Abstract:
This document is intended to provide information to assist anyone who needs to evaluate the performance of a biological treatment unit that does not meet the definition of an enhanced biological treatment system or enhanced biological treatment process" (not considered a "thoroughly mixed treatment unit") because of limitations in overall unit mixing. This document is intended as support for evaluation of biological units with multiple mixing zones. The evaluation of the biological treatment unit can be used for certain compliance demonstration provisions in connection with Appendix C of 40 CFR part 63. Potential users of this document include owners and operators of sources who must demonstrate compliance with the requirements for biological treatment units presented in Appendix C of 40 CFR part 63, as well as enforcement personnel evaluating whether a specific biological treatment process meets the performance criteria required for regulation compliance.
