Perennial manages the permitting process and ensures compliance on projects of all scopes and sizes. Our staff routinely conducts field surveys and negotiates permits with federal and state agencies. Our proven area of expertise is providing support on large, complex oil and gas projects, including those under the jurisdiction of the Federal Energy Regulatory Commission (FERC).

We focus on identifying project-specific environmental topics and resources that require analysis for the permitting process. We often serve as a liaison between our clients and agencies to identify and minimize environmental impacts while maintaining project scopes and schedules. With extensive experience working with interdisciplinary project teams and agencies, we are capable of performing all necessary agency coordination and public involvement activities.
