Perennial Environmental Services, LLC services

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.

Federal permitting services include field surveys and the preparation and submittal of complete federal application packages. Perennial has extensive experience working with federal agencies to prepare detailed Environmental Assessments (EA) and Environmental Impacts Statements (EIS) for project-specific impacts on environmental resources and development of alternative analyses.

Ecological resources include fish and wildlife populations, habitats, and their relationships to each other, the environment, and specific ecosystems.  Perennial specializes in identifying, assessing, and evaluating ecological resources.

Perennial’s experience with wetland delineations ranges from small developments to large transportation and utility projects. Delineations are performed through an evaluation of vegetation, soils and hydrology according to the methodology prescribed by the U.S. Army Corps of Engineers (USACE) and/or state environmental agencies.  Through the use of GPS units, we collect data along wetland boundaries during field surveys allowing us to efficiently produce accurate mapping and impact calculations.

Ecological risk assessments evaluate the adverse effect to ecological and human receptors from exposure to hazards or one or more stressors.  Perennial performs assessments that provide the critical elements needed to determine the appropriate approaches to select a course of action. These assessments have a flexible process for organizing and analyzing data, information, assumptions, and uncertainties to evaluate the likelihood of adverse ecological effects. We perform well thought out contaminant and ecological receptor research to prepare ecological risk assessments with the utmost quality so our clients can implement the best course of action based on state and federal objectives.
