Summary This report describes the analytical results of vapor samples taken from the headspace of the waste storage tank 241-BY-102 (Tank BY-102) at the Hanford Site in Washington State. The results described in this report were obtained to characterize the vapors present in the tank headspace and to support safety evaluations and tank farm operations. The results include air concentrations of selected inorganic and organic analytes and grouped compounds from samples obtained by Westinghouse Hanford Company (WHC) and provided for analysis to Pacific Northwest National Laboratory (FWNL). Analyses were performed by the Vapor Analytical Laboratory (VAL) at PNNL. Analyte concentrations were based on analytical results and, where appropriate, on sample volumes provided by WHC. A summary of the inorganic analytes, permanent gases, and total non-methane hydrocarbons is listed in Table S.1. Detailed descriptions of the analytical results appear in the text. 15.3 rfr 0.6 Permanent Gases SUMMAm Canister COZ 24 J co 3 u CH, 4 u H2 34 N20 18 J Total Non-Methane SUMMA" Canister Hydrocarbons 19.87 Hydrocarbons (TO-12) mg/m3 (a) (b) Vapor concentrations were determined using sample-volume data provided by Westinghouse Hanford Company and are based on averaged data. Inorganic analyte concentrations are based on dry tank air at standard temperature and pressure. Data Qualifier Flags Target compound detected above the Instrument Detection Limit (IDL) but below Estimated Quantitation Limit (EQL). Target compound not detected at or above the IDL.
