of Engineers Regulatory Program (33 CFR 320–330) or other official policy guidance contained in Memoranda of Agreement (MOA), Regulatory Guidance Letters (RGLs), etc. Part I simply highlights critical policies and procedures that are major factors in administering a consistent program nationwide. These critical policies and procedures, however, are those that the Major Subordinate Commands and CECW-OR will evaluate in our future consistency reviews. In addition, consistency with Part I will be a factor in responding to districts' requests for additional resources.
- Corps determines scope
- 33 CFR 325 Appendix B,C
Scope of analysis has two distinct elements, determining the Corps Federal action area and how the Corps will evaluate indirect, or secondary, adverse environmental effects. The Corps determines its action area under 33 CFR 325 Appendix B and C. Generally, the action area includes all waters of the United States, as well as any additional area of non-waters where the Corps determines there is adequate Federal control and responsibility to include it in the action area. The action area always includes upland areas in the immediate vicinity of the waters of the United States where the regulated activity occurs. For example, the action areas for a road access to uplands for a residential development is the road crossing of waters of the United States and the upland area in the immediate vicinity of the road crossing. In a similar case where there is not only the road crossing, but also considerable additional impacts to waters within the residential development (interior road crossings, house fills, stormwater control berms/dams, etc.), then the Corps action area is the whole residential development. The Corps analyzes all adverse environmental effects within the action area. In addition, the Corps is responsible for analyzing the direct and indirect impacts of its permit decisions, within the action area once the scope of analysis (which defines the corresponding action area) is properly determined. Direct impacts are those that happen in direct response to the permitted activity (e.g., the direct impact of dam construction is the loss of habitat in the dam footprint). Indirect impacts, on the other hand, are those removed in time and/or distance in relation to the permitted activity (e.g., the indirect impact of dam construction is the inundation of the area behind the dam). Another example would be habitat and/or fisheries impacts downstream of the dam associated with hydroperiod changes. Both direct and indirect impacts must be evaluated within site-specific and cumulative impact contexts. It is appropriate for the Corps to evaluate these impacts and render final permit and
