The Double-Shell Tank (DST) System began operations between November 1955 and October 1986 (refer to the Tank Table on pages
3 and 4). The DST System is used for the interim storage (S02) of liquid mixed waste generated on the Hanford Facility.
Several operating Units in the 200 East and 200 West Areas transfer liquid nixed waste through buried dcubte-encased transfer
Lima to designated underground DSTs. Other types of liquid mixed waste in the DST System are received from railroad tank
car transfers, tank truck transfers, the Single-shell Tank (SST) System, and smeller temporary storage tanks.
Pretreatment will be performed as necessary at a future Unit and/or at the 242-A Evaporator. The low-level liquid mixed
waste is accumulated in the DST System until the waste is transferred for treatment to a proposed low-level vitrification
plant in preparation'for final disposal. The high-level liquid mixed waste from the DST System could be treated at the
propose! Hanford Waste Vitrification Plant CHWVP) and shipped to a natfonal reposito ry for disposal- The NUVp could be
superseded by another high-level waste fnmobilizetlon facility.
The tanks in the DST System are considered treatment Units (TOI) because chemicals can be added for corrosion c on trol, the
waste can be mixed using equipment such as airlift circulators or punpa, and water can be evaporated from the aging waste
tanks by adding heat.
The tanks in the DST Systemare shown on the Tank Table (pages 3 and 4), which includes tank numbers, locations, design
capacities, and operational dates. The specific TSD Snit boundaries will be defined in the DST System Dangerous Waste
Part B permit application documentati on .
The maximum process design capacity for tank storage at the DST System is approximately 124,654,500 liters
(32,930 0 230 gallons). The maximum process design capacity for tank treatment at the DST System is approximately
124,654,500 liters (32,930,230 gallons).
IV. DESCRIPTION OF DANGEROUS WASTES
A. DANGEROUS WASTE NUMBER - Enter the four digit number fr om Chapter 173.303 WAC for each listed dange ro us me* you will handle. If you handle
dange ro us wastes which am not riled M Chapter 173-303 WA C. enter the tow dig it number(s) that des cribe. the chara ct eristi cs and/er the toxic con.
remnant. of those dange rous wastes.
B. ESTIMATED ANNUAL QUANTITY - For each Rated waste entered in column A estimate the qua ntity of that waste that wi ll be handled on an annu al b as is.
For adh chara ctedsti. or taxi. contaminant ente re d M column A es timate the total annual quantity of all the non-lifted wastes) th at will be handled which
peo ples that chara cteristic or contaminant.
C. UNIT OF MEASURE - For each quantity entered in column B enter the unit of measure code. Un its of measure w hich must be used and the app rop riate codes
are:

NOTE: DANGEROUS WASTES DESCRIBED BY MORE THAN ONE DANGEROUS WASTE NUMBER - Dange rous wastes that can be desc ribed by more than one Waste
Number shill be des cribed on the form as fol lows:
1. Sele ct one of the Dange rous Waste Numbers and enter It in column A. On the same line complete columns B. C, and D by estimating the total annual quantity of
the waste and describ ing al l the proasses to he used to trait, store, and/or dispels of the waste.
2. In column A of the next li ne enter the other Dange rous Watts Number that can be used to desc ri be the m ate. In column D12) on that line enter "Includ ed with
