Empire State Adopts MCL for 1, 4-Dioxane, PFOA, and PFOS

On July 30, 2020, New York’s Public Health and Health Planning Council voted in support of maximum contaminant levels (MCLs) for PFOA and PFOS—the two most well-known per- and polyfluoroalkyl substances (PFAS). The Council voted to set the MCLs for both chemicals at 10 parts per trillion—among the lowest levels adopted by any state, and significantly lower than the U.S. EPA’s current guidance levels of 70 ppt.

Another chemical—1, 4-Dioxane—also has an MCL of 1 part per billion now. New York announced that this regulation …

How Many Have Seen Schrödinger’s Cat?: D.C. Circuit Strikes Down FERC’s Longstanding Use of Tolling Orders in Response to Rehearing Requests

In Allegheny Defense Project, et al. v. FERC (Allegheny), the U.S. Court of Appeals for the D.C. Circuit, sitting en banc, ruled last week that the Federal Energy Regulatory Commission (FERC or Commission) could not delay reconsideration of its approval of gas infrastructure projects for the purpose of postponing judicial review. In essence, in a 10-1 decision, the court said FERC’s “tolling policy”—something used in every gas pipeline case (39 to be exact) of the last 12 years—violates the strictures of the …

Long Island Water Districts’ 1,4-Dioxane Lawsuits Survive Motion to Dismiss

In March 2019, we posted about the strategy behind the Long Island water districts’ 1,4-dioxane litigations against major manufacturers—and then in October 2019, we followed that post with another report on the increasing number of those suits , which became the subject of a 12(b)(6) motion to dismiss. These suits filed by public water suppliers seek to recover costs against major manufacturers and promoters of the chemical for the design, construction, installation, operation, and maintenance of water treatment facilities and equipment required to remove …

COVID-19 and Drinking Water: An Update Amid Further Scrutiny

As the nation continues to navigate its way through the Coronavirus Disease (COVID-19) pandemic, we wanted to pass along some updated information from the Centers for Disease Control and Prevention (CDC) and the U.S. Environmental Protection Agency (U.S. EPA). Our blog post from March 19, 2020, remains a good primer on COVID-19 and drinking water, but there are a few updates to provide amid what appears to be an uptick in speculation about the transmission of the virus in sewage.

Two researchers at the …

U.S. EPA Takes Key Step Toward Regulating PFOA and PFOS

As the virus pandemic has consumed our daily news, even some of the most important developments in the environmental world seem to have floated under the radar. Last month, the U.S. Environmental Protection Agency (EPA) issued an initial regulatory determination under the Safe Drinking Water Act (SDWA) for perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA)—the two most notorious substances in the family of thousands of similar “forever chemicals” also collectively referred to as PFAS. 

The EPA’s announcement—a little over a year following its release of …

COVID-19 and the U.S. Drinking Water Supply: What We Know Now

As the nation grapples with COVID-19, we wanted to pass along information from the Centers for Disease Control and Prevention (CDC) and the United States Environmental Protection Agency (EPA) that may not be relayed as frequently as other critical details and advice on prevention and awareness.

Presently, the CDC states that COVID-19 has not been detected in drinking water, and that conventional water treatment methods that use filtration and disinfection (like those found in most municipal drinking water systems) should be effective in removing or …

When Too Much Is Too Much: EPA Declines Further Regulation Over Chemical Manufacturers

The Environmental Protection Agency (EPA) Administrator, Andrew Wheeler, signed a proposed rule under Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) to not impose financial responsibility requirements for facilities in the chemical manufacturing industry on Feb. 10, 2020. A number of environmental advocacy groups spurred this action in August 2014 when they filed a writ of mandamus in the U.S. Court of Appeals for the District of Columbia Circuit, seeking financial responsibility rules in this industry and others.

Section 108(b) of CERCLA addresses the promulgation …

Principles of Interpretation and Separation of Powers: Federal Court’s PFAS Ruling a Short Study in Both

Our readers are well aware of the ongoing debate on whether perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) (commonly known, together, as PFAS) should be designated as hazardous substances. Despite the constant attention these compounds receive, they are yet to be designated. There is a recent case out of the U.S. District Court for the Eastern District of Pennsylvania that highlights the legal significance while employing some basic principles. 

In Giovanni, et al. v. United States Dep’t of the Navy, individual plaintiffs discovered that PFAS chemicals from nearby Navy facilities had infiltrated …

An Exercise in Separation of Powers: Second Circuit Signals Affirmance of Dismissal of NYC Climate Change Lawsuit

“Global warming and solutions thereto must be addressed by the two other branches of government,” said district court judge John Keenan last July in nixing New York City’s climate change nuisance suit that seeks to hold major oil companies liable for global-warming related injuries resulting from greenhouse gas emissions. New York City appealed Judge Keenan’s dismissal to the second circuit, arguing that its action is not an attempt to regulate emissions.

Late last week, hearing New York City’s appeal of Judge Keenan’s dismissal, the second …

Early Halloween Scares: Defendants File Motion To Dismiss In 20 Long Island 1,4-Dioxane Litigations

Earlier this year, Environmental Law Monitor  posted about 1,4-dioxane litigations filed in the U.S. District Court for the Eastern District of New York. These litigations followed on the heels of the Suffolk County Water Authority’s (SCWA) 2017 watershed action concerning drinking water contamination. Almost two years removed from the SCWA action, it appears that at least 27 Long Island water districts have filed actions (with three new filings this month), mostly following in line with the litigation strategy developed by SCWA. If you recall, …
