Liquid Waste Certification Plan for Pacific Northwest National Laboratory

The Pacific Northwest National Laboratory (PNNL) operates a number of research and development (R and D) facilities for the U.S. Department of Energy (DOE) on the Hanford Site's 300 Area (see Figure 1). Process wastewater from these facilities is treated by the 300 Area Treated Effluent Disposal Facility (TEDF) and discharged to the Columbia River via a National Pollutant Discharge Elimination System-permitted outfall. The NPDES permit specifies limits of chemical constituents and requires proper operation and maintenance of the TEDF. To meet permit requirements, Fluor Hanford, operator of the TEDF, requires generators who discharge to the 300 Area TEDF to submit a Liquid Waste Certification Plan. This plan is the second revision to PNNL's plan
