Climate: EPA eyes limits on airline carbon pollution

U.S. airlines have long lobbied against any measures aimed at cutting greenhouse gas emissions from aircraft, but they probably won't be able to dodge new EPA pollution regulations developed under the authority of the Clean Air Act.

Agency targets spring 2016 to make initial findings

By Bob Berwyn

FRISCO — U.S. airlines may soon be required to at least start thinking about cutting their carbon footprint.

Aviation accounts for about 11 percent of carbon dioxide emissions from the U.S. transportation sector and is one of the fastest-growing sources of carbon pollution, rising between 3 percent to 5 percent a year. Carbon emissions from global aviation will quadruple by mid-century without action. Continue reading

EPA to study pesticide impacts to endangered species

f

How do pesticides affect wildlife? We’ll know more after a court-ordered environmental study.

Legal settlement requires agency to analyze effects of 5 common pesticides

Staff Report

FRISCO — Under legal pressure from conservation advocates, the EPA last week agreed to take a hard look at how five commonly used pesticides affect endangered animals across the U.S.

One of the pesticides is carbaryl, commonly used in massive quantities in Colorado to try and protect trees from bark beetles. The other pesticides to be reviewed are chlorpyrifos, diazinon, malathion and methomyl. All have all been found to be toxic to wildlife and may pose a health risk to humans. Continue reading

Staff Report

FRISCO — With recent increases in levels of toxic metals in Peru Creek, the ongoing remediation work at the abandoned Pennsylvania Mine, near Keystone, Colo., takes on an even greater importance in the context of water quality in the Blue River Basin and the Upper Colorado.

The mine, which produced huge amounts of silver 100 years ago, has been pinpointed as one of the main sources of acid mine drainage. Water seeping through the rocky ground trickles into the old mine workings, picks up contaminants along the way, then percolates back into Peru Creek near the head of the beautiful alpine valley.

During the last couple of summers, scientists and engineers have been working to reduce the pollution, and this coming week (July 30) there will be a public field trip to the site, led by Jeff Graves of the Colorado Division of Reclamation Mining and Safety, as well as other members of the Snake River Task Force.

Staff Report

FRISCO — A proposed mine in coastal Alaskan waters would spread across an area larger than Manhattan and jeopardize the health and sustainability of one of the world’s great salmon fisheries, the EPA said this week, releasing a draft version of its plan for protecting aquatic resources in Bristol Bay from a vast open pit mine.

According to the EPA, the proposed mine in its present form would have unacceptable impacts on Bristol Bay natural resources. As a result, the agency’s draft lays out common sense rules and guidelines that would ensure the integrity of those resources by prohibiting the discharge of any mining materials into critically important waters of the U.S. Continue reading

Colorado: Not much love for proposed new water diversions

By Bob Berwyn

FRISCO — For all the detailed information in the 16,000-page study for Denver Water’s proposed new water diversions from the Western Slope, there are still more questions than answers, according to formal comment letters filed in the past few weeks.

As currently configured, the proposal to shunt more water from Colorado River headwaters streams to the Front Range could worsen water water quality in many streams that are already feeling the pain of low flows, EPA water experts wrote in a June 9 letter. Continue reading

Energy: Anadarko to pay $5.15 billion fine for fraud

Trail of toxic waste catches up with corporate polluters.

Largest ever toxic waste settlement will help communities around the country

By Summit Voice

FRISCO — A trail of toxic waste sites around the country finally caught up with Kerr-McGee and various subsidiaries of Anadarko Petroleum Corporation last week.

Under a settlement agreement with the EPA and the U.S. Department of Justice,  Anadarko will pay $5.15 billion to a litigation trust. According to the EPA, the settlement is the largest recovery for the cleanup of environmental contamination in history.

The award came after a bankruptcy court in New York found that Kerr-McGee and the Anadarko subsidiaries played a shell game, selling off assets to try and evade their liabilities for cleanups at toxic sites around the country. Continue reading
