Last month, the Michigan Public Service Commission (MPSC) announced the final rules to detect stray voltage on-farm. Entitled, "Rules and Regulations Governing Animal Contact Current Mitigation," these uniform procedures and processes took almost six years to complete.

The rules are the result of collaboration between the dairy industry — including representatives from Michigan Milk Producers Association and Dairy Farmers of America, as well as Michigan State University, Michigan Farm Bureau, and many others.

MPSC’s action formally adopts the rules that provide for:

  • A definition of stray voltage consistent with engineering standards.
  • Measuring animal contact voltage.
  • Action required to mitigate animal contact current.
  • Requesting an investigation.
  • Appointment of experts.
  • Requesting a contested case hearing.
  • A protocol to evaluate utility contribution to animal contact current.
