fight against global climate change."

Monday's Supreme Court decision to reject the Environmental Protection Agency's air pollution rules won't have any immediate effect on Northwest power plants, and its long-term effects are still unclear.

The court ruled the EPA should have considered the cost of mercury and toxic air pollution limits earlier in the regulatory process. With that, the judges sent the rule back to the U.S. Court of Appeals for the District of Columbia Circuit for review.

Several dairies accused of polluting the groundwater in Washington’s Yakima Valley will now start handling their waste more carefully. That’s because a federal judge has approved an order between environmental groups and dairies. Environmental groups had sued the dairies because they worried about pollution leaking into water supplies.

The Department of the Interior has unveiled new regulations on hydraulic fracturing operations that take place on federal lands, requiring companies using the drilling technique to ensure wells are safe and to disclose chemicals used in the process.

The rules change follows a more than three-year review process and will affect the 90 percent of oil and gas wells on federal lands that now use so-called fracking to extract oil and gas.

Washington regulators say the region's biggest oil-train operator should be penalized after failing to comply with reporting requirements following 14 spills of hazardous materials, including crude oil.

The state Utilities and Transportation Commission said Thursday an investigation had found that between Nov. 1 of last year and Feb. 24, BNSF Railway committed 700 violations of the state's reporting requirement for railway spills of hazardous materials. Four of those spills involved trains carrying crude oil through Washington state.

New Oregon Rules Require 10 Percent Cleaner Fuels

Jan 8, 2015

The Oregon Environmental Quality Commission voted 4-1 Wednesday to pass new rules that will reduce greenhouse gas emissions from transportation fuels by 10 percent over a decade.

The rules require companies that import fuel into Oregon to reduce the carbon intensity of their fuel mix. That will mean substituting alternative fuels such as biofuel, natural gas, propane or electricity for gasoline and diesel.

Ross Reynolds interviews Denis Hayes about the forthcoming book he co-wrote with his wife, Gail Boyer Hayes, called “Cowed: The Hidden Impact of 93 Million Cows on America’s Health, Economy, Politics, Culture, and Economy.”

The couple was on a driving tour of Great Britain when they noticed many small herds of cattle. That got Denis Hayes, an environmentalist who organized the first Earth Day and now heads the Seattle-based Bullitt Foundation, thinking about the impact of cows.

The EPA has given the state of Idaho notice that a corner of the Idaho panhandle isn't meeting stricter new air quality standards. The agency intends to change that by forcing the state to reduce what are called “fine particulates” in the air.

Steve Scher talks to energy expert Mikkal Herberg about  China's proposed crack down on air pollution.

RICHLAND, Wash. — A new climate study says pollution in Asia can influence weather over much of the world.

Researchers from Pacific Northwest National Laboratory helped develop a new type of climate model that was used to develop the study. It was published in the current issue of Proceedings of the National Academy of Sciences.

Some bad news for backcountry in the West: Some of the fish in the region’s wild alpine lakes contain unsafe levels of mercury, according to a new study by the U.S. Geological Survey.

Nitrate air pollution is higher in the Yakima Valley than many other places in Washington. The state Department of Ecology noticed the pocket of unusually high amounts of nitrate air pollution and commissioned researchers at Washington State University and Central Washington University to determine its source.

These fine particulates are so tiny that you can't see them, but if you breathe them in at high concentrations, they can cause heart and respiratory problems.

Westerly winds can carry air pollution from China across the Pacific Ocean in just a few days.

The study was published in the Proceedings of the National Academy of Sciences by researchers in the United Kingdom, China and the U.S.
