Riparian zones include the plant communities along stream and river banks. Riparian zone health directly affects stream health by preventing erosion and promoting habitat biodiversity. Riparian zone plantings are integral, and often required, for stream mitigation, restoration, and enhancement. Plant species of all strata can be used to help create a healthy riparian zone. Species selection is based on ecosystem, wildlife benefit, cost effectiveness, and availability.
BSC has helped to plan, implement, coordinate and monitor many riparian zone plantings in order to re-establish healthy stream ecosystems in impacted areas. A healthy riparian zone promotes stream health through canopy cover, nutrient cycling, invasive species prevention and much more.
According to the Tennessee Department of Environment and Conservation website:
Persons who wish to make an alteration to a stream, river, lake or wetland must first obtain a water quality permit. Physical alterations to properties of waters of the state require an Aquatic Resource Alteration Permit (ARAP) or a §401 Water Quality Certification (§401 certification). Examples of stream alterations that require a permit from the Tennessee Division of Water Resources (division) include:
Dredging, excavation, channel widening, or straightening
Bank sloping; stabilization
Water diversions or withdrawals
Dams, weirs, dikes, levees or other similar structures
Flooding, excavating, draining and/or filling a wetland
Road and utility crossings
A federal permit may also be required from the U. S. Army Corps of
Engineers (Corps) for projects that include the discharge of dredged or
fill material into waters of the U.S. including wetlands. This permit is
called a §404 permit. When a §404 is required from the Corps, a §401
certification must first be obtained from the division. A §401
certification affirms that the discharge would not violate Tennessee’s
water quality standards. The application process for a §401
certification is the same as the ARAP process.
General Permits are developed and maintained by the division to
provide a streamlined, expedited means of authorizing projects that
singularly or cumulatively propose minor impacts to water resources.
Implementation of some types of conservation practices on agricultural land requires coverage under TDEC’s Construction General Stormwater Permit (CGP) and/or ARAPs. In an effort to streamline this permitting process for agencies invloved, a fact sheet was cooreratively developed to help farmers, landowners and other program participants to determine when a permit is needed or not.
Biological Systems Consultants, Inc. can provide support for the ARAP process.
According to the Kentucky Division of Water all discharges to waters of the Commonwealth require a permit through the Kentucky Pollutant Discharge Elimination System (KPDES). Such permits include effluent limitations that are developed from technology-based and water quality-based criteria. Our team of technicians can provide General and Individual Permitting and compliance services to help you navigate your project needs in a cost efficient manner.
As required by Kentucky Revised Statute 151.250, stream construction permits are required for any development occurring in, along, or across a stream.

We recently completed another hydrologic determinations (HD) in Campbell County, in the State of Tennessee for the Tennessee Department of Environment and Conservation (TDEC) . These are required by Tennessee law and are conducted by our trained field staff. These determinations use a combination of primary and secondary field indicators for the assessment. The secondary indicators include assess geomorphology, hydrology, and biology related characteristics within the watercourse to identify if it is a wet weather conveyance.
We are now preparing the Aquatic Resource Alteration Permit (ARAP) for the streams identified within the site boundary and also preparing the Nationwide Permit (NWP) Application for the U.S. Army Corps of Engineers Nashville District.
We recently completed multiple hydrologic determinations in the State of Tennessee. These are required by Tennessee law and are conducted by our trained field staff. These determinations use a combination of primary and secondary field indicators for the assessment. The secondary indicators include assess geomorphology, hydrology, and biology related characteristics within the watercourse to identify if it is a wet weather conveyance.
Jurisdictional Determination projects were conducted at these Kentucky sites in the last couple months. One project was determined to not require a permit while the other was found to contain one jurisdictional intermittent stream channel.
Jurisdictional Determinations are conducted by BSC personnel in support of the requirements of Section 404 of the Clean Water Act (CWA) to identify “waters of the U.S.” as identified by the United States Army Corps of Engineers (USACE). Field surveys for the determination were conducted in accordance with the 1987 USACE Wetlands Delineation Manual (USACE, 1987) and the Final Regional Supplement for the Piedmont and Eastern Mountains Region (USACE, 2012). BSC investigators also evaluate the potential for federal jurisdiction under Section 404 of the CWA over aquatic features in the study area based on USACE revised guidance published December 2, 2008. In addition we conduct determinations in accordance with the new “waters rule” that is now in effect in 26 states.
Kentucky contains seven Level III ecoregions. These ecoregions were defined by similarities in geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology. The proposed project area is located within the Central Appalachians ecoregion (69) which drains 23,698 square miles. Specifically, the project is within the Level IV ecoregion 69e (Cumberland Mountain Thrust Block) which encompasses 1,083 square miles. The topography in this area is characterized as highly dissected, hilly and mountainous plateau with steep ridges, very narrow ridge tops, narrow valleys, and deep coves. 69e contains elevations ranging from approximately 980’- 4,139’ in Kentucky and contains streams with high gradients, waterfalls, many riffles, few pools, and cobble or boulder substrates (Woods et al., 2002).

Aerial ecological assessments using the newest technology (EcoDrones) available to us we have now integrated aerial imaging into our list of services. Our custom built EcoDrones (UAVs, sUAS) allow us to capture low-elevation high resolution color video or still photos for ecological assessments of watersheds. This allows us to further document ecological resources in a way we have not been previously capable. Environmental assessments will never be the same.
Using drone technology we can provide ecological assessments using low-elevation high-resolution imagery of the ecosystem within a project area or site. Restoring and maintaining the natural environment continues to be an important issue. BSC specializes in helping clients solve the challenges of growing their businesses while addressing environmental concerns.
We conduct ecological assessments including biological, aquatic, fish, bird, plant, tree, wetland, stream habitat, and other natural resource assessments. BSC provides expertise in both water resources and aquatic systems management, which requires the understanding of input and output relationships between water systems and their its influence on natural processes. We develop client specific solutions that protect sensitive resources and infrastructure including roads, wetland habitat, rivers, streams, recreational facilities, and infrastructure.
Our client was looking to open a new operation, and hired BSC to perform a preliminary evaluation on an area encompassing 2,000 acres. Our study identified the potential of the proposed mines impacts to archaeological resources, streams and wetlands, prepared a stream restoration plan for the SMCRA permit, a jurisdictional determination or the Corps of Engineers (section 404), and a Section 401 (Water Quality Certification) for the State of Kentucky. The Corps permit was able to be avoided by revising the footprint of the permit while still achieving an economically beneficial project.

Macroinvertebrate Collection and Analysis | Aquatic Assessments – The following steps are taken from the KDOW SOP manual, and describe the methodology for collecting a multi-habitat sample in a wadeable stream:
“1. The investigator will sample a variety of non-riffle habitats with the aid of an 800 x
900 μm mesh triangular or D-frame dip net.
2. Each habitat will be sampled in at least three (3) replicates.
3. After all habitats have been sampled, the contents of the mesh wash bucket will be
composited into a glass, sampling jar with 95% ETOH.
4. The wash bucket will be picked clean of any remaining macroinvertebrates.
5. The sample jar will be labeled with appropriate information (Section 8.D.) and will be
ready for transport to the lab for analysis.
6. Each of these following habitats will be sampled:
A. Undercut Banks/Root Mats
1. These are sampled by placing a large root wad into a triangular or D-frame dip
net and shaking vigorously.
2. The contents are removed from the dip net and placed into a mesh wash bucket.
3. If undercut banks are present in both run and pool areas, each is sampled
separately with three (3) replicates.
B. Marginal Emergent Vegetation (exclusive of water willow, Justicia Americana, beds)
1. This habitat is sampled by thrusting (i.e., “jabbing”) the dip net into the
vegetation for approximately 1m, and then sweeping through the area to collect
2. Material is then rinsed in the wash bucket and any sticks, leaves and vegetation
are thoroughly washed and inspected before discarding.
C. Bedrock or Slab-Rock Habitats
1. These habitats are sampled by placing the edge of the dip net flush on the
substrate, and disturbing approximately 0.1 m2 of area to dislodge attached
2. Material is emptied into a wash bucket, rinsed, inspected for organisms, and
D. Justicia americana (water willow) Beds
1. These are sampled by working the net through a 1m section in a jabbing
2. The material is then emptied into a wash bucket and any J. americana stems
are thoroughly washed, inspected and discarded.
E. Leaf Packs
1. Leaf packs are preferably collected from “conditioned” (i.e., not new-fall
material) material when possible.
2. Samples are taken from a diversity of habitats (i.e., riffles, runs and pools) and
placed into the wash bucket.
3. The material is thoroughly rinsed to dislodge organisms, inspected and
F. Silt, Sand, and Fine Gravel
1. A U.S. No. 10 sieve is used to sort larger invertebrates (e.g., mussels,
burrowing mayflies, dragonfly larvae) from silt, sand and fine gravel by scooping
the substrate to an approximate depth of 5cm.
2. A variety of collection sites are sampled in order to obtain three (3) replicates
in each substrate type where available (silt, sand and fine gravel).
G. Aufwuchs Sample
1. Small invertebrates associated with this habitat are obtained by washing a small
amount of rocks, sticks, leaves, filamentous algae and moss into a medium-sizedbucket half filled with water.
2. The material is then elutriated and sieved with the nitex sampler/mesh.
H. Rock Picking
1. Benthic macroinvertebrates are picked from 15 rocks (large cobble/small
boulders; 5 each from riffle, run and pool).
2. Selected rocks are washed in a bucket half filled with water and then carefully
inspected to remove organisms.
I. Wood Sample
1. Pieces of submerged wood, ranging from roughly 3 to 6 meters (10 to 20 linear
feet) in length and ranging from 5–15 cm (2–6 inches) in diameter, are
individually rinsed into the wash bucket.
2. Pieces of wood are inspected for burrowers and crevice dwellers and are
removed with fine-tipped forceps.
3. Large diameter, well-aged logs should be inspected and handpicked with finetipped
After the samples have been processed our aquatic entomologists identify each organism and provide an analysis of the results.
