Applies engineering principles, calculations and methodologies and Industrial Pretreatment Program regulations to the following: characterization and permitting of industrial and commercial facilities, for the review and evaluation of monitoring point and treatment process engineering studies and design submittals and in the evaluation of potential impacts of discharges on Metro's collection system, treatment plant operations, and Metro's ability to comply with its discharge permits and biosolids land application requirements. May function as a task manager or focus area leader. This position reports to a Principal Pretreatment Process Engineer or the Senior Pretreatment Process Engineering Manager.
Examples of Duties

  1. Conduct engineering analysis work and develop recommendations regarding discharge requests, facility characterizations, and significance evaluations - including but not limited to evaluation of industrial users and the potential of discharges to impact Metro's treatment processes, equipment, worker health and safety, and for consistency with Metro's Rules and Regulations Governing the Operation, Use, and Services of the System (R&R).
  2. Conduct review of engineering studies and designs for monitoring facilities and treatment processes and systems at industrial and commercial facilities. Complete all assigned review checklists, memos and other documents in support of review work and conclusions.
  3. Prepare permits and fact sheets which are defensible from technical and regulatory bases.
  4. Prepare process calculations, process descriptions, process drawings (PFDs, P&IDs) and general facility drawings.
  5. Prepare formal approval/denial/request for information (RFI) letters for final supervisory approval and decision.
  6. Perform site visits of industrial and commercial facilities to gather information in support of technical and regulatory evaluations and in providing technical and compliance assistant to the facilities.
  7. Perform assigned portions of complex engineering assignments.
