June 11, 1992 - Colowyo submits page 4.05-2A requested by S. Wathen, MLRD, which explains joint modelling effort and intent to complete effort no later than August 31, 1992. June 15 - August 19, 1992 - Colowyo constructs the Prospect Pond and entire South Collection Ditch. June 30, 1992 - MLRD approves Colowyo's Permit Application. August 14, 1992 - J. Garcia meets with S. Wathen for the fast time, to discuss new hydrological modelling requirements. S. Wathen dismissed all previous hydrological modelling and justifications submitted by Colowyo as • inadequate. Asked to justify the basis for this decision, he stated that he was the regulator, and that it was his opinion, and that it was too bad if Colowyo disagreed. September 29 - October 1, 1992 - DMG/OSM oversight inspection at Colowyo. L. Routten and S. Wathen, DMG, and G. Fritz, OSM, inspected both the Prospect Pond and South Collection Ditch finding both to be in compliance with the regulations. October 21, 1992 - Meeting in Denver to discuss Prospect watershed hydrological modelling. Completely new model developed. October 29, 1992 - Colowyo requests additional time extension to resolve modelling differences with a projected resolution date of December 31, 1992. December 1, 1992 - DMG agrees to additional time extension to resolve modelling differences. DMG also requests as-builts for the prospect Pond and South Collection Ditch to be submitted by December 11, 1992. December 10,1992 -Letter written to S. Wathen, DMG, stating that as per telephone conversation agreement with J. Garcia, as-builts certification and maps for the prospect Pond and South Collection Ditch plus the Prospect Pond Hydrologic Modelling SEDCAD runs would be hand delivered to S. Wathen at the Colowyo minesite on December 14, 1992. December 14,1992 -The above mentioned certifications and hydrologic modelling were hand delivered to S. Wathen. The hydrologic modelling was in the form of a computer disk which was to aid S. Wathen in a timely review of the modelling run, developed by J. Garcia from the basis developed jointly on October 21, 1992. Modelling entailed a complete new model development and computer runs of the Prospect watershed. Final results showed that the required sizing for the Prospect Pond under this new modelling requirement was 0.72 ac.ft. capacity. Colowyo's May 10, 1992 design capacity was 6.5 ac. ft. with the actual as-built size being 7.75 ac.ft.
