Judges Overturn Bush Bid to Ease Pollution Rules – New York Times

But on Friday, the court said the agency went too far in 2003 when it issued a separate new rule that opponents said would exempt most equipment changes from environmental reviews — even changes that would result in higher emissions.

With a wry footnote to Lewis Carroll’s “Through the Looking Glass,” the court said that “only in a Humpty-Dumpty world” could the law be read otherwise.

“We decline such a world view,” said their unanimous decision, written by Judge Judith W. Rogers, an appointee of President Bill Clinton. Judges David Tatel, another Clinton appointee, and Janice Rogers Brown, a recent Bush appointee, joined her.

The winners this time —more than a dozen states, including New York and California and a large group of environmental organizations — hailed the decision as one of their most important gains in years of litigation, regulation and legal challenges under the Clean Air Act.

The provision of the law at issue, the “new source review” section, governs the permits required at more than 1,300 coal-fueled power plants around the country and 17,000 factories, refineries and chemical plants that spew millions of tons of pollution into the air each year.

The proposed rule would have allowed powerplants to avoid putting new controls in as long as the cost of equipment did not exceed 20% of the replacement cost of the plant. Fuzzy math, anyone! This would have let to major incentives to not build new plants using cleaner technology, but keep the “grandfathers” running. A lot of the old plants were exempted from some of the strict controls by being grandfathered into the act. Well, call me cruel, but grandfathers eventually die! I thought of this proposed rule as the “Bionic Grandpa” provision! Glad that the courts did not like it.

The Beeb does it again. Best use of simple graphics to clearly explain science.

1. Surface currents carry warm, salty water from the tropics.
2. The water cools, its density increases and it sinks to the deep ocean.
3. The cold water flows back to the equator, driving the “ocean conveyor” which in turn contributes to the Gulf Stream that warms northern Europe.
4. As ice melts, freshwater dilutes the warm salty water from the tropics.
5. The water becomes less dense so does not sink as fast, weakening the “conveyor” and therefore possibly disrupting the Gulf Stream.

Gulf Stream

Dramatic temperature shifts have happened in the past, driven partly by changes in a major ocean currents.

A “great ocean conveyor” helps transport heat around the globe via surface and deep-sea movements of water.

Scientists are exploring whether global warming might slow or shut it down – a scenario considered “low probability, high impact”.

This could disrupt mostly wind-driven surface currents such as the Gulf Stream, which brings milder weather to Northern Europe.

Low Probability, High impact indeed, aka the “Hell Freezes Over” Scenario. The Gulf Stream example is one of my favorites, check all the other animation out, it is great.

Environmental Protection Agency – EPA Press Release: EPA Report Shows Decrease in Toxic Chemicals Released

(Washington, D.C. – April 12, 2006) The amount of toxic chemicals released into the environment decreased four percent from 2003 to 2004 according to the Environmental Protections Agency’s Toxics Release Inventory (TRI) released today.

“Today’s report demonstrates that economic growth and effective environmental protection can go hand-in-hand,” said Linda Travers, acting assistant administrator for the Office of Environmental Information. “We are encouraged to see a continued reduction in the overall amount of toxic chemicals being released into the environment.”

Significant decreases were seen in some of the most toxic chemicals from 2003-2004.

· Dioxin and dioxin compounds, which decreased by 58 percent,
· mercury and mercury compounds, which were cut by 16 percent and
· polychlorinated biphenyls (PCBs) went down 92 percent.

Why, that is positively great news, especially on the dioxin and PCB front. Since pictures are nicer and data from the last 5 years provides a little more context, why don’t we use the Toxics Release Inventory Explorer to pull some information together…

No drastic decreases, dioxin releases during 2004 are close to those during 2000. Wow, seems like 2003 was an especially bad year, the PCB release is off the charts. One landfill facility was responsible for more than 80% of the release. Kinda useless to point to trends caused by single data points, but I guess that’s what press releases are for, pick on some fortuitous piece of data and hope that the media is lazy enough to not spend a little time looking into the story.

The grist picks (up) on this release as well.

Meanwhile, the EPA is considering a loosening of regulation in this regard, read this Seattle Post-Intelligencer article for more details.

The EPA inventory “keeps that pressure on to keep those emissions down,” Hansen said. That’s the purpose of this kind of public information or “right-to-know” program.

The EPA has not made a final decision on the changes it has proposed — namely, requiring emissions reports every two years instead of annually and raising the volume of chemicals that have to be released before a report is required.

“The jury is still out,” said Brook Madrone, TRI program manager for the regional EPA office.

Information is power (always end on a cliche!)
