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;   Contact us or request a quote for your hydrologic determination...

Macroinvertebrate Collection and Analysis | Aquatic Assessments

Benthic Macroinvertebrates Aquatic Assessment Macroinvertebrate Survey 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...

NPDES BMP and SPCC Plans

NPDES Permit BMP and SPCC Plans The KPDES general coal permit states, “The permittee shall develop and implement a BMPP consistent with 401 KAR 5:065, Section 2(4) pursuant to KRS 224.70-110, which prevents or minimizes the potential for the release of “BMP pollutants” from ancillary activities through site runoff; spillage or leaks, sludge or waste disposal; or drainage from raw material storage. These conditions apply to all permittees who use, manufacture, store, handle, or discharge any pollutant listed as: (1) toxic under Section 307(a)(1) of the Clean Water Act; (2) oil, as defined in Section 311(a)(1) of the Act; (3) any pollutant listed as hazardous under Section 311 of the Act; or (4) is defined as a pollutant pursuant to KRS 224. 1-010(35) and who have operations which could result in (1) the release of a hazardous substance, pollutant, or contaminant, or (2) an environmental emergency, as defined in KRS 224.1-400, as amended, or any regulation promulgated pursuant thereto (hereinafter, the “BMP pollutants”). These operations include material storage areas; Plant site runoff; in-Plant transfer, process and material handling areas; loading and unloading operations, and sludge and waste disposal areas. The permittee shall implement the BMP Plan upon of the commencement of regulated activity. Modifications to the Plan as a result of ineffectiveness or Plan changes to the facility shall be implemented as soon as possible. Within 90 days of the effective date of the permit, the permittee shall evaluate the current BMP Plan and make any necessary modifications to insure its continued effectiveness. Contact us today if you would like one of these plans prepared for your site. To see a list of all of our services go here. Contact us or request a quote...
