EPA Lowers the Ozone Standard to 70 PPB: Industry Isn’t Happy, But It Should Be

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, fortune-teller with a shining crystal ballbut 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

Yawn: EPA Promulgates New Fine Particulate Standard

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

Clean Air Grab Bag

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

CASAC Weighs in on the Ozone NAAQS: Might the Clean Air Act Require a Standard Below Background?

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

MassDEP Issues Its Decision on the Palmer Bio-mass Facility: Right on the Merits, Wrong on Standing

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

More on Back-Up Generators: NESCAUM Raises Concerns

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

Two Wins in a Week for EPA on NAAQS: The DC Circuit Upholds EPA’s New SO2 Standard

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

Not a Good Start for Challenges to EPA NAAQS Revisions: The District of Columbia Court of Appeals Affirms EPA’s New NOx NAAQS

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

EPA Proposes Revisions to the PM 2.5 NAAQS: How Much Will It Matter?

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

One More Ozone Post: Who Will Act First, EPA or the Courts?

roseanne roseannadannaFollowing 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

The Wheels of EPA’s Ozone Reconsideration Have Stopped Grinding Completely: Obama Tells EPA to Stop

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

The Wheels of EPA’s Reconsideration of the Ozone Standard Grind Slowly — Time Will Tell How Finely

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

Just in Case You Thought EPA Could Go On Its Merry Way in the Absence of Climate Legislation

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

Traditional Pollutants Definitely Still Matter: EPA’s Draft Review Recommends More Stringent Particulate Standards

Last week, I posted about improvements in air quality since 1990. It’s a good thing air quality is improving, because, at the same time, the science keeps suggesting that ever lower pollutant levels pose risks to public health. The latest news was EPA’s draft review of the appropriate level at which to set the National Ambient Air Quality Standard for particulate matter.

EPA most recently revised the PM standard in 2006,… More
