On January 5, EPA added 1-bromopropane (1-BP), which is also called n-propyl bromide, to the list of Hazardous Air Pollutants (HAP) under the federal Clean Air Act. 1-BP is used as a substitute for other HAPs in dry cleaning and other industries. This marks the first addition to the list since it was established as part of the 1990 Clean Air Act Amendments. The addition was prompted by petitions to list 1-BP by the Halogenated Solvents Industry Alliance and the New York State Department of Environmental Conservation.

EPA is expected to issue additional guidance and regulation under the National Emission Standards for Hazardous Air Pollutants (NESHAP) that will further govern the emission of the 1-BP; in the interim, companies that emit 1-BP need to consider how the addition of 1-BP to the list of HAPs will affect their permitting, emissions reporting, and regulatory compliance.

Recently, the U.S. Environmental Protection Agency (EPA) took a preliminary step toward requiring limits on some National Pollutant Discharge Elimination System (NPDES) discharges of per- and polyfluoroalkyl substances (PFAS) into surface water. On March 17, EPA issued an advance notice of proposed rulemaking pursuant to the Clean Water Act (CWA), which seeks public comment on data EPA has collected about certain PFAS discharges to surface water and requests additional information about businesses that make or use these substances (the ANPRM). The public has until May 17, 2021, to submit comments.

Regulated industries pay close attention to how regulators use scientific data, because the stakes are high. While scientific knowledge may evolve rapidly, regulatory processes — and the business decisions that rely on them — tend to proceed more deliberately. As a result, the regulated community has long pushed the U.S. Environmental Protection Agency (EPA) to base its decisions only on scientific information that is present in the public domain and thus subject to greater scrutiny.

While President Trump’s border security policy has dominated recent news headlines, his deregulation policy has quietly jockeyed into a better position to survive court scrutiny. Last week, a federal district court issued an opinion that suggests it may never confirm whether the Trump Administration’s “two-for-one” executive order thwarts consumer protection and safety-related rulemakings by past administrations, because no plaintiffs have standing to raise these arguments. Rulemakings have a primary role in environmental law. This decision emphasizes that, in many cases, rulemakings will continue to be primarily shaped by the executive branch, not courts, excepting in particular cases.
