Regulatory Liaison/Public Relations

ESA represents clients before regulatory agencies, boards, panels and courts to facilitate cost-effective solutions to compliance issues.  We can also provide information services to help avoid confrontations with the public.

Expert Witness and Litigation Support

ESA has personnel with extensive industry, regulatory and consulting experience in a wide variety of disciplines to provide expert witness and litigation support.  ESA can assist with disputes arising from regulatory compliance, agency policy, and environmental contamination, or with preparation for oil and gas or other regulatory proceedings.


ESA provides research services ranging from simple database record reviews to complex historical reviews of agency regulations, policies and procedures.  We will also find, review and interpret historical aerial photographs, maps, logs and technical reports to identify potential problems and opportunities.

National Environmental Policy Act (NEPA)

ESA helps clients avoid the need for wetland permits by pre-inspecting proposed drill pad locations, pipeline corridors, or construction projects to identify locations or routes that are not jurisdictional and will not require a permit. If permits are required, ESA prepares and submits delineation reports , mitigation plans, and  a permit application, to the U.S. Army Corps of Engineers.  ESA acts as a liaison between you and regulatory officials to expedite the permitting process.

Private projects can be subject to the requirements of NEPA if they are determined to have a federal nexus which can include impacts to waters of the United States under Section 404 of the Clean Water Act; activities conducted below the Ordinary High Water Mark of navigable waters of the United States under Section 10 of the Rivers and Harbors Appropriation Act of 1899; federal land or mineral estate; or Indian land or mineral estate.


The Clean Water Act prohibits unauthorized filling of “jurisdictional waters of the United States,” but a permit can take more than a year to process.
