Operator Certification Program - Wastewater Treatment Plant Classification
The Water Code gives the OOC responsibility for classifying all publicly owned wastewater treatment plants and private plants regulated by the PUC. Agencies may not "class" their own plants nor can the Regional Boards assign the designations.
The OOC asks that the Chief Plant Operator (CPO) complete a "Wastewater Treatment Plant Class Data Form". That form along with an organization chart, flow diagram of the plant, job descriptions for all personnel classifications and duty rosters must be submitted to the OOC. Once the OOC reviews the information, the CPO will be sent a letter indicating the classification and appropriate operator grades. However, the OOC does not specify how many operators must be employed at each grade.
