What document assesses the expected environmental effects of a proposed action?

The Environmental Assessment is the correct document for assessing the expected environmental effects of a proposed action. This process serves as a preliminary analysis to identify potential environmental impacts and determine whether a more detailed Environmental Impact Statement (EIS) is required. The Environmental Assessment allows agencies to evaluate the potential consequences of their proposals on the environment, facilitating informed decision-making and ensuring compliance with environmental regulations. By providing this initial review, the Environmental Assessment can lead to either a finding of no significant impact or the need for further in-depth evaluation through an EIS, helping to protect environmental resources and promote sustainable practices.
