C)        For static pile composting, the compost bin, windrow, or other formed structure shall have a layer of carbon source a minimum of 10" deep placed on the base before the first carcass is placed in the bin.  There shall be a minimum of 10" of carbon source between the carcass and the wall or the exposed surface.  The carcass shall be covered with a minimum of 10" of carbon source.  The carbon source shall be added to the pile as composting begins, daily or as frequently as needed to sustain a 10" cover of carbon source over all carcasses in the structure's uppermost layer.

 

D)        A compost thermometer with a probe at least 36" long shall be obtained and used daily to measure the temperature of the compost.  The compost temperature should reach 135 to 160° degrees F. (57° to 71° C.) and be recorded daily.  Compost temperature indicates microbial activity and stage of composting process.  The composting process shall be managed in such a way that the heating and decomposition can proceed to completion.  If aerobic composting does not begin with 7 days, i.e., if temperatures do not rise above 135° F., the compost pile or windrow shall be turned and/or moisture content of the carbon source adjusted to allow the process to proceed.  Temperature records shall be available for examination until the compost is disposed of as in subsection (e)(6)(G).

 

E)        For bin composting, all compost from the primary bin shall be allowed to undergo a second composting phase as follows:

 

i)          When the temperature surrounding the last carcass placed in the composter drops below 130° F. (typically up to 3 months after the last carcass addition), the compost in that bin shall be transferred to a second bin and allowed to reheat, through a second composting cycle.  Moisture shall be added to the compost as needed to promote further composting activity.

 

ii)         Compost shall remain in the second bin for the duration of the secondary composting cycle (typically 3 months).  Temperature of the compost shall be measured using the compost thermometer to monitor the composting process.

 

F)         Finished compost shall be agronomically distributed over land under cultivation or reused in the composting process.  Finished compost may be returned to the primary composting bin in the ratio of up to 50% finished compost to fresh carbon source.  For the purpose of this subsection (e)(6)(G), the agronomic rate is the annual application rate of swine compost, either alone or in combination with other nutrient supplying materials that is necessary to achieve a reasonable crop yield without exceeding crop nutrient requirements.

 

f)         Disposal of Cattle, Equine, Cervidae, Sheep, Goats, or Other Small Animals by Composting.  Persons disposing of cattle, equine, cervidae, sheep, goats, or other small animals by means of composting shall comply with the following requirements:
