Originally published on Legal Planet. When a facility installs and operates the required pollution control equipment, we normally think of the pollution problem as solved. But there still may be bursts of pollution associated with start-up, shut-down, accidents, or external events. A recent study of pollution in Texas shows that these events have substantial health […]

Originally published on Legal Planet. The Trump administration's hostile attitude toward science has continued unabated. The administration has used a triad of strategies: efforts to defund research, suppression of scientific findings, and embrace of fringe science. Budget. The administration continues to favor deep cuts in research support. Its initial 2020 budget proposal calls for a 13 […]

According to press reports, EPA is preparing to ignore possible deaths caused by concentrations of pollutants occurring below the national ambient air quality standards (NAAQS). This is a key issue in a lot of decisions about pollution reduction. For instance, there is no NAAQS for mercury, but pollution controls on mercury would, as a side benefit, […]

Originally published on Legal Planet. To do its part in keeping climate change to tolerable levels, the United States needs to cut its carbon emissions at least 80 percent below 1990 levels by 2050. That’s not just a matter of decarbonizing the electricity sector; it means changes in everything from aviation to steel manufacture, and reducing not […]

Climate change has already had serious effects, but as we know from the steady and increasingly loud drumbeat of projections from various scientific bodies, the dangers will grow much greater in future decades. But what does this actually […]

Originally published on Legal Planet. Every day seems to bring more news of the Trump administration's dogged efforts to reduce environmental protections and accelerate climate change with increased carbon emissions. But, as has been true since Trump took office, the picture at the state level is much different. State governments across the country have accelerated […]

Originally published on Legal Planet. Every day, it seems that there is a headline about some investigation involving campaign finance violations, the White House, or the actions of some foreign power. Perhaps that's all the bandwidth that Congress has. But there are other areas calling out for inquiry. Here are just a few: CAFE Standards. […]

Originally published on Legal Planet. Cost-benefit analysis has long been the target of environmentalist ire. But one lesson of the Trump years has been that economic analysis can be a source of support for environmental policy — it is the anti-regulatory forces who have to fudge the numbers to justify their actions. Most energy and […]

Originally published on Legal Planet. EPA pollution regulations are based on an assessment of the risks posed by pollutants. This can be a complex scientific judgment. The Clean Air Scientific Advisory Committee (CASAC), the agency's scientific advisory board, is pushing for major changes in the way that EPA approaches this analysis. The effect would be […]
