There are 3 levels of analysis:
A category of actions determined individually or cumulatively to nothave a significant effect on the quality of the human environment.
An analysis determines whether or not a federal undertaking would significantly affect the environment
An EIS is a more detailed evaluation of the proposed action and its alternatives.
Current project site environmental baseline conditions and the methodology or source of information used
The potential impacts associated with the project
The mitigation measures used to reduce adverse impacts and monitoring conducted to ensure the effectiveness of the implemented measures.
Site Characterization (baseline conditions)
Desktop survey for data/information collection
These type of programs could result in significant cost and schedule implications if they are not well planned during early project development phase.
NRC 3-Level Standard of Significance
Environmental effects are not detectable or are so minor that they will neither destabilize nor noticeably alter any important attribute of the resource.
Environmental effects are sufficient to alter noticeably, but not to destabilize, an important attribute of the resource.
Environmental effects are clearly noticeable and are sufficient to destabilize an important attribute of the resource.
Cumulative impacts of an action are the total effects on a resource, ecosystem, or human community of the action and all other activities affecting that resource no matter what entity (federal, non-federal, or private) is taking the action.
Key Areas of Consideration
Consequences of unsustainable water management:
the Aral Sea in 1989 and in 2003
Power plant cooling
Wet cooling system with evaporate recovery
Hybrid wet-dry cooling system
(up to 80% reduction)
Decreasing water consumption
Increasing capital & operating costs
Dry cooling system
