Existing facilities modified after this date must include provisions to address these regulations.
(b) The minimum treatment processes required are mixing, clarification, conventional filtration and disinfection. Any deviation must have written Departmental approval.
(c) A pilot study is required to demonstrate the effectiveness of the process to achieve the required log removals of Giardia lamblia cyst, Cryptosporidium oocysts, and viruses as specified in rule 335-7-6-.04(e) on the proposed raw water source. The duration of the pilot study must be a minimum of 30 consecutive days. The pilot study shall be conducted during a time when raw water turbidity is historically at its highest. A report on the pilot study must be submitted to the Department and approval obtained prior to the submittal of an application for a permit to construct.
(d) The Department will determine minimum design requirements for each individual treatment technology as they are proposed. These design requirements will be based on manufacturer recommendations and/or the results of the pilot study for the proposed treatment technology.
