Upon <br /> completion of the initial application phase subsequent biosolids applications shall be calculated based upon updated soil <br /> and biosolids analyses. Additional organic materials and fertilizer may be applied in combination with the biosolids, <br /> however, the concentration of plant available nitrogen for any such mixture shall not exceed 75 pounds per acre of plant <br /> available nitrogen. <br /> II.B Biosolids Monitoring <br /> Biosolids monitoring requirements are specified in Section 4.9.16.A of the Biosolids Regulation (5 CCR 1002-19, <br /> 4.9.0). Division records indicate that the permittees' 1993 biosolids production rates are as identified below. <br /> Monitoring of biosolids for parameters identified at section 4.9.16, table 7, and to demonstrate compliance with <br /> pathogen destruction criteria identified at section 4.9.12.B(8) and vector attraction reduction criteria at 4.9.12.0 is <br /> required on a once per quarter basis for those facilities exceeding 319 dry tons of biosolids production annually, <br /> and once per year for those facilities which do not exceed 319 dry tons per year biosolids production. The <br /> frequencies of analysis specified above are subject to change should the facilities' biosolids production levels change. <br /> Breckenridge Sanitation District 357 dry tons <br /> Copper Mountain Water and Sanitation District 88 dry tons <br /> Frisco Sanitation District 176 dry tons <br /> Dillon/Silverthorne Joint Authority 255 dry tons <br /> Summit County Snake River Wastewater Treatment Plant 120 dry tons <br /> II.0 Soils Monitoring <br /> Pursuant to Sections 4.9.16.B of the Biosolids Regulation, (5 CCR 1002-19, 4.9.0), post-application soils monitoring <br /> for those parameters identified in 4.9.16.13, tables 8 and 9 of the Biosolids Regulation shall be required. Monitoring <br /> shall be performed on samples collected in accordance with the provisions of section 4.9.16.13 of the Biosolids <br /> Regulation. Samples should be collected so as to be representative of that area to which biosolids are applied within <br /> a given calendar year. It is expected that the amount of acreage to which biosolids are applied will not exceed 320 <br /> acres per year. Thus, for purposes of this section, only a single composite soil sample will be required. Collection <br /> of soil samples is not required until seeding is complete and emergence and establishment of vegetation has occurred, <br /> however, in no case should soil sampling occur more than two years after application has taken place. <br />
