Our Practice


Summit Law Group represents customers in a wide variety of environmental and land use matters. We have extensive experience providing corporate, regulatory, and litigation advice in these complex, ever-evolving areas. Our customers range from closely held companies to large corporations. We also represent public-sector clients, including public ports, municipalities, and non-profits.

Summit’s environmental and land use attorneys can lead you through the maze of federal, state, and local environmental laws, rules, and guidance; we know the alphabet soup of environmental acronyms. We have particularly deep experience in contaminated site investigation and remediation, contribution actions, solid and hazardous waste regulation, natural resource damage assessments, industrial and municipal wastewater discharge permits, wetlands regulation, water rights law, real estate (including environmental due diligence), zoning and permitting for development, environmental documentation, and related areas. We also offer unique expertise in environmental law where the interests of Indian tribes are at stake, and we regularly provide advice on environmental and property issues for sites located within Indian reservations.

Our attorneys have been actively involved at a majority of the major Superfund sites in the Pacific Northwest. Summit enjoys a nationwide reputation for environmental expertise, particularly as trial attorneys and litigators. We have represented our environmental customers in numerous U.S. District Courts and in federal and state appellate courts. Summit attorneys are also on the cutting edge of climate change policy and carbon capture and sequestration.

Our customers – whether they are in the solid waste, oil, mining, timber, environmental consulting, commercial development, or manufacturing – all receive the benefit of regulatory and litigation lawyers with a special knowledge of and zeal for the business of law. We are committed to results-oriented representation.
