Fatal Flaw Analysis: How it works
• Used to evaluate and screen full range of alternatives (solutions) identified
• Remaining feasible alternatives receive “Higher”level of analysis
• Fatal flaw screening:– Does alternative satisfy purpose, need and goals?– Does alternative have significant impacts?– Is alternative permittable?– Is alternative financially/physically feasible?– Is alternative clearly inferior to other alternatives?

Fatal Flaw Draft Matrix• Tool to “funnel” all alternatives (solutions)• Criteria based on Purpose and Need Statement
and regulatory requirements• This analysis less detailed than for feasible
alternatives• At this point do not have detailed information on
such categories as aesthetics and economic impact. These will be applied later to feasible alternatives
• Today’s run-through: Your choice!!
