Cultural Resource Historic Properties Treatment Plan for BK -1-072617 Colowyo Coal Company <br />3.4.4 Radiometric Sample Processing <br />All collected radiometric dating samples will be submitted to Beta Analytic for processing and <br />reporting. The samples will be collected and submitted per their guidelines. Tetra Tech will work <br />closely with the Beta Analytic to ensure timely processing and quality results. The dates will assist <br />placing the site into the regional cultural chronology and inform on specific subsistence practices <br />and landscape utilization patterns. <br />3.4.5 Protein Residue Analysis <br />If lithic tools and/or groundstone is recovered during testing or data recovery efforts, artifacts (or <br />a sample if assemblage is large) will be submitted to PaleoResearch Institute for protein residue <br />analysis. PaleoResearch Institute will handle the processing and reporting on the submitted <br />samples. Tetra Tech will work closely with the PaleoResearch Institute to ensure timely <br />processing and quality results. The data can contribute to questions of subsistence practice and <br />regional resource utilization. <br />3.4.6 Intrasite Spatial Analysis <br />Once all artifact analysis and sample processing has been completed and the results tabulated, <br />it will be compared to the spatial location and distribution of the collected material. Both the <br />horizontal and vertical aspects of the assemblage will be examined. The collected <br />geoarchaeological analysis and component(s) integrity assessment will also be incorporated into <br />the overall analysis. The analysis will help address the research question of intrasite spatial <br />patterning, site function, and organization as well as assisting in assessing cultural component <br />integrity. <br />3.4.7 Post -Analysis Artifact Handling <br />The site is located on privately held Colowyo land; therefore any recovered cultural material is the <br />property of Colowyo. As such, artifact curation is not required to conform to guidelines outlined in <br />36 CFR § 79 including curation of material at a federally recognized curation facility. The only <br />exception is human bone and/or funerary objects which will be handled under Colorado Revised <br />Statute 24-80-1301 et seq. <br />Colowyo will be offered the material once all analysis has been completed and final report <br />submitted and approved by OSMRE and OAHP. If Colowyo declines to take the artifacts, Tetra <br />Tech will discuss with OSMRE and OAHP appropriate places for either potential research <br />donations or curation. <br />3.5 Reporting and Dissemination <br />Several levels of reporting will be completed as part of the HPTP. <br />3.5.1 Evaluative Testing Technical Memorandum <br />Upon completion of evaluative testing, Tetra Tech will provide Colowyo, OSMRE, DRMS, and <br />OAHP with a technical memorandum report summarizing the results. The memorandum will <br />provide the testing results information as an explanation of what areas will be and won't be further <br />investigated under the Data Recovery part of the HPTP. The memorandum will include supporting <br />figures, maps, and photographs as appropriate. <br />Tetra Tech August 8, 2017 13 <br />
