The meaning of this subsection is not clear. It requires, “Dosing of the treatment unit or treatment system shall accommodate the design peak flow within the treatment unit’s rated capacity.” How is “design peak flow” determined and by whom? How is the treatment unit’s rated capacity defined and by whom? Does this requirement mean that the treatment unit must be sized to accommodate “peak” flows rather than “sewage flows” established at 12VAC5-610-670? Or does the term “peak flows” mean the same thing as the “sewage flows” established at § -610-670?
Is this basically a treatment unit minimum sizing rule? Or is the objective to regulate some other aspect of the design such as the dosing regimen?
It’s hard to know what the effect of this requirement would be unless terms are better defined and further clarification is provided.
