RE: Sunflower Energy Corporation's Nlue Ribbon Mine Plan
Dear A1r. Townsend:
•D LAND RECLI .. ^ ~.• ~..~ .
nrnT. OF NA. ...~ ~..ii.
The Office of Surface Mining (OSht) has completed the Apparent Completeness
Review of Che cultural resources portions of [he R1ue Ribbon Subsurface Nine
Plan. On the hasis of a Limited cultural resource survey~my staff has found
no sites which are eligible for listing in the National Register of Historic
Places that will he directly impacted by mining opera[ions. The rzview,
however, has determined that lands which have the potential for post mining
subsidence have not been inves[iga[ed Eor cultural resources.
We believe that approval of this mine plan wLth the following stipulations
will leave no effect nn k~town cultural resources. It is the intention of this
office to conduct an inhouse sample cultural resource-oriented survey of these
potentially affected lands before July 1981. If the survey locates cultural
resources, additional consultation with your office will he required.
Proposed Stipulations
A. If cultural materials are located as a result of [he survey, they will be
recorded by the Office of Surface Mining and [he documentation will be turned
over to [he applicant. Within 60 days of receiving completed survey forms,
t)ie applicant in conjunction with OSM, the Forest Service, and the State
Ili static Pre servatinn Officer (SIIY~) will request a determination of
eligibility. Addit~ionaLiy, it is the responsibility of the applicant to
formulate within 90 days of receiving, [he OSM survey forms a mitigation plan
for eligible sites threatened by potential subsidence acceptable to the above
agencies and the Advisory Council for 1{isCoric Preservation. Preservation and
or mitigation of impacted cultural resources is the responsibility of the
applicant.
6. If previously unidentified cultural resources should he_ discovered during
mining operations, the operator shall insure [hat the site is no[ disturbed
and shall immediately cease land disturbing activities within the vicinity of
LJ ue site and notify the regnlacory authority. The operator ,hall ensure that
the re.aou~ee(s) is properly cvaluaCZd in terms of. Lhn National Register (36

National Regislcr in consultation with the Regula[orv Authority and the SHPO,
