Landowner AND oTHER FAQ's


Texas Gas Transmission, LLC

Texas Gas is an interstate natural gas pipeline company that is regulated by the Federal Energy Regulatory Commission (FERC) under the Natural Gas Act. Our existing pipeline system is composed of approximately 6,100 miles extending from Ohio to the Gulf Coast. We have a strong regional presence with approximately 300 employees, most of whom work in our regional headquarters in Owensboro, Kentucky.


Northern Supply Access Project

The Northern Supply Access Project, which includes construction of a the new compressor station in Hamilton County, Ohio, will allow Texas Gas to flow natural gas north to south, while retaining the existing capability to flow natural gas south to north. The new station in Crosby Township is part of an expansion of Texas Gas’ existing natural gas facilities through the Northern Supply Access Project.   Texas Gas has two 26-inch pipelines running through Hamilton County and, for example, currently provides natural gas to the local distribution company (LDC) that serves the City of Harrison.



Positive Long Term Impact on the Community

During the approximately seven-month construction period of the project, Texas Gas will need approximately 20 ongoing construction personnel and up to another 80 personnel at key points during the process. Once complete, the new compressor station will create two or three permanent local jobs and will create incremental ad valorem/property tax revenue for Hamilton County, a portion of which will be allocated directly to schools.


Our Commitment to Safety

Safety is our top priority. Our compressor stations and pipelines are monitored 24 hours a day, 7 days a week at our Pipeline Control Center in Owensboro, Kentucky.  They will be regularly inspected from both the ground and with aerial patrols. All of our compressor stations and pipelines undergo periodic maintenance inspections, including leak surveys and valve and safety device inspections.


Keeping Local Residents Informed

Prior to being placed in service, Texas Gas will train local first responders so that they are prepared to deal with any events, however unlikely they may be.  Line markers are posted along right-of-way to identify the pipeline’s presence, and all of our above-ground facilities are clearly marked and fenced. Written safety information is distributed annually to neighbors, residents and businesses located near our facilities, as well as emergency officials and excavators.


Being a Good Neighbor

FERC requires compressor stations not exceed a day-night average noise level of 55 A-weighted decibels (dBA) at any pre-existing noise sensitive area such as schools, hospitals, or residences.  For reference, normal conversation typically take place in the 55-65 dBA range, while household vacuum cleaners typically operate in the 60-85 dBA range.





General Questions


Q. What is the scope of the Northern Supply Access Project and what company owns it?

A.  The Northern Supply Access Project is a project of Texas Gas Transmission, LLC (Texas Gas), a natural gas company that is regulated by FERC.  The project will consist of the construction of a new compressor station in Hamilton County, Ohio (the Harrison Compressor Station); installation of gas cooling facilities at an existing compressor station in Dearborn County, Indiana; installation of a new gas turbine compressor and classification of certain reciprocating compressors as operational spares at an existing compressor station in Morehouse Parish, Louisiana; and modification of yard and station piping at seven existing compressor stations located in Lawrence County, Indiana; Jefferson County, Kentucky; Breckinridge County, Kentucky; Webster County, Kentucky; Tipton County, Tennessee; Coahoma County, Mississippi; and Morehouse Parish, Louisiana. The Project will allow Texas Gas to flow proposed quantities of natural gas north to south, while retaining the existing capability to flow natural gas south to north.   A map may be accessed by clicking here.


Q. What is the status of the Northern Supply Access Project?

A. Construction on the facilities with firm transportation agreements began in May 2016 and were put into service in March 2017.  In April 2017, Texas Gas filed a request for an extension of time to complete the re-marketing and construction of the facilities necessary for the remaining 100 MMBtu per day of uncontracted capacity.  FERC granted the extension of time for one year, until and including March 24, 2019 to complete construction of the authorized facilities and make them available for service.  


Q. Is the addition of this new compressor station related to the new pipeline project being developed by Duke Energy of Ohio elsewhere in Hamilton County?

A. No, Duke Energy of Ohio is not a customer of the Northern Supply Access Project, of which this compressor station is a part.  But they are a customer of Texas Gas.


Landowner Questions


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

A. Federal rules require that all landowners and municipalities within one-half mile of a new compressor station be notified.  Texas Gas and FERC began notifying landowners directly several times beginning in June 2015.  In addition, those landowners were sent a copy of FERC's environmental assessment produced for the project, which characterized the project’s environmental impacts and evaluated other alternatives to the final site selected for the new compressor station in Crosby Township.  


Q: Will an affected landowner be notified before construction begins on his or her property?

A: Texas Gas representatives will advise a landowner of the construction start date affecting his or her property.  This will allow the landowner to schedule farming or other activities in ways that minimize inconvenience for both parties.  However, the availability of equipment, weather, and other factors can be unpredictable and might affect the actual start date. All landowners will be notified of any significant changes to the construction timeline.


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 with regard to 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.


Questions About Compressor Stations


Q: How large is the compressor station?

A: The new compressor station will use about 12 permanent acres.


Q: How noisy is a compressor station?

A: The noise attributable to a new compressor station, or any modifications to existing stations, 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 or modified facilities have been 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. 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. Why is a new compressor station being built near Harrison, Ohio?

A. The new compressor station in Crosby Township near Harrison is part of an expansion of Texas Gas’ existing natural gas facilities through the Northern Supply Access Project.   Texas Gas has two 26-inch pipelines running through Hamilton and our system-design models dictated that the station must be located along the pipelines in this general area in order for Texas Gas to provide additional gas service for the customers of the project.


Q.  Will there be any vibration associated with the station?  If so what is being done to minimize the impact of vibrations?

A. Texas Gas works very hard to incorporate design features that minimize vibration. At times, there may be some minor localized vibration which are mostly felt within the station yard and not by those in the surrounding area. 

Q. How are you screening this visually?  Will there be fence/landscape large enough at time of building?  

A. Before placing the facility in service, the site will be fenced and have controlled access 24 hours a day, 7 days a week.  The site is currently visually screened by trees and brush to the north, west and south.  In addition, Texas Gas has proposed additional new tree screening to the east and will augment the current tree “wind-row” screen on the north with additional visual screening.  The final landscaping plan will be consistent with Crosby Township zoning regulations.


Emissions Questions


Q. Are any of the emissions regulated? Who will measure/monitor them and how will they be measured/monitored?

A. Yes, the facility has secured a Final Permit-to-Install and Operate the Compressor Station (Permit) from the Ohio Environmental Protection Agency (Ohio EPA) as administered by the Southwest Ohio Air Quality Agency (SOAQA), which is the air permitting authority for the area.  Ohio EPA rules are generally equal to or more stringent than Federal Environmental Protection Agency (US EPA) standards.  Ohio EPA’s permitting program has been reviewed by the US EPA and approved as part of the State Implementation Program for safeguarding air quality.  As part of the permitting, Ohio EPA determined the proposed equipment meets the Best Available Technology (BAT) requirements.  These emissions will be periodically sampled by both Texas Gas and Ohio EPA and also subject to periodic audits.


Q. What emissions are expected and at what concentrations?

A. Texas Gas goes to great lengths to minimize emissions from our facilities so they are at levels far below major source thresholds of 100 tons per year established by law. The actual emissions depend on how much the stationary turbine actually runs, and the gasses that could be emitted include Nitrogen Oxides (NOx), Carbon Monoxide (CO), Volatile Organic Chemicals (VOCs), Sulphur Dioxide (SO2), and Particulate Matter (PM10 and PM2.5).  The Permit addresses these emission levels, applicable requirements, dispersion modeling results, and the BAT analysis for the facilities, by emission. 


Q. What is being done to minimize emissions?

A. Texas Gas has purchased from Solar Turbines Incorporated, based in San Diego, California, some of the lowest-emitting NOx stationary turbine units commercially available.  NOx emissions from the each of the proposed turbines are guaranteed to be a maximum of 15 parts per million by volume on a dry basis (ppmvd).  The Federal emission standard for new stationary turbines is 25 ppmvd. 


Q. What would be the maximum concentration of the regulated air emission(s) during any one hour of operation?

A. As a requirement of the Permit, Texas Gas modeled NO2 impacts – which have a 1-hour standard - combined with the background ambient concentration.  That impact is 39.8% of the 1-hour National Ambient Air Quality Standard (NAAQS) for NO2.  This analysis was also reviewed and accepted by SOAQA. It is important to keep in mind that this represents the maximum possible emission and not those seen during regular operations. The maximum possible emission is within state and federal guidelines.


Q. Does this facility have the potential to occasionally release emissions above the regulatory limits? 

A. Texas Gas takes the safe and responsible operation of all of its facilities very seriously. Under normal operating circumstances, all emissions from the facility would be well within state and federal guidelines. However, in the event of a very rare occurrence—and most likely in the event of an equipment failure—it is possible that higher emissions could occur for a short period of time.  In the event of a failure, Texas Gas would immediately take the necessary steps to protect the public.  Federal rules require Texas Gas to operate and maintain the stationary combustion turbine, air pollution equipment, and monitoring equipment in a manner consistent with good air pollution control practices for minimizing emissions at all times including startup, shutdown, and malfunction.


Safety Questions


Q. What kind of safeguards are taken to ensure safe operations of the pipelines and compressor stations?

A. Safety is our 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, Texas Gas monitors its natural gas pipeline systems 24 hours a day, 7 days a week through our Pipeline Control Center in Owensboro, Kentucky.  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 our top priority. In the rare event of an emergency, local first responders will be immediately notified. Texas Gas will then work with them to take all necessary and appropriate actions to isolate the area and inform the public of an emergency.
