Mid-Term Review 14 November 27, 1985
Stipulation No. 8
PRIOR TO THE DEVELOPMENT OF MAINS AND SUB-MAINS BENEATH THE ALLUVIAL BODY OF
RED WASH, THE APPLICANT MUST SUBMIT THE INFORMATION REQUIRED BY SECTION 2.06.8
(4) OF THE COLORADO REGULATORY PROGRAM, ALONG WITH A PLAN TO ENSURE THAT THE
PERFORMANCE STANDARDS AND MONITORING REQUIREMENTS OF SECTION 4.24 ARE MET.
THIS PLAN MUST ADDRESS THE ANALYSIS OF SUBSIDENCE MONITORING DATA COLLECTED TO
DATE. MINING BENEATH THE ALLUVIUM OF RED WASH SHALL NOT COMMENCE UNTIL THE
SUBMITTALS ARE APPROVED BY THE REGULATORY AUTHORITY. IT IS ALSO RECOMMENDED
THAT THE APPLICANT MEET IN ADVANCE WITH HE REGULATORY AUTHORITY REGARDING THE
PLANNING OF THE STUDIES REQUIRED BY SECTION 2.06.8(4).
The Division received a copy of the "Red Wash Drainage Basin Alluvial Valley
Floor Study" for the Deserado Mine on July 27, 1983. Based on a review of
this information, the Division made a negative AVF Determination for the Red
Wash Alluvial body and revised the findings document accordingly during
October of 1983. However, Western Fuels must submit an analysis of subsidence
monitoring data prior to mining beneath the alluvium of Red Wash.
Stipulation No. 9
THE APPLICANT MUST ALSO SUBMIT, AS PART OF THE PERMIT APPLICATION, WRITTEN
DOCUMENTATION AS TO THE NATURE OF THE REGIONAL IRRIGATION INVENTORY
PERFORMED. THIS DOCUMENTATION MUST ADDRESS THE DEFICIENCIES OUTLINED IN
SECTION C OF THIS TEA, SO THAT THE AVF DETERMINATION FOR SCULLION GULCH CAN BE
ADEQUATELY SUBSTANTIATED. THE INFORMATION SHOULD BE SUBMITTED WITHIN 30 DAYS
OF THE GRANTING OF THE PERMIT.
A letter indicating that this stipulation had been resolved was forwarded to
the Division on June 24, 1981 (letter dated June 22, 1981). Upon review of
the Deserado findings document,it appears that the actual documentation was to
take the form of a letter from Mr. Alvin Jones of the SCS -Meeker area office
to the Division which documents local irrigation conditions. A detailed
review of the OSM findings document (page 10, AVF section) reveals, however
that sufficient documentation was already in existence in the form of a
published SCS report entitled "Important Farmland Inventory - Colorado" dated
September, 1980 which includes maps of Rio Blanco County. As such,
Stipulation No. 9 is considered resolved. The requested written documentation
from Mr. Alvin Jones was received by the Division and is contained within the
Deserado Mine file.
Stipulation No. 10
THE APPLICANT SHALL PROVIDE THE REGULATORY AUTHORITY WITH A CORRECTED VERSION
OF MAP 77, REFUSE DISPOSAL AREA SITE PREPARATION WHICH SHOWS THE LOCATION OF
THE CULVERT THAT CARRIES FLOW FROM THE NON-TOXIC FILL STOCKPILE DITCH ACROSS
THE HAUL ROAD INTO THE SUBAREA RP2-3 SEDIMENT POND. THIS INFORMATION SHOULD
BE SUBMITTED WITHIN 90 DAYS OF APPROVAL OF THE MINE PLAN PERMIT.
A corrected version of Map 77, (2 copies of Revision 1 of the map) was
submitted to the Division on October 23, 1981. Stipulation No. 10 is
therefore considered resolved.
