This Enhanced Integrity Investigation and Assessment provided a more detailed inspection and analysis of the DLA capitalized JP-8 fuel piping located at Joint Base Charleston, South Carolina. The assessment focused on several items of concern that were identified during the development of the initial “Integrity Management Plan (IMP) – POL Pipelines” at this facility.
The overall scope of this project was to further assess several high-risk aspects of the aboveground and underground piping system at the facility. These aspects included the aboveground piping, soil-to-air, and concrete-to-air interfaces associated with storage Tank #5; an exposed portion of pipeline and soil-to-air-interfaces of the 8-inch cross base transfer pipeline; and the underground transfer and hydrant piping within the various valve and hydrant pits. Additionally, the assessment included Close Interval Potential (CIP) and Alternating Current Voltage Gradient (ACVG) cathodic protection surveys. The underground piping was then excavated and inspected at various locations based on the results of the cathodic protection surveys to locate any possible anomalies.
At the conclusion of the inspection, the facility’s initial “Integrity Management Plan – POL Pipelines” was amended by adding all of the pertinent information and any deficiencies found during the field investigation. This included recommended repairs and budgetary cost estimates to develop the final version of the document.
