Transwestern Pipeline Staff Protests Green Chile Project Blanket Certificate
Summary
FERC staff filed a protest against Transwestern Pipeline Company's proposed blanket certificate activity for the Green Chile Project, a 17.77-mile natural gas transmission pipeline lateral in Doña Ana County, New Mexico. Staff cited the company's failure to provide documentation from the New Mexico State Historic Preservation Office demonstrating compliance with the National Historic Preservation Act, as required under 18 CFR 157.206(b)(3)(ii) and 157.208(c)(9). Pursuant to 18 CFR 157.205(f), the protested prior notice filing is treated as a case-specific application under NGA section 7.
What changed
FERC staff filed a protest under 18 CFR Part 157, subpart F, against Transwestern Pipeline Company's prior notice filing for the Green Chile Project, a 17.77-mile, 24-inch natural gas transmission pipeline lateral with metering facilities in Doña Ana County, New Mexico. The protest cited non-compliance with the National Historic Preservation Act due to missing State Historic Preservation Office documentation. Under 18 CFR 157.205(f), the protested filing is automatically treated as a case-specific application under NGA section 7, unless the protest is withdrawn within 30 days after protests were due (April 13, 2026).
Affected parties—Transwestern Pipeline Company and other energy infrastructure developers seeking blanket certificate authority under Part 157—should ensure all required environmental and cultural resource documentation is included with filings to avoid conversion to more time-intensive case-specific applications. This protest demonstrates FERC staff's continued attention to cultural resource compliance in pipeline approval proceedings.
What to do next
- Provide documentation from the New Mexico State Historic Preservation Office showing "no historic properties" or "no historic properties affected" findings to address cultural resource compliance requirements under 18 CFR 157.206(b)(3)(ii) and 157.208(c)(9)

- [Docket No. CP26-80-000] Federal Energy Regulatory Commission (FERC or Commission) staff (Protestor) hereby protests the prior notice request filed under the provisions of the Commission's regulations at Part 157, subpart F, by Transwestern Pipeline Company, LLC (Transwestern) on January 29, 2026, in the above-referenced docket. Pursuant to its Part 157, subpart F, blanket certificate authority, Transwestern proposes to construct and operate approximately a 17.77-mile-long, 24-inch-diameter, natural gas transmission pipeline lateral, two metering facilities, and appurtenances for the Green Chile Project (Project), in Doña Ana County, New Mexico. Section 157.205(f) provides that a protested prior notice filing shall be treated as though it had filed a case-specific application under NGA section 7, unless, pursuant to section 157.205(g), the protestor withdraws its protest within 30 days after protests were due.
Protestor notes that Transwestern did not provide a copy of a finding by the New Mexico State Historic Preservation Office of “no historic properties” or “no historic properties affected.” This documentation is necessary to demonstrate the Project's compliance with the National Historic Preservation Act, as required under the Commission's regulations at sections 157.206(b)(3)(ii) and 157.208(c)(9) and Appendix II of subpart F. Without this documentation, the environmental concerns cannot be adequately addressed before the protest period expires on April 13, 2026.
Authority: 18 CFR 2.1.
Dated: April 13, 2026.

Secretary.
