SUMMARY: The Tennessee Valley 

Authority (TVA) is publishing a final 

rule to amend its regulations that govern 

floating cabins located on the Tennessee 

River System. 

DATES: This final rule is effective

Drive, WT 11A–K, Knoxville, TN 37902. 

SUPPLEMENTARY INFORMATION: 

Legal Authority 

This final rule is promulgated under 

the authority of the TVA Act, as 

amended, 16 U.S.C. 831 et seq. and 

OMB Circular No. A–25. Under Section 

26a of the TVA Act, no obstructions 

affecting navigation, flood control, or 

public lands or reservations shall be 

constructed, operated, or maintained 

across, along, or in the Tennessee River 

System without TVA’s approval. TVA 

has long considered nonnavigable 

structures such as floating cabins to be 

obstructions that require its approval. In 

addition, Section 9b of the TVA Act (16 

U.S.C. 831h–3) provides that TVA may 

require floating cabins to be maintained 

by the owner to reasonable health, 

safety, and environmental standards. 

Background 

TVA is a multi-purpose federal 

agency that has been charged by 

Congress with promoting the wise use 

and conservation of the resources of the 

Tennessee Valley region, including the 

Tennessee River System. In carrying out 

this mission, TVA operates a system of 

dams and reservoirs on the Tennessee 

River and its tributaries for the purposes 

of navigation, flood control, and power 

production. Consistent with those 

purposes, TVA uses the system to 

improve water quality and water supply 

and to provide a wide range of public 

benefits including recreation. 

To promote the unified development 

and regulation of the Tennessee River 

System, Congress directed TVA to 

approve obstructions across, along, or in 

the river system under Section 26a of 

the TVA Act. ‘‘Obstruction’’ is a broad 

term that includes, by way of example, 

boat docks, piers, boathouses, buoys, 

floats, boat launching ramps, fills, water 

intakes, devices for discharging 

effluents, bridges, aerial cables, culverts, 

pipelines, fish attractors, shoreline 

stabilization projects, channel 

excavations, and floating cabins. TVA 

also owns, as agent for the United 

States, much of the shoreland and 

inundated land along and under its 

reservoir system. 

Since 1971, TVA has used its Section 

26a authority to prohibit the mooring on 

the Tennessee River System of new 

floating cabins (formerly nonnavigable 

houseboats) that are designed and used 

primarily for habitation and not for 

water transportation. In particular, TVA 

amended its regulations in 1971 to 

prohibit the mooring or anchoring of 

new nonnavigable houseboats except for 

those in existence before November 21, 

1971. Since 1971, TVA has made minor 

changes to its regulations affecting 

nonnavigable houseboats, including in 

1978 when TVA prohibited mooring of 

nonnavigable houseboats on the 

Tennessee River System except for those 

in existence on or before February 15, 

1978. Effective October 1, 2018, TVA 

updated its regulations to change the 

terminology to floating cabins (rather 

than nonnavigable houseboats) and 

prohibit new floating cabins that did not 

exist on the Tennessee River System on 

or before December 16, 2016. 

Despite over 40 years of regulation 

related to floating cabins, the number of 

floating cabins on the Tennessee River 

System continued to increase. In 

determining what action to take with 

respect to floating cabins, TVA prepared 

an Environmental Impact Statement 

(EIS) in accordance with the National 

Environmental Policy Act. This EIS 

assessed the environmental and 

socioeconomic impacts of different 

policies to address the proliferation of 

floating cabins on the Tennessee River 

System. TVA released a draft of this EIS 

for public comment in June 2015 and 

held four public meetings and a webinar 

to provide information about its 

analyses and to facilitate public 

involvement. The final EIS and 

associated documents can be found at 

https://www.tva.com/floatingcabins. 

After considering the comments 

received during the EIS process and the 

analyses of impacts, TVA identified as 

its preferred policy one that establishes 

standards to ensure safer mooring, 

electrical connections, and protection of 

water quality. Under the preferred 

policy, the mooring of new floating 

cabins would be prohibited on the 

Tennessee River System. The preferred 

policy would have required all existing 

floating cabins, including nonnavigable 

houseboats, to be removed from the 

Tennessee River System by January 1, 

2036, and be subject to a regulatory 

program in the interim. On May 5, 2016, 

the TVA Board of Directors adopted the 

preferred policy, except the Board 

extended the removal date to May 5, 

2046. 

On December 16, 2016, Congress 

enacted the Water Infrastructure 

Improvements for the Nation Act of 

2016 (WIIN Act). Section 5003 related to 

floating cabins and amended the TVA 

Act to include Section 9b (16 U.S.C. 

831h–3). This new section of the TVA 

Act provides that TVA may approve and 

allow the use of floating cabins on 

waters under the jurisdiction of TVA as 

of December 16, 2016, if the floating 

cabin is maintained to reasonable 

health, safety, and environmental 

standards as required by the TVA Board 

of Directors and if the owner pays a 

compliance fee if assessed by TVA. The 

WIIN Act stipulates that TVA may not 

require the removal of a floating cabin 

that was located on the Tennessee River 

System as of December 16, 2016: (1) for 

a period of 15 years if it was granted a 

permit by TVA before enactment, or (2) 

for a period of 5 years if it was not 

granted a permit by TVA before 

enactment. It further stipulates that TVA 


ddrumheller on DSK120RN23PROD with RULES1
Federal Register / Vol. 89, No. 247 / Thursday, December 26, 2024 / Rules and Regulations 104879 

may establish regulations to prevent the 

construction of new floating cabins. 

Previous Floating Cabins Amendments 

to TVA’s Section 26a Regulations 

TVA published ‘‘Phase I’’ rule 

amendments for floating cabins that 

became effective on October 1, 2018. 

These amendments clarified the types of 

structures that TVA will regulate as a 

floating cabin and prohibited new 

floating cabins from mooring on the 

Tennessee River System after December 

16, 2016. TVA estimates that 

approximately 2,200 floating cabins 

were moored on the Tennessee River 

System on December 16, 2016. 

TVA published ‘‘Phase II’’ rule 

amendments for floating cabins that 

became effective on October 12, 2021. 

These amendments included health, 

safety, environmental, and permitting 

standards that apply to all floating 

cabins and a deadline by which floating 

cabin owners were to apply to TVA for 

a Section 26a permit. A diverse 

stakeholder group composed of 18 

members advised TVA on the 

development and drafting of these 

standards. Owners of floating cabins 

were given until October 1, 2024, to 

comply with the standards in TVA’s 

regulations and submit a complete 

permit application that certifies 

compliance and includes the payment 

of a Section 26a permit application fee. 

The permit application submission date 

of October 1, 2024, gave owners 

approximately three years from the 

effective date of the new standards to 

bring structures into compliance. 

Final Rule 

The final rule for floating cabins 

applies to all existing floating cabins, 

including those formerly referred to as 

nonnavigable houseboats originally 

permitted on or before February 15, 

1978. All floating cabins and attached 

structures must comply with the 

standards in TVA’s regulations and 

submit a complete Section 26a permit 

application that certifies compliance 

and includes the payment of a permit 

application fee by October 1, 2029. TVA 

will not require floating cabin owners to 

pay the initial permit application fee if 

they possess a permit in their name 

issued before December 16, 2016, and 

the structure is compliant with the 

terms of the permit, constructed in 

accordance with the permit (same 

dimensions, attached structures such as 

docks, and utility connections), and 

moored at the permitted location. 

TVA’s Section 26a regulations 

previously required floating cabins to 

comply with the standards and apply 

for a new permit by October 1, 2024. 

This final rule extends that time until 

October 1, 2029. TVA has encouraged 

floating cabin owners to bring floating 

cabins into compliance and then apply 

for a permit without delay. TVA may 

deny an initial application for a floating 

cabin if it is submitted after the deadline 

of October 1, 2029. 

Upon submission of the application, 

owners of floating cabins may remain in 

place until TVA acts on the application. 

If TVA approves the application, TVA 

will issue a Section 26a permit to the 

owner. If TVA denies the application, 

the owner must remove the structure in 

accordance with Section 9b of the TVA 

Act and 18 CFR 1304.406. 

Rebuilding 

This final rule also clarifies language 

on rebuilding floating cabins. Any 

alterations to the dimensions or 

approved plans for an existing floating 

cabin (monolithic frame or attached 

structure) are deemed a structural 

modification and require written 

approval from TVA. 

Electrical 

Floating cabins can pose a threat to 

public safety due to unsafe electrical 

systems. TVA is aware that floating 

cabins are currently obtaining electricity 

from the shore via underwater cables, 

through onboard portable generators, 

and by other methods. When the final 

Phase II rule on floating cabins was 

published in 2021, TVA was not aware 

of any local, state, or federal entity that 

monitored the construction of floating 

cabins and enforced building codes. 

However, after working with multiple 

state agencies, it became clear that state 

and local entities have the ability and 

expertise to regulate and inspect 

electrical requirements for floating 

cabins within their jurisdiction. 

Separate standards in TVA’s Section 26a 

regulations have potential to create 

confusion for floating cabin owners 

about applicable requirements. 

This final rule does not change the 

requirement that floating cabin owners 

comply with all applicable federal, 

state, and local laws and regulations 

regarding electrical wiring and 

equipment. If a floating cabin is 

documented to be in violation of any 

federal, state, or local electrical standard 

or regulation by the respective 

regulatory agency, TVA may revoke the 

permit and require removal of the 

floating cabin from the Tennessee River 

System if the violation is not corrected 

as specified by the relevant regulatory 

agency in accordance with the agency’s 

requirements. The final rule removes 

the separate electrical standards for 

floating cabins from the Section 26a 

regulations and removes the 

requirement that floating cabin owners 

submit a certification of compliance to 

TVA every even-numbered year. This 

appropriately recognizes that state and 

local agencies are best equipped to 

adopt and enforce electrical standards 

for floating cabins while reinforcing that 

compliance with those other agency 

standards is a condition of the Section 

26a permit. This final rule also clarifies 

that applicants must provide 

documentation, upon TVA’s request, 

that demonstrates the floating cabin is 

in compliance with applicable 

wastewater and electric standards. In 

the event that a floating cabin owner 

fails to provide satisfactory evidence of 

compliance upon request, TVA may 

revoke the Section 26a permit and 

require removal of the floating cabin 

from the reservoir. 

Other Changes to Section 26a 

Regulations 

In addition to the changes affecting 

floating cabins listed above, this final 

rule provides other minor amendments 

to the Section 26a regulations. These 

include minor edits for clarity and 

consistency in the regulations. This 

includes a clarification that TVA’s 

issuance of a Section 26a permit for any 

proposed facility or obstruction does not 

mean the proposed facility or 

obstruction has been deemed safe by 

TVA. TVA is also clarifying that TVA 

may proceed with the review of a 

Section 26a application absent the 

submission of some of the application 

materials identified in 18 CFR 1304.2. 

Comments on the Proposed Rule and 

TVA’s Responses 

TVA published the proposed rule for 

public review and comment in the 

Federal Register on August 29, 2024 (89 

FR 70145). TVA received six comments 

during the public review period, all via 

email, from six individuals. Only three 

of the comments provided input on the 

proposed rule. The other three 

comments posed questions about 

individual floating cabins. The 

following discussion describes a 

summary of the comments received and 

provides TVA’s response to the 

comments. TVA appreciates the 

perspectives, interests, and concerns 

expressed by all commenters. After 

careful consideration of all comments 

received, TVA is finalizing the rule as 

proposed. 

1. Comment Related to Wastewater 

Comment: One commenter stated that 

graywater discharge was not included in 

the regulations and referenced rumors 


ddrumheller on DSK120RN23PROD with RULES1
104880 Federal Register / Vol. 89, No. 247 / Thursday, December 26, 2024 / Rules and Regulations 

about only the discharge of untreated 

sewage being prohibited. 

TVA Response: Discharges of 

blackwater and graywater are regulated 

by the EPA and the state agencies that 

are responsible for issuing National 

Pollutant Discharge Elimination System 

permits for facilities that discharge 

sewage or other wastewater. Pursuant to 

Section 401 of the Clean Water Act, if 

a structure or activity for which federal 

approval is sought may result in any 

discharge into navigable waters of the 

United States, then the applicant must 

also request certification from the 

relevant state certifying agency when 

applying for a Section 26a permit. If the 

certifying agency denies certification on 

appropriate grounds, TVA will not be 

able to issue the Section 26a permit. If 

the certifying agency grants certification 

with appropriate conditions, those 

conditions are required to be 

incorporated in the Section 26a permit. 

If the conditions of that certification are 

violated or TVA is notified of an 

unresolved violation by one of these 

regulatory agencies, TVA is authorized 

to revoke the Section 26a permit and 

require removal of the floating cabin in 

compliance with the WIIN Act. 

2. Comment Related to the Sunset 

Period in the TVA Board Policy, WIIN 

Act, and Flotation Deadline 

Comment: One commenter expressed 

concern about the extension as it relates 

to the original TVA Board of Directors 

(Board) Policy sunset date of May 15, 

2046, the section of the WIIN Act that 

addresses removal of floating cabins, 

and the December 31, 2031, deadline to 

remove unencased flotation. There 

appears to be confusion around these 

deadlines. 

TVA Response: There are several 

different dates that are relevant to 

maintaining floating cabins on the 

Tennessee River System based on the 

TVA Act and TVA’s Section 26a 

regulations. On May 5, 2016, the TVA 

Board adopted a policy that would have 

required all existing floating cabins to 

be removed from the Tennessee River 

System by May 5, 2046 (sunset period). 

On December 16, 2016, Congress 

enacted the Water Infrastructure 

Improvements for the Nation Act of 

2016 (WIIN Act), which related to 

floating cabins and amended the TVA 

Act to include Section 9b. This new 

section of the TVA Act removed the 30- 

year sunset period and provided that 

floating cabins that were located on 

waters under the jurisdiction of TVA as 

of December 16, 2016, may remain if the 

floating cabin is maintained to 

reasonable health, safety, and 

environmental standards as required by 

TVA. The WIIN Act further stipulated 

that TVA may not require the removal 

of a floating cabin that was located on 

the Tennessee River System as of 

December 16, 2016: (1) for a period of 

15 years if it was granted a permit by 

TVA before the WIIN Act’s enactment, 

or (2) for a period of five years if it was 

not granted a permit by TVA before the 

WIIN Act’s enactment. 

TVA’s Section 26a regulations include 

a deadline of December 31, 2031, when 

all unencased flotation must be removed 

and replaced with flotation 

commercially manufactured for marine 

use and consistent with standards 

defined in the regulations. This 

requirement applies to all water-use 

facilities permitted by TVA, including 

floating cabins. 

This final rule requires floating cabin 

owners to comply with the regulations 

and apply for a permit no later than 

October 1, 2029. Any permit issued will 

be contingent upon compliance with the 

flotation rule by December 31, 2031. 

The Board sunset period no longer 

applies. The WIIN Act removal date for 

floating cabins that were not granted a 

permit before the WIIN Act has already 

passed; TVA may not require the 

removal of previously permitted floating 

cabins until December 16, 2031. 

3. Comments in Support of the Final 

Rule 

Comment: Two commenters 

expressed general support for the final 

rule amendments, particularly the 

extension of the compliance and 

application deadline. 

TVA Response: TVA acknowledges 

these comments and agrees with the 

need for the extension and to avoid 

confusion around electrical 

requirements. 

4. Questions About Floating Cabins 

Comment: Three commenters posed 

questions about the proposal, including 

questions on individual floating cabins 

and the corresponding deadlines for 

electrical standards. 

TVA Response: Questions about 

individual floating cabins and 

compliance may be directed to TVA at 

fh@tva.gov. 

Administrative Requirements 

A. Unfunded Mandates Reform Act, 

National Environmental Policy Act, and 

Various Executive Orders Including E.O.

Modernizing Regulatory Review 

In determining what action to take 

with respect to floating cabins, TVA 

prepared an Environmental Impact 

Statement (EIS) in accordance with the 

National Environmental Policy Act. 

This EIS assessed the environmental 

and socioeconomic impacts of different 

policies to address the proliferation of 

floating cabins on the Tennessee River 

System. TVA released a draft of this EIS 

for public comment in June 2015 and 

held four public meetings and a webinar 

to provide information about its 

analyses and to facilitate public 

involvement. The final EIS and 

associated documents can be found at 

https://www.tva.com/floatingcabins. 

This final rule contains no federal 

mandates for state, local, or tribal 

government or for the private sector. 

TVA has determined it will not have a 

significant annual effect of $200 million 

or more or result in expenditures of 

$200 million in any one year by state, 

local, or tribal governments or by the 

private sector. This final rule will not 

have a substantial direct effect on the 

States or Indian tribes, on the 

relationship between the Federal 

Government and the States or Indian 

tribes, or on the distribution of power 

and responsibilities between the Federal 

Government and States or Indian tribes. 

Nor will this final rule have concerns 

for environmental health or safety risks 

that may disproportionately affect 

children, have significant effect on the 

supply, distribution, or use of energy, or 

disproportionally impact low-income or 

minority populations. Unified 

development and regulation of the 

Tennessee River System through an 

approval process for obstructions across, 

along, or in the river system and 

management of United States-owned 

land entrusted to TVA are federal 

functions for which TVA is responsible 

under the TVA Act, as amended. In 

general, this final rule updates TVA’s 

regulations relating to the standards that 


ddrumheller on DSK120RN23PROD with RULES1
Federal Register / Vol. 89, No. 247 / Thursday, December 26, 2024 / Rules and Regulations 104881 

floating cabins will be required to meet 

in order to remain on the Tennessee 

River System. Absent a request for these 

services for a Section 26a permit, no 

entity or individual would be forced to 

pay a charge. None of the charges would 

be applied retroactively. TVA will 

continue to appropriately review 

specific requests in accordance with 

applicable laws, regulations, and 

Executive Orders. 

B. Regulatory Flexibility Act 

Under the Regulatory Flexibility Act, 

5 U.S.C. 605, TVA is required to prepare 

a regulatory flexibility analysis unless 

the head of the agency certifies that the 

proposal will not have a significant 

economic impact on a substantial 

number of small entities. TVA’s Chief 

Executive Officer has certified that this 

rule will not have a significant 

economic impact on a substantial 

number of small entities. The statute 

defines ‘‘small entity’’ as a ‘‘small 

business,’’ ‘‘small organization’’ (further 

defined as a ‘‘not-for-profit enterprise’’), 

or a ‘‘small governmental jurisdiction.’’ 

Most floating cabins are owned by 

individuals and not businesses, not-forprofit enterprises, or small 

governmental jurisdictions, and 

therefore relatively few ‘‘small entities’’ 

will be affected by TVA’s proposal. 

Even if the final rule tangentially 

impacts marinas that accommodate 

floating cabins, a relatively small 

number of marinas will be impacted. 

Accordingly, this rule will not have a 

significant impact on a substantial 

number of small entities; no regulatory 

flexibility analysis is required; and 

TVA’s Chief Executive Officer has made 

the requisite certification. 

C. Paperwork Reduction Act 

Title of Information Collection: 

Section 26a Permit Application. 

OMB Approval Number: 3316–0060. 

This rule contains information 

collection requirements for registration 

and permitting of floating cabins, which 

were approved by the Office of 

Management and Budget (OMB) on July 

31, 2024.

[Docket Number USCG–2024–1078] 

RIN 1625–AA87 

Security Zone; Corpus Christi Ship 

Channel, Corpus Christi, TX 

AGENCY: Coast Guard, DHS. 

ACTION: Temporary final rule. 

SUMMARY: The Coast Guard is 

establishing a temporary moving 

security zone for navigable waters 

within a 500-yard radius of certain 

vessels carrying cargo requiring an 

elevated level of security in the Corpus 

Christi Ship Channel. The temporary 

security zone is needed to protect the 

vessels, the cargo, and the surrounding 

waterway from terrorist acts, sabotage, 

or other subversive acts, accidents, or 

events of a similar nature. Entry of 

vessels or persons into this zone is 

prohibited unless specifically 

authorized by the Captain of the Port, 

Sector Corpus Christi or a designated 

representative. 

DATES: For the purposes of enforcement, 

actual notice will be used from 

December 20, 2024, until December 26, 

2024. This rule is effective without 

actual notice from December 26, 2024 

until December 27, 2024.

NPRM Notice of proposed rulemaking 

§ Section 

U.S.C. United States Code 

II. Background Information and 

Regulatory History 

The Coast Guard is issuing this 

temporary rule under the authority in 5 

U.S.C. 553(b)(B). This provision 

authorizes an agency to issue a rule 

without prior notice and opportunity to 

comment when the agency for good 

cause finds that those procedures are 

‘‘impracticable, unnecessary, or contrary 

to the public interest.’’ Under 5 U.S.C. 

553(b)(B), the Coast Guard finds that 

good cause exists for not publishing a 

notice of proposed rulemaking (NPRM) 

with respect to this rule because it is 

impracticable. The Coast Guard was 

notified of these vessels’ transit and 

cargo on December 12, 2024. There is 

insufficient time to publish an NPRM 

before this operation because the 

security zone must be established by 

December 20, 2024, to ensure security of 

the vessels and the surrounding area 

and there is insufficient time to provide 

a reasonable comment period and to 

consider those comments before issuing 

the rule. 

Under 5 U.S.C. 553(d)(3), the Coast 

Guard also finds that good cause exists 

for making this rule effective less than 

30 days after publication in the Federal 

Register. Delaying the effective date of 

this rule would be contrary to the public 

interest because quick action is needed 

to provide for the security of this vessel 

and its surroundings while it is in 

transit. 

III. Legal Authority and Need for Rule 

The Coast Guard is issuing this 

security zone regulation under the 

authority in 46 U.S.C. 70051 and 70124. 

The Captain of the Port, Sector Corpus 

Christi (COTP) has determined that 

potential hazards are associated with 

the transit of the Motor Vessel (M/V) 

ARC INDEPENDENCE. There is a 

security concern within a 500-yard 

radius of the vessel when it’s loaded 

and transiting while loaded. This rule is 

needed to provide for the safety and 

security of the vessel, its cargo, and the 

surrounding waterway from terrorist 

acts, sabotage, or other subversive acts, 

accidents, or other events of a similar 

nature while the vessel is transiting 

within Corpus Christi, TX. 

IV. Discussion of the Rule 

The Coast Guard is establishing a 500- 

yard radius, temporary, moving security 

zone around M/V ARC 

INDEPENDENCE. Other mariners and 

vessels will be able to identify the 

security zone because the M/V ARC 

INDEPENDENCE’s name is clearly 

marked on its stern, and port and 

starboard sides. The zone for the vessel 

will be effective from December 20, 

2024, through December 27, 2024, and 

will be enforced when the vessel is 

loaded and transiting the Corpus Christi 

Ship Channel. The security zone will be
