9. Surface water disturbance. Paragraph (i) states groundwater will not be encountered, but does
not discuss surface water. Based on the reclamation plan map in Exhibit E, the grade of the
pit floor is towards the south at a 1% grade,towards the irrigation ditch/canal. Please describe
how the ditch/canal will be protected from eroded sediment during operations and post closure,
prior to the re-establishment of vegetation.
6.3.4 EXHIBIT D—Reclamation Plan
10. Site revegetation. Paragraph (c) on p. 3 of the Reclamation Plan references the "reclamation
plans to be utilized on the Lemay Realignment' and was not included in the submittal, which
may or may not address the missing information required by Rule 6.3.4(1)(c). Please specify
the following information:
a) State the thickness of plant growth medium to be replaced.
b) Explain how the seedbed will be prepared to eliminate compacted conditions (e.g.,
plowed, chiseled, disced).
c) State the grass, forb, shrub and tree species to be planted and the applicable quantities.
Specify the quantity of each grass and forb species as pounds of pure live seed per acre.
d) Specify the application method for grass and forb seeding. (Note: if the seed is to be
broadcast, the application rate shall be twice the rate required for seed drilling).
e) If mulch is needed, specify the kind to be used, the crimping method, and rate of
application.
11. Cost Estimate. Rule 6.3.4(2) requires applications provide an estimate of the actual costs to
reclaim the site based on what it would cost the State of Colorado using an independent
contractor to complete reclamation. The exhibit indicates the use of a Cat 623 scraper and a
D6 dozer, as well as suggesting seedbed preparation, application of soil amendments, seed and
mulch; yet only proposes mobilizing two pieces of equipment. This rule also specifies
including indirect costs. Please provide information on the type of equipment planned for
seedbed preparation, and the application of seed, mulch and soil amendments. (Note: the
reclamation cost estimated by the DRMS will include indirect costs.)
12. CDI quote. Section 2 on p. 3 of Exhibit D indicates the CDI reclamation is for 8.0 acres. The
application form states the permit area is 8.7 acres and based on your response to Comments 7
and 8 above, may be much closer to 9 acres. Please explain why only 8 acres are costed for
re-seeding in Section 2.
13. Dryland Pasture Mix. The "Buffalo Brand Seed" mix provided is vague in that it does not
specify pounds of pure live seed or indicate a specific seed rate or application method as
discussed in Comment 1 Oc and d above.
6.3.5 EXHIBIT E—Map
14. Map requirements. Rule 6.2.1(2) requires maps must be prepared and signed by a registered
land surveyor, professional engineer, or other qualified person; and give the date prepared.
The two maps submitted in Exhibit E are not signed and the date is too small to read. The
resubmitted maps must be signed by the engineer, surveyor or other qualified person that
prepared them and the date must be legible.
15. Map information. Exhibit E maps must include the following:
