The facility will not accept or process mixed municipal solid waste from any source. Each batch of incoming waste will be mixed together in various percentages to maximize the composting process, sewage sludge is added in percentages anywhere from 10% to 50% for moisture conditioning and to add needed nitrogen to the compos~ material. Incoming material will be processed to the correct size (if necessary) and will then be mixed according to appropriate infeed ratios suitable for composting. There will be a maximum storage Capacity of 24 hours for incoming material. Raw materials will be mechanically mixed in a stationary mixer located inside the building and loaded into the compost bays with a skid steer type loader. Wood waste and yard waste (es. leaves and brush) will be stored outdoors on the paved storage area on the north side of the building. Brush and wood waste will be chipped and stockpiled on a monthly basis during peak seasons.
