Environmental Quality Board Cumulative Impacts Definition

The Minnesota Environmental Quality Board (EQB) is currently proposing amendments to its rules governing environmental reviews, Environmental Assessment Worksheets (EAW) and Environmental Impact Statements (EIS). The proposed amendments address a number of different aspects regarding mandatory environmental review.

One of the important amendments being proposed is under the definitions relating to “cumulative impacts”, as cumulative impacts need to be addressed in environmental review. Under current rules, cumulative impact is defined as:

“Cumulative impact" means the impact on the environment that results from incremental effects of the project in addition to other past, present, and reasonably foreseeable future projects regardless of what person undertakes the other projects. Cumulative impacts can result from individually minor but collectively significant projects taking place over a period of time.

The amendment adds a definition for “cumulative potential effects”;


"Cumulative potential effects" means the effect on the environment that results from the incremental effects of a project in addition to other projects in the environmentally relevant area that might reasonably be expected to affect the same environmental resources, including future projects actually planned or for which a basis of expectation has been laid, regardless of what person undertakes the other projects or what jurisdictions have authority over the projects. Significant cumulative potential effects can result from individually minor projects taking place over a period of time. In analyzing the contributions of past projects to cumulative potential effects, it is sufficient to consider the current aggregate effects of past actions. It is not required to list or analyze the impacts of individual past actions, unless such information is necessary to describe the cumulative potential effects. In determining if a basis of expectation has been laid for a project, an RGU must determine whether a project is reasonably likely to occur and, if so, whether sufficiently detailed information is available about the project to contribute to the understanding of cumulative potential effects. In making these determinations, the RGU must consider: whether any applications for permits have been filed with any units of government; whether detailed plans and specifications have been prepared for the project; whether future development is indicated by adopted comprehensive plans or zoning or other ordinances; whether future development is indicated by historic or forecasted trends; and any other relevant factors.

EQB has scheduled public hearings on the proposed amendments to be held around the State.
