Last week, the Court of Appeals for the District of Columbia struck down EPA’s rule implementing the 2008 ozone standards. My primary take-away? The structure of the Clean Air Act is so dense and so complicated that it gives me a headache, and I do like to think I’m something of an expert. Those of us who believe in government regulation need to be honest and admit that there’s a reason why some people become Libertarians. … More

An article published Friday in Science reports that the Antarctic ozone hole is healing. As the article notes, there was some previous evidence about global improvement in stratospheric ozone levels, but this is the first to document improvement in Antarctica.
Aside from the fact that good news is always welcome, it’s also a useful reminder that environmental regulation can work. In the developed world,… More
Prognosticating the Ozone Standard Litigation: EPA to Win, Environmental Petitioners to Place, Murray Energy to Show
Earlier this week, the “Public Health and Environmental Petitioners” challenging EPA’s decision not to reduce the ozone standard below 0.070 ppm filed their “Non-Binding Statement of Issues.” My crystal ball still tells me that the most likely outcome is that the Court of Appeals upholds EPA’s 0.070 ppm standard.
On Thursday, EPA finally released its final rule revising the ozone NAAQS to 70 ppb. I do not spend much time peering into a crystal ball, but I will go out on a limb and say that the industry challenges to the rule will fail. Just ain’t gonna happen.
The environmental group challenges pose a more interesting question. There’s a fair bit of evidence of health impacts below 70 ppb,… More
Half a Loaf May Not Be Too Bad: The 9th Circuit Affirms Most of EPA’s Approval of the San Joaquin Valley SIP
Earlier this week, the 9th Circuit Court of Appeals granted part of a petition challenging EPA’s approval of California’s SIP for ozone and PM 2.5 in the San Joaquin Valley. While the trade press has been focusing on the partial reversal, I think that EPA won much more than it lost.
What did it lose? California’s plans for complying with the ozone and PM 2.5 NAAQS relied in part on emissions reductions to be attained as a result of California’s authority under the CAA to impose more stringent mobile source emissions standards than are applicable nationally. … More
Yesterday, EPA finally proposed a revised ambient air quality standard for ozone – except that the agency is still hedging its bets. The Clean Air Science Advisory Committee had previously supported a revised ozone NAAQS of 0.060 to 0.070 ppm. EPA has narrowed the range slightly, proposing a revised NAAQS of from 0.065 to 0.070 ppm, but still has not yet picked a number.… More
On Friday, EPA released its “Policy Assessment for the Review of the Ozone National Ambient Air Quality Standards.” EPA staff concluded:
that it is appropriate in this review to consider a revised primary O3 standard level within the range of 70 ppb to 60 ppb. A standard set within this range would result in important improvements in public protection, compared to the current standard,… More
As we have noted previously, EPA has had difficulty in promulgating a revised National Ambient Air Quality Standard for ozone. Whenever the revised NAAQS is issued – and EPA is under court deadline to propose a draft by December 1, 2014 and a issue a final by October 1, 2015 – the actual standard that EPA is likely to issue is coming into focus.
Late last week,… More
On Monday, EPA released its second external review draft of an updated Policy Assessment on the national ambient air quality standard for ozone. It also released updated draft risk and exposure assessments. To no one’s surprise, the new drafts confirm support for lowering the ozone NAAQS from 75 ppb to a range of 60 ppb to 70 ppb.
Why is this not a surprise? … More
What Do Midwestern States Have In Common With Groucho Marx? Ask Them Whether They Want to Be Part of the Ozone Transport Region
As the Supreme Court gets ready to consider the validity of EPA’s Cross-State Air Pollution Rule, some of the Northeastern and Mid-Atlantic states are taking another tack to address at least part of the air pollution transport issue. They have petitioned EPA under § 176A of the Clean Air Act to add Illinois, Indiana, Kentucky, Michigan, North Carolina, Ohio, Tennessee, Virginia, and West Virginia to the Ozone Transport Region established under § 184 of the CAA.… More
Mississippi v. EPA: Support of the Clean Air Science Advisory Committee is Not Necessary to Affirm EPA’s NAAQS
On Tuesday, in Mississippi v. EPA, the Court of Appeals for the D.C. Circuit affirmed EPA’s 2008 NAAQS for ozone of 0.075 ppm. However, it remanded EPA’s decision to set the secondary NAAQS, for public welfare, at the same 0.075 ppm level. With respect to the primary standard, the Court gave short shrift to industry and red-state challenges that the standard was too stringent. This is not surprising,… More
There have been so many developments recently on the air front (and I’m so far behind due to an appellate brief) that I thought I would combine a few recent items.
First, oral arguments were heard Monday on the challenges to the Bush EPA ozone NAAQS of 0.075 ppb. As I have previously noted, the Court of Appeals for the District of Columbia Circuit has made pretty plain that EPA cannot ignore the recommendations of the Clean Air Science Advisory Committee in setting the NAAQS. … More
The Daily Environment Report last week provided an update on the current status of EPA’s development of a new National Ambient Air Quality Standard for ozone. The current 8-hour standard of 75 ppb is going to be revised downward; EPA currently plans to issue a final rule by September 2014.
Following EPA’s decision last week to scrap its reconsideration of the 2008 ozone National Ambient Air Quality Standard, the parties to the litigation challenging the 2008 standard are back in court. This week, EPA submitted a brief to the Court of Appeals, which was pretty much a six-page version of Roseanne Roseannadanna’s “Never mind.” After telling the Court for years that it should defer to EPA’s reconsideration process – a decision on which was always just around the corner,… More
Yesterday, in commenting on the court battle over EPA’s reconsideration of the ozone NAAQS, I said that I would be surprised if EPA doesn’t issue the new standard within six months. Oops. My bad. Today, President Obama directed EPA to give up on the reconsideration effort. It’s difficult not to be cynical about the White House decision. As much as I admire Cass Sunstein, his letter to EPA providing the basis for the White House decision is not persuasive. Basically,… More
