(a) As specified in 40 CFR 1508.28, tiering is a process of covering general environmental review in a broad PEA, followed by subsequent narrower scope analysis to address specific proposed actions, action stages, or sites. FSA will use tiering when FSA prepares a broad PEA and subsequently prepares a site-specific ESW, EA, or PEA for a proposed action included within the program addressed in the original, broad PEA.
(b) When FSA uses tiering in a broad PEA, the subsequent ESW, EA, or PEA will:
(1) Summarize the issues discussed in the broader statement;
(2) Incorporate by reference the discussions from the broader statement and the conclusions carried forward into the subsequent tiered analysis and documentation; and
(3) State where the PEA document is available.
