Nationwide Permit 6 Summary
<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:
<br />Reestablishment 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 next 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 />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 ofNWP
<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(1) 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 />Page 12
<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.
<br />Tidal wetland: A tidal wetland is a jurisdictional wetland that
<br />is inundated by tidal waters. Tidal waters rise and fall in a
<br />predictable and measurable rhythm or cycle due to the
<br />gravitational pulls of the moon and sun. Tidal waters end
<br />where the rise and fall of the water surface can no longer be
<br />practically measured in a predictable rhythm due to masking
<br />by other waters, wind, or other effects. Tidal wetlands are
<br />Tribal lands: Any lands title to which is either: (1) Held in
<br />trust by the United States for the benefit of any Indian tribe or
<br />individual; or (2) held by any Indian tribe or individual subject
<br />to restrictions by the United States against alienation.
<br />Tribal rights: Those rights legally accruing to a tribe or tribes
<br />by virtue of inherent sovereign authority, unextinguished
<br />aboriginal title, treaty, statute, judicial decisions, executive
<br />order or agreement, and that give rise to legally enforceable
<br />remedies.
<br />Vegetated shallows: Vegetated shallows are special aquatic
<br />sites under the 404(b)(1) Guidelines. They are areas that are
<br />permanently inundated and under normal circumstances have
<br />rooted aquatic vegetation, such as seagrasses in marine and
<br />estuarine systems and a variety of vascular rooted plants in
<br />freshwater systems.
<br />Waterbody: For purposes of the NWPs, a waterbody is a
<br />jurisdictional water of the United States. If a wetland is
<br />adjacent to a waterbody determined to be a water of the United
<br />States, that waterbody and any adjacent wetlands are
<br />considered together as a single aquatic unit (see 33 CFR
<br />328.4(c)(2)). Examples of "waterbodies" include streams,
<br />rivers, lakes, ponds, and wetlands.
