ONEOK Inc. subsidiary Saguaro Connector Pipeline LLC (Saguaro) has filed a Presidential Permit application with the Federal Energy Regulatory Commission (FERC) to construct and operate facilities to export natural gas at a new international border crossing at the US/Mexico in Hudspeth County, Texas.

The proposed border facilities would connect upstream with a potential intrastate natural gas pipeline, the Saguaro Connector Pipeline, which would be designed to transport natural gas from ONEOK’s existing WesTex intrastate natural gas pipeline system in the Permian Basin in West Texas to Mexico. Additionally, the proposed border facilities would connect at the International Boundary with a new pipeline under development in Mexico for delivery to an export facility on the West Coast of Mexico.

The potential Saguaro Connector Pipeline would consist of approximately 155 miles (249 km) of natural gas pipeline originating at the Waha Hub in Pecos County, Texas.

The Border Facilities will have an ultimate design capacity of approximately 2.834 b/cfd (80.2 x 106 m3/d) and up to a maximum allowable operating pressure of approximately 1480 psi (102 bar).

If approved by FERC, Saguaro will construct and operate two new compressor stations. The first compressor station will be located at the beginning of the pipeline near Coyanosa, Texas. The second compressor station will be located on private land that will be acquired by Saguaro at an intermediate point on the pipeline (currently planned for approximately MP 113). The horsepower for each compressor station will be between 55,000 and 100,000 hp (41 and 74.6 MW).

Final investment decision on the potential pipeline is expected by mid-2023.
