CWD Environmental Impact Assessment 2

Question 1

Under NEPA, which document is prepared when the significance of a proposed federal action's impacts is uncertain?

Accepted Answer

Environmental Assessment

Answer

An Environmental Assessment (EA) is prepared to determine whether a proposed action's impacts are significant enough to require a full EIS.

Question 2

Which wetland function is MOST directly evaluated by measuring water storage capacity during storm events?

Accepted Answer

Flood attenuation

Answer

Flood attenuation is assessed by measuring how much stormwater a wetland can store and slowly release, reducing downstream peak flows.

Question 3

A 'Secondary impact' in an EIA for a wetland project is BEST described as:

Accepted Answer

Induced development facilitated by new road access through a buffer

Answer

Secondary (indirect) impacts are later-occurring or farther-removed effects, such as induced development enabled by new infrastructure near a wetland.

Question 4

Which Section 404 permit type is MOST appropriate for a minor, routine wetland impact with minimal individual and cumulative effects?

Accepted Answer

Nationwide Permit

Answer

Nationwide Permits (NWPs) are pre-authorized general permits for categories of activities with minimal individual and cumulative adverse effects.

Question 5

When assessing cumulative impacts to wetlands, an EIA must consider:

Accepted Answer

Past, present, and reasonably foreseeable future actions in the region

Answer

NEPA and Corps regulations require cumulative impact analysis to include past, present, and reasonably foreseeable future actions that affect the same resource.
