Politico reports (subscription required) that the White House Office of Management and Budget on Friday finished review of EPA’s final rule to set state implementation plan requirements for the agency’s 2008 ozone standards.
Here’s the significance of that piece of wonky news: Even before EPA has finished telling the states how to implement the 2008 ozone standards, the agency already is well into setting new, potentially stricter standards. Regulation for regulation sake? It would be hard to find a better illustration.

With EPA opening public hearings (subscription required) on its proposed new ground-level ozone standards, it’s important that we not let some key facts get lost in the wave of comments and anecdotes that results when there’s an open microphone available.
At issue is EPA’s plan to make more restrictive the National Ambient Air Quality Standard for ozone, from the current 75 parts per billion (ppb) to between 65 and 70 ppb. The agency is collecting input until mid-March before finalizing the rule this fall.
We’ve made the case before that the existing standards are working, that our air is getting cleaner and will continue to do so with the current rule. In short, there’s no good reason to make the standards more stringent. That’s what the science shows, as experts detailed at EPA’s hearing in Washington, D.C. (here and here). Indeed, EPA’s own data shows that ozone levels have fallen 33 percent since 1980, including 18 percent since 2000.

Experts believe EPA soon will issue its proposal for the five-year review of Ozone National Ambient Air Quality Standards, perhaps as early as this week. Some important points to consider as the agency prepares what could be the costliest regulation ever imposed on Americans:
First, our air is getting cleaner under the current 75 parts per billion (ppb) standards set in 2008. EPA reports that national average ozone levels have fallen 33 percent since 1980 – including 18 percent since 2000.

A couple of data points to remember with EPA poised to propose new, lower ground-level ozone standards, perhaps as soon as next month:
Air quality is and has been improving under the current, 75 parts per billion (ppb) standards, which are still being implemented across the country. Meanwhile, EPA reports national average ozone levels have fallen 33 percent since 1980 and 18 percent since 2000.
Against that backdrop, EPA staff reportedly is recommending a new primary ozone standard of between 60 and 70 ppb, which could put 94 percent of the country out of compliance – potentially stunting job creation and economic growth for little, if any, health benefit.

One of the oft-repeated claims of ethanol producers is that higher-ethanol blend fuels like E15 are better for air quality than the E10 gasoline that’s the staple of the U.S. fuel supply. Short response: No. And while we’ve addressed the ethanol/air quality claim recently here and here, spurious assertions often have more lives than Lulu, my daughter’s cat. So let’s look at the facts and credible research again.
We’ll underscore “facts and credible research,” because an advocacy group is promoting a study on ethanol, air quality and potential cancer risks that isn’t an original study at all. Rather, it’s an overly simplistic exercise in data aggregation that ignores the confounding effects of different test procedures, laboratories and fuel properties. In other words, it’s a crummy analysis that would send real scientists running in the other way.

Reuters: Rising U.S. imports of crude oil from Canada's oil sands have not increased greenhouse gas emissions from the country's oil refineries because they have been offset by refining of cleaner domestic crudes, a report from a private sector think tank said on Monday.
The report, from industry consultants IHS CERA, comes as the Obama administration moves to cut greenhouse gas emissions from the U.S. power sector by 30 percent from 2005 levels by 2030, under new rules aimed at reducing America's longstanding reliance on burning coal to generate electricity.
The oil sands sector has faced frequent criticism from environmentalists concerned about greenhouse gas emissions. U.S. imports of carbon-rich Canadian oil-sands crudes grew by 900,000 barrels per day to more than 2 million bpd between 2005 and 2012, according to the IHS CERA report.
It said they did not result in higher greenhouse-gas intensity from the energy sector, however, as other crudes imported from abroad were supplanted by so-called tight oil from domestic shale-oil deposits.
