l• <br />~ . <br /> <br />into and stored in Standley Reservoir. Under certain circumstances the increase <br />may be as much as 540 a.f, per winter season, which is a material increase in the <br />level of pollution. <br />14. The GWTP is owned and operated by the Adolph Coors Company. It <br />treats most of Golden's municipal sewage, as well as sanitary sewage from Coors <br />facilities, and industrial sewage from various Coors facilities including an <br />aluminum can plant, a porcelain plant, and a bottle washing plant. Sewage treated <br />is commingled and discharged to Clear Creek. The quality of the effluent is a <br />function of both Coors' end Golden's contributions. The amount subject to this <br />proceeding is Golden's unsegregated rp o rata share. The sewage receives standard <br />primary and secondary treatment plus partial disinfection by chlorination. <br />Primary wastewater treatment involves sedimentation and removal of solid wastes <br />by settling. Secondary wastewater treatment is a biological process designed to <br />remove oxygen-demanding elements, primarily measured as biochemical oxygen <br />demand ("BOD"). <br />I5. The GWTP discharges wastewater pursuant to NPDES Permit No. CO- <br />00039 (Exhibit BB). The permit was issued by the Water Quality Control Division <br />oY the Colorado Department of Health pursuant to regulations and standards <br />promulgated b9 the Water Quality Control Commission. T1vs program is <br />administered pursuant to the Water Quality Control Act, C.R.S, 525-8-101, et <br />sett. Coors and Golden jointly are the permitees. The permit allows the discharge <br />• of treated sewage that meets 19 effluent limitations ai rates of flow up to 7 <br />million gallows per day (MGD), and would cover the discharges contemplated by <br />Golden's proposed plan. 7 MGD is equivalent to approximately 11 afs.. <br />16. The permit does not assure that the discharge wilt`ttiee of a quality that <br />meets the requirements for which the Objectors' water hen normally-been used. <br />17. The preponderance of the evidence is that municipal sewage contains <br />carcinogens (cancer-causing agents), mutagens (agents causing genetic damage), <br />and pathogens (disease-causing agents) which are not reliably removed by the <br />secondary wastewater treatment plant used by Golden. <br />18. The preponderance of the evidence is that the discharge of the GWTP <br />sewage into a municipal water supply under the proposed terms and conditions will <br />lead to more cases of cancer and other diseases among the population using <br />Standley Reservoir as a drinking water supply. <br />19. The preponderance of the evidence is that, under the proposed terms <br />and conditions, discharge of GWTP effluent into the agricultural water supply, <br />which does not receive any additional treatment prior to use, will lead to <br />additional disease in the men and animals that come into contact with it, and <br />degradation of agricultural and the contamination of crops. <br />20. The preponderance oP the evidence is that this proposal will increase <br />algae growth in Standiey Reservoir. This will result in injurious effects to the <br />• recreational use of the reservoir, and also to the use for drinking water by <br />increasing the cost of treatment. <br />-4- <br />
