Conservation Practice Standard (Ac.) 657 The return of a wetland and its functions to a close approximation of its original condition as it existed prior to disturbance on a former or degraded wetland site. To restore wetland function, value, habitat, diversity, and capacity to a close approximation of the pre-disturbance conditions by restoring: Conditions conducive to hydric soil maintenance. Wetland hydrology (dominant water source, hydroperiod, and hydrodynamics). Native hydrophytic vegetation (including the removal of undesired species, and/or seeding or planting of desired species). Original fish and wildlife habitats. This practice applies only to natural wetland sites with hydric soils which have been subject to the degradation of hydrology, vegetation, or soils. This practice is applicable only where the natural hydrologic conditions can be approximated by actions such as modifying drainage, restoring stream/floodplain connectivity, removing diversions, dikes, and levees, and/or by using a natural or artificial water source to provide conditions similar to the original, natural conditions. This practice does not apply to: The treatment of point and non-point sources of water pollution (Constructed Wetland - 656); The rehabilitation of a degraded wetland, the reestablishment of a former wetland, or the modification of an existing wetland, where specific wetland functions are augmented beyond the original natural conditions; possibly at the expense of other functions.(Wetland Enhancement - 659); The creation of a wetland on a site location which was historically (Wetland Creation - 658). The management of fish and wildlife habitat on wetlands restored under this standard. General Criteria Applicable to All Purposes This conservation practice is exempt from receiving coverage under TDEC's (Tennessee Department of Environment and Conservation) ARAP permits as long as NRCS provides technical or financial assistance for this conservation practice. This exemption allows this conservation practice to be installed adjacent to streams and/or wetlands, and for the outlet of the structure to be placed down through the stream channel bank and into the closest edge of the stream channel. The TDEC ARAP exemption does not change the permitting requirements for the U. S. Army Corps of Engineers permits (404), the Tennessee Valley Authority permits (26a – if located within the Tennessee River drainage area.), or any permits that may be required by local units of government.
