RULE 2 - PERMITS
On January 2009, Metcalf Archaeological Consultants, Inc. conducted a Class III cultural
resource inventory within portions of the mine permit areas in T6N, R87W, Sections 34 and 35;
and T5N, R87W, Sections 2 and 3. Survey results are summarized in an Exhibit (Exhibit
2.04.4-E2, Cultural Information — Stockpile and Portal Areas (confidential), which contains the
Metcalf Archaeological Consultants, Inc. Report, titled A Class III Cultural Resources Inventory
of the Proposed Twentymile Coal Company Sage Creek Stockpile and Portal Areas, Routt
County, Colorado (Metcalf Archaeological, 2009b). The survey consisted of a Class III cultural
resource investigation for the proposed PSCM stockpile and portal areas, which accounts for a
small portion of the entire PSCM permit area, but the majority of the proposed surface
disturbance footprint. No archaeological materials were discovered during the inventory and a
finding of no historic properties affected was recommended for the project.
File searches for this field effort were conducted through the OAHP Compass database on
November 2008. The database indicates that eight cultural studies have occurred within the
sections covered in the inventory. All projects were cultural resource inventories for well line
and access roads, transmission lines, drill sites, and investigation of coal leases. Numerous other
inventories, most related to coal mining, seismic exploration, and powerline construction have
been conducted in nearby sections. Most are either linear or small block survey.
An additional Class III Survey of a small additional area to be disturbed by planned surface
activities was completed in July 2009. Survey results are included in a letter report titled;
"Twentymile Coal Company Sage Creek Portal Project: A Class III Cultural Resources
Inventory, Routt County, Colorado", in Exhibit 2.04.4-E2, Cultural Information.
For anticipated future subsidence areas, Metcalf Archaeology developed and submitted a
proposed methodology for Class I and limited Class II surveys to address SHPO requirements,
but limit the associated work efforts where the only impact would be surface subsidence, and
where the potential of occurrence for cultural resource values would be limited, based on prior
surveys of the area and the resulting identified patterns of use and occupation. The proposed
methodology is outlined in a report titled; "Class I Inventory and Proposed Class 11 Methodology
for Peabody Coal Company's Sage Creek Subsidence Expansion Area, Routt County, Colorado,
which is included in Exhibit 2.04.4-E2, Cultural Information.
