Greg Patten

Greg has more than three decades of experience in the environmental field. During emergency spill-response and enforcement actions, clients look to Greg not only for regulatory guidance and support, but also for practical solutions and strategies for managing response actions. His regular work includes leading environmental audits, performing due-diligence reviews, preparing environmental plans and permits, developing environmental management systems, providing compliance training, and helping clients understand the application of regulations to specific operations and activities.

Before he joined Barr, Greg served as a 24-hour spill response, remediation, and disposal contractor. That practical experience, combined with a broad knowledge of state and federal environmental regulations, makes him a unique resource when resolving complex compliance issues and enforcement actions.
