Hydrologic Determination – Tennessee

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.

Tennessee Hydrologic Determination

Tennessee Hydrologic Determination (HDT) and Jurisdictional Determinations (JD) are conducted by our trained field staff and follow the Tennessee Department of Environment and Conservation Division of Water Pollution ControlGuidance For Making Hydrologic Determinations. This is required by law within the state of Tennessee under the following statute.

The following is taken from the TN statute:

Public Chapter No. 464 PUBLIC ACTS, 2009 1
STATE OF TENNESSEE
PUBLIC CHAPTER NO. 464
SENATE BILL NO. 632
Tennessee Code Annotated, Section 69-3-103, is amended by
adding the following language as new, appropriately designated subsections:
( ) “Wet weather conveyance” means, notwithstanding any other law or
rule to the contrary, man-made or natural watercourses, including natural
watercourses that have been modified by channelization:
(1) That flow only in direct response to precipitation runoff in their
immediate locality;
(2) Whose channels are at all times above the groundwater table;
(3) That are not suitable for drinking water supplies; and
(4) In which hydrological and biological analyses indicate that,
under normal weather conditions, due to naturally occurring ephemeral or
low flow there is not sufficient water to support fish, or multiple
populations of obligate lotic aquatic organisms whose life cycle includes
an aquatic phase of at least two months;

( ) “Obligate lotic aquatic organisms” means organisms that require
flowing water for all or almost all of the aquatic phase of their life cycles;

( ) “Stream” means a surface water that is not a wet weather conveyance;

( ) “Watercourse” means a man-made or natural hydrologic feature with a
defined linear channel which discretely conveys flowing water, as opposed to
sheet-flow;

Macroinvertebrate Collection and Analysis | Aquatic Assessments

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
dislodged organisms.
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
organisms.
2. Material is emptied into a wash bucket, rinsed, inspected for organisms, and
discarded.

D. Justicia americana (water willow) Beds
1. These are sampled by working the net through a 1m section in a jabbing
motion.
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
discarded.

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
forceps.”

After the samples have been processed our aquatic entomologists identify each organism and provide an analysis of the results.

Stream & Wetland Mitigation Monitoring

Section 404 Clean Water Act Mitigation compliance documentation can be very difficult due to the complexity and detail of many permit conditions. In recent years we have implemented the deployment of our EcoDrones. This technology allows us to provide high resolution aerial imagery and gives our clients the data they need to make decisions and identify potential adaptive management areas or allows to display their stream & wetland mitigation monitoring and construction efforts for marketing purposes.

Biological Systems Consultants specializes in regulatory compliance assistance and has been monitoring sites in multiple states for many years. Achievement of mitigation goals and objectives for stream restoration, stream enhancement, stream creation, and stream preservation projects has been our goal for years, with the final goal always being release of liability from the monitoring program. Biological Systems Consultants has been able to achieve these goals for their clients. Biological Systems Consultants’ stream mitigation compliance team is equipped to take on all of your mitigation compliance needs (baseline studies, during, post). Our staff is fully permitted and qualified to conduct stream and wetland mitigation surveys and has extensive experience with various habitat assessment protocols. See more about stream restoration services here or if you have any questions about your Section 404, 401 or other mitigation compliance Contact us or request a quote today.

Section 7 ESA Consultation

Section 7 ESA consultation is required for projects to identify whether any proposed or listed species are located within a given area of a proposed action. The U.S. Fish and Wildlife Service (FWS) requires project review information to meet the requirements of Section 7(c) of the Endangered Species Act (EA) of 1973, as amended (16 U.S.C. 1531 et seq.). Potential direct, indirect, and cumulative effects to federally lusted species or their critical habitat must be considered during the evaluation. Migratory birds  must also be considered during these evaluations under the Migratory Bird Treaty Act (MBTA) and the Bald Eagle and Golden Eagle Protection Act (BGEPA). Non-federal type projects are not subject to Section 7, however, Section 9 of the Act may prohibit certain activities that may affect federally listed species. For an evaluation and consultation of your project please contact us or request a quote today. See additional services here.

Drone ESA Assessment Section 7

 

According to the USFWS website (www.fws.gov) the following provides a brief description of Section 7 ESA Consultation for informal and formal consultations:

Informal Section 7 ESA Consultation

Under Section 7, Federal agencies must consult with the U.S. Fish and Wildlife Service (Service) when any action the agency carries out, funds, or authorizes (such as through a permit) may affect a listed endangered or threatened species. This process usually begins as informal consultation. A Federal agency, in the early stages of project planning, approaches the Service and requests informal consultation. Discussions between the two agencies may include what types of listed species may occur in the proposed action area, and what effect the proposed action may have on those species.

If the Federal agency, after discussions with the Service, determines that the proposed action is not likely to affect any listed species in the project area, and if the Service concurs, the informal consultation is complete and the proposed project moves ahead. If it appears that the agency’s action may affect a listed species, that agency may then prepare a biological assessment to assist in its determination of the project’s effect on a species.

 Formal Section 7 ESA Consultation and the Biological Opinion

When a Federal agency determines, through a biological assessment or other review, that its action is likely to adversely affect a listed species, the agency submits to the Service a request for formal consultation. During formal consultation, the Service and the agency share information about the proposed project and the species likely to be affected. Formal consultation may last up to 90 days, after which the Service will prepare a biological opinion on whether the proposed activity will jeopardize the continued existence of a listed species. The Service has 45 days after completion of formal consultation to write the opinion.

In making a determination on whether an action will result in jeopardy, the Service begins by looking at the current status of the species, or “baseline.” Added to the baseline are the various effects – direct, indirect, interrelated, and interdependent – of the proposed Federal action. The Service also examines the cumulative effects of other non-Federal actions that may occur in the action area, including state, tribal, local, or private activities that are reasonably certain to occur in the project area.
