Running a profitable feedlot means staying on the right side of dozens of environmental, animal welfare, and permitting regulations. This complete guide breaks down everything you need to know about cattle feedlot compliance, from federal permits to practical tech solutions that keep you audit-ready year-round.

What Is Feedlot Compliance and Why Does It Matter?

If your operation confines cattle for 45 days or more in any 12-month period in an area with no vegetation, the EPA classifies it as an Animal Feeding Operation (AFO). Scale that up past a certain animal threshold,s and you’re looking at a Concentrated Animal Feeding Operation, or CAFO. This designation triggers a whole suite of federal and state regulatory requirements.

Feedlot compliance is the process of meeting all environmental, operational, and animal welfare standards that apply to your specific operation. Why does it matter beyond the obvious legal obligation? 

For starters, the environmental stakes are real. Improperly managed manure contaminates groundwater with nitrates, fuels algae blooms in nearby waterways, and generates hydrogen sulfide emissions that can affect community health. According to the EPA, states with high concentrations of CAFOs experience an average of 20 to 30 serious water quality problems per year linked to manure mismanagement.

Beyond environmental protection, staying compliant keeps you in business. Violations can trigger hefty fines, mandatory corrective action plans, and in extreme cases, facility shutdowns. 

On the flip side, a solid compliance track record builds trust with neighbors, local municipalities, and buyers who increasingly demand sustainably sourced beef. Think of compliance not as a cost center, but as an investment in your operation’s long-term viability.

Demystifying the Core Regulations: MPCA, NPDES, and Local Ordinances

The alphabet soup of feedlot regulations can feel overwhelming. Let’s break down the three layers of oversight you’re likely dealing with: state pollution control agencies, federal permitting, and local conditional use rules.

MPCA Feedlot Rules and State Registrations

State-level pollution control agencies are your primary regulatory touchpoint. Minnesota’s Pollution Control Agency (MPCA) offers a useful model for how most states approach feedlot oversight. The MPCA regulates the location, design, construction, operation, and management of feedlots and manure handling facilities. Their two core concerns are preventing manure runoff into waterways and ensuring nutrient-rich manure is applied to cropland at agronomically responsible rates.

Nearly all feedlot owners must register with their state agency, though most smaller operations won’t need a full permit unless they’re building new facilities or expanding. In Minnesota alone, there are roughly 18,000 registered feedlots, with about 1,200 large operations holding state and federal permits. In states with significant livestock density, counties often share oversight duties through delegated programs. It means your local county feedlot officer may be conducting inspections and processing permits on behalf of the state agency.

NPDES and SDS Permits

At the federal level, the Clean Water Act’s National Pollutant Discharge Elimination System (NPDES) is the big one. If your feedlot qualifies as a CAFO and particularly a large CAFO with 1,000 or more cattle, you’re required to obtain an NPDES permit before any discharge reaches waters of the United States.

Most states are authorized to issue NPDES permits on behalf of the EPA, so you’ll typically work through your state environmental agency. The permit requires you to develop and implement a comprehensive Nutrient Management Plan (NMP) that covers the form, source, amount, timing, and method of manure application on each field. 

Some states also issue a State Disposal System (SDS) permit for operations that store or land-apply manure but don’t discharge to surface water. If you’re unsure which permits apply to your feedlot operation, start by contacting your state’s environmental agency or your local county feedlot officer.

Calculating Animal Units (AU) and Conditional Use Permits (CUPs)

Your regulatory obligations largely depend on how many Animal Units (AU) your operation houses. An Animal Unit is a standardized measure that accounts for differences in livestock size and waste output. Here’s how the common cattle categories break down:

Once your operation crosses certain AU thresholds, commonly 300 AU, 500 AU, or 1,000 AU, depending on your state, you may trigger additional permitting requirements. If you’re planning an expansion, most counties also require a Conditional Use Permit (CUP), which involves a public hearing and review by your county board. These local ordinances can impose setback distances from residences, roads, and water features that go beyond what the state mandates.

3 Key Focus Areas of Cattle Feedlot Compliance

These are the core foundations on which the credibility of your feedlot compliance depends:

Nutrient and Manure Management

Your Manure Management Plan (MMP) is the backbone of feedlot compliance. Getting it right means balancing nutrient application with crop needs while protecting water resources. Key areas to focus on:

• Liquid Manure Storage: All storage basins must be designed to contain the normal operating volume plus runoff from a 25-year, 24-hour rainfall event. Regular inspections for cracks, leaks, or freeboard issues are non-negotiable.
• Application Timing: Most states restrict winter application of manure on frozen or snow-covered ground due to high runoff risk. In Minnesota, for example, delaying fall application until soil temperatures reach 50°F or below helps reduce nitrate pollution.
• Setback Distances: Applying manure near sensitive areas, such as open tile intakes, sinkholes, lakes, and streams, is either prohibited or heavily restricted. Your MMP should map all sensitive features and define buffer zones.
• Agronomic Rates: Manure must be applied at rates that match crop nutrient uptake. Over-application is one of the most cited violations during inspections. For more on building an effective manure management strategy, consider how digital tools can help you document and track application records.

Air Quality and Odor Control

Odor complaints are one of the fastest ways to draw regulatory attention. The gases released during manure decomposition, particularly hydrogen sulfide and ammonia, are both a nuisance and a health concern.

• Hydrogen Sulfide Standards: In Minnesota, a feedlot violates state standards if hydrogen sulfide emissions exceed a 30-minute average of 30 parts per billion (ppb) twice in five days, or 50 ppb twice per year. Even at just 1 ppb, the gas is detectable, but at higher concentrations it causes headaches, nausea, and worse.
• Mitigation Strategies: Covering manure storage, using anaerobic digesters, maintaining proper ventilation in enclosed facilities, and managing pen surfaces to reduce standing moisture all help control emissions.
• Community Relations: Proactively addressing odor concerns builds goodwill. Keeping neighbors informed about manure application schedules and investing in odor-reduction technology can prevent complaints before they escalate to enforcement actions.

Animal Welfare and Antibiotic Usage

The regulatory landscape around animal welfare continues to evolve, and feedlot operators need to stay ahead of it.

• Space and Comfort: Adequate space allocation per head, clean and dry pen conditions, access to shade and water, and low-stress handling facilities all factor into compliance with both federal guidelines and buyer expectations.
• Antibiotic Oversight: Since June 2023, the FDA’s Guidance for Industry #263 requires that all medically important antibiotics previously available over the counter now need a veterinarian’s prescription. This means you must maintain a valid Veterinary-Client-Patient Relationship (VCPR) and keep thorough treatment records.
• Health Monitoring: Early detection of illnesses like bovine respiratory disease (BRD) is critical. Implementing a structured cattle health monitoring system helps you catch problems early, document treatments, and demonstrate compliance with welfare standards.

The Essential Feedlot Compliance Checklist for 2026

Whether you’re preparing for an inspection or just want to make sure nothing slips through the cracks, use this checklist as your operational baseline. Print it, share it with your team, and review it quarterly.

Registration and Permitting

• State Feedlot Registration: Confirm your registration is current. If you’ve added animals or changed your operation type, update it immediately.
• Expansion Permits: Planning to add pens or increase capacity? File for a new permit or CUP before breaking ground, not after.
• NPDES/SDS Permit Status: For operations at or above 1,000 AU, verify your federal/state discharge permit is active, and renewal dates are on your calendar.

Manure Management Plan (MMP)

• Documented Agronomic Rates: Your MMP must specify application rates based on soil tests and crop nutrient demands. Review these annually.
• Soil and Manure Testing Records: Keep lab results on file for a minimum of three years (or longer per your state’s requirements).
• Manure Transfer Records: If you’re selling or giving manure to neighboring farms, document who receives it, how much, and when.

Facility Maintenance

• Storage Basin Inspections: Inspect liquid manure storage structures routinely for cracks, leaks, seepage, and adequate freeboard. Document every inspection.
• Pen and Drainage Conditions: Ensure runoff from pens is properly directed to containment areas, not open waterways.
• Equipment Calibration: Manure application equipment should be calibrated annually to ensure accurate spreading rates.

Emergency Preparedness

• Spill Response Plan: Keep an updated protocol with contact information for your state’s duty officer and local emergency services.
• Mortality Management: Have a documented plan for handling mass animal mortality events that complies with state disposal regulations.
• Record Backup: Maintain digital backups of all compliance records. Paper-only systems are a liability during audits or emergencies.

Leveraging Technology to Simplify Your Feedlot Program

Managing the compliance checklist above with spreadsheets and paper logs isn’t just tedious; it’s a risk. A missed entry, a lost notebook, or a misfiled soil test can turn a routine inspection into a violation. 

Automated Record-Keeping

Modern feedlot ERP systems automatically log manure applications, herd health events, feed data, treatment withdrawals, and equipment maintenance, all timestamped and audit-ready. When an inspector asks for your last three years of manure transfer records, you pull them up in seconds instead of digging through filing cabinets. 

Conclusion
