Project overview
The Carnation Project is a system upgrade proposed by Texas Gas Transmission, LLC ("Texas Gas") to meet rising natural gas demand in the tri-state area. By enhancing compression and regulation capabilities at existing facilities, the project will improve the capacity and efficiency of Texas Gas’s pipeline system. These enhancements will help serve residential, commercial and industrial customers while supporting regional energy reliability.

Crosby-Harrison Compressor Station Considerations
The Crosby-Harrison Compressor Station was built in 2015 in a quiet, undeveloped area. Over time, nearby communities have grown, which influences how we design and operate our facilities.
As part of the Carnation Project, Texas Gas is implementing upgrades to reduce sound levels and enhance environmental performance. These efforts reflect our commitment to responsible operations and consideration for nearby communities. To achieve this, we’re implementing several improvements:
- Insulating piping: All above-ground pipes 6 inches or larger will be wrapped in high-quality acoustic insulation to reduce noise.
- Quieter equipment: We are investing in low-noise gas coolers and silencers that can reduce sound by up to 20 dBA during gas regulating activities.
- Enclosed compressors: We are modifying the existing compressor unit building to accommodate the new proposed compressor unit, ensuring it remains fully enclosed to help maintain a low-noise profile.
- Smart placement: We are conducting a dispersion study to help us place equipment like silencers in the most effective locations for reducing noise and emissions.
Additional benefits include:
- Non-reflective materials: New coolers will be made of non-reflective galvanized steel to minimize visual impact.
- Low-impact lighting: Lighting will remain manually operated for use at night to limit unnecessary light.
A noise study graphic is provided below to illustrate projected sound levels once the upgraded facilities are in service. The white line outlines our property boundary, while the blue and green lines show how noise levels disperse outward, demonstrating a sharp drop-off in sound intensity at the fence line and beyond.
Compressor Station Noise Information
Compressor stations are highly regulated to ensure minimal impact on surrounding communities. Texas Gas adheres strictly to the Federal Energy Regulatory Commission (FERC) guidelines, including the requirement that noise levels do not exceed 55 decibels (dBA) at the nearest noise-sensitive area, such as a home or business. This standard is comparable to the sound of a normal conversation, helping ensure a quiet and safe environment for nearby residents. The Carnation Project is being designed to meet the FERC’s 55dBA noise requirement. Noise surveys will be conducted before and after construction to verify compliance and ensure that operations remain unobtrusive to surrounding communities.
The flyers and links below include safety information on pipelines and compressor stations. These materials include helpful details about the role of compressor stations in natural gas transportation, along with the safety features built into their design and operation.

The Carnation Project involves the installation of natural gas infrastructure at two existing Texas Gas facilities in Hamilton County, Ohio. Specifically, the project will add a second compressor unit at the Crosby-Harrison Compressor Station to boost pipeline pressure and flow capacity. Additionally, it will upgrade gas regulation equipment at the New Haven Regulator Station to improve pressure control and system reliability. These installations are designed to support increased regional demand while incorporating noise reduction measures (such as acoustic insulation and low-noise coolers), emissions-reducing technologies, and smart equipment placement to minimize environmental and community impact.
Key Project Components
Compressor Station Enhancements: Installation of additional compression equipment at the existing Crosby-Harrison Compressor Station in Hamilton County, OH.
Regulator Station Upgrades: Modifications to the existing Harrison Regulator Station to improve pressure control and system performance.
System Optimization: Designed to improve flow and delivery of natural gas to meet growing demand in southwestern Ohio, northern Kentucky and eastern Indiana.
Construction / Operation / Safety
The Carnation Project will be constructed and operated in accordance with rigorous safety and engineering standards established by the Department of Transportation (DOT) and the Federal Energy Regulatory Commission (FERC). During construction, qualified inspectors will oversee each phase to ensure compliance with safety protocols, including thorough testing of equipment and systems before facilities become operational. Compressor stations will be equipped with emergency shutdown systems and monitored 24/7 to track gas flow, pressure and equipment conditions.
Operational safety will be reinforced through regular inspections and maintenance to detect and address potential issues early. Texas Gas also engages with local communities through public awareness programs, providing safety information and emergency contact details. Compressor stations are designed to minimize risk to surrounding areas and include features such as automatic and manual valves for rapid isolation, along with coordination with first responders to help ensure preparedness.
Environmental Considerations / Compression Station Noise Information
Environmental Considerations
Texas Gas is committed to responsible environmental stewardship throughout the Carnation Project. Compressor station upgrades will be designed and operated in accordance with federal and state environmental regulations, including permitting and compliance requirements set by the Environmental Protection Agency (EPA) and other relevant agencies. These standards help ensure that construction and operations are conducted in a way that protects surrounding communities and natural resources.
The timeline below reflects key milestones in the engagement, permitting, and construction processes for the Carnation Project. We will continue to update this section as the project progresses.

Texas Gas is regulated by the Federal Energy Regulatory Commission (FERC), a federal agency that oversees the transportation of natural gas projects that cross state lines. The FERC’s role is to ensure these projects are safe, environmentally responsible, and in the public interest. Before any major project can move forward, the FERC reviews project plans in detail and decides whether it meets all the necessary standards.
We plan to submit a formal application for the Carnation Project in the fourth quarter of 2025, initiating FERC’s environmental review and public engagement process.
The FERC will notify applicable stakeholders, solicit feedback, and allow for public comment throughout the application review process.
