Comment: Initial reduction is performed by aerobic digestion. PVAR is performed in vessel by time and
temperature to achieve maximum pathogen reduction.
The composted material continues to achieve further reduction on the curing pad.

Comment: Time on temperature records are presented in the AR. The records indicate the vessels are
achieving a higher temperature than required to generate further pathogen reduction.
Sampling
Describe sampling:
There are seven sampling ports located throughout the tunnel reactor (vessel). Discrete temperature
measurements can be collected throughout the vessel.
Bi-monthly sampling or fecal coliform by standard method SM92210E is employed to measure the fecal
coliform reduction.
Is sampling adequate?
Is sampling representative?
