NPPE Environmental and Social Responsibilities 4 — Questions and Answers
Question 1: Under NEPA, what is the threshold document required before a federal agency decides whether a full Environmental Impact Statement is necessary?
- Environmental Assessment (EA) (Correct answer)
- Finding of No Significant Impact (FONSI)
- Categorical Exclusion (CE)
- Record of Decision (ROD)
Correct answer: Environmental Assessment (EA)
An Environmental Assessment (EA) is the preliminary document used to determine whether a proposed federal action requires a full EIS.
Question 2: A licensed engineer discovers that a completed stormwater management design will likely cause downstream erosion in a protected wetland. What is the engineer's primary obligation?
- Notify the client and recommend corrective measures (Correct answer)
- Keep the information confidential to protect the client
- Wait for regulatory agencies to identify the problem
- File a patent on the corrective design before disclosing
Correct answer: Notify the client and recommend corrective measures
Engineers must hold public safety and environmental protection paramount and are obligated to inform the client and recommend remediation.
Question 3: Which federal law specifically governs the cleanup of contaminated soil and groundwater at abandoned hazardous waste sites in the US?
- CERCLA (Superfund) (Correct answer)
- RCRA
- TSCA
- CWA
Correct answer: CERCLA (Superfund)
CERCLA (Comprehensive Environmental Response, Compensation, and Liability Act), commonly known as Superfund, governs cleanup of hazardous waste sites.
Question 4: In a life-cycle assessment (LCA), which phase evaluates the environmental burdens associated with a product from raw material extraction through end-of-life disposal?
- Inventory analysis
- Impact assessment (Correct answer)
- Goal and scope definition
- Interpretation
Correct answer: Impact assessment
The impact assessment phase in LCA translates inventory data into potential environmental impacts across the product's entire life cycle.
Question 5: A construction project in a US city requires a permit under Section 404 of the Clean Water Act. What activity does this permit regulate?
- Discharge of dredged or fill material into waters of the US (Correct answer)
- Point-source discharge of industrial wastewater
- Air emissions from construction equipment
- Disposal of solid waste at a permitted landfill
Correct answer: Discharge of dredged or fill material into waters of the US
Section 404 permits, administered by the Army Corps of Engineers, regulate the discharge of dredged or fill material into navigable waters and wetlands.
Question 6: Which sustainability principle requires that resource consumption not exceed the rate at which natural systems can regenerate those resources?
- Carrying capacity
- Ecological footprint
- Sustainable yield (Correct answer)
- Precautionary principle
Correct answer: Sustainable yield
Sustainable yield is the principle that harvesting or consumption should not exceed the regeneration rate of the natural resource.
Question 7: An engineering firm is hired to design a highway through a low-income community. Under the principle of environmental justice, what is most important for the design team to do?
- Ensure the community has meaningful participation in the decision-making process (Correct answer)
- Minimize project costs regardless of community impact
- Prioritize speed of construction over stakeholder engagement
- Defer all community concerns to the regulatory agency
Correct answer: Ensure the community has meaningful participation in the decision-making process
Environmental justice requires that no community bear a disproportionate share of environmental burdens and that all communities have meaningful involvement in decisions affecting them.
