Please refer to the attached letter. If you have any questions, feel free to contact me. <br />Sincerely, <br />On Thu, Sep 28, 2017 at 11:35 AM, Tennyson, Tony (Colowyo) <ttennyson@tristategt.org> wrote <br />Zach, <br />Per our meeting we had some time back to with OSMRE, yourself and Tri-State to discuss the Historic Properties <br />Treatment Plans (HPTP) for discovered eligible cultural resource sites, it was determined that we could submit a <br />preliminary data report once mitigation on the ground was complete. This preliminary report if agreed upon by all <br />agencies would allow Colowyo to recommence construction of the Collom Haul Road within the 100' buffer zone <br />established for the discovered sites. That being said, Tetra Tech has finished the excavation work and data collection <br />on the ground for sites MK -1-02317 and MK -2-02317. The HPTP for these sites was submitted and approved by the <br />Division under MR -179. 1 have attached the preliminary report for these two sites for your review. <br />As stated in the report, the field portion of the HPTP for these two sites has been completed and all data potential at the <br />site has been exhausted. We would like to begin construction in those areas again on October 9, but we will not <br />recommence ground operations until approval has been granted from the Division. <br />I would appreciate a timely review as operations would like to restart working in that area next week. If you have <br />questions please give me a call. <br />Tony Tennyson <br />Senior Environmental Engineer <br />Tri-State Generation and Transmission Association, Inc. <br />Office: 970.824.1232 <br />ttennyson@tristategt.org <br />https://mail.google.com/mail/b/AAYagpU-6N3_OpM U23zvEgKh6U l2iTsjRJ27uYod7ZJ-VUoXy5CV/u/O/?ui=2&ik=deb7fOcd20&jsver=EaI L6uzdl9M.en.&... 1/2 <br />
