1. Aquatic Resource Data Quality Validation

    A natural gas client experienced delays with permit reviews submitted by other consulting firms because of concerns with the quality and reliability of their wetland data. Permit applications submitted by RETTEW for the client did not have similar delays in review. As a result, RETTEW provided quality control (QC) field reviews of stream and wetland…

  2. Pipeline Boundary Survey for 300 Line

    A natural gas client planned to upgrade its natural gas pipeline transporting raw material to the Northeast. The client’s goal was to enlarge the pipe size because of the increased demand in the region.

  3. Pipeline Patrol and Inspection

    An exploration and production client acquired a 37-mile natural gas pipeline collection system that had been depressurized and shut down for more than two years. Prior to reactivating and bringing the gathering system online, the client needed to bring the pipeline into compliance with government and safety regulations. Although they typically provided these inspection services…

  4. Rover Pipeline

    The Rover Pipeline is a 711-mile transmission pipeline project that runs through portions of West Virginia, Pennsylvania, and Ohio, and extends 75 miles into Michigan.

  8. High-Angle Utility Locating

    A high-pressure natural gas pipeline located in a right-of-way between two existing pipelines required inspection to evaluate potential flaws and any need for repair. Prior to excavation, the client needed to adhere to PA One Call requirements to mark their assets. A portion of the right-of-way was brush- and snow-covered steep terrain, creating accessibility challenges…

  9. Midstream Pipeline Rerouting

    A natural gas client acquired a planned pipeline, with routing and landowner agreements already in place. However, the existing route would take months of additional regulatory review time, and the client was eager to get the gas to market as quickly as possible. RETTEW tackled the many steps to reroute the pipeline, avoiding the extra…
