An Update On EPA GHG Regulation Under Existing Authority

The uncertainty surrounding EPA regulation of GHG emissions under existing Clean Air Act authority was driven home for me last week when the same conference resulted in two diametrically opposed headlines in the trade press. Regarding a forum held by the International Emissions Trading Association, the Daily Environmental Reporter headline was “Existing Law Too Inflexible to Accommodate Market-Based Emissions Cuts, Executives Say.” Over at ClimateWire, the headline wasSome Companies Want EPA to Establish a CO2 Cap-and-trade System.” 

Of course, in fairness to the two publications, both headlines are true – and that’s the problem with the current EPA efforts. Notwithstanding current efforts in Congress to preclude EPA regulations, the endangerment finding seems almost certain to withstand legal challenge. Thus, GHGs will be regulated. Almost everyone wants that regulation to be in the form of a cap-and-trade program, but the last time EPA tried that without explicit Congressional authority, it was shot down in the courts. This may be why the Daily Environment Report story indicated that Vickie Patton of EDF had “pleaded” with executives to support cap-and-trade legislation.

At this point, the most likely near-term outcome appears to be no federal cap-and-trade legislation, and a stripped-down EPA regulatory program that would only apply to really large emitters, so that the inefficiencies inherent in the facility-specific BACT approach won’t appear too unreasonable, because the only people complaining about it will be some very unpopular polluters and all of my economist friends.

Or, as the Stones might have said in their more cynical moments:  Not only can’t you get what you want, but you can’t even get what you need.

BACT Update: Is BACT for a Coal Plant Natural Gas?

Last week, I reported on a decision by EPA Administrator Jackson, in an appeal from a permit issued by the Kentucky Division of Air Quality, to the effect that the developer of an Integrated Gasification Combined Cycle (IGCC) plant, which converts coal to gas for combustion, had to consider use of natural gas as BACT, because the plant already had plans to use natural gas as a startup and backup fuel.

This week, Administrator Jackson went one step further – granting an objection to a permit for a traditional coal plant in Arkansas on the ground that it did not consider IGCC as BACT. As with the Kentucky decision, the issue in the Arkansas case was whether requiring IGCC would be to “redefine” the source. Also as with the Kentucky decision, the Administrator ruled that, while requiring consideration of IGCC as BACT might be to redefine the source, neither the permittee nor the Arkansas Department of Environmental Quality had built a record sufficient to make that conclusion.

As David Bookbinder of the Sierra Club succinctly put it in Greenwire: "Control technology for conventional coal is IGCC and control technology for IGCC is natural gas." In short, the way to control emissions from a coal plant is to burn natural gas instead. 

I think that Bookbinder is exactly right concerning the import of the two decisions. I also think that the result is nuts. Can anyone say with a straight face that they really believe that this approach is consistent with the statutory intent? As I noted last week, EPA didn’t think so when they wrote in the New Source Review Workshop Manual that

applicants proposing to construct a coal-fired electric generator, have not been required by EPA as part of a BACT analysis to consider building a natural gas-fired electric turbine although the turbine may be inherently less polluting per unit product (in this case electricity).

I also think that this is what happens when the agency ties itself into knots to reach a certain result based on statutory language written in another time for another purpose. Might there be a lesson in this for EPA’s efforts to regulate GHG utilizing existing CAA authority?

When Do EPA BACT Requirements "Redesign the Source"? Not When EPA Says They Don't

Shortly before the holidays, EPA Administrator Jackson issued an Order in response to a challenge to a combined Title V / PSD permit issued by the Kentucky Division for Air Quality to an Integrated Gasification Combined Cycle, or IGCC, plant. The Order upheld the challenge, in part, on the ground that neither the permittee nor KDAQ had adequately justified why the BACT analysis for the facility did not include consideration of full-time use of natural gas notwithstanding that the plant is an IGCC facility. 

The Order may not be shocking in today’s environment – all meanings of that word intended – but the lengths to which the Order goes to avoid its own logical consequences shows just what a departure this decision is from established practice concerning BACT. BACT analyses have traditionally involved the proverbial “top-down” look at technologies that can be used to control emissions from a proposed facility. In other words, EPA takes the proposal as a given, and then asks what the best available control technology is for that facility

In EPA’s own words – from its New Source Review Workshop Manual (long the Bible for BACT analysis):

Historically, EPA has not considered the BACT requirement as a means to redefine the design of the source when considering available control alternatives. For example, applicants proposing to construct a coal-fired electric generator, have not been required by EPA as part of a BACT analysis to consider building a natural gas-fired electric turbine although the turbine may be inherently less polluting per unit product (in this case electricity).

Apt example, don’t you think? (In case you are wondering, EPA’s decision does not discuss or refer to this text from the NSR Manual.)

What was the basis for EPA’s decision here? Largely, it is that the IGCC facility will be designed to burn natural gas as well as syngas and the permittee specifically stated that it planned to combust natural gas during a 6-12 month startup period. On these facts, EPA concluded that the permittee and KDAQ had to do a better job explaining why full-time use of natural gas should be considered “to redefine the design of the source.”

As noted above, EPA went to great lengths to minimize the scope of the decision. It states that the Order:

should in no way be interpreted as EPA expressing a policy preference for construction of natural-gas fired facilities over IGCC facilities.

should not be interpreted to establish or imply an EPA position that PSD permitting authorities should conclude … that BACT for a proposed electricity generating unit is … natural gas.

does not conclude that it is not possible or permissible for the permit applicant … to develop a rationale which shows that firing exclusively with natural gas would “redefine the source.”

EPA does not intend to discourage applicants that propose to construct an IGCC facility from seeking to hedge the risk of investing in … IGCC technology by proposing … utilizing natural gas for some period….

Methinks EPA doth protest too much. If I may say so, this is a freakin’ IGCC facility. Isn’t it obvious that one doesn’t plan or build an IGCC facility if one plans to burn natural gas? Don’t you think that EPA could have taken administrative notice of what IGCC technology is?

All of EPA’s protestations about the Order’s limits may be designed to mollify IGCC supporters, but what does its rationale mean for all of the existing facilities – coal and oil – that are already capable of firing on natural gas? Next time they are subject to NSR/PSD review, must they evaluate the possibility of switching completely to natural gas? As I’ve said here before, yikes!

So We're Endangered by GHGs: Now What?

As anyone not hiding under a rock has by now probably realized, EPA officially announced Monday that it has concluded that GHG from human activity threaten public health and the environment. Since the announcement was not exactly a surprise, the question remains what impact it will have.

In the short run, the timing certainly seems intended to coincide with the Copenhagen talks and help to demonstrate to other nations that the U.S. is taking concrete steps to address climate change. We’ll see shortly how successful the endangerment finding is in that respect.

Since I spend most of my time down in the trenches, I’m more concerned with the impact of the endangerment finding on the domestic front. There are really three fronts here:

Litigation – If there was any suspense regarding whether anyone would challenge the endangerment finding, such suspense was quickly relieved by an announcement from the Competitive Enterprise Institute that it would indeed sue. CEI’s press release stated that the global warming “models are about to sink under the growing weight of evidence that they are fabrications.” Uphill battle barely begins to describe the likelihood that CEI wins that case.

Prospects for Cap-and-Trade Legislation – Notwithstanding Administrator Jackson’s protestations to the contrary, it’s hard not to see the announcement as a further prod to Congress to get moving, particularly since the Administration keeps saying that it would prefer enactment of a cap-and-trade bill. Even so, however, some members of Congress indicated that the announcement would have little impact, because the endangerment finding was expected and thus adds little new.

EPA Development of Regulations – EPA is moving forward with regulatory development, though Administrator Jackson gave no time line for when stationary source regulations would be promulgated. There was an indication that EPA would issue BACT guidance in advance of issuing NSR regulations. Notwithstanding the promise of BACT guidance, it appears that states are not ready for the brave new world of using the NSR program to regulate GHGs. ClimateWire reported that Bill Becker, executive director of the National Association of Clean Air Agencies, believes that states will have hard time getting ready to process stationary source permits by March.

I actually found the biggest take-away from the announcement to be the Administrator’s statement that she wanted EPA regulations that would be complementary to new legislation. "I don't believe this is an either-or proposition," ClimateWire reported her saying. 

Uh-oh. 

I thought that the deal had always been that legislation would substitute for regulation under the existing CAA. Otherwise, what do the administration’s statements that it would prefer legislation to regulation mean?   I’m having difficulty imagining a world with both a cap-and-trade program and NSR regulation of GHGs.

Is CO2 a Regulated Pollutant Under the Clean Air Act? Not Yet, At Least in Georgia

Earlier this week, the Georgia Court of Appeals reversed a decision of the Superior Court in Georgia that would have required Longleaf Energy Associates, developer of a coal-fired power plant, to perform a BACT analysis of CO2 emissions control technologies in order to obtain an air quality permit for construction of the plant. The case is a reprise of the Deseret Power case regarding a coal-fired plant in Utah.

The court in Longleaf Energy concluded that CO2 is not yet a regulated pollutant under the CAA, and thus that no BACT analysis is required. There were several bases for this conclusion:

The “Johnson Memo,” issued in response to Deseret Power, has not been withdrawn by EPA, though it is under reconsideration. Even EPA’s proposed endangerment finding for CO2 noted that such a finding would not make CO2 a regulated pollutant under the CAA.

As discussed in the Johnson Memo, neither the CAA nor any existing EPA regulations impose emissions limitations on CO2.

Such a finding would “preempt” Congressional and EPA decision-making on the issue and impose standards in Georgia to which facilities outside of Georgia would not be subject.

The Longleaf Energy decision is a perfectly reasonable interpretation of the CAA – but it’s not the only plausible interpretation. I mention this in order to highlight a point I have made previously. As members of Congress and stakeholders consider the costs and benefits of federal climate change legislation, they have to consider the alternative. Most people, including me, have framed the question as a comparison of the legislative option with regulation by EPA under existing authority. This is largely correct, but misses two points. First, it’s going to take EPA some time to promulgate regulations. In the meantime, there will be more Deseret Power and Longleaf Energy decisions and there is no reason to be confident that such decisions will be consistent or even reconcilable. Second, even after EPA issues regulations, the Longleaf case gives me pause as to whether such regulations would be effective in creating any kind of uniform national interpretation of these issues.

There is just no question that, in the absence of federal legislation, the resulting patchwork of regulations and federal and state decisions concerning the regulation of CO2 and other GHGs is going to be a big mess.

EPA's Roll-back of Bush-Era Rules Rolls On

The next Bush-era rule to be tossed overboard may be a big one, namely EPA's hands-off stance on regulation of CO2 for PSD purposes.   EPA  Administrator Lisa Jackson said today in a letter to the Sierra Club that the agency would grant the group's petition seeking reconsideration of former Administrator Johnson's December 18th memo which described why EPA should not regulate CO2 emissions from new coal-fired plants.  Although EPA did not stay the effectiveness of the Johnson memo, the letter emphasizes that the memo does not bind States issuing permits under their own State Implementation Plans, and cautions other PSD permitting authorities against assuming that the Johnson memo is the final word on interpreting the Clean Air Act requirements.  EPA will take public comment on concerns raised over the Johnson memo and the appeals board's decision, and plans to publish a notice of proposed rulemaking soon.

As we previously noted, the new administration was likely to be saddled with the decision of whether CO2 emissions must play a part in PSD decisions, given the Deseret Power decision that the Clean Air Act was ambiguous on whether the EPA must impose a BACT limit for CO2.   Now it looks like the Obama administration may take the issue on soon.

Is CO2 "Subject to Regulation" under the Clean Air Act? Time Will Tell (We Think).

In Massachusetts v. EPA, the Supreme Court concluded that greenhouse gases, including CO2, are “air pollutants,” the it left (barely) open the question whether CO2 is “subject to regulation” under the Clean Air Act (“CAA”). 

Following Massachusetts v. EPA, there have been a number of cases in which advocates of climate change regulation have sought to require EPA to regulate CO2 as a pollutant. One of those cases, In re Deseret Power Electric Cooperative, was just decided by the EPA Environmental Appeals Board. In Deseret Power, the Sierra Club had challenged issuance of a PSD permit issued by EPA Region 8 which would have allowed Deseret Power to construct a coal-fired power plant near Bonanza Utah. The basis for the challenge was the failure of EPA to impose a best available control technology, or BACT, limit on CO2 emissions.

Notwithstanding the decision in Massachusetts v. EPA, EPA took the position that it historically had not interpreted the term “subject to regulation under the Act” to include CO2. Moreover, it claimed in Deseret Power that it did not have authority to impose a BACT limit on CO2 emissions. The EAB firmly rejected EPA’s position that it did not have authority to impose BACT limits on CO2. However, the EAB also rejected the Sierra Club’s argument that EPA was required to impose compliance with BACT for CO2.  In fact, the EAB concluded that “the statute is not so clear and unequivocal as to preclude Agency interpretation of the phrase ‘subject to regulation under this act,’ and therefore the statute does not dictate whether the Agency must impose a BACT limit for CO2.”

So where does the Deseret Power decision leave the regulation of CO2 under the CAA?  Probably pretty much where it was before the decision was issued – that is, right in the lap of the new administration. However, if I were a betting man, I would certainly be reluctant to back new ventures that involve significant CO2 emissions unless the developer has a plan for addressing CO2 emissions.
