This Week's Air/Climate Smorgasbord

After a relatively quiet period, there were a number of items of interest on the air/climate front this week. First, AEP announced that upcoming pollution controls would result in shutting down 6,000 megawatts of coal-fired capacity, or 25% of its coal fleet. AEP also announced that it would spend $6 billion to $8 billion in bringing the rest of its fleet into compliance.

On the flip side of this issue, the Bipartisan Policy Center issued a report concluding that compliance with the various EPA rules in the works (Clean Air Transport Rule, Utility MACT Rule, coal combustion ash rule, Clean Water Act intake structure rule, and NSPS for GHG) would not have a significant impact on electric system reliability. The quick summary is that most of the plants that will close are uncontrolled, older, smaller, plants that already don’t run much, particularly with natural gas prices low. The report acknowledges that some of these small plants are important in addressing peak loads in some areas, but concludes that concerns in those areas can be addressed with appropriate planning.

Next came news that EPA has reached agreement to delay its second round GHG NSPS proposal from July 26, 2011 to September 30, 2011 – though the final rule is still targeted for May 26, 2012. EPA has received extensive comment on this issue and my take is that there is no hidden agenda here; EPA is just trying to take those comments into account and be responsive, where possible.

Finally, former Representative Bob Inglis, whose support for action on climate change was sufficient to get him defeated by a Tea Party Candidate in the GOP primary in 2010, has announced formation of what is described as a “conservative coalition” to address climate change. Money quote:

Conservatives typically are people who try to be cognizant of risk and move to minimize risk. To be told of risk and to consciously decide to disregard it seems to be the opposite of conservative…. What I hope to do is be part of an effort that calls conservatives to return to conservatism and to turn away from the populist rejection of science.

All I can say is that I wish former Representative Inglis the best of luck in that endeavor.

Biggest Thing to Happen to TVA Since the Snail Darter

Thursday afternoon, EPA and the Tennessee Valley Authority announced one of the largest pollution reduction consent decrees in US history – resulting in between $3 to $5 billion of investment in air pollution controls, and retirement of almost one-third of TVA’s coal-fired generating units within the next few years.  Over the next decade, it will reduce TVA's total emissions of nitrogen oxides by 69% and sulfur dioxide by 67%.  Although the agreement provides a timely victory for EPA amid the current backlash against it in Congress, the settlement actually relates to a New Source Review (NSR) suit commenced by EPA during the Clinton Administration in 1999.  The consent decree resolves all alleged past preconstruction violations, as well as alleged violations of the New Source Performance Standards and Title V regulations.

The TVA operates 59 coal-fired boilers at 11 plants in Alabama, Kentucky and Tennessee, and supplies power to around 9 million people in its service area that spans most of the southeastern US. The settlement involves all 11 plants, and includes an obligation to address 92% of TVA’s coal-fired system between 2011 and 2018 by either installing state of the art pollution controls like SCRs and FGD or repowering with renewable biomass. Another 18 coal-fired units, about 16% of TVA’s coal-fired generating system, totaling 2,700 MW of capacity, will be permanently retired – the largest retirement commitment seen under EPA’s Coal-Fired Power Plan initiative, which has settled 22 such NSR cases so far.  However, Greenwire reports that, even before today's announcement, TVA was already planning to retire about 1,000 MW of coal-fired capacity.

I found the option to repower the units with renewable biomass to be particularly interesting, especially given EPA’s current proposal to continue studying biomass emissions for three years before requiring Clean Air Act permits for greenhouse gas emissions from biomass sources.  In the agreement, “Renewable Biomass” is defined very broadly, with no time-frames or extensive restrictions. Instead, it includes, in part, organic matter that comes from forests or grasslands, as well as residues and byproducts from agriculture, forestry and paper industry. Under the agreement, the repowered units would be deemed “new” emission units, themselves subject to New Source Review and other permitting requirements.

The settlement also includes $10 million in penalties -- $8 million paid to EPA, $1 million paid to Tennessee and $500,000 each paid to Alabama and Kentucky -- as well as $350 million in environmental mitigation projects, including $240 million to be spent on TVA-run energy efficiency projects and $60 million to be divided among Alabama, Kentucky, North Carolina and Tennessee for the states to implement projects of their choosing, so long as they're within the categories specified in the consent decree.

What Does It Take to "Displace" Federal Common Law? The States Have Their Say

Last month, in discussing the Administration’s brief in the American Electric Power case, I praised the nuanced and persuasive approach that the Administration took in seeking reversal of the 2nd Circuit opinion allowing the states' public nuisance climate litigation to go forward. The states seeking to prosecute the law suit have now filed their brief and it turns out that they also do nuance. I still think that the Supreme Court will reverse, however.

I’m not going to get into the standing issue. I don't believe that the states should have standing, but it’s not obvious, given the result in Massachusetts v. EPA, that the Supreme Court will agree.

I find the displacement issue more interesting. The 2nd Circuit held that the Clean Air Act had not displaced federal common law, because EPA wasn’t actually regulating GHG. Of course, EPA has reversed course and, at least until the GOP in the House has its way, it does now regulate GHG under the CAA. As a result, as the Administration put it in its brief:

Although EPA has not yet done precisely what plaintiffs demand here…, that is not the relevant test. … The question is whether the field has been occupied, not whether it has been occupied in a particular manner.

The plaintiff states disagree. In what is probably a shrewd concession, the states acknowledge that, were EPA to issue new source performance standards for GHG, such standards would displace federal common law, because, while they would not directly subject existing facilities to controls, they would lead to follow-on regulation by EPA requiring states to impose GHG standards on existing plants. Until existing plants are regulated, according to the states, common law has not been displaced. Thus, the states argue, the Supreme Court should either affirm the 2nd Circuit or simply dismiss the appeal – the states further acknowledge that, on remand, the District Court could reasonably stay the nuisance case to see if EPA in fact issues NSPS for GHG.

Shrewd and nuanced, but I’m still not buying it. I think that once EPA’s GHG regulatory program came into effect, federal common law was displaced. Of course, I don’t get a vote, so we’ll have to wait for the Supreme Court to decide the case.

NSPS, CAMR, CATR, BACT, PSD, UGH (The Last One's Not an Acronym)

Back in my public policy days, there was much discussion of “muddling through.” When I look at recent developments on the climate and air regulation front, I just see a muddle. First, we have Gina McCarthy, saying that EPA wants to walk before it runs, and assuring utility executives that New Source Performance Standards for GHG emissions will not have a “dramatic effect.” McCarthy further said that EPA will take a “common sense approach,” comparing it to EPA’s approach to the GHG BACT guidance, which she described as “not overly ambitious.”

At the same time, the first PSD permit for GHG has been issued, to Nucor Corporation's direct reduced iron manufacturing facility in Louisiana. While praising Nucor for utilizing DRI technology, which apparently generates lower GHG emissions than plants utilizing coke, and while acknowledging that this was one of the first GHG PSD applications, EPA raised two concerns that may be troubling to permittees. First, the permit would require a package of good combustion practices, but did not include a numerical limit for GHG emissions. EPA commented that the permit had not justified why a numerical limit would not be feasible. 

Second, EPA noted that the permit did not provide a basis for the conclusion that carbon capture and sequestration, or CCS, would not be feasible for this project. EPA’s comments referred to EPA’s December 2010 GHG BACT guidance as noting that CCS is generally available for iron and steel manufacturing facilities.

To EPA, the BACT guidance may be common sense. However, to the regulated community, it creates uncertainty. Uncertainty means risk. Risk means costs. Will EPA insist on numerical standards? What are those standards going to be? Based on the EPA's comments regarding CCS, it appears that EPA may be intending to treat the GHG BACT guidance as having the force of regulation. If so, we are stuck with the worst of both worlds – the absence of the protection provided by notice and comment rulemaking and the absence of the flexibility in utilizing guidance, rather than regulation. 

Moreover, EPA does not appear to understand the scope of the uncertainty created by such actions. EPA may allow the Nucor facility to proceed without CCS, once the permit application is amended to include an explanation of the infeasibility of CCS. However, there is no point in requiring such an analysis unless there is some possibility that CCS may be required. The regulated community – and state regulators – are left wondering under what circumstances CCS would be considered feasible. The same is true with the analysis of coal and natural gas. It’s difficult to read the BACT guidance without concluding that, under some circumstances, BACT for coal might be gas. However, we don’t know yet what those circumstance would be. 

On the other side of the aisle, as it were, we have the muddle that is Congressional opposition to EPA GHG regulation. Fred Upton, Chair of the House Energy and Commerce Committee, has described the NSPS standards as a “backdoor attempt to implement their failed job-killing cap-and-trade scheme.” Sadly, I only wish it were so. He seems to think that describing NSPS standards as a “cap-and-trade” scheme is the worst kind of insult. However, he’s got it backwards. First, unlike the cap-and-trade plan, the NSPS regulations are required under the existing Clean Air Act as interpreted by the Supreme Court in Massachusetts v. EPA. Second, cap-and-trade was proposed precisely because it has been demonstrated to be an economically efficient way to attain pollution reductions. It’s really only fair to describe it as job-killing if you don’t believe in anthropogenic climate change. (I’m too tired to go there today.) If Congress doesn’t want EPA to kill jobs, then give it the tools to regulate as efficiently as possible. 

Moreover, as noted in the Daily Environment Report, while Congress is up in arms about EPA climate rules, Congress is extremely unlikely to limit EPA’s authority to issue the Clean Air Mercury Rule and Clean Air Transport Rule, both of which are going to have more significant impact on power generators and electricity prices than GHG NSPS.

Occupying the middle ground – if not the muddle ground – is Senator Rockefeller, attempting the most delicate of balancing acts. While still complaining about EPA’s veto of the mountaintop removal permit for the Spruce No. 1 mine and backing legislation which would delay EPA’s GHG rules for two years, Rockefeller criticized “EPA-bashing.” Rockefeller’s view is apparently just that coal is important, coal cannot survive serious GHG regulation without CCS, and CCS requires more time. We’ll see how his dance plays back home and with the Chamber of Commerce. I thought that we are now against backing particular technological solutions and I certainly believe that sooner or later, we're just going to have to bite the bullet and put a price on carbon.

For now, though, I guess we’re just muddling through.

EPA Delivers an Early Christmas Present to Electricity Generators and Refiners -- New Source Performance Standards for GHGs

Today, EPA announced settlements of litigation with states and environmental groups which will require EPA to promulgate New Source Performance Standards for greenhouse gas emissions from electric generating units and refineries. EPA will thus give those of us who practice in this area an opportunity to decide which program we find more cumbersome and ill-suited to regulate GHGs, the PSD/NSR program or the NSPS program.

As with the PSD/NSR regulations, I remain sympathetic to EPA in that, once you take Massachusetts v. EPA as a given, and if you accept the logic of the Endangerment Finding, then it is difficult to see how EPA can avoid these regulations. Moreover, EPA has described its expected set of performance standards as “modest” – though modesty, of course, is in the eyes of the beholder. 

Nonetheless, it’s not surprising that opponents of GHG regulation see this as another stick in the eye. Here is what Senator Murkowski’s spokesman, Robert Dillon, had to say:

The administration used the threat of EPA regulations as a cudgel to force Congress to pass cap and trade. It was a strategy that failed.  You've opened Pandora's box now. You've let the agency loose with these new regulations when they're interpreting the law.

Of course, it’s EPA’s job to interpret the law. That doesn’t make me happy about it.

A Mixed Verdict on NSR Enforcement?

Earlier this week, the jury reached a verdict in the Cinergy – now Duke Energy – NSR retrial. The short version is simple:

Condensor retubine – no need to go through NSR

Pulverizor replacement – requires NSR

I don’t know all of the details of the case.  For example, I don’t know if the pulverizer capacity was expanded when they were replaced.  If any readers know the details and want to share them, I’d be grateful.

The decision does call to mind a previous post, in which I suggested that environmentalists might trade elimination of the NSR program for a requirement that all existing facilities comply with NSPS by a date certain. If instead of the current NSR program, the CAA had been amended in 1977 to give existing facilities until 2002 – 25 years – to be as clean as new facilities, there would have been howls of outrage at the time from the environmental community, but today we would be in a much better place.  Although the same howls would be heard today, shouldn’t it be possible to reach a deal, particularly given the pressure old facilities will be under as a result of a cap-and-trade program, that would eliminate NSR in return for a date certain by which existing facilities have to be clean as new?  It might be 15 years later than if the deal had been struck in 1977, but that doesn’t mean it would be a bad idea now.

BTW, for a cogent economic analysis of this issue, take a look at my friend Rob Stavins' post from a few weeks ago.  I'm tempted to say great minds thing alike, but perhaps I'll just go with a great mind thinks alike.

EDF Targets EPA Landfill Methane Regulations

Opening yet another front in the effort to force EPA to take more aggressive action to combat global warming, the Environmental Defense Fund recently announced its intent to sue EPA for its failure to update emissions standards with respect to emissions of methane from landfills. As EDF has alleged, Section 111 of the Clean Air Act requires that EPA update its New Source Performance Standards every eight years. EPA last updated the landfill NSPS in 1996.

Of course, at the time EPA last promulgated landfill NSPS, climate change was not part of the equation. Now, it is. Methane is a potent greenhouse gas, 21 times more potent than CO2. Although landfills have increasingly made efforts to capture methane for waste-to-energy projects, these efforts are apparently not fast enough or comprehensive enough for EDF.

Specifically, in its 1996 promulgation, EPA determined that energy recovery from landfill methane was not available. EDF, in its Notice, cites sources indicating that energy recovery is now feasible, even at smaller landfills. 

The likelihood that EPA will revisit this issue in the limited time remaining to the current administration seems vanishingly small. However, there is no doubt that this issue will be revisited in the next administration. Given methane’s potency as a greenhouse gas, it seems likely that regulations will target this area, whether as part of a revision to NSPS or as part of a broader strategy aimed directly at climate change. Once cap and trade programs expand beyond the power generation sector, as seems likely, regulators are certainly going to be looking at reductions from landfills, among other non-power sources.
