Environmental Compliance and Counseling

Clients frequently turn to Arnold & Porter when their most difficult, novel, or costly regulatory questions confront them. We assess advice on challenging regulatory questions, negotiate and obtain environmental permits and approvals for complex development projects, and identify and manage product supply chain issues. We also assist clients in developing and implementing company compliance programs and management systems, including "self-audits" and other types of internal reviews. Our attorneys are experienced and adept at teaming with in-house staff, often serving in an advisory capacity to resolve questions not previously faced by the client. Across the full spectrum of environmental fields — air quality and climate change, infrastructure and permitting, natural resources, land use, chemicals, and more — we combine our legal know-how and experience as former senior government agency officials with an integrated problem-solving approach to address our clients' most complex regulatory challenges.

  • Unparalleled Expertise: Our attorneys have an in-depth understanding of the full scope of environmental law, including laws governing emissions and wastes (such as the Clean Air Act, the Clean Water Act, and the RCRA); contaminated sites (such as CERCLA and OPA); chemicals (such as TSCA and FIFRA); infrastructure and permitting (such as NEPA and ESA); and similar state laws.

  • Comprehensive and Creative Strategies: Clients seek out our attorneys for innovative approaches to solve complex environmental issues such as site remediation; compliance counseling; advocacy related to proposed rulemakings, climate change, and sustainability; crisis management; and all aspects of corporate and real estate transactions, including due diligence and environmental liability transfers.

  • Extensive Government Experience: Many of our partners have served in distinguished roles in federal or state government, including the Environmental Protection Agency and the U.S. Department of Justice. We understand how government works and we have the credibility and reputation for integrity to effectively advocate on behalf of our clients.
