More than ever, regulatory and citizen-initiated actions regarding environmental law are demanding decisive responses and measured legal counsel. Our experienced team represents private and public clients on a broad range of environmental issues at the federal, state, and local levels. Clients include publicly traded and privately held companies, public utilities, alternative energy companies and power producers, real estate developers, banks and other lenders, manufacturers, construction companies, and municipalities.

Harnessing big power—in the environment and in the courtroom.

Our attorneys have participated in some of the Northeast’s largest and most significant environmental permitting, compliance, and litigation cases-including Deepwater Wind (the first off-shore wind project in the U.S.), the Rhode Island Attorney General’s lead paint suit, and a mass tort case involving over 3,000 plaintiffs.

We represent energy companies and utilities in project development, renewable energy matters, regulatory matters, permitting and approval, and a wide range of litigation and environmental issues. We have become leaders in the field of renewable energy. We represent several of the country’s foremost developers of wind and solar energy and counsel traditional energy distribution companies to meet renewable energy requirements.


We provide guidance in insurance coverage, including cost cap and pollution liability issues. And, have successfully litigated toxic tort, hazardous waste, and state and federal Superfund cases.

We provide representation in EPA and other regulatory enforcement actions, including:

  • Superfund
  • Clean Air Act
  • Clean Water Act
  • Brownfields (under state or federal programs)
  • Title V permit provisions
  • Community Right-to-Know Act
  • Regulatory compliance
  • Due diligence for corporate and real estate transactions

We counsel clients on environmental permitting issues, such as:

  • Securing permits related to environmental media
  • Pollutant discharges (including air emissions and programs under the Federal Clean Air Act’s new source review and the National Pollutant Discharge Elimination System)
  • Work in or near freshwater and coastal wetlands
  • Pollution control technology
  • Complex emissions calculations (e.g. opacity and odor concerns)
