What levels of environmental analysis must a Federal agency charged with building public works consider for each project? What are the criteria for choosing each of these?
I tried Googling for info on this question, but I can't find anything good.
Thanks for the help.
These sites may help you. If not, check your city or college library.

When a Federal agency is charged with building public works projects, they must consider several levels of environmental analysis. These levels are required to assess potential impacts on the environment and to ensure compliance with relevant laws and regulations. The specific levels of analysis depend on the scale and nature of the project. Here are the primary levels of environmental analysis typically considered:
1. Categorical Exclusion (CE): This level is applicable to smaller-scale projects that are unlikely to have significant environmental impacts. Projects meeting certain criteria or falling within specific categories are deemed categorically excluded from more in-depth analysis. The criteria for a CE may vary between agencies, so it is important to consult the guidelines of the specific agency involved.
2. Environmental Assessment (EA): If a project does not qualify for categorical exclusion, an Environmental Assessment is conducted. An EA is a more rigorous examination that determines whether the project will have a significant impact on the environment. During this analysis, potential impacts are identified and evaluated. If it is determined that the impacts are not significant, the process can proceed with a Finding of No Significant Impact (FONSI). Otherwise, it moves to the next level.
3. Environmental Impact Statement (EIS): For projects with the potential for significant environmental impacts, an Environmental Impact Statement is required. An EIS is the most comprehensive level of analysis. It includes a thorough evaluation of the project's environmental effects and alternatives. Public input and comments are also incorporated into the analysis. The criteria for preparing an EIS are typically outlined in the National Environmental Policy Act (NEPA) and agency-specific regulations.
The specific criteria for choosing each level of analysis are generally determined by federal regulations and the agency's own policies. Agencies typically have guidelines and thresholds that help determine when a project qualifies for categorical exclusion, requires an EA, or necessitates an EIS. These criteria consider factors such as project size, potential impacts on air quality, water resources, endangered species, historic sites, or communities, among others.
If you couldn't find detailed information on this topic through a simple Google search, I recommend visiting the website of the Federal agency responsible for the public works project you are interested in. Agency websites often provide specific guidance documents, manuals, or handbooks that outline their environmental analysis processes and criteria. These resources can provide more in-depth and accurate information about the requirements and criteria specific to that agency.
Remember, always refer to official sources and consult with relevant experts or professionals to obtain the most accurate and up-to-date information.
