Wis. Admin. Code Department of Natural Resources NR 406.08
The geographic center of the FCPC Class I area, as identified in s. NR 400.02(66m), was determined by finding the center of a rectangle placed around the outer most portions of the Class I area. The 22.25-mile radius was determined by adding 10 miles to the distance of the outermost portion of the FCPC Class I area from the geographic center of the FCPC Class I area.
The Department has determined that any source wholly located outside of a circle with a radius of 74.25 miles from the geographic center of the FCPC Class I area is not within 62 miles of the FCPC Class I area. The 74.25-mile radius was determined by adding 62 miles to the distance of the outermost portion of the FCPC Class I area from the geographic center of the FCPC Class I area. It is the Department's intent that this circle be used as a screening tool for determining applicability of this subsection, and evidence that a source is wholly outside of this circle will be accepted as proof that the source is not within 62 miles of the FCPC Class I area.
The relationship between the State of Wisconsin and the Forest County Potawatomi Community with regard to the FCPC Class I area is established in a 1999 Class I Final Agreement. Dispute resolution follows a process agreed to by the Department and the Forest County Potawatomi Community pursuant to the Final Agreement.
The Final Agreement and a map showing the approximate 22.25-mile and 74.25-mile radii are available from the Department upon request, or may be found on the Department's web site.
