“Renowned practice comprising some of the leading environmental lawyers in this field,” with “particular expertise in the energy sector” is how Chambers USA describes our environmental practice group. We have a proven track record of helping clients across the country successfully handle some of the most complicated environmental issues arising from their business operations.

Chambers reports our clients are impressed with our lawyers’ “ability to deal with complicated issues without constantly researching past precedents, because they were already intimately familiar with them.” Our experience goes beyond mere knowledge of the law. It includes working onsite with our clients at their refineries, chemical plants or manufacturing facilities, as well as negotiating with government regulators at both the state and federal levels.

Our clients range from mid-sized regional businesses to large global Fortune 50 businesses, and we have even helped state and federal agencies on high profile projects. We know how to help close deals, negotiate with government agencies and litigate for our clients. Our reputation before regulatory agencies in particular as well as the environmental community in general is based on the quality of our work, our credibility, our professional contributions to the practice of environmental law, and the caliber of the clients we represent.

Our lawyers counsel clients on regulatory requirements relating to ongoing operations, as well as those associated with the construction of new facilities and modifications of existing facilities. We monitor and provide input to pertinent agency rulemaking and policy development, as well as help clients in developing and applying environmental policies and management programs.

In transactions, we work closely with clients and their other professional advisors to devise innovative methods to streamline due diligence procedures, to identify environmental risks, including risks related to climate change, and to devise creative and cost-effective ways to manage and insure against those risks. We also assist clients on the environmental aspects of corporate disclosures made under other governmental regulatory programs, such as those of the SEC and FTC.

Our lawyers also represent clients in all types of environmental litigation, including criminal as well as civil and administrative enforcement actions, citizen enforcement actions, and administrative appeals and rulemaking.

The members of our national Environmental team include senior lawyers who have been practicing together for many years, and several are routinely recognized for their skill by Chambers USA and other publications. Of course, collaboration is key to our success. Our lawyers frequently team with client representatives, consultants, investment advisors, environmental lawyers from other jurisdictions and lawyers in other practice areas, both inside and outside Haynes and Boone.

For Hazardous Air Pollutants, “Once in, Always in,” is Out

In a major departure from over 20 years of practice, the EPA announced on January 25 that it is withdrawing the “once in, always in” (OIAI) interpretation of the hazardous air pollutants (HAPs) program. The OIAI required sources of HAPs to permanently comply with Maximum Achievable Control Technology standards applicable to major sources of HAPs, even when those sources’ emissions are below major source levels.
