Animal Waste Disposal Laws in Tennessee: Manure, Carcasses, and CAFO Rules Explained

Tennessee treats a dead cow the same way it treats household trash: as solid waste that must be managed under state disposal rules, and it gives you as little as 48 hours to act. If you raise livestock, run a poultry operation, or manage a farm in Tennessee, the state’s animal waste disposal laws touch almost everything you do — from how you store manure to how quickly you bury or render a carcass.

These rules come from more than one agency, and they overlap with federal water quality standards, county health codes, and even local burn ordinances. This guide walks through what Tennessee actually requires for livestock waste and dead-animal disposal, who enforces it, and what happens if you get it wrong.

Important Note: This article explains general regulatory requirements for informational purposes and is not legal advice. Rules change, and county ordinances can add stricter requirements — confirm current standards with the Tennessee Department of Agriculture (TDA) or the Tennessee Department of Environment and Conservation (TDEC) before making disposal decisions.

What Tennessee Requires for Livestock Waste and Dead-Animal Disposal

The disposal of dead animals falls under the solid waste regulations outlined by TDEC. That single fact shapes almost every rule that follows: a dead steer, hog, or flock of chickens is legally solid waste, not simply farm debris you can leave in a field or haul to the curb.

On the manure side, Tennessee regulates livestock waste primarily through its animal feeding operation (AFO) rules, which define an “Animal Waste Management System” as any system used for the collection, storage, treatment, handling, transport, distribution, land application, or disposal of agricultural wastes, animal waste/wastewater, waste product, and dead animals generated by an AFO that meets or exceeds USDA-NRCS technical standards and guidelines. In other words, manure storage and dead-animal disposal are treated as part of the same regulatory system on farms large enough to qualify as an AFO.

Smaller operations, including backyard flocks, aren’t exempt from basic sanitation expectations either. If you’re weighing what’s allowed for a home coop, the backyard chicken laws in Tennessee cover manure and mortality handling at a smaller scale. Larger commercial and family farm operations, meanwhile, often fall under separate legal protections; see how those interact with waste rules in our breakdown of right-to-farm laws in Tennessee. Note that these agricultural rules are distinct from residential pet waste — Tennessee has no statewide pet-waste statute, a separate issue covered in our guide to dog leash laws in Tennessee.

Manure Storage, Stockpiling, and Land-Application Rules in Tennessee

Manure storage and field application are governed by Tennessee’s AFO rules under Chapter 0400-40-05, which set both design standards for storage structures and application limits for spreading manure on cropland. These rules apply once an operation meets the state’s definition of an animal feeding operation.

For land application, manure, litter, and process wastewater shall be applied no closer than 100 feet of any potable well, public or private, and AFOs located adjacent to exceptional Tennessee waters and outstanding national resource waters shall leave in place a minimum 60-foot natural riparian buffer between the stream and the land application area. A “setback” in this context is legally defined as a specified distance from surface waters or potential conduits to surface waters where manure, litter, and process wastewater may not be land-applied, including open tile line intake structures, sinkholes, and wells.

Application rates aren’t left to guesswork, either. Application rates for manure, litter, and other process wastewater must minimize phosphorus and nitrogen transport from the field to surface waters, using a field-specific assessment that employs the Tennessee Phosphorus Index. This tool, developed by University of Tennessee Extension and USDA-NRCS, determines how much manure a given field can safely absorb.

Small-scale stockpiling has more flexibility. TDEC rules exempt from permitting the disposal of farming wastes at facilities on the site of generation with a fill area of less than one acre when completed. That exemption is why most family farms can manage manure piles and composting areas without a state permit, provided they stay within that footprint and follow setback distances. If you’re expanding a flock or herd and storing more manure on-site, review the same backyard chicken laws in Tennessee guidance for coop and run sanitation standards that pair with these storage rules.

How You Must Dispose of Dead Livestock Carcasses in Tennessee

Timing matters most here. In Tennessee, dead animal carcasses need to be removed within 48 hours. That clock starts the moment the animal dies, regardless of cause, and it applies whether you’re dealing with a single cow or a barn’s worth of poultry.

Tennessee recognizes several lawful disposal methods, each with its own technical standard:

Method	Permit Required	Key Standard
On-farm burial	No, if under 1 acre	NRCS Practice Code 316; more than 2 feet above bedrock/water table
Composting	No	NRCS Conservation Practice Standard 317
Class I landfill	No	Accepted without written permission
Class II/III landfill	Yes	Requires written permission from TDEC Commissioner
Rendering	Varies by facility	Restrictions on cattle 30+ months old
Incineration	No, if under capacity limit	Under 500 lbs/hr or 400,000 Btu/hr, livestock/poultry only
Open burning	No, limited exemption	Only #1/#2 fuel oil, on-site vegetation, or wood waste

For burial, burial should conform to the recommendations of USDA-NRCS Practice Code 316, keeping the carcass more than two feet above bedrock and the ground water table. Composting follows a similar logic: it usually requires creating a two-foot base of woody by-products such as wood chips, sawdust, or wood shavings, then covering the dead animal with at least two more feet of the wood by-product.

Producers may dispose of deceased livestock in Class I landfills in Tennessee, while Class II and III landfills allow the disposal of dead animals only with written permission from the Commissioner of TDEC. Not every Class I facility will accept large animals in practice, so calling ahead is worthwhile before hauling a carcass any distance — a point that connects directly to how you may legally move livestock in the first place under Tennessee’s transporting livestock laws in Tennessee.

Open burning has a narrow legal window. Section 1200-3-4-.04 of TDEC’s Air Pollution Control Rules provides an exemption for fires solely for the burning of bodies of dead animals, including poultry, where no other safe and practical disposal method exists, and priming materials are limited to #1 or #2 grade fuel oils, vegetation grown on the property, and wood waste. Incineration has its own carve-out: livestock and poultry incinerators are exempt from air quality permitting if the unit’s rated capacity is under 500 pounds per hour or 400,000 Btu per hour, only carcasses are charged into the unit, and it isn’t a commercial operation.

Rendering remains legal but has shrunk in availability. Rendering companies may offer on-farm pickup of deceased livestock, but restrictions may apply for dead cows 30 months of age or older because of federal BSE-related feed rules. For mass mortality events, notification isn’t optional: the State Veterinarian with the Tennessee Department of Agriculture should be notified when catastrophic losses are greater than 10,000 pounds. This threshold also applies to deer and other species processed through licensed facilities, which is worth knowing if you handle carcasses connected to hunting laws in Tennessee.

Pro Tip: If you’re facing a mortality event over 10,000 pounds, call the State Veterinarian’s office before choosing a disposal method — landfilling, composting, and rendering may be your only viable options at that scale.

Which Agency Regulates Manure and Carcass Disposal in Tennessee

Two state agencies split this responsibility, and knowing which one to call saves time. The Tennessee Department of Agriculture (TDA) administers the state’s animal disposal policy and houses the State Veterinarian’s office, which handles catastrophic mortality reporting and general disposal guidance for farm animals.

TDA also controls a seasonal piece of the puzzle: burn permits are issued by the Tennessee Department of Agriculture’s Division of Forestry from October 15 through May 15. Outside that window, or without a permit inside it, open burning of any kind — including carcass burning — can run afoul of state fire regulations.

TDEC handles the environmental side: solid waste classification for carcasses and landfills, air pollution permitting exemptions for incinerators and burning, and water quality regulation for AFOs and CAFOs. Medical waste disposal in Tennessee is regulated under TDEC, specifically through the Division of Solid Waste Management — the same division that oversees landfill acceptance rules for dead animals. A third division, TDEC’s Water Resources program, issues the discharge permits that CAFOs need under the federal Clean Water Act framework.

Local government adds a third layer. Cities and counties can pass their own ordinances covering public dumping and nuisance conditions, and those rules apply on top of state requirements. If wildlife activity around a farm — drawn by improperly stored waste or carcasses — becomes a separate concern, Tennessee’s nuisance wildlife laws in Tennessee cover what you can legally do about it.

Water Setbacks, Groundwater Protections, and Health Standards in Tennessee

Water protection sits at the center of nearly every disposal rule in this space, because both manure and carcasses can contaminate wells, streams, and groundwater if handled carelessly. The University of Tennessee’s own guidance to producers is direct: burial and other disposal choices must respect setbacks from sources of water — wells and surface water — and the animal must be buried more than two feet away from bedrock or water tables.

For AFOs and CAFOs, the setback requirements are more specific and codified in state rule. As covered above, manure and process wastewater can’t be applied within 100 feet of a potable well, and a 60-foot riparian buffer is required near the state’s highest-quality waters. These distances aren’t recommendations — they’re baked into the technical standards that every land-application plan on a regulated operation has to meet.

Local health departments can layer on additional restrictions beyond what the state requires, particularly around burial sites near residential wells or in areas with shallow water tables. Before choosing a burial location, checking with your county health department is a reasonable extra step, since Tennessee’s baseline rules set a floor, not necessarily the strictest possible standard for every location.

Key Insight: State setback distances are minimums. Karst geology, shallow bedrock, or a nearby private well can all justify moving a burial or composting site further from water sources than the law technically requires.

CAFO and Nutrient Management Plan Requirements in Tennessee

Operations large enough to qualify as a Concentrated Animal Feeding Operation (CAFO) face a heavier regulatory load than smaller farms. Tennessee’s rules define tiers — AFO, CAFO, and Large CAFO — based on the number and type of animals confined, with “Large CAFO” or “Class I CAFO” meaning an AFO that confines greater than or equal to the number of animals specified in the state’s classification table.

Every CAFO needs a nutrient management plan, and in practice this is usually a Comprehensive Nutrient Management Plan (CNMP). TDEC does not aid in the development of the CNMP for the CAFO — it’s developed by a certified nutrient management planner, and most operations use NRCS’s services to develop it. Cost-share money is available through NRCS for CNMP development, and a CNMP is also required to secure an FSA loan for building the facility.

Some gaps in Tennessee’s CAFO framework are worth knowing about if you’re planning a new facility or live near one. Currently, Tennessee does not have any laws or regulations that govern setbacks for agricultural building sites — the 100-foot and 60-foot distances discussed earlier apply to land application, not to where a barn or lagoon itself can be sited. Air quality oversight is similarly limited: Tennessee does little to regulate air pollution or odors from AFOs, and CAFOs are exempt from being required to have an air quality permit.

When TDEC does issue a discharge permit to a CAFO, the process isn’t entirely private. Depending on the type of permit, TDEC may be required to issue public notice, generally published in a local newspaper in the community where the proposed permit will take effect. That transparency requirement gives neighboring landowners a formal chance to weigh in before a permit is finalized. For farm families weighing how these permit obligations intersect with broader agricultural protections, our guide to right-to-farm laws in Tennessee covers where those protections do and don’t extend.

Penalties for Illegal Dumping, Missed Carcass Deadlines, and Water Violations in Tennessee

Improper disposal carries real legal exposure, and it starts at the local level. Under Johnson City’s municipal code, for example, it is unlawful for any person to place or throw any dead animal onto the streets or other public places, and the owner is responsible for disposing of or burying the animal in an appropriate, licensed disposal facility as soon as possible. Similar dumping prohibitions exist in municipal codes across the state, meaning a missed 48-hour disposal window can turn into a public-nuisance violation even before any state agency gets involved.

On the water quality side, enforcement typically runs through TDEC’s Division of Water Resources using consent orders and corrective-action requirements rather than a flat published fine schedule. A real example from a Tennessee dairy operation shows how this works in practice: after a documented discharge, the operator was required to provide a written discharge report to TDEC within 5 working days and to bring waste application practices back into line with the facility’s approved nutrient management plan. Consent orders like this can include corrective timelines, monitoring requirements, and in more serious or repeat cases, civil penalties.

Common Mistake: Assuming the “no permit needed” exemptions for burial, composting, or small manure stockpiles mean there’s no way to violate the law. Those exemptions only apply if you stay within the size, setback, and technical standards attached to them — exceed any one of those limits and you’re back under full permitting requirements.

Neglecting carcass disposal can also intersect with animal welfare enforcement in cases involving live animals in distress, a separate but related area covered under Tennessee’s animal cruelty laws in Tennessee. While waste disposal violations and cruelty charges are legally distinct, inspectors responding to one complaint sometimes uncover the other.

How to Confirm Current Tennessee Animal-Waste Rules With the Agencies

Because these rules span multiple agencies and get updated periodically, verifying current requirements before you act is worth the phone call. Here’s a practical order of operations:

1. Start with TDA for disposal method questions. The Tennessee Department of Agriculture’s Animal Disposal Policy page covers burial, composting, landfilling, rendering, and incineration standards for dead farm animals.
2. Call the State Veterinarian for mass mortality events. Any loss over 10,000 pounds requires notification before you choose a disposal method.
3. Contact TDEC’s Division of Solid Waste Management for landfill and carcass classification questions. This division determines which landfills can legally accept dead animals.
4. Reach TDEC’s Water Resources program for AFO/CAFO permitting. This is the office that reviews nutrient management plans and issues discharge permits.
5. Check with the TDA Division of Forestry before any open burning. Burn permits run seasonally, and local fire ordinances can override state timing.
6. Call your county health department for local burial or setback restrictions. State rules set a floor; counties can require more.

University of Tennessee Extension is also a reliable secondary resource. Its agricultural waste management program publishes updated guidance for producers, including maps of which Class I landfills accept dead livestock across the state — useful since not every facility that’s technically allowed to take carcasses actually chooses to.

Finally, if your operation is expanding toward CAFO thresholds, an outside advocacy resource like the Socially Responsible Agriculture Project’s Tennessee CAFO guide lays out permit timelines and public notice procedures in more detail than most state summaries. Cross-checking a plain-language guide like that against the official rule text at Tenn. Comp. R. & Regs. 0400-40-05-.14 gives you both the practical and legal picture before you commit to a facility design or expansion.
