§ 401 Water Quality Certification NRS16.166 Modification

PART I

Authorized Alterations

The authorized work includes excavation of approximately 98,000 cubic yards of material from the bed of Nickajack Reservoir (Tennessee River Mile 471.0), directly below Chickamauga Dam in Chattanooga, Tennessee. The excavation shall take place within an existing cofferdam structure directly adjacent to Chickamauga Lock. Activities associated with the excavation work consist of the following activities:

Secant Pile Wall- construction of a secant pile wall approximately 51’ x 2’ in size on the interior of the existing cofferdam to stabilize the structure before excavation;

Inclined Rock Anchors- installation of 44 inclined rock anchors for stability purposes within the interior of the cofferdam (anchors are 60-68 strand, ranging in length from 66’ to 102’ and have bond lengths of 39’ to 43’);

Exploratory Drilling- drilling of 71 exploratory holes within the cofferdam, up to approximately 70 feet below the bottom of the reservoir;

Rock Excavation- excavation of approximately 98,000 cubic yards of predominately limestone rock within the boundaries of the existing cofferdam (approximately 6.48 acres). The area within the cofferdam has been previously dewatered and excavated during previous construction activities. Mussels from the cofferdam were relocated prior to excavation in earlier construction efforts. Excavation may vary from a minimum depth of 5 feet to a maximum depth 32 feet within the cofferdam area depending on the required founding elevations of the new concrete lock structure and the potential presence of bentonite clay formations. The excavation will be carried down utilizing support measures such as rock bolts and shotcrete;

Disposal of Excavated Materials- Materials excavated from the cofferdam would be disposed of at a site consisting of approximately 4.5 acres of uplands and 0.03 acre of emergent wetlands. The site has been used for disposal materials from previous excavations from Chickamauga Lock. As part of the disposal activities, an existing toe drain for Chickamauga Dam would be either removed and replaced at the current location with a stronger pipe capable of withstanding the weight of increased fill material, or a supplemental drain would be constructed around the disposal area to a new outfall location. The pipe for the toe drain currently runs underneath the disposal area and empties into North Chickamauga Creek. Total impacts to waters of the State would involve the excavation of 98,000 cy of rock from approximately 6.48 acres of Nickajack Reservoir located within an existing cofferdam and the permanent fill of 0.03 acre of emergent wetlands at the proposed disposal site.

Construction of a New Lock- The new lock would be 110 foot x 600 foot lock chamber and is to be constructed inside of the existing cofferdam structure.

Special Conditions:

1. The permittee shall submit as-built drawings of record that reflect the “as-constructed” condition of all authorized alterations to waters of the state.

§ 401 Water Quality Certification

a. The drawings shall include sufficient information, including photographic documentation, to demonstrate conformance with the approved plans, specifications, and special conditions of this permit.

b. The report shall be submitted within 90 days of completion of the project.

PART III

Notice of Determination:

Concern The future connection of the North Chickamauga Park greenway to the Chattanooga River Walk, in addition to the natural resource values of the TVA's Big Ridge Small Wild Area, may potentially be compromised by the disposal of the excavated rock.

Determination Upland disposal of dredged material is generally beyond the authority of this water quality certification. However, the proposed disposal site was identified as a spoil area in both the 1996 Final Environmental Impact Statement for the project (TVA) and the 2002 Final Supplement Environmental Impact Statement (Corps). The site has already been disturbed by placement of excavated material from 2007 through 2010. The project would result in short-term aesthetic impacts to the immediate construction area but the placement area is proposed to be covered with topsoil and seeded with native vegetation in the final stages of lock construction to make the area more aesthetically pleasing.

Concern The placement of rubble fill may leave several acres of prime location dangerous and unsuited for any use.

Determination Upland disposal of dredged material is generally beyond the authority of this water quality certification. The Corps’ responds that the work would not result in placement

§ 401 Water Quality Certification of dredged materials into any undisturbed natural areas as the placement area has already been used for disposal of material during construction of the cofferdam. The areas surrounding the placement site are not suitable locations for building development as they are all owned and operated by the Tennessee Valley Authority (TVA) for the purposes of operating Chickamauga Lock and Dam.

Concern The hydrology of the wetlands adjacent to the disposal area may be negatively affected by the project.

Determination The wetland’s hydrology, either inflow or outflow, should not be affected by the disposal of material. The source of water or hydrology for the wetland is from the side opposite the disposal area, therefore the fill should not affect the wetlands hydrologic source.

The outlet flow from the wetland is to be avoided as well, therefore not affecting the wetland’s outflow.

Concern The excavated rock material may have some commercial value, thereby avoiding the necessity of disposal at the planned disposal site.

Determination Upland disposal of dredged material is generally beyond the authority of this water quality certification. The Corps’ responds that the proposed excavation and disposal associated with this project would be performed by a contractor. Although the disposal site was identified as the preferred alternative to placed dredged material, the contractor, in consultation with the Corps, would have the option to explore off-site locations to place the dredged material (including commercial vendor sites). These options would be continually evaluated throughout the life of the contract.

Concern There is a history of use of part of the disposal site as a firing range. Lead bullet contaminants may become so trapped by stone as to be unrecoverable for any future required site mitigation.

Determination The future use of the upland disposal site is generally beyond the authority of this water quality certification. However, based on available information, it appears that an area near the disposal site was used for firearms training/practice although the area was never formally designated as such. However, the target areas were located outside of the disposal site to the east.

§ 401 Water Quality Certification

Excavation Site: The location of the cofferdam maintenance is Nickajack Reservoir, an open water impoundment of the Tennessee River (mile 471.0) directly downstream of Chickamauga Dam. The construction area is within an existing cofferdam that has previously been excavated. The substrate consists of limestone bedrock with sparse amounts of rock and gravel that has accumulated since initial construction. Pictures of the lock floor after a dewatering event in 2012 are shown below.

Overview of cofferdam (dewatered)

Substrate in cofferdam

§ 401 Water Quality Certification

Disposal Site: The disposal area is a site approximately 4.5 acres in size and approximately 1,800’ northeast of Chickamauga Lock, near the left descending bank of North Chickamauga Creek. The disposal area was used up to 2012 during a previous excavation used to create the existing cofferdam area.

Chickamauga Lock Disposal Area Location Map

The site consists almost entirely of uplands, however the disposal area is bordered to the northeast by a forested wetland (WET-002), which discharges to an intermittent stream (STR- 001). STR-001 runs through the northern portion of the proposed disposal area for approximately 340 linear feet from east to west as shown in figures below. Based on previous records, the stream was created by changes in the diversion of water on the site from previous disposal activities. STR-001 begins from the drainage of WET-002 and flows across the disposal site into a riprapped ditch (approximately 106’) and then into a culvert (approximately 33’) before flowing off the site. One alternative under consideration (Alternative 2 – See Section 10; Figure 14), would use the entire disposal area, with the exception of the southwest corner to store excavated materials. However, under Alternative 1 (Preferred Alternative), impacts to WET-002 and STR-001 would be avoided by this project. In the photographs below, it is important to note that the blue line represents the contractor work area for disposal of excavated materials, not the fill area, which is further discussed in Section 10.

§ 401 Water Quality Certification

The disposal of excavated material from within the cofferdam would permanently fill WET-001 resulting in 0.03 acre permanent loss of emergent wetlands.

An existing toe drain for Chickamauga Dam currently runs underneath the disposal area and empties into North Chickamauga Creek. To avoid damages to the toe drain associated with the extra weight of additional fill material, two alternatives are being considered. Alternative 1 would excavate and replace the existing toe drain in place with a stronger pipe of the same diameter that will be able to support the additional overburden weight. Alt 1 would result in the excavation and fill of 0.03 acre of emergent wetlands (WET-001), the same wetlands proposed to be filled during disposal activities. Realignment of the toe drain is a second alternative being considered (Alt 2). The realignment would result in the addition of a pipe from an existing manhole south of the disposal area and would convey water into North Chickamauga Creek, approximately 450’ linear feet downstream of the current outfall. Under Alt 2, the current toe drain and outfall would be left in place to collect any seepage from the northwest portion of the property. Although a new outfall would be constructed, the route of the new toe drain pipe is proposed totally in uplands and no waters of the State would be altered, other than a new outfall, which would empty into North Chickamauga Creek.

Plan for new toe drain pipe and outfall (Alt 2 below)

§ 401 Water Quality Certification

Photograph of WET-001

The proposed excavation would take place within an existing cofferdam structure and would change the bottom elevation within the cofferdam to varying degrees depending on the required founding elevations of the new concrete lock structure and the potential presence of bentonite clay formations. The resulting condition of the river bed within the cofferdam would be a solid bedrock bottom, much like the existing substrate, with varying depths. There would be no functional loss from the baseline conditions in the excavation area.

In the disposal area, impacts to WET-002 and STR-001 would be avoided. A 15-foot buffer would be left around WET-002 to minimize any potential indirect effects from the surrounding disposal activities. Either a realignment or replacement of an existing toe drain would occur.

Approximately 0.03 acre of emergent wetland (WET-001) would be permanently filled beneath the excavated material. Although a minor loss of function associated with WET-001 would occur, the functional capacity of the wetland is poor given its position on the landscape, disturbed soils and lack of habitat for wildlife. Due to the small size of proposed wetland impacts and the limited functions provided by WET-001, no compensatory mitigation is proposed for the 0.03 acre impact.
