Carroll 'Mack' McGuffey III

Practice Areas

Mack McGuffey focuses his practice on the Clean Air Act and helps clients obtain needed permits, solve compliance challenges, participate in rule and policy making activities, and minimize enforcement risk by bridging the gap often found between technical realities and legal requirements. Mack has focused almost exclusively on air law since starting his practice in 2003. Since that time, he has represented electric utility, landfill, manufacturing, and other industrial clients in connection with important air quality issues arising out of federal and state regulations governing the construction and operation of stationary sources of air emissions. Mack also has extensive experience in litigation over air regulations and has represented his clients’ interests in many of the most significant air law cases over the last decade, including successful challenges to the New Source Review Tailoring Rule, the Mercury and Air Toxics Standards, and the Clean Power Plan.
