The <br />permanent channel realignment and West Collection channel (also <br />referred to as Diversion Ditch No 1) were submitted on December 17, <br />1990. The designs for the East and West Fill Downdrains and <br />Diversion Ditch #2 are transmitted herewith. <br />This data should accommodate all requests of the Division <br />necessary to meet the July 1, 1991 deadline, except for bonding <br />which is being handled by Oakridge. We plan to revise the drainage <br />over the fill into Sediment Pond #2 in the upcoming second five- <br />year permit renewal. <br />As you know, we have recently obtained revised topography maps <br />which will be useful and necessary to obtain the second five-year <br />permit. We anticipate this package to be a major consolidation of <br />all revisions, modifications with inclusion of current data. <br />Please feel free to call if you have any questions concerning <br />this material or other questions relevant to the Carbon Junction <br />Canyon Mine. <br />Sincerely, <br />PIONEER <br />CORPORATION <br />~ I _ <br />r~ ' \ ` ~~ <br />Darry A.
