PART 58_ENVIRONMENTAL REVIEW PROCEDURES FOR ENTITIES ASSUMING HUD 
ENVIRONMENTAL RESPONSIBILITIES--Table of Contents
 
   Subpart B_General Policy: Responsibilities of Responsible Entities
 
Sec. 58.15  Tiering.

    Responsible entities may tier their environmental reviews and 
assessments to eliminate repetitive discussions of the same issues at 
subsequent levels of review. Tiering is appropriate when there is a 
requirement to evaluate a policy or proposal in the early stages of 
development or when site-specific analysis or mitigation is not 
currently feasible and a more narrow or focused analysis is better done 
at a later date. The site specific review need only reference or 
summarize the issues addressed in the broader review. The broader review 
should identify and evaluate those issues ripe for decision and exclude 
those issues not relevant to the policy, program or project under 
consideration. The broader review should also establish the policy, 
standard or process to be followed in the site specific review. The 
Finding of No Significant Impact (FONSI) with respect to the broader 
assessment shall include a summary of the assessment and identify the 
significant issues to be considered in site specific reviews. Subsequent 
site-specific reviews will not require notices or a Request for Release 
of Funds unless the Certifying Officer determines that there are 
unanticipated impacts or impacts not adequately addressed in the prior 
review. A tiering approach can be used for meeting environmental review 
requirements in areas designated for special focus in local Consolidated 
Plans. Local and State Governments are encouraged to use the 
Consolidated Plan process to facilitate environmental reviews.
