Thomas Bristol

Thomas Bristol is a Principal Scientist based in South Carolina with more than 18 years of experience in environmental consulting focused in the areas of environmental regulatory compliance; ecology and natural resources, and environmental assessment. Thomas is a senior leader in Geosyntec's Natural Gas practice group.

Thomas' academic background is in biology, ecology, and environmental assessment. He applies his knowledge and technical experience to assist clients by managing and directing site feasibility studies; alternatives analyses; wetlands and habitat inventories and delineations; threatened and endangered species inventories; critical habitat assessments; cultural resources screening; and coordinating between agencies for compliance and documentation required under federal environmental regulations. Covered regulations include the Clean Water Act, Endangered Species Act, National Environmental Policy Act (NEPA), National Historic Preservation Act (NHPA), Energy Policy Act, and Natural Gas Act. A primary focus has been with Federal Energy Regulatory Commission (FERC) compliance projects for federally regulated interstate natural gas facilities.  

An experienced professional, Thomas has helped clients with complex problems within multiple disciplines including water and natural resources, environmental permitting and regulatory compliance, environmental site assessment, remediation, and environmental due diligence. He has managed multi-state and multi-site utility projects for environmental regulatory compliance. He has served as project director for natural gas transmission pipeline system evaluations for a FERC regulated natural gas pipeline company to identify and assess potential aquatic resource compliance associated with exposed pipelines and integrity management projects.  He also successfully negotiated favorable resolution agreements for the utility company with regulatory agencies and saved the company significant costs in potential compensatory actions and mitigation.

He managed and secured environmental permitting for a 150-mile, long-distance linear utility project, from Washington D.C. to Richmond, Virginia, acquiring all environmental regulatory permits for the project route including multiple federal navigable water crossings. The key component for the ultimate success of the project and fulfillment of client construction and in-service schedule was a two-mile horizontal directional drill (HDD) installation under the Potomac River between Maryland and Virginia. This crossing of a highly-regulated resource included ecologically sensitive habitats which required interagency coordination for special exemptions and negotiation of special permit conditions. Permitting for this effort required negotiation permitting with multiple regulatory within an aggressive project schedule.
