estic sources only. The commerical waste is limited to typical restaurant and <br />small business type sewage. No industrial type waste contributors exist in the <br />service area, nor are any expected in the future, due to the resort oriented <br />atmosphere. <br />~t'~ <br />The purpose for stabilizing waste activated secondary treated sludge is to <br />obtain pathogen destruction, volume and weight reduction, odor control and <br />putrescility control. <br />Stabilization of the acquired sludge is accomplished by the aerobic digestion <br />process. The degree of sludge stabilization is monitored and determined on a <br />biweekly basis by laboratory analysis of collected sludge samples. The criteria <br />for ascertaining the stability of sludge as outlined in the State of Colorado <br />Department of Health publication entitled Guidelines for Sludge Utilization <br />on Land will be met prior to the land application of sludge. <br />Current volatile solids reduction is greater than SOY. <br />The stabilized sludge will be transported to the subject site by means of a <br />totally enclosed, watertight truck. The dump body has a tail gate that is also <br />watertight and sealed with a replaceable neophrene gasket. <br />To insure. the consistency of the sludge characteristics, and to verify the <br />effects on surface water, ground water, or vegetation, specific sludge para- <br />meters will be monitored by the producer prior to transport and application. <br />On-site analysis includes biweekly testing of pH, dissolved oxygen, temperature, <br />percent total solids, percent volatile solids, and percent volatile solids <br />reduction. These tests in combination with the extensive testing conducted at <br />the application site will adequately monitor long range effects of sludge ap- <br />plication to land. Analysis of the sewage sludge is presented in Table 1. <br />The sludge treated areas, after revegetation, will be monitored for percent <br />cover, woody plant density and annual production, a minimum of once every three <br />years. A comparison of treated versus control areas will be used to monitor the <br />effects of sludge application as a reclamation enhancement practice at CYCC. A <br />chemical analysis of the overburden, presented in Exhibit 9 of the CYCC Permit <br />79-177, shows that there are no significant problems concerning acid or al- <br />kaline, toxisity forming potential. Water quality parameters to be monitored <br />are; total dissolved salts, total suspended solids, total iron, oil and gcease, <br />pH, and flow. All parameters will be monitored on a weekly basis. Due to the <br />low proposed application rate there are no forseeable problems dealing with the <br />pollution of ground or surface water. <br />t <br />} <br />... .. ~ ~ ..~.4, ~' k <br />
