§ 1304.400 Flotation devices and material, all floating structures
(a) All flotation for docks, boat mooring buoys, and other water-use structures and facilities, shall be of materials commercially manufactured for marine use. Flotation materials shall be fabricated so as not to become water-logged, crack, peel, fragment, or be subject to loss of beads. Flotation materials shall be resistant to puncture, penetration, damage by animals, and fire. Any flotation within 40 feet of a line carrying fuel shall be 100 percent impervious to water and fuel. Styrofoam floatation must be fully encased. Reuse of plastic, metal, or other previously used drums or containers for encasement or flotation purpose is prohibited, except as provided in paragraph (c) of this section for certain metal drums already in use. Existing flotation (secured in place prior to September 8, 2003) in compliance with previous rules is authorized until in TVA’s judgment the flotation is no longer serviceable, at which time it shall be replaced with approved flotation upon notification from TVA. For any float installed after September 8, 2003, repair or replacement is required when it no longer performs its designated function or exhibits any of the conditions prohibited by this subpart.

(b) Because of the possible release of toxic or polluting substances, and the hazard to navigation from metal drums that become partially filled with water and escape from docks, boathouses, houseboats, floats, and other water-use structures and facilities for which they are used for flotation, the use of metal drums in any form, except as authorized in paragraph (c) of this section, for flotation of any facilities is prohibited.

(c) Only metal drums which have been filled with plastic foam or other solid flotation materials and welded, strapped, or otherwise firmly secured in place prior to July 1, 1972, on existing facilities are permitted. Replacement of any metal drum flotation permitted to be used by this paragraph must be with a commercially manufactured flotation device or material specifically designed for marine applications (for example, pontoons, boat hulls, or other buoyancy devices made of steel, aluminum, fiberglass, or plastic foam, as provided for in paragraph (a) of this section).

(d) Every flotation device employed in the Tennessee River system must be firmly and securely affixed to the structure it supports with materials capable of withstanding prolonged exposure to wave wash and weather conditions.

§ 1304.402 Wastewater outfalls
Applicants for a wastewater outfall shall provide copies of all federal, state, and local permits, licenses, and approvals required for the facility prior to applying for TVA approval, or shall concurrently with the TVA application apply for such approvals. A section 26a permit shall not be issued until other required water quality approvals are obtained, and TVA reserves the right to impose additional requirements.

§ 1304.403 Marina sewage pump-out stations and holding tanks
All pump-out facilities constructed after September 8, 2003, shall meet the following minimum design and operating requirements:

(a) Spill-proof connection with shipboard holding tanks;

(b) Suction controls or vacuum breaker capable of limiting suction to such levels as will avoid collapse of rigid holding tanks;

(c) Available fresh water facilities for tank flushing;

(d) Check valve and positive cut-off or other device to preclude spillage when breaking connection with vessel being severed;

(e) Adequate interim storage where storage is necessary before transfer to approved treatment facilities;

(f) No overflow outlet capable of discharging effluent into the reservoir;

(g) Alarm system adequate to notify the operator when the holding tank is full;

(h) Convenient access to holding tanks and piping system for purposes of inspection;

(i) Spill-proof features adequate for transfer of sewage from all movable floating pump-out facilities to shore-based treatment plants or intermediate transfer facilities;

(j) A reliable disposal method consisting of:
(1) An approved upland septic system that meets TVA, State, and local requirements; or
(2) Proof of a contract with a sewage disposal contractor; and

(k) A written statement to TVA certifying that the system shall be operated and maintained in such a way as to prevent any discharge or seepage of wastewater or sewage into the reservoir.

§ 1304.404 Commercial marina harbor limits
The landward limits of commercial marina harbor areas are determined by the extent of land rights held by the dock operator. The lakeward limits of harbors at commercial marinas will be designated by TVA on the basis of the size and extent of facilities at the dock, navigation and flood control requirements, optimum use of lands and land rights owned by the United States, carrying capacity of the reservoir area in the vicinity of the marina, and on the basis of the environmental effects associated with the use of the harbor. Mooring buoys, slips, breakwaters, and permanent anchoring are prohibited beyond the lakeward extent of harbor limits. TVA may, at its discretion, reconfigure harbor limits based on changes in circumstances, including but not limited to, changes in the ownership of the land base supporting the marina.

§ 1304.405 Fuel storage tanks and handling facilities
Fuel storage tanks and handling facilities are generally either underground (UST) or aboveground (AST) storage tank systems. An UST is any one or combination of tanks or tank systems defined in applicable federal or state regulations as an UST. Typically (unless otherwise provided by applicable federal or state rules), an UST is used to contain a regulated substance (such as a petroleum product) and has 10 percent or more of its total volume beneath the surface of the ground. The total volume includes any piping used in the system. An UST may be a buried tank, or an aboveground tank with buried piping if the piping holds 10 percent or more of the total system volume including the tank. For purposes of this part, an aboveground storage tank (AST) is any storage tank whose total volume (piping and tank) is less than 10 percent underground or any storage tank defined by applicable law or regulation as an AST.

(a) TVA requires the following to be included in all applications submitted after September 8, 2003, to install an UST or any part of an UST system below the 500-year flood elevation on a TVA reservoir, or regulated tailwater:
(1) A copy of the state approval for the UST along with a copy of the application sent to the state and any plans or drawings that were submitted for the state’s review;
(2) Evidence of secondary containment for all piping or other systems associated with the UST;
(3) Evidence of secondary containment to contain leaks from gas pumps(s);
(4) Calculations certified by a licensed, professional engineer in the relevant state showing how the tank will be anchored so that it does not float during flooding; and
(5) Evidence, where applicable, that the applicant has complied with all spill prevention, control and countermeasures (SPCC) requirements.

(b) The applicant must accept and sign a document stating that the applicant shall at all times be the owner of the UST system, that TVA shall have the right (but no duty) to prevent or remedy pollution or violations of law, including removal of the UST system, with costs charged to the applicant, that the applicant shall at all times maintain and operate the UST system in full compliance with applicable federal, state, and local UST regulations, and that the applicant shall maintain eligibility in any applicable state trust fund.

(c) An application to install an AST or any part of an AST system below the 500-year elevation on a TVA reservoir or a regulated tailwater is subject to all of the requirements of §1304.405 (a) and (b) except that paragraph (a)(1) shall not apply in states that do not require application or approval for installation of an AST. Eligibility must be maintained for any applicable AST trust fund, and the system must be maintained and operated in accordance with any applicable AST regulations. The applicant must notify and obtain any required documents or permission from the state fire marshal’s office prior to installation of the AST. The applicant must also follow the National Fire Protection Association Codes 30 and 30A for installation and maintenance of flammable and combustible liquids storage tanks at marine service stations.

(d) Fuel handling on private, non-commercial docks and piers. TVA will not approve the installation, operation, or maintenance of fuel handling facilities on any private, non-commercial dock or pier.

(e) Floating fuel handling facilities. TVA will not approve the installation of any floating fuel handling facility or fuel storage tank.

(f) Demonstration of financial responsibility. Applicants for a fuel handling facility to be located in whole or in part on TVA land shall be required to provide TVA, in a form and amount acceptable to TVA, a surety bond, irrevocable letter of credit, pollution liability insurance, or other evidence of financial responsibility in the event of a release.

§ 1304.406 Removal of unauthorized, unsafe, and derelict structures or facilities
If, at any time, any dock, wharf, boathouse (fixed or floating), nonnavigable houseboat, outfall, aerial cable, or other fixed or floating structure or facility (including any navigable boat or vessel that has become deteriorated and is a potential navigation hazard or impediment to flood control) is anchored, installed, constructed, or moored in a manner inconsistent with this part, or is not constructed in accordance with plans approved by TVA, or is not maintained or operated so as to remain in accordance with this part and such plans, or is not kept in a good state of repair and in good, safe, and substantial condition, and the owner or operator thereof fails to repair or remove such structure (or operate or maintain it in accordance with such plans) within ninety (90) days after written notice from TVA to do so, TVA may cancel any license, permit, or approval and remove such structure, and/or cause it to be removed, from the Tennessee River system and/or lands in the custody or control of TVA.

Such written notice may be given by mailing a copy thereof to the owner’s address as listed on the license, permit, or approval or by posting a copy on the structure or facility. TVA may remove or cause to be removed any such structure or facility anchored, installed, constructed, or moored without such license, permit, or approval, whether such license or approval has once been obtained and subsequently canceled, or whether it has never been obtained. TVA’s removal costs shall be charged to the owner of the structure, and payment of such costs shall be a condition of approval for any future facility proposed to serve the tract of land at issue or any tract derived therefrom whether or not the current owner caused such charges to be incurred.

In addition, any applicant with an outstanding removal charge payable to TVA shall, until such time as the charge be paid in full, be ineligible to receive a permit or approval from TVA for any facility located anywhere along or in the Tennessee River or its tributaries. TVA shall not be responsible for the loss of property associated with the removal of any such structure or facility including, without limitation, the loss of any navigable boat or vessel moored at such a facility. Any costs voluntarily incurred by TVA to protect and store such property shall be removal costs within the meaning of this section, and TVA may sell such property and apply the proceeds toward any and all of its removal costs. Small businesses seeking expedited consideration of the economic impact of actions under this section may contact TVA’s Supplier and Diverse Business Relations staff, TVA Procurement, 1101 Market Street, Chattanooga, Tennessee 37402-2801.

§ 1304.407 Development within flood control storage zones of TVA reservoirs
(a) Activities involving development within the flood control storage zone on TVA reservoirs will be reviewed to determine if the proposed activity qualifies as a repetitive action. Under TVA’s implementation of Executive Order 11988, Floodplain Management, repetitive actions are projects within a class of actions TVA has determined to be approvable without further review and documentation related to flood control storage, provided the loss of flood control storage caused by the project does not exceed one acre-foot. A partial list of repetitive actions includes:
(1) Private and public water-use facilities;
(2) Commercial recreation boat dock and water-use facilities;
(3) Water intake structures;
(4) Outfalls;
(5) Mooring and loading facilities for barge terminals;
(6) Minor grading and fills; and
(7) Bridges and culverts for pedestrian, highway, and railroad crossings.

(b) Projects resulting in flood storage loss in excess of one acre-foot will not be considered repetitive actions.

(c) For projects not qualifying as repetitive actions, the applicant shall be required, as appropriate, to evaluate alternatives to the placement of fill or the construction of a project within the flood control storage zone that would result in lost flood control storage. The alternative evaluation would either identify a better option or support and document that there is no reasonable alternative to the loss of flood control storage. If this determination can be made, the applicant must then demonstrate how the loss of flood control storage will be minimized.
(1) In addition, documentation shall be provided regarding

(i) The amount of anticipated flood control storage loss;
(ii) The cost of compensation of the displaced flood control storage (how much it would cost to excavate material from the flood control storage zone, haul it to an upland site and dispose of it);
(iii) The cost of mitigation of the displaced flood control storage (how much it would cost to excavate material from another site within the flood control storage zone, haul it to the project site and use as the fill material);
(iv) The cost of the project; and
(v) The nature and significance of any economic and/or natural resource benefits that would be realized as a result of the project.

(2) TVA may, in its discretion, decline to permit any project that would result in the loss of flood control storage.

(d) Recreational vehicles parked or placed within flood control storage zones of TVA reservoirs shall be deemed an obstruction affecting navigation, flood control, or public lands or reservations within the meaning of section 26a of the Act unless they:
(1) Remain truly mobile and ready for highway use. The unit must be on its wheels or a jacking system and be attached to its site by only quick disconnect type utilities;
(2) Have no permanently attached additions, connections, foundations, porches, or similar structures; and
(3) Have an electrical cutoff switch that is located above the flood control zone and fully accessible during flood events.

§ 1304.409 Indefinite or temporary moorage of recreational vessels
(a) Recreational vessels’ moorage at unpermitted locations along the water’s edge of any TVA reservoir may not exceed 14 consecutive days at any one place or at any place within one mile thereof.

(b) Recreational vessels may not establish temporary moorage within the limits of primary or secondary navigation channels.

(c) Moorage lines of recreational vessels may not be placed in such a way as to block or hinder boating access to any part of the reservoir.

(d) Permanent or extended moorage of a recreational vessel along the shoreline of any TVA reservoir without approval under section 26a of the TVA Act is prohibited.

§ 1304.410 Navigation restrictions
(a) Except for the placement of riprap along the shoreline, structures, land based or water use, shall not be located within the limits of safety harbors and landings established for commercial navigation.

(b) Structures shall not be located in such a way as to block the visibility of navigation aids. Examples of navigation aids are lights, dayboards, and directional signs.

(c) The establishment of “no-wake” zones outside approved harbor limits is prohibited at marinas or community dock facilities that are adjacent to or near a commercial navigation channel. In such circumstances, facility owners may, upon approval from TVA, install a floating breakwater along the harbor limit to reduce wave and wash action.

§ 1304.411 Fish attractors
Fish attractors constitute potential obstructions and require TVA approval.
(a) Fish attractors may be constructed of anchored brush piles, log cribs, and/or spawning benches, stake beds, vegetation, or rock piles, provided they meet “TVA Guidelines for Fish Attractor Placement in TVA Reservoirs” (TVA 1997).

(b) When established in connection with an approved dock, fish attractors shall not project more than 30 feet out from any portion of the dock.

(c) Any floatable materials must be permanently anchored.
