Comment: The initial reduction is performed by aerobic digestion. Final reduction is achieved by running
the digested sludge through a furnace at consistent heat for a controlled time. The heat
reduces the sludge to a Class "A" residual that is available to be used by the public.
Sampling
Describe sampling:
Composite sampling is performed at the discharge point of the furnanace to verify PVAR has been achieved.
Yes No NA NE
Is sampling adequate?
Is sampling representative?
Comment: The laboratory analytical data of the quarterly sampling events indicate the sampling is
representative of the residuals being produced at the WWTP.
Transport
Is a copy of the permit in the transport vehicle?
Is a copy of the spill control plan in the vehicle?
Is the spill control plan satisfactory?
