If not, you should acquire a copy of the Certification Law, Minnesota Statute 1971, Section 115.71, and the Rules 9400.0200 to 9400.1400. A wastewater treatment facility means any plant, disposal field, lagoon, or other works, installed for the purpose of collecting, pumping, treating, stabilizing or disposing of sewage, which is actually used or intended for use by the public or by any considerable number of persons. A type S facility means a system of collection, pumping, and conveyance facilities distinctly separate in operation from a facility which treats, stabilizes, or disposes the wastewater. Where a type S facility is not distinctly separate, it is considered to be part of the treatment facility. Direct responsibility means the wastewater operator having full and active responsibility for the operation of a portion of, or all of, a facility or wastewater collection system.
