nationwide permit summaries for NW27 and NW33. If the creation of the temporary catchment <br />basin(s) can be conducted via excavation only, i.e. without placing any material within <br />the stream or adjacent wetlands, the creation will not require permitting. The <br />restoration of the stream would require permitting. The catchment basin should be placed <br />outside of wetlands, to the maximum extent practicable, and any wetlands that cannot be <br />avoided should be excavated in such a way that the top 12-18 inches of topsoil will be <br />stockpiled seperately from the sub-soil. During restoration the sub-soil should be placed <br />first with the topsoil spread back on top. In order to ensure a stable stream reach after <br />restoration, a longitudinal profile of the stream should be taken at the area of the <br />proposed catchment basin prior to excavation. Please feel free to contact me with any <br />questions.
