Code of Federal Regulations Title 7. Agriculture § 7.301.38–8 Costs and charges

The services of an inspector   4 during normal business hours, Monday through Friday, 8 a.m. to 4:30 p.m., will be furnished without cost to persons requiring the services. The United States Department of Agriculture will not be responsible for any other costs or charges.

 Persons performing the inspection must be able to recognize rust-susceptible varieties of Berberis, Mahoberberis, and Mahonia. Inspectors must work side by side, 10 to 20 feet apart, and walk outward, away from the nursery, a distance of one half mile measured from the edge of the nursery, and observe all plants growing in the half-mile band. The distance between the inspectors may vary within this range depending upon the visibility of plant growth. In areas with low brush and flat terrain, the inspectors may be the maximum distance of 20 feet apart if they can observe all plants growing within ten feet of them. In areas of high plant growth or hilly terrain, the inspectors must be closer together due to limited or obstructed visibility. Each inspector must observe all plants growing between themselves and the mid-point of the distance between themselves and the next inspector. This process must be repeated so that the entire band, measured from the border of the nursery to the circumference of an imaginary circle having the nursery as its mid-point, is visually inspected in this manner.
