-INTRODUCTION 1.1 Purpose and Objectives 4
The purpose of. this report is to provide a description of the
. redress plan and the conceptual alternative developed by the CRBRP Project and TVA.
In December 1983, the CRBRP Project Director established a Redress Planning Task Force to initiate the planning effort for site ~ redress activities.
The conclusions from this planning task force were used as a starting point for the work completed by the Project presented in this report.
The objectives of the Project evaluation are as follows:
A.-
Develop-a plan to redress the site in accordance with
-NRC requirements or, in lieu of such specific i-
-requirements, in a manner determined by DOE and TVA to account for the site's potential industrial use wherever feasible.
B.
Identify and ~ account for environmental requirements that
- must be met in developing the final site redress plan.
C.-
-Include the preferred preliminary conceptual alternative l
provided by the Redress-Planning Task Force as an input in~ the development of the final redress plan.
D.
Obtain local input from the City of Oak Ridge, Roane County, and other local community leaders.
E.
Finalize the site redress plan incorporating input from other' organizations and the local community that achieves an appropriate balance between environmental requirements and concerns and physical land characteristics consistent with the potential for industrial use.

2.0 SITE HISTORY AND DESCRIPTION -
2.1 Project Status The Applicants in this proceeding are the United States Department of Energy (DOE), Project Management Corporation (PMC),
and the. Tennessee ; Valley Authority (TVA).
The Clinch River BreedercReactor Plant (CRBRP) was intended to be a Liquid Metal Fast Breeder Reactor (LMFBR) demonstration plant with a rated output-of approximately 350 megawatts of net electrical power, E
proposed to:be lo'cated on the Clinch River in Oak Ridge, Tennessee.- The land on which the site is located has previously been dedicated-to' industrial use.
~
4 On January 11, 1982, the Applicants filed a motion to lift the suspension of licensing hearings, which the Atomic Safety and Licensing Board granted.
The Board entered an Order on February 1*,1982, establishing a schedule for the commencement of evidentiary hearings concerning LWA matters.
Site suitability hearings were conducted August 23-27, 1982.
The ASLB then reopened discovery on all environmental issues, and conducted environmental hearings November 16-19, 1982, and December 13-17, 1982.
The ASLB Partial Initial Decision was published February 28, 1983.
The NRC granted a Limited Work Authorization on May 19, 1983. The CRBRP Project had previously been granted authori-
.zation to conduct site preparation activities under 10 CFR 50.12 on August 17, 1982, and actual on-site construction commenced September 22, 1982.
The U.S.
Senate voted on October 26, 1983, to table its Appropriations Committee amendment containing a multi-year appropriation for the CRBRP.
The result of this action was to provide no Fiscal Year 1984 funds necessary to continue construction of the CRBRP.1 The Applicants then concluded that there appeared no substantial likelihood that such funds will be appropriated.
As a result, the Clinch River Breeder Reactor Plant Project has been terminated and the plant will not be built.
2.2 Site Historv l
The CRBRP site -is located on a peninsula formed by the Clinch River approximately two miles upstream of the Highway 58 crossing of the river (Gallaher Bridge) within the city limits of Oak Ridge, and in Roane County, Tennessee.
The site is on a 1,346 t
acre tract of land owned by the Federal Government in the custody of TVA.
The site area is typical East Tennessee ridges and valleys.
TVA granted a right of entry in August 1982 to DOE-CRBRP to about 600 acres of the tract to begin site preparation activities authorized by the Nuclear Regulatory Commission (NRC).,
l The Constructor for the CRBRP, Stone & Webster Engineering Corporation (SKEC), started site preparation and excavation work in Septe.mber 1982.
Work authorized by the NRC included:
Excavation and backfill 1
129 Cono. Rec. S14611-S14644 (October 26, 1983).
Congress completed action on the Fiscal Year 1984 Supplemental Appropriations Bill on November 18, 1983 (129 Cona. Rec.
H10529, Nov. 18,1983).
See also 129 Cong. Rec. H9 875 (Nov.
15, 1983) and 129 Cong. Rec. S165 8 8 ( Nov. 17, 19 83 ).
i
5 Non-safety related permanent improvemente including a site access road, railroad spur to site, barge unloading facility, sewage treatment plant, and water line Construction support facilities including roads, parking areas, quarry, buildings, fire protection system, electric power, and concrete batch plant.
Site preparation and excavation and the start of the construction support facilities were curtailed on October 28, 1983.
During
-the thirteen months of work, the following was accomplished:
About '240 acres of the site were cleared and grubbed.
This includes not only the main plant area and contiguous laydown areas but also the access road, areas for spoil, and a portion of the remote quarry area.
About 1.5 million cubic yards of overburden were excavated.. The overburden, a cohesive soil, were placed in structural fill, designated random fill, or was spoiled due to organic content, high moisture content or other unsuitable conditions.
l About 1.5 million cubic yards of rock were excavated in the Nuclear Island (NI) excavation and from two main ridges.
Most of'the rock (limestone and siltstone) was crushed to a three inch maximum size and placed in Class 13 structural fills.
The permanent access road was completed through the top of subgrade.
Subsequent to curtailment of construction, twelve inches of crushed liestone aggregate was placed on the access road to provide an all-weather surface for continuing access to the site.
The on-site portion of the railrotd embankment, contiguous to the access road, was completed.
An eight-inch water line from DOE'.s Bear Creek Filtration Plant off-site was completed to road station l
50+00 (approximately 6450 feet).
A construction power substation was completed by TVA
+
taking power from the Ft. Loudon - K31 161 KV transmission line and providing 25 MVA of 13.8 KV power.
Approximately 2,000 feet of underground distribution to two construction substations was completed.
Four pre-engineered metal buildings from 4,000-5,000 square feet were erected.
A concrete ringer crane pad, approximately 80 feet by 80 feet, was constructed on the east side of the NI excavation at elevation 814.

2.2 Site'Descrintion The site includes an all-weather access road of approximately '
6500 feet from a public road (Bear Creek Road) to the plant area" a.nd-the following relatively level, stabilized areas:
The craf t parking lot at average elevation of 836 (14 acres)
~
Plant and laydown areas at average elevation of 810 (20

acres)
,.. e Other level areas at lower elevations (10 acres)
Within and contiguous to the plant area are the Nuclear Island (NI) excavation, the normal cooling tower (NCT) excavation and' the emergency cooling tower (ECT) excavation which, with their side slopes projected to plant area elevations of 810,-total 24 acres.. See attached Sketch 1.
Non-topographic features of the site, besides the all ' weather '
access road, include the 8-inch water line to road station 50+00'l approximately 2000 feet of underground power distribution, four pre-engineered. metal buildings, concrete batch plant, construc-tion power substation, and the concrete ringer crane. pad.

9 3.3 ERC Environmental Measures and Controls The NRC environmental requirements during CRBRP construction are contained in NUREG-0139, " Supplement to Final Environmental Statement"' (SPES).8 The environmental control measures contained in the SFES primarily restate criteria contained in non-NRC permits and approvals identified in Appendix A.
Specific NRC criteria contained in the SFES Section 4.6.1.1 which address additional conditions which could be affected by site redress end will require consideration during site restoration are as follows:.
t Blasting restrictions (should Par. 3 rock removal be required)
' Access and encroachment on the Par. 4 Hensley Cemetary l-Site access road control Par. 10, 12 -
Transmission line maintenance Par. 13 Protection of critical Par. 16 ecological elements Fire prevention control Par. 19 4.0 - POTENTIALL USES FOR THE CRBRP SITE The site was dedicated to industrial-usg even before it was proposed for' the location of the CRBRP.3 A subgroup of the CRBRP Site Redress Planning Task Force investigated numerous potential uses for the site..The goal of the subgroup was to provide information regarding future uses of importance to the site redress plan.
Near term uses which could use some or all of the
\\,
current excavation were considered, but none were identified as likely in the FY 84-85 time frame.
Other specific alternative j
uses assumed fill'ing in the major NI excavation but were not baced on any specific redress options such as grading' elevations, i
etc.
Again, no near term uses were identified.
The following i
list was compiled-based on limited data regarding the possibility l
of relocating a _ planned project (e.g., coal gasification) or matching. a. potential' project to the site (e.g., a DOE l
8 NUREG-0139, "Eupplement to Final Environmental Statement Related to Construction and Operaticn of Clinch River Breeder Reactor Plant, Docket No. 50-537," October 1982.

HTGR demonstration plant Although any one of the specific uses listed above could emerge as a development option, it ~ was concluded that generalized
-industrial development is considered the type of use most likely to occur in the future.
Although no immediate uses of this kind
-have been identified, it was concluded that if redress commenced af ter the spring of 1985, such options would not be forclosed and, in view of the continuing maintenance of environmental controls at the site- (see sections 3.2 and 3.3) no significant adverse environmental impacts' would occur.
5.0 SITE REDRESS PLAN 5.1 General l
s The overall' objective of the plan is to reconfigure and redress the site to provide an environmentally stable, self-draining,
[
. self-maintaining and aesthetically acceptable site that can be left unattended.'
In planning for site redress, two general categories of conceptual options were considered:
L Topographic approaches which accomplish the objectives L
noted above and which preserve the potential of the site consistent with its previous dedication to future l
industrial use.
Completion or addition of site development features such l
as a railroad spur, a barge facility, sewage treatment plant, or a water line to enhance the value of the site for potential industrial uses.
4
{
11 5.2 Site _ Redress Criteria In addressing redress alternatives, the following criteria were assumed to apply:
Excavations will be filled at least to minimum elevations sufficient to provide self-drainage to the Clinch River.
No area outside the present cleared area will be disturbed.
Borrow materials to be used in backfilling excavations and topographic reconfigurations will be taken from locations on the site which are within the present cleared area.
Surf ace stabilization to assure erosion. control.
The area identified on plant construction drawings as the Craft Parking Lot, about 14 acres, with an average elevation of 836 will remain "as is. "
The area is currently environmentally stable and would be usef ul for any future industrial development.
Pre-engineered metal buildings and the dual batch plant will be removed while the substation will be de-energized.
On-site meteorological station will be de-energized and removed.
5.3 Conceptual Redress Alternatives Two conceptual schemes for accomplishing redress of the CRBRP Site were considered.
The two alternative approaches for site redress which appeared most feasible for further refinement and assessment are:
Alternate 1 - Backfill the NI excavation, the NCT
+
excavation and trench, and the ECT excavation to the general plant grade of 810.
Material to fill excavations would be takenfrom Spoil Areas 2, 3 and 6, the East Laydown Area, the CBI Area, and the South Plant Area.
This would provide a site with two major usable areas--the Craft Parking Lot (14i acres) and the general plant area at an average elevation of 810 (471 acres).
See Sketch 2.
Alternate 2 - Backfill the NI excavation, the NCT excavation and trench, and the ECT excavation to about elevation 780.
Establish a drainage " spine" f rom the
12 j
excavations in a plant south direction to the Clinch
(
River.
Material would be taken from Spoil Areas 2, 3 and 6,. the East Laydown Area and the CBI Area.
This would provide a site with three major usable areas--the Craft Parking Lot-(141 acres), the West Area (29i acres) and the East Area (251. acres).
The excavation and redress activities would result in a perimeter road along the north side of the plant area which would provide additional access to the lower portion of the peninsula.
The Bear Creek water line would be completed from the 3
present terminus of road station 50+00 to 71+30
-(approximately 2,000 feet).
See Sketch 3.
5.4 Advantanes and Disadvantaaes of Alternatives 1 and 2 Both alternatives meet all environmental requirements.
The principal advantage of Alternative 1 is that it provides the most flexibility for future use.
Except for the Craft Parking Lot, the site is lef t at one general elevation, about 810.
The disadvantages of Alternative 1 are the higher cost and longer i
construction schedule and less net usable acreage for industrial l
use.
To backfill the excavations with material to support industrial structures will require borrowing from and eliminating some presently stabilized fills.
i A preliminary estimate indicates that as much as 1.3 million l
cubic yards of material may have to be moved at a cost of about l
S6 million.
Optimistically, this work might be completed in seven. months..However, the schedule is sensitive to the final j
determination of the stability required in the excavation i
backfills.
The principal advantage of Alternative 2, other than lower cost and schedule-considerations, is that it provides the most net usable, stabilized area to support industrial structures.
Since the. excavations will be part of a drainage " spine," requirements for backfill wil1 ~ be. smaller than in alternative 1 and materj al l
can be borrowed f rom spoil areas and other non-stabilized areas.
.In addition, Alternative 2 includes the completed water line and additional access to the lower portion of the peninsula, both
~important development parameters for the potential development of l
the site for industrial purposes.
i L
The disadvantage of Alternative 2 is the less flexible site topography.
The reconfigured site will have three areas--the Craft' Parking Lot (14 acres), a West Area (29 acres), and an East l
- Area (25 acres).
This will not' provide as much flexibility in t
locating future. site improvements.
i A preliminary estimate for Alternative 2 indicates that about 750 thousand cubic yards of material may have to be moved at a cost of $3-4 million.

13 should be readily achievaole.
5.5 Comoletion or Addition of Non-Tooocrachic Features The completion'of the following non-topographic improvements which were planned, designed, and approved for construction by NRC in the authorization permit, were not completed during site preparation.. They would, if completed, enhance the value of the site for future use, but were rejected from consideration during redress due to the extreme high cost, environmental disturbance to areas currently undisturbed and the negative effect on the redress construction schedule of about seven months.
The barge unloading f acility adjacent to the access road at '
about road station 22+00.
It is estimated to cost about
$1.2 million.
The railroad spur from the K-25 spur to the site.
It is estimated to cost about $1.8 million.
If completed as pl anned, it would have limited value since it wculd be subject to severe security restrictions where it passes through K-25.
The sewage treatment plants on-site.
The designed plants would have a capacity of 65,000 gpd and are estimated to cost about $600 thousand to complete.
The addition of the following improvements would enhance the value of the site for industrial use:
Construction of a railroad spur to the site outside of the K-25 security fence (present design utilizes existing track l
through K-25).
An estimate has not been made for this routing, but it would be about 14,000 feet longer than the present -design, would require bridges over two roads and one creek, and thus cost considerably more than present design.
i Upgrading the existing gravel road that connects with State Highway 95 and the intersection of Bethel Valley Road which serves the National Laboratory.
This would provide a more direct route to the Pellissippi Parkway and to East I-40 via Route 95.
This.would be a major and costly construction task.
None of the additional improvements considered in this subsection were incorporated into either alternative due to their high cost, potential environmental impacts, and negative ef fect on the redress. construction schedule.
l 5.6 Conclusion Because of its lower cost, larger usable land area, and schedular i
14
~~
1 advantage Alternate 2 has been selected as the preferred approach to redressing the site.
Modifications to Alternate 2 have been
-made to provide an approximate 6 additional acres thereby maximizing usable land area.
The site will be reworked to leave it in a condition that is both environmentally and aesthetically acceptable; that is, self-maintaining and suitable for future use.
This work will
. include excavation of borrow material from the site to fill the existing excavations for the Nuclear Island, Normal Cooling Tower and Emergency Cooling Tower.
The site will also be re-graded.and seeded 'in. order that erosion and transport of sediment into the Clinch River can be kept within acceptable limits.
The design of
-new grades and the finish grading of the site will provide access and stabilized surface area suitable for future industrial use.
i_
The redress activities will comply with all applicable permits i
issued to the CRBRP and applicable. requirements.
Access to the Hensley Cemetery, will be maintained during redress of the site and remain af ter redress.
No area outside the present cleared
-and grubbed area will be disturbed during site redress work.
A plan of the proposed Modifications to Alternative 2 is shown on Sketch 4.
The major features of this scheme are:
(1) fill the Nuclear Island.and Emergency Cooling Tower excavations to an elevation which will facilitate natural drainage to the Clinch River and (2) fill the Normal Cooling Tower excavation to surrounding. grade elevation.
Materials to be used in backfilling these excavations will be taken from locations on the site which are within the present approved cle.aring and grubbing limits.
Selection of. borrow areas will give priority to areas where L
borrow will have the least impact on future industrial use of the
-site.
Excavation of materials from the borrow areas will be performed by. methods which will prevent run-off directly into the river.
In order to assure adequate stability of filled areas intended for future industrial use placement of fill will be controlled by specifying suitable lift thickness, compactive equipment and compactive methods.
-In addition to reigrading the site several non-topographic improvements are planned.
Temporary buildings and the Concrete Batch Plant will be removed from the site.
The foundations for these structures, the aggregate storage bins, the truck wash j
f acility, and miscellaneous equipment footings and oads will be demolished.
The 8". Bear Creek Water Line along the Access Road was terminated.at WM Station 50+100.
This line will be extended approximately 2,000 feet along the continuation of the Access Road to a point south of the N.I. Excavation.
l After the site has been re-graded the area will be stabilized by I
seeding or surfacing with aggregate.
After planted material and slopes have been established, the treatment ponds will be removed l
allowing the site to drain naturally to the Clinch River.
The i
.. -... - ~. - - - -... -. -
s 15 land will be included as an integral part of the forestry management program conducted by the DOE in this area.
Seer 11ings will. be planted as a part of that forestry management program.
Redress activities would be scheduled to commence af ter the spring of 1985.
Befcre commencement and during redress, all applicable environmental controls will be maintained (see sections 3.2 and 3.3).
If prior to commencement industrial uses for the site are identified and committed which are consistent with the longstanding development plan for the site, then redress would be affected in accordance with this plan on those areas of the site not committed to industrial use.
This plan will assure that the environment of the site is protected, consistent with preserving its previously dedicated potential for industrial use.

ENVIRONMENTAL CONTROL PLAN FOR MAINTENANCE AND REDRESS OF THE CRBRP SITE 1.0 PURPOSE, The. purpose of this plan is to establish and describe the environ-mental controls to be used during maintenance of CRBRP Site and then during. redress of the site.
Maintenance of the site and redress of the site are further described below.
This plan has been developed from the pert'inent requirements affecting the CRBRP Site, including but not limited to the Project's NPDES Per-mit Number TN0028801.and the Project's Erosion and Sediment Control PlM1.. prepared by Stone and Webster Engineering Corporation (SWEC).
This plan is to be continuously implemented from the time the Con-
.structor for the CRBRP (SWEC) is. relieved of responsibility for the site and another organization assumes responsibility for the site, by contract or agreement with DOE-CRBRP, until site redress has been com-pleted and adequate vegetation has grown to make the site environ-mentally stable.
e 2.' O DEFINITIONS.
T-
.+b i.
4 2.1 Maintenance of the Site. Maintenance of CRBRP Site during the s.
period from relief;of the C6nstruttor of site responsibility '
until the start.of redress construction.
y Activities at the Site during this perio'd will be limited to control of runoff and sediments, removal of construction materials and equipment,' removal of supsrstructures of: buildings A
i and removal of-the concretelbatch plant..

~~
t Activities _to be conducted will be primarily movement of soil and rock within the site to. reconfigure the topography to make the site self-draining and, to the extent deemed prudent, pro-
.. w vide stabilized areas for. future use. Standard earth moving
~
and placing equipment will'be used.
Incidental blasting of rock and concrete slabs / footings is anticipated.
Some drainage structures-(culverts) may be required.

~
Measures required by the Project's HPDES Permit, number TN0028801 u-.
and the Erosion and Sediment Control Plan are covered in the sec-tion Water Quality Control.
Centrol of fugitive dust from unpaved roads and limitations on open burning of wood products are detailed in the section Air Qualitv-Control.
Measures for controlling oil and oil spills are provided in the-section Liouid Waste Control.
Measures for disposing of solid wastes from the site are provided in the section Solid Waste Control.
Measures for protecting rare'and unusual plant species on the site
.are described in the section Rare and Unusual Plant Species.
Activities which are conducted at the site during either maintenance or redress and, ene, not covered by this plan and, two, regulated by Federal or State Agencies, will be controlled by separate plans.
Any permits required for such activities are to be obtained by the organi-zation conducting the activity and copies of plans and permits are to be provided to the DOE-CRBRP.,
4.0 DESIGNATION OF RESPONSIBLE INDIVIDUAL FOR ENVIRONMENTAL CONTROL The or.ganization responsible for environmental control of the site shall designate an individual to oversee environmental control activities.
DDE-CRERP shall be advised in writing of the name and i'i.
qualifications of the individual so designated and that he has the
- 77 authority to require ; implementation of environmental control q.
measures.
The. individual designated.shall plan for environmental control measures for specific activities and shall insure their proper 'im-

In the event that, effluent concentrations excee'd 50 mg/.1, the
.-contratfor shall evaluate system performance to assure that the system is operating as designed and that on-site controls are effective.
Contractor shall take appropriate corrective action
- as required.
-:. The water level in the runoff treatment ponds is to be controlled to prevent them from overflowing.
To accomplish this it may be necessary to pump water from one pond to another that has suf.ficient capacity.
1 The runoff treatment pond filters are to be maintained in good working condition.
In the event that siltation of the filters re-duces flow-through below design capabilities, filters shall be cleaned in a manner approved by DOE-CRBRP.
5.2 ~ Erosion and Sediment Control Durina Site Redress The primary method for controlling erosion on the site is to be by diverting as.much runoff as possible into the runoff treatment ponds to be filtered and discharged to the Clinch River. This is to be accomplished by maintaining the slopes of cut and fill areas so j
they will drain into treatment ponds. Earthwork must be sequenced to control the size' of areas draining into each treatment pond to-
- prevent their being overloaded.
The approximate maximum drainage area for each of the treatment ponds is,:
1 Pond.A 44 acres p---
Pond B 34 acres Pond C 48 acres Pond D 32 acres s
Pond E 82 acres IfL the size of drainage areas is not maintained, overloading of individual ponds may result.
In these circumstarices it will be necessary to control the water. level-in the overloaded ponds. To
'bj'~.
I
- accomplish this it will be necessary to have the capability of pumping water from the overloaded ponds to the ponds with excess
,j
' capacity.
I-Spoil areas and areas where large vo' umes of materials will be l
moved shall have barriers placed along the toe of the outer most slopes (where runoff flows toward the river), prior to start of earthwork until they ar,e stabilized, well vegetated and erosion is L

(
prevented. All affected areas shall be inspected after each rain-
.. Q.. '.l-?
fall to verify-that erosion is minimized and that erosion and E
f..'f. f 7 "
sediment' control structures are being effective.
Erosion control R.-,
features.shall be repaired, replaced, or, added as required to L. i.-
maintain effectiveness.
m y.u
?
Existing' erosion control measures presently in place protecting previously disturbed areas of the site are to be maintained as long as necessary.
If new problems develop new control measures are to be installed.

Sample analyses, re-i sults and inspection findines are to be r ported to the DOE-CR5RP j
promptly.
In the event that effluent concentration exceeds 50 mg/1, the contractor shall evaluate system performance to assure that the system is operating as designed and that on-site controls are effective.
Contractor shall take appropriate corrective action as required.
Disturbed areas which do not drain into treatment ponds are to have separate erosion control measures installed. Th'ese measures are to include straw dams, silt fences and others as required to minimize sediments reaching the Clinch River.
The runoff treatment pond filters are to be maintained in good 1
working condition.
In the event that siltation of the filters reduces flow-through below design capabilities., filters shall be cleaned in a manner approved by DOE-CRBRP.

5.3 Other Water Ouality Control
. There are two potential sources of water.on the site:
a well'at the Concrete Batch Plant Area and the Bear Creek Water Line. The well will be capped,and not used. The Bear Creek Water Line has 7
