ARKANSAS RIVER HDD CROSSING PROJECT 4 is a gas pipeline facility located in Little Rock, Pulaski County, Arkansas, United States. The facility is operational and serves as a key component of the natural gas transmission infrastructure in the region, utilizing horizontal directional drilling (HDD) to cross the Arkansas River. The facility operates under the regulatory oversight of the Pipeline and Hazardous Materials Safety Administration (PHMSA) and complies with 49 CFR Part 192 for gas pipeline safety. As part of the U.S. natural gas network, it contributes to the reliable delivery of natural gas to industrial, commercial, and residential consumers in central Arkansas. The Arkansas River crossing is a critical link in the regional gas transmission grid, ensuring supply continuity across the river. The HDD method minimizes environmental disturbance during construction and reduces long-term maintenance risks. The facility's location near Little Rock supports the energy needs of the state's capital and surrounding areas.
Environmental context
The facility crosses the Arkansas River, a major waterway in the region. Pipeline crossings of waterways require careful design to protect aquatic habitats and water quality. The HDD method reduces surface disruption and sediment runoff during installation. Ongoing monitoring and cathodic protection systems help prevent corrosion and leaks, safeguarding the river ecosystem.
Frequently asked questions
The facility is located southeast of the intersection of E 6th St and Townsend St in Little Rock, Pulaski County, Arkansas, United States.
It is a natural gas pipeline facility that uses horizontal directional drilling to cross the Arkansas River, transmitting natural gas as part of the regional pipeline network.
Gas pipelines in the U.S. are regulated by the Pipeline and Hazardous Materials Safety Administration (PHMSA) under 49 CFR Part 192, which covers design, construction, operation, and maintenance safety standards.
HDD is a trenchless method used to install pipelines beneath obstacles like rivers. It involves drilling a pilot hole and enlarging it to pull the pipeline through, minimizing surface disruption and environmental impact.
River crossings require special design to prevent leaks and withstand water currents. The HDD method reduces risk by placing the pipe deep below the riverbed, and cathodic protection systems are used to prevent corrosion.
