Animal Waste Disposal Laws in New York: What Livestock Owners Must Know
September 29, 2026
If you own livestock in New York, the clock can start ticking the moment an animal dies. Once a peace officer, police officer, or a representative of the state’s agriculture commissioner directs you to act, you have 72 hours to bury or otherwise dispose of the carcass in a sanitary manner. That single deadline sits at the center of New York’s animal waste disposal laws, but manure storage, land application, and CAFO permitting bring their own separate set of rules.
This guide breaks down what farm owners, homesteaders, and small acreage operators actually need to do to stay compliant, who enforces each piece of the puzzle, and what happens if you don’t follow through. Whether you’re managing a backyard flock or a 700-cow dairy, the requirements below apply to you in some form.
What New York Requires for Livestock Waste and Dead-Animal Disposal
New York splits animal waste regulation into two lanes. The state’s animal laws that govern household pets don’t apply here — dead-animal disposal and manure management fall under agricultural and environmental statutes instead, primarily the Agriculture and Markets Law and the Department of Environmental Conservation’s solid waste and water regulations.
The carcasses of large domestic animals, including but not limited to horses, cows, sheep, swine, goats and mules, which have died otherwise than by slaughter, shall be buried at least three feet below the surface of the ground or otherwise disposed of in a sanitary manner by the owner of such animals, whether the carcasses are located on the premises of such owner or elsewhere. That means the law covers you whether you raise a couple of dairy goats or run a full cattle operation — check our goat ownership laws in New York guide if small ruminants are part of your setup.
Disposal must be completed within seventy-two hours after the owner is directed to do so by any peace officer, acting pursuant to his special duties, police officer, or by a designated representative of the commissioner. The statute carves out one exception: this section shall not apply to animal carcasses used for experimental or teaching purposes.
Pro Tip: Don’t wait for an official directive before acting. Farm mortality specialists recommend deciding on a disposal method as soon as an animal dies, since delayed burial or composting makes carcass handling significantly harder.
Manure Storage, Stockpiling, and Land-Application Rules in New York
Manure rules scale with farm size. Smaller operations — including backyard chicken keepers and those raising a few roosters under local rooster ownership laws — generally answer to local nuisance and public health codes rather than state permits. Larger operations face a much more detailed compliance framework administered through the state’s Concentrated Animal Feeding Operation program.
For permitted farms, professional engineers licensed in New York State are required to design and certify all waste storage facility projects. Per New York’s CAFO permit, these waste storage facilities must be able to hold the designed volume of manure and process waters from the farm, plus the precipitation expected to be contributing to the storage during a 100-year, 24-hour storm.
Land application isn’t unlimited either. The CAFO permit sets maximum thresholds for single applications at 20,000 or 27,000 gallons per acre in any 7-day period, depending on the nutrient plan. On top of that, farms must sample soil for nutrient values every three years versus every five years under the federal standard. Winter application carries extra scrutiny, since the state maintains revised winter and wet weather manure spreading guidelines to reduce water contamination risk.
| Farm Size (Dairy) | CAFO Classification | Key Requirement |
|---|---|---|
| Under 300 cows | Not typically CAFO-permitted | General nuisance and water quality laws apply |
| 300–699 cows, non-discharging | Medium CAFO | Comprehensive Nutrient Management Plan required |
| 700+ cows, non-discharging | Large CAFO | Same, with stricter monitoring |
New York has approximately 500 CAFO-permitted farms, which results in regulating over 50% of the manure produced in the state, according to the NYSDEC’s manure storage guidance.
How You Must Dispose of Dead Livestock Carcasses in New York
Once an animal dies, you generally have four options: burial, a removal service, incineration, or composting. A removal service will take away a dead animal within the 72-hour window, but that route can be expensive and, at times, unreliable — the other options are burial, incineration, and composting, according to livestock mortality guidance covering New York farms.
If you bury on your own land, specific spacing rules apply. Only three large animals may be buried per 10-foot-by-10-foot pit, and pits must be separated by at least 10 feet, with a maximum of 50 large carcasses per acre. Trenches are permitted in mass mortality situations, and these legal requirements were recently outlined in NYSDEC solid waste rules under 6 NYCRR 363-2.1(b).
Composting is a increasingly common alternative, and it comes with its own technical standards. Follow this sequence for an effective mortality compost pile:
- Select a site away from neighbors and near where you already spread manure.
- Build a base layer that can absorb leachate and allow air to enter — woodchips work better than sawdust.
- Cover the carcass with about 2 feet of material on all sides.
- Monitor pile temperature; a correctly built pile reaches 130 to 170 degrees Fahrenheit within 12 to 24 hours, and holding that heat for five days kills pathogens.
- Allow six to nine months for the compost to fully mature before use.
State rules also limit off-site composting. Under State law, up to 10 carcasses per year can come from off-site sources, and the animal carcasses must be placed within the compost pile on the day received. To handle additional off-site animals, the farm must obtain a solid waste management facility registration under 6 NYCRR Part 361-3.2(b)(3). For guidance specific to your operation, the New York State mortality disposal guidance walks through each method in more detail. If you’re weighing how carcass rules differ for wildlife versus livestock, our roadkill laws in New York article covers the wild-animal side of that comparison.
Which Agency Regulates Manure and Carcass Disposal in New York
Two state agencies split enforcement. The New York State Department of Environmental Conservation oversees CAFO permitting, on-farm burial, and solid waste registration — on-farm burial is regulated by the New York Department of Environmental Conservation. In New York, the DEC administers both the federal Clean Water Act permit and the state Environmental Conservation Law permit for CAFOs.
The Department of Agriculture and Markets enforces the dead-animal disposal statute itself, works with peace officers on 72-hour directives, and publishes mortality-management guidance for producers. Cornell’s PRO-DAIRY program and the Nutrient Management Spear Program provide the technical backbone many farms rely on, including AEM Certified Planners who draft nutrient management plans.
Enforcement doesn’t stop at farm-specific rules, either. Animal cruelty investigations sometimes intersect with waste violations when neglect is involved — see our overview of animal cruelty laws in New York for how that overlap works. Wildlife carcasses and nuisance animal removal fall under a separate DEC division, detailed in our nuisance wildlife laws in New York guide. In New York City, a separate municipal health code provision and 311 reporting system handle dead-animal reports on private property.
Water Setbacks, Groundwater Protections, and Health Standards in New York
New York’s CAFO permit is deliberately stricter than the federal floor. New York CAFOs must maintain no discharge from their production areas through a 100-year, 24-hour storm, compared to the federal no-discharge standard, which is for a 25-year, 24-hour storm. Manure storage structures also carry engineered groundwater safeguards: standards include measures to protect against structures overtopping, and they require maximum fill markers to help ensure that safety volume requirements are maintained.
That engineering has a track record. To date, there has been no evidence of a certified manure storage contributing to an impact to groundwater in New York, according to Cornell’s CAFO FAQ resource. Still, the state treats any breach seriously: any impact to Waters of the State is considered a significant violation of the Environmental Conservation Law and is subject to substantial penalties and/or fines.
Water withdrawal for agricultural use also has a threshold. Water withdrawal regulations require a water withdrawal permit if an agricultural facility that did not report prior to February 15, 2012 is withdrawing water equal to or in excess of an average of 100,000 gallons per day in any 30-day consecutive period. Farms that registered earlier must still report annually — that report is due by March 31 of each year and is required regardless of the amount of water withdrawn during the reporting year, per the DEC’s agricultural water withdrawal program.
Important Note: Enforcement isn’t purely theoretical. A 2018 legal review noted that DEC’s map shows two medium and two large CAFOs in Saratoga County alone, and similar concentrations across Washington, Rensselaer, and Columbia counties — meaning water-quality oversight touches a meaningful share of upstate farmland.
CAFO and Nutrient Management Plan Requirements in New York
If your farm qualifies as a CAFO, a Comprehensive Nutrient Management Plan isn’t optional. New York CAFOs must utilize an AEM Certified Planner, whereas no professional certification is required by the federal CWA CAFO Rule. That plan has to address feed storage, manure storage, milking centers, and barnyards, and document performance to determine the systems are functioning properly.
New York layers on several requirements the federal rule doesn’t demand. Beyond the storm-storage standard already covered, New York CAFO permitted farms must follow an integrated system of NRCS Conservation Practice Standards for management of nutrients throughout their farmsteads and fields. New York CAFOs must also develop and maintain facility-specific winter and wet weather application procedures and identify low-risk fields for winter application in an emergency, and farm staff must be present and monitor active waste transfers from the production area while material is being transferred.
Which permit a farm chooses matters for transparency. The federal permit requires farms to file a nutrient management plan with the state and allows for limited discharges of raw waste, while the state law allows no discharge but doesn’t require filing a nutrient management plan, though the farm has to keep one on site to show during DEC inspections. An investigation from New York Focus found that not a single farm was registered under the stricter federal requirement, with hundreds instead switching to the state permit, under which manure management practices aren’t subject to public review. DEC has disputed the characterization that this makes oversight weaker.
Penalties for Illegal Dumping, Missed Carcass Deadlines, and Water Violations in New York
Missing the carcass-disposal deadline carries real consequences, though they’re calibrated differently than you might expect. Notwithstanding section forty-one of the Agriculture and Markets Law, any violation of the dead-animal disposal statute constitutes a violation rather than a misdemeanor — a lesser classification, but still a chargeable offense with fines attached.
Dumping-related penalties can be considerably steeper in municipal jurisdictions. New York City’s code, for example, treats commercial dumping of manure, refuse, or debris on streets, lots, or waterways as a misdemeanor: a person who violates that provision while engaged in commercial activities is liable upon conviction to a fine of $4,000 for the first offense and $9,000 for any subsequent offense, or imprisonment not to exceed 90 days. That figure comes from the NYC Administrative Code’s dumping prohibition.
Water violations tied to CAFOs escalate further because they trigger the Environmental Conservation Law’s broader enforcement framework, not just a single statute. Any impact to Waters of the State is subject to substantial penalties and/or fines under the ECL, and real incidents illustrate why the state takes this seriously — one of the state’s largest facilities was responsible for two manure spills in a single week, one of which entered Cayuga Lake and was found precariously close to local water supplies, according to reporting from Waterkeeper. DEC’s own enforcement guidance for water pollution cases, outlined in its Water Pollution Control Enforcement Policy, governs how those civil penalties get calculated.

How to Confirm Current New York Animal-Waste Rules With the Agencies
Regulations like these get amended, and CAFO permit terms are reissued on a schedule, so it pays to verify details before you act on anything in this guide. Start with the agency that matches your question:
- NYSDEC Division of Water — for CAFO permits, manure storage design standards, and water withdrawal reporting.
- NYS Department of Agriculture and Markets — for dead-animal disposal directives and farm mortality guidance documents.
- Cornell PRO-DAIRY and your county Soil and Water Conservation District — for nutrient management plan technical support and AEM Certified Planner referrals.
- NYC 311 — for reporting a dead animal on private property or clusters of dead animals for possible disease testing within city limits.
Most regional DEC offices maintain direct phone lines for farm compliance questions, and Ag & Markets regional staff can clarify whether your operation needs a solid waste registration before you build a compost pile larger than the on-farm exemption allows. If you keep other animals covered by overlapping New York statutes — everything from poultry to livestock — cross-check those rules too, since disposal obligations often apply regardless of species or flock size.
Pro Tip: Keep a written record of every disposal event — date, method, and any agency communication. If DEC or Ag & Markets ever questions your compliance history, documentation is your fastest way to resolve it.
