June 25 (Reuters) - U.S. liquefied natural gas (LNG) company Venture Global LNG on Tuesday received U.S. regulatory approval to re-introduce hazardous fluids into Heat Recovery Steam Generator (HRSG 375) at the company's Calcasieu Pass LNG export plant in Louisiana.

The approval from the U.S. Federal Energy Regulatory Commission (FERC) was the latest filing in Venture Global's effort to bring Calcasieu to commercial service.

FERC noted in the filing that Venture Global must comply with all applicable remaining terms and conditions of the order, as well as procedures stipulated in previous filings.

Venture Global LNG's Calcasieu Pass plant has been at the center of a long-running dispute involving energy companies including BP, Shell and others over access to LNG from the plant.

Earlier this month, U.S. regulators ordered Venture Global LNG to provide documents about the mechanical problems and startup of a Louisiana plant to its customers.

Even though Calcasieu has been exporting LNG since March 2022, LNG cargoes usually do not belong to customers until a project is commercial.

FERC mentioned that this approval does not grant Venture Global the authority to place other project facilities in service at the LNG terminal. (Reporting by Anjana Anil in Bengaluru Editing by Marguerita Choy)
