EPA has proposed to revoke the Trump administration finding in 2020 that it is not appropriate and necessary to regulate emissions of air toxics from coal- and oil-fired electric generating units. Instead, EPA proposes to reaffirm its 2012 and 2016 determinations supporting such regulation.

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
Late last week, EPA issued a Supplemental Finding, concluding that it is still “appropriate and necessary” to regulate hazardous air pollutants from coal- and oil-fired electric generating units. The Supplemental Finding was necessary after the Supreme Court ruled earlier this year that EPA’s original decision to regulate HAP emissions from EGUs was flawed because EPA did not consider costs in making the decision. Is the Supplemental Finding enough to ensure that the Mercury and Air Toxics rule is upheld this time around? … More
D.C. Circuit Affirms EPA’s Utility Air Toxics Rule: An “Appropriate” Rule Need Not Be Justified By Cost-Benefit Analysis
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
There have been so many developments recently on the air front (and I’m so far behind due to an appellate brief) that I thought I would combine a few recent items.
First, oral arguments were heard Monday on the challenges to the Bush EPA ozone NAAQS of 0.075 ppb. As I have previously noted, the Court of Appeals for the District of Columbia Circuit has made pretty plain that EPA cannot ignore the recommendations of the Clean Air Science Advisory Committee in setting the NAAQS. … 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
Is mercury a local problem or not? For years, power plant operators have claimed that mercury deposition is really a global problem. Environmentalists have pointed to studies arguing that hot spots affected by local emissions do exist. This week, according to the Cape Cod Times, John Colman, a USGS researcher – hardly likely to be a shill for the power industry – is going to report results of a study showing that mercury accumulation in both soil samples and fish tissue are comparable in Cape Cod and the Olympic Peninsula in Washington. … More
For Coal, It’s Not All About Climate Change: Credit Suisse Predicts New Air Rules to Close 60 Gigawatts of Coal Capacity
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
While Congress may be fiddling on climate legislation, Senators Carper and Alexander are attempting to put three pollutant legislation back on the congressional agenda. Yesterday, they introduced an aggressive three pollutant bill. Here are the highlights. The bill would:
Codify the CAIR program through 2011
Gradually reduce the cap on SO2 emission allowances to 1.5 million tons by 2018 – substantially more stringent than the CAIR would have imposed.… More
As I noted a couple of weeks ago, Representative John McHugh (R-NY) has introduced legislation that would require significant reductions in emissions of SO2 and NOx, and mercury from power plants. Now, Senators Carper (D-Del.) and Alexander (R-Tenn.) have announced that they will be introducing their own three-pollutant legislation in the Senate. Since they have not yet introduced a bill, we’ll all just have to imagine the specifics for now,… More
Harking back to legislative efforts of a few years ago, Representative John McHugh (R-NY) yesterday introduced legislation that would require significant reductions in emissions of SO2 and NOx, and mercury from power plants. The highlights of the bill include the following:
- No later than two years from enactment, EPA must promulgate regulations requiring that powerplants:
- reduce SO2 emissions by 75% over the Phase II levels contained in the current CAA acid rain program
- reduce NOx emissions by 75% over 1997 levels
- Even aside from the above-described reductions,…
Coal has taken its lumps this week. Today, legislation was introduced in Congress to require EPA to promulgate MACT standards for mercury emissions from coal-fired power plants within one year of enactment of the legislation.
There has been some suggestion that the legislation was filed simply to prod EPA to drop its appeal of the decision by the D.C. Circuit Court of Appeals rejecting EPA’s Clean Air Mercury Rule (CAMR),… More
