Venture Global Plaquemines LNG Submits Noise Monitoring Report to Federal Energy Regulatory Commission

Strategic Insights -

Washington-based Venture Global Plaquemines LNG, LLC has submitted a Nighttime Noise Monitoring Report to the Federal Energy Regulatory Commission for its liquefied natural gas facilities in Plaquemines Parish, Louisiana. The report, filed on June 27, 2025, covers a period from June 8 to June 21, 2025, and details the nighttime noise monitoring results from NSA Nos. 2 and 6. According to the report, project-related construction nighttime sound level contributions did not exceed the established sound level limit at either noise sensitive area. However, measured sound levels at NSA2 and NSA6 exceeded the established sound level limits on some nights due to high-frequency noise associated with frogs and insects.
