This EA originally addressed the sustainable design requirements contained in the Federal building rule.  Since the Notice of Proposed Rulemaking (NOPR), however, the DOE has modified and downscaled this rule to a procedural rule that only addresses only the green building certification requirements.  While the final rule is significantly downscaled from the proposed rule, due to the fact that the previous EA was put out for public review, is tied to this rulemaking, and in order to maintain the integrity of the NEPA process, we continue to use the EA process for this rulemaking.
