Element 10: Operational Control of Critical Control Points To develop and implement standard operating procedures, work management practices or other appropriate methods at all critical control points throughout the biosolids value chain to effectively manage potential environmental impacts (as identified in Element 3 procedures). Operational controls at critical control points must incorporate all legal and other adopted requirements and must consider applicable best management practices as defined in various authoritative information sources on biosolids management (e.g. NBP National Manual of Good Practice, Water Environment Federation Manuals of Practice, etc.) Operational controls include appropriate preventive maintenance procedures and work management systems for maintaining equipment, instrumentation, vehicles, and other treatment technology and process control systems associated with the Encina Wastewater Authority’s (EWA) biosolids management activities. The EWA requires that contractors establish their own operational controls consistent with their roles and responsibilities in the biosolids management activities (e.g., applies to contracts for hauling and land applying of biosolids).
