Table 2.4 0 Minimum Temperature and Process Time Requirements for Pathogen Reduction Facility Minimum Minimum Temperature(°C) Duration (Days) Enclosed or within-vessel 55 3 Windrows 55 15 Aerated Static Pile 55 3 1Must maintain aerobic conditions and be turned at least five times. ZA 6-to 12-inch cover is required. Daily temperature measurements shall be measured for pathogen reduction as follows: • Windrow composting processes and agitated bays shall be monitored twelve (12) inches below the pile surface • Aerated static pile composting processes shall be monitored twelve to eighteen inches below the insulation cover The temperature reading will be taken per 150 feet of Windrow, or faction thereof, or for every 200 cubic yards of active compost. iosolis. If biosolids are composted, monitoring for metals, pathogen density, and active compost temperatures will be performed at the frequency listed in the Table 2.5. Table 2.5 Frequency of Compost Product Monitoring Amount of Biosolids Compost Feedstock(metric Frequency tons per 365-day period) Greater than zero but fewer than 290 Annually Equal to or greater than 290 but fewer than 1,500 Quarterly Equal to or greater than 1,500 but fewer than Bimonthly 15,000 Equal to or greater than 15,000 1 Monthly To meet the requirements of Sections 17868.2 and 17868.3 (see 17868.1 (a)(1)), at least one composite sample shall be analyzed for every 5,000 cubic yards of compost produced. Green Materials. If more than 5,000 cubic yards of green materials and agricultural plant materials are in the feedstock or active compost at any one time, the final product will be analyzed for maximum metal concentrations and pesticide residues, according to U.S. EPA methodology 8270.
