RE: Reservoir Liner, Connell Resources, Inc., Wellington Downs Pit,
File No. M-95-035
In the applicants adequacy response dated 8/3/95, it is stated that the
frequency of compaction testing for installation of the proposed clay
liner should be regulated by the State Engineer's Office (SEO). This
response is not acceptable under section 34-32-116(2) C.R.S. If the SEO
does specify testing frequencies different than those committed to in a
Reclamation Permit, then the operator would obviously be required to
comply with whichever frequency is more stringent, or could propose a
frequency that would satisfy both agencies.
I would recommend that the operator be required to complete the following
materials testing at the specified frequencies during installation of the
reservoir liner:
Type of test Frequency of testing Material
in c.y placed specification
Sieve test 5000 90-100$ passing 3/4"
15-50$ passing X200
Atterberg limits 5000 > 10 p.i.
Compaction 5000
Moisture/Density 1000 w/in 3$ optimum
moisture; > 95$ Max.
dry density
The operator would be required to provide test results demonstrating
compliance with these specifications upon completion of any single phase
of reservoir liner installation.
