The Alabama Department of Environmental Management has welcomed two new members to the Alabama Environmental Management Commission recently appointed by Governor Kay Ivey.
Attorney David Carroll and geologist Stephen P. “Steve” Castleman were appointed to the commission Friday, with their terms taking effect October 1. They replace attorney H. Lanier Brown II and geologist John “Jay” H. Masingill III, whose terms are expiring. Brown has served on the commission since 2009 and Masingill since 2020.
The seven-member commission develops the state’s environmental policy, hears administrative appeals of permits, administrative orders and variances issued by the department, adopts environmental regulations and selects the ADEM director. Members also advise the director on environmental matters.
Commission members are appointed by the governor to six-year terms and are subject to confirmation by the Alabama Senate.
“ADEM welcomes the two newest members to the commission, and we look forward to working with them as we continue our work to safeguard Alabama’s environment and serve the people of this state,” ADEM Director Edward Poolos said. “We also thank Commissioners Brown and Masingill for their years of dedicated service on the commission and their conscientious work guiding environmental policy in the state.”
Carroll retired from Hunt Refining Company in Tuscaloosa, where he served as senior vice president, secretary and general counsel. In that role, he led the company’s legal, regulatory and compliance functions.
He graduated from the University of Alabama and the University of Alabama School of Law. He has more than four decades of experience in energy, regulatory compliance and corporate governance, with expertise in commercial law, environmental regulation and complex litigation.
Carroll has served on numerous boards, committees and other organizations during his career.
Castleman graduated from the University of Mississippi with a bachelor’s degree in geology and pursued graduate studies in geology at Auburn University. He is the founder and co-owner of Spectrum Environmental Inc. in Alabaster, which employs 100 people.
His experience includes strategic planning, permitting and compliance, project management and expert witness support. He has served on several state and local boards supporting the environmental profession and the continued development of professionals working in the field.
Castleman is a past chair of the Alabama Board of Licensure for Professional Geologists.
