Stell staff members have supported over 200 National Environmental Policy Act (NEPA)-type environmental studies for federal, state, and municipal agencies. The studies have included environmental impact statements, environmental assessments (EAs), and categorical exclusions evaluations.  Our NEPA team, in compliance with the Council on Environmental Quality (CEQ) regulations, eliminates from detailed study those resource areas that would not experience significant adverse effects. This results in concise, focused, analytical, and cost-effective NEPA documents that achieve the three primary purposes of the NEPA process:

  • Consider environmental values in agency decision-making (comply with NEPA, CEQ Regulations, and agency-specific NEPA regulations), allowing for informed decisions, aware of potential environmental effects and, where at all possible, minimizing environmental effects.
  • Solicit, obtain, and consider information from the public (including regulatory agencies and tribes).
  • Provide data to the public and decision-maker, in plain language, prior to making the decision.



Successful Projects:

EA to Construct Small Arms Range Facilities, Naval Weapons Station Yorktown, VA (U.S. Navy)

Our NEPA specialists conducted a thorough evaluation of the potential direct, indirect, and cumulative impacts associated with the construction and operation of a proposed small arms range facility, eliminating from detailed study those resource areas that would not experience significant adverse effects. Our ability to obtain, analyze, and interpret varying types of project-specific geospatial data to determine the potential effects of the Proposed Action facilitated compliance with the NEPA, as well as other environmental laws and regulations.

We facilitated communication between the design/construction team, the proposed range users, the regulatory community, the public, and other interested parties. Early collaboration among these stakeholder groups informed the alternatives development process and led to a more cost-effective range design that meets training requirements while minimizing potential environmental effects.

Our staff coordinated with the U.S. Army Public Health Command to analyze potential noise effects from the construction and operation of the proposed range facility. We quantified wetlands/waters of the U.S. impacts for the proposed range siting and design alternatives based upon a U.S. Army Corps of Engineers preliminary jurisdictional determination. The resultant data was then leveraged to obtain a Clean Water Act Section 404/401 permit for the construction of the range facilities. NEPA specialists identified and documented state-level regulatory requirements for the establishment and operation of public waterworks system to support the operation of the proposed range facility. We also responded to a Coastal Consistency Determination information request from the Virginia Department of Environmental Quality to address concerns with regard to impacts to Chesapeake Bay Protection Areas and state-listed threatened and endangered species.

EA / Finding of No Significant Impact for Site Development Plan, Rome Readiness Center, GA (Georgia Army National Guard)

Stell is completing the environmental work elements in support of the development of a Site Development Plan at the Rome Readiness Center. Our team of NEPA specialists, environmental scientists, and archaeologists has:

  • Managed wetlands/waters of the U.S. delineation that received preliminary Jurisdictional Determination from the U.S. Army Corps of Engineers.
  • Completed an Environmental Condition of Properties preconstruction assessment that was approved by the Georgia Department of Military Affairs.
  • Completed a Phase I archaeological survey in accordance with appropriate federal and state legislation and regulations.
  • Prepared the Draft Description of Proposed Actions and Alternatives

The EA includes an assessment of potential direct, indirect, and cumulative impacts and mitigation measures. Stell also will prepare the Finding of No Significant Impact, Notice of Availability, and geographic information system data. Our NEPA specialists will assist the Georgia Army National Guard in addressing public comments and prepare mitigation alternatives and responses for comments that question or identify adverse impacts associated with the proposed action.


EA, Tree Management Plan to Preserve Flight Safety, Dobbins Air Reserve Base, GA (U.S. Air Force)

Stell prepared an EA to evaluate potential environmental effects associated with plans to manage tree obstructions within and around the Dobbins Air Reserve Base airfield. The proposed action was needed to preserve flight line safety both on and off the installation. Complexity resulted from the high percentage of private property that needed to be analyzed. Stell developed the environmental assessment consistent with federal regulations and the U.S. Air Force Environmental Impact Analysis Process.

Topographic survey of tree stands was used to identify those that constituted obstructions in accordance with Federal Aviation Administration regulations. Stell used these data to evaluate potential environmental impacts associated with the proposed action.

Stell supported a public meeting to present the findings of environmental assessment. The public meeting offered attendees an opportunity to discuss concerns about the proposed action. The environmental assessment concluded with a Finding of No Significant Impact. The Air Force is now positioned to implement the proposed action and has a legally sufficient environmental assessment in full compliance with NEPA to enhance the safety of its airfield for the operators and the communities adjacent to the installation.
