Animal Waste Disposal Laws in South Dakota: Carcass Removal, Manure Storage, and CAFO Permits
October 5, 2026
South Dakota gives livestock owners a strict 36-hour window to dispose of an animal that dies from non-communicable causes, and the state backs that deadline with specific burial depths, incineration setbacks, and rendering rules. If you raise cattle, hogs, poultry, or any other livestock in the state, animal waste disposal laws in South Dakota touch nearly every part of your operation, from where you stockpile manure to how far a carcass burial site must sit from a neighbor’s property line.
This guide breaks down what state law and agency rules actually require, who enforces them, and what happens if you get it wrong. Whether you run a small acreage with a handful of goats or manage a permitted feedlot, understanding these rules protects your operation from fines and protects your water supply from contamination.
Pro Tip: Save the phone numbers for both the South Dakota Animal Industry Board and your regional DANR office before you need them — carcass and manure violations both carry short response windows.
What South Dakota Requires for Livestock Waste and Dead-Animal Disposal
South Dakota splits animal waste regulation into two tracks: dead-animal disposal, overseen by the South Dakota Animal Industry Board, and manure management, overseen primarily by the Department of Agriculture and Natural Resources (DANR). South Dakota law requires that animals who have died from non-communicable causes shall be properly disposed of within 36 hours by either burning, being buried to a depth of four feet, incorporated into a composting system or disposed of by a licensed rendering plant. This rule sits in the Administrative Rules of South Dakota, and carcasses of animals which have died from noncommunicable causes shall be burned, buried to a depth of four feet, or disposed of by a licensed rendering plant within 36 hours, effective under authority granted by SDCL 40-3-14.
The law exists for a practical reason. Proper carcass disposal is crucial in preventing the spread of disease and protecting the environment. Manure rules follow a separate but related logic — protecting surface and groundwater from nutrient runoff while giving producers workable storage and application options.
If you haul livestock to sale or between properties as part of your operation, the disposal timeline can overlap with transport logistics, so it helps to understand South Dakota’s livestock transport rules alongside disposal requirements. Producers who brand cattle for ownership identification should also note that South Dakota’s branding laws can affect how a downed animal is documented before disposal.
Manure Storage, Stockpiling, and Land-Application Rules in South Dakota
Manure storage and land application in South Dakota fall under the state’s general water pollution control permit for concentrated animal feeding operations, administered by DANR. CAFO regulation in South Dakota is guided by a comprehensive general water pollution control permit for concentrated animal feeding operations, providing general permit guidance to producers for planning requirements, site planning, collection and storage of manure, design criteria, nutrient management plans, soil and manure testing, and manure application restrictions.
Even outside a formal CAFO permit, land application timing matters. Applying dry or solid manure on frozen and snow-covered ground should be avoided, and if manure is surface broadcast on frozen or snow-covered ground, the land must have slopes of less than 4% and a 100-foot buffer zone must be maintained to wetlands and waterways. This buffer standard emerged partly from state-funded research: because there was no significant difference found between applying manure to the upper half of the watershed compared to the lower half, producers gained greater flexibility for winter manure application while water quality remained protected.
Producers using phosphorus-sensitive fields also carry a paperwork obligation. Manure application rates must be calculated using form SD-CPA-8 or SD-CPA-63, and these calculations must be completed before land application of manure occurs, with a copy kept on file to comply with permit requirements.
| Manure Application Scenario | Key Requirement |
|---|---|
| Normal-season land application | Nutrient management plan calculations completed and documented before spreading |
| Winter/frozen-ground application | Slope under 4% and 100-foot buffer to wetlands and waterways |
| Phosphorus-elevated fields | Phosphorus-based rate calculation using SD-CPA-8 or SD-CPA-63 |
| Manure purchased from an out-of-state facility | Confirm whether the source qualifies as a CAFO, since general permit restrictions apply only in that case |
Ranches running livestock across large pastures should also understand how grazing patterns interact with manure distribution under South Dakota’s open range laws, since range-fed animals are treated differently than confined operations. Smaller producers keeping a backyard flock should review South Dakota’s backyard chicken laws, which touch on coop waste handling at a much smaller scale than a permitted feedlot.
How You Must Dispose of Dead Livestock Carcasses in South Dakota
South Dakota recognizes four legal disposal methods for a carcass that died of non-communicable causes, and each comes with its own siting rules. Burial is often the simplest option: burial is an inexpensive and biosecure way to handle dead stock, but site selection matters. Producers should avoid extremely porous soils or areas with high amounts of sand or gravel, stay outside of a wetland, and keep burial sites at least 200 feet from a road right-of-way or property boundary unless they have permission from the adjacent property owner.
Pro Tip: Call before digging using the SD One Call System at 1-800-781-7474 or dial 811 to avoid hitting buried utility lines during carcass burial.
Incineration works as a cold-weather alternative when burial or composting isn’t practical. It can be difficult to either bury or compost dead animals in cold weather, so the SD Animal Industry Board recommends specific guidelines when incineration is used instead. Those guidelines are strict about location and monitoring: notify local fire departments prior to initiating, keep the site at least 1,000 feet from an occupied dwelling, propane tank, fuel tank, or other flammable-substance containers, only burn during favorable weather conditions, and monitor the smoke plume so it does not impact neighbors, highways, or airport traffic. Producers should never use inappropriate accelerants for this process.
Rendering is the fourth path, and it comes with its own transport requirements. Vehicles that haul carcasses for rendering services need to be inspected and permitted by the Animal Industry Board, and carcasses and animal parts must be transported in leak-proof vehicles or containers that are covered. The Animal Industry Board maintains a list of licensed rendering companies that operate in the state.
If a carcass results from vehicle collision rather than natural death, disposal falls under a different framework — see how South Dakota’s roadkill laws treat that situation. Hunters face a separate set of carcass rules tied to disease management: hunters are recommended to leave as much of the unusable carcass as possible at the location of the harvest in a discrete location on both public and private lands, a practice detailed further in South Dakota’s hunting regulations. Out-of-state game carcasses face stricter handling: deer or elk carcasses from another state brought back into South Dakota must be disposed of with a waste management provider or landfill that accepts carcass parts.
Which Agency Regulates Manure and Carcass Disposal in South Dakota
Two state agencies split oversight, with counties handling a third layer. Carcass disposal is regulated by South Dakota law with oversight provided by the South Dakota Animal Industry Board. Manure and water-quality issues run through DANR instead: the issuing agency for the state’s environmental policy framework is the South Dakota Department of Agriculture and Natural Resources.
| Agency | Primary Jurisdiction |
|---|---|
| South Dakota Animal Industry Board | Carcass disposal methods, rendering vehicle permits, disease prevention |
| DANR Feedlot Permit Program | CAFO permits, manure storage, nutrient management plans, land application |
| County Boards of Adjustment / Zoning | Local setback ordinances, land-use complaints, CAFO siting disputes |
Local government carries real weight here too. The legislature has given the authority to establish setbacks to structures and other land uses to counties and municipal planning and zoning bodies, and local government is responsible for administering their ordinances — the state permit does not supersede or remove liability for compliance with local government ordinances. That division of labor can create real friction on the ground. When a county Board of Adjustment received waste-management complaints against a livestock operation, complaints about pollution of waters of the state or wetlands would have been forwarded to DANR for their interpretation, and the board did forward a report requesting state assistance in reviewing whether waste was being managed in accordance with state rules, specifically regarding water quality.
Producers running mixed operations, including goats alongside cattle, should check South Dakota’s goat ownership laws to see how smaller livestock counts interact with the same disposal and manure rules that apply to cattle and hog operations.
Water Setbacks, Groundwater Protections, and Health Standards in South Dakota
Water protection threads through nearly every disposal rule in South Dakota, whether it applies to a single carcass or a full CAFO. On the carcass side, burial siting doubles as a groundwater safeguard: avoiding extremely porous soils, areas with high amounts of sand or gravel, and any location inside a wetland keeps decomposition byproducts from reaching drinking water sources.
On the manure side, the general CAFO permit sets an absolute standard for the production area. The producer shall have no discharge of manure, litter, process wastewater or other organic by-products from the production area to waters of the state. That zero-discharge requirement is why winter application buffers matter so much — the 100-foot buffer zone to wetlands and waterways mentioned earlier exists specifically to keep runoff-prone winter spreading from violating that standard.
Nutrient runoff was significant enough to justify dedicated state research. Nonpoint source discharges of pollutants can be significant if manure is not managed properly, especially where high concentrations of livestock are present, since manure land application sits at the center of ongoing water resource debate. Wildlife-adjacent waste can raise similar concerns, which is part of why South Dakota’s nuisance wildlife laws intersect with proper carcass and waste handling on working land.
CAFO and Nutrient Management Plan Requirements in South Dakota
Any operation that meets South Dakota’s CAFO threshold needs more than a manure pile in the right spot — it needs an engineered plan on file with the state. The permit application must include completed certification of applicant and notice of intent forms, plans and specifications signed and stamped by a South Dakota licensed engineer, a signed operation and maintenance guideline, a training certification, and a nutrient management plan that meets all the requirements of the permit. Only after DANR signs off does construction begin: following DENR’s review and approval of the permit application, construction of the manure management system can begin.
Training isn’t a one-time formality either. Producers applying for coverage under the general permit must submit verification that the producer has taken a training program on the operation and maintenance of a manure management system and natural resource management, and SDSU Cooperative Extension currently offers a one-day training course about four times a year to meet this requirement.
Nutrient management plans aren’t static documents once approved. The operator shall review the NMP annually and update it when significant operational changes occur or when monitoring dictates the need for change, and changes or updates to the NMP must be approved by DANR in writing before the changes are implemented. A working cattle operation in Edmunds County described the day-to-day reality of this: as part of manure management, producers have to take soil tests and make sure not to put too much on, they are required to have a manure management plan regulated by the state and checked every year, and DANR also evaluates water usage to make sure producers are not taking somebody else’s water.
Not every livestock setup needs this level of paperwork, though. The CAFO definition excludes pastured livestock and most wintering areas from the general permit process, though that does not mean these practices do not cause pollution at times and would benefit from a voluntary program to prevent water pollution. Beekeepers and other small-scale animal keepers who fall well outside CAFO thresholds should still review the general framework in South Dakota’s beekeeping laws to understand where their operations sit relative to livestock waste rules.
Penalties for Illegal Dumping, Missed Carcass Deadlines, and Water Violations in South Dakota
South Dakota tiers illegal dumping penalties by weight and intent, and the thresholds matter because they determine whether a violation is a misdemeanor or a felony. Illegal disposal of solid waste in a quantity less than ten pounds constitutes littering, disposing of ten pounds or more but less than two thousand pounds — or unintentionally disposing of more than two thousand pounds — is illegal dumping in the second degree, and knowingly and intentionally disposing of more than two thousand pounds is illegal dumping in the first degree. Illegal dumping in the first degree is a Class 6 felony, while illegal dumping in the second degree is a Class 1 misdemeanor.
Important Note: Penalty tiers for solid waste violations can be substantial for permitted facilities. According to a 2025 industry compliance review, as of January 2025, penalties for South Dakota solid waste violations can reach $93,058 per violation per day. Confirm current figures directly with DANR, since civil penalty caps are periodically adjusted.
Enforcement isn’t limited to fines. DANR and the EPA can issue administrative orders, fines, or pursue criminal charges for violations, and biennial reporting failures carry their own consequences: facilities must submit timely biennial reports, and late or missing reports can result in significant penalties.
Missing the 36-hour carcass deadline doesn’t automatically trigger a felony charge the way large-volume dumping might, but it does put an operation out of compliance with SDAIB rules and can prompt an inspection. Complaints about water-related violations follow a distinct path: as one DANR spokesperson explained regarding a livestock waste dispute, the department will investigate as needed to determine compliance with their general permit and applicable state laws and rules. This general regulatory framework exists alongside the state’s broader environmental statutes, including provisions covering unauthorized dumping and disposal in water.

How to Confirm Current South Dakota Animal-Waste Rules With the Agencies
Rules change, permit versions get updated, and local ordinances vary by county, so verifying current requirements before you act saves you from costly mistakes. Here’s a practical order of operations:
- Call the South Dakota Animal Industry Board for carcass disposal method questions, rendering hauler permits, or disease-related disposal concerns.
- Contact DANR’s Feedlot Permit Program for CAFO permit status, nutrient management plan requirements, and manure application questions.
- Check with your county planning and zoning office for local setback ordinances, since these can be stricter than the state’s baseline permit.
- Reach out to SDSU Extension for manure management training schedules and technical guidance on nutrient testing.
- Review the current general permit text directly rather than relying on older summaries, since DANR periodically revises permit language.
The South Dakota Animal Industry Board’s carcass disposal page and the DANR CAFO FAQ are both maintained directly by the regulating agencies, which makes them more reliable than third-party summaries when a rule may have shifted. For hands-on calculation tools, DANR’s nutrient management resources page hosts the current application-rate worksheets producers are required to keep on file.
Producers managing livestock ownership records alongside waste compliance may also find it useful to review how South Dakota regulates livestock transport, since hauling animals or hauling carcasses for rendering both intersect with state inspection requirements. When in doubt, a short call to the agency in question is faster — and far less costly — than guessing.
