In January 1988, the California Regional Water Quality Control Board and the City of Livermore requested that the Lawrence Livermore National Laboratory (LLNL) make provisions to ensure that effluent releases to the City of Livermore sewer system are in accordance with the LLNL Wastewater Discharge Permit. The primary purpose of the Sewer Diversion Facility (SDF) is to divert sewage that contains constituents that are above alarm levels. Diverted sewage from LLNL and Sandia National Laboratories, Livermore (SNL, Livermore) is pumped to holding tanks for analyses, approved treatment and release, or disposal. LLNL and SNL, Livermore have management plans to control wastewater discharges into the sanitary sewer system. This minimizes the possibility that diverted sewage could have characteristics requiring it to be classified as hazardous waste. However, hazardous waste storage tank regulations have been applied as a best management practice in the event that wastewater with hazardous characteristics is diverted to the SDF storage tanks. This Engineering Evaluation of the Sewer Diversion Facility includes a description of the facility, an outline of the design standards to which the facility was built, and an evaluation of the system compared to the hazardous waste storage tank regulations. This Engineering Evaluation reflects design conditions at the time LLNL assumed beneficial occupancy of the facility. Design or operational changes may be implemented in the future as specified by LLNL.
