CEP Environmental Impact Analysis & Planning 2 — Questions and Answers
Question 1: Under NEPA, which document is prepared when the significance of a proposed federal action's environmental impacts is uncertain?
- Environmental Assessment (EA) (Correct answer)
- Environmental Impact Statement (EIS)
- Finding of No Significant Impact (FONSI)
- Record of Decision (ROD)
Correct answer: Environmental Assessment (EA)
An EA is a concise analysis used to determine whether an EIS is needed when significance is unclear.
Question 2: The concept of 'indirect effects' in an EIS refers to impacts that are:
- Caused by the action and occur later in time or farther in distance but are still foreseeable (Correct answer)
- Directly caused by the project construction activities
- Related to other agency actions in the same geographic area
- Mitigated through design changes before project approval
Correct answer: Caused by the action and occur later in time or farther in distance but are still foreseeable
Indirect effects are caused by the action but are spatially or temporally removed yet still reasonably foreseeable.
Question 3: Which scoping technique in EIS preparation specifically solicits input from federal, state, and local agencies as well as the public to identify key issues?
- Public scoping meetings (Correct answer)
- Agency coordination letters
- Interdisciplinary team review
- Preliminary environmental assessment
Correct answer: Public scoping meetings
Public scoping meetings are the formal NEPA mechanism to gather interagency and public input on what issues the EIS should address.
Question 4: A project's environmental footprint is evaluated against a 'baseline' that represents:
- Existing environmental conditions without the proposed action (Correct answer)
- Federal environmental quality standards for the region
- Conditions projected 20 years into the future
- Conditions at a similar undisturbed reference site
Correct answer: Existing environmental conditions without the proposed action
The baseline (affected environment) describes current conditions against which project impacts are measured.
Question 5: Which analytical method is commonly used in EIA to assess cumulative impacts across multiple projects?
- Geographic Information System (GIS) overlay analysis (Correct answer)
- Benefit-cost ratio calculation
- Environmental Justice Screening Tool (EJScreen) only
- Monte Carlo simulation exclusively
Correct answer: Geographic Information System (GIS) overlay analysis
GIS overlay analysis allows planners to spatially combine impacts from multiple projects to identify cumulative effects across a landscape.
Question 6: Under CEQ regulations, a 'tiered' EIS approach allows agencies to:
- Incorporate analyses from broad programmatic EISs into site-specific EISs without unnecessary repetition (Correct answer)
- Delay public comment periods until all project phases are designed
- Exclude private projects from NEPA review if a programmatic EIS exists
- Combine multiple unrelated federal actions into a single review
Correct answer: Incorporate analyses from broad programmatic EISs into site-specific EISs without unnecessary repetition
Tiering allows site-specific EISs to reference and build on programmatic analyses, avoiding redundancy.
Question 7: Which mitigation measure type involves modifying the project to avoid an adverse impact entirely?
- Avoidance (Correct answer)
- Minimization
- Rectification
- Compensation
Correct answer: Avoidance
Avoidance is the preferred and highest-ranking mitigation type in the mitigation hierarchy, eliminating impacts rather than reducing or offsetting them.
