Historically, the predominant wind is from the Northwest ranging from 10-20 mph. Maximum <br />wind conditions could reach 30 mph during the month of July. Therefore, careful monitoring of <br />wind conditions is important during the summer months. Windrow turning and moisture <br />content and odor will be evaluated, and operations ceased when winds are over 25 mph and <br />suspended if odor is identified at the near the property line. <br />The area is dry in the summer, with rain averaging 2- 3 inches per month during the winter and <br />early spring. Historically, rainfall totals approximately 15 inches per year. Management <br />practices during the dry months will involve monitoring to be sure enough moisture is in the <br />material, and during the rainy months to prevent any ponding of water on site. The windrows <br />are aligned parallel to the slope of the facility, toward the retention pond to prevent ponding of <br />rainwater on the site. <br />In periods of heavy winds (over 25 mph) site operations will cease to avoid the possibility of fire <br />or dust. If material cannot be incorporated within 36 hours, it will be covered with a tarp until. <br />Watering will continue to the site for dust suppression and on the compost piles. <br />Sampling requirements <br />Samples of the composted material will be taken to ensure that metal concentrations and <br />pathogens do not exceed maximum acceptable concentrations by appropriate agencies. They <br />are sent to a laboratory certified by the California Department of Health Services. One sample <br />per 5,000 cubic yards of compost will be analyzed to satisfy this requirement. <br />Compost Sampling Procedures <br />Harvest Power California, LLC operations verify that compost meets the maximum acceptable <br />metal concentration limits specified in Title 14 article 7, section 17868.2, and pathogen <br />reduction requirement, specified in Title 14, Article 7, Section 17868.3, shall occur at the point <br />where compost is sold and removed from the site, bagged for sale, given away for beneficial <br />use and removed from the site or otherwise beneficially used. This verification shall be <br />performed by taking and analyzing at least one composite sample of compost for every 5,000 <br />cubic -yards of compost produced. The composite sample shall be representative and random, <br />and may be obtained by taking (12) mixed samples as described below. <br />-The twelve samples shall be of equal volume. <br />-The twelve samples shall be extracted from within the compost piles as follows. <br />-Four samples from one-half the width of the pile, each at different <br />cross-section; <br />-Four samples from one-fourth the width of the pile, each at different cross- <br />section; <br />-Four samples from one-eighth the width of the pile, each at different cross- <br />section; <br />-Using a sanitized sampling tool, while also wearing plastic gloves, collect the samples <br />required and transfer them to the sampling container, previously prepared. <br />-All 12 samples are mixed together. <br />7 <br />
