NEPA Compliance and Documentation

We provide public and private clients with National Environmental Policy Act (NEPA) compliance and documentation support for a wide variety of projects ranging from utility-scale renewable energy development to local affordable housing projects. Our NEPA project managers maximize efficiency by utilizing Dudek’s in-house technical resource experts to support defensible NEPA documents done right the first time.

Tailored NEPA Compliance Strategies

We customize a NEPA strategy aligned to your unique project’s scheduling and budgetary needs. Dudek’s NEPA planners help evaluate project scopes, identify NEPA triggers, and propose efficient NEPA approval methods. When we’re involved early in project development, we help shape project scopes to minimize the risk of escalating NEPA reviews, such as from a Categorical Exclusion to Environmental Assessment (EA), or EA to Environmental Impact Statement.

During the permitting phase, our planners collaborate with the federal agency’s NEPA counterpart and project proponent to streamline the process, ensuring a sound, defensible NEPA decision. As impartial staff, we also manage reviews and offer contract services, serving as an extension of your team.

Expert Support for Navigating Environmental Challenges

We apply NEPA knowledge to ensure compliance with municipal laws, agency regulations, and national case law that may impact development in constrained areas, the urban built environment, and coastal zone, as well as energy and public infrastructure development.

Our NEPA planners creatively address regulatory challenges and constraints, while our NEPA project managers prioritize communication and agency relationships, anticipating issues to minimize risk to the project schedule and budget.
