Given these factors and after examining the recommended holding times and associated studies referenced in SW-846 and interpretations of how holding times are evaluated across other EPA programs, the Office of Resource Conservation and Recovery (ORCR) has decided to clarify that the recommended holding times in SW-846 Chapter 32 (Table 3-2) and Chapter 4 (Table 4-1). WASTEWATER, BACTERIOLOGICAL. Holding time studies referenced in SW-846 Chapter 41 do not provide a clear basis to discriminate between acceptable and unacceptable measurements within a small tolerance of the nominal holding time, such as within a few hours for holding times of 7 days. Special Publications.
