Parameter - Unit Method <br /> Moisture ~ EPA 160.3 <br /> <br /> Total Nitrogen ~ dry weight EPA 351 and <br /> 353 <br /> <br /> Total Phosphorus ~ dry weight EPA 365 <br /> Total Potassium % dry weight EPA 3050/7610 <br /> <br /> Reduction in <br /> Organic Matter ~ EPA 160.4 <br /> <br /> Organic Matter ~ EPA 160.4 <br /> pH standard units EPA 9045 <br /> <br /> The reduction of organic matter shall be determined by <br /> comparing the organic matter content of the feedstock into the <br /> composting process and the organic matter content of the <br /> compost product by measuring the volatile solids content using <br /> EPA method 160.4. The amount of reduction shall be determined <br /> as a percent of the original amount contained in the feedstock <br /> using the following calculation: <br /> <br /> %ROM = [1 - (OMK - )M) / OM(100 - OMK))]IO0 <br /> <br /> where: ~ROM = reduction of organic matter, OM = ~ organic <br /> matter content of dry matter before decomposition, and OMK = ~ <br /> organic matter content of dry matter after decomposition. <br /> <br /> History Note: Statutory Authority G.

The directions shall address maturity, moisture holding <br />capacity, and nutrient content. <br /> <br />History Note: Statutory Authority G. S. 130A-309.11~ Elf.
