A rule proposed by the Environmental Protection Agency that aims to curb emissions from oil refineries and petrochemical manufacturers is causing tensions to flare between the agency and industry groups. The agency is reviewing a flood of public comments on the issue and is expected to finalize the rule by April 17, according to an article in Chemical & Engineering News.

The EPA has announced a proposal to reduce oil refinery pollution that, if adopted, would mark the first change to the industry's emission standards in nearly two decades. The move is part of a consent decree that resolved a lawsuit filed by nonprofit environmental attorneys with Earthjustice and the Environmental Integrity Project on behalf of people directly affected by emissions from refineries in Louisiana, Texas and California.
The U.N.'s expert panel on climate change is under pressure this week as it considers whether geoengineering should be part of the tool-kit that governments use to keep global warming in check. Drafts leaked before the conference only mentioned one of the proposed options, removing carbon dioxide from the air and storing it underground. But some countries support solar radiation management as well.
National efforts in the last decade to clear the air of dangerous particulate matter have been so successful that most urban areas have already attained the next benchmark, according to new research by Rice Univ. Atmospheric researchers at Rice studied the state implementation plans from 23 regions mandated by the EPA to reduce particulate matter (PM) smaller than 2.5 um (PM 2.5) to less than 15 micrograms per cubic meter by 2009.
For 15 years trucks have been hauling decades worth of plutonium-contaminated waste to what is supposed to be a safe and final resting place a half mile underground in the salt beds of the Permian Basin in New Mexico. But back-to-back accidents and an above-ground radiation release shuttered the government's only deep underground nuclear waste dump and raised questions about the $5-billion-a-year program for cleaning up legacy waste.
Activists taking part in U.N. climate talks say Japan's decision to drastically scale back its target for reducing greenhouse gas emissions will hurt the battle against global warming. The new target approved by the Japanese Cabinet calls for reducing emissions by 3.8% from their 2005 level by 2020.
The first trickle of fuels made from agricultural waste is finally winding its way into the nation's energy supply. But the full benefits of this fuel source remain many years away, and ethanol, which was meant to be a stop-gap until non-food sources of fuel were found, has been far more damaging to the environment than the government predicted.
How much in energy and cost savings would your state realize if it updated its commercial building energy codes? You can find out in a new online publication from the National Institute of Standards and Technology (NIST). The state-by-state reports were the product of a new building energy efficiency analysis tool developed by NIST.
A new study shows that the reduction of pollution emissions from power plants in the mid-Atlantic is making an impact on the quality of the water that ends up in the Chesapeake Bay. The study confirms a decreased amount of emissions of nitrogen oxide from coal-fired power plants.
A year ago, lawyers for BP and Gulf Coast residents and businesses took turns urging a federal judge to approve their settlement for compensating victims of the company's massive 2010 oil spill. However, the one-time allies will be at odds when an appeals court hears objections to the multibillion-dollar deal.
In waters off Long Beach, Seal Beach and Huntington Beach—some of the region's most popular surfing strands and tourist attractions—oil companies have used fracking at least 203 times at six sites in the past two decades. This discovery made from drilling records and interviews shows that offshore fracking is more widespread and frequent that state officials believed.
Linking global warming to public health, disease and extreme weather, the Obama administration pressed ahead Friday with tough requirements to limit carbon pollution from new power plants, despite protests from industry and Republicans that it would dim coal's future. The proposal, which would set the first national limits on heat-trapping pollution from future power plants, is intended to help reshape where Americans get electricity.
The U.S. Environmental Protection Agency (EPA) has launched a web-based tool, called ChemView, to significantly improve access to chemical specific regulatory information developed by EPA and data submitted under the Toxic Substances Control Act. The tool displays key health and safety data in an online format that allows comparison of chemicals by use and by health or environmental effects.
Why can’t global leaders agree on a broad, effective climate change pact? More than 20 years after they began, international negotiations based on the United Nations Framework Convention on Climate Change have resulted in only one legally binding treaty. That agreement, the Kyoto Protocol, has not been ratified by the U.S., historically the world’s largest carbon emitter.
Three weeks after giving an ambitious speech to outline his climate change proposal, President Obama begins the arduous task of executing it. His plan is a complicated mix of rulemaking and federal permitting that's tough to encapsulate in a neat sales pitch—and may be even tougher to put into action.
Theoretically, hydropower can step in when wind turbines go still, but barriers to this non-polluting resource serving as a backup are largely policy- and regulation-based, according to recent research. Hydroelectric dams are controlled by guide curves that account for drinking water and droughts. They cannot simply release water to meet some electricity demand or hold back water when electricity is in low demand.
As climate change begins to take the spotlight again as a political issue in the U.S., a once radical idea has resurfaced among both Republicans and Democrats: a carbon tax. On Tuesday, a conservative think tank held discussions about it while a more liberal think tank released a paper on it. And the Congressional Budget Office issued a 19-page report on the different ways to make a carbon tax less burdensome on lower income people.
Increasing demand for bioenergy feedstock is generating land-use conflicts and food vs. fuel controversies. An team of 11 scientists from seven European countries and the United States have recently published a study that gives scientific background to the debate. It supports a reassessment of the land available for bioenergy feedstock production.
Shale gas drilling has attracted national attention because advances in technology have unlocked billions of dollars of gas reserves, leading to a boom in production, jobs, and profits, as well as concerns about pollution and public health. In the debate over natural gas drilling, the companies are often the ones accused of twisting the facts. But scientists say opponents sometimes mislead the public, too.
A drilling company in southwestern Pennsylvania has given researchers at National Energy Technology Laboratory access to a commercial drilling site, a move that may provide some of the first solid answers to a controversial question: Can gas drilling fluids migrate and pose a threat to drinking water?
New research from North Carolina State University shows that federal requirements governing diesel engines of new tractor trailer trucks have resulted in major cuts in emissions of particulate matter and nitrogen oxides—pollutants that have significant human health and environmental impacts.
Despite concern from some scientists who believe exposure to BPA can harm the reproductive and nervous systems of humans, the U.S. Food and Drug Administration has turned down a petition from environmentalists that would have banned the plastic-hardening chemical bisphenol-A from all food and drink packaging, including plastic bottles and canned food.
Drillers require a lot of energy to recover and refine heavy, viscous bitumen from Canada’s oil sands. In the first look at the effect of air pollution from the excavation of oil sands, also called tar sands, scientists used satellites to measure nitrogen dioxide and sulfur dioxide. The effects, they say, are equivalent of a large power plant or a medium-sized city.
A U.N. climate conference reached a hard-fought agreement Sunday on a complex and far-reaching program meant to set a new course for the global fight against climate change for the coming decades. The United States was a reluctant supporter, concerned about agreeing to join an international climate system that likely would find much opposition in the U.S. Congress.
At the end of October, the United Nations Environment Programme, or UNEP, will conduct the third of five meetings to hammer out a treaty that may involve the comprehensive ban on mercury. The problem, says many health experts, is that a proposed ban might include thiomersal, a mercury compound used to prevent contamination and extend the shelf life of vaccines.
On Thursday, California formally adopted the nation's most comprehensive so-called "cap-and-trade" system. The system will be an experiment by the world's eighth-largest economy to provide financial incentives for polluters to reduce greenhouse gas emissions. Some businesses claim it will hurt job growth and increase electricity costs; proponents say it will do the opposite.
