<br />~ ,.. <br /> <br />Chapter 2 - Define Water Supply & Water Quality Needs <br /> <br />Sewage Treatment <br /> <br />The Mt. Crested Butte wastewater treatment plant uses an extended aeration <br />variation of an activated sludge process. Treated discharge is released into <br />Woods Creek which flows to Washington Gulch. Sludge from the process is <br />disposed via land application in the summer; The plant experienced seasonal <br />(Christmas) wastewater hydraulic and organic overloading prior to 1995 (see RTW <br />2/23/94 No Action Alternative). <br /> <br />Modifications were made in early 1995 to increase plant capacity to 0.6 MGO. <br />Average peak monthly flows are currently about 0.45 MGD. Improvements <br />include additional flow equalization, aerator, clarifier capacity, UV disinfection, and <br />improved sludge treatment and disposal. Additional sludge treatment and a <br />disposal facility are needed to meet new Environmental Protection Agency (EPA) <br />regulations and a preliminary design report has been written concerning a regional <br />facility with the Town of Crested Butte. RTW has projected average peak <br />monthly flows of 0.723 MGD by the year 2013 and 0.872 MGD by 2033, <br />indicating a need for significant plant enlargement. <br /> <br />Crested Butte Mountain Resort <br /> <br />Water Supply <br /> <br />Mt. Crested Butte Water and Sanitation District meets all of the domestic water <br />supply needs of Crested Butte Mountain Resort (CBMR) with the exception of two <br />restaurant/warming hut facilities located on the ski mountain and water used for <br />snowmaking. The two hut facilities, Paradise and Twister, use chlorinated spring <br />water for their domestic needs. Water is pumped from the East River to meet <br />current snowmaking needs. This system is capable of pumping about 2,200 to <br />2,300 gpm (about 5 cfs or 3.2 MGD) and is used primarily during October through <br />December. Approximately 350 acres of the resort's 612 acres of groomed ski <br />terrain are covered by snowmaking eqUipment. <br /> <br />Crested Butte Mountain Resort is planning a major ski area expansion on Crested <br />Butte North Mountain (Snodgrass Mountain) which lies to the north of the existing <br />ski area development. The snowmaking system planned for North Mountain will <br />serve approximately 200 acres. The pump station on the East River will deliver <br />water to its existing snowmaking operation on Crested Butte Mountain and <br />provide water for the proposed snowmaking system on North Mountain. The <br />pump station is located adjacent to the diversion point for the Mt.
