Cultural Resource Historic Properties Treatment Plan for BK -2-082818 Colowyo Coal Company
A professional technical mitigation report will be produced that meets all OSMRE, DRMS, and
OAHP standards and requirements. The report will be organized and scaled as appropriate to
clearly present the information gathered in the field and resulting laboratory analysis. The general
report outline will be the following:
• Overview of the Project
• Historic Context of the Site including Archival Research Results
• Review of Research Design
• Mitigation Methodology
o On -Site
o Off -Site
• Mitigation Results
o Surface Component Documentation
o On -Site Excavations
o Artifact Review, Discussion, and Analysis
• Analysis of All Findings Compared to Research Design
• Conclusions and Discussion
• Appendices (as appropriate)
Additionally, an updated OAHP site form will be completed for archiving. The report will be
produced for formal review and acceptance by OSMRE, DRMS, and OAHP. A draft version of the
full report will be provided to the agencies for review and comment. Upon receipt of comments,
Tetra Tech will produce a final report with appropriate hard and electronic copies will be produced
and submitted.
3.4.3 Professional Presentations and Information Dissemination
Tetra Tech's cultural resource staff may choose to disseminate the treatment results via oral
presentation(s) to the Rocky Mountain Anthropological Society Meetings and/or Colorado
Archaeological Society meetings as part of our duty to share work with our professional
community.
Appropriate information will be redacted from any presentations. Colowyo, OSMRE, DRMS and
OAHP will be dually acknowledged for their support and assistance toward the successful
execution of all work.
4.0 CLOSING
Site BK -2-062518 was discovered during archaeological construction monitoring. The discovery
is located on the south side of a haul road overpass culvert that is being constructed for the
Project. The site currently consists of a single possible thermal feature. Tetra Tech recommended
the site as eligible for inclusion on the NRHP under Criterion D pending further investigation. The
Project activities will remove the site as part of the culvert construction and Colowyo cannot modify
the work to avoid the site. Therefore, the project will cause an adverse effect and the presented
HPTP is to ensure the data recovery work is completed in conformance with the process outlined
in 36 CFR § 800 and Exhibit 5, Item 3 -Cultural Resource Protection Plan for the Collom Mine
Expansion is completed in a timely manner.
