Last week, I discussed the Administration’s guidance concerning the exercise of its enforcement discretion during the COVID-19 pandemic. Now comes evidence that the guidance may actually be self-defeating. While the administration is – understandably – trying to cut regulated industries some slack while they are trying to deal with COVID-19, it turns out that exposure to PM2.5 has a significant impact on the COVID-19 death rate.… More

Half a Loaf May Not Be Too Bad: The 9th Circuit Affirms Most of EPA’s Approval of the San Joaquin Valley SIP
Earlier this week, the 9th Circuit Court of Appeals granted part of a petition challenging EPA’s approval of California’s SIP for ozone and PM 2.5 in the San Joaquin Valley. While the trade press has been focusing on the partial reversal, I think that EPA won much more than it lost.
What did it lose? California’s plans for complying with the ozone and PM 2.5 NAAQS relied in part on emissions reductions to be attained as a result of California’s authority under the CAA to impose more stringent mobile source emissions standards than are applicable nationally. … More
EPA Proposes Revisions to the PM 2.5 NAAQS: How Much Will It Matter?
Last Thursday, in response to a court order, EPA finally proposed revisions to the national ambient air quality standard for PM2.5. The most significant part of the rule is EPA’s proposal to lower the primary annual standard from 15 ug/m3 to a range of from 12 ug/m3 to 13 ug/m3.
At a certain level, the proposal should not really be news and should not have a significant impact. After all,… More
Traditional Pollutants Definitely Still Matter: EPA’s Draft Review Recommends More Stringent Particulate Standards
Last week, I posted about improvements in air quality since 1990. It’s a good thing air quality is improving, because, at the same time, the science keeps suggesting that ever lower pollutant levels pose risks to public health. The latest news was EPA’s draft review of the appropriate level at which to set the National Ambient Air Quality Standard for particulate matter.
EPA most recently revised the PM standard in 2006,… More
More Bush Administration Air Rules on the Way Out?
We have previously posted about EPA’s efforts to roll back regulatory changes made by the Bush Administration, particularly with respect to the NSR program. There is no question that the roll-back continues. This week, EPA announced it would review three separate NSR rules promulgated by the Bush administration. These include:
The “reasonable possibility” rule, which identified when major sources must keep records even if a contemplated change is not expected to trigger NSR review
The fugitive emissions rule,… More
So, You Liked NSR Enforcement? How about State Public Nuisance Claims?
In a decision that could have significant impact on states’ efforts to limit cross-border pollution, Judge Lacy Thornburg of the District Court for the Western District of North Carolina issued an affirmative injunction against the TVA this week, requiring it to install pollution control equipment at its facilities located nearest to North Carolina and imposing specific emissions limits from those facilities. The basis for the injunction was a finding,… More
