1.  []{#__RefHeading___Toc138124400 .anchor}**Task Order Purpose and
    Overview**

    a.  This is a Cost Plus Fixed Fee task order issued under the
        Department of Energy Environmental Management's Indefinite
        Delivery Indefinite Quantity (IDIQ) Task Order Contract. This
        task order and the contract reflect the application of
        approaches and techniques that emphasize results/outcomes and
        minimize "how to" performance descriptions. The Contractor has
        the responsibility for total performance under the Task Order,
        including determining the specific methods for accomplishing the
        work.

    b.  The purpose of the Task Order is to safely remove radioactive
        materials and contamination from the OU- 1 Project Area (Figure
        -- Parcel 9) on the Miamisburg Closure Project (MCP) site to
        levels that will allow for industrial reuse in support of the
        accelerated closure of the MCP. The OU-1 selected response
        action is an excavation-based response action. The OU-1 Project
        consists of two (2) distinct projects: OU-1 Project (Figure 1 --
        Parcel 9) and Potential Release Site 441 (PRS 441) Project. The
        Contractor shall complete the necessary waste management and
        disposal of the contaminated soils, provide verification samples
        and reports, backfill of the excavation, and accomplish site
        restoration of the OU-1 Project Area to acceptable standards.

    c.  Although the OU-1 site was previously compliant with the
        requirements defined by the Comprehensive Environmental
        Response, Compensation and Liability Act (CERCLA) OU-1 Record of
        Decision (ROD), the actions taken under this task order are at
        the discretion of the Department of Energy and are additional
        remedial actions directed by the Congress of the United States
        in the 2006 House Conference Report 109-275, page 170. As part
        of the direction from Congress, DOE has been provided a \$30
        million budget to complete the project. However, the total funds
        anticipated to be available for execution of the task order are
        \$29 million. These funds are only to be used for OU-1
        remediation activities. No additional funds will be available to
        support the project or reimburse any costs incurred by the
        Contractor. Therefore, it is imperative that the Contractor only
        use the funds for OU-1 activities as defined in the SOW and this
        task order. In addition, it is imperative that the Contractor
        comply with all notification requirements in the contract,
        especially the notifications required under the Limitation of
        Funds clause.

    d.  The reuse vision for the OU-1 area is to permit the site to be
        developed without further restriction or limitation. The
        development plan for the area (as provided under the MMCIC
        Comprehensive Reuse Plan) is to construct an industrial or
        office structure on the site with its support systems (parking,
        utilities, etc.), and a public roadway. If funds are not
        sufficient to fully permit the implementation of the reuse
        vision, the DOE's goal and the Contractor's goal is to be the
        removal of wastes as prioritized in the SOW.

    e.  The OU-1 Project overall objectives/guidance for this Task Order
        are:

        i.  Not to exceed \$29M

        ii. Comply with regulatory requirements and be protective of
            human health and the environment

        iii. Meet the spirit and intent of the Sales Contract

        iv. Permit industrial reuse of the OU-1 area

        v.  Be consistent with the past cleanup practices, levels and
            objectives

        vi. Provide the most efficient use of government funds

    f.  The specific work required to be performed in order to meet
        these OU-1 Project overall objectives/guidance are set forth in
        the Statement of Work.

    g.  The primary area of concern consists of a Site Sanitary Landfill
        that sits on top of an older Historic Waste Disposal Area. The
        wastes in the Historical Waste Disposal area include radioactive
        materials and hazardous waste, and other wastes described in the
        SOW. The DOE has established the following waste removal
        priorities: 1) Thorium and Polonium Contaminated Waste Area
        (PRS-11); 2) Volatile Organic Compounds (VOCs) "Hot Spot"
        Area; 3) Other Historic Waste Area; 4) Dayton Unit Trench;
        and 5) Site Sanitary Landfill Waste.

    h.  DOE will incrementally authorize the remediation activities
        dependent on the Contractor performance and availability of
        funds.

    i.  The goal of the PRS 441 Project is to be compliant with the
        requirements defined by the Comprehensive Environmental
        Response, Compensation and Liability Act (CERCLA) as implemented
        by the Mound 2000 Work Plan and associated site cleanup
        objectives. Funding for the PRS 441 Project scope of work is
        provided separately from the funding appropriated by Congress
        for the OU-1 Project scope of work.

2.  []{#__RefHeading___Toc138124401 .anchor}**End-State**

    a.  In order to achieve Task Order completion, the following
        activities including all Task Order Statement of Work (SOW)
        requirements shall be completed by the date in Section B.4. The
        scope of these activities consists of incremental removal of the
        Site Sanitary Landfill, the identified areas of wastes in the
        Historic Waste Disposal area with radioactive wastes and high
        concentrations of solvents, and the re-grading of some of the
        surrounding soils. The scope of these activities includes the
        excavation, sampling, packaging, transporting, and disposal of
        the waste and the support activities associated with these
        activities. The End State is achieved when the following
        activities are completed:

```{=html}

            Remediation**

        ```{=html}
        <!-- -->
        ```
        a.  The following sections describe the work scope to be
            accomplished under this Task Order. The intent of the
            information contained in the subsequent sections is to
            provide the best available information on "what" work scope
            needs to be accomplished, but not to prescribe "how"
            individual work scope elements will be accomplished.

        b.  The Contractor shall maintain daily logs of the quantities
            and weight of the soils and waste being excavated, shipped,
            and/or disposed. The logs shall be used to monitor, track
            and report the quantities and weight of waste for each
            category: excavation, shipment, and/or disposal.

        c.  The data required to be obtained and maintained pertaining
            to the excavation of waste shall include field-screening
            results, field location sketches, elevations, sampling logs,
            and laboratory analytical results, including sampling and
            analysis for the waste disposal facility's waste acceptance
            criteria (WAC).

        d.  The Contractor shall be responsible for the preparing of and
            obtaining necessary approvals of the plans, permits, and
            licenses which are necessary to perform all work. This shall
            include, but not limited to, activities such as
            installing/maintaining fences and gates, silt fences,
            required signs and implementation of other controls
            necessary for health and safety of the public, workers, and
            environment. The Contractor shall be responsible for
            developing the Site Access and Traffic Control Plan for the
            OU-1 and PRS 441 projects. The Contractor shall be
            responsible for setting up work areas that are necessary in
            order to accomplish all work, including work related to
            decontamination of equipment and trailers used under this
            task order. The Contractor shall, as necessary to perform
            the work as required by the SOW, relocate/remove/install
            extraction wells and reinstall pipelines from the wells to
            the buildings.

        e.  The following sub-sections, C.2.1 and C.2.2 are listed in
            the order of excavation priority and within these sections
            the excavation priority of each type of waste or each area
            is listed. The Contractor may be required to complete
            sub-sections 2.4 and 2.5 prior to completing all work in
            sub-sections 2.1 and 2.2 to ensure the overall final cost of
            work performed does not exceed the allowable funding for the
            OU-1 Project.

            []{#__RefHeading___Toc138124405 .anchor}**2.1 Site Sanitary

            []{#__RefHeading___Toc138124406 .anchor}**2.1.1 Site
            Sanitary Landfill Waste**

        ```{=html}
        <!-- -->
        ```
        a.  The Site Sanitary Landfill wastes, based upon historic
            reports, are reported to consist primarily of office wastes,
            cafeteria wastes, some bioassay samples and soil. Although
            the wastes in the Site Sanitary Landfill are expected to be
            non hazardous, there is a possibility that it may have some
            wastes from the Historic Waste Disposal Area. Historic
            documents reflect that the wastes placed in the Site
            Sanitary Landfill were screened for plutonium-238. No
            radioactive wastes were found above the screening level (100
            pCi/g) for plutonium-238.

        b.  The Contractor shall determine the levels of contamination
            of wastes from the contaminated liner, berm and clean liner
            materials by field screening, and at the same time maintain
            and segregate radioactive and hazardous materials segregated
            until the Contractor determines the final disposition paths
            for the waste which supports maximization of performance as
            well as the least costely disposition path. The Contractor
            shall maintain stockpiled materials to prevent the spread of
            contamination and odor.

            []{#__RefHeading___Toc138124407 .anchor}**2.1.2 Site
            Sanitary Landfill Cover, Berm, Cap and Liner**

        ```{=html}
        <!-- -->
        ```
        a.  The Site Sanitary Landfill has a soil cover, cap and liner
            as shown in the "Overflow Pond" drawings on the Mound OU-1
            Project website. The berm that surrounds the wastes cell was
            constructed from soils excavated from a hill that was
            located where the current overflow pond now exists. There is
            a possibility that sediments containing low-level plutonium
            contamination placed in the Site Sanitary Landfill were also
            randomly incorporated into the Site Sanitary Landfill cap
            during construction. Mound Plant health physicists screened
            the entire Site Sanitary Landfill and Overflow Pond
            construction project (see Section J, Attachment D). One
            bucket (less than five gallons of soil) with an elevated
            plutonium concentration above 100 pCi/g was removed. Only
            material with plutonium levels greater than 100 pCi/g was
            considered hazardous during the time frame in which the Site
            Sanitary Landfill and Overflow Pond were constructed. The
            current 10^-5^ cleanup value for Pu-238 is 55 pCi/g.

        b.  The Contractor shall excavate berm material in order to
            access the Historical Waste Disposal areas. The Contractor
            shall be responsible for maintaining the berm material and
            will segregated the waste (radiological and hazardous) to
            prevent the spread of contamination and odor.

        c.  For excavation in areas above the Historic Waste Disposal
            Areas, the Contractor shall excavate in 2 foot depth
            increments, and screen, in 2 foot depth increments for Rad,
            VOCs, and visible waste or staining below the berm material
            (elevation 710). The Contractor shall excavate in 2 foot
            depth increments and screen in 2 foot depth increments, for
            Rad, VOCs, and visible waste or staining below the PRS11
            backfill material (elevation 688). For excavation in areas
            found not to be above the Historic Waste Disposal Area, the
            Contractor shall excavate down to native soil only as shown
            in the "Overflow Pond" drawings on the Mound OU-1 Project
            website and such drawings are incorporated into the SOW.

            []{#__RefHeading___Toc138124408 .anchor}**2.2 Historic
            Waste** **Disposal Area**

        ```{=html}
        <!-- -->
        ```
        a.  The Historic Waste Disposal area consists of the following,
            which are listed in the order of removal priority (See
            Figures 2 and 3):

            i.  Thorium Drum (PRS-11)Area

            ii. VOC "Hot Spot" Area

            iii. Other Historic Waste (Remaining Historic Landfill Area)

            iv. Dayton Unit Trench

                []{#__RefHeading___Toc138124409 .anchor}**2.2.1 Thorium
                Drum Area (PRS-11)**

        ```{=html}
        <!-- -->
        ```
        a.  In the 1950s approximately 2500 empty 55-gallon drums
            contaminated with thorium were crushed and buried in a
            trench in the southwest corner of OU-1. As part of a
            separate disposal operation in 1965, sand contaminated with
            polonium-210 (a residual product of the polonium research
            and production conducted in the early 1950s) was also placed
            in the trench. This Thorium and Polonium Contaminated Waste
            Area is now known as Potential Release Site 11 (PRS-11).
            Subsequent activities smeared some of the material ("smear
            zone") in the trench across areas of the Historic Waste
            Disposal Area. During the summer of 2005, a portion of the
            crushed thorium drums from within the Historic Waste
            Disposal Area was removed from the southwest corner of the
            OU-1 area. Other waste that was found and excavated included
            the following: wood, brick, glass, laboratory bottles,
            sealed intact bottles with solvents and mercury, an I-beam,
            a utility pole, a tank, personal protective clothing,
            mercury contaminated material, solvent contaminated
            material, material contaminated with plutonium-238,
            uranium-238, radium-226, lead-210 and thorium-232. The area
            was subsequently backfilled with clean soil. Available as a
            reference document only is the PRS-11 On-Scene Coordinator's
            (OSC) Report.

        b.  The Contractor shall excavate PRS-11 and the smear zone. The
            Contractor will package, transport/ship, and dispose of the
            waste and material from PRS-11 and the smear zone.

            []{#__RefHeading___Toc138124410 .anchor}**2.2.2 Volatile
            Organic Compounds (VOCs) "Hot Spot" Area**

        ```{=html}
        <!-- -->
        ```
        a.  The Mound Plant began a sampling program for VOCs in 1984,
            and initiated extensive surface and subsurface soil and
            ground water investigations in 1987. In 1989, the Mound site
            was placed on the U.S. Environmental Protection Agency's
            (EPA) National Priority List (NPL) as a result of the VOCs
            in ground water that were first detected in 1986 and have
            been monitored ever since. The OU-1 area was determined to
            be the source of some of the VOC contamination. Based on the
            analyses of samples collected from sample boring at OU-1,
            there is a "hot spot" with soil and wastes contaminated with
            high concentrations of VOCs in the Historic Waste Disposal
            Area. In June 1995, a CERCLA Record of Decision (ROD) for
            OU-1 was signed by the U.S. Department of Energy, the U.S.
            EPA and the Ohio EPA. This ROD selected a remedy, a ground
            water pump-and-treat system, to collect, treat, and dispose
            of ground water contaminated with VOCs. The ground water
            pump-and-treat system was installed in 1996. Shortly
            thereafter the DOE installed a Soil Vapor Extraction (SVE)
            system to treat VOC contamination in the vadose
            (unsaturated) zone and mitigate the continued migration of
            VOC contaminants to ground water. To date, the SVE system
            has removed approximately 4,000 pounds of VOCs. The SVE
            monitoring wells in the southwest quadrant of the OU-1 site
            have detected VOC contaminants from an area just to the
            North of the extraction wells. This area is considered a
            "Hot Spot" source of VOCs.

        b.  The Contractor shall excavate the VOC Hot Spot Area,
            including all waste and soils below the PRS-11 Area that is
            and will have been excavated (Section 2.2.1). The Contractor
            shall package, transport/ship, and dispose of the all
            material and waste.

        a.  The remainder of the historic waste disposal area contains a
            variety of wastes, including ordinary laboratory, office and
            kitchen wastes, along with sediments containing metals
            (beryllium and mercury), plating wastes, oils and
            chlorinated and non-chlorinated solvents. Materials expected
            to be found in the remainder of the Historic Waste Disposal
            Area are likely to be similar to those found during the
            PRS-11 excavation. The Contractor shall excavate, package,
            transport/ship, and dispose of the Other Historic Waste in
            the following areas (see Figure 4 geographical areas) in the
            following order:

                Area:]{.underline} Extends from the south side of the
                dike around the overflow pond to the south side of the
                B2 area. The top of the excavation on the west side of
                the excavation is to be no closer than four feet east of
                the road pavement and is to have a safe and stable
                layback slope that is sufficient to support the road.

            ii. [Below the Road]{.underline}: Extends from the
                intersection north to the dike on the south side of the
                overflow pond and westward under the road from the
                previous excavation area (in Section 2.2.3 (a)(i)). An
                alternate traffic access for the public or lessees of
                the MMCIC may be necessary and the Contractor is
                required to ensure that the public and lessees have an
                alternate route of access.

            iii. [Northern end of Historic Waste Disposal

        ```
        a.  In 1954, salvage material from several buildings in Dayton,
            Ohio used for research purposes (Dayton Unit trench) was
            disposed in an excavated trench along the southern boundary
            of the OU-1 area. This Unit lies below the PRS 11 and may
            extend below the water table (elevation 680.5). The Dayton
            Unit trench contains buried wood ash and debris from a fire
            that had consumed the polonium-contaminated flooring from
            the Dayton Units. Number range CHAPTERSince polonium-210 has
            a half-life of 138 days, it is not expected to be present as
            a contaminant unless radiological parent material is
            present. Lead-210 (half-life of 22 years) may have been used
            in one of the processes to produce polonium-210 (a daughter
            of lead-210) and may be present in the trench, decaying to
            polonium-210. Bismuth-210 may also be present as a trace
            contaminant.

        b.  The Contractor shall excavate all of the material/waste
            until the Mound Cleanup Value Table (Table-1), as well as
            the values in Section 2.4 are achieved. The Contractor shall
            not excavate beyond the ground water table. The contractor
            shall package, transport/ship, and dispose of all
            waste/material. In the event the Contractor cannot achieve
            the Mound Cleanup Values identified above without excavating
            beyond the ground water table, the Contractor shall notify
            the Contracting Officer immediately.

            PRS 441 -- Soil Staging Area**

        ```{=html}
        <!-- -->
        ```
        a.  PRS 441 is the Soil Staging Area and Expansion Area located
            near the rail spur, north of the Overflow Pond. This area
            has been used for the staging and loading of contaminated
            soils and debris awaiting shipment off-site.

        b.  To enable continued use of the rail spur, this area can be
            one of the last areas to be remediated by the Contractor.
            Funding for the PRS 441 Project is separate and apart from
            the \$29 million funding for OU-1 Project and is outside of
            the \$30 million appropriated for the project. The rail spur
            is operational and available for use. PRS 441 was binned a
            removal action on March 1, 2005; however, the data package
            has not been signed or sent for public comment.

        c.  The Contractor shall remediate and verify the soil staging
            area (PRS 441) in accordance with and consistent with the
            Mound 2000 Response Action Process outlined in the Work Plan
            for Environmental Restoration of the DOE Mound Site, The
            Mound 2000 Approach, Final, February 1999. The Contractor
            shall remove the railroad tracks and excavate the
            contaminated soils and pavement, if determined to be
            necessary under the above Mound 2000 Approach, and conduct
            Final Verification Survey (FVS). All supporting
            infrastructure and Government Furnished Services Items
            (GFSI) shall also be disposed of by the Contractor. All cost
            associated with the PRS 441 Project, including section 2.4
            and 2.5 shall be allocated to CLIN006.

        d.  The Contractor shall excavate, package, transport/ship, and
            dispose of all waste from the remediation of PRS-441.

            Verification Survey**

        ```{=html}
        <!-- -->
        ```
        a.  The Contractor shall conduct a Final Verification Survey in
            the PRS 441 area and all of the OU-1 areas. Backfilling and
            regrading in the OU-1 area (section 2.5.1) shall be
            performed prior to the Final Verification Survey. Any
            additional contaminated spot discovered during backfilling
            and regrading shall be removed prior to the Final
            Verification Survey. Final Verification Surveys shall be
            conducted using a plan approved by Ohio and USEPA.

        b.  The Contractor shall collect all Final Verification Samples
            to a depth of known waste or un-sampled soil and analyze per
            SAAP. The Mound Cleanup Values for a carcinogen is 10E5
            calculated excess cancer risk under a site office worker and
            construction worker scenario as described in the Mound 2000
            Residual Risk Evaluation Methodology document (Final,
            January 1997). For non-carcinogens, a hazard index of less
            than one is targeted.

        c.  The Contractor shall provide documentation of the OU-1 end
            state as well as any and all documentation to support a
            draft OU-1 ROD Amendment.

            Restoration**

        ```{=html}
        <!-- -->
        ```
        a.  The Contractor shall leave the site in a manner that is at
            least as protective of human health and the environment as
            before the OU-1 project remediation (this task order) which
            is compliant with the requirements defined by the
            Comprehensive Environmental Response, Compensation and
            Liability Act (CERCLA) OU-1 ROD. In addition to any other
            requirements of the SOW, including, but not limited to,
            disposal of the Site Sanitary Landfill wastes either on-site
            or off-site and covering in an appropriate manner, this task
            order requires compliance with any and all regulatory,
            federal, state, and local requirements regarding any wastes
            that are not removed from the site, backfilling, grading,
            and seeding in all disturbed areas.

        b.  If the Contractor determines that the Site Sanitary Landfill
            waste can appropriately and properly be disposed on-site,
            the Contractor shall place the waste within a compacted clay
            liner similar to that of the existing Site Sanitary
            Landfill. The Contractor shall load and transport the waste
            to the location, and cover the cap with two (2) feet of soil
            and mark with geofabric.

            **2.5.1 Final Grading, Seeding and Extraneous Debris
            Removal**

        ```{=html}
        <!-- -->
        ```
        a.  Upon completion of the excavation, the Contractor shall
            prepare the disturbed area(s) for reuse by grading, seeding
            and removing debris from all of the areas. These areas shall
            include PRS 441 and the OU-1 disturbed areas, and the
            staging area. The contractor shall provide a grading plan in
            the Site Specific Excavation Plan for the excess soils and
            disturbed areas.

        b.  For the Contractor's information only, reuse of the OU-1
            area has been broken down into the sub-areas (see Figure 5),
            defined as follows:

            1.  (Sub-area A): transition from the proposed roadway
                (Vanguard Boulevard) to the buildable area

            2.  (Sub-area B): the buildable area, which includes the
                building pads and parking areas

            3.  (Sub-area C): the transition area from the buildable
                area back into natural topography

        c.  For the Contractor's information only, the slopes for
            sub-area A from the back of the proposed sidewalk to the
            finished grade for the building pad (proposed for each lot)
            should be a maximum of 3:1 with a preferred of 4:1 or less.
            The slopes for sub-area C should be similar to sub-area A.
            Depending on the volume of waste removed and berm material
            available, the desire is to provide a finished grade for
            each proposed building pad to have a minimum of eight feet
            (six feet above geo-fabric and the two (2) foot soil cover
            that is required for any waste remaining on site). The
            proposed elevation for the building pads is approximately
            719 feet. Building pad(s) including an area for parking lots
            should be leveled (2% slope, max.) for drainage.

        d.  Given the above information (Section 2.5.1(b),(c)), if
            enough excess soil is not available to fill the areas in
            order to achieve the preferred requirement and grades, the
            Contractor shall consult with DOE for a determination
            regarding the priority of the areas for use of the preferred
            requirement and shall develop the grading plan accordingly.
            Excess berm soils shall only be used to backfill the
            Historic Waste Disposal Area. The Contractor shall grade the
            OU-1 Project area in a manner that provides uniform slopes
            as well as positive drainage.

        e.  If the Contractor determines and DOE approves that a storm
            water retention/detention basin for the Historic Waste
            Disposal Area is necessary, the Contractor shall construct a
            storm water retention/detention basin. The basin shall begin
            no less than ten (10) feet from the back of the proposed
            sidewalk in Figure 5. In addition, the basin should be
            constructed as a retention and detention basin that complies
            with and meets the Montgomery County, Ohio regulations for
            storm water detention. The approximate storm water detention
            volume required is 538,200 cubic feet.

        f.  For areas that are backfilled or disturbed, the top 6" shall
            be free of stones or foreign materials larger than 1".
            Seeding and mulching shall be per Ohio Department of
            Transportation Specification 659, or approved equal.

        g.  For backfilling, the Contractor shall install the material
            in maximum of 8" to 12" lifts unless deviations are approved
            by DOE. Backfill shall be compacted to meet reuse
            requirements (85% Standard Procter (SP) for landscaped
            areas, 92% SP for parking or building areas, and 95% SP for
            roadways).
