Kerry Sullivan <br /> November 9, 1993 <br /> Page 4 <br /> be referenced for regulatory. requirements. ' The regulations <br /> include specific design and operating requirements, however, <br /> specific issues related to site size, land use <br /> compatibility, traffic, tonnage, and cumulative impacts <br /> should be addressed in an environmental document. <br /> Aeration of Windrows <br /> Aeration of composting material is required for a number of <br /> reasons, including the prevention of impacts associated with <br /> aerobic conditions . Inadequate frequency; in turning the <br /> windrows would most likely result in anaerobic conditions,` <br /> unless an aerated static pile option was implemented. How Al <br /> will windrows be aerated to prevent them from becoming <br /> anaerobic? How will unfinished compost materials be <br /> adequately aerated to distribute moisture evenly without <br /> clumping of the materials which could; potentially create <br /> anaerobic pockets? <br /> T erature :Conditions to Minimize Pathogens <br /> How will the proposed project maintain temperatures at 53°C <br /> for five consecutive days or 55°C for three consecutive days A2 <br /> to further reduce pathogens? At what temperature is the <br /> compost considered stabilized and suitable for stockpiling? <br /> Co=ost 'Additives <br /> Are additives and amendments . to be used in the composting <br /> process? If additives or amendments are proposed for use in <br /> the composting process, the Composting Regulations under <br /> Article 3, Section 17873 (b) (5) , states that the <br /> 11 . .composting operations shall have leachate holding ' <br /> facilities with a liner with a permeability of no greater <br /> than 1x10'6 cm/sec, and that is constructed of' a thickness <br /> and type ofmaterial that is resistant to damage due to A3 <br /> weather or machinery, . . . " ; and, Section 17873 (b) (4) states <br /> that "Facilities that use amendments :or additives in their <br /> composting operations shall include in their active <br /> composting areas a compost leachate management control <br /> system which is designed to contain and collect twice the <br /> anticipatedvolumeof compost leachate, and the <br /> precipitation from a 25-year/24-hour rainstorm event. <br /> Compost leachate shall be treated if necessary, . . °° . <br />
