Animal Waste Disposal Laws in North Dakota: Manure, Carcasses, and CAFO Rules Farmers Must Follow
October 28, 2026
When Ward County investigators pulled 472 dead cattle out of an open pit on a feedlot northeast of Surrey, it wasn’t just a biosecurity problem — it was a violation of animal waste disposal laws in North Dakota that carry real legal consequences. The case, which also drew in the state’s environmental regulators, is a reminder that dead-animal and manure rules in this state aren’t suggestions.
Whether you run a cow-calf operation, keep a small flock of laying hens, or manage a permitted CAFO, North Dakota’s disposal framework touches nearly every livestock owner in the state. This guide walks through what the law requires for manure storage, carcass disposal deadlines, water protection setbacks, and the penalties that follow when producers cut corners.
What North Dakota Requires for Livestock Waste and Dead-Animal Disposal
North Dakota treats manure management and dead-animal disposal as two related but separate compliance obligations. For routine mortalities, NDSU Extension guidance states that the producer is responsible for disposing of these mortalities within 48 hours in an environmentally acceptable manner. That standard applies to everyday losses from accidents, disease, or weather events.
Leaving a carcass where it fell is never an acceptable shortcut. Carcass abandonment is not considered an acceptable disposal practice under state guidance, and the same expectation extends to manure — piling it near a ditch or letting runoff reach a waterway invites the same enforcement scrutiny as an unburied animal.
If you keep smaller livestock, the same core obligations apply on a smaller scale. Owners covered by goat ownership laws in North Dakota and backyard flock keepers following backyard chicken laws in North Dakota still need a disposal plan for mortalities, even if the volume is far smaller than a commercial feedlot’s.
Pro Tip: Decide on a mortality management method before an animal dies. Scrambling to find a landfill, compost site, or burial spot after the fact is how producers end up missing deadlines.
Manure Storage, Stockpiling, and Land-Application Rules in North Dakota
Any operation large enough to need a manure storage structure — a pond, pit, or stockpile area — falls under the state’s permitting system. Owners and operators of these facilities must obtain a state permit from the NDDEQ AFO/CAFO Permit Program, and that permit dictates how manure is stored, monitored, and eventually applied to fields.
Storage structures aren’t a build-it-and-forget-it system. Permit conditions typically require weekly inspections of the manure storage structures noting the level of liquid in the structure as indicated by the depth marker. Operators are also expected to track precipitation, since the operator of a livestock facility should maintain a rain gauge at the production area and record measurable rainfall events.
Land application isn’t unlimited, either. Before manure can be spread as fertilizer, an operation generally needs to show it has enough acreage to absorb the nutrients responsibly. In the Riverview Herberg Dairy permit near Hillsboro, for example, NDDEQ confirmed that Riverview identified sufficient cropland acreage to apply manure as fertilizer in accordance with North Dakota nutrient management standards. Fields inside flood-prone zones can be excluded even after that acreage requirement is met — in the same permit, fields within the 100-year floodplain were excluded from approval, though the operation still meets the minimum acreage required for its nutrient management plan.
Storage structures themselves also need to meet design standards, and fencing plays a role in keeping livestock away from active storage areas. If you’re setting up pens or containment near a manure system, cross-checking livestock fence laws in North Dakota alongside your manure plan helps you avoid redesigning both later.
| Manure Management Requirement | What It Involves |
|---|---|
| State Permit | Required from the NDDEQ AFO/CAFO Permit Program before construction of storage structures |
| Weekly Inspections | Depth markers checked to track liquid levels in storage ponds or pits |
| Rain Gauge Records | Measurable rainfall events logged at the production area |
| Cropland Acreage | Sufficient land identified to absorb manure nutrients through land application |
| Floodplain Exclusions | Fields in 100-year floodplains may be removed from the approved application area |
How You Must Dispose of Dead Livestock Carcasses in North Dakota
North Dakota recognizes four approved disposal methods for dead livestock: rendering, incineration, burial, and composting. As one NDSU livestock specialist put it, “Burying is something done very regularly as long as producers are careful about the water table.” Rendering has become the least practical option in most of the state — rendering no longer is a common disposal method in North Dakota because of the lack of facilities and the cost, which pushes many producers toward burial or composting by default.
Important Note: You’ll see two different timeframes cited for carcass disposal. NDSU Extension’s general guidance allows 48 hours in an environmentally acceptable manner for routine mortalities, while state reporting on enforcement cases and disease-related carcasses points to a stricter 36-hour window for rendering, composting, burning, or burial. When disease is confirmed or suspected, the shorter deadline applies.
Burial depth is not left to guesswork. If a carcass is buried, it has to be buried at least 4 feet below the surface of the ground and covered with dirt to the ground level. Location matters just as much as depth — carcasses can’t be disposed of along highways or along streams, lakes or rivers. If the death involved euthanasia drugs, veterinarians recommend going deeper still, since shallow graves can poison scavengers that dig into the site. Composting has become a favorite among ND producers because it works year-round and requires no fuel. But it’s not a universal fix: while composting is a preferred disposal method in most situations, it is not appropriate when the death was due to anthrax poisoning. Anthrax and other contagious diseases trigger their own set of rules under the North Dakota Century Code. If the animal died of anthrax, as determined by a licensed veterinarian, the carcass must be completely burned at the place where it died if possible, and moving it is tightly restricted — if the carcass must be moved, it may not be dragged over the ground but must be moved only on a suitable conveyor and all body openings in the carcass must be plugged with cotton saturated with a strong antiseptic solution, according to North Dakota Century Code § 36-14-19.
Hog producers face a specific rule of their own. If the carcass is of a hog which died from hog cholera or swine erysipelas, the same, with hide intact, must be burned within thirty-six hours or given to a licensed rendering plant within such time. If you suspect anthrax rather than a routine death, contact the right agency immediately — when anthrax is suspected, producers should contact the Board of Animal Health or local veterinarians, who can advise on next steps for disposal.
Landfills can be part of the solution, though they’re not obligated to help. There are 13 landfills in the state that are permitted to take livestock carcasses, though they do not have to. That’s worth confirming before you count on a landfill as your backup plan.
Scavengers add another wrinkle to on-farm disposal. Coyotes and raccoons are known to dig into compost piles and poorly covered burial sites, which is one more reason a well-designed system matters. If persistent wildlife is digging up carcass or manure sites on your land, the rules under nuisance wildlife laws in North Dakota and coyote hunting laws in North Dakota outline what you can legally do about it. If you need help moving or hauling a large carcass off-site to a rendering plant, the transport requirements under transporting livestock laws in North Dakota apply as well.
Dead-animal disposal rules aren’t limited to farm livestock, either. Hunters dealing with wildlife carcasses face a parallel set of requirements — see how those compare under roadkill laws in North Dakota and chronic wasting disease laws in North Dakota, both of which set landfill and disposal expectations for carcass waste outside the livestock context.
| Disposal Method | Key Requirement | Best Suited For |
|---|---|---|
| Rendering | Must reach a licensed plant within required timeframe; few facilities remain in-state | Producers near a rendering plant |
| Incineration | Requires proper container/filters and NDDEQ air quality permitting | Poultry and small-livestock operations |
| Burial | At least 4 feet deep (6 feet for anthrax); away from water and floodplains | Most routine large-animal mortalities |
| Composting | NDDEQ site permit required; not permitted for anthrax deaths | Year-round, multi-animal operations |
Which Agency Regulates Manure and Carcass Disposal in North Dakota
No single office handles every animal waste question in North Dakota — responsibility is split across a handful of state agencies depending on the issue.
- North Dakota Department of Environmental Quality (NDDEQ): Issues AFO/CAFO permits, regulates manure storage design, oversees composting site permits, and enforces water and air quality standards. NDDEQ covers the permitting requirements for composting.
- North Dakota Department of Agriculture (NDDA): Weighs in on butcher waste and processing-related disposal questions for meat plants and provides guidance for smaller operations. Permitting of incinerators is covered by the NDDEQ – Division of Air Quality.
- North Dakota Board of Animal Health: The point of contact for suspected anthrax, contagious disease, or captive cervid carcass questions.
- NDSU Extension: Publishes technical guidance on carcass disposal options but does not enforce state law.
When enforcement does happen, it’s rarely just one agency acting alone. In the Ward County feedlot case, the Sheriff’s Department said the investigation remains open, and the Department of Environmental Quality also has been notified about the case — a pattern that shows up whenever a disposal violation also raises environmental concerns.
Water Setbacks, Groundwater Protections, and Health Standards in North Dakota
North Dakota’s water protection rules sit underneath nearly every manure and carcass rule in the state. The baseline principle is simple: state law does not allow pollution of waters of the state, and that standard applies whether the source is a leaking manure pond or an improperly buried carcass.
Groundwater monitoring isn’t automatically required at every composting or storage site — it depends on soil type. Well sited, designed, and operated facilities probably do not need groundwater monitoring, though a site with coarse, sandy soils and a high-water table might need monitoring. That’s a meaningful distinction for producers in sandier regions of the state, where a site that would pass easily elsewhere might trigger extra scrutiny.
Setback distances for odor and water protection are measured with specific reference points, not vague estimates. The setback is measured from the nearest odor source, such as a manure storage structure, pens, animal housing or wet feed storage. The definitions behind those setbacks matter too — the residence does not need to be occupied, but must be habitable, and a public park is one established by the federal government, state, or a political subdivision, while a campground is public or private land used exclusively for camping and open to the public for a fee. For carcass burial specifically, veterinary guidance leans conservative. The disposal site should be away from residences, drinking water wells or shallow aquifers, a standard echoed in NDSU Extension’s own carcass disposal materials, which direct producers to choose ground well clear of wells, ditches, and flood-prone low areas.
Key Insight: Soil type can change your compliance obligations more than the size of your operation. A small operation on sandy, high-water-table ground may face more monitoring scrutiny than a larger operation on well-drained clay soil.
CAFO and Nutrient Management Plan Requirements in North Dakota
Concentrated Animal Feeding Operations face the most detailed layer of North Dakota’s waste rules, largely because they fall under both state permitting and federal Clean Water Act requirements. NDAC 33-16-01-01.1(1) incorporates 40 CFR 122.23 “Concentrated Animal Feeding Operations” by reference, which is how the federal NPDES framework flows into North Dakota’s own permit program.
A Nutrient Management Plan (NMP) is the centerpiece of CAFO compliance. It has to show how manure nutrients will be applied without overloading the soil or nearby water. Annual reporting obligations follow from that plan — an owner or operator of a CAFO has to submit an annual report on animal numbers, the amount of manure generated, manure transferred to another party, the number of acres of manure application, a summary of manure discharges, and whether the current Nutrient Management Plan was developed or approved appropriately.
Construction doesn’t end the oversight — it starts a new phase of it. NDDEQ staff conduct regular inspections during construction and at least annual inspections once operations begin to ensure compliance with permit conditions. Some permits go further on design, requiring features like clay liners: in the Herberg Dairy permit, the fact sheet outlined key permit features such as the use of clay liners in manure storage areas, according to reporting from KXNET.
Odor is also a regulated pollutant under a CAFO permit, not just a nuisance complaint. A permit does not authorize the discharge of any objectionable odorous air contaminant in excess of the limits set under NDAC Chapter 33.1-15-16, and if the department determines odors from a facility exceed those limits, the operator has to take steps within a reasonable time to control and reduce them. For full design specifications on storage volumes, setbacks, and pond construction, the North Dakota Livestock Program Design Manual is the technical reference NDDEQ staff use during permit review.
Penalties for Illegal Dumping, Missed Carcass Deadlines, and Water Violations in North Dakota
North Dakota doesn’t treat carcass abandonment or illegal manure discharge as a minor paperwork issue. The Ward County case is the clearest recent example of what enforcement looks like in practice: after a search warrant, officials removed 472 dead cattle from an open pit and “properly disposed of them according to state law”, while the underlying investigation into the operator’s original disposal practices continued.
A few patterns show up repeatedly in how violations get triggered and handled:
- Missed disposal deadlines. Letting a carcass sit past the 36-to-48-hour window, especially with a disease-related death, is treated as noncompliance on its own.
- Water contamination risk. Because state law does not allow pollution of waters of the state, a manure spill or improperly sited burial that reaches groundwater or surface water escalates quickly from a compliance note to an active investigation.
- Multi-agency response. As seen in the Ward County case, county sheriff’s offices and NDDEQ frequently coordinate once a report is filed, meaning a local complaint can bring in state environmental regulators.
- Permit condition violations. For CAFOs, missing an inspection, ignoring a depth marker reading, or failing to report manure transfers can jeopardize an existing permit.
Exact civil or criminal penalty schedules for water quality violations can change and vary by the specifics of a case, so if you’re facing a compliance question tied to a specific incident, that’s a conversation for an attorney or the agency directly rather than a general guide. For context on how North Dakota structures penalties for related animal-disposal violations in other areas of law, violations of the state’s chronic wasting disease carcass-disposal proclamation are treated as noncriminal infractions carrying a $200.00 fee — a useful comparison point, though it’s a separate rule from livestock manure and carcass law.
Common Mistake: Assuming a landfill will automatically accept a dead animal. Landfills that are permitted to take livestock carcasses aren’t required to, so calling ahead before you haul a carcass there can save you from a wasted trip and a missed deadline.
How to Confirm Current North Dakota Animal-Waste Rules With the Agencies
Because manure and carcass rules touch state statute, administrative code, and individual permit conditions, the fastest way to get a definitive answer is to go straight to the agency responsible for that piece of the puzzle.
- NDDEQ (Division of Water Quality): For AFO/CAFO permits, manure storage design standards, and composting site permits.
- NDDA: For questions involving meat processing waste, butcher waste, or general agricultural guidance.
- North Dakota Board of Animal Health: For anthrax, contagious disease, or captive livestock carcass questions.
- Your county extension office or NDSU Extension: For practical, non-regulatory guidance on choosing a disposal method that fits your operation.
If your operation involves livestock alongside other animals covered by separate state rules — working dogs, guard animals, or hunting activity on the same land — it’s worth checking related guides like hunting laws in North Dakota or wildlife removal laws in North Dakota so your full operation stays compliant, not just the manure and carcass side of it.
Important Note: This article summarizes general regulatory information current as of September 2026 and shouldn’t replace direct guidance from NDDEQ, NDDA, the Board of Animal Health, or an attorney. Permit conditions, setback distances, and enforcement practices can be updated, so confirm details with the relevant agency before making disposal decisions for your operation.
