According to Bloomberg Environment (subscription required), EPA’s Clean Air Science Advisory Committee cannot reach agreement whether to recommend that the NAAQS for PM2.5 be lowered.  Even after two years, I guess I had not realized the extent to which the scientists relied on by this administration are willing to ignore what used to be generally known as the “scientific consensus.”

As I reported last month,… More

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

On Friday, EPA announced promulgation of its revised fine particulate, or PM2.5, NAAQS.  Why am I yawning?  Let me count the ways:

1.         Because, in 2009, the District of Columbia Court of Appeals rejected EPA’s prior effort to keep the PM2.5 standard at 15 ug/m3.

2.         Because, as I have previously noted, the Court of Appeals pretty much told EPA that it could not ignore the advice of its Clean Air Science Advisory Committee in setting the NAAQS.… 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.

Last month, the Clean Air Science Advisory Committee weighed in on EPA’s draft policy assessment for the ozone NAAQS. … More

I finally had an opportunity to review the recent Final Decision in In the Matter of Palmer Renewable Energy, concerning the proposed Palmer biomass facility. Last week, MassDEP Commissioner Ken Kimmell affirmed the Recommended Final Decision by Presiding Officer Timothy Jones, rejecting challenges by the Conservation Law Foundation to the air permit issued to the project by MassDEP. For practitioners, the case is important, but a decidedly mixed bag.… More

For those of you following EPA’s proposal to allow increased use of backup generators used in demand response programs, NESCAUM has now joined the fray. In a report released yesterday and available on its website, NESCAUM stated that:

Preliminary screening analyses indicate that uncontrolled diesel backup generators operating under the exemption included in EPA’s recent proposal could by themselves create hotspots exceeding the national health-based 1-hour NO2 air standard.… More

On Wednesday, I discussed the DC Circuit’s decision affirming EPA’s revised NAAQS for NOx. Today, the DC Circuit upheld EPA’s revised SO2 standard. The tenor of today’s decision, written by David Sentelle, another Reagan appointee (the NOx decision was written by Douglas Ginsburg), is fairly similar to that in the NOx decision. Here’s the short version of the opinion:

EPA must establish NAAQS that protect public health with “an adequate margin of safety.” For that reason,… More

Yesterday, in American Petroleum Institute v. EPA, the D.C. Circuit Court of Appeals affirmed EPA’s revisions to the National Ambient Air Quality Standard for NOx. The revisions adopted, for the first time, an hourly NAAQS for NOx, in addition to the annual standard.

API made a number of assertions that EPA had been arbitrary and capricious in its review of the scientific evidence concerning potential short-term impacts. The most important were EPA’s reliance,… More

Last Thursday, in response to a court order, EPA finally proposed revisions to the national ambient air quality standard for PM2.5. The most significant part of the rule is EPA’s proposal to lower the primary annual standard from 15 ug/m3 to a range of from 12 ug/m3 to 13 ug/m3.

At a certain level, the proposal should not really be news and should not have a significant impact. After all,… More

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

This week, EPA filed a brief with the D.C. Circuit Court of Appeals, arguing that, notwithstanding its fourth delay in issuing a decision on its reconsideration of the NAAQS for ozone, the court cannot and should not order EPA to issue a decision. Industry shouldn’t get too excited, however. In the same brief, EPA telegraphed pretty clearly, consistent with its 2010 proposed rule, that it remains on track to significantly decrease the ozone standard from the 0.075 ppm standard promulgated by the Bush administration in 2008.… More

Earlier this week, I posted about the dire prospects for climate change legislation following the fall elections. The alternative to legislation has always been regulation under existing Clean Air Act authority, so it’s appropriate as a follow-up to briefly examine the pressures on EPA as it moves forward with its stationary source GHG regulations. Two headlines from the trade press today brought home just what a tightrope EPA is walking.… More

In 1972, Christopher Stone published his seminal book “Should Trees Have Standing?” That same year, Justice Douglas posed essentially the same question in his dissent in Sierra Club v. Morton, in which he argued that inanimate objects should have standing “to sue for their own preservation.”

I hadn’t thought of this for some time, but was reminded of the issue by an article in GreenWire this week,… More
