EPA Seeks Comment on Proposed Decision to Register Enlist Duo Herbicide Containing the Choline Salt of 2,4-D and Glyphosate.
Monday, 05 May 2014 09:59

WASHINGTON - The EPA is making available for a 30-day public comment period a proposed regulatory decision to register Enlist Duo containing glyphosate and the choline salt of 2,4-D for use in controlling weeds in corn and soybeans genetically engineered (GE) to tolerate 2,4-D.

Weeds are becoming increasingly resistant to glyphosate-based herbicides and are posing a problem for farmers. If finalized, EPA’s action provides an additional tool to reduce the spread of glyphosate resistant weeds. To ensure that Enlist Duo successfully manages weed resistance problems, the proposal would impose requirements on the manufacturer including robust monitoring and reporting to EPA, grower education and remediation and would allow EPA to take swift action to impose additional restrictions on the manufacturer and the use of the pesticide if resistance develops.

EPA is making this action available for public comment because the choline salt of 2,4-D, which is less prone to drift and volatilization than its other forms, is not currently registered for these uses. Glyphosate, however, is already registered for several varieties of GE soybeans and corn. Since no new use pattern and no new exposures for glyphosate are being considered with this registration action, no further assessment is needed for glyphosate.

2,4-D is one of the most widely used herbicides to control weeds. 2,4-D has been registered for many years in the United States and is registered in dozens of countries, such as Canada, Mexico, Japan, 26 European Union Members, and many member countries of the Organisation for Economic Co-operation and Development (OECD).

Public comments on the EPA’s proposed regulatory decision must be submitted no later than May 30, 2014. Comments may be submitted to the EPA docket EPA-HQ-OPP-2014-0195 at

After the comment period closes, EPA will review all of the comments and reach a final decision, which the Agency expects to issue in late summer or early fall.

(Seattle - Jan. 15, 2014) The U.S. Environmental Protection Agency today released its final Bristol Bay Assessment describing potential impacts to salmon and ecological resources from proposed large-scale copper and gold mining in Bristol Bay, Alaska. The report, titled "An Assessment of Potential Mining Impacts on Salmon Ecosystems of Bristol Bay, Alaska," concludes that large-scale mining in the Bristol Bay watershed poses risks to salmon and Alaska Native cultures. Bristol Bay supports the largest sockeye salmon fishery in the world, producing nearly 50 percent of the world’s wild sockeye salmon with runs averaging 37.5 million fish each year.

Task force named to probe chemical dumping

Charlotte officials on Friday announced an interagency task force will investigate the PCBs and other toxic chemicals that were apparently dumped into the city’s sewer system.

The chemicals, which were discovered around midday Thursday at the Mallard Creek sewage-treatment plant, are not believed to have reached the creek itself. The city’s water supply was not affected.

“Anything that’s coming out of your faucet is OK,” Mayor Patrick Cannon said at a late-afternoon news conference.

The full-time task force of local, state and federal agencies will operate under the Charlotte-Mecklenburg Police Department’s arson investigations unit.

It will pursue felony charges for contaminant dumping under state and federal law. Surveillance video is already being reviewed, police Chief Rodney Monroe said.

The treatment plant shut down Thursday once workers detected a suspicious sheen on the wastewater coming into the plant. The plant started back up Friday morning.

“They had to be paying attention to see it,” Charlotte-Mecklenburg Utilities Director Barry Gullet said of his staff.

With a trickle, not a flood, West Virginia water restrictions are ending
Tuesday, 14 January 2014 09:35

(CNN) -- Sandra Fisher heard the sound of running water in her Charleston, West Virginia, home on Monday for the first time in four days after a chemical leak fouled water supplies for hundreds of thousands of people. Fisher was one of the first 5,000 customers, many of them large commercial users, who were told they could start flushing out their pipes after thousands of gallons of 4-methylcyclohexane methanol poured out of from a storage facility on the nearby Elk River on Thursday. The licorice-scented chemical, typically used to clean coal, got into Charleston's water supply, resulting in 300,000 people being told not to drink, cook or wash with water from their own taps.
