<br /> <br />COLORADO DEPARTMENT OF HEALTH, Water Quality Control Division <br />Summary of Rationale - Page 13. Permit No. CO-0042439 <br />VII. TERMS AND CONDITIONS: <br />D. Monitoring: <br />3. Sludge Monitoring: <br />a) Sludge disposal: Permittees which practice any methods of <br />sludge disposal, including beneficial use, landfilling, or any <br />combination of disposal methods, are required to perform the <br />analyses shown in Table VII-4. Refer to the permit for <br />locations of sludge sampling points. The results of these <br />analyses and a description of sludge disposal practices are to <br />be included in the annual report. Please see Part I, Section <br />D.3 of the permit for more information. Additional <br />requirements apply if land disposal for beneficial use is <br />practiced. See paragraph (b) following for information. <br />Table VII-4 -- Sludge Monitoring Requirements <br />Sludge Parameter Frequency Sample Type <br />Total Solids, x dry wt. Per Haul Event Grab <br />Volatile Solids, .'~. of total solids Per Haul Event Grab <br />Volume of sludge disposed of, gal/day Per Haul Day Measured <br />Dry weight of sludge disposed, lb/day Per Haul Day Calculated <br />b) Land disposal of sludge for beneficial use: The discharge of <br />solid waste to land for disposal is regulated by the Colorado <br />Solid Wastes Disposal Sites and Facilities Act (30-20, Part 1 <br />CRS 1973). The Act requires that either a Certificate of <br />Designation be issued by the appropriate board of county <br />commissioners for any disposal site located within an <br />unincorporated portion of a county, or that approval be <br />granted by the appropriate governing body of an incorporated <br />portion of a county for any disposal site located within that <br />incorporated area. Sewage sludge Ss considered by definition <br />[30-20-101(6)] to be a solid waste. <br />Section 30-20-102(6) provides an exemption from the <br />Certificate of Designation requirement for sewage sludge which <br />is used in a beneficial manner and is designated as meeting <br />all applicable regulations of the Department including the <br />Colorado Domestic Sewage Sludge Regulations. <br />Requirements of the Domestic Sewage Sludge Regulations are in <br />addition to the monitoring requirements noted in paragraph (a). <br />
