    Subpart D_Environmental Review Process: Documentation, Range of 
           Activities, Project Aggregation and Classification
 
Sec. 58.32  Project aggregation.

    (a) A responsible entity must group together and evaluate as a 
single project all individual activities which are related either on a 
geographical or functional basis, or are logical parts of a composite of 
contemplated actions.
    (b) In deciding the most appropriate basis for aggregation when 
evaluating activities under more than one program, the responsible 
entity may choose: functional aggregation when a specific type of 
activity (e.g., water improvements) is to take place in several

[[Page 415]]

separate locales or jurisdictions; geographic aggregation when a mix of 
dissimilar but related activities is to be concentrated in a fairly 
specific project area (e.g., a combination of water, sewer and street 
improvements and economic development activities); or a combination of 
aggregation approaches, which, for various project locations, considers 
the impacts arising from each functional activity and its 
interrelationship with other activities.
    (c) The purpose of project aggregation is to group together related 
activities so that the responsible entity can:
    (1) Address adequately and analyze, in a single environmental 
review, the separate and combined impacts of activities that are 
similar, connected and closely related, or that are dependent upon other 
activities and actions. (See 40 CFR 1508.25(a)).
    (2) Consider reasonable alternative courses of action.
    (3) Schedule the activities to resolve conflicts or mitigate the 
individual, combined and/or cumulative effects.
    (4) Prescribe mitigation measures and safeguards including project 
alternatives and modifications to individual activities.
    (d) Multi-year project aggregation--(1) Release of funds. When a 
recipient's planning and program development provide for activities to 
be implemented over two or more years, the responsible entity's 
environmental review should consider the relationship among all 
component activities of the multi-year project regardless of the source 
of funds and address and evaluate their cumulative environmental 
effects. The estimated range of the aggregated activities and the 
estimated cost of the total project must be listed and described by the 
responsible entity in the environmental review and included in the RROF. 
The release of funds will cover the entire project period.
    (2) When one or more of the conditions described in Sec. 58.47 
exists, the recipient or other responsible entity must re-evaluate the 
environmental review.
