More on a New Ozone NAAQS: EPA's Clean Air Science Advisory Committee Endorses EPA's Proposed Range

As we noted a few weeks ago, EPA has proposed lowering the NAAQS to a range of from 0.060 ppm – 0.070 ppm. Earlier this week, EPA’s Clean Air Science Advisory Committee, or CASAC, met and endorsed EPA’s proposed range. Some CASAC members did express concern about EPA’s proposed secondary seasonal standard, intended to protect crops and forests. However, overall, the CASAC seal of approval is pretty much the end of this argument.

It is important to recall how we got here. CASAC already endorsed the 0.060 ppm – 0.070 range several years ago, before EPA’s last ozone standard was issued. It was EPA’s refusal to follow the CASAC recommendations, and instead propose a 0.075 ppm standard, which led to litigation challenging the standard and the current controversy. 

It is difficult to overstate the weight given the CASAC’s views. Indeed, EPA’s fine particulate standard was vacated in significant part because EPA failed to follow CASAC’s recommendations.

Thus, a standard that does not comport with CASAC’s recommendations would likely be rejected by the courts as arbitrary and capricious. However, I suspect that CASAC’s influence also runs the other way. Assuming that EPA does indeed promulgate a revised NAAQS in the 0.060 ppm – 0.070 ppm range, and assuming that industrial interests challenge the new standard, it will be very difficult to establish that the new standard is arbitrary and capricious if it has been endorsed by CASAC. 

As I noted in connection with the fine particulate standard, it’s not obvious to me that this is a good thing. Depending on whose ox is being gored, anyone can get up on a soapbox and say that they want science to be free of politics. However, these are really policy decisions. It’s one thing to acknowledge that these are complicated issues and we thus have to allow Congress to delegate its authority to the EPA administrator. It’s another effectively to delegate the decision further to the CASAC, which is about as obscure an acronym body as we have. Do we really want standards which will result in compliance costs in at least the tens of billions of dollars being made by groups which truly are not accountable in any meaningful way?

Dog Bites Man; Compliance With New NAAQS To Be Costly, Difficult

As I noted on Friday, EPA has proposed to revise the NAAQS for ozone to a range of from 0.060-0.070 ppm, a reduction from the 0.075 ppm standard promulgated in 2008 by the Bush administration.  EPA’s analysis of the available date indicates that 650 counties – out of 675 counties which have ozone monitors – would be in violation of a 0.060 ppm standard. For those counting, that’s more than 96% of all counties in nonattainment. Even if the standard were set at 0.070 ppm, 515 counties would be in non-attainment.

In fact, EPA estimates that, even by 2020, 203 counties would remain in nonattainment at 0.060 ppm and 99 counties would be in nonattainment at 0.070 ppm. EPA’s estimate is that the cost to comply with a 0.060 standard would be $52B to $90B per year in 2020. I confess that I have not reviewed the rule closely enough to know exactly what that means, given EPA’s prediction that more than 30% of all counties would not be in compliance at that time. We’re going to spend $52B to $90B per year to comply with the standard – and still not meet the standard?

Coming Soon to a Vista Near You: Clearer Air; More Expensive Compliance

 

On Wednesday, EPA released a proposal to reduce the primary National Ambient Air Quality Standard for ground-level ozone from the 0.075 ppm standard set by the Bush administration in 2008 to a range of from 0.060-0.070 ppm. EPA also proposed to set a secondary standard intended to protect sensitive ecological areas, such as forests and parks.

As almost everyone knows, the 2008 standard was, to put it mildly, controversial from the start. The proposal today was based on recommendations made to EPA by its science advisors prior to the 2008 rulemaking. Following apparent intervention from the White House, then EPA Administrator Stephen Johnson set the primary standard above the scientific recommendation and declined to promulgate a secondary standard. Not surprisingly, a number of environmental organizations and public heath groups sued EPA over the failure to promulgate a new NAAQS consistent with the scientific recommendations.

Given that the Supreme Court already ruled, in Whitman v. American Trucking Associations, that EPA may not consider cost in setting NAAQS (and given the Bush EPA record before appellate courts), the 2008 standards always had “arbitrary and capricious” written all over them, so it’s no surprise that the Obama administration revisited the issue. Nonetheless, it is worth noting that, unlike most of EPA’s rules, the projected benefits of this rule may not even exceed the costs.  According to EPA, the benefits of the rule would range from $13B to $100B, while the costs are projected to range from $19B to $90B.  Not much of a net benefit, it seems to me.  (I'm still waiting for Cass Sunstein to ride to the rescue of cost-benefit analysis in this administration.)

EPA expects to finalize the rule by August 31. Then the rubber really hits the road – when states have to revise SIPs in order to meet the new standards.

 

EPA Might Require More Airborne Lead Sampling

EPA announced this week that it was granting a petition for reconsideration of the final National Ambient Air Quality Standards for lead, specifically the portion requiring monitoring of lead emissions near certain sources. The petition was brought in January by a number of environmental organizations and groups concerned about childhood lead poisoning. 

The existing lead monitoring requirements were finalized in October 2008, at the same time that EPA tightened the national air quality standards for lead for the first time in 30 years. EPA reports that the revised standards are 10 times more stringent than the previous standards and require states to place monitors near sources that emit one or more tons of lead a year. They also require a monitor to be operated in each of the 101 urban areas with populations greater than 500,000 to gather information on the general population’s exposure to lead in air.

As part of the reconsideration, EPA will evaluate whether additional monitoring near industrial sources and in urban areas is warranted. EPA notes in its fact sheet that it is not reconsidering the lead standards, and that implementation of those standards and the existing monitoring requirements will move ahead on schedule.  States are required to make recommendations for areas to be designated attainment, nonattainment, or unclassifiable by October 2009.

If EPA decides to revise the lead monitoring requirements later this summer, it would issue a final rule in the spring of next year, following public review and comment.

 

D.C. Circuit Remands Phase 2 Ozone Rule: Another Defeat for Cap and Trade Programs

Last Friday, in NRDC v. EPA, the Court of Appeals for the D.C. Circuit struck down parts of EPA’s Phase 2 rule for achieving compliance with the ozone NAAQS. The most important part of the ruling was the Court’s conclusion that EPA could not rely on compliance with the NOx SIP Call to satisfy the requirement that sources in an ozone nonattainment area demonstrate achievement of reasonably available control technology, or RACT. The basis for the decision was the Court’s conclusion that the plain language of the relevant portions of the CAA did not allow use of a cap-and-trade program to substitute for the source-specific compliance requirements imposed by the statute.

In this case, § 172(c)(1) of the CAA “requires that nonattainment areas achieve ‘such reductions in emissions from existing sources in the area’ as can be achieved by the adoption of RACT.” For the Court, this was simple and dispositive.

Thus, the RACT requirement calls for reductions in emissions from sources in the area; reductions from sources outside the nonattainment area do not satisfy the requirement.

In other words, a cap and trade program won’t do, if it allows sources to avoid explicit statutory requirements. There is nothing in the Act that precludes layering a cap-and-trade program on top of RACT requirements – but that would defeat the purpose of the cap-and-trade program, which is to allow emissions reductions to be made wherever they can be achieved most cost-effectively. To require minimum reductions at all facilities precludes such cost-effective decisions.

Frankly, while I’m a fan of cap-and-trade programs, the decision is neither unreasonable nor surprising, after the decision in North Carolina v. EPA striking down the parallel provision in the Clean Air Interstate Rule. As courts like to say (especially when Supreme Court confirmation hearings are under way), their job is not to make good policy; it is to interpret and enforce the law. If Congress wants to expand the role of cap-and-trade programs, it knows how to do so.

Of course, the elephant in the room is climate change legislation. If Congress does not enact a bill, North Carolina v. EPA and NRDC v. EPA circumscribe EPA’s discretion in implementing a cap-and-trade program for greenhouse gases under existing law.  I take the point made by Administrator Jackson and environmentalists that, if no one wants to regulate churches and schools, then EPA can probably figure out a way to do so.  However, exercise of such discretion is not the same as promulgating rules that will ensure that those facilities which are the subject of regulation have the flexibility to reduce greenhouse gas emissions in the most cost-effective manner possible.  

Is anyone in Congress listening?

Injunctive Relief under the CAA; United States v. Cinergy

Last week, Judge Larry McKinney issued an order requiring to shut down three coal-fired generating units at its Wabash Station facility by no later than September 30, 2009. The decision actually struck me as a thoughtful analysis of injunctive relief issues in a situation where a violation of NSR regulations had already been proven. Although the decision has gotten most press for the order shutting down the units, it covers a number of issues important to injunctive relief situations, and there are some nuggets which are potentially useful to generators; it is not a one-sided decision. Here are some highlights:

The shut-down order – although significant, is not as earth-shattering as it seems. Cinergy gave the judge little choice by testifying that it would not be economic to install pollution controls on the units, given their age and size. The fight was thus about when, not whether, the units would be shut down. The judge was clearly annoyed that, following the liability finding, Cinergy had seemingly taken no action to plan for a shut-down. The judge, in response to reliability concerns, did allow the units to operate through the summer of 2009.

Irreparable harm discussion – a few noteworthy aspects here

The court relied on modeling which demonstrated that Wabash emissions contributed to PM2.5 levels downwind

The court noted that contributions of “just a few tenths of a ug“ can be significant when an area is on the border between compliance and noncompliance.

Like the court in the TVA injunctive relief case we posted about earlier this year, the court specifically noted that adverse health affects can occur at levels below the NAAQS

The court rejected the plaintiffs’ argument that acid deposition and mercury emissions from Wabash had caused irreparable harm, concluding “that Plaintiffs did not provide sufficient nexus between the relevant excess emissions and the negative … effects. 

In a win for generators, the court rejected the plaintiffs’ position that BACT for NOx emissions in 1989 was SCR technology. This is an important issue, because EPA and the states will sometimes try to take the position that unproven technologies are nonetheless BACT. The decision squarely rejects that argument.

Surrender of SO2 allowances. The court required Cinergy to surrender SO2 allowances equal to the excess emissions from the May 2008 jury verdict to the time the units are shut-down. However, it is important to note that the Plaintiffs had requested that the court order Cinergy to install BACT on larger units at the Station that had not violated NSR rules. The court rejected that argument, noting that the Plaintiffs’ proposal “does not bear an equitable relationship to the degree and kind of harm it is intended to remedy …. Imposition of such a remedy is punitive in nature.”

In sum, although the decision is important, it is not surprising in context. Indeed, the finding on BACT, which was favorable to Cinergy, may have the most precedential significance.

Another Loss For the Bush EPA; The D.C. Court of Appeals Remands the Fine Particulate Standard

The batting average of the Bush administration EPA in appeals of its regulatory proposals may now have dropped below the proverbial Mendoza line. This week, the Court of Appeals for the District of Columbia remanded a substantial part of EPA’s particulate rule. That the Bush administration could achieve results where the Mendoza line is even a close metaphor is a testament to just how low its stock has fallen in the courts.

The case itself is important for a number of reasons, but is too lengthy for detailed analysis here. Highlights include:

  • First, the basic holding: the court remanded EPA’s primary annual standard for PM2.5, because EPA did not justify that the 15 ug/m3 standard was sufficient to protect public health with an adequate margin of safety. Second, the court also remanded EPA’s determination of the secondary, public welfare, standard for PM2.5.
  • The court gave great weight to the role of the Clean Air Science Advisory Committee (CASAC) and staff recommendations in the regulatory process. After this decision, EPA is going to think twice about choosing a regulatory course difference than that recommended by CASAC and staff. On balance, I think that this is a bad thing and more evidence of the collateral damage from the extreme positions taken by the Bush administration. After all, while the Clean Air Act sets some boundaries, these are ultimately policy decisions that should be made by the President and his or her chosen staff, not by a committee no one’s heard of or low-level staff.
  • Unlike the chaos created when the court vacated the CAIR regulations, the court appears to have learned its lesson. This time around, the court remanded the rule, but left the standard in place for now.
  • The court’s decision to remand the public welfare standard will have implications for current efforts to implement the its Regional Haze Rule. The extent to which this decision throws Haze Rule implementation back to the drawing board may not be known for some time.

How many more cases can the Bush administration lose after it’s already out of office? At least one. Greenwire reports today about speculation that this decision means that the EPA rules regarding the nitrogen oxide NAAQS may also be in trouble.

The interesting question in all this is the extent to which the abysmal record of the Bush EPA in defending its decisions in the courts will damage EPA’s credibility and thus result in a long-term weakening of the deference given EPA by the courts. At this point, my assumption is that, in the long run, these cases will be seen as an aberration and courts will resume their prior practice of granting EPA substantial deference. Of course, whether that is a good thing or not is a separate question.
