Overview
The Arkansas River HDD Crossing Project 2 is an operational gas pipeline in Little Rock, Arkansas, United States. It serves as a critical infrastructure component for natural gas transmission under the Arkansas River.
The Arkansas River HDD Crossing Project 2 is a gas pipeline facility located in Little Rock, Pulaski County, Arkansas, United States. The facility is operational and plays a key role in the regional natural gas transmission network, crossing under the Arkansas River via horizontal directional drilling (HDD) technology. As a gas pipeline, this facility operates under the regulatory oversight of the Pipeline and Hazardous Materials Safety Administration (PHMSA) and complies with 49 CFR Part 192, which governs gas pipeline safety. The use of HDD for river crossings is a common technique to minimize environmental impact and protect waterway integrity. The pipeline's NAICS code 486210 indicates it is part of the pipeline transportation of natural gas sector. The Arkansas River HDD Crossing Project 2 enhances the resilience and capacity of the natural gas grid in central Arkansas, supporting residential, commercial, and industrial energy needs in the Little Rock metropolitan area. Its strategic location near the intersection of Mills Street and Compton Street underscores its role in connecting supply sources to demand centers.
Environmental context
The pipeline crosses the Arkansas River, a major waterway in the region, necessitating careful construction and monitoring to protect aquatic habitats and water quality. The HDD method reduces surface disturbance and avoids direct impacts on the riverbed. Proximity to populated areas in Little Rock requires robust safety measures, including cathodic protection and regular inspections to prevent leaks and ensure long-term integrity.
