Rule 391-3-6-.12. Wastewater Treatment Plant Classification

The following wastewater treatment plant classifications are established as minimum levels. Any plants which do not f it one of these classifications will be classified on a case-by-case basis by the Division. The Division may classify any plant at a higher level based on the complexity or location of the plant or critical uses of the receiving waters.

PLANT TYPE PERMITTED FLOW (MGD) CLASSIFICATION (RESPONSIBLE CHARGE OPERATOR) Biological [suspended growth (i.e., activated sludge), fixed film (i.e., trickling filter) or land application]. See note 1 > 3.0 Class I Biological [suspended growth (i.e., activated sludge), fixed film (i.e., trickling filter) or land application]. See note 1 > 1.0 to 3.0 Class II Biological [suspended growth (i.e., activated sludge), fixed film (i.e., trickling filter) or land application]. See note 1 1.0 Class III Biological, waste stabilization pondsand constructed Wetlands. See Note 1 Any Class IV Industrial Any Class Industrial or Biological Class I, II, or III

Note 1. This does not apply to industrial or industrial pretreatment facilities. It applies to municipa l and private wastewater treatment plants treating domestic or primarily domestic wastewaters. However, if the industrial treatment system is a biological system, it is recommended that the operator obtain a biological certification. Those industries who have a physical/chemical treatment system should have their operators obtain a Class Industrial certification.
