For the last century, the Supreme Court has tried to operationalize the idea that a government regulation can be so burdensome that it amounts to a seizure of property. In the process, it has created a house of mirrors, a maze in which nothing is as it seems. Rules that appear crisp and clear turn out to be mushy and murky. Judicial rulings that seem to expand the rights of property owners turn out to undermine those rights. The Court's decision last week in Cedar Point Nursery v. Hassid illustrates both points.

In addition to cleaning up our environment, the U.S. Environmental Protection Agency (EPA) must also clean up the mess the Trump administration left behind. The Biden EPA recently took an important step in this direction by finalizing its plan to rescind a Trump-era rule that would drastically overhaul how it analyzes the rules it develops to implement the Clean Air Act. If implemented, Trump's "benefits-busting" rule would have sabotaged the effective and timely implementation of this popular and essential law, which protects the public from dangerous pollution that worsens asthma and causes other diseases. On June 9, the EPA held a public hearing to gather feedback on rescinding the rule. CPR Member Scholars Rebecca Bratspies and Amy Sinden joined me in testifying in support.

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 Recently, the agency rescinded the rule.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.

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.

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.

April 30 marks President Biden's first 100 days in office. He's appointed a great climate team and is negotiating an infrastructure bill that focuses on climate change. With luck, those actions will produce major environmental gains down the road. There are also some solid gains in the form of actions that have already come to fruition. Here's where things stand.

In 2020, the world banded together to fight the COVID-19 pandemic. Now, in 2021, the world continues to change, and we seem to be progressing forward. In turn, the spotlight shifts to another great calamity: climate change. The environmental crisis has made headlines with the Biden administration making climate mitigation and renewable energy top priorities. Scientists and engineers are hard at work creating energy systems that run efficiently, withstand various constraints, and won’t pollute the air. However, as this episode of CPR's Connect the Dots podcast explains, it's also important to look at how we implement these new innovations in a way that’s equitable and purposeful to all.

Since President Joe Biden assumed office, environmental justice has been at the front and center of his administration. One key initiative: developing better mapping tools to identify communities that may bear a disproportionate burden of toxic pollution and climate change impacts. Biden’s environmental justice (EJ) plan emphasizes the value of these tools and the need to improve them.

At midnight on April 13, Maryland’s 2021 legislative session closed out with the passage of House Bill 1069 that will provide meaningful drinking water protections for tenants who rely on well water.
