Read the first 7 Environmental Impact Assessment & Resource Management flashcards as text

  1. Under NEPA, which document is prepared when the significance of a proposed federal action's environmental impact is uncertain?

    Answer: Environmental Assessment (EA)

    An Environmental Assessment (EA) is the screening-level document used to determine whether a full EIS is required when impact significance is unclear.

  2. Which resource management approach sets allowable harvest or extraction rates equal to the rate of natural regeneration?

    Answer: Maximum sustainable yield

    Maximum sustainable yield (MSY) is the largest harvest that can be taken indefinitely without depleting the resource base.

  3. In an EIA scoping process, the primary objective is to:

    Answer: Identify significant issues and alternatives to be studied

    Scoping narrows the EIA's focus to the most significant issues and feasible alternatives so resources are not wasted on minor concerns.

  4. A water footprint assessment distinguishes between blue, green, and grey water. Grey water refers to:

    Answer: The volume of freshwater needed to dilute pollutants to acceptable levels

    Grey water footprint quantifies the freshwater volume required to assimilate a pollutant load to meet ambient water quality standards.

  5. Which international protocol established binding targets for stratospheric ozone-depleting substances and is considered a model for global environmental agreements?

    Answer: Montreal Protocol

    The 1987 Montreal Protocol phased out chlorofluorocarbons and other ozone-depleting substances and is widely cited as the most successful global environmental treaty.

  6. A life-cycle assessment (LCA) 'system boundary' defines:

    Answer: Which processes and flows are included or excluded from the study

    The system boundary specifies which unit processes are included in an LCA so results are transparent, reproducible, and fit for the study's goal.

  7. The concept of 'virtual water' is most useful for understanding:

    Answer: Hidden water consumption embedded in traded goods

    Virtual water refers to the water used in the production of goods and services, making it a key concept for understanding water trade and resource efficiency globally.
