Nationwide 5 Permit Summary
<br />where pre - construction notification is not required and the
<br />project proponent wants confirmation that the activity is
<br />authorized by nationwide permit.
<br />Preservation: The removal of a threat to, or preventing the
<br />decline of, aquatic resources by an action in or near those
<br />aquatic resources. This term includes activities commonly
<br />associated with the protection and maintenance of aquatic
<br />resources through the implementation of appropriate legal and
<br />physical mechanisms. Preservation does not result in a gain of
<br />aquatic resource area or functions.
<br />Re- establishment: The manipulation of the physical,
<br />chemical, or biological characteristics of a site with the goal of
<br />returning natural/historic functions to a former aquatic
<br />resource. Re- establishment results in rebuilding a former
<br />aquatic resource and results in a gain in aquatic resource area
<br />and functions.
<br />Rehabilitation: The manipulation of the physical, chemical,
<br />or biological characteristics of a site with the goal of repairing
<br />natural/historic functions to a degraded aquatic resource.
<br />Rehabilitation results in a gain in aquatic resource function,
<br />but does not result in a gain in aquatic resource area.
<br />Restoration: The manipulation of the physical, chemical, or
<br />biological characteristics of a site with the goal of returning
<br />natural/historic functions to a former or degraded aquatic
<br />resource. For the purpose of tracking net gains in aquatic
<br />resource area, restoration is divided into two categories: re-
<br />establishment and rehabilitation.
<br />Riffle and pool complex: Riffle and pool complexes are
<br />special aquatic sites under the 404(b)(1) Guidelines. Riffle and
<br />pool complexes sometimes characterize steep gradient
<br />sections of streams. Such stream sections are recognizable by
<br />their hydraulic characteristics. The rapid movement of water
<br />over a course substrate in riffles results in a rough flow, a
<br />turbulent surface, and high dissolved oxygen levels in the
<br />water. Pools are deeper areas associated with riffles. A slower
<br />stream velocity, a streaming flow, a smooth surface, and a
<br />finer substrate characterize pools.
<br />Riparian areas: Riparian areas are lands adjacent to streams,
<br />lakes, and estuarine- marine shorelines. Riparian areas are
<br />transitional between terrestrial and aquatic ecosystems,
<br />through which surface and subsurface hydrology connects
<br />riverine, lacustrine, estuarine, and marine waters with their
<br />adjacent wetlands, non - wetland waters, or uplands. Riparian
<br />areas provide a variety of ecological functions and services
<br />and help improve or maintain local water quality. (See general
<br />condition 23.)
<br />Shellfish seeding: The placement of shellfish seed and/or
<br />suitable substrate to increase shellfish production. Shellfish
<br />seed consists of immature individual shellfish or individual
<br />shellfish attached to shells or shell fragments (i.e., spat on
<br />shell). Suitable substrate may consist of shellfish shells, shell
<br />fragments, or other appropriate materials placed into waters
<br />for shellfish habitat.
<br />Single and complete linear project: A linear project is a
<br />project constructed for the purpose of getting people, goods, or
<br />services from a point of origin to a terminal point, which often
<br />involves multiple crossings of one or more waterbodies at
<br />separate and distant locations. The term "single and complete
<br />Page 10
<br />project" is defined as that portion of the total linear project
<br />proposed or accomplished by one owner /developer or
<br />partnership or other association of owners /developers that
<br />includes all crossings of a single water of the United States
<br />(i.e., a single waterbody) at a specific location. For linear
<br />projects crossing a single or multiple waterbodies several
<br />times at separate and distant locations, each crossing is
<br />considered a single and complete project for purposes of NWP
<br />authorization. However, individual channels in a braided
<br />stream or river, or individual arms of a large, irregularly
<br />shaped wetland or lake, etc., are not separate waterbodies, and
<br />crossings of such features cannot be considered separately.
<br />Single and complete non - linear project: For non - linear
<br />projects, the term "single and complete project" is defined at
<br />33 CFR 330.2(i) as the total project proposed or accomplished
<br />by one owner /developer or partnership or other association of
<br />owners /developers. A single and complete non - linear project
<br />must have independent utility (see definition of "independent
<br />utility "). Single and complete non - linear projects may not be
<br />" piecemealed" to avoid the limits in an NWP authorization.
<br />Stormwater management: Stormwater management is the
<br />mechanism for controlling stormwater runoff for the purposes
<br />of reducing downstream erosion, water quality degradation,
<br />and flooding and mitigating the adverse effects of changes in
<br />land use on the aquatic environment.
<br />Stormwater management facilities: Stormwater
<br />management facilities are those facilities, including but not
<br />limited to, stormwater retention and detention ponds and best
<br />management practices, which retain water for a period of time
<br />to control runoff and/or improve the quality (i.e., by reducing
<br />the concentration of nutrients, sediments, hazardous
<br />substances and other pollutants) of stormwater runoff.
<br />Stream bed: The substrate of the stream channel between the
<br />ordinary high water marks. The substrate may be bedrock or
<br />inorganic particles that range in size from clay to boulders.
<br />Wetlands contiguous to the stream bed, but outside of the
<br />ordinary high water marks, are not considered part of the
<br />stream bed.
<br />Stream channelization: The manipulation of a stream's
<br />course, condition, capacity, or location that causes more than
<br />minimal interruption of normal stream processes. A
<br />channelized stream remains a water of the United States.
<br />Structure: An object that is arranged in a definite pattern of
<br />organization. Examples of structures include, without
<br />limitation, any pier, boat dock, boat ramp, wharf, dolphin,
<br />weir, boom, breakwater, bulkhead, revetment, riprap, jetty,
<br />artificial island, artificial reef, permanent mooring structure,
<br />power transmission line, permanently moored floating vessel,
<br />piling, aid to navigation, or any other manmade obstacle or
<br />obstruction.
