Environmental Regulations
Key stakeholders are focused on environmental risks and opportunities like never before. That’s why we serve as strategic partners looking beyond day-to-day issues to anticipate and navigate evolving trends, politics, and agendas – always with your long-term goals in mind. From business-critical operations and compliance to defending novel or aggressive litigation and enforcement actions, we find pathways to advance commercial objectives while balancing and mitigating risk.
The federal, state and local environmental rules that impact your business span chemical substances, air, water, solid and hazardous waste, pesticides, community right-to-know, and myriad other areas. We can help you identify where regulations intersect with your operations and craft proactive, sustainable strategies to mitigate litigation and enforcement risk. And to keep you ahead of the curve on emerging issues, we have developed unique, multi-disciplinary Task Forces to track, anticipate, and advise on cutting-edge issues related to PFAS and emerging contaminants, plastics, environmental justice, ESG, and State AG Enforcement trends.
“The environmental practice is excellent and they interact with all groups at the firm.”
Regulatory counseling
Our team has deep ties to state and federal law makers, actively monitoring laws across the globe and engaging with regulators on their implementation. We ultimately help clients shape modern federal environmental law by participating in notice-and-comment rulemakings, the resulting appellate litigation, and advocacy with the agencies.
Litigation & enforcement
When the stakes are high, our experience defending groundbreaking complex environmental litigation and enforcement actions offers peace of mind. Our seasoned environmental litigators vigorously defend actions arising under any of the federal environmental statutes, including CERCLA, RCRA, CWA, CAA, TSCA, FIFRA, and ESA as well as the state equivalents. Our team is also experienced in defending against cutting edge litigation emanating from key states like California, Maine, New York and others.
Compliance & auditing
From single-issue audits and programs to multi-media audits and programs encompassing all aspects of environmental health and safety, create and manage environmental audit and compliance programs tailored to your business.
Transactional support
Environmental issues can arise from the transfer and financing of businesses and real estate worldwide. To support your most strategic transactions, we help investors, buyers, sellers, and lenders perform environmental diligence, negotiate the allocation of environmental liabilities and advise on insurance major coverage cases and issues involving environmental liability and remediation costs.
ESG/Climate/Sustainability Counseling & Litigation
From assessment and action to accountability and reporting, we can add value to your ESG efforts wherever you may be in your ESG lifecycle. Whether you’re in the early stages of identifying ESG goals and needs or defending litigation and enforcement actions, our team can work hand-in-hand to identify where you want to be and help you get there. Our forward-looking solutions help navigate ESG issues in a way that seizes opportunities and maximizes long-term value.
