from the green waste material after it has been shredded. Since incoming <br /> biosolids are not anticipated to have heavy metal concentrations above regulatory <br /> limits, other preprocessing procedures will not be necessary. <br /> d. Process Time <br /> Estimate the average process time to convert waste materials to compost including <br /> volume of compost to be shipped out (daily, weekly, or monthly). <br /> Describe the maximum and average length of time green material will be stored at the <br /> facility. <br /> As discussed in Section 1.3.1 - Maximum Daily Load Capacity, the Compost Facility <br /> is designed and permitted to process up to 1,100 TPD of waste. The specific <br /> capacity depends on the composting process being used, density of materials, and <br /> the quality of compost product. The compost process time is projected to be <br /> between approximately 4 to 12 weeks, depending on the compost product quality. <br /> The curing process will take from approximately 1 to 6 months. <br /> e. Chemical or Bulking Agents <br /> List any chemical additives or building agents and the estimated amount to be used for <br /> finishing the composting process. Describe the application method. <br /> Chipped green waste or screened oversize materials will be used as bulking <br /> agents, as necessary. <br /> 3.5.3 Climatic Conditions <br /> If climatic conditions such as frost, snow or wet weather are likely to adversely affect site <br /> access or the operation of aerating Windrows or static piles, outline measures to <br /> overcome these effects. <br /> Climatic conditions are not expected to adversely affect site operations. It does not snow <br /> or freeze at the site. Forward implements a winterization program each year to install all <br /> weather roads for access. <br /> The climate of the region is typical of the California Central Valley. Winters are <br /> generally cold and wet with fog, while summers are hot and dry. <br /> Climatological data used in the site design was gathered from representative weather <br /> stations near the site. Representative climatologic stations were selected based on their <br /> proximity to the site and reliable period of records for the station (30 years or more). <br /> Temperature. Normal monthly temperatures were calculated from the Stockton Weather <br /> Station office (WSO) (No. 8558, latitude 37054', longitude 121015', Elevation 22 msl), <br /> located approximately 3 miles west of the site, from data collected from 1948 through <br /> 1990. These temperatures ranged from a minimum average value of 42.5°F in January <br /> to a maximum average value of 78.0°F in August, with an annual mean <br /> temperature of 61.5°F (National Climatic Data Center, 1990). <br /> Precipitation. Precipitation at the project site is typical of the Central Valley region. <br /> Rainfall is seasonal, with approximately 90 percent of the rainfall occurring <br /> between November and April. Snowfall is unusual at the site. <br /> Forward Composting Facility RCSI <br /> 7/20/09;Page 39 SWT Engineering <br />
