Safety and Industrial Hygiene Support

Naval Base Point Loma (NBPL), San Diego, CA

The Defense Fuel Support Point (DFSP) Fuel Depot at NBPL was comprised of 33 aboveground and 24 underground bulk fuel storage tanks constructed between 1917 and 1954. These tanks were confirmed to have releases to the subsurface. This project consisted of replacing these aging bulk fuel tanks.

GCE handled the overall safety and industrial hygiene aspects of the project. The scope of work included the review and approval of the Site Safety and Health Plan for all site work and tank work. GCE reviewed the qualifications and certifications for the Confined Space Entry Team, and provided a Certified Industrial Hygienist (CIH) who perform the personal air monitoring for the tank entry team to determine benzene exposure and developed a negative exposure assessment for the tank cleaning operation.

This bulk fuel tank demolition project was immediately adjacent to a residential neighborhood and childcare facility. With these sensitive receptors adjacent to this large demolition project, requirements were established in the Environmental Protection Plan to monitor the perimeter of the site and ensure that the general public was not exposed to elevated air contaminant concentrations or excessive noise levels. GCE prepared a Perimeter Air and Noise Monitoring Plan for the project in accordance with the Environmental Protection Plan. Contaminants of concern were identified and included Benzene, Toluene, Ethyl benzene, Xylene (BTEX); Benzo(a)pyrene, Benz(a)anthracene, Naphthalene, Polycyclic Aromatic Hydrocarbons (PAHs), Petroleum Distillates, and Particulate Matter (PM10 and PM2.5).

GCE developed an innovative three-phase strategy to reduce the cost of long term analytical sampling by establishing a correlation between field readings and laboratory data during the initial monitoring phase saving the client millions of dollars in analytical fees over the life of the project.
