DEQ Environmental Impact Assessment 1 — Questions and Answers
Question 1: Under the National Environmental Policy Act (NEPA), what document is prepared for federal actions with potentially significant environmental impacts?
- Environmental Site Assessment (ESA)
- Environmental Impact Statement (EIS) (Correct answer)
- Environmental Compliance Certificate (ECC)
- Programmatic Environmental Review (PER)
Correct answer: Environmental Impact Statement (EIS)
NEPA requires federal agencies to prepare an Environmental Impact Statement (EIS) for major federal actions that may significantly affect the quality of the human environment.
Question 2: What is an Environmental Assessment (EA) under NEPA and how does it differ from an EIS?
- An EA is a shorter, preliminary document used to determine whether an EIS is required, while an EIS is a full analysis of significant impacts (Correct answer)
- An EA is required for all federal actions, while an EIS is only required for private projects
- An EA takes longer to complete than an EIS because it involves more public participation
- An EA is prepared by the project applicant, while an EIS is always prepared by the lead federal agency
Correct answer: An EA is a shorter, preliminary document used to determine whether an EIS is required, while an EIS is a full analysis of significant impacts
An EA is a concise NEPA document that determines whether a proposed action's impacts are significant; if not, a Finding of No Significant Impact (FONSI) is issued instead of proceeding to a full EIS.
Question 3: What is a 'categorical exclusion' (CE) under NEPA?
- A category of actions that a federal agency has determined typically have no significant environmental impact and therefore do not require an EA or EIS (Correct answer)
- An exemption from all environmental review for projects located on federal lands
- A special permit allowing federal agencies to waive environmental review during declared national emergencies
- A provision allowing states to exclude certain project types from their state environmental review processes
Correct answer: A category of actions that a federal agency has determined typically have no significant environmental impact and therefore do not require an EA or EIS
Categorical exclusions identify classes of actions that an agency has determined, based on experience, do not individually or cumulatively cause significant environmental effects, streamlining the NEPA process.
Question 4: What is the 'scoping' process in NEPA environmental review?
- The final step in the EIS process where the agency selects its preferred alternative
- An early public process used to identify the range of issues, alternatives, and impacts to be analyzed in the EIS (Correct answer)
- The internal agency review of the EIS before it is released for public comment
- The scientific assessment of baseline environmental conditions at a project site
Correct answer: An early public process used to identify the range of issues, alternatives, and impacts to be analyzed in the EIS
Scoping is an early public participation process that identifies significant issues for the EIS, focuses the analysis on important questions, and eliminates insignificant ones, making the review more targeted and efficient.
Question 5: What does NEPA require agencies to analyze regarding 'alternatives' to a proposed action?
- Only the proposed action and a no-action alternative are required
- A reasonable range of alternatives including the no-action alternative, the preferred alternative, and other feasible alternatives (Correct answer)
- All theoretically possible alternatives regardless of feasibility or practicality
- Only alternatives that would result in zero environmental impact
Correct answer: A reasonable range of alternatives including the no-action alternative, the preferred alternative, and other feasible alternatives
NEPA requires analysis of a reasonable range of alternatives including no-action, which allows decision-makers and the public to compare the environmental consequences of different approaches.
Question 6: What is the public comment period for a Draft EIS under NEPA regulations?
- 15 days
- 30 days
- 45 days (Correct answer)
- 60 days
Correct answer: 45 days
CEQ regulations establish a minimum 45-day public comment period for Draft EISs, giving interested parties adequate time to review and comment on the analysis.
