Animal Waste Disposal Laws in Indiana: What Livestock Owners Need to Know
October 3, 2026
If you raise livestock in Indiana, you’re bound by rules that most homeowners never think about: a strict clock on carcass disposal, detailed manure storage standards, and water-quality setbacks enforced by state inspectors. Miss a deadline or skip a permit, and you could face a formal Notice of Violation from the state’s environmental agency.
This guide breaks down what Indiana actually requires for livestock waste and dead-animal disposal, who enforces those rules, and how to stay compliant whether you run a small farm or a large confined feeding operation.
What Indiana Requires for Livestock Waste and Dead-Animal Disposal
Indiana splits animal waste regulation into two distinct tracks. Manure handling and disposal issues are regulated by the Indiana Department of Environmental Management, while dead-animal disposal falls under a separate statute enforced by the Indiana State Board of Animal Health.
For carcasses, the timeline is unforgiving. Indiana State Board of Animal Health guidance states that state law requires an animal owner to dispose properly of a livestock carcass within 24 hours of learning of an animal’s death. That obligation traces back to Indiana Code, which requires “a person who owns or cares for an animal that has died from any cause to dispose of the animal’s body not later than twenty-four (24) hours after knowledge of death so as not to produce a nuisance.”
These carcass rules apply specifically to livestock and poultry. Pets and wildlife do not fall under Indiana’s dead animal disposal law, though local governments (city/county) may have requirements for disposal of these species. If you’re dealing with roadside wildlife rather than farm animals, Indiana’s roadkill laws cover a different set of obligations entirely.
Pro Tip: Keep a written log of when you discovered each animal’s death and which disposal method you used. If BOAH or IDEM ever questions your timeline, documentation is your best defense.
Manure Storage, Stockpiling, and Land-Application Rules in Indiana
Manure management in Indiana isn’t a matter of personal preference once you cross certain size thresholds. The rules governing how you stage, stockpile, and apply manure to land are found in 327 IAC 16, and they’re detailed enough to trip up producers who assume “we’ve always done it this way” is a legal defense.
Staging manure at an application site comes with a hard clock. Under state regulation, manure that is staged at the manure application site for more than seventy-two (72) hours must be covered or otherwise protected, and applied to the site within ninety (90) days. Land application itself carries its own conditions: manure must be staged or applied so it does not enter or threaten to enter waters of the state, must prevent runoff, ponding for more than twenty-four (24) hours and spills, and must minimize nutrient leaching beyond the root zone.
If you’re setting up permanent manure storage structures, zoning and siting decisions matter just as much as the storage design itself. Many counties layer their own zoning requirements on top of state rules, particularly for structures classified as a business use. Producers raising smaller livestock, such as those covered under goat ownership laws, may fall below CFO thresholds but should still confirm local ordinance requirements before building a manure storage pad.
| Manure Practice | Indiana Requirement |
|---|---|
| Staging without cover | Must be covered/protected after 72 hours |
| Time to land application after staging | Within 90 days |
| Ponding during application | Cannot exceed 24 hours |
| Contact with waters of the state | Prohibited, including threatened contact |
How You Must Dispose of Dead Livestock Carcasses in Indiana
The Indiana State Board of Animal Health recognizes seven approved disposal methods, and BOAH has approved seven carcass disposal methods for animal remains: burial, above-ground burial, incineration, composting, rendering, exotic animal feeding, and anaerobic and chemical digestion. Each option comes with its own technical specifications you need to follow to stay compliant.
Traditional burial has strict depth requirements. Guidance for swine producers specifies that by law, the entire carcass must be buried at least 4 feet below the natural surface of the ground, and all body parts must lie under 4 feet of earth, not including other types of covering material (such as mulch). Above-ground burial is a documented alternative when digging that deep isn’t practical: when burying carcasses above ground, soil excavation of the burial trench must be to a depth in the range of 20 inches to 24 inches with at least 12 inches of carbonaceous material covering the entire bottom of the trench.
Landfill disposal is also legal, since landfill disposal qualifies as burial under BOAH rules, though each landfill operator decides what material it will accept. Open burning is not an option under any circumstances — a barrel or open burn pile is illegal under the Indiana Department of Environmental Management (IDEM) rules. If you’re considering an on-farm incinerator instead, you’ll need to check with IDEM’s Air Division first, since producers choosing to install an on-farm incinerator should contact IDEM’s Air Division to determine if a permit is required.
Composting is popular among producers because it produces usable material. By following a proven “recipe,” an established on-farm composter can produce nutrient-rich organic matter suitable for field application in a few months. But confined operations need to plan ahead: under IDEM rules, confined feeding livestock facilities composting carcasses must include the compost facility in their permit application. Run-on water and leachate also need controls, since run-on and leachate runoff must be prevented or controlled.
One important exception to know: rendering isn’t available for every animal. NOTE: Animals euthanized with pentobarbital cannot be rendered and should be identified. If you’re moving livestock — alive or deceased — across county lines for any of these disposal methods, review Indiana’s livestock transportation laws first, since carcass movement carries its own documentation requirements separate from live-animal hauling.
Important Note: These carcass rules apply to livestock and poultry, not to small animal species. Fish, reptiles, dogs, cats, and small game are exempt, as are dead livestock being transported by the owner directly to a diagnostic facility.
Which Agency Regulates Manure and Carcass Disposal in Indiana
Two state agencies split enforcement, and knowing which one to call saves you time when you have a compliance question. The Indiana State Board of Animal Health (BOAH) oversees dead-animal disposal methods as a matter of animal and public health, while the Indiana Department of Environmental Management (IDEM) regulates manure, wastewater, and anything tied to water or air quality.
BOAH’s role centers on carcass handling: licensing rendering plants, approving disposal methods, and investigating reports of improperly disposed livestock. Anyone operating a business that accepts carcasses from outside sources needs BOAH sign-off, since Indiana Code Title 15, Article 17, Chapter 11 requires a disposal plant license and a transport vehicle license certificate for trucks used to haul carcasses commercially.
IDEM’s jurisdiction covers the larger environmental picture. It issues Confined Feeding Operation approvals, sets manure storage design standards, and investigates water pollution complaints. If your operation crosses into confined feeding territory, the IDEM Confined Feeding Program is the office you’ll deal with directly. This division of labor also matters for anyone dealing with wildlife-adjacent issues, since state wildlife rules under Indiana’s hunting regulations fall to yet another agency, the Department of Natural Resources.
Water Setbacks, Groundwater Protections, and Health Standards in Indiana
Water protection sits at the center of Indiana’s manure regulations, and the setback distances are specific enough that you can’t eyeball them. According to the Guidance Manual for Indiana’s Confined Feeding Program, the required setback to surface waters of the state is 300 feet for liquid manure storage structures and 100 feet for solid manure storage structures. Wetlands get extra scrutiny too, since any wetland area within 500 feet of a proposed structure should be identified on the facility farmstead plan.
These setbacks aren’t just paperwork formalities — IDEM actively enforces them. A 2019 inspection of a confined feeding operation in Martin County led to violations and a formal agreement, illustrating that IDEM investigators do site visits and compare actual conditions against approved plans. Producers raising marked or tagged livestock, such as those following swine ear-notching requirements, should apply the same level of documentation discipline to their manure structures and setback compliance records.
Non-disease mortality events get their own water-quality consideration too. IDEM has clarified that municipal solid waste land disposal facilities (landfills), permitted under 329 Indiana Administrative Code (IAC) 10, are properly sited and have the necessary environmental controls to manage animal carcasses in a manner that is protective of human and animal health and the environment. That’s part of why landfill disposal remains an approved carcass option even during larger mortality events like natural disasters or processing capacity shortfalls.
CAFO and Nutrient Management Plan Requirements in Indiana
Whether your farm needs a Confined Feeding Operation (CFO) or Concentrated Animal Feeding Operation (CAFO) approval comes down to animal numbers and confinement time. Indiana defines the threshold clearly: if there is enough of one type of a regulated animal on a farm in Indiana, and the animals are confined for at least 45 days a year, it is considered to be a confined feeding operation (CFO) and is regulated under certain Indiana laws and rules. The distinction between CFO and CAFO comes down to scale, since the terms CFO and CAFO relate to the size of the CFO, with the largest operations facing federal Clean Water Act permitting on top of state requirements.
Once approved, a CFO doesn’t get to operate indefinitely without renewal. A CFO approval is good for five years from the date it was issued, and an owner or operator must submit a renewal application to IDEM at least 30 days before the approval expires. IDEM sends reminders, but the owner or operator is responsible for meeting the renewal application deadline even if IDEM reminder never arrives.
Local zoning still plays a role even though the state controls operational standards. A legal analysis prepared for Indiana’s agricultural policy office notes that it is helpful to remember that local governments play a critical role in determining where a livestock barn may locate while the State has the authority to regulate how livestock farms must operate to protect public health and safety. That analysis adds that implementing setback requirements and minimum lot sizes are traditional land use tools utilized by counties to regulate the location of livestock farms. Producers who also keep smaller flocks or herds under separate rules, such as those covered by Indiana’s duck-related wildlife regulations, should remember that CFO rules apply only to confined domestic livestock and poultry, not to hunted or wild waterfowl.
Key Insight: A five-year CFO approval sounds distant until it isn’t. Mark your renewal deadline the day your approval letter arrives, since IDEM only requires a 30-day notice window before expiration.
Penalties for Illegal Dumping, Missed Carcass Deadlines, and Water Violations in Indiana
IDEM doesn’t hesitate to document violations when inspections turn up problems. Enforcement typically starts with a Notice of Violation, and one Jasper County case shows how multiple infractions can stack: the operation was cited for manure to be staged or applied to land in Indiana without preventing runoff, for operating an unregistered confined feeding operation, and for staging manure unprotected past the 72-hour limit, all in a single notice.
When violations are confirmed, civil penalties follow. In one resolved case involving a Martin County confined feeding operation, the operator agreed to pay a civil penalty of Five Thousand Dollars ($5,000) after an IDEM inspection found violations at the site. Indiana’s broader pollution statute backs these actions, since a person may not discharge, emit, cause, allow, or threaten to discharge, emit, cause, or allow any contaminant or waste into the environment or any publicly owned treatment works in any form that causes or would cause pollution.
Missing the 24-hour carcass disposal deadline creates a separate compliance risk tied to nuisance law rather than water pollution statutes, and repeated failures can draw the attention of local health authorities in addition to BOAH. Anyone concerned about neighbor complaints tied to odor or improper disposal should also review Indiana’s animal welfare statutes, since neglect complaints sometimes overlap with waste disposal violations when carcasses are left unaddressed.
How to Confirm Current Indiana Animal-Waste Rules With the Agencies
Regulations get amended, and guidance documents get updated more often than most producers realize — several BOAH fact sheets referenced in this article have been revised more than once in recent years. Before you finalize a disposal plan or design a manure structure, verify the current rule text directly with the agency responsible for that area.
- For carcass disposal questions, contact the Indiana State Board of Animal Health directly or review their published FAQ page.
- For manure, CFO, and water-quality questions, reach out to your regional IDEM Confined Feeding Program contact listed on the agency’s CFO program page.
- For zoning and setback questions, check with your county plan commission, since local ordinances can add siting requirements the state doesn’t cover.
- For questions involving pets, wildlife, or non-livestock species, contact local law enforcement or your county health department, since wildlife carcass rules and pet disposal fall outside BOAH’s livestock-focused statute.
Keep a copy of any written guidance you receive from BOAH or IDEM staff. If your operation is later inspected, having that correspondence on file demonstrates a good-faith effort to comply with current rules rather than outdated guidance.
Common Mistake: Relying on a neighbor’s or previous owner’s disposal practices instead of confirming current requirements directly with BOAH or IDEM. Rules on setbacks, staging time limits, and permit thresholds have changed over the years, and what was compliant a decade ago may not be compliant now.
Indiana’s animal waste framework asks a lot of livestock owners, from the 24-hour carcass clock to five-year CFO renewal cycles and 300-foot water setbacks. Treat compliance as an ongoing task rather than a one-time checklist, and confirm details with BOAH or IDEM whenever you’re planning a new structure, adding animals, or changing your disposal method.
