# GENERAL

# 

# This revision covers the years FY2005 through FY2025 -- the year the EM missions ends. All costs are in unescalated, direct FY2005 dollars. Site Overhead and Essential Site Services are not included.

# 

# Storage -- This function represents both the receipt and year-end storage of waste. Therefore, total costs from the baseline are divided by the total cubic meters received along with the year ending storage totals for each waste stream. Volumes are from the latest SWD Waste Algorithm.

The model is set to the preferred options for the different waste
streams.

# Mixed Waste

The various pretreatment and treatment rates have been provided by Leroy
Williams (with assistance from Regina Harvey) except where otherwise
noted.

MW Storage is based on total cost for MW Storage Facility Base Ops
(including E-14 Sampling Program) divided by total new waste (1,665.8
m3) plus total end of year treated and untreated storage volumes
(2,198.7 m3), or \$15,416,475 / 3,864.5 m3 = \$3,989/m3.

MLLW6 -- ETP costs escalated two years from 2002 System Plan revision
ETF costs = \$182.64\*1.04\*1.04 = \$197.54.

MLLW18 -- No storage, treatment, or disposal costs are included in the
cost model in this revision.

# Hazardous Waste

HW Treatment & Disposal is based on total cost for HW Newly Generated
and Legacy Waste (13,506,837) divided by total volume (9,212.2 m3) =
\$1,466/m3. This is an average that includes both low volume / high cost
and high volume / low cost waste streams.

HW Storage is based on total cost for HW Storage Facility Base Ops
divided by total new waste (9,134.5 m3) plus total end of year storage
volumes (30 m3), or \$6,892,818 / 9,164.5 m3 = \$752/m3. This is an
average that includes a large amount of ER waste that likely won't pass
through the N-Area gates.

# Low Level Waste

LLW Storage is based on total cost for LLW Storage Facility Base Ops
divided by total new waste (391,649 m3) plus total end of year storage
volumes (113 m3), or \$10,136,578 / 391,762 m3 = \$26 /m3.

Engineered Trench -- Costs are based on the Engineered vs. Slit Trench
Cost Comparison from 2002, and includes excavation, operations, and
backfill. Engineering costs have been added back in from the first draft
of this study. This includes the fact that a new ET will be built at
some point before FY2025. Estimated cost was \$42.18/m3, but is
escalated two years at 4% to \$45.62/m3.

Slit Trench -- Costs are based on the Engineered vs. Slit Trench Cost
Comparison from 2002, and includes excavation, operations, and backfill.
Engineering costs have been added back in from the first draft of this
study. Estimated cost for containerized waste was \$87.82/m3, but is
escalated two years at 4% \$94.99/m3. Uncontainerized waste was assumed
to have no sacrificial rigging costs, and 90% of all other containerized
waste operations costs, or \$63.18/m3, but is escalated two years at 4%
\$68.34.

LAW Vault -- Operating costs for disposal assumed to be the same for LAW
and ILV. The plan assumes the construction of no new sets of vaults.
9,062 m3 of waste will be disposed in the LAWV per the baseline between
FY2005-FY2025 for a total cost of \$9,156,473, or \$1,010/m3. These
costs include grouting of filled cells.

ILV -- Operating costs for disposal assumed to be the same for LAW and
ILV. Assumes construction of no new sets of vaults -- neither the silo
cell nor the bulk cells will be filled to capacity by the end of FY2025.
9,062 m3 of waste will be disposed in the LAWV per the baseline between
FY2005-FY2025 for a total cost of \$9,156,473, or \$1,010/m3. These
costs include grouting of filled cells.

Components in Grout -- Per memo to Shawn Reed dated 10/16/2002, cost per
ft3 is \$9.92 or \$350/m3. This is based on the Bulk Boxes job which was
completed in September, 2002. Baseline costs and volumes for
FY2004-FY2008, however, show \$2,832/m3. Experience has shown a wide
array for costs due to various efficiencies and configurations.
Therefore, this cost model assumes a middle value of \$1,500/m3, while
acknowledging that individual CiG jobs could be either greatly higher or
lower. With most recent costs and volume data with experience with
larger volumes, however, this revision uses a lower value of \$415/m3.

Disposal at NTS -- Per Leroy Williams 11/20/2003, \$201/m3 for
transportation + \$232/m3 disposal. Per Leroy Williams 11/18/2004,
escalate by 4% for the 2004 System Plan revision, or \$450/m3.

Disposal at Envirocare (Facility A) -- Per Leroy Williams 11/20/2003,
\$201/m3 for transportation + \$520/m3 disposal. Per Leroy Williams
11/18/2004, escalate by 4% for the 2004 System Plan revision, or
\$750/m3.

Disposal at Barnwell (Facility C) - Per Leroy Williams 11/20/2003,
\$3/m3 for transportation + \$14,000/m3 disposal. Per Leroy Williams
11/18/2004, escalate by 4% for the 2004 System Plan revision, or
\$14,563/m3.

Survey/Decon -- \$452/m3 from prior System Plan revisions, escalated two
years at 4% to \$488.88/m3.

Size Reduction - \$2,853/m3 from prior System Plan revisions, escalated
two years at 4% to \$3,085.80/m3.

Commercial Stabilization B -- Per rate sheet, \$7,900/m3 to stabilize +
\$200/m3 transporation. Escalated one year by 4% to \$13,749/m3.

Commercial Stabilization U -- Per rate sheet, \$13,200/m3 to stabilize +
\$20/m3 transportation. Escalated one year by 4% to \$8,424/m3.

Commercial Stabilization O -- Per rate sheet, \$15,900/m3 to stabilize +
\$200/m3 transportation. Escalated one year by 4% to \$16,744/m3.

Commercial Incineration U (Permafix/DSSI) -- Per rate sheet, \$21,100/m3
to incinerate + \$20/m3 transportation. Escalated one year by 4% to
\$21,965/m3.

DOE/TSCA Incineration -- Per rate sheet, \$20/m3 transportation to Oak
Ridge, disposal free. Escalated one year by 4% to \$21/m3.

In Place Disposal -- From prior System Plan revisions. \$494/m3 in 2002
revision, two years by 4% to \$534.31/m3.

TBD Treatment -- \$7,500/m3 from prior System Plan revisions, escalated
two years by 4% to \$8,112/m3.

LLW1 -- Waste is assumed to be packaged. Slit trench costed at
containerized rate. Model assumes all waste goes to one disposal
facility, though in reality the waste will likely be split among several
of the options.

LLW5 -- For Option B, transportation to NTS + \$88. For Option C,
transportation to SRS Slit Trench + \$20. For Option D, transportation
to NTS + \$264. For Option E, transportation to SRS Engineered Trench +
\$20. For Option F, transportation to NTS + \$264. For incineration
options, assume a greater than 100:1 volume reduction ratio, and
therefore no (or negligible) disposal cost. Set model to Option A in
lieu of a designated preferred option.

LLW7 -- Slit Trench disposal is assumed to be containerized. Size
Reduction assumed to have a 3:1 volume reduction factor.

LLW8 -- Assume Slit Trench waste is uncontainerized.

LLW10 -- Assume Slit Trench waste is containerized.

LLW11 -- Assume Slit Trench waste is containerized.

LLW12 -- Assume Slit Trench waste is containerized.

LLW13 -- ETF rate \$182.64/m3 per John Simpson 10/31/2002, escalated two
years at 4% to \$188.12/m3. No storage costs assumed associated with
this waste stream.

# TRU Waste

The difficulty in preparing the TRU Waste Section for this year's System
Plan revision was in matching the SRS Waste group numbers (SRS-TRU-2,
SRS-TRU-3, etc.) with the volumes in the SWB baseline. For Low Activity
/ Drummed TRU Waste, SRS-TRU-2, SRS-TRU-3, and SRS-TRU-4 were assumed to
match that work scope. For the High Activity / Non-Drummed TRU Waste,
SRS-TRU-5 through SRS-TRU-10 were assumed to match the work scope. Given
that the preferred options are already known, only the preferred options
are costed. All other options are either uncosted or assumed to still
match their \$/M3 values from prior system plan revisions. Given that
the HA TRU program baseline still remains a "work in progress," several
"broad brush" assumptions were made in putting together the cost model.
All major assumptions are listed below.

TRU Storage is based on total cost for TRU Storage Facility Base Ops
divided by total legacy and new waste (6,350 m3) plus total end of year
storage volumes (26,173 m3), or \$16,585,550 / 32,523 m3 = \$510 /m3.

**Low Activity TRU Waste** -- Under the new contract, the LA TRU program
(legacy) will continue from FY2005 through FY2006, after which all new
waste will be classified as HA TRU waste. Total direct cost for LA TRU
FY2004-FY2006 is \$47,162,369 per the SWD baseline. Total volumes are
assumed to the current inventory (legacy) totals for SRS-TRU-2,
SRS-TRU-3, and SRS-TRU-4. These costs were divided into three sections:
Characterization, Remediation, Loading and Shipping, and Support.
Furthermore, the Support costs were prorated over the other three scope
categories in order to arrive at all inclusive unit rates. These cost
elements included:

> Characterization -- NDE Prescreening, NDA Prescreening, Mining and
> Handling, Culvert Retrieval, Pad 4 Drum Handling, Vent and Purge, and
> Visual Examination
>
> Remediation -- Glovebag Remediation, Glovebox Redediation, LANL
> Remediation, and Miscellaneous Remedition

Loading and Shipping -- Pad 3 Loading and Shipping

Support -- Ship to WIPP Support and Ship to WIPP Projects

The final unit rates were Characterization \$5,456/m3, Remediation
\$4,943/m3, and Loading and Shipping \$4,856/m3. Note: all fixed capital
costs have been made variable within these unit rates. The total cost
per m3 is approximately 4% higher than the 2003 System Plan estimates.

**New Generated Waste** -- All waste in the "forecast" column is
classified as "Newly Generated" waste. Though technically under the HA
Program, this waste will cover what is currently legacy LA and legacy
HA. With all of the GFSI HA characterization in place, one production
line for relatively small volumes is forecast. The costs are calculated
in a manner similar to the LA TRU Waste streams. The final unit rates
were Characterization \$7,865m3, Remediation \$2,562/m3, and Loading and
Shipping \$3,859/m3. Note: all fixed capital costs have been made
variable within these unit rates. Though the cost distribution is
somewhat different from the LA estimates, the final bottom line is
similar. Note that these costs are highly speculative.

**High Activity TRU Waste** -- As stated earlier, the major challenge
was to correlate the SWD Baseline scope with the System Plan disposition
options. The overall methodology was to determine the \$/m3 for the SWD
Baseline scope, and then crosswalk these \$/m3 as closely as possible to
the disposition options. Note that all newly generated waste in the
forecast is covered by the Newly Generated waste rates above.

The main issue, however, is the lack of correlation between the various
systems tracking current HA TRU Waste inventory. The disposition options
show 4,632 m3, Steve Mentrup shows me 4,616 m3, and a mathematical count
of the volumes of containers shows 5,026. Furthermore, two of the
different counts neglect to show the volumes for the "HA Drums" and "New
Mound" waste that is budgeted.

The only reasonable solution, without arbitrarily making up numbers, is
to come up with a total consolidated HA TRU budget and divide it by the
total volume. With the information at hand, any other values would be
subject to massive questioning. Costs are based on the FY2007-FY2010
exercise that predates the current baseline. This is because the current
(December 2004) baseline overstates the HA budget, and a revision is
still being worked on.

For SRS-TRU-5 through SRS-TRU-10, therefore, the cost per cubic meter is
\$49,884,868 divided by 4,632.3 m3, or \$10,769/m3. Note that these
costs are likely low, and will probably be closer to the New Generated
Waste costs per m3 once the revised baseline is completed.

It should be recognized that there should really be a wider range among
the options, from \~\$57K/m3 for MSMS (due to small volume) to \~\$4K
for Polyboxes, with the bulk of the waste, Black Boxes, at \~\$8/m3.
Once better volumes figures and crosswalks are made available then this
section of the System Plan should be revisited.
