The geotechnical analysis completed by CTL/Thompson, Inc.,
• concluded that the Streeter Fill, as built by Colowyo meets the
stability requirements of OSM regulations.
The fill did not, however, meet the design criteria requirement of
the OSM Interim Regulations and therefore was still in violation.
To resolve the issue, OSM agreed to withdraw the Notice of
Violation conditioned upon the agreement that Colowyo submit an
application for qualifying the Streeter Fill under the Experimental
Practices Program referred to in 30CFR, Section 785.13; see Hearing
for Review of Notice of Violation No..79-V-1-4, August 7, 1979 in
Exhibit 12, Experimental Practice Information.
Subsequent to the hearing, Colowyo filed an application for an
experimental practice on September 4, 1979, (see Exhibit 12,
Experimental Practice Information) and receipt of the application
was acknowledged in a letter from Walter N. Heine, Director of OSM,
on September 28, 1979 (see Exhibit 12, Experimental Practice
Information).
To date, there have been no final approvals or denials of the
• Experimental Application by OSM or the Division.
In correspondence dated October 11, 1979, OSM requested the
Division recommend approval of the experimental practice
designation for Colowyo's Streeter Fill. In a letter dated
February 13, 1980 the Division replied to OSM that approval of the
experimental practice could not be given until certain questions
were resolved. A copy of the correspondence from the Division, the
February 6, 1980 letter from Mr. Jim Pendleton commenting on the
Slope Stability Analysis of Colowyo's Streeter Fill, and the
February 13, 1980 letter from Mr. Fred Banta to Mr. Donald Crane
requesting Clarification Before Approval of Colowyo's Streeter Fill
is included in Exhibit 12, Experimental Practice Information. On
March 24, 1980, CTL/Thompson, Inc. responded to the concerns of the
Division (see Exhibit 12, Experimental Practice Information, March
24, 1980, letter from CTL/Thompson, inc. to OSM commenting on
Questions Raised by Division Concerning Colowyo's Streeter Fill).
