nonprocessable material will be combined with dried waste in the railcars. The following
sections detail the various waste handling and blending procedures.
During excavation, waste materials within the pit will be segregated into three categories:
Nontypical waste
0 Nonprocessable waste
0 Processable waste.
Nontypical waste that does not meet the CDF WAC or cannot be treated to meet the CDF WAC
will be stockpiled in the excavation areas and managed until the material is turned over to FDF
for disposal. IT will transport the nontypical material to a designated area between Waste Pits 4
and 6, along the existing roadway, where the material can be containerized, transferred to FDF,
and loaded into trucks outside the radiologically controlled area.
Nonprocessable waste is waste material that meets the CDF WAC but cannot be fed into the
dryer. This type of waste may consist of debris that could not pass through a 4-inch screen such
as rocks, wood, clumps of clay, etc. To the extent possible, nonprocessable waste will be
segregated in the excavation areas and transported to the Material Handling Building separately.
Processable waste from a single source will be blended in the excavation, primarily on the basis
of moisture content, to achieve a manageable material.
When excavated, wastes will be classified as low WAC or high WAC material, depending on the
levels of radioactive constituents and other pertinent processingldisposal criteria. Historical
surveys and investigations of each pit, the trend analysis from ongoing monitoring, and chemical 26
analysis of waste materials as the remediation proceeds, will allow segregation of waste materials 27
based on the levels of radioactive constituents. Wastes will be loaded into contained dump 28
trucks (approximate 2 1 -yard capacity) and transported from the pit area over the designated haul 29
road to the Material Handling Building. Three trucks are expected to be making the continuous 30
route at any given time, at an average rate of three trucks per hour up to a maximum rate of six 31
trucks per hour. 32

Additional waste blqding will occur in the Material Handling Building and Railcar Loadout 34
Building. The blending of material from more than one source will occur in the mixing pits, 35
located along the west side of the Material Handling Building. The blend ratios will be
