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 36 hours, 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 reduction requirements specified in Title 14 Article 7 Section 17868.3 shall occur at the point where compost is sold and removed from the site bagged for sale, given away for beneficial use and removed from the site or otherwise beneficially used. This verification shall be performed by taking and analyzing at least one composite sample of compost for every 5,000 cubic -yards of compost produced The composite sample shall be representative and random and may be obtained by taking twelve (12) mixed samples as described below. • The twelve samples shall be of equal volume. • The twelve samples shall be extracted from within the compost pile as follows. - Four samples from one-half the width of the pile, each at different cross- section: - Four samples from one-fourth the width of the pile, each at different cross- section:
