Minn. R. agency 141, ch. 4410, SUBSTITUTE FORMS OF ENVIRONMENTAL REVIEW, pt. 4410.4000
An RGU may use a series of tiered EISs to fulfill environmental review requirements for an action where decisions on which alternative to select must be made in stages, progressing from the general to the specific. Prior to each decision which would eliminate from further consideration any alternatives under consideration, a tiered EIS must be completed which addresses the issues and alternatives relevant to the decisions to be made in that tier, at a level of detail appropriate to that tier. The level of detail in earlier tiers need not be as great as that in later tiers, provided that it is sufficient to reasonably inform decision makers of the significant environmental, economic, employment, and sociological impacts of the choices made in that tier.
The procedures for preparing tiered EISs shall be the same as those for a regular EIS, as specified in parts 4410.2100 to 4410.3000.
A tiered EIS may incorporate by reference material developed in an earlier tier.
