SENT BY~FSP&T, LLC <br /> <br />3. relative to the western shoreline of the Late Cretaceous-age seaway (that covered <br />• _ essentially all of Colorado during the deposition of the Fort Hays Member), the proposed <br />RGPCC site is sufficiently distant from the prevailing sediment-supply to avoid <br />contamination by siliciclastic muds (thus, the majority of the sediments observed are <br />detri[us-free limestones) -- additionally, north to south geostrophic ("longshore") currents <br />along the western shoreline of the seaway, documented from abundant stratigraphic <br />evidence (in Colorado, Wyoming, Montana, and Utah) "buffered" the offshore regions of <br />the Western Interior (= central limeslahe-dnrginared belt) from river-bom plumes of fine- <br />grained derritus; <br />3. the position of the proposed RGPCC quarry on the Trans-Continental Arch hasement <br />structure (actively uplifted during the Late Cretaceous) provided additional condensation <br />of sediments during deposition of the Fort Hays Member, and effective bypass or <br />removal of fine-grained siliciclastic sediments (e.g. tnudstone) due to shallower, higher <br />energy wa[er depths -resulting in purer lime muds than found in coeval beds in the <br />surrounding regions of Huerfano, Fremont, and EI Paso counties; <br />4.. existing overburden an the proposed RGPCC quarry lands ranges from 0.0 m [0 10.0 <br />m [yielding a t0.g:1 overburden ratio): ranking among the best in any phase of the <br />mining industry, greatly reducing the need for extensive blasting and removal of non- <br />economic materials, and thou anendan[ storage in large, unsightly piles for long periods. <br />• <br />• 1993 <br />
