From t h e second q u a r t e r o f 1957 u n t i l t h e t h i r d q u a r t e r o f 1971, TX-101 i n t e r m i t t e n t l y rece ived Reduct ion Ox ida t ion (REDOX) waste. Also, f rom t h e second q u a r t e r o f 1971 u n t i l t h e second q u a r t e r o f 1976, TX-101 p e r i o d i c a l l y rece ived waste water. I n t h e t h i r d q u a r t e r o f 1976, t h e waste was c l a s s i f i e d as evaporator feed. I n t h e f i r s t q u a r t e r o f 1978, t h e waste was r e c l a s s i f i e d as non-complexed. From t h e t h i r d q u a r t e r o f 1979 u n t i l t h e f i r s t q u a r t e r o f 1980, t h e tank contained p a r t i a l l y n e u t r a l i z e d feed. I n t h e second q u a r t e r o f 1980, t h e waste was again c l a s s i f i e d as non-complexed. (Brev ick e t a l . 1995a). The t a n k i s sound and was l a b e l e d i n a c t i v e i n 1980.

Tank TX-101 has no t been i d e n t i f i e d as a bounding tank f o r pretreatment/ d isposal process development s t ra tegy (Kupfer e t a l . 1995). A l l tanks were p r i o r i t i z e d us ing the pretreatment s t ra tegy i n the Tank Waste Charac te r i za t i on Plan and Basis (Brown e t a l . 1995) document and a p o r t i o n o f arch ive sample ma te r ia l could be used f o r pretreatment t e s t i n g i f ava i l ab le .

2.6 HISTORICAL MODEL EVALUATION

Bounding tanks and data requirements f o r h i s t o r i c a l model evaluat ions are found i n H i s t o r i c a l Model Evaluat ion Data Requirements (Simpson and McCain 1995). Tank TX-IO1 i s no t i d e n t i f i e d as a primary bounding tank f o r h i s t o r i c a l model evaluat ions.

3.0 HOW INFORMATION WILL BE OBTAINED

The number of samples required to characterize a tank is a function of waste heterogeneity and the desired confidence to make a correct decision. directed by the safety screening DQO, if inadequate information exists to determine an appropriate number of samples, two vertical profiles will be obtained. These vertical profiles may be obtained using core, auger (for shallow tanks), or grab samples. If analysis of these profiles reveals that additional profiles are necessary to meet data needs, more sample profiles will be requested. Prior to rotary sampling it is necessary to vapor sample the tank per the requirements of Rotary Core Vapor Sampling Data Quality Objective (Price 1994).
