tion (e.g., dredging for intake channels, cofferdam construction) ` coordinating this review with the District Office of the Corps of Engineers. (k) Identify sediments, petroleum products, pesticides, fertilizers, heavy metals, and other potential pollutants entering affected water bodies. ` Consider both the points of entry of site drainage into surface-water bodies and the areal extent of impact by suspended materials and siltation. ` Determine the potential for reversibility of impacts following completion of construction. ` Assess plans for maintenance of siltation ponds or catchment basins. (l) Identify potential clearing along reaches of streams, rivers, and other water bodies. ` Identify water bodies where such habitat alterations will occur and indicate the extent of such changes. ` Compare this with the extent of remaining similar habitats in the region. (m) Identify potential dewatering effects on groundwater supply, wetlands (protected under Executive Order 11990 as amended by Executive Order 12608), and other aquatic habitats. ` Consider the location and areal extent of any wetlands that will be drained. ` Determine the relative extent of comparable wetlands in the region and, as in item (g) above, address the relative importance to the ecosystem of the impacted wetlands in comparison with the regional wetlands. October 1999 4.3.2-9 NUREG-1555 ` Examine the potential for reversibility of impacts and environmental improvement following construction. (n) Identify disposal plans for dredged material and placement of fill material. ` Identify the areal extent of any water bodies or wetlands that would receive dredge spoils during construction. ` Consider the relative extent of similar water bodies and wetlands in the region, and in this context, analyze the importance of the impacted wetlands and water bodies to the ecosystem. ` Coordinate this review with the District Office of the Corps of Engineers. (o) Ensure that aquatic species expected to become
