2.4 Location of OSCR Vermicul ture Bins
Yes No
o n The bins will be placed near the source of waste being processed.
o n The bins will be located in the same area as the existing waste disposal containers.
o o The bins will be placed within reach of a garden hose.
o The bins will be equipped with nursery type heat cable. Elechic power is required and is available at the location.
o o A qualified elechician will determine the power requirements and will provide adequate sewice at the location.
o o The bins will be painted white or a light reflecting color to reduce heat absorption from sunlight.
o o The bins will be placed inside another structure to reduce exposure to temperature extremes.
o o Locking hasps on top and front access doors will be used to deter vandalism.
2.5 Identification of organic waste stream
Yes No
o o There is an adequate balanced supply of organic waste generated at this site.
o o There is not an adequate balanced supply of organic waste generated at this site,therefore, we will apply for a solid waste handling permit to accept waste from other sources with the annual tonnage equal to the processing capacity of the number of bins at this site.
o o Kitchen preparation area vegetative food and paper waste
o o Dinning Area sewing tray scraps.
o o Classroom and office paper waste.
o o Yard Waste.
o o The oil and grease from the kitchen are specifically excluded from the waste fed to the OSCR bins but the quantity of oil and grease on the students plates is not great enough to be a concern. However, this practice will be reviewed in light of actual experience.
o o Since microbes multiply rapidly on meat waste, food waste with meat scraps will be added to the bins in smaller quantities so the red worms can process it quickly. This will reduce formation of odors, flies and potential anaerobic conditions, which are toxic to red worms.

2.6 Separation of organic waste stream
Yes No
o o Containers will be provided in the kitchen area for collection of appropriate food waste.
o o Containers will be provided in the dining area for collection of appropriate food waste.
2.7 Control of liquids entering OSCR Vermiculture Bins
Yes No
o o The closed vessel design prevents excess water in the form of rain or snow ftom entering the system.
o o Liquids will be sepamted 6om targeted wastes in the kitchenldiniig area and poured down a drain connected to a waste water treatment facility.
2.8 Measurement of balanced CarbodNitrogen ratio
Yes No
o o A waste stream will be identified and targeted which will provide a relatively consistent mix of Carbon:Nihogen in the range of 25-40 parts carbon to one patt nitrogen.
o o This site will target six pounds of food waste per day, one and a half pounds of paper w wood chips will be target4 and this will require one OSCR vermiculture b i i
o o This site will target 42 pounds of food waste per day for five days of each week. The food waste will be covered with 10.5 pounds of paper or wood chips each day. This will require five OSCR vermiculture bins to balance the processing rate and the C.N ratio.
o o All OSCR bins will be fed daily.

2.9 Educational Activities:
Yes No
o o The vermiculture system operated at this site will be used for educational purposes. Efforts will be made to provide learning experiences for the people involved in the daily process and efforts will be made to share the experience with the community.
o The vermiculhue system operated at this site will be used only as a waste reduction and recycling tool.
2.10 Health Concerns:
Control of scavenger animals and nuisance insects
Yes No
o n The design of the bin provides sufficient means for restricting access to the food waste.
o The bin@) will be placed within a fenced or enclosed area
o The design of the bin pmvides means for restricting access to the food waste by undesirable insects through the use of tight fitting doors and screened air vents.
n n The use of paper or wood chips for "Daily Cover" will be used to further restrict access by undesirable insects.
Control of odors
Yes No
n o The design of the OSCR bin is an adequate measure to control nuisance odors.
Ammonia Odor
o o When ammonia odor, is present, high &n materials will be added to the bin. The bin will also be given extra water to help flush the ammonia h m the system.
Rotting Odor
o Primary action, break up compacted or wet material with hand tool to provide air channels.
o o Secondary action, remove pockets of rotting anaerobic material if there is no sign of worm activity in the area and dispose of it in bash container.
o o Long tenn action, stop or reduce the volume of food added to the bin until condition is corrected.
Appendix A-4
OSCR Vermiculture Compost System
Control of leachate from vermiculture bins
Yes No
o o The captured liquid is a "nutrient tea" and can be strained, bottled and used in a diluted form as plant or lawn food. This method requires some experimentation and analysis.
o o The captured liquid can be added in small quantities to the water used to moisten the paper and wood fiber in the daily cover.
o o During part of the year, evaporation will take care of the leachate, but during wet or freezing weather excess liquids may build up faster than the system is designed to capture. The tea can be poured off into plastic 5 gallon buckets and sealed until weather conditions are such that evaporation will reduce the volume or the liquid can be used as described above.
o o Captured liquids will be poured down a draii connected to a waste water treatment facility.
Health concern with students and staff handling waste
Yes No
o o Students and staff will wear disposable plastic gloves when handling the waste or the worms. Thomugh washing of hands afterward is required.
o o Waste paper 6om the wash basin areas will not be allowed into the feed of the vermiculture system.
o Operators will be informed of the health and safety issues for handling waste and castings.
Out of Balance Systems
o Students will be allowed to volunteer for cleanup operations. mi can be a valuable lesson)
o The maintenance personnel agree to or have been d i e d to assume overall responsibility for major cleanup operations.
o in the event of a totally failed system the maintenance staff will remove the contents of the bins to proper waste disposal containers and clean the area
Appendix A-5

Summer vacation feeding a n d maintenance program fo r schools
Yes No
n o Allow the bins to go dormant, no food or water, for the summer break period.
o o Harvest and sell or give away all red worms in the system at the end of the school year.
o o Allow the bms to go idle for the summer break period. Water will be added to maintain 75% moisture content. Some shredded newsprint, cardboard or wood chips added
o o Maintain feeding with alternate waste stream materials At the end of the school year a supply of wood chips or shredded newspaperlcardboard will be obtained and will be used with a supply of aged cow, sheep or horse manure.
2.11 E n d Product
Pathogen Control
Yes No
o o Sufficient care will be exercised through choice of waste streams processed to prevent introduction of pathogens to the OSCR bins and pasteurization will not be necessary.
o o Finished castings will be heated to a temperature of 160°F and held at that temperature for one hour.
Red W o r m Population Audit
Yes No
o o An audit of the red worm population will be performed on each OSCR bin at least once every 90 days.
Appendix A-6
