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

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

The general rule under the Clean Air Act is that any:

person may bring suit in district court against the EPA Administrator for an alleged failure to perform a nondiscretionary act or duty, and the district court has jurisdiction “to order the Administrator to perform such act or duty,” as well as to “compel . . . agency action unreasonably delayed.” By contrast, “judicial review of final action by the EPA Administrator rests exclusively in the appellate courts.… 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

Yesterday, the D.C. Circuit Court of Appeals affirmed EPA’s rule setting limits for emissions of mercury and other air toxics from fossil-fuel-fired electric steam generating units.  The focus of the decision – and the issue on which Judge Kavanaugh dissented – was whether EPA was required to consider the costs that would be imposed by the rule.  EPA said no and the majority agreed.

Section 112(n) of the Clean Air Act required EPA to perform a study of the health hazards related to hazardous emissions from EGUs prior to regulating them. … More
