ADDENDUM TO AS-BUILT CONSTRUCTION REPORT INTERIM STABILIZATION

CENTRAL CELL TAILINGS DISPOSAL AREA UNITED NUCLEAR CORPORATION

CHURCH ROCK FACILITY

1.0 INTRODUCTION

Interim stabilization of the majority of the centra! cell of the tailings disposal area

(central cell) was completed in 1990. The 1990 central cell construction and quality

control measures are documented in the As-Built Report, Central Cell Interim

Stabilization prepared by Western Technologies, Inc. (WT) in January 1991

(WT, 1991). This document is an addendum to the 1991 report and describes the

additional interim stabilization construction performed in the central cell during 1991

as documented by WT inspection reports.

Interim stabilization activities in 1991 included:

1. Placement of an interim soil cover over a 1.1 -acre area located immediately

north of the evaporation ponds, and

2. Placement of additional soil cover in the northeast portion of the central cell

over a 4.2-acre area that had experienced settlement.

Sheet 1 shows the location of these interim stabilization activities.

Nielsons General Contractors provided construction services to United Nuclear. WT

provided geotechnical sampling and testing services. The construction activities were

conducted from September 16, 1991 to October 7, 1991 in conjunction with similar

activities being conducted on the south cell. Descriptions of the daily construction

activities for both the central and south cells for this time period are presented in

Appendix A, Daily Review of Earthwork Construction.

CanonieEnvironmentdl

004333

The additional interim stabilization measures conducted in the central cell, as

documented by WT, were constructed in accordance with the Technical Specifications

and Construction Drawings presented in the "Tailings and Reclamation Plan As

Approved by NRC March 1, 1991, License No. SUA-1475" (Canonie, 1991). The

following sections of this addendum describe the interim stabilization construction

activities, provide quality control procedures and documentation, and present post-

construction monitoring results.

2.0 CONSTRUCTION METHODS AND EQUIPMENT

The interim soil cover placed in 1991 in both areas of the central cell was completed

with conventional earthmoving equipment. The soil was transported with scrapers

and placed with dozers and graders. Water was added and incorporated into the soil

with water trucks and a rome plow. A sheepsfoot compactor was used to knead the

soil and a pneumatic roller was used to further compact and seal the soil cover

surface. Table 1 presents a complete listing of the types of construction equipment

for the earthmoving operation.

The Technical Specifications in Appendix B of the Reclamation Plan (Canonie, 1991)

specified that the interim soil cover be placed in lifts up to 12-inch maximum

thickness, measured loose. This method was modified in the field to placing one lift

that measured a minimum of 12 inches after water processing and compaction. This

field modification was made to minimize contamination of the soil cover by the tailings

material, which could occur when working a thinner lift of soil with a rome plow and

sheepsfoot compactor. Adequate density and moisture content were achieved by

increasing the compaction effort and the amount of water added.

Unfavorable weather conditions did not allow for seeding these two portions of the

central cell after completing interim stabilization. However, mulch was crimped into

the soil to minimize the erosion potential. This mulch and volunteer vegetation by

native species is anticipated to be adequate to protection against the potential for

exposing tailings material until the rock armor is placed during final reclamation.

3.0 COMPACTION CRITERIA AND TESTING

Compaction criteria and testing for soil cover as specified in the Reclamation Plan

(Canonie, 1991) are shown below. These specifications require more testing than the

1990 specifications that applied during the previous central cell interim stabilization

activities. All criteria and testing rates were met or exceeded during the 1991

activities, as is discussed in Sections 3.1 and 3.2

Reclamation Plan Specifications

1. Soil cover is to be compacted to a minimum of 95 percent of the maximum

standard proctor dry density at a moisture content between optimum and

optimum plus two percent, as determined by ASTM D-698.

2. In-place field moisture density testing of the soil cover is to be conducted

at the rate of one test for each 500 cubic yards (cy) of cover soil and a

minimum of two tests for each day of cover soil in excess of 150 cy.

3. A full standard proctor test (ASTM D-698) is to be conducted per every 1 5

field density tests. A one point proctor test is to be conducted per every 5

field density tests.*

4. Gradation and classification testing of soil cover is to be conducted at a

minimum rate of one test each day of cover soil placement in excess of

150 cy and one test per 1000 cy.

* Note: One-point proctor tests were not conducted during 1991 central cell

activities. Full proctor tests were taken at twice the minimum rate to

sufficiently monitor soil compaction characteristics.

3.1 North of Evaporation Ponds

The 1.1 -acre area shown on Sheet 1 and located immediately north of the evaporation

ponds was previously graded and compacted in 1990. A 1-foot-thick interim soil

cover consisting of 1,926 bank cubic yards (bey) of clay was placed over this area on

September 16, 1991. The haul road embankment located on the west side of the

tailings area served as the borrow source for constructing the soil cover.

The soil cover consisted of sandy, silty, clays and sandy, lean, clays. Four gradation

and atterberg tests were conducted on this soil (i.e., one test every 482 bey) with all

tests meeting the required gradation specifications. The standard proctor test

performed on the soil yielded a density of 111.1 pounds per cubic foot (pcf) and a

moisture content of 15.8 percent. In-place field moisture-density testing was

performed by sand cone method (ASTM D-1556) on September 25, 1991. A total

of seven locations spread uniformly over the soil cover were tested (i.e., one test

every 275 bey) with all the results of tests meeting density and moisture

specifications. Test results for this area of interim soil cover are presented in

Appendix B.

3.2 Northeast Portion of Central Cell

The 4.2-acre area shown on Sheet 1 and located in the northeast portion of the

central cell experienced higherthan average settlement rates after interim stabilization

measures were completed in 1991. This area is located over the Borrow Pit No. 1

area, and the settlement is attributable to the large thickness of tailings deposited in

the borrow pit. A 1-foot-thick interim soil cover consisting of 6,645 bey was added

to this low area to reestablish the original design grade. The soil cover material was

obtained from the Borrow Pit No. 2 stockpile and was placed over a four-day period.

The original surface area was grubbed of vegetation before soil placement.

CanonieEnvironmental

004337

The soil cover consisted of sandy, silty, clays and sandy, lean, clays. Ten gradation

and atterberg tests were conducted on this soil (i.e., one test every 664 bey) with all

tests meeting the required gradation specifications. Three standard proctor tests were

conducted, and these tests yielded an average density of 112.8 pcf and average

moisture content of 13.2 percent. In-place field moisture-density testing was

conducted using the sand cone method (ASTM D-1556) at 23 locations spread

uniformly over the soil cover (i.e., one test every 289 bey). Initial testing on October

1, 1991 indicated that the majority of the locations exceeded the moisture content

specification. All failing areas were reworked until they met specifications. Test

results for this area of interim soil cover are presented in Appendix C.

004338

4.0 SETTLEMENT MONITORING

Nine settlement monuments are located throughout the reclaimed tailings disposal

area, placed in the areas of greatest fill and softest soil foundation conditions. One

of these settlement monuments, Settlement Monument No. 7 (SM-7) is located in the

northeast portion of the central cell.

SM-7 was surveyed before construction activities on July 8, 1991, and after

completing the interim soil cover on October 9, 1991. As shown on Table 2, the

monument settled approximately 0.23 feet during construction. Continued monitoring

after October 9, 1991 showed:

1. Settlement of 0.17 feet from October 9, 1991 to November 11, 1991,

2. Settlement of only 0.07 feet from November 11, 1991 to January 20, 1992,

3. Settlement of 0.18 feet from December 16, 1991 to March 9, 1992, and

4. Essentially no further settlement (i.e., less than 0.05 feet) from

March 9, 1992, until April 13, 1992.

The data suggests that 90 percent of primary consolidation has essentially occurred.

5.0 CLOSING REMARKS

Additional areas in the central cell of the tailings disposal facility have been regraded,

stabilized, and repaired with an interim soil cover in accordance with the specifications

and construction drawings contained in the Reclamation Plan. Settlement monitoring

indicates that settlement is decreasing and is not expected to impact the interim soil

cover/radon barrier.

SQii CQVCT MATERIAL

(North of Evaporation Ponds in Central Cell)

A soil cover material layer (1' thick) was placed on areas of

tailing materials. Soil cover material was obtained from the

Haul Road Embankment. Soil ranged from sandy silty clay

(CL-ML) to sandy lean clay (CL). Four gradation and atterberg

tests were taken from north of the Evaporation Ponds.

Nielsons Inc. used a rome plow (large disc) to process water

into the soil. A sheepfoot compactor was used to knead the

soil and a pneumatic roller was used to further compact and

seal the soil cover surface. Nielsons Inc. placed the entire

12 inch lift to prevent contaminating soil cover material from

underlying tailings material.

Seven field density tests were performed on material from north

of the Evaporation Ponds. All test locations met job

specifications. One proctor test was performed during North of

Evaporation Ponds soil cover placement.

UNC verified, using surveying methods, that at least one foot

of soil cover material had been placed on tailing materials.

SOIL COVER MATEKIAIf

(Northeast Portion of Central Cell)

A soil cover material layer (1' thick) was placed on areas of

tailing materials. Soil cover material was obtained from

Borrow Pit #2 Stockpile. Soil ranged from sandy silty clay

(CL-ML) to sandy lean clay (CL). Ten gradation and atterberg

tests were taken from the N.E. section of Central Cell.

Nielsons inc. used a rome plow (large disc) to process water

into the soil. A sheepfoot compactor was used to knead the

soil and a pneumatic roller was used to further compact and

seal the soil cover surface. Nielsons Inc. placed the entire

12 inch lift to prevent contaminating soil cover material from

underlying tailings material.

Twenty-three locations were tested for density in the N.E.

section of the Central Cell. Including retests and tests on

finish grade, a total of forty tests were taken on soil cover

for the Northeast portion of the Central cell. All density

tests (or their retests) met job specifications. Three proctor

tests were performed during Northeast Portion of Central Cell

soil cover placement.

UNC verified, using surveying methods, that at least one foot

of soil cover material had been placed on tailing materials.
