met the following environmental health standards for: (1) Maximum acceptable metal concentration, and (2) Pathogen reduction. Sampling. Forward will analyze at least one composite sample for every 5.000 cubic yards of compost. Compost product, which exceeds the maximum metal concentrations or maximum acceptable pathogen concentrations, shall be designated by the appropriate state or federal jurisdiction for another use, including disposal, additional processing, ADCs or other uses. A composite sample will consist of twelve mixed samples. The twelve samples will be of equal volume. Four samples will be extracted from within the compost pile at different cross-sections as follows: • One-half the horizontal width of the pile • One-fourth the horizontal width of the pile • One-eighth the horizontal width of the pile Metal Concentrations. The maximum acceptable metal concentrations are presented in Table 2.3. Tests for meta l.concentration will be conducted at a certified lab: Table 2.3 Maximum Acceptable Metal Concentrations Constituent Concentration (mg/kg) on Dry-Weight Basis Arsenic (As) 41 Cadmium (Cd) 39 Chromium (Cr) 1,200 Copper (Cu) 1,500 Lead (Pb) 300 Mercury (Hg) 17 Nickel (Ni) 420 Selenium (Se) 36 Zinc (Zn) 2,800 Pathogen Reduction. The density of fecal coliform in the stabilized compost will be less than 1,000 most probable number(MPN) per gram of total solids on a dry weight basis, or the density of salmonella bacteria in the stabilized compost will be less than 3 MPN per 4 grams of total solids on a dry weight basis. Compost facilities shall be operated at the minimum temperature and process time requirements presented in Table 2.4.
