Lead can cause neurological damage to young children and developing fetuses. The only really safe level is zero. Because poor children are the most likely to be exposed to this hazard, this is also a major environmental justice issue. The Trump EPA took the position that it could set a hazard level higher than zero because of the cost of reaching a lower threshold. In a split decision, the Ninth Circuit reversed. The statutory issues are complicated, and a dissent raised some reasonable arguments. Ultimately, though, it's hard to believe Congress wanted EPA to misrepresent that a certain level of lead is safe for children when it really isn't.

In its closing days, the Trump administration issued a rule designed to tilt EPA's cost-benefit analysis of air pollution regulations in favor of industry. Recently, the agency rescinded the rule. The rescission was no surprise, given that the criticisms of the Trump rule by economists as well as environmentalists. EPA's explanation for the rescission was illuminating, however. It sheds some important light on how the agency views the role of cost-benefit analysis in its decisions.

In the latest episode of Connect the Dots Season 5, host Rob Verchick and his guests discuss the fiscal complexities and possibilities of a just, equitable transition to clean, renewable energy. When it comes to innovation and clean energy, there’s a wide range of players building new technology and sourcing terrains to scale renewables as wide as the great unknown. Funding for those projects comes from a host of financiers, from banks to private equity firms to, perhaps, everyday consumers. The drive behind financing the energy transition results from a dedicated consortium of political agendas, business prerogatives, and consumer demand.

Dirty, polluted stormwater that runs off of industrial sites when it rains is a major cause of pollution to Maryland’s streams and rivers, and ultimately to the Chesapeake Bay. Maryland is home to thousands of such industrial sites, all of which are required by law to obtain a stormwater discharge permit from the Maryland Department of the Environment (MDE) to prevent pollution and protect public and environmental health. Unfortunately, many of these sites do not have a permit. For example, our research in one small area of Anne Arundel County found that only four out of 12 industrial sites possessed a current permit. Of the industrial sites that hold a permit, many are not in compliance with the permit requirements. Between 2017 and 2020, MDE conducted just under 2,000 inspections of permitted sites throughout Maryland and found that more than two-thirds (68%) were violating the terms of their permits. These industrial sites are commonly clustered in urban areas, creating pollution hot spots of runoff that can include heavy metals and other toxins. Such polluted waters threaten the health of those who live nearby, who are more likely to be low income and populated by people of color.

Chlorpyrifos is one of the most widely used pesticides in America, although it has been banned in the European Union. Last week, the Ninth Circuit took the extraordinary step of ordering the U.S. Environmental Protection Agency (EPA) point-blank to ban or reduce traces of chlorpyrifos in food. A dissenter accused the majority of misreading the statute in question and abusing its discretion by limiting EPA's options so drastically and giving it only 60 days to act. Warning: The majority and dissenting opinions cover 116 pages, so I'll necessarily be leaving out a lot of details and nuances.

Companies using fossil fuels like oil, natural gas, and coal are facing heavy pressure to reduce their carbon footprint. If they don’t, they could get hit with financial penalties or be completely shut down. In response, these corporations have come up with a treatment of sorts -- it’s called carbon capture and sequestration, or CCS. The idea is that the industry can continue operating as it always has, but as a caveat, it will install a system to strip carbon from emissions. The carbon will be funneled through pipelines deep into the ground, where it will be buried forever. As a result, plants can keep running, businesses rally on as usual, there’s less pollution in the air, everyone wins. Right? Not exactly. As Connect the Dots host Rob Verchick and his guests discuss in this episode, CCS is not nearly comprehensive enough to reduce emissions at a level and rate necessary to make a difference.

By the time the environmental justice movement began taking shape in the 1980s, communities of color had already been suffering from the disproportionate burdens of pollution for decades. Since then, evidence of racially discriminatory patterns in the distribution of environmental harms has only continued to mount.

A week after taking office, President Joe Biden issued an executive order “on tackling the climate crisis” that aims to face the challenge comprehensively and equitably. Biden has quickly appointed and seen confirmed a team of leaders who are committed to all aspects of this mission. Our country is finally on the cusp of meaningful climate action. The climate action train is so popular that even fossil fuel companies, which have historically sought to derail it, are now saying they’re on board. We should, of course, welcome all sincere collaborators; the fossil fuel industry is not among them.

As Maryland heads into the final stretch of a collective effort to clean up the Chesapeake Bay, it has inexplicably passed over its best opportunity in years to modernize regulation of industrial stormwater -- rain and snow that collects toxic pollution as it runs off factories, warehouses, scrap metal dealers, and other industrial sites. Earlier this year, Maryland released a proposed revision of its general water pollution permit, which limits the type and amount of pollutants that facilities can discharge into public waters and sets monitoring and reporting requirements to protect public and environmental health. Unfortunately, the state missed an important opportunity to bring stormwater regulation from the last century into the present -- but it’s not too late to change course.
