DEALING WITH EXISTING SURFACE FACILITY CONFIGURATIONS AND WITH THE PROPOSED
ALTERNATIVE SITES AND STRUCTURES FOR A COAL PROCESSING WASTE PILE.
THIS ANALYSIS SHALL BE COMPLETED AND A REPORT SUMMARIZING THE RESULTS
AND METHODOLOGY THEREOF SUBMITTED TO THE DIVISION FOR REVIEW BY DECEMBER
31, 1981.
COLORADO WESTMORELAND, INC. IS DIRECTED TO COMPLETE PHASE III OF THE
STABILITY ANALYSIS AND REDESIGN OF THE FINAL RECLAIMED CONFIGURATION
OF THE SURFACE FACILITIES OF THE ORCHARD VALLEY MINE, AS DESCRIBED
IN THE VARIOUS LETTERS OF PROPOSAL FROM MERRICK & COMPANY AND GEOHYDRO
CONSULTANTS INCLUDED IN VOLUME 10 OF THE AMENDED APPLICATION. THE
SCOPE OF PHASE III SHALL INCLUDE THE UTILIZATION OF THE FINDINGS AND
RECOMMENDATIONS OF PHASE II TO COMPLETE FINAL DESIGN OF THE PROPOSED
COAL PROCESSING WASTE PILE AT THE ORCHARD VALLEY MINE. THIS PROJECT
SHALL PROCEED IN A TIMELY FASHION TO COMPLETION BY JUNE 30, 1982. THE
DIVISION SHALL BE KEPT INFORMED BY MONTHLY LETTER OF THE PROGRESS OF
THIS TASK BY THE OPERATOR. UPON FINALIZATION OF THE COAL PROCESSING
WASTE PILE DESIGN, THE ORCHARD VALLEY MINE PLAN SHALL BE APPROPRIATELY
AMENDED.
In the interim, prior to final approval of an acceptable coal processing waste
disposal site and structure, waste will continue to be generated at the Orchard
Valley mine and must be disposed of in an acceptable manner. In order to
prevent the accumulation of a large amount of waste in an unacceptable site
and structure, the Division imposes the following stipulation upon the permit:
COLORADO WESTMORELAND, INC. IS DIRECTED TO FINALIZE THE DESIGN OF
THE PROPOSED COAL PROCESSING WASTE STRUCTURE AT THE ORCHARD VALLEY
MINE. THIS DESIGN IS TO BE COMPLETED BY JUNE 30, 1982. PRIOR TO
APPROPRIATE AMENDMENT OF THE MINE PLAN, THE OPERATOR MAY CONTINUE
PLACEMENT OF COAL PROCESSING WASTE AT THE EXISTING WASTE PILE LOCATION.
HOWEVER, WASTE PLACEMENT MUST CONFORM WITH THE REQUIREMENTS OF RULE
4.10.4(3) , AND THE TOTAL AMOUNT OF COAL PROCESSING WASTE PLACED IN
THE EXISTING SITE SHALL NOT EXCEED 25,000 YARDS, INCLUDING WASTE NOW
DEPOSITED AT THAT SITE. IN THE EVENT THAT THE TOTAL QUANTITY OF WASTE
DISPOSED OF AT THE EXISTING SITE EXCEEDS 20,000 YARDS3, THE OPERATOR
SHALL INFORM THE DIVISION IMMEDIATELY. IF TOTAL WASTE PLACEMENT IS
ANTICIPATED TO EXCEED 25,000 YARDS3 AT THE EXISTING SITE, THE OPERATOR_
SHALL COMPLETE A STABILITY ANALYSIS OF THE EXISTING COAL PROCESSING
WASTE SITE AND STRUCTURE TO ASCERTAIN ITS CONFORMANCE WITH THE
REGULATIONS OF RULE 4.10. IF THE TOTAL QUANTITY OF COAL PROCESSING
WASTE EXCEEDS.25,000 YARDS3 AT THE EXISTING DISPOSAL SITE, THAT
STRUCTURE SHALL BE BROUGHT INTO CONFORMANCE WITH THE PERFORMANCE
STANDARDS OF RULE 4.10 WITHIN 6 MONTHS THEREAFTER. FURTHERMORE,
IN ADDITION TO THE INSPECTION AND REPORTING REQUIREMENTS OF RULE 4.10.2,
CWI SHALL SUBMIT RECORDS OR CALCULATIONS TO VERIFY THE TOTAL ACCUMU-
LATED QUANTITY OF COAL PROCESSING WASTE DISPOSED OF AT THE EXISTING
SITE AS A PORTION OF ITS QUARTERLY INSPECTION REPORT TO BE SUBMITTED
TO THE DIVISION.
