Process Time The material arriving at the site varies seasonally but will not exceed 500 tons per day, or 156,000 tons per year. The processing time is also feedstock dependent but varies between two and five months. Chemical agents Chemical agents on site are those required in final mixes with finished compost product. Specific agricultural conditions in the area require mixing with additives such as gypsum or lime and these are kept on site to create specialty mixes as required. Final Product The final compost product is sold in bulk to landscape and agricultural use as an organic fertilizer and soil amendment. It may also be sold to nurseries, landscapers, homeowners and municipalities for the same purpose. The demand for this material is high in the area surrounding the facility. Climatic conditions and Inclement Weather Historically, the predominant wind is from the Northwest ranging from 10-20 mph. Maximum wind conditions could reach 30 mph during the month of July. Therefore, careful monitoring of wind conditions is important during the summer months. Windrow turning and moisture content and odor will be evaluated, and operations ceased when winds are over 25 mph and suspended if odor is identified at or near the property line. The area is dry in the summer, with rain averaging 2- 3 inches per month during the winter and early spring. Historically, rainfall totals approximately 15 inches per year. Management practices during the dry months will involve monitoring to be sure enough moisture is in the material, and during the rainy months to prevent any ponding of water on site. The windrows are aligned parallel to the slope of the facility, toward the retention pond to prevent ponding of rainwater on the site. In periods of heavy winds (over 25 mph) site operations will cease to avoid the possibility of fire or dust. If material cannot be incorporated within 72hours, it will be covered with a tarp until. Watering will continue to the site for dust suppression and on the compost piles. Sampling requirements Samples of the composted material will be taken to ensure that metal concentrations and pathogens do not exceed maximum acceptable concentrations by appropriate agencies. They are sent to a laboratory certified by the California Department of Health Services. One sample per 5,000 cubic yards of finished compost product will be analyzed to satisfy this requirement. Compost Sampling Procedures Harvest Power California, LLC operations verify that compost meets the maximum acceptable metal concentration limits specified in Title 14 article 7, section 17868.2, and pathogen
