'' <br />Mr. Donald H. Simpson <br />January 9, 1985 <br />Page Two <br />The plan for handling the discharge from the spring is to divert the wa- <br />ter around Pond F without contacting disturbed lands. The layout of the pro- <br />posed diversion is shown on the attached figure. A berm will be built around <br />the spring location, with an intake built into the berm. A 24-inch pipe will <br />be installed to carry the water to a culvert, where the discharge will be <br />directed to the receiving stream of Foidel Creek. The pipe is designed to <br />carry the maximum flow rate from the spring, and will be buried below the <br />frost line to prevent freezing. <br />CYCC is responding to the interpretation of Part II.A.1 of the permit. <br />The permit allows discharge from the mine facility in compliance with appli- <br />cable effluent limitations on water quantity and quality. The discharge from <br />the spring has not caused excursions from these effluent limitations to occur, <br />and the rate of discharge has not exceeded the design rates for which Pond F <br />was constructed. CYCC is requesting approval of the diversion as a precau- <br />tionary measure, and proposes to install the diversion prior to the runoff <br />season in 1985. <br />Please send any correspondence on this subject to me to the above letter- <br />head address. <br />Sincerely, <br />1'~r~ ...) .• , <br />Richard Hughes <br />Environmental Specialist <br />RH/kk <br />cc: K.
