Right to Farm Act (RTFA) and GAAMP

This is a general overview of Michigan’s Right to Farm Act and Generally Accepted Agricultural and Management Practices (GAAMPs).  The GAAMPs were developed for specific farming operations, and they may or may not be applicable to your farm.

INTRODUCTION

Think about how your neighbors might view your agritourism operation(s).  For example, is there a lot of traffic generated, when, and how often?  Are there noises from tractors or other farm equipment?  Are there animal noises or smells?  

Though your neighbors may be generally supportive of what you are trying to do, they may not appreciate the added noises, odors, traffic, or people visiting your farm.  Each year, the Michigan Department of Agriculture and Rural Development (MDARD) receives several hundred complaints about farms.  Michigan’s Right to Farm Act may or may not protect you depending on your farm or type of farm operation. 

THE RIGHT TO FARM ACT (RFTA)

According to the National Agricultural Law Center, all fifty states have enacted right-to-farm laws. These laws seek to protect qualifying farmers and ranchers from nuisance lawsuits filed by individuals who move into a rural area where normal farming operations exist, and who later use nuisance actions to attempt to stop those ongoing operations. While the overall statutory schemes might be similar, each state’s laws can differ widely.

Michigan’s Right to Farm Act (RFTA) was enacted in 1981 and is recognized nationally as a model for resolving disputes between farmers and neighbors or local governments when they allege that practices on the farm constitute an actionable nuisance. Michigan’s RFTA provides a broad definition of a farm, its operations, and its products.  

Its definitions include (see Rule for complete definitions):

  • “Farm” – land, plants, animals, buildings, structures, ponds, machinery, equipment
  • “Farm Operation” – various activities that occur during the process of production, harvesting, and storage (see Rule for specific examples)
  • “Farm Product” – plants and animals useful to human beings produced by agriculture (see Rule for specific examples)
  • “Generally Accepted Agricultural and Management Practices (GAAMPs)” – (see list of practices defined)
  • “Person” means an individual, corporation, partnership, association, or other legal entity. 

Note: In 1998, the Michigan Agricultural Processing Act was enacted, offering a suite of nuisance protections to operations engaged in processing of agricultural products, including food for human consumption and animal feed. This Act differs from the Right to Farm Act.

THE RFTA AND GAAMPs

In addition to defining “what constitutes a farm”, the RFTA authorizes the Michigan Commission of Agriculture and Rural Development (MDARD) to develop and adopt Generally Accepted Agricultural and Management Practices (GAAMPs) for farms and farm operations in Michigan.  These GAAMPs define socially and environmentally responsible farming practices.  The GAAMPS were developed by technical advisory review committees and presented to MDARD for review and approval.

Farmers who voluntarily follow these GAAMPs are offered some protection from nuisance lawsuits over matters such as noise, odor, dust and even operating a farm market as long as the farmers comply with the practices.  Conformance with GAAMPs is a defense against nuisance litigation.

Michigan’s GAAMPs cover the following operational areas: 

  • Care of Farm Animals 
  • Cranberry Production 
  • Farm Markets 
  • Irrigation Water Use 
  • Manure Management and Utilization 
  • Nutrient Utilization 
  • Pesticide Utilization and Pest Control 
  • Site Selection and Odor Control for New and Expanding Livestock Facilities

WHAT IS MDARD’S RIGHT TO FARM PROGRAM AND HOW CAN IT HELP YOU?

The Right to Farm Program within the MDARD can assist farms of all sizes by reviewing the farm operation’s conformance with the GAAMPs. Though most of these requests are for livestock and farm animals, MDARD also reviews a variety of operations. MDARD works with the farm to evaluate all applicable management practices and facility designs, as well as the proximity to non-farm neighbors and existing land use considerations.  

There are two types of reviews; both are done at the farmer’s request.

  • Proactive – Review is done in advance at the farmer’s request to determine the farmer’s compliance with GAAMP, typically done when expanding or adding an operation.  
  • Upon Complaint – Investigation is initiated upon receipt of a complaint.  Staff will review the farmer’s operation to determine compliance with the GAAMP as part of MDARD’s response.

According to MDARD, on-farm production agriculture is the foundation of Michigan’s $104.7 billion food and agriculture industry, with livestock facilities generating more than $8.2 billion in annual cash receipts.  Yet, there are increasing social and environmental concerns regarding agricultural production in Michigan, especially animal agriculture. These proactive reviews are important not only to the farmer but to the state. They allow the industry sector to grow in a responsible way that minimizes nuisance to nonfarm neighbors.

COMPLIANCE REQUIREMENTS

How are prospective neighboring property buyers aware of the farm and its operation?

The RFTA states that a seller of real property located within 1 mile of the property boundary of a farm or farm operation may voluntarily make available to the buyer the following statement: “This notice is to inform prospective residents that the real property they are about to acquire lies within 1 mile of the property boundary of a farm or farm operation. Generally accepted agricultural and management practices may be utilized by the farm or farm operation and may generate usual and ordinary noise, dust, odors, and other associated conditions, and these practices are protected by the Michigan right to farm act.”  286.473c Property subject to disclosure; contents of statement. Sec. 3c. (1).

Whose rules do you follow when the RFTA and GAAMPs conflict with local zoning ordinances?  

The RTFA will preempt local zoning ordinances when such ordinances conflict with GAAMPs approved by MDARD.  Without this pre-emption, many local ordinances might be passed that severely restrict farming operations.  

Does RFTA exempt farmers from obtaining building permits for agricultural buildings?

Certain agricultural buildings are exempt from state requirements to obtain building permits before their construction.  The state construction code, not the Michigan RFTA, provides farmers with this limited exemption.  Michigan Farm Bureau has helpful FAQs on this area:  https://www.michfb.com/agriculture/farming-resources/land-use-regulation/building-permit-exemption

CASE LAW AND LEGAL IMPLICATIONS

Legal cases in Michigan have included these rulings:

  • The RTF law does not prevent political subdivisions from regulating noncommercial farms.  Brown v. Summerfield Twp., No. 304979, 2012 WL 3640330 (Mich. Ct. App. Aug. 23, 2012); Shelby Twp. v. Papesh, 704 N.W.2d 92 (Mich. Ct. App. 2005).
  • The RTF law does not prevent political subdivisions from regulating activities that do not meet the statutory definition of “farm” or are not necessary for the production, harvesting, or storage of “farm products,” such as composting, construction of buildings for an unrelated use, or auctions.  Charter Twp. of White Lake v. Ciurlik Enterprises, No. 326514, 2016 WL 2772160 (Mich. Ct. App. May 12, 2016); Cty. of Mason v. Indian Summer Co-Op Inc., No. 301952, 2012 WL 3536789 (Mich. Ct. App. Aug. 16, 2012).

  • RTF protections do not extend to a farming operation established after a change in zoning.  Jerome Twp. v. Melchi, 457 N.W.2d 52 (Mich. Ct. App. 1990).
  • The RTF law does not exempt farms from violations of the Natural Resources and Environmental Protection Act.  King of the Wind Farms Inc. v. Michigan Comm’n of Ag, No. 257097, 2005 WL 3556150 (Mich. Ct. App. Dec. 29, 2005).
