Bay Road Holdings LLC (formerly Romic Environmental Technologies Corporation or Romic) is a closed hazardous waste management facility located in East Palo Alto, California near San Francisco Bay. In 2007, the facility ceased operations and was demolished in 2009. All the surface structures, including distillation towers, storage tanks, and hazardous waste drum storage buildings were demolished as part of the closure process.
Romic operated the 12.6-acre facility from approximately 1964 to 2007. Historical facility operations included solvent recycling, fuel blending, wastewater treatment, and hazardous waste storage and treatment. Soil and groundwater beneath the site became contaminated as a result of Romic's past operations and those of its predecessor companies dating back to the 1950s. The primary contaminants in the soil and groundwater are volatile organic compounds (VOCs). Typical VOCs found at Romic are solvents used in the dry cleaning and automotive industries. Groundwater contamination extends across most of the site to a depth of at least 80 feet below ground surface. The groundwater is not a drinking water source.
Remedy Decision for Soil and Groundwater
Biological treatment was the primary remedy selected by EPA to address the solvent contaminated soil and groundwater. Biological treatment was tested at the former facility and was proven to be successful.
The biological treatment uses a groundwater recirculation system with horizontal injection wells and a substrate that is mostly sugar. The substrate acts as a food source for the natural bacteria that live in the subsurface. These bacteria break down the solvents into less toxic end-products. The horizontal injection wells, which are over 200 feet long, are used to deliver the substrate into the subsurface. These wells are better able to accurately target contaminated zones and can treat a larger area than standard vertical well points. Other parts of the selected remedy include excavation and removal of contaminated soils, groundwater and surface water monitoring, maintenance of the existing site cover, monitored natural attenuation, financial assurance, and land-use restrictions.
Site Cleanup and Redevelopment
EPA’s selected remedy is designed to allow for flexibility during redevelopment, such as allowing the cleanup to proceed underground at the same time construction is happening on the surface. This is possible because the horizontal injection wells and the biological treatment system can operate independently and not interfere with the redevelopment construction. Approximately 40% of the full scale biological treatment system was constructed and underwent testing in 2017. The full-scale treatment system is expected to be in operation by 2020.
EPA's approach emphasizes that closure, clean-up and reuse are complementary goals. Consideration of anticipated property reuse is an integral part of the EPA's clean-up decisions. The community of East Palo Alto may benefit from redevelopment which could generate new business for the community and additional revenues for the city, while at the same time resulting in a cleaner environment.
