Last week, EPA formally revised the cost-benefit analysis for its rule limiting the emissions of hazardous air pollutants from coal-fired power plants.  The rule jettisons consideration of so-called “co-benefits,” in this case, the benefits from the reduction in emissions of PM2.5 that result from limits on mercury emissions.  The very idea of excluding consideration of co-benefits is just plain incoherent.

I’ve spent my career defending cost-benefit analysis to many of my environmentalist friends. … More

Earlier this week, the D.C. Circuit Court of Appeals held that the “Wehrum Memo,” which reversed EPA’s longstanding policy of “once in, always in” regarding MACT jurisdiction, was not final agency action subject to judicial review.  Like Judge Rogers, I dissent. 

The majority makes much of its effort to clarify this “byzantine” area of the law.  My take is that,… More

Earlier this month, the D.C. Circuit Court of Appeals ruled on challenges to EPA’s National Emission Standards for Hazardous Air Pollutants from the brick and clay industries.  The Court granted the environmentalists’ petitions almost in their entirety and denied the industry petitions in their entirety.

The decision is not really surprising, because EPA had failed to justify a number of the decisions that it made. … More

Yesterday, the D.C. Circuit Court of Appeals remanded EPA’s MACT standards for PCBs, polycyclic organic matter, and hexachlorobenzene to EPA.  Rather than setting specific MACT standards for these compounds, EPA regulated them through “surrogates,” commonly particulate matter.  The Sierra Club and others argued that EPA did not adequately justify the use of surrogates.

The three-part test for the adequacy of a surrogate is clear and worth repeating:

(1) the relevant hazardous air pollutant is invariably present in the proposed surrogate;… More

On Friday, the D.C. Circuit largely upheld EPA’s Boiler MACT rule.  The industry challenges were a complete washout.  The environmental petitioners won one significant victory and a number of smaller ones.

The environmental petitioners’ one significant victory is important.  EPA included within relevant subcategories any source that burns a fuel containing at least 10% of the “subcategory-defining fuel.”  However, for defining MACT, EPA included only those sources that burn fuel containing at 90% of the subcategory-defining fuel for existing sources,… More

On Tuesday, the D.C. Circuit Court of Appeals affirmed EPA’s update of its hexavalent chromium MACT rule.  Suffice it to say that this was a little easier than review of the power plant MACT rule.

The Court rejected both industry and environmental group challenges, in what was largely a straightforward application of Chevron.  The opinion is nonetheless useful in laying out what EPA must have in the record to justify ratcheting down MACT standards.… More

Last week was hazardous air pollutant regulation week at the D.C. Circuit Court of Appeals. First, as we reported, the Court affirmed EPA’s mercury air toxics rule, determining that EPA need not take cost into account in promulgating rules for electric generating units (EGUs) under § 112(n) of the CAA. On Friday, the Court affirmed the substance of EPA’s revised hazardous air pollutant rules for cement kilns,… More

On Thursday, EPA finalized revisions to the Mercury and Air Toxics Standards, or MATS (also known as “Utility MACT”).  The most significant change was to revise the mercury emissions standard from 0.0002 pounds per gigawatt-hour to 0.003 pounds per gigawatt-hour.  The change was made in response to comments suggesting that the more stringent standard simply wasn’t attainable.  EPA notes that attainment of the 0.003 lb/GWh will still require installation of the same types of pollution control equipment.… More

Late last month, in Wildearth Guardians v. Lamar Utilities Board, Judge David Ebel ruled that Lamar violated the Clean Air Act by not obtaining a MACT determination, given that its potential emissions of hydrochloric acid were 10.3 tons per year, above the 10 tpy limit for any single hazardous air pollutant. The decision provides an abject lesson on the costs imposed by regulatory uncertainty.

The facts,… More

Yesterday, the North American Electric Reliability Corporation, or NERC, released its 2011 Long-Term Reliability Assessment. The NERC report identified environmental regulations as one “of the greatest risks” to reliability. Much of the focus of the concern was on EPA’s MACT rule for hazardous air pollutants and its 316(b) rule for cooling water intake structures. While expressing uncertainty about these not-yet finalized rules, the NERC report took an extremely cautious approach,… More

There has already been significant attention devoted to whether EPA’s “train wreck” of rules affecting coal-fired power plants would affect electric system reliability. The Congressional Research Service analysis looked at the coming rules more broadly, but did touch on reliability, noting that most of the coal plants likely to be retired as a result of EPA regulations are small and inefficient, and already run infrequently. As we noted last June,… More

As the deadline passed last week for submitting comments on EPA’s Utility MACT rule, it’s worth taking a big picture look at how the commenters line up. Big utility groups, such as the Edison Electric Institute and the American Public Power Association are looking for EPA to delay the rules. The basic argument is that it is going to take a long time to comply. EEI states that so many facilities will require extensions that the number of requests will create a backlog that will itself essentially create compliance problems.… More

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,… More

If anyone had any doubts about the significance of the conventional pollutant regulations that EPA would be rolling out, even in the absence of a full cap-and-trade program for GHG, Wednesday’s release of EPA’s revised power plant MACT proposal should go a long way towards eliminating those doubts. As most readers know, the rule replaces the Bush-era MACT rule that would have created a trading program.

The rule poses a problem for critics of EPA. While arguments can be made about the feasibility of some of the standards and the cost to comply,… More

Last March, I noted that Gina McCarthy’s belief that, in the near term, the biggest impact on GHG emissions would come from EPA’s traditional regulatory programs, rather than through GHG regulation. A report recently released by Credit Suisse indicates that she might be right. Looking at EPA’s upcoming promulgation of the Clean Air Transport Rule and the mercury MACT rule, Credit Suisse predicts that between 50 and 69 gigawatts of old coal plants will be retired between 2013 and 2017 as a result of implementation of the two rules. Credit Suisse also predicts that approximately 100 gigawatts of capacity will require significant additional investment to comply with the rules.… More
