SECTION 5 -COMPOSTING AREA • A product sales area located near the finished product storage area. Up to three surface water retention ponds to capture runoff from the active operating areas. The site will be graded to separate runoff from the ASP and receiving area from the rest of the site so that surface water collected from areas other than the ASP pad and receiving area can be used to moisten piles as needed. Leachate and condensate that collect within the aeration system's laterals and ducts will be captured and drained via gravity through polyvinyl chloride piping to one of two leachate manholes. The two leachate manholes will also serve as the "water trap" that is necessary to allow leachate and condensate to drain continuously from the aeration system while it is in operation. The leachate manholes will be equipped with electric pumps and float level sensors that will transfer liquid that collects in the manhole to the retention pond located near the ASP area. 5.2 Facility Capacity The facility is designed to accept and process the projected 7,000 tons per year of feedstocks that are anticipated. The facility design also factors in the historical peaking factor based on quarterly data from 2013 through 2015 from the existing site. However, the mass of material present at the site at any one time will vary based on the type of equipment used to form and turn the windrows, residence times, and the density and moisture content of the materials being composted. For these reasons, it is more convenient to refer to the volumetric capacity of the various composting systems. The facility will have the following capacities: • The ASP composting system is designed around operators constructing two composting piles per week which have a combined capacity of up to 654 cubic yards (yd 3). At times of the year when feedstock quantities are lower, the composting piles will be built with a lower height. • The capacity of the windrow composting and curing operation is expected to be approximately 5,028 yd3. However, this capacity may change (increase or decrease) as a result of changes in turning methods and equipment and changes in windrow spacing. These changes can be accommodated without the need to expand the physical size of the windrow pad. The amount of material stored in the finished product storage area is expected to vary significantly from year to year. Also, amounts will vary within each year based on compost production levels and market demand. The capacity of the area will be based on storage of materials in eight rectangular piles (75 feet by 55 feet). However, this storage capacity will be increased to respond to lagging seasonal or year -over -year market demands by building stockpiles closer together or using an extended pile configuration. 5.3 Acceptable Feedstocks The new facility will be designed to process the same materials that the existing facility is permitted to receive and process (Type 1 [vegetative] and Type 2 [manures] feedstocks), which include the following: • Landscaping and yard trimmings • Wood wastes (natural woody debris, including land clearing stumps and brush, and clean, unpainted, and untreated dimensional wood) • Straw and bedding with associated manures (primarily from nearby fairgrounds and small farms) Future addition of pre -consumer food waste may be considered at a later date. The current site experiences seasonal variation of compost material depending on the weather. During the late fall and early winter periods, incoming material contains a higher proportion of brush and tree limbs. 5.2 EN1213161143SAC DRAFr- 12/23/16
