ADEQUACY RESPONSE #2
L.G. EVERISTV INC. FIRESTONE GRAVEL RESOURCE -
AUGUST 25, 201 D
estimate based on having most of the existing permit area west
of the old Railroad bed disturbed and partially reclaimed. I
have attached a Bond map showing the area of disturbance.
The Division understands that the excavated "lake" areas will now have a compacted clay liner to satisfy the
SEO requirements and may not, in fact, be filled prior to release. In order to qualify for the 20% bonding option
for a compacted clay liner, the operator will need to provide design specifications for the liner that satisfy, at a
minimum, the requirements of the clay backfill pit liners portion of the "Guide to Specification Preparation for
Slurry Wall and Clay Liners as a Component of a Colorado Mined Land Reclamation Permit" document dated
September 2000 and available on the DRMS web site.
Attached is a copy of. the PROJECT MANUAL FIRESTONE GRAVEL RESOURCE
SLOPE LINER containing the design specifications for the
proposed liner. This document was prepared by Deere & Ault
Consultants, Inc. to meet the requirements outlined in the
"Guide to Specification Preparation for S1-urry Wall and Clay
Liners as a Component of a Colorado.Mined Land Reclamation
Permit". With the approval of these design specifications,
the 20% bonding option will apply.
Please also provide the linear feet of compacted clay liner that will be required for each excavated ("lake") area.
This will allow a much easier calculation of the bond required for each phase of the operation as well as
facilitate bond releases when any individual lined phase passes SEO testing.
LAKE LINER AVERAGE FILL PER
AREA LENGTH (FT) LINEAR FOOT. (.YDS)
PHASE 2 5,090 60.0
PHASE 3 12,245 53.5
PHASE 5 16,865 40.5
Exhibit S - Permanent Man-made Structures (Rule 6.4.19)
The Division has received proof that the operator has pursued agreements with all structure owners within 200'.
If additional agreements are executed by structure owners in the future, please forward copies to the Division for
inclusion in the site record.
Thank you, we will keep the file up to date if/when additional
agreements become available.
Although not specifically required, it would likely be in the best interest of LG Everist to renew old agreements
with existing structure owners that have been carried forward from the previous permittees (EnCana, Last Chance
Ditch).
Discussions are underway with all the oil companies and the
ditch company to get updated agreements for the site. Once
available, they will be submitted to the Division for the
record.
