INTRODUCTION

OBJECTIVE

This Removal Action Report (RAR) has been prepared by Montgomery Watson on behalf ofRockwell International Corporation (Rockwell) for the former Ralston disposal (Ralston) site inCedar Rapids, Iowa. This RAR is submitted as a requirement of the Administrative Order onConsent, Docket Number VII-93-F-004, entered into on January 22, 1993, between Rockwelland the U.S. Environmental Protection Agency (EPA). The purpose of this RAR is tosummarize the clay capping and creek bank stabilization activities conducted as part of theremoval action and to certify their completion, consistent with the May 1994 Removal ActionWork Plan (RAWP). Certification of the construction of the dual vapor extraction remediationsystem will be prepared at a later date, under separate cover.

SITE LOCATION

The Ralston site is located in the NE 1/4, NW 1/4, Section 2, T83N, R7W of Linn County, Iowa(Figure 1-1). The site is situated north of 228 Blairs Ferry Road in northern Cedar Rapids, Iowa.

The Ralston site consists of a former disposal area, a segment of Dry Run Creek, and a portion ofthe creek flood plain totaling approximately 1.5 acres. The steep banks of Dry Run Creek definemost of the northern edge of the former disposal area, whereas the south is bounded by theIllinois Central Gulf Railroad. The Ralston site is accessed via a gravel road north from BlairsFerry Road between the Bauer residence to the east and Don's Automotive to the west. A map ofthe Ralston site layout is presented as Figure 1-2.

BACKGROUND

Rockwell retained Montgomery Watson to provide project management assistance andconstruction management services for the clay cap and creek bank stabilization projects at theRalston site. Montgomery Watson prepared construction drawings and technical specifications(included in the RAWP) to allow Rockwell to competitively bid the project.

Following submittal and review of competitive bids, Rockwell selected WestinghouseRemediation Services, Inc. (Westinghouse) of Lakeville, Minnesota as the general contractor forconstruction of the clay cap and creek bank stabilization. Construction activities were initiatedon July 14, 1994, following a preconstruction meeting held at the site on July 13, 1994.Attending the preconstruction meeting were representatives of Westinghouse, MontgomeryWatson and Rockwell. The following is a brief summary of work activities that were performedat the Ralston site.

July 14 to August 5,1994

Activities included clearing and grubbing the site, completing general excavation, constructingthe key-in zone, conducting a survey of the general grade, and extending monitoring wells.Inclement weather caused some schedule delays.

SECTION 2


August 6 to 25, 1994

The clay cap was constructed, and a survey of the cap was conducted to ensure a min imum2-foot thickness was maintained. Inclement weather caused some schedule delays.

August 25 to September 10,1994

Activities included regrading the borrow areas, constructing terraces, placing topsoil, andinstalling a geomembrane liner on the creek bank.

September 12 to 19,1994

Placement of cabled-concrete mats on the creek bank began but was delayed due to an accidenton the site. Repairs to the geomembrane liner were conducted, and the topsoil placement wascompleted at this time.

September 19 to 22,1994

Placement of cabled-concrete mats on the creek bank was completed, and the creek crossing wasconstructed.

September 22 to December 20,1994

Activities included completing the final grading, constructing the drainage channels, terraces andaccess road, seeding the cap and borrow areas, and installing the post and rail barrier.

CONSTRUCTION OVERSIGHT

Montgomery Watson

Field inspection activities during construction of the clay cap and creek bank stabilization at theRalston site were provided by personnel from both Rockwell and Montgomery Watson.Inspection activities associated with the project included survey verification, contractadministration, and construction materials approval. Montgomery Watson was responsible forcompiling documentation of activities associated with construction of the clay cap and creekbank stabilization.

EPA Region VH

Personnel from CDM-Federal Programs (CDM), under the direction of the EPA, were on siteduring construction of the clay cap to monitor clay placement and compaction testing. Uponcompletion of the work, CDM personnel verbally expressed approval of the quality of capconstruction to Montgomery Watson personnel. On October 4, 1994 Susan Hoff, of the EPA,also reviewed the Ralston site construction.

SECTION 2

CONSTRUCTION ACTIVITIES

This section includes a description of individual tasks associated with construction of the claycap and creek bank stabilization at the Ralston site. Unless otherwise specified, all work wasperformed by the general contractor, Westinghouse.

SITE PREPARATION

Site preparation work commenced during the week ending July 15, 1994 and included clearingand grubbing of the former disposal area and borrow areas. The borrow areas, located west ofthe former disposal area (Figure 1-2), supplied the clay material for cap construction. Trees andother organic debris were stockpiled east of the former disposal area. The organic material anddebris encountered (pieces of scrap metal, concrete rubble, etc.) were hauled to the Cedar Rapidsmunicipal landfill upon careful visual inspection of the material by Rockwell personnel and fieldscreening with a photoionization detector. It should be noted that no hazardous material wasdelivered to the municipal landfill. The existing creek crossing also was removed at this time.

GENERAL EXCAVATION

General excavation activities conducted at the borrow area included the removal, segregation,and stockpiling of clay material to be used in construction of the clay cap. Vegetative cover wassorted and removed from the surface layer of the borrow area to ensure that the cap would be freeof organic material. Soil material from the first borrow area (Borrow Area #1, Figure 1-2) wastested for permeability prior to the initiation of construction activities (Appendix A). Thepermeability test revealed that the material would be suitable for cap construction. The soil wastested once again when work began to confirm the suitability of the material. The results weregenerally consistent with the earlier test (Appendix A). Visual observations by personnel fromRockwell, Montgomery Watson, Westinghouse and CDM were utilized to determine the generalsuitability of the material stockpiled for placement on the cap.

Clay Cap Extension

Following the excavation and completion of general grading activities, an initial survey wasconducted to establish the boundaries of the cap and appropriate cut and fill elevations during theweek ending July 22, 1994. During this period, ash and debris were found to extend beyond theoriginal cap boundaries. Two additional excavation pits, 4 feet and 20 feet deep, were dug alongthe eastern edge of the proposed cap to further define the extent of buried ash at the site. OnJuly 25, 1994 Rockwell, Montgomery Watson and Westinghouse personnel determined that thecap would be extended to the east and to the south due to the presence of additional buried ashuncovered in these areas. Several small investigation trenches were dug to aid in determining theextent of the ash present.

Once the boundaries of the debris were adequately defined, the existing fence along the southernboundary of the site was moved further south approximately 8 feet to accommodate the cap

extension. Following the decision to extend the cap, additional grading activities wereconducted. After general grading elevations were established, the former disposal area wassurveyed again to define the base of the cap. While excavating the key-in zones on the western

s edge of the cap, additional ash and scrap metal debris were encountered in this area. FollowingI this discovery, the decision was made by Rockwell to extend the western edge of the cap, and

small investigation trenches were used to define the extent of debris. The key-in zones were: constructed once the cap extension was completed.

Buried Drums

i On July 26, 1994, during completion of the general grading activities at the eastern edge of thecap, six concrete-encapsulated drums were unearthed. One of the drums broke open andimmediately was overpacked along with the surrounding soil. No release to the environmentoccurred. The others subsequently were overpacked and all six drums were stockpiled in apolyethylene lined, bermed containment area in the southwestern corner of the Ralston site.

< Eleven composite soil samples were collected on July 26 and 27, 1994 from the area where the• drums were unearthed, and results confirmed that a release to the environment had not occurred* _

(Appendix B). The results of these analyses were later rejected by the S-Cubed Division of• Maxwell, an independent data validation consulting firm, due to unacceptable matrix spike\ recoveries. On July 27, 1994, an empty broken drum was discovered in the area of the eastern

cap extension. On August 3, 1994 one additional concrete-encapsulated drum was discovered, atI the top of the creek bank, in the central portion of the site. These two additional drums werei overpacked and stockpiled with the other drums in the southwest corner of the Ralston site.

; Four grab samples were collected from the drummed material and analyzed for precious metals,• but no precious metals were detected in any of the samples (Appendix C). No additional analysis

was performed. Under the original hazardous waste profile for the site, the overpacked drums' were transported, by APTUS, to the APTUS disposal facility in Lakeville, Minnesota.1

CLAY CAP CONSTRUCTION

Placement of Clay

I A total of six lifts were placed to complete the clay cap according to the RAWP specifications.j Each layer of the compacted clay cap was completed by constructing a 4-inch lift of clay using

earth moving equipment. Montgomery Watson personnel provided necessary survey control to| maintain consistent 4-inch lifts. While placing each lift of the compacted clay cap, the contractori utilized a vibrating sheep's foot roller to achieve the necessary requirement of at least 95 percent

compaction. Before the sixth lift was placed, suitable material from the first borrow area was; depleted. Material from a second borrow area (Borrow Area #2, Figure 1-2) was used to1 complete approximately the last 1/4 of the sixth lift on the clay cap. Results of soil permeability

tests, performed on material from the second borrow area, confirmed the suitability of thej material and are included as Appendix D. Placement of the cap was completed on August 24,i 1994.

i Soil Testing Procedures

For purposes of verifying the permeability of the clay cap, the area was divided into five sections(Figure 2-1). This allowed soil testing to be tracked at a frequency of at least two field density

tests per lift, as required in the RAWP, and ensured adequate spatial variance in testing locations.Testing locations were randomly selected by Montgomery Watson and COM personnel and arepresented according to section and lift numbers in Figure 2-1. Field density tests were conductedby Terracon Consultants, Inc. of Cedar Rapids, Iowa. Field testing was achieved bymechanically scraping off the upper inch of each lift from the test area to provide a smooth gradefor testing. Density tests were then performed using a Campbell Pacific Nuclear (CPN) modelMC2 nuclear density meter. During construction activities, a total of 18 field density tests wereperformed as documented in Table 2-1 and Appendix E. A minimum of two passing tests wereachieved per lift before construction commenced on the following lift. An individual test wasconsidered passing if the result indicated a minimum of 95 percent compaction had beenachieved.

Monitoring Well Extensions

Monitoring wells MW-1A, MW-1B, MW-1C and MW-1D were extended on August 9, 1994. Ingeneral, the wells were extended in accordance with the RAWP or as determined by fieldpersonnel. Minor adjustments were made to the top-of-casing elevations. The final top-of-casing elevations of the extended wells are as follows:

SURVEY CONTROL

To maintain proper horizontal and vertical control during construction activities, MontgomeryWatson performed correctness of construction surveys to document proper horizontal locationsand vertical elevations. Montgomery Watson personnel established a temporary benchmark, atthe base of a monitoring well, for use during construction activities.

Additionally, Rockwell retained a local registered land surveyor to provide survey control duringconstruction. This subcontractor completed surveys of the general grade, top of the clay cap, andfinal grade elevations. The data was then correlated to design grade elevations, specified in theRAWP for each respective surface, to verify that a minimum 2 feet of compacted clay cap hadbeen established over the former disposal area.

CREEK BANK STABILIZATION

Gabled-Concrete Mats

Royal Concrete Products (RCP) was subcontracted by Westinghouse to provide cabled-concretemats and to supervise their installation on the creek bank. To avoid intrusive anchoring throughthe geomembrane liner on the creek bank, alternative methods of anchoring the cabled-concretemats were explored. Personnel from Westinghouse, RCP and Montgomery Watson discussedalternative anchoring options and found that nonintrusive anchoring could be accomplished byadding additional mats at the top of the bank to balance those placed on the bank slope. Themats then would be anchored sufficiently at the top of the bank with anchors specified by RCP.Rockwell favored this alternative, so RCP designed the cabled-concrete mats to be placed in thismanner. As directed by site contractors and Rockwell, additional clay material was added to thetop of the central portion and east end of the creek bank to increase the density of the soil forbetter anchoring of the geomembrane liner. Prior to placing the geomembrane liner,Westinghouse cleared and graded the creek bank to remove tree limbs and other organicmaterials, protruding scrap metal and trash. These materials were stockpiled and inspected byRockwell personnel for disposal in the municipal landfill.

At this time, site contractors also discussed alternative creek crossing designs with Rockwell. Arevised design, which incorporated the use of RCP cabled-concrete mats, was provided toRockwell (Figure 2-7). Because the cabled-concrete mats provide a more substantial resistanceto erosion from creek flow, the revised design was implemented.

The additional soil placed on the top and sides of the creek bank, and the redesigned extension ofthe cabled concrete above the top of the creek bank, resulted in the placement of considerablymore material (geomembrane liner and cabled concrete) along the creek bank than was specifiedin the RAWP. A total of 13,400 square feet of geomembrane liner and 17,840 square feet ofcable-concrete mats were placed on the creek bank. The placement of additional materialenhanced, but did not alter, the functionality of the creek bank stabilization.

Westinghouse personnel installed the cabled-concrete mat system, including the construction ofthe revised creek crossing, under the supervision of RCP personnel during the week endingSeptember 23, 1994. Anchoring was conducted in accordance with recommendations from RCPpersonnel. As-built drawings of the geomembrane liner and cabled concrete installation areincluded as Appendices F and G, respectively.

Geomembrane Liner

Geo-Synthetics, Inc. (GSI) was subcontracted, by Westinghouse, to provide the geomembraneliner and to assist in its installation. The liner materials, supplied by GSI, were reviewed byMontgomery Watson personnel and met the RAWP specifications. Westinghouse and GSIpersonnel installed the geomembrane liner during the week ending September 10, 1994.

DRAINAGE CONTROL

Construction of Terraces, Drainage Channels and Temporary Access Road

The terraces, drainage channels and temporary access road were constructed under thesupervision of Rockwell personnel. The approximate as-built locations of these constructioncomponents are included in Figure 2-8. The temporary access road was separated from the capby a filter fabric and was constructed using a 2-inch roadstone base overlaid by 1-inch roadstone.An October 21, 1994 review by Montgomery Watson personnel verified that the completeddrainage channels, terraces, and access road were constructed in general accordance with theRAWP. The post and rail barrier, placed along the access road at the bottom of the site entrance,was completed on December 20, 1994 following the construction review.

Seeding

Topsoil placement was conducted under the supervision of Rockwell personnel. Once finalgrading of the topsoil was completed, a final survey of the site, conducted by a local registeredsurveyor, confirmed that 2 feet of topsoil had been placed on the cap. Westinghouse retained asubcontractor to seed, fertilize and mulch the site following finish grading. Areas which receivedseeding included all disturbed areas within the former disposal and borrow areas. The seed mixplaced over these areas consisted of the following:

• Cap Only (per acre amounts)

2 Pounds Plains Coreopsis2 Pounds Black Eyed Susan2 Pounds Purple Cone Flower15 Pounds Little Blue Stem15 Pounds Sideoats10 Pounds Bluegramma50 Pounds Annual Rye400 Pounds 13-13-13 fertilizer

Project 1166.0180Rockwell International - Ralston SitePN 933127

Dear Mr. Coon:

Enclosed are the results of Standard Proctor compaction, grain size distribution, andfalling head permeability tests performed on a potential soil liner sample submitted fromRockwell International Ralston Site. The soils submitted consisted of a bulk disturbedsample delivered on June 11, 1993.

A Standard Proctor (ASTM D698) test was conducted on a representative soil sampleto evaluate compaction characteristics. A grain size test was also conducted on the soilsample. Results of the grain size and Standard Proctor tests are presented on the enclosedFigure Nos. 1 and 2.

Permeability characteristics of the potential soil liner sample was evaluated byconducting a falling head permeability test on soil remolded near 2 percent above optimummoisture content and compacted to approximately 91 percent of the determined maximumdry density. The remolded sample was 6 inches in length and the permeability test wasconducted by passing water through the soil sample under water heads ranging from 6 to 10feet The results of the falling head permeability test are provided on the following TableA.

If there are any questions concerning these test results, please contact us at yourconvenience.

Dear Mark:

The purpose of this letter is to provide the results of therequested laboratory soils testing for the above project. Thefollowing sections provide the test results or reference theattached graphs 'and tables as necessary.

Standard Proctor Compaction Test

One standard Proctor compaction test was performed in accordancewith ASTM D-698. The moisture/density relationship and testresults are attached.

Hydraulic Conductivity

Two hydraulic conductivity tests were performed in generalaccordance with ASTM D5084 on samples that were compacted in ourlaboratory. The results of these tests are tabulated below.

In summary, the sample compacted to 90% of the maximum drydensity did not meet the permeability specification of 1 X 10"cm/sec., and the sample compacted to 96% of the maximum did meetthis specification.

Specific Gravity

The specific gravity was computed based on the moisture contentof hydraulic test specimen 96 after testing (saturated). Thespecific gravity was determined to be 2.54.

Plastic and Liquid Limits

The liquid limit, plastic limit, and plasticity index weredetermined in accordance with ASTM D4318. The results of thesetests are shown on the attached Atterberg Limits Result sheet.

Grain Size Analyses

One grain size test, including sieve and hydrometer analyses inaccordance with ASTM D433, was performed. We have includedgrain size curves as well as tabulated results for theseanalyses.

If you have any questions concerning these results, or if we canbe of any further service, please do not hesitate to contact us.

Very truly yours,

Specific Gravity

The specific gravity was c.omputed based on the moisture contentof hydraulic test specimen 95 after testing (saturated). Thespecific gravity was determined to be 2.57.

Plastic and Liquid Limits

The liquid limit, plastic limit, and plasticity index weredetermined in accordance with ASTM D4318. The results of thesetests are shown on the attached Moisture Density Relationshipsheet.

Grain Size Analyses

One grain size test, including sieve and hydrometer analyses inaccordance with ASTM D433, was performed. We have includedgrain size curves as well as tabulated results for theseanalyses.

If you have any questions concerning these results, or if we canbe of any further service, please do not hesitate to contact us.
