Gas Planning Engineer I ($73,182.93 - $102,518.83 annually): A Gas Planning Engineer I under general direction, learns to perform the full scope of duties of a Gas Planning Engineer II through an on-the-job training program. Duties that are learned include: performing professional and specialized engineering work related to gas infrastructure planning, operations, and functioning of the City's natural gas systems. The primary responsibility of this classification is to ensure the short-term and long-term operational integrity by ensuring that there is sufficient capability within the natural gas distribution system to meet forecasted customer requirements. The incumbent learns gas system modeling for short-term and long-term planning using GasWorks software to perform system network analysis and learns to use this analysis to develop master plans, implement design improvements, and plans to meet immediate or near-term needs as well as develop the City's Gas Master Plan for long-term requirements. This class will assist in setting gas system improvement priorities, prepare cost estimates, provide budgetary input related to planning, operations, and the function of short- and long-term design of the natural gas system; and develop material specifications for all materials used in the City's natural gas systems. This class performs related duties as required. The Gas Planning Engineer I learns to perform specialized engineering and technical work related to the planning, design, and operation of the City's natural gas system. The Gas Planning Engineer I classification differs from the Gas Planning Engineer II by the latter having significant gas planning and system modeling/design experience and a desirable registration in the state of Arizona as a Professional Engineer and performing more difficult and varied professional engineering work assignments, with minimal direct supervision. Employees in this class may progress by noncompetitive promotion to Gas Planning Engineer II upon meeting the specific criteria-based promotion requirements.
