479B.33  Farmland improvements.
  A landowner or contractor may require a representative of the pipeline company to be present on site, at no charge to the landowner, at all times during each phase and separate activity related to a farmland improvement within fifty feet of either side of a pipeline. If the pipeline company and the landowner or contractor constructing the farmland improvement mutually agree that a representative of the pipeline company is not required to be present, the requirements of this section are waived in relation to the farmland improvement which would have otherwise made the requirements of this section applicable. A farmland improvement includes, but is not limited to, the terracing of farmland and tiling.
