Overview

BCLP has particular depth in the environmental field and we offer a leading environmental practice committed to balancing social, environmental and economic concerns. For more than 30 years, our lawyers have represented clients facing a broad range of environmental issues and challenges, including environmental compliance counseling, litigation, liability management, strategic planning and stewardship. The technical skills of our environmental lawyers combine with a multidisciplinary approach to offer clients an exceptional, comprehensive service. Our practice methods are deliberately solution-orientated and geared towards treating environmental law practice as a means to client’s ends rather than as an end in itself. 

The lawyers who practice environmental law at BCLP have the experience and reach to assist clients in the wide variety of matters they face in the field, in the courtroom and at the negotiating table. The hallmarks of our practice are deep technical knowledge in environmental and occupational health and safety law, a record of success in the litigation and trial of significant environmental and related insurance-coverage lawsuits (including group/class actions and mass torts), and advising on major projects of international, national and regional importance that raise complex environmental issues. We help our clients to navigate through the intricacies of environmental law and policy, including nature conservation, environmental impact assessment, environmental regulatory issues, dispute resolution and the environmental aspects of real estate and corporate transactions. Delivering solutions to environmental problems that confront owners of contaminated land, and developers of regeneration projects on brownfield land, also remains a core part of our business. 

Our lawyers are well aware that it is often essential for corporate and other institutional clients to maintain a working relationship and reputation for integrity, cooperation and environmental excellence with regulators and other public stakeholders. Our lawyers have many years of experience working with agencies and other stakeholders to represent clients effectively and with appropriate sensitivity to their reputational interests.  

Lawyers in the Environmental Practice Group represent the firm’s clients over the full spectrum of environmental and occupational safety and health matters. Please visit our associated environment pages to view more specific areas of our experience.

PFAS in firefighting foam (AFFF) and equipment: state-by-state regulations

Numerous states have either enacted or proposed regulations regarding per- or polyfluoroalkyl substances (“PFAS”) present in Class B Aqueous Film-Forming Foams (“AFFF”) used for firefighting, or PFAS present in firefighters’ clothing and equipment.  This alert provides a comprehensive state snapshot regarding the status of these regulations across the United States, especially as significant portion of the federal activity involved with firefighting foam involves products used by the Department of Defense (“DOD”). These regulations typically involve restrictions in four general areas:  Discharge or Use Restrictions.  These regulations usually limit or prohibit the use of AFFF in training or testing exercises, and may only allow the use of AFFF in active firefighting situations; Disposal, Storage, Inventory or “Take-back” Provisions.  Some states have enacted state-run programs to purchase and dispose of AFFF, usually purchasing supplies from government agencies; Notification or Reporting Requirements.  When continued use of AFFF is allowed, some states have required that businesses report specific details regarding their discharge; and Limitations on Personal Protective Equipment (“PPE”).  Some states have limited or prohibited PPE for firefighters that contain PFAS compounds.

PFAS in groundwater: state-by-state regulations

In the absence of federal cleanup standards for per- and polyfluoroalkyl substances (“PFAS”) in groundwater, several states have started the process of regulating PFAS in groundwater themselves. As a result, states have adopted a patchwork of regulations and guidance standards that present significant compliance challenges to impacted industries. This client alert explores the current landscape of state regulations regarding the advisory, notification, and cleanup levels for PFAS – typically perfluorooctane sulfonic acid (“PFOS”) and perfluorooctanoic acid (”PFOA”) – in groundwater.
