The document is a 2022 King-Murray Operating Company Annual Pipe to Soil Survey report for the OGS Holopaw Test Site, conducted on 4/27/24. The survey documents electrical measurements and cathodic protection (CP) system assessments for various pipeline station locations, including meter and regulator stations. Measurements were taken at multiple points along the pipeline, recording pipe-to-soil potential readings and voltage measurements at different station locations such as meter station outlet rectifier, regulator station inlet, and various skid inlets and outlets.

The survey report indicates that the CP system is in good order, with a new updated rectifier and new test stations installed. The technician, James McAllister, noted electrical isolation flange measurements and provided overall system status. The document includes detailed voltage readings at specific pipeline points, with measurements ranging from -0.398 to -1.189 volts, and demonstrates a comprehensive assessment of the pipeline's electrical integrity and corrosion protection infrastructure.
