This proposal outlines a strategic partnership between Sun Devil and APS for the development of a 490-mile pipeline from the San Juan Basin to Phoenix, AZ. The project aims to minimize costs and environmental impact while maximizing the value of existing assets. Key design features include 36-inch diameter pipe, five new compressor stations, and a capacity of 780,000 MMBtu/d. Targeting an in-service date in Q3 2004, the project offers competitive rates and low-cost expandability, ensuring a reliable and flexible gas supply for the region.
