Kazmarek Mowrey Cloud Laseter LLP (KMCL) is a top-tier environmental law firm serving public and private entities nationwide from offices in Atlanta, Birmingham, and Pittsburgh.  With seventeen highly credentialed lawyers dedicated to environmental law, we bring depth and decades of experience to address the needs of Fortune 500 companies, mid-sized businesses and industries, utilities, and state and local governments.

KMCL is a recognized source of compliance, litigation, and transactional expertise focused on the complex and evolving impact of environmental law on business.

Furthermore, we are among the East’s largest environmental practices, including those at the largest law firms focusing on corporate environmental law.  With that foundation, we provide unparalleled sophistication, expertise, and depth on challenging environmental issues at an unmatched value because our boutique platform enables our commitment to two core principles:

  1. Surpass the expertise and dedication found in the largest and most sophisticated law firms, and
  2. Understand our clients’ businesses in order to tailor our services in value-added ways and exceed expectations.

We routinely provide litigation, regulatory, transactional, and policy counselling to clients (a diverse range of Fortune 500 companies, utilities, mid-sized businesses and industries, and local governments) in the highest profile environmental matters, including:

  • Representing the State of Georgia in the “water wars”, i.e., ongoing, multi-jurisdictional water supply-related litigation with the United States Army Corps of Engineers, the State of Alabama, and the State of Florida.
  • Environmental counsel on matters nationwide for the leading producer of flat-rolled aluminium products and world’s largest aluminium recycler.
  • Act as national environmental counsel to several large real estate portfolio purchasers, as well as to manufacturing clients on corporate transactions, litigation, and regulatory compliance.
  • Prevailing for our clients’ primary interests before the U.S. Supreme Court in a case challenging a major component of EPA’s stationary source greenhouse gas regulatory program.
  • Challenging numerous EPA rulemakings of national importance in the U.S. Court of Appeals for the D.C. Circuit, as well as in other venues—often prevailing.
  • Counseling client on world’s largest planned carbon capture and sequestration project.

MacDonald, Illig, Jones and Britton LLP is one of the largest law firms in northwest Pennsylvania. For more than 125 years, the firm has provided sophisticated legal counsel to clients that range from business owners in Erie to international corporations abroad. MacDonald Illig handles matters in a timely and effective manner, by attorneys that understand business, are sensitive to the market and have the depth of resources necessary to succeed.

The firm's clients are Fortune 100 corporations, small and mid-size businesses, and individuals. MacDonald Illig has established powerful practices for solving and resolving transactional and litigation matters, including employment and labor, tax, real estate, environmental, and intellectual property law. Many firm clients turn to us for personal legal services, including trusts and estates, real estate, immigration, personal injury and family law.

Backgrounds in industries including health care, banking and insurance combined with the ability to navigate through municipal and government channels, puts the firm and its clients in the best position to succeed. It is that ability to identify the underlying issue, provide practical advice and serve as a trusted counselor that has allowed the firm to establish long-term relationships that have lasted for generations.

With offices directly across from the Bayfront Convention Center and Lake Erie on 100 State Street, the firm and its more than 45 attorneys are easily accessible to our local clients. At the same time, the firm's downtown Erie location makes it easy to handle matters throughout the tri-state area. Whether you are in Ohio, New York or across the border in Canada, MacDonald Illig can provide the depth of service and experience without the overhead and expense often associated with firms in Cleveland, Buffalo, Pittsburgh and Toronto. The location also allows our attorneys easy travel routes to clients throughout the U.S. and abroad.

As solid corporate citizens, MacDonald Illig and its attorneys contribute heavily to Erie's legal, civic and charitable organizations. It is that mutual sense of commitment between community and the firm that allows it to continue to grow after more than 125 years in business.

In changing times, MacDonald Illig continues to work with clients that seek creative means to a positive resolution. Whether the use of alternative dispute resolution makes a corporate or domestic matter more effective and efficient than litigation, alternative fee structures make more sense, or simply through the use of improved technologies, the firm understands the pressures and expectations of our clients.

We look forward to having the opportunity to serve your legal needs. Please feel free to contact our attorneys or staff for additional information.
