The correspondence continues consultation initiated in July 2020 and is in response to our July 13, 2020 letter requesting additional information. We note that in accordance with the 1991 Memorandum of Understanding (MOU)between our agencies, because the technical revision may incorporate additional lands into the permit area or might otherwise alter previously approved permit conditions or mitigation measures, concurrence between our agencies is required due to the potential for impacts to cultural and/or historic resources. The technical revision proposes expanding mining operations. The technical revision application may incorporate additional lands into the permit area or might otherwise alter previously approved permit conditions or mitigation measures. As a result,impacts to cultural and historic resources must be evaluated. We appreciate the additional documentation you provided that includes the results of a class III cultural resource inventory. After review of the provided documentation,we do not object to the defined area of potential effects (APE). The cultural resource inventory identified four cultural resources in the APE. We concur with your finding that 5MF.9889 is not eligible for the National Register of Historic Places (NRHP)under any criteria. We also concur with your finding that isolated finds 5MR.9867, 5MR.9876, and 5MF.9877 are not eligible for the NRHP under any criteria. Based on the documentation provided, we concur that your finding of no historic properties affected[36 CFR 800.4(d)(1)] is appropriate for the subject undertaking. Should unidentified archaeological resources be discovered in the course of the project,work must be interrupted until the resources have been evaluated in terms of the National Register eligibility criteria(36 CFR 60.4) in consultation with our office pursuant to 36 CFR 800.13. Also, should the consulted-upon scope of the work change,please contact our office for continued consultation under Section 106 of the National Historic Preservation Act. We request being involved in the consultation process with the local government, which as stipulated in 36 CFR 800.3 is required to be notified of the undertaking, and with other consulting parties. Additional information provided by the local government or consulting parties might cause our office to re-evaluate our eligibility and potential effect findings. Please note that our compliance letter does not end the 30-day review period provided to other consulting parties. • RYCO LO R ADO.OR HISTORY COLORADO CENTER 1200 BROADWAY DENVER CO 80203
