Reference: Cresson Project; Permit Number M-80-244: Statement of File Agreement
Reached on August 29. 1994 Re ag rding Condition of Surface of Soil
Liner.
Dear Mr. Keffelew:
This confirms the agreement reached between your Office (the Office of Mined Land
Reclamation or "OMLR") and Cripple Creek & Victor Gold Mining Company ("CC&V")
regarding the condition of the soil liner surface suitable for overlayment with geosynthetic
material. This agreement was reached in the field during your staff's visit on August 29, 1994.
This also restates [he pertinent information in Allen Sorenson's August 26, 1994 memorandum
to you in a manner satisfactory to both the Office and CC&V.
The approved subgrade for the synthetic liner, which subgrade is derived from the Ironclad
material, is [o be tested to determine the suitability of minus 2" material (tile approved grain size
distribution) in a cylinder test with geomembrane and minus 314 inch material as agreed to on
August 29, 1994. Until that test is successfully completed, the compacted surface of the soil
liner is to be free of large erratic rocks. The procedure to identity and remove such rocks and
to repair the surface was demonstrated and agreed to in the field on August 29, 1994.
In addition, and as always required under the approved plan, the soil liner surface will be free
of visible wood and other non-earthen debris and shall be free of sharp-objects (including rocks)
that protrude in a manner that would, in the view of the quality control and quality assurance
inspectors, pose a problem to liner integrity.
The inspection hierarchy of the liner surface will be (1) the earth movement contractor, (2) the
engineering contractor, (3) the QC inspector, and (4) [he liner installer. Each must be satisfied
with the quantitative and qualitative aspects of the soil liner.
