'~~ • • Page 4 <br />State of Colorado <br />Mined Land Reclamation <br />Exhibit D (a) explains that quarry cuts are numbered <br />in sequence of removal (1, 2, 3, 4, 5, 6, etc.). <br />Even and odd-numbered cuts are in different locations <br />to facilitate overburden placement in the adjacent <br />worked-out cut while production removal of limestone <br />can proceed from a cut in the other location (cuts <br />indicated on pcc-1387). Thus overburden from cut 3 <br />can be placed directly into cut 1, cut 4 into cut 2, <br />cut 5 into cut 3, cut 6 into cut 4, etc. <br /> An effort has been made to furnish as much infor- <br /> mation about this long range quarry operation as <br /> currently anticipated. Contingencies as mentioned <br />1~e in paragraph (e) Exhibit D are particularily applicable <br /> <br />~ to the mining of low value materials from this quarry. <br />~~ <br />~~- ~ Deposits in the Portland East and Concrete quarries <br />F"j lack sufficient exploration to detail quarry operation. <br />~~er~% In view of these contingencies it is not considered <br /> practical or meaningful to attempt to establish <br /> mining details beyond the 20 to 25 years indicated. <br />ge2~ Experience with the operation of quarries of this <br />C~rl~ nature indicate the probability that frequent amend- <br />/ ments to the mining and reclamation plans as well as <br />r• the regulations will be necessary. Future inspections, <br /> changes in surety, etc. are expected to indicate well <br /> in advance the need for such amendments. <br /> 4. Paragraph C reference to possible future rerouting <br /> of Bear Creek prior to development of the Portland <br /> ' West quarry. It was mentioned that rerouting of <br /> this small creek would be beneficial. Speculation <br /> ` or alternate routing should perhaps not have been <br /> mentioned in the application as a detail study of <br /> all features would be most timely in about 20 years. <br /> We are not fully certain at this time whether the <br /> Portland East or Concrete quarries will be operated <br /> first after the Portland West quarry nears completion <br />V. Exhibit E - Reclamation Plan. <br />The slope of original surfaces vary from flat to <br />vertical. Map pcc-1387 shows the contour (5 ft. <br />intervals) of the present surfaces and is con- <br />sidered to be the only practical way to present <br />this information. Exhibit E (g) (i) mentions an <br />estimate that 90% of the reclaimed land will be <br />flat enough to accommodate mechanized wheel mounted <br />
