Landowner Questions

Q. How would I know if a portion of the project will be close to my property?

A.  The proposed compressor station site will be located entirely on Entergy owned property.  Federal rules require that all landowners and municipalities within one-half mile of a new compressor station be notified.  On August 3, 2017, Gulf South mailed landowner packages with details about the project and held an open house on August 24, 2017.  FERC will also send landowners a copy of the environmental assessment produced for the project, which characterizes the project's environmental impacts and evaluates other alternatives to the final site selected.

Q: Will an affected landowner be notified before construction begins?

A: Gulf South representatives will advise landowners, located within one-half mile of the compressor station, of the construction start date.  All construction activities will occur within the limits of Entergy's property located in Calcasieu Parish, Louisiana on John Stine Road and Houston River Road.

Q: How close to the existing or new facilities can the landowner build?
A: Owners of property adjacent to the compressor station may build upon their land, except for any existing agreements regarding established right-of-way on their property. Land owners who have pipeline on their property may build up to the right-of-way, but not on it.  


Q: Why didn't Gulf South choose either of the two alternative site locations as the preferred site?

A: As part of the FERC process, Gulf South is required to provide a preferred site and alternative sites for the project.  Gulf South selected the southernmost site as the preferred site due to the close proximity to Gulf South's Index 198 pipeline system and optimum distance from the Lake Charles Power Plant tie-in. Alternate Site 1's closer proximity to the power plant is less optimal for meeting the new power plants pressure requirements. Alternate Site 2 is also closer to the power plant, closer to a proposed residential community, and would have additional environmental impacts.  


Questions About Compressor Stations

Q: How large is the compressor station?
A: The new compressor station will occupy approximately 10 acres of land on a permanent basis. Additional acres of land may be used temporarily during the construction of a compressor station.

Q: How noisy is a compressor station?
A: Federal regulations require that the noise attributable to a new compressor station must not exceed a day-night average noise level of 55 dBA at any pre-existing noise-sensitive areas such as schools, hospitals, or residences.  The new compressor station is being designed to comply with this limit, and actual noise surveys will be conducted during initial operation, with results reported to FERC to document compliance. The image below reflects the noise chart depicting 55 dBA in relationship to other sources of noise.

Q: Are there special safety or fire issues associated with compressor stations?
A: All interstate natural gas facilities are required to comply with the U.S. Department of Transportation's (US DOT) Minimum Safety Standards. Natural gas transmission compressor stations are engineered, constructed, operated, and maintained in accordance with Pipeline and Hazardous Materials Safety Administration (PHMSA) safety standards. Compressor stations are constructed with multiple safety systems, such as gas and fire detection systems and emergency shutdown equipment.  In the event of an accident, these systems have been designed to ensure the station is safely shut down with minimal risk to the public or the environment.

Q.  Will there be any vibration associated with the station?  If so what is being done to minimize the impact of vibrations?
A. Gulf South works very hard to incorporate design features that minimize vibration. At times, there may be some minor localized vibration which is mostly felt within the station yard and not by those in the surrounding area.  A full vibration and pulsation analysis is performed on the compressor packages as well as the station piping both during design and after design to assess any improvements that need to be made.  It's not unusual to need to come back and install dampeners or supports after the station is running to reduce pulsation and vibrations. 

Safety Questions

Q. What kind of safeguards are taken to ensure safe operations of the pipelines and compressor stations?
A. Safety is Gulf South's number one priority in all that we do, and we are committed to operating our assets in a safe, reliable and compliant manner. To that end, Gulf South monitors its natural gas pipeline systems 24 hours a day, 7 days a week through our Pipeline Control Center.  Our compressor stations are fenced and have controlled access 24 hours a day, 7 days a week.  Natural gas pipeline systems are designed and constructed in accordance with the pipeline safety standards established by industry experts and the US DOT.

Q. How will the public be notified if there is an emergency associated with this station? 
A. The safety of our personnel and those in the surrounding community is Gulf South's top priority. In the rare event of an emergency, local first responders will be immediately notified. Gulf South will then work with them to take all necessary and appropriate actions to isolate the area and inform the public of an emergency.
