President Obama released his Climate Action Plan to much fanfare on June 25, 2013 in an attempt to reduce the country’s greenhouse gas emissions “in the range of 17 percent below 2005 levels by 2020.” 2 The centerpiece of the plan is to have the Environmental Protection Agency (EPA) issue carbon dioxide (CO2) standards for new and existing power plants, which account for roughly one-third of this country’s emissions. 3
Obama’s announcement sent the news media and politicians into a frenzy, with vast proclamations on both sides about these regulations shutting down a large number of power plants, increasing electric costs, and killing the coal industry. 4 But as this Essay will illustrate, these proclamations are exaggerated. The new regulations are unlikely to cause any significant retirements of existing coal-fired power plants (the largest emitters by far) 5, and at best will lead to no more than about a five percent reduction in power plant emissions once fully implemented around 2020. The reason for this lackluster result is not President Obama’s fault. The Clean Air Act – which governs the EPA’s ability to issue these standards – and more than forty years of federal court and EPA decisions interpreting the Act leave the EPA’s hands tied.
I. The Clean Air Act's Limitations
Unfortunately, the carbon control technology options for coal-fired power plants are limited. The only options are to improve the efficiency of the plant, to switch to lower emitting fuels like natural gas, or to sequester the carbon underground (which involves separating the carbon from the exhaust stream and piping it to underground storage reservoirs, sometimes hundreds of miles away). 6 There are no add-on scrubbers that remove carbon dioxide during the process like there are with other pollutants.
The Clean Air Act allows the EPA to set two different types of technology standards. First, EPA can set blanket emission standards, called new source performance standards (NSPS), which uniformly apply to all sources covered by them. 7 EPA has set more than eighty of these uniform technology standards for various categories of sources since the Act was adopted in 1970 – covering everything from landfills and petroleum refineries to dry cleaners. 8 It set the first NSPS for power plants in 1971, and has revised those standards various times. But the current NSPS for power plants only regulates conventional pollutants, such as particulate matter, nitrogen oxides (NOx) and sulfur dioxide (SO2). 9 CO2 is not regulated.
The second general type of technology standard that the EPA can impose is done on a case-by-case (or power plant by power plant) basis. These case-by-case technology standards, called best available control technology (BACT) determinations, are conducted when a company obtains a construction permit to build a new plant or to significantly modify an existing one. 10 BACT determinations are set for each pollutant “subject to regulation” under the Clean Air Act, which includes all of the conventional pollutants regulated by the NSPS and others. 11 In 2011, the EPA began requiring new and significantly modified power plants to conduct BACT determinations for CO2. 12 Every new or modified plant subject to BACT has a slightly different limit to meet, based on the specific layout of the plant and what control technologies are available for that plant.
Now here’s the rub: according to the Clean Air Act, the case-by-case BACT standards must be more stringent than the blanket, uniform NSPS ones. The definition of “best available control technology” in the Act specifically states that “[i]n no event shall application of ‘best available control technology’ result in emissions of any pollutants which will exceed the emissions allowed by any applicable standard established pursuant to [the NSPS] section of this title.” 13 In other words, as the D.C. Circuit Court of Appeals has said, “[a]t a minimum, . . . BACT [is] as restrictive as NSPS.” 14
This requirement is important because President Obama’s plan calls for the EPA to issue the NSPS standards for new and existing power plants. Yet the EPA has already approved the more stringent case-by-case BACT standards for a number of existing and planned coal-fired power plants, and they have not amounted to much, generally requiring modest efficiency improvements that are relatively inexpensive and achieve at most about a five percent reduction in emissions. 15
For example, a case-by-case BACT standard for CO2 was set for the Wolverine Power Supply Cooperative, Inc.’s proposed 600 MW coal fired plant located in Rogers City, Michigan in 2011 and led to only a 4.7% CO2 emissions reduction. A BACT standard for CO2 was also set in 2011 for the existing coal-fired George Neal South Power Plant in Salix, Iowa, and it resulted in only about a 1.2% reduction in emissions. 16 These BACT determinations are representative of the various determinations set to date, and the plants are typical of coal-fired power plants in the industry.
While the statutory language unequivocally provides that BACT limits must be more stringent than the NSPS, the EPA might argue that the converse is not also true, and that the agency can set NSPS standards that are more stringent than previous BACT determinations. But this argument seems tenuous. The technology tests under the Act are the same in all material respects for the NSPS and BACT. So, even if the courts agree that the Act does not bar the EPA from adopting NSPS that are more stringent than previous BACT determinations, they would almost certainly find that the EPA was arbitrary and capricious if the agency set an NSPS at a significantly more stringent level than past BACT determinations that were recently set for the exact same types of sources. 17
The President’s plan directs the EPA to issue CO2 standards for existing power plants by 2015 and for new plants as expeditiously as possible. 18 In April of 2012, well before the release of the President’s climate plan, the EPA issued its first proposal to regulate CO2 from new power plants using the NSPS program. 19 That proposal determined, rather counter-intuitively, that the best control technology available for new coal-fired power plants was to be a natural gas-fired power plant, and set the standard based on a typical natural gas-fired plant’s emissions. 20 In other words, the proposal - if finalized - would essentially ban the future construction of all coal-fired power plants in this country because no conventional coal-fired plants can meet the standard. Not surprisingly, the utility industry and coal companies went ballistic with public comments (the EPA received more than 2.6 million comments) – many arguing that the EPA’s approach was unlawful. 21
The primary legal problems with the EPA’s approach are fairly obvious. A natural gas plant is not a carbon control technology; it’s a different kind of power plant. And courts (and even the EPA) have said for years that technology-based limits should not “redefine the source,” which is exactly what the EPA’s proposal would do. 22 Moreover, the EPA’s proposal would impose an NSPS limit for new power plants that is vastly more stringent than any of the existing BACT standards for coal-fired power plants.
The overwhelming industry response and these legal issues led the EPA to recently announce plans to re-issue the proposal in late September of this year, and separate the control technology determination for plants that burn coal as compared to those burning natural gas. 23 But even if the EPA does separate coal plants from gas plants in the new proposal, the control technology options for coal-fired power plants are still limited, and the EPA is hampered by past precedent. Technology-based limits cannot require a plant to switch from coal to natural gas, 24 and the EPA in its April 2012 proposal has already basically admitted that separating and sequestering the carbon is too costly, noting that it “would add around 80 percent to the cost of electricity” for a new plant. 25 All of the previously mentioned BACT decisions considered and eliminated both fuel switching and sequestration as the technological choice. That just leaves the EPA with efficiency improvements in new plant design, which would at best lead to minor emissions reductions—if new plants are built that replace older, higher emitting ones.
Yet even the EPA does not expect new coal-fired power plants to be built any time soon. The EPA admitted in its original NSPS proposal that current market conditions make it highly unlikely that anyone will build a new coal plant between now and 2020, regardless of what the EPA does with the CO2 NSPS. 26 Natural gas prices are too low and are forecasted by the EPA to stay that way, while other EPA regulations aimed at mercury and SO2 emissions are pushing the cost of new coal-fired power plants up compared to gas plants. In fact, even though the EPA’s proposal would basically ban the construction of new coal-fired power plants, the agency admitted in its proposal that it “believes that this proposed rule is not likely to produce changes in emissions of greenhouse gases or other pollutants” because of market conditions. 27
Given these current market conditions and the looming legal battles, some in the industry believe the EPA will back down from its proposal and allow the construction of new coal plants, as long as they include the most efficient design (a “supercritical” advanced coal plant). 28 This would allow the EPA to avoid setting bad legal precedent on the new NSPS, which could impact the viability of its plans for the existing power plant NSPS.
The EPA’s own statements in the past also pose an obstacle to proposing more stringent standards for existing power plants. The agency has already publicly taken a narrow view of the technological alternatives available to it in imposing CO2 standards for existing sources. In 2008, the agency admitted that these standards would likely focus on incremental improvements in the heat rates of existing units through options that “are well known in the industry” (aka energy efficiency improvements). 29 Plus in its already released proposal for new plants, the EPA made the same admission, saying that “[t]he most likely candidates for control actions [for modified existing sources] would be efficiency measures.” 30
Section 111(d) states that the EPA can force the states to adopt standards for “any existing source for any air pollutant: . . . which is not . . . emitted from a source category which is regulated under section [112] of the Act . . .” 31 Based on a plain reading, this section seems to only allow the EPA to issue existing source NSPS for categories of sources that are not subject to hazardous air pollutant standards under Section 112 of the Act. Power plants are a category of sources, however, that are subject to hazardous air pollutant standards for mercury under Section 112. 32 As such, it is highly questionable whether the EPA can even regulate existing power plants at all using Section 111(d). 33
The EPA’s regulation of CO2 from new and existing power plants under the NSPS program faces significant legal hurdles. The EPA’s best hope for the regulations to make it through the courts is if the agency takes a conservative approach and sets the NSPS for new and existing sources based on something less than the existing BACT standards. This means - at best - reductions in the range of 1-5% by 2020 for existing sources, with no emission reductions from new sources (since none are likely to be built).
The President’s climate plan calls for a 17% reduction in total nationwide emissions by 2020. Given no emission reductions are expected from the new power plant NSPS - and assuming minimal reductions from the existing power plant NSPS – the Administration will need to obtain significantly more reductions from the sources comprising the other two-thirds of national emissions, or the President’s 17% total reduction goal by 2020 will not be met.
