However, due to current and anticipated ground conditions, <br />CYCC wishes to delay installation of the replacement flume until <br />late spring or early summer in order to facilitate the required <br />dirt work and compactions associated with the operation. As <br />discussed, CYCC will utilize alternative measurement techniques in <br />order to maintain compliance with the permit during this interim <br />period. <br />Should you have any questions or comments, please contact me at <br />your convenience. <br />Sincerely, <br />i~~~~~~~ " ~~~ <br />Marcus A.
