Activists to challenge EPA approval of new herbicide

Corn husks, stalks and leaves could help provide material for a sustainable source of biofuel.

Activists challenge EPA approval of new herbicides.

Chemical-agricultural death spiral continues …

Staff Report

FRISCO — A coalition of farmers and environmental groups claim the EPA didn’t adequately analyze the human health and environmental impacts of a powerful new herbicide before authorizing for use on genetically engineered corn and soybean crops.

Activists said they will sue the agency over the approval, explaining that use of Dow’s Enlist Duo, a blend of glyphosate and 2,4-D, will only foster more weed resistance.

“The voices of independent family farmers are being drowned out by the revolving door of corporate and government agency heads,” said Mississippi farmer Ben Burkett. “It’s time for our government to pay attention to the farmer concerns about the negative impacts of herbicide-resistant GMO on our food supply,” said Burkett, president of the National Family Farm Coalition.

FRISCO — For decades, the abandoned Pennsylvania Mine has been oozing heavy metals — zinc, manganese, cadmium, lead and and arsenic — into the waters of Peru Creek, a small tributary of the Snake River near Keystone, Colorado. The site has been the focus of intensive study during the past 15 years with the goal of improving water quality downstream.

Last week, engineers and environmental experts took a big step toward trying to staunch that flow by blocking one of the mine tunnels. If all goes well, the new bulkhead could reduce the direct discharge from the mine by about two-thirds, said Jeff Graves, a remediation expert with the Colorado Division of Reclamation Mining and Safety.

Graves explained that the new plug should force the water back into its natural underground pathways, trickling and percolating down through layers of rock and earth, and not as prone to the oxidation that’s key in the formation of acid mine drainage. Essentially, the work will restore the groundwater flow to more natural, pre-mining conditions, he said. Continue reading

Climate: Putting lipstick on the methane pig?

Methane emissions: up, up … up.

EPA report shows the greenhouse gas dragon is far from tamed

Staff Report

FRISCO — The EPA may be putting lipstick on the methane pig by claiming that methane emissions dropped during the past year, according to watchdog groups who say the numbers put forth by the federal agency are misleading.

Overall, the EPA reported Sept. 30 that greenhouse gas emissions from large industrial facilities climbed by 20 million metric tons in 2013, up 0.6 percent from the previous year. Continue reading

Environment: Judge upholds EPA’s review of proposed Pebble Mine, near Bristol Bay, Alaska

The EPA will be allowed to do a thorough evaluation of the impacts of a proposed copper mine in Alaska’s Bristol Bay, a federal judge has ruled.

By Bob Berwyn

FRISCO — A federal judge Friday ruled that the EPA can proceed with an environmental review of a proposed copper mine in Alaska’ pristine Bristol Bay.

U.S. District Court Judge H. Russel Holland rejected arguments that the EPA exceeded its authority by starting the review process in the absence of a specific permit application, and that the review violates the Alaska Statehood Act.

At issue is the proposed Pebble Mine, which would, according to environmental groups, become the largest copper mine in the world, potentially tainting huge areas of productive salmon habitat with dredged material and other pollutants. Continue reading

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.

U.S. airlines have long lobbied against any measures aimed at cutting greenhouse gas emissions from aircraft, but they 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

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

EPA tackling major violations around the country

Staff Report

FRISCO — A Colorado construction company has been fined $310,000 after multiple failures to comply with an EPA stormwater permit. The civil penalty is outlined in a settlement agreement sanctioned by the U.S. District Court for Colorado.

Under the settlement, Hunt Building has agreed to resolve alleged Clean Water Act violations at two military housing construction sites at the United States Air Force Academy in Colorado Springs, Colo. The violations were discovered during EPA inspections at the site. Continue reading
