EPA Five-Year Review Signature Cover (continued)

Deficiencies:Two general deficiencies, not affecting protectiveness, were identified:

• Leachate collection source control measures do not appear to be effective at minimizing further contaminantrelease to the ground water.

• There appears to be incomplete capture of ground water downgradient of monitoring well GA-29, as evidenced by 1,2-dichloroethane (EDC) concentration increases.

Recommendations and Required Actions:There are recommendations:

• Propose more efficient source control measures to shorten the time required for operation of the extraction wells

• Investigate the cause of EDC concentration increases at the well GA-29

• Collect additional information about ground-water quality and hydraulic head data for the area being monitored by wellGA-29

None of these recommended actions are required to ensure the protection of human health and the environment.

Protectiveness Statement(s):The remedy is protective of human health and the environment.

Other Comments:Consistently high levels of EDC were observed in several near-source area monitoring wells. This may indicatethat current remedial action – source control activities are having limited effectiveness at reducing contaminantconcentrations in near-source areas and that modifications may be needed to shorten the period of time required tooperate site extraction wells.

1.0 INTRODUCTION

This document presents the 5-Year Review Report for the BFGoodrich/AIRCO Superfund Site in Calvert

City, Marshall County, Kentucky (site) (Figures 1 and 2). This 5-Year Review Report was prepared by URS

Corporation under the direction of United States Environmental Protection Agency Region 4 (EPA), with

input from the Settling Parties, BFGoodrich Company (BFGoodrich) and the BOC Group (formerly known

as AIRCO). This review was conducted from January 2001 through June 2001.

The 5-Year Review was conducted in accordance with the EPA-approved Workplan, 5-Year Review,

BFGoodrich/AIRCO Superfund Site, Calvert City, Kentucky dated July 13, 2000 (Workplan). EPA has

prepared draft guidance describing the requirements of 5-year reviews: Comprehensive 5-Year Review

Guidance, EPA 540R-98-050 OSWER Directive 9355.7-03B-P, PB99-963214, Draft, dated April 1999

(Guidance Document [EPA 1999]). The approved Workplan utilizes review procedures in the Guidance

Document as appropriate to the remedial action ongoing at the site.

The purpose of the 5-Year Review is to determine whether the remedy at this site remains protective of

human health and the environment. The methods, findings, and conclusions of reviews are documented in

5-year review reports. In addition, 5-year review reports identify deficiencies found during the review, if

any, and recommendations to address them.

The site is categorized as requiring a statutory 5-year review. A statutory 5-year review is required if a

post-Superfund Amendments and Reauthorization Act (SARA) remedial action will result in hazardous

substances, pollutants, or contaminants remaining at the site above levels that allow for unlimited use and

unrestricted exposure. EPA must implement 5-year reviews consistent with the Comprehensive

Environmental Response, Compensation, and Liability Act (CERCLA) and the National Oil and Hazardous

Substances Pollution Contingency Plan (NCP). CERCLA §121(c), as amended, states:

If the President selects a remedial action that results in any hazardous substances, pollutants, orcontaminants remaining at the site, the President shall review such remedial action no less often thaneach five years after the initiation of such remedial action to assure that human health and theenvironment are being protected by the remedial action being implemented.

The NCP part 300.430(f)(4)(ii) of the Code of Federal Regulations (CFR) states:


3.0 BACKGROUND

3.1 PHYSICAL CHARACTERISTICS

BFGoodrich/AIRCO site is located in Marshall County, Kentucky, approximately 2 miles northeast of

Calvert City off Highway 1523 (Figure 1). The site is located near the southern bank of the Tennessee River

approximately 18.5 river miles upstream from the confluence with the Ohio River and approximately 4

miles downstream of the Kentucky Dam.

The site as referenced is actually two adjacent Superfund sites, the 2-acre BFGoodrich Landfill and the

2.75-acre AIRCO Landfill (Figure 2). The sites were named on the National Priorities List (NPL) in 1983

(BFGoodrich) and 1984 (AIRCO) and consist of the two landfills and a former burning and burial area

referred to as the Burn Pit Area. The BFGoodrich Landfill and the AIRCO Landfill were studied as one

entity because they are adjacent and they share a somewhat common history of use.

As part of the Remedial Investigation (RI) Remedial Investigation Report: BFGoodrich/AIRCO Site, Calvert

City, Kentucky dated March 14, 1988 (Remedial Investigation Report [Dames & Moore 1988a] activities,

geographic and geologic conditions were investigated and reported for the site and surrounding areas. The

terrain in the vicinity of the site is characterized by an alluvial floodplain and river bank along the Tennessee

River and a broad terrace capped by lacustrine deposits. The elevation of the active floodplain ranges from

the normal pool elevation of the Tennessee River at 302 feet above mean sea level (feet, msl) to about 320

feet, msl at the edge of the floodplain. The river bank rises abruptly at the edge of the active floodplain to

the terrace level typically greater than 340 feet, msl. The 100-year flood elevation is approximately 344.10

feet, msl (TVA, 1993). The terrace is a broad, relatively flat topographic feature that ranges in elevation

from about 340 to 350 feet, msl. The former Burn Pit Area is located on the terrace area at an elevation of

approximately 345 feet, msl.

A slough was also present in the immediate vicinity of the site, roughly parallel to the river (from east to

west) along the toe of slope boundary between the floodplain and terrace. The BFGoodrich and AIRCO

Landfills were constructed by blocking the western portions of the slough, and backfilling the resulting

depression with soil, construction debris, and other waste materials. Prior to construction of the landfills,

the slough channel had a bottom elevation of approximately 310 to 320 feet, msl.


3.2 AREA ENVIRONMENTAL ISSUES

3.2.1 Calvert City Wellfield

One environmental issue that prompted the BFGoodrich/AIRCO Remedial Investigation/Feasibility Study

(RI/FS) was concern that groundwater contamination from the site could potentially migrate toward the

Calvert City wellfield during floods in the Tennessee River. Data collected during the RI showed

conclusively that the Calvert City wellfield was not contaminated, nor were the upgradient wells at the site.

From the RI, it is now known that groundwater contaminants are not migrating toward the wellfield.

3.2.2 Tennessee River Water Quality

The Tennessee River flows approximately 22 miles from the Kentucky Dam to the confluence with the Ohio

River at Paducah, Kentucky. Many industries in the Calvert City area discharge permitted effluent to the

Tennessee River through the Kentucky Pollutant Discharge Elimination System (KPDES). The river is

generally classified for use as domestic water supply, primary and secondary contact recreation, warm water

aquatic habitat, and navigation. From River Mile 13, below the last industrial discharge in Calvert City to

the Kentucky Dam (River City Mile 22.4), the Tennessee River is classified as Outstanding Resource Water

(ORW) due to the discovery of endangered species of Tennessee River mussels. For practical purposes, this

essentially means that the warm water aquatic habitat criteria are to be maintained.

One former drinking water intake, Northstar Steel, is located on the Tennessee River downstream of

Kentucky Dam at River Mile 13.7. The Paducah Water Works’ intake is on the south bank of the Ohio

River, approximately 2 miles downstream of the confluence with the Tennessee River and approximately

20.5 miles downstream of the BFGoodrich/AIRCO site.

The presence of several contaminants in the vicinity of Calvert City and downstream to Paducah Water

Works has been associated with industrial effluent and contaminated groundwater discharge from the

industrial complex at Calvert City (Dames & Moore, 1988a). Northstar Steel now uses Calvert City water.

Also, Paducah Water Works has an activated carbon system for adsorption that is used as needed to reduce

organic contaminants to acceptable levels. Therefore, an exposure point by drinking water ingestion no

longer exists. Although incidental ingestion and dermal contact by recreational users is possible, the river

quality data that are available reflect multiple


failed to distinguish any differences between the two sites in the adjoining counties.

3.2.4 Threatened and Endangered Species – Marshall County

One avian species and three aquatic species, listed below, are likely protected by the Endangered Species

Act in Marshall County (U.S. Department of Interior, 1987).

Bald eagle – Haliaetus leucocephalus

Rough pigtoe – Pleurobema plenum

Orange-footed pearly mussel – Plethobasus cooperianus

Pink mucket pearly mussel – Lampsilis orbiculata

The gulf stick pearly mussel, Obobaria retusa, is classified as a “status review species” that may be listed

in the future.

The pink mucket pearly mussel has been found in the Tennessee River downstream of Kentucky Dam

(Sickel, 1985a, 1985b, and TVA, 1979). A mussel sanctuary between River Mile 17.8 and 22.4 was

established by the Kentucky Department of Fish and Wildlife Resources and an abundant number of mussel

species thrive in the sanctuary, especially between River Mile 17.6 and 18.2. The mussel habitats in this area

and in other areas of the river have been associated primarily with favorable bottom conditions in the river

channel, i.e., clean current-swept substrates. TVA (1987a) identified the maintenance of adequate discharges

from the Kentucky Dam as an important factor for the mussel’s continued existence in the area.

The area adjacent to the slough may provide a suitable habitat for the bald eagle; however, the highly

industrialized nature of the area will tend to deter their presence. If present, the eagles could prey on animals

that inhabit the site. If the animals were affected by the site, the possibility would exist for the eagle to in

turn be affected. However, because no studies of terrestrial animal populations were performed, further

evaluation of this pathway is not presented in the Endangerment Assessment (EA) (Dames & Moore,

1988b).

3.3 LAND AND RESOURCE USE

The BFGoodrich/AIRCO site refers collectively to three separate former waste disposal areas: the

BFGoodrich Landfill, the AIRCO Landfill, and a former burning and burial


area. Each area was operated under different conditions during different but generally overlapping time

periods. Former and current land uses are presented in the following subsections.

3.3.1 AIRCO Landfill

The AIRCO Landfill occupies approximately 2.7 acres. It is located directly west of a small creek that, for

many years flowed intermittently to the west toward the existing BFGoodrich property. The slough to the

east of the landfill is a remnant of the former creek.

AIRCO has owned the property on which the landfill is located since 1956. A 1984 site aerial photographic

analysis performed by the Environmental Photographic Interpretation Center (EPIC) states that filling

activity at the AIRCO Landfill was first noted in 1959 (EPIC 1984). In 1971, AIRCO sold its Calvert City

Chemical Division to Air Products & Chemicals, Inc. (Air Products) and signed an “Omnibus Easement

Agreement” allowing Air Products to lease the landfill. In May 1980, AIRCO terminated the “Omnibus

Easement Agreement” regaining possession of the landfill site.

3.3.2 BFGoodrich Landfill

The BFGoodrich Landfill occupies approximately 1 acre directly west of the AIRCO Landfill. It is also

located in a former creek channel made suitable for landfilling by the construction of dikes on the north and

west sides. This land was purchased from AIRCO in 1964. However, AIRCO retained access to the site with

a lease until 1965. It is unclear whether AIRCO used this land for waste disposal activities prior to 1964.

An aerial photograph from 1961 does not show filling activity on the land eventually purchased by

BFGoodrich.

3.3.3 Current Land Use

The current use of the site is limited to operation of the remediation systems. The landfills and Burn Pit Area

are fenced so that access by the public is unlikely. Projected land uses for the surrounding properties

adjacent to the site consist of potential further industrial development by Westlake Group on the south. The

ROD mentions the possibility of residential development in the immediate vicinity of the site although this

is unlikely owing to the heavy industry zoning classification of the area encompassing the Calvert City

Industrial Complex along the loop Highway 1523.


Human use of resources in the immediate vicinity of the site is limited to recreational fishing in the

Tennessee River and possibly to hunting in the forested areas east of the site. Groundwater or surface water

use as a drinking water supply is not known to occur because potable water is supplied to the community

water users (residential, commercial, industrial) by the Calvert City Municipal Water Works.

3.4 HISTORY OF CONTAMINATION


AIRCO used the landfill for the disposal of waste material from its Calvert City plant. The types and

quantities of all wastes that were placed in the landfill are not known and have only been estimated by

former plant personnel. An estimated total of 18,000 tons (dry basis) were alleged to have been disposed.

Some of the wastes allegedly buried in the landfill include caustics, acids, volatile organics, zinc acetate,

mercuric acetate, and mercuric chloride (Dames & Moore, 1988a).

From 1971 to 1980, Air Products used the landfill to dispose of approximately 14,000 tons (dry basis) of

ashes from coal operated boilers, off-grade or non-processible polyvinyl chloride solids, inert ferric

hydroxide sludge from the wastewater treatment plant, and a small amount of non-combustible construction

wastes.


From 1965 to 1973, BFGoodrich used the landfill to dispose of approximately 54,000 tons of inert and

non-hazardous wastes. From 1973 to 1980, the only material disposed of in the landfill was excavated dirt

from the adjoining plant site.

3.4.3 Former Burning and Burial Area

An area south of the BFGoodrich Landfill (Figure 2) was used for the burning and burial of wastes.

Approximately 2.6 million gallons of liquid chlorinated organic wastes were burned in pits between 1965

and 1968. Another area adjacent to the Burn Pits was used to bury approximately 370 cubic yards of

salt-brine sludge during a one time disposal event in 1972. From 1970 to 1983, scrap lumber and fuel oil

were burned in this area two to three times per year for fire-training.


3.4.4 Discovery of Contamination

In May 1980, an inspection by Kentucky Department of Waste Management (KDWM) disclosed a leaching

problem along the river side of the BFGoodrich Landfill. KDWM instructed BFGoodrich to correct the

problem, and BFGoodrich completed repair of the problem in June 1980.

3.5 INITIAL RESPONSE


Between 1956 and 1968 before Kentucky instituted a solid waste management program, the AIRCO Landfill

was operated without regulatory overview. In October 1968, AIRCO applied for and was granted a Solid

Waste Disposal Operation Permit by the Kentucky Department for Natural Resources and Environmental

Protection (KDNREP). When the site was leased by Air Products in 1971, KDNREP issued a renewal

permit for Air Products to operate the AIRCO Landfill.

In 1978, the AIRCO Landfill site was included on the Eckhardt List of potential hazardous waste sites in

the United States. After an inspection of the site, KDNREP instructed Air Products to construct a dike at

its northern boundary to protect the landfill from a 100-year flood. The KDNREP landfill operating permit

was cancelled in 1980 when Air Products discontinued use of the site. Air Products submitted a closure plan

to KDNREP for capping the landfill. The plan was approved by the KDNREP in October 1980 and the

landfill was capped in September 1981.

In 1984, the EPA’s nationwide program to rank abandoned or uncontrolled hazardous waste sites under

mandate of CERCLA initially ranked the site 459 out of 538 sites. As a result of that ranking, an RI/FS was

initiated to ascertain the potential threat to human health and the environment, it any, posed by the AIRCO

Landfill.


From its start-up in 1965 until 1968 before Kentucky instituted a solid waste management program, the

BFGoodrich disposal area was an unregulated industrial waste landfill. In August 1968, BFGoodrich

submitted an application to KDNREP for a Solid Waste Disposal Permit. The application identified the

types of wastes that were to be disposed of in the landfill, and also described the construction of a

compacted fill dike between the


disposal area and the Tennessee River to prevent the flow of leachate and erosion of the fill cover.

Additionally, the following measures were proposed:

• A drainage ditch was to be constructed on the south side of the disposal area to divert rainfallrunoff around the site;

• Disposal of refuse in the Tennessee River floodplain was to cease; and

• Putrescible wastes were no longer to be disposed of at the site.

Operations of the BFGoodrich Landfill continued under permit until 1973 when industrial waste disposal

at the site was curtailed. From 1973 to 1980, the BFGoodrich site was used solely for the dumping of

excavated dirt.

In 1978, the BFGoodrich site was included on the Eckhardt List of potential hazardous waste sites in the

United States. In response, KDNREP and EPA Region 4 personnel inspected the site several times in 1980.

In a May 30, 1980, inspection, state personnel noted an apparent “leaching problem” along the north (river)

side of the landfill, and instructed BFGoodrich personnel to correct the problem. In June 1980, BFGoodrich

used clay to seal the north face and to cap the disposal area, and graded the site to promote rainfall runoff

drainage to the west and away from the AIRCO property. In September 1980, the site was revegetated to

control erosion.

In 1984, the EPA’s nationwide program to rank hazardous waste sites under mandate of CERCLA ranked

the site 461 out of 538 waste sites. Consequently, an RI/FS was initiated to ascertain the potential threat to

human health and the environment, if any, posed by the BFGoodrich site.

3.6 CONTAMINANTS

The BFGoodrich Landfill was listed on the NPL in September 1983, and the AIRCO Landfill was listed on

the NPL in September 1984.

Through implementation of the RI/FS process, five general areas of concern were identified at the

BFGoodrich/AIRCO site. These included the BFGoodrich Landfill; the AIRCO Landfill; the former

BFGoodrich Burn Pit Area, areas of identified surficial soil and sediment contamination, and groundwater

migrating from beneath these areas.


3.6.1 CONTAMINATED SURFACE SOIL AND SEDIMENT

Section III of Attachment I to the Consent Decree (CD) required the Settling Parties to investigate the

possible presence of contaminated surface soils around the perimeter of the waste management units

described above. Results of these investigations were reported in the following pre-design documents: Phase

I Contamination Soil Limit Investigation, Revision 1 dated August 12, 1993 (Phase I [Dames & Moore,

1993a]) and Phase II Contaminated Soil Limit Investigation dated September 7, 1994 (Phase II [Dames &

Moore, 1994a]). A brief summary of the results of these investigations is presented in the following

paragraphs.

The Phase I investigation resulted in the identification of seven indicator chemicals of concern, and the

development of appropriate Remedial Action Levels (RALs) for each compound. Comparison of the Phase

I analytical results from samples collected within those areas defined in the ROD as “requiring soil

remediation” revealed that none of the samples exhibited concentrations of indicator chemicals of concern

above their respective RALs. During Phase II of investigation, analytical testing was performed on a total

of 39 surface soil samples collected from outside those areas previously characterized. Results from this

testing identified an approximately 16,000-square foot area, within and adjacent to the southwest corner of

the Burn Pit Area, that exhibited soil contamination slightly above the RALs. Since none of the samples

recovered from within the areas designated for surficial soil remediation in the RODs exceed the RALs

established as part of the Phase 1 pre-design investigation activities, removal of surficial soils from those

areas was not required. Based upon the extent of soil identified above the RALs during the Phase II

pre-design investigation activities (as discussed above), the volume of surface soil to be excavated has

changed from the previously estimated 5,000 cubic yards to approximately 900 cubic yards.

During the RI (Dames & Moore, 1988a), concentrations of volatile organic compounds (VOCs), PCBs,

PAHs, several metal species (arsenic, chromium, iron, mercury, and vanadium), and cyanide were identified

in one or more sediment samples collected from a drainage ditch on the BFGoodrich portion of the site. The

ROD specified that remediation of the sediments be accomplished by removal of sediments along the

drainage ditch north of the landfills.


3.6.2 GROUNDWATER

Results of the RI (Dames & Moore, 1988a) revealed the presence of groundwater contamination by VOCs,

principally 1,2-dichloroethane (EDC); semivolatile organic compounds (SVOCs); and low levels of

inorganic constituents. The detected compounds were generally similar in the affected wells, although the

concentrations varied considerably. In those monitoring wells in which groundwater contamination was

observed, total VOC concentrations ranged from 0.0012 milligrams per liter (mg/L) to 4,017 mg/L and total

SVOC concentrations ranged from 0.002 mg/L to 7.8 mg/L. EDC was the most commonly detected

constituent and was present at the highest concentrations in groundwater beneath the site.

Given the waste disposal history of the site, the most likely source of contamination in the area was believed

to be the Burn Pit, in which approximately 2.6 million gallons of liquid chlorinated organic compounds were

burned between 1965 and 1968. The highest concentrations of VOCs in groundwater samples at the site

were identified in the shallow monitoring wells located to the north and northwest of the Burn Pit. The

distribution of contaminants in groundwater beneath the site is presented in the RI Report (Dames & Moore,

1988a). It was postulated that the “slug” of contaminants introduced to the subsurface at the unlined Burn

Pit Area migrated downward to the groundwater and subsequently toward the river with natural groundwater

flow. The identified presence of elevated VOCs in subsurface soils beneath the Burn Pit during the RI

supported this interpretation.

3.6.3 CONCEPTUAL MODEL OF RELEASE

Further evaluation of the hydrogeologic and chemical data collected since the RI has resulted in

development of the following conceptual model of the release. The fine-grained lacustrine and interbedded

units of sand silt and clay, shown in the cross sections in Figures 3, 4, and 5, are of particular interest

because of their likely role in establishing the migration pattern of the release. It is believed that as the

downward-moving slugs of contaminants released to the burn pits reached the silt and sand layers

interbedded within the clay layers, lateral migration likely occurred along these preferential pathways.

Lateral migration would have occurred as:

• Gravity drainage of DNAPL through silt and sand along clay layers and through other discontinuitiesin the clay layers (e.g., vertical-subvertical microfractures)


• Advective transport of dissolved constituents within the groundwater flow field, as affected bygradient-altering phenomena such as bank storage during periods of high river stage, through silt andsand layers between the clay layers

• Adsorption of DNAPL and dissolved constituents into the clay layers.

The conceptual model for the areal extent of VOCs is that the unit of interbedded clay, silt, and sand serves

as the preferential lateral migration pathway in the vadose zone where present, and in the shallow

groundwater zone for the constituents released to the burn pit.

3.6.4 RESULTS OF ENDANGERMENT ASSESSMENT

Risk assessment findings were presented in the EA prepared for the site Endangerment Assessment,

BFGoodrich/AIRCO site, Calvert City, Kentucky dated March 14, 1988 (Dames & Moore, 1988b). The EA

presented the potential human health effects that may result from exposure to site releases in the absence

of any site remediation. The EA evaluated and interpreted physical, chemical, demographic, and geographic

factors at the site to describe and assess the extent of potential harm to the public. The EA process consisted

of the following four major components:

1. Contaminant identification2. Exposure evaluation 3. Toxicity evaluation 4. Risk characterization

These components collectively addressed the following key issues:

• Identification and quantification of contaminants in relevant media (e.g., air, water, soil,sediment, biota).

• Environmental fate and transport mechanisms within each medium, such as physical, chemical,and biological degradation processes, and hydrogeological evaluations and assessments.

• Exposure pathways and estimated extent of exposure.

• Exposed population(s).

• Toxicological properties of specified contaminants.

• Characterization of risk(s) associated with estimated exposure(s).


3.6.4.1 Contaminant Identification

As part of the contaminant identification and quantification component of the EA, 13 indicator chemicals

were selected from the 110 chemicals identified at the site during the RI. Selection of indicator chemicals

employed indicator scores based on measured concentrations, toxicity, mobility, and persistence. The

chemicals were ranked by their indicator scores for carcinogenic and non-carcinogenic effects. The ten

highest-ranked carcinogenic and ten highest-ranked non-carcinogenic chemicals were selected as initial

indicator chemicals. Because a number of chemicals have both carcinogenic and non-carcinogenic effects,

there was significant overlap between the two groups, and the list was narrowed to 15 chemicals. The

inorganic constituents arsenic, barium, and nickel were removed from the initial indicator list because their

concentrations in soil and sediment at the site were found to be similar to site background levels or within

the range of natural background levels for the eastern United States (USGS, 1984). In addition, groundwater

concentrations for arsenic, barium, and nickel are below MCLs or lifetime health advisory levels, and

surface water concentrations are within ambient water quality criteria or are near background levels. PCBs

have a high bioaccumulation potential and were added to the indicator chemical list because they were

detected in a soil sample and in sediment samples from the drainage ditch and the Tennessee River. PCBs

were not detected in groundwater samples from the site, and were not considered in the calculation of

Alternate Concentration Limits (ACLs) for the site. Therefore, PCBs are not considered as an indicator

chemical for groundwater quality.

The final indicator chemical list is as follows:

1,2-dichloroethane (EDC) 1,1,2,2-tetrachloroethane

carbon tetrachloride Trichloroethene

chloroform Chlorobenzene

1,1,2-trichloroethane 1,1-dichloroethane

benzene bis(2-chloroethyl)ether

polynuclear aromatic hydrocarbons (PAHs) PCBs (Soil and sediment only)

tetrachloroethene


3.6.4.2 Exposure and Toxicity Evaluation

Exposure pathways at the BFGoodrich/AIRCO site were evaluated for two land use scenarios: current use

and future use. Both scenarios evaluated the potential exposure by humans and aquatic species to

contaminants via the following media:

• Groundwater

• Soil

• Surface water

• Sediment

• Air

Under the current and future use scenarios, the EA evaluated complete exposure pathways to be dermal

contact/incidental ingestion of surface soil, ditch surface water, and ditch sediment. Although the air

inhalation pathway was considered complete, the evaluation indicated that the worst-case particulate

emissions were approximately zero. The EA also considered contact with groundwater to be a potentially

complete pathway under the future use scenario as a result of potential residential development of the area

between the landfills and Highway 1523. However, because of deed restrictions currently in place, this

scenario is no longer possible.

The EA estimated most probable and worst-case exposure point concentrations for the indicator chemicals

using data from the RI. The EA estimated the intake of indicator chemicals by ingestion, inhalation, and

dermal contact using absorption factors available from the literature, or for chemicals without literature

values, absorption factors for similar chemicals. The EA presented a detailed toxicity profile for each of the

indicator chemicals providing a synthesis of pertinent toxicological literature and data regarding actual or

potential toxic effects.

3.6.4.3 Risk Characterization

Included in the indicator chemicals toxicity profiles were the recommended standards, criteria, and

guidelines that were applicable or were considered by the EPA to be relevant and appropriate for

comparisons with projected concentrations of the indicator chemicals. Applicable or relevant and

appropriate requirements (ARARS) included drinking water maximum contaminant levels (MCLs),

maximum contaminant level goals (MCLGs), and


federal ambient water quality criteria (AWQC). ARARS were not available for dermal exposure to surface

or groundwater (Table 1). Accordingly, a health risk assessment was completed for all 13 indicator

chemicals.

Potential human health risks associated with current exposure by ingestion of surface soil and ditch sediment

contaminants at the site were outside the target risk range of 10-4 to 10-7 in the absence of remediation. The

worst-case current use scenario total risk was estimated to be 2.3 x 10-3. The primary contributors to the

worst case risk estimate were PAHs. The risk for the worst-case future use scenario, which included

exposure to contaminated soil, sediment, and groundwater by residents, was estimated to be greater than

the current use scenario. Table 2 presents a summary of the risk assessment findings of the EA.

4.0 REMEDIAL ACTIONS

The Report, Feasibility Study, BFGoodrich/AIRCO Site, Calvert City, Kentucky, dated March 14, 1988 (FS

[Dames & Moore, 1988c]), identified and evaluated a range of remedial alternatives for the site as required

by CERCLA, SARA, and the National Contingency Plan (NCP). The FS selected the most “cost-effective

remedial alternative that effectively mitigates and minimizes threats to and provides adequate protection

of the public health, welfare, and environment” (40 CFR 300.68(i)). The FS used the 13 indicator chemicals

selected in the EA to establish strategies for attaining ARARs for remediation.

The ARARs for site remediation strategies were summarized as follows:

• The ARARs for the landfills were solid waste disposal closure standards and the Kentuckystatute regarding structures on a 100-year floodplain.

• The performance standards for surface soil were established from the EA to reduce public healthrisks to within the target risk range.

• Under the current use scenario, the ARARs for groundwater were those target concentrationlimits (TCLs) at the site that would not exceed MCLs or AWQCs in the Tennessee River. TheTCLs were calculated in the FS using a relatively straightforward mass-balance approach. Underthe future use scenario, which incorporated groundwater use at the site, the ARAR was the MCLfor the portion of the site within the zone of influence of a potential water supply source.

• The performance standards for subsurface soil were based on reducing soil


contaminant levels so that leachable concentrations that entered the water table did not exceedthe groundwater ARARs.

The selection of site remedial actions resulted from a successive development and screening process. First,

the general response actions that addressed remediation of individual site areas were listed. These general

response actions were subdivided into specific technologies that were screened for applicability and

feasibility for remediation. Those technologies that passed this screening were assembled into

media-specific alternatives that address each of the site problem areas. These media alternatives were

reviewed to screen out those that were clearly infeasible or inappropriate. Environmental, public health, and

cost criteria formed the basis for this screening.

The media alternatives that were carried through were combined into the site alternatives, which address

remediation of the combined BFGoodrich/AIRCO site. Nine site alternatives resulted from this analysis.

Table 3 summarizes each component of the site alternatives in a matrix form together with economic

information.

4.1 REMEDY SELECTION

The objectives of the remedial action activities at the site, as stipulated in the ROD, were to:

• Contain the on-site contaminated groundwater plume by extraction and treatment

• Eliminate leachate production in the Burn Pit Area

• Bring the landfills into compliance with Kentucky statutes regarding structures on a 100-yearfloodplain

• Protect the public health and environment from exposure to on-site contaminated soils andsediments

Alternative 3 was selected by the EPA, through the ROD dated June 24, 1988, as the remedial alternative.

On June 29, 1992, BFGoodrich and BOC agreed to a Consent Decree (CD) for implementation of the

prescribed remedial action at the site. The remedial alternative selected for the BFGoodrich/AIRCO

Superfund Site included the following components:


• Groundwater monitoring

• Impose deed restrictions preventing residential development

• Construct flood protection dike around landfills

• Upgrade landfill clay caps

• Install leachate extraction system

• Pump contaminated groundwater plume and treat by air stripping

• Excavate surface soil and place in Burn Pit

• Install organic vapor recovery system in Burn Pit and cover with a RCRA cap

Attachment I to the CD further refined the selected remedy to include:

• Providing geologic assurance that the flood protection dike would adequately protect thelandfills;

• If necessary, installation of leachate sumps as part of remedial design activities and attemptingto correlate water levels within the leachate sumps and monitoring wells with the TennesseeRiver stage;

• Expanding soil remediation activities to include removal of surface soils exceeding soilremediation action levels (RALs) to be established for specific indicator parameters;

• Provide assurances that groundwater flow into the landfills shall be minimized such that releasesfrom the landfill, if any, shall not result in a statistically significant increase in site-relatedcontaminants to the Tennessee River upon attainment of groundwater clean-up goals as definedin the RODs;

• Provide assurances that the flood protection dike, as set forth in the RODs, meets the design andperformance requirements of KRS 151 for construction within a 100-year floodplain;

• Provide assurances that the flood protection dike shall be able to maintain structural integritythrough repeated flood events.

Site alternative 3 represented a cost-effective means of mitigating the threat to the public health, welfare,

and the environment. This site alternative met all ARARs and reduced public health risks to within the target

risk range.

The present landfill clay cap would be upgraded. A flood dike would be constructed to protect the landfills

from the 100-year flood. A leachate collection system would be


installed to prevent contaminants from being released into the groundwater or other media.

Contaminated surface soils would be excavated and removed to the Burn Pit Area. A RCRA cap would be

installed over the contaminated soils in the Burn Pit. Soils in this area above the water table would be

contained and isolated from all exposure routes. This approach to soils remediation attains

chemical-specific, location-specific, and action-specific ARARs.

The plume of contaminated groundwater at the site would be contained by installing excavation wells and

withdrawing water at a rate of 100 gpm. This rate would ensure that MCLs are achieved in the Tennessee

River. Contaminated groundwater would be treated to meet NPDES requirements and discharged to the

Tennessee River. Groundwater extraction and treatment would continue for 10 years, at which time the

plume of contamination would be such that MCLs in the Tennessee River are achieved without extraction.

The ROD established groundwater ACLs from the TCLs calculated in the FS. The ACLs are:

Indicator Constituent ACL (mg/L) Indicator Constituent ACL (mg/L)

1,2-dichloroethane(EDC)

8.5 1,1,2,2-tetrachloroethane

0.29

carbon tetrachloride 8.5 trichloroethene 8.5

chloroform 0.32 chlorobenzene 8.5

1,1,2-trichloroethane 1.0 1,1-dichloroethane 8.5

benzene 8.5 bis(2-chloroethyl)ether

0.051

fluoranthene 8.5 tetrachloroethene 1.5

acenaphthene 8.5

Groundwater monitoring would continue for a period of 30 years to ensure that the measures summarized

above are achieved.


Deed restrictions would be imposed at the site to limit future use and prevent residential development.

4.2 REMEDY IMPLEMENTATION

4.2.1 Remedial Design

The Remedial Design/Remedial Action Work Plan, BFGoodrich/AIRCO Site, Calvert City, Kentucky, dated

October 19, 1992 (RD/RA Work Plan, Dames & Moore [1992]) was prepared in compliance with the CD

and incorporated the requirements and guidelines of the following:

• Feasibility Study

• ROD

• Consent Decree

• Consent Decree Attachment I

• EPA “Superfund Remedial Design and Remedial Action Guidance” OSWER Directive9355.04-4A

The RDRA Workplan set forth the Statement of Work (SOW), reflecting the requirements of the CD and

ROD, required for the implementation of the RD/RA. The contents of the SOW are presented in Section 4.1,

above.

Remedial Design activities consisted of: pre-design studies; preparation of construction drawings and

specifications, including supporting engineering calculations; preparation of construction health and safety,

construction quality assurance, and construction sampling and analysis plans; and establishment of

post-construction operations and maintenance activities, including groundwater monitoring. These activities

were intended to support and document the remedial design's ability to achieve the Applicable or Relevant

and Appropriate Requirements as presented in the FS and ROD. Specific deliverables that were submitted

during the RD/RA program are shown in Table 4.

4.2.2 Remedial Action

The groundwater extraction component of the remedy, consisting of wells SW-1942, SW-1943, BW-1944,

BW-1945, and BW-1946, was installed as part of the adjacent former BFGoodrich Calvert City Plant’s

RCRA Plantwide Corrective Action Program (PCAP) in


1991 (Dames & Moore, 1992 [Well Installation]). These wells were activated in 1992 and have been in

operation since then. Extracted groundwater is piped to the C Stripper at the Westlake wastewater treatment

plant where it is treated by steam stripping. Performance reporting for the 5 BFGoodrich/AIRCO site

extraction wells has been conducted since 1992 as part of the semiannual PCAP Effectiveness Monitoring

Reports submitted to KDWM and EPA. Annual performance monitoring of the groundwater extraction

system required for the remedy has been conducted since 1998 and is explained in further detail in Sections

4.3.2 and 5.1.5.

The Remedial Action Report, BFGoodrich/AIRCO Superfund Site, Calvert City, Kentucky, dated August

1997 (Remedial Action Report, Dames & Moore [1997]) was prepared to describe construction of the

remainder of the site remedy. The Remedial Action Report presented information to support the certification

of remedial construction activities associated with the BFGoodrich/AIRCO Superfund Site.

As discussed in the approved design documents, the construction activities were separated into two discrete

phases in order to provide a mechanism for agency review of specific remedial construction materials and

protocols prior to their implementation. The Phase I construction activities were performed in May through

July 1996. In summary, Phase I (pre-construction activities) consisted of:

• Preparation of the Health & Safety/Contingency Plan,

• Finalization of the Construction Quality Assurance Project Plan, and

• Completion of the Phase II Borrow Investigation.

Following review and/or approval of the Phase I pre-construction documents, Phase II construction activities

were implemented. Phase II construction activities were conducted from June 1996 to June 1997. In

summary, Phase II construction activities consisted of:

• Site preparation,

• Consolidation of designated ditch sediment and surface soil,

• Installation of the vapor recovery system in the Burn Pit Area,

• Placement of subgrade fill and construction of Resource Conservation and Recovery Act(RCRA) cover system over the Burn Pit Area,

• Construction of cover system improvements over BFGoodrich and AIRCO Landfills,


• Installation of the leachate extraction system,

• Construction of flood protection dike,

• Seeding and mulching,

• Construction of the site fencing, and

• Site restoration.

The Phase I and Phase II activities were performed in substantial accordance with the applicable design

documents, except as noted. Additional information regarding implementation of the remedial construction

activities is presented in the following sections.

The Settling Parties retained Sevenson Environmental Services, Inc. (Sevenson) of Delmont, Pennsylvania

as the remedial contractor for the project. Sevenson was responsible for site preparation, consolidation of

designated ditch sediment and surface soil, placement of subgrade fill and construction of the RCRA cover

system over the Burn Pit Area, construction of the flood protection dike, and final site restoration. The

Settling Parties retained Dames & Moore to fulfill the role of the Quality Assurance Firm described in the

technical specifications, Remedial Action Plan, and Construction Quality Assurance Project Plan.

4.2.2.1 Phase I - Pre-Construction Activities

The Phase I - Pre-Construction Activities were initiated in May 1996 and were completed in July 1996. The

Phase I - Pre-Construction Activities consisted of preparation of the Construction Health and

Safety/Contingency Plan and finalization of the Construction Quality Assurance Project Plan. These

documents were submitted to EPA on June 13, 1996 and June 18, 1996, respectively.

As part of the Pre-Construction Activities, the Phase II Borrow Investigation was also implemented. This

investigation was performed to identify materials that achieved the project specifications for the various

earthen materials used on the project.

It should be noted that during the Phase II Construction Activities, Sevenson proposed an alternate source

of drainage material for the project. The alternate material source (Greer Borrow Source) was proposed due

to commercial obstacles with the approved source of the material (Old Hickory Clay Company). Samples

of the proposed alternate drainage


material analyzed by Simmons indicated that the sand met the criteria for drainage material, and a letter

dated September 19, 1996 was submitted to the EPA requesting the change. The proposed change was

accepted by EPA.

4.2.2.2 Phase II - Construction Activities

The Phase II construction activities consisted of site preparation, consolidation of surface soil and drainage

ditch sediment, installation of vapor recovery system, construction of RCRA cover system over the Burn

Pit Area, construction of landfill cover improvements, installation of the leachate extraction system,

construction of the Flood Protection Dike, installation of site fencing, and site restoration. These activities

are described in the following sections.

Site Preparation

The primary site preparation activities included erection of erosion controls, construction of the

decontamination area, extension or abandonment of specified wells, and abandonment of a fire hydrant.

Consolidation of Designated Surface Soil and Drainage Ditch Sediment

The approved design documents required that a designated area of surface soil outside the Burn Pit Area

be removed and consolidated within the Burn Pit Area. These documents also required that drainage ditch

sediment between two identified points be removed and consolidated within the Burn Pit Area.

Based on the results from two pre-design investigations, one approximately 10,000-square foot area of

potentially contaminated surface soil was identified for consolidation within the Burn Pit Area. As required

under Attachment I to the Consent Decree, the uppermost 18 inches of soil from this area was required to

be excavated and placed within the Burn Pit Area. Excavation and consolidation of the soil material was

completed on June 26, 1996. Additional excavation was also required within and around the former Surface

Soil Contamination Area in order to construct a proposed storm water drainage ditch and storm water

culvert.

The ROD specifies that remediation of drainage ditch sediments be accomplished by removal of sediments

along the specified section of the drainage ditch north of the landfills between Ditch Sampling Points 1 and

3 on the BFGoodrich portion of the site. On August 15, 1996, identified sediments were excavated from the

drainage ditch and


transferred to the Burn Pit Area.

Installation of Organic Vapor Recovery System

An organic vapor recovery system was installed within the Burn Pit Area to remove organic constituents

from the subsurface soil beneath the Burn Pit Area. The system accomplished this objective by utilizing a

positive-displacement blower to induct a negative pressure in each of the wells installed within the Burn

Pit Area.

In accordance with the approved design documents, 13 vapor recovery wells were installed within the limits

of the Burn Pit Area. The surveyed location of these wells are depicted on the as-built drawing, presented

in Appendix A. The slotted 4-inch-diameter stainless steel well screens (20-foot length) were connected to

the risers then installed such that the base of the screened interval corresponded to elevation 317 (feet, msl).

The blower system was connected to the wells through a network of Schedule 40 polyvinyl chloride (PVC)

pipe. The PVC pipe was connected to the top of each well using a vacuum-rated well cap. At each well cap,

a vacuum shut-off valve and pressure gauge have been installed.

Originally, vapor extracted from the well system was treated utilizing two 1,000-pound activated carbon

units, operated in series. The carbon units (along with the blower system) were installed in an equipment

shed located immediately north of the Burn Pit Area. In May 1998, vapor treatment was changed such that

vapor is now piped to the C-Stripper at the Westlake Plant, and the activated carbon units now serve as

backup treatment capability during stripper maintenance.

Pilot system operation of the Vapor Recovery System was conducted during the week of December 16,

1996. Observations during the initial operation suggested that the air conductivity of the subsurface soil

within the Burn Pit Area is lower than assumed for the design basis of the system. In response to this

information, several system and operational modifications were recommended.

Construction of RCRA Cover System Over Burn Pit Area

The approved remedial action required that a RCRA cover system be installed over the limits of the Burn

Pit Area. In accordance with the provisions of the design documents, the RCRA cover system consisted of

a 2-foot-thick layer of engineered fill overlain by a geosynthetic clay liner (GCL), a 40-mil high-density

polyethylene (HDPE) liner, a 1-foot-


thick granular drainage layer, and a 2-foot-thick vegetative cover layer. Prior to installation of the cover

system, fill material was placed to achieve the required minimum slope of 3 percent over the unit.

Construction of Cover System Improvements Over the BFGoodrich and AIRCO Landfills

The approved design required that the existing BFGoodrich and AIRCO Landfill covers be improved by

stripping approximately 4 inches of the existing vegetative cover, adding compacted low-permeability (k#1

x 10-7 cm/s) clay fill to achieve the desired grades (5-percent to 25-percent), and adding a 12-inch layer over

vegetative fill. Subsequent to design approval, the Settling Parties requested two revisions to the approved

Final Design with respect to the landfill cover system improvements. Each of these revisions was

subsequently accepted by EPA.

Installation of the Leachate Extraction System

The ROD required the Settling Parties to install a leachate extraction system to collect and remove leachate

that may pond upon the underlying relatively low-permeability strata beneath the BFGoodrich/AIRCO

Landfill Areas and the Burn Pit Area. In summary, the leachate extraction consists of a series of six sumps

located within the BFGoodrich/AIRCO Landfill Areas. Sumps LS-1, LS-2, LS-3, LS-4, LS-5, and LS-6

were installed to depths identified during pre-design investigations (which are 2 feet below the landfill

bottom elevations). Each of the sumps was equipped with a positive air displacement pump to convey

leachate, which collects in the sumps. In addition to the sumps in the landfill area, each of the vapor

recovery wells located within the Burn Pit Area was equipped with a positive air displacement pump. In

accordance with approved design, each of the pumps was individually piped to the Equipment Shed where

it discharged through a manifold to the temporary leachate storage tank.

Pilot system operation of the Leachate Extraction System was conducted during the week of December 16,

1996. During this period, collected leachate was pumped to the 1,100-gallon temporary leachate storage.

Each time the temporary leachate storage tank was filled, samples of the liquid were collected from a

sampling port located near the base of the container. Evaluation of the analytical results by BFGoodrich

personnel indicated the leachate can be treated to achieve the applicable KPDES discharge standards in the

existing BFGoodrich groundwater treatment plant. In light of this information, it was recommended that the

design of the leachate extraction system be revised to permanently convey collected leachate to the existing

groundwater treatment system. This system


modification was completed on June 2, 1997.

Construction of the Flood Protection Dike

The ROD required that the Settling Parities construct a Flood Protection Dike around the landfills to prevent

inundation of the BFGoodrich and AIRCO Landfill Areas from floodwaters. The approved design also

required that the Flood Protection Dike be constructed to a minimum elevation of 347.0, which is

approximately 2.9 feet above the estimated 100-year flood elevation.

In accordance with the approved design, the Flood Protection Dike was situated with the outboard crest

located approximately 5 feet riverward of the established unit boundaries. Due to the close proximity of the

AIRCO Landfill with the slough located on the east side of the site, it was necessary to construct a portion

of the Flood Protection Dike over the slough area.

Approximately 45,000 cubic yards of fill material was placed for construction of the Flood Protection Dike.

The height of the Flood Protection Dike achieved the requirements of the Construction Sampling and

Analysis Plan.

Installation of Site Fencing

After substantial completion of construction activities, a chain-link fence system was installed around the

Burn Pit Area, the BFGoodrich/AIRCO Landfill Areas, and along the outer crest of the Flood Protection

Dike. The constructed fence system is 6-foot chain-link fence and is equipped with three strands of barbed

wire. The fence was installed by AAA Fencing of Paducah, Kentucky.

Site Restoration

Following completion of the earthwork activities, site restoration activities were implemented. These

consisted of removing equipment and debris associated with the construction activities, fertilizing, liming,

and seeding and mulching soil areas disturbed by construction. Seeding and mulching activities were

performed by Holly’s Nursery of Calvert City, Kentucky. These activities were performed utilizing typical

landscaping equipment (tractor, leveling disk, and mulch/seed blower). Silt fences and rock check dams

were utilized to prevent erosion until the vegetative cover was established over the Flood Protection Dike

and BFGoodrich/AIRCO Landfill area.


4.2.2.3 Variances From The Approved Design

Remedial construction activities associated with the BFGoodrich/AIRCO Superfund Site were performed

in substantial conformance with the Final Design Report and the Construction Quality Assurance Project

Plan with no significant modifications or variances observed. The minor modifications/variances that were

implemented included:

• Rock rip-rap was utilized for erosion protection on the exterior face of the Flood ProtectionDike. This material was utilized in lieu of seeding with crown vetch as described in the FinalDesign documents. In addition, Kentucky Standard Specifications for Road and BridgeConstruction Seed Mixture I was used in lieu of crown vetch for the interior face of the FloodProtection Dike.

• The roadway culvert adjacent to the southwest corner of the Burn Pit Area was extended to thewestern drainage ditch, eliminating the depression adjacent to the roadway.

• Several minor modifications to the design drawings were implemented to facilitate futuremaintenance of the remedy. These modifications included constructing a gravel roadway on thecrest of the Flood Protection Dike, constructing a gravel roadway over portions of the AIRCOLandfill, installing an earthen ramp on the northeast corner of the Burn Pit Area, and installingstairways to storm water outlet facilities.

• As described in the January 22, 1996 letter to EPA, the upper vegetative layer of theBFGoodrich and AIRCO Landfill was scarified to a depth of 4 inches. This scarification wasperformed in lieu of material removal for those areas which did not require additional fillmaterial to achieve the required grades.

• The Construction Sampling and Analysis Plan required that elevation information be collectedto demonstrate removal of the upper 4 inches of the vegetative layer (for areas receivingadditional fill only) within the BFGoodrich and AIRCO Landfill. Elevation information for twosurvey grid points (E28+00, S1+00 and E28+00, S0+50) was not collected due to an oversightby the surveyor. Although survey data is not available for these two points, field observationsby Dames & Moore indicate that removal of the upper 4 inches of the vegetative layer in thisarea was performed in accordance with the technical specifications.

• As described in the November 1, 1996 letter to EPA, a composite geosynthetic clay liner andriverside soil blanket system was utilized in place of the low-permeability soil layers on thelandfill cover systems.


• A minor deficiency in quality control testing (failure to record lift thickness and to correlate fieldmoisture/density testing results with specific laboratory tests) was experienced during the initialfew days of the Flood Protection Dike installation. During construction of this portion of thedike, the material was periodically observed by Dames & Moore to be placed in maximum8-inch lifts and no deficiencies in the compaction procedure were observed. The quality controltesting deficiency was identified and corrected, and is not considered to adversely affect theperformance of the Flood Protection Dike.

• The proposed fence alignment adjacent to the Burn Pit Area has been modified to the west ofthe access road, and the fence separating the BFGoodrich and AIRCO Landfill has been omitted,in order to facilitate maintenance activities.

• Several isolated areas of apparently stained surficial material were observed in the vicinity ofthe BFGoodrich and AIRCO Landfill. EPA was notified of the presence of these materials andthe proposed remedial actions in letters dated July 15, 1996 and July 18, 1996. Following reviewby EPA, the proposed remedial actions were accepted. In accordance with the process describedin the July 18, 1996 letter, the areas of apparently stained surficial material were excavated bySevenson (to a depth not exceeding 1.5 feet) and consolidated within the Burn Pit Area (beneaththe RCRA cover system). Excavated areas within the limits of the AIRCO Landfill were backfilland compacted with approved low-permeability soil material (k#1x10-7 cm/sec) from theapproved Old Hickory Clay Borrow Source.

4.3 SYSTEM OPERATIONS/O&M

The Operation and Maintenance Plan, BFGoodrich/AIRCO Superfund Site, Calvert City, Kentucky, dated

May 1997 (O&MP) was prepared to address post-closure care requirements and activities. The main

narrative of the O&MP provides an overview of the site and the systems requiring operation and

maintenance, a description of the operation and maintenance requirements, and a discussion of the reporting

and record-keeping mechanisms. The individual modules within the O&MP provide the specific

requirements and procedures for implementing the operation and maintenance activities. Specifically,

modules are provided to detail the groundwater and surface water monitoring requirements, the sluice gate

maintenance procedures, and the process systems operation and maintenance procedures.

Operation and maintenance of the C-Stripper, which treats extracted groundwater and soil vapor from the

site, is performed by Westlake. Downtime due to C-Stripper maintenance is noted in the semiannual RCRA

PCAP Effectiveness Monitoring Reports. During the periods of C-Stripper maintenance, vapor treatment

occurs through activated carbon beds.


4.3.1 Description Of Normal Operation And Maintenance

Operation, inspection, and maintenance activities at the site are performed by Industrial Well Services, Inc.

(IWS) of Calvert City, Kentucky under the direction of Christian J. Orsborn the Remediation Project

Manager, on behalf of BFGoodrich. IWS keeps an onsite office and equipment storage facility at the site

and has maintained daily logs of operation and maintenance activities performed since system startup. These

activities include: mowing of the Flood Protection Dikes and landfill cover system vegetation, maintenance

of equipment (i.e., lubrication of transfer pump and air compressor bearings, checking air compressor belt

tension, etc.), and monitoring of system operation. In accordance with the provisions of the Operation and

Maintenance Plan, semi-annual inspections of the various remedial action components are performed. IWS

performs the inspections, and these include the following activities:

• Inspection of the condition/effectiveness of the site security devices,

• Inspection of landfill/Burn Pit Area cover systems for excessive erosion,

• Inspection of the drainage ditches for excessive sediment accumulation,

• Verification that the storm water pumping system is functioning effectively,

• Inspection of the groundwater monitoring well condition,

• Inspection of the Leachate Extraction Well pumping systems,

• Inspection of the Organic Vapor Recovery System equipment, and

• Review of the equipment maintenance schedules in order to verify preventative maintenance hasbeen performed in accordance with the manufacturer’s recommendations.

In addition to these maintenance activities, groundwater and surface water monitoring are conducted. These

activities are further addressed in Section 4.3.2.

4.3.1.1 Security Fencing

For security purposes, fencing and warning signs surround the BFGoodrich/AIRCO Landfill areas and the

Burn Pit Area. Semi-annual inspections of these features are conducted during the post-closure care period.

During the semi-annual inspections, the fence system and gates that surround the residual waste

management areas are inspected for breaches or serious damage.


4.3.1.2 Erosion Damage

Inspection for erosion damage is performed over the various cover systems as part of the semi-annual

inspections. A reconnaissance of the landfill area, flood protection dike, and Burn Pit Area is performed

during each inspection and significant bare spots and rutting is noted in the inspector’s field log. Areas of

erosion damage which are not of sufficient severity to warrant corrective action are monitored during each

subsequent inspection.

O&M Issues

As noted in the October 12, 1999 inspection report and reported in Semiannual Operation and Maintenance

Report, BFGoodrich and AIRCO Superfund Sites, Calvert City, Kentucky, dated October 29, 1999 (URS,

1999), a black tar-like material was observed on the surface of the AIRCO Landfill during the week of May

25, 1999. Representatives of The BOC Group believed the material was most likely a chlorinated wax (one

of the materials disposed at the landfill). In response to this condition, the area containing the wax material

was isolated with engineering controls and a sample was collected for subsequent analysis. The toxicity

characteristic leaching procedure (TCLP) analytical results indicated that the material would be classified

as a non-hazardous waste. Based on correspondence provided by the Remediation Project Manager, the wax

material and associated stained landfill cover soils were excavated, containerized, and incinerated at the

LWD facility in Calvert City, Kentucky. Approximately 31 tons of stained soil material was removed and

disposed as part of the excavation effort.

Following excavation activities, the removed landfill clay cover material was replaced with new clay

material (Old Hickory Clay Company). The new clay material was keyed into the existing landfill clay cover

in order to provide a continuous barrier. A minimum clay thickness of 32 inches was used to seal the landfill

cover. Following clay placement, an approximately 18-inch topsoil layer was placed over the disturbed area

and the area was seeded on October 4, 1999.

4.3.1.3 Mowing Activities

Semi-annual mowing and/or bush-hogging is conducted over the limits of the BFGoodrich/AIRCO Landfill

and Burn Pit Area to inhibit deep-rooted vegetative growth which may harm the effectiveness of the cover

systems. The mowing is performed using standard farming/landscaping equipment and will be scheduled

in the months of April and September to allow for visual identification of areas requiring repair or

revegetation.


4.3.1.4 Storm Water Management System

To enhance drainage and inhibit storm water run-on, the landfill and Burn Pit cover systems include a storm

water management system. Drainage ditches within and outside the unit limits are inspected during the

semi-annual inspections for damage due to erosion and significant sediment accumulation.

The flood protection dike is equipped with a storm water drainage system consisting of a 24-inch CMP

which extends through the flood protection dike near the northeast corner of the AIRCO Landfill.

Maintenance personnel operating the groundwater treatment system monitor river levels daily. During flood

conditions (e.g., when the river is above the outlet of the drainage pipe (elevation 326.1), the sluice gate is

manually lowered by maintenance personnel and storm water is permitted to temporarily pond on the

landfill cover. During flood conditions, the storm water pumping system is activated (concurrent with the

closing of the sluice gate).

Following activation, the storm water pumping system operates automatically by float switches. During

periods in which the sluice gate is closed and the storm water pumping system is active, the system is

inspected at least once per week to verify proper operation.

The storm water inlet discharge structures are inspected during the semi-annual inspections for significant

sediment and/or debris accumulation. The sluice gate system and storm water pumping system is inspected

on a semi-annual basis and maintained in accordance with the manufacturers recommendations.

4.3.1.5 Groundwater Well Maintenance

The wells associated with the groundwater monitoring program are observed at each semi-annual inspection

for evidence of damage to the casing, cap, or locking system.

4.3.1.6 Leachate Extraction System

Leachate extraction sumps are installed at 6 locations in the BFGoodrich/AIRCO Landfill area. In addition,

thirteen organic vapor recovery wells are installed in the Burn Pit Area. The components of the leachate

extraction system are inspected and maintained on a semi-annual basis. More frequent maintenance of the

air compressor and transfer pump (i.e., quarterly inspection of air compressor lubricant and valves, quarterly

lubrication of transfer pump, etc.) is conducted as needed and/or recommended by the manufacturer.


O&M Issues

As noted in the September 25, 2000 inspection report and reported in Semiannual Operation and

Maintenance Report, BFGoodrich and AIRCO Superfund Sites, Calvert City, Kentucky, dated October 31,

2000 (URS, 2000), the high-level indicator probes in the leachate sumps have been the subject of frequent

malfunction and are not currently operating properly. In lieu of use of the unreliable high level probes as

an indicator of possible pump problems, the flow totalizer for each sump will be checked frequently to

assess whether additional leachate has been removed or not. If the totalizer readings for any sump have not

been noted to increase, manual water level readings and/or leachate pump operation verification will then

be performed to assess the condition.

A mortar base has been poured into each of the wellhead and junction boxes in order to ease maintenance

and to keep them cleaner. Each wellhead and junction box has also been insulated. Pitless adapters have

been added to the leachate sumps.

4.3.1.7 Organic Vapor Recovery System

The 13 vapor recovery wells, also referred to as soil vapor extraction wells, consist of a slotted 4-inch

stainless steel well casing installed to depth of approximately 30 feet. The vapor recovery system is

maintained semi-annually to ensure efficient operation of the system.

O&M Issues

In May 1998, vapor treatment was changed such that vapor is now piped to the C-Stripper, and the activated

carbon units now serve as backup treatment capability during stripper maintenance. As noted in the October

12, 1999 inspection report and reported in Semiannual Operation and Maintenance Report, BFGoodrich

and AIRCO Superfund Sites, Calvert City, Kentucky, dated October 29, 1999 (URS, 1999), the Organic

Vapor Recovery System was tested to evaluate system efficiency. Vapor samples were collected from each

of the thirteen Organic Vapor Recovery System wells and analyzed for the historically predominant organic

compounds (vinyl chloride, 1,2 dichloroethane, and benzene). Based on the analytical results, the vacuum

was adjusted in five wells to increase the system efficiency and provide a higher overall mass removal rate.

These adjustments resulted in an approximately 176 percent increase in the organic removal rate as

compared to the average from the four previous sampling events.

In May 2000, IWS replaced a 3-foot section of deteriorated PVC in Burn Pit well BP-8.


Because vapor analyses in Burn Pit wells BP-1 and BP-2 have shown consistently low concentrations, these

wells were shut off in July 2000 in order to optimize performance of the remaining SVE wells having higher

vapor concentrations.

A mortar base has been poured into each of the wellhead and junction boxes in order to ease maintenance

and to keep them cleaner. Each wellhead and junction box has also been insulated.

4.3.2 Environmental Monitoring

Monitoring of groundwater and surface water is required during the post-closure care period. A summary

of the groundwater and surface water monitoring requirements is provided below. Detailed information

regarding the groundwater and surface water monitoring requirements, schedule, procedures, parameter list,

etc. is provided in Groundwater and Surface Water Monitoring Program (provided as Attachment 4 to the

O&MP).

With regard to the environmental monitoring activities, the Consent Decree includes several requirements

which should be noted. In accordance with Section XII of the Consent Decree, the Settling Parties are

required to notify EPA in writing at least 21 days in advance of sample collection activity, with subsequent

verbal notice not less than 3 working days prior to implementation of these activities. The Consent Decree

also requires that the laboratories used for analyses perform such analyses in accordance with EPA Contract

Laboratory Program (CLP) protocol. Laboratory analyses and validation activities will be performed in

accordance with the site-specific Quality Assurance Project Plan for Pre-Design and Remedial Design

Activities dated October 21, 1992.

4.3.2.1 Groundwater Monitoring

The objectives of the groundwater monitoring program are to:

• Monitor groundwater quality at the outer edges of the plume to determine if the plume ismigrating toward the Tennessee River or laterally due to dispersion

• Monitor the effectiveness of the groundwater extraction system

• Provide a warning of hazardous constituent releases that may represent an environmentallysignificant change in conditions, as indicated by the exceedance of alert levels

During the aquifer restoration period, the remediation monitoring program consists of the


following activities. Groundwater samples are collected annually from the effectiveness monitoring wells,

including the extraction wells, and analyzed for indicator parameters in order to evaluate the effectiveness

of the pumping program. Annual groundwater samples for indicator parameters are collected from the

background wells and downgradient monitoring wells to evaluate background water quality and the position

of the plume. Semi-annual groundwater samples are collected from the five extraction wells and analyzed

for the indicator parameters EDC and benzene only. In addition, piezometric levels in the wells listed in

Section 1.6 and the Tennessee River stage are measured on a quarterly basis.

Twelve indicator parameters were selected for the site based on the selection criteria established in the

Endangerment Assessment Report (Dames & Moore, 1988b). ACLs were assigned to each of the parameters

as presented in the Groundwater and Surface Water Monitoring Program (Dames & Moore, 1997).

When the annual sampling results indicate that ACLs are being achieved in the effectiveness monitoring

group (i.e., when the concentration of EDC and benzene in any given well approaches 125 percent of the

respective ACL for two consecutive monitoring events), and at the option of the Settling Parties, quarterly

indicator and piezometric monitoring may be initiated.

Quarterly indicator monitoring will be conducted to assess whether ACLs have been achieved. For each

indicator parameter, four quarters of monitoring data will be compared to the ACLs. If the ACL exceeds

the detected value of each indicator parameter, it will be determined that the remediation goals for the

aquifer have been achieved, and the groundwater collection system will be shut off. At this point, the 30-

year post-remediation monitoring period will commence.

Groundwater is collected from wells selected to achieve the goals of downgradient monitoring, remediation

effectiveness monitoring, and background monitoring. The downgradient horizontal and vertical extent of

the plume boundary is monitored from the Downgradient Monitoring Group. The Effectiveness Monitoring

Group and the Extraction Wells are used to monitor the effectiveness of plume remediation within the core

of the plume. Background Wells monitor water quality upgradient of the site and beyond the influence of

the extraction system. The monitoring wells are arranged in clusters of consecutively numbered shallow and

deep wells, with the odd numbered well having the shallow depth. The monitoring wells are distributed

within the groups as


follows:

Groundwater flow characteristics are determined from piezometric data collected from the above wells and

the following additional wells: GA-15, GA-16, GA-23, GA-24, GA-31, and GA-32.

4.3.2.2 Surface Water Monitoring

The overall goal of the collection well network is to eliminate the discharge of contaminated groundwater

to the Tennessee River. During the remediation monitoring program, Tennessee River monitoring will be

triggered only if downgradient wells GA-27 and GA-28 both show confirmed levels of indicator parameters

at concentrations greater than or equal to ACLs. If confirmation occurs, the Tennessee River will be

monitored annually for indicator parameters and every 5 years for TCL/TAL constituents.

4.3.3 Reporting and Record Retention

Semi-annual inspections and maintenance of the site will be conducted throughout the post-closure care

period. A report for submission to EPA is completed following each semi-annual inspection. In accordance

with the provisions of the Consent Decree, these reports are submitted to the EPA by May 1 and November

1 of each year. In the event that remedial actions are necessary, the actions will be identified and their

completion documented in the report.


Annual reports are prepared to meet the reporting requirements for evaluation of the effectiveness of the

extraction system. Reports are submitted by November 1 of each year. Each report summarizes the

evaluation of data compiled over the previous 12 months and includes discussions and/or graphical

representations of the following:

• Groundwater quality trends for extraction wells and select monitoring wells to evaluate theprogress toward groundwater quality restoration

• Data showing the comparison between piezometric elevations in the Tennessee River barrierwell network and the Tennessee River stage elevations

• Confidence interval analysis, if appropriate

• Seasonal variations in groundwater flow characteristics and groundwater quality

• Calculated quantities of contaminants removed from the aquifer

• The effects of system maintenance and down time on effectiveness of the extraction system

• Recommendations for improvements in the system, if appropriate

In accordance with the provision of the Consent Decree, the Settling Parties are required to retain

documentation and records relating to operation and maintenance for a minimum of six years after the

completion of the Remedial Action. These records are specified in the Health and Safety Plan (HASP) for

the system O&M (IWS, 1997) and include:

• Health and safety briefings and meetings records

• HASP signoff forms

• O&M staff training acknowledgement forms and certificates

These records are maintained by IWS and are kept in the onsite office trailer files. Forms for personal

protective equipment instrument calibration and safety violations are available, but have not been needed

for any O&M activities to date. After the 6 year period, the Settling Parties are required to notify EPA

within 30 days prior to the destruction of these documents.

4.4 PROGRESS SINCE LAST 5-YEAR REVIEW

This is the first 5-Year Review Report for the BFGoodrich/AIRCO Site.

5.0 FIVE-YEAR REVIEW FINDINGS

The 5-Year Review was conducted in accordance with the EPA-approved Workplan (URS, 2000). The

approved Workplan utilizes review procedures in the Guidance Document (EPA, 1999) as appropriate to

the remedial action ongoing at the site.

5.1 FIVE-YEAR REVIEW PROCESS

This 5-Year Review Report was prepared by URS Corporation for the Settling Parties under the direction

of EPA, with input from BFGoodrich and the BOC Group (formerly known as AIRCO).

This 5-year review consisted of the following activities: a review of relevant documents (see Section 12.0);

interviews with the Remediation Project Manager and the representative of the construction and the

operations contractor; and a site inspection. The completed 5-year review report, along with the approved

Work Plan, is available in the site’s information repository, the Marshall County Library, Calvert City

Branch. Notices regarding the performance and completion of the 5-year review were placed in


the local newspaper, the Lake News, Calvert City, Kentucky (Appendix B). An announcement and a

15-minute remediation review was made at the Calvert City Industrial Complex Citizens Advisory Team

meeting about the performance of the 5-year review on February 27, 2001 on behalf of BFGoodrich by

Christian J. Orsborn.

5.1.1 Document Review

The documents reviewed for this 5-year review report are referenced throughout this document and listed

in Section 12.0. The deed restrictions for both parcels (one each for BFGoodrich and The BOC Group) are

recorded at the Marshall County Clerk’s office and are reproduced in Appendix G.

5.1.2 Interviews

Because there is an ongoing presence at the site and the status of the remedy is known, interviews were

limited to the remedial project manager and the remediation operations and maintenance contractor. The

following individuals were interviewed during the site visit on January 23, 2001 as part of the 5-year review:

• Christian J. Orsborn, Remediation Project Manager

• Thomas Anthony, Industrial Well Service

Mr. Orsborn and Mr. Anthony made their project files and operations and maintenance records available

for the document review portion of the 5-year review and answered specific questions about their content.

A remediation status review was presented to the CCIC Citizens Advisory Team on July 23, 1996. Mr.

Orsborn added that since construction of the remedy, neither he nor any representative of BFGoodrich at

the Calvert City Plant had ever been contacted by a member of the public regarding any issue at the

BFGoodrich/AIRCO site.

5.1.3 Site Inspection

Representatives of EPA, the Settling Parties, and URS took part in the site inspection on January 23, 2001.

During the site inspection, the remedial systems were observed. The inspection evaluated the groundwater

and soil vapor treatment systems, the Burn Pit cap, SVE system and leachate collection wellheads, the

BFGoodrich and the AIRCO Landfill cap, selected groundwater extraction wellheads, the flood protection

dike, and the site fencing. The Site Inspection checklist is presented in Appendix C. Photographs from the

site inspection are presented in Appendix D.


All landfill caps were found to be in good condition. The vegetative cover was thorough and abundant, with

no trees or shrubs established.

The groundwater and soil vapor treatment system (C-Stripper, at the Westlake Plant) was found to be

operating and functioning properly. The five groundwater extraction wells at the site were withdrawing

water at an average rate of 100 gpm. The IWS representative, Mr. Anthony, stated that ongoing activities

were operating smoothly and that O&M issues are addressed as quickly as possible as they arise.

A review of the Health and Safety Plan (HASP) indicated it was sufficient to control risks at the site and

was properly implemented, except for the lack of Daily Health and Safety Meeting logs. Mr. Anthony stated

that IWS health and safety briefings are held before each O&M activity takes place and that these activities

do not occur daily. These “as-needed” briefings are summarized in the Weekly Safety Reports on file at the

onsite IWS office trailer.

The as-builts have been updated to reflect the conveyance of extracted soil vapor to the C-Stripper.

5.1.4 Risk Information Review

The following applicable or relevant and appropriate requirements (ARARs) were reviewed for changes that

could affect protectiveness:

• Drinking Water Standards and Health Advisories (EPA, Summer 2000, EPA 822-B-00-001)

• National Recommended Water Quality Criteria – Correction (EPA, April 1999, EPA822-Z-99-001)

ARARs for four of the contaminants of concern have become more stringent since the signing of the ROD

in 1988. These changes affect the protectiveness of the current ACLs. As a result of the recalculation of the

cleanup levels using the new values for the ARARs and the same mass-balance methodology employed in

the FS, the revised cleanup levels for 1,2-dichloroethane, carbon tetrachloride, benzene, and trichloroethene

are lower than the ACLs from the 1988 ROD as presented below.

Action-specific ARARs, setting controls or restrictions on hazardous substances, pollutants or contaminants,

have not become more stringent since the signing of the ROD. These ARARs include the Kentucky

regulations that may be more stringent or different from the federal RCRA regulations and additional media

not administered under the RCRA program.

5.1.5 Data Review

In accordance with the Groundwater and Surface Water Monitoring Program (Dames & Moore, 1997)

approved for the site, annual groundwater monitoring is conducted during the aquifer restoration period (i.e.,

continuous groundwater extraction). The effectiveness of the five extraction wells was assessed using a

combination of site-specific piezometric data and water quality data. Site-specific piezometric data were

evaluated to monitor actual effects of pumping on the piezometric surface. Water quality data, including

data obtained from monitoring wells and extraction wells, were evaluated for trends in concentrations of

indicator parameters as a means of determining whether water quality improved with continued operation

of the corrective action program and that the objectives of the program were achieved.


To date, three annual groundwater reports have been prepared and submitted to EPA: Dames & Moore

(1998) and URS (1999, 2000). The following information is summarized from these reports and is compared

against pre-remediation data collected during the RI.

5.1.5.1 Piezometric Data

Sitewide groundwater elevations were measured during the RI in October 1987 (Figure 6). At this time

before installation of the extraction wells, groundwater was flowing toward the Tennessee River under a

gradient ranging from approximately 0.001 in the terrace area to approximately 0.03 beneath the landfill

areas. Following installation and startup of the groundwater extraction wells in January 1992, groundwater

flow was induced toward the Tennessee River Barrier wells. Figure 7 shows the potentiometric surface map

from measurements collected in July 2000. The conditions shown in Figure 7 are typical of all previous

groundwater level measurements observed for the site since activation of the extraction system.

Potentiometric monitoring data collected at the site since activation of the extraction system in 1992 are

provided in Appendix F. During the July 2000 water level survey, the five extraction wells were operating

at an average combined pumping rate of approximately 135 gpm. The cones of depression around the

Tennessee River Barrier wells indicate that under current conditions the system is providing a hydraulic

barrier between the regulated units and the Tennessee River. In the third quarter of 2000 the natural

hydraulic gradient was pronounced (steep) as a result of the Tennessee River pool stage of 302.2 feet.

However, the cone of depressions observed around individual extraction wells, particularly BW-1944,

BW-1945, BW-1946, BW-1947, BW-1953, and SW-1942 indicate the extraction wells are capable of

maintaining the hydraulic barrier from the Tennessee River and preventing plume migration during periods

slightly exceeding pool stage.

5.1.5.2 Water Quality Data

The EDC analytical results prior to and during the remediation period are presented in Appendix E and

discussed in the following sections. Figure 8 shows the extent of the shallow EDC plume based on sampling

in October 1987, prior to remediation. Figure 9 shows the current plume configuration based on sampling

from July 2000.


Extraction Wells

Semi-annual sampling of the extraction wells for EDC and benzene as part of the RCRA effectiveness

evaluation program has occurred since January 1992. EDC trends in the site’s extraction wells are plotted

in Figures E-1 through E-3 in Appendix E. In general, BW-1944 and BW-1945 contained the highest EDC

concentrations and BW-1946 contained the lowest. Review of these data shows that wells BW-1946,

SW-1942, and SW-1943 have maintained EDC concentrations significantly below the ACLs since

extraction system activation in 1992. BW-1944 has also maintained EDC concentrations below the ACLs

but with more variation. Well BW-1945 EDC concentrations have fluctuated to above the ACL on several

occasions between 1992 and 1996. Since April 1996, EDC in BW-1945 has been below the ACL.

Mass Removal

Groundwater samples are collected from the extraction wells annually and are analyzed for the list of

indicator parameters. These data, along with the recorded discharge rate for the wells on the day of

sampling, were used to calculate annual EDC and TVOC mass removal rates. For sampling years 1992

through 1997, TVOCs mass was estimated based on the ratio of EDC mass to TVOCs mass for the years

1998 through 2000. The results are shown on Figure 10.

Total mass removal since activation of the five extraction wells in 1992 was on the order of 20,000 pounds.

EDC mass removal since activation is on the order of 5,000 pounds. TVOCs and EDC mass removal rates

are currently increasing from low values in 1998 and 1999, respectively. Wells BW-1945 and BW-1944

have been the most effective at removing mass of volatile constituents, with extracted TVOCs mass values

on the order of 15,000 pounds and 4,600 pounds respectively. Wells BW-1946, SW-1942, and SW-1943

extracted TVOCs mass values are significantly lower and are on the order of less than 200 pounds (Figure

10).

Effectiveness Monitoring Wells

The effectiveness monitoring wells are a group of four well clusters located in close proximity to the source

areas and represent constituent levels in the core of the plume. Table 6 shows the pre-remediation indicator

constituent results, from October 1987, compared against the current results from July 2000. The 2000

sampling results indicate that the ACLs were exceeded for multiple compounds in all four shallow wells

(GA-1, GA-11, GA-33, and GA-35) and in one of the deep wells (GA-2). Estimated limits of the


EDC plume in the shallow zone of the aquifer based on data from the 2000 sampling event is graphically

presented in Figure 9. Figure 11 shows that for most of the effectiveness monitoring wells (GA-1, GA-12,

GA-33, GA-34, GA-35, and GA-36), a larger number of detected compounds showed decreasing

concentrations between 1987 and 2000 than the number of detected compounds showing increasing

concentrations. As shown in Appendix E, EDC concentrations are increasing in well GA-1, and EDC

concentrations show no strong trend in wells GA-2, GA-11, GA-33, and GA-35.

Downgradient Monitoring Wells

The downgradient monitoring wells are arranged in four shallow and deep well clusters to the north and east

of the source areas between the Tennessee River and the extraction wells. Well clusters GA-21/GA-22 and

GA-25/GA-26 are located to the north-northeast of the source areas. Samples from these two well clusters

have been below detection limits for all indicator constituents in the 1987 and 2000 sampling events (Table

6). Indicator constituent concentrations in wells GA-27/GA-28 remain below ACLs at levels just above

instrument detection limits.

Downgradient monitoring well cluster GA-29/GA-30 is located due north of the Superfund Site Burn Pit

source area and northeast of another former waste organics burn pit, known as SWMU 3, on the adjacent

Westlake property (Figure 2). These two wells showed elevated amounts of several of the indicator

parameters. The ACL for EDC was exceeded in shallow well GA-29, and every detected indicator

constituent except benzene and bis(2-chloroethyl)ether showed a concentration increase relative to 1987

data in this well. The companion deep well GA-30 showed increasing concentrations in 10 indicator

constituents, however all are currently below their respective ACLs (Table 6).

Constituents at GA-29 most likely are the result of a release from the former waste organics burn pit, known

as SWMU 3, on the adjacent Westlake property. This area is being addressed under RCRA Corrective

Action.

As described in the RCRA-program required Revised Workplan, Corrective Action Program, Former

BFGoodrich Company Facility, Calvert City, Kentucky dated April 10, 2001 (RCRA CAP Workplan) (this

document is currently in review by Kentucky Division of Waste Management [KDWM]), SWMU No. 3 is

an unlined, 0.5-acre disposal area buried approximately 10 feet below grade located east of the barge slip

(Figure 2). The unit was used to burn a variety of plant wastes, including over 3,000 cubic yards of

chlorinated organics. The unit was active from 1962 until 1965. In 1966,


noncombustible residues from this landfill were bulldozed to the CERCLA landfill. Soil sample data

collected from this unit and vicinity have been submitted to KDWM as part of a Preliminary Design. A soil

vapor extraction/air sparging (SVE/AS) system has been installed in the vicinity of this unit and is awaiting

an operational agreement. These data indicate that the capillary fringe, the upper saturated soils, and the

upper aquifer contain significant concentrations of EDC.

It is likely that SWMU 3 represents a source of release, and that the interbedded unit of clay, silt, and sand

in the vadose and shallow aquifer zone (see Section 3.6.3) represents a preferential lateral migration

pathway in the subsurface. It is therefore likely that varying concentrations in GA-29, which intersects the

interbedded unit, may be the result of pulses of variable-concentration contaminant advectively moving

through the aquifer past GA-29 within the groundwater flow field induced by pumping at BW-1944.

The implication of the observed concentrations in GA-29, namely that concentrations approaching the ACLs

of constituents are present in the aquifer in close proximity to the Tennessee River (via the Barge Slip), is

also a source of concern under the ongoing RCRA Corrective Action Program at the adjacent Westlake site.

Because of this finding, the site has responded by implementing the following activities toward enhancing

the hydraulic barrier in the vicinity of the Barge Slip:

• Rehabilitation and activation of extraction well BW-1951 on May 25, 2001. This well is currentlypumping at approximately 20 gpm.

• Monitoring of potentiometric levels in the Barge Slip vicinity during the BW-1951 startup periodon a weekly basis after the Tennessee River stage falls to 304 feet msl.

• Contracting and other preparations to install a new extraction well, power supply, and dischargepiping in the vicinity of MW-22a. Activation of this new extraction point is currently planned tocommence on or before August 1, 2001.

Background Monitoring Wells

Background monitoring well cluster GA-37/GA-38 is located upgradient of the source areas near the

southern corner of the AIRCO Landfill (Figure 2). The shallow well GA-37 showed only an estimated

concentration of benzene (1:g/L), and no indicator parameters were detected in deep well GA-38 in the July

2000 sampling event. No


indicator constituents were detected in the October 1987 sampling event.

Other Monitoring Wells

In addition to the monitoring well groups discussed above, several additional wells in the vicinity of the site

are sampled to provide better plume delineation. Well cluster GA-3/GA-4, downgradient from the AIRCO

Landfill, showed increased concentrations of most of the detected indicator constituents between 1987 and

2000 (Table 6, Figure 11). The associated deep well, GA-4, showed EDC present at a concentration above

the ACL since 1999 (Appendix E). Shallow well GA-31, located downgradient of the BFGoodrich Landfill,

also showed high concentrations above the ACLs, but more indicator constituent concentrations were

showing a decrease than an increase in concentration between 1987 and 2000 (Table 6, Figure 11).

Surface Water Sampling

The overall goal of the extraction well system is to provide a hydraulic barrier to eliminate the discharge

of contaminated groundwater to the Tennessee River. Pursuant with the Groundwater and Surface Water

Monitoring Program (Dames & Moore, 1997) Tennessee River monitoring will be conducted only if

downgradient wells GA-27 and GA-28 both show confirmed levels of the indicator parameters at

concentrations greater or equal to the ACLs.

Sampling results throughout the remediation period to date do not identify any indicator parameters above

their ACLs in wells GA-27 or GA-28; and therefore, surface water sampling has not been required.

5.1.5.3 Soil Vapor Extraction System Data

As part of operation of the SVE system, weekly samples are collected from the vapor effluent stream and

the leachate effluent stream, and these samples are analyzed for EDC. Field tests conducted by IWS

indicated that the leachate stream was composed of approximately 70 percent Burn Pit leachate and 30

percent landfill leachate. Figure 12 shows the average weekly extraction rates and the cumulative extracted

mass of EDC from the SVE and leachate collection systems since data collection began in 1998. The total

mass and average rate of EDC extraction by the SVE system was consistently an order of magnitude greater

than those for the leachate system. The rate of EDC mass removal has decreased for the SVE system from

approximately 450 lbs/week in 1998 to approximately 270 lbs/week in 2000. Cumulative EDC mass

removal for these systems


was on the order of 57,000 lbs for the SVE system and 3,800 lbs for the leachate collection system (Figure

12).

6.0 ASSESSMENT

The following conclusions support the determination that the remedy at the BFGoodrich/AIRCO site

remains protective of human health and the environment:

Question A: Have Conditions External to the Remedy Changed Since the Remedy Was Selected?

• No Changes in Land Use: There are no current or planned changes in land use.

• No Changes in Known Contaminants, Sources, or Pathways at the Site: No newcontaminants, sources, or exposure pathways were identified as part of this 5-year review.

• Changes in Known Hydrologic/Hydrogeologic Conditions: Operation of the groundwaterextraction system has altered the natural groundwater flow pattern, as intended in the ROD. Thecones of depression around the Tennessee River Barrier wells indicate that under currentconditions the system is providing a hydraulic barrier between the regulated units and theTennessee River.


Question B: Has the Remedy Been Implemented in Accordance With Decision Documents?

• HASP/Contingency Plan: Both the HASP and the Contingency Plan are in place, sufficient tocontrol risks, and properly implemented. One exception is the lack of Daily Health and SafetyMeeting logs as specified in the HASP. IWS indicates that health and safety briefings are heldbefore each O&M activity takes place and that these activities do not occur daily. These “as-needed” briefings are summarized in the Weekly Safety Reports on file at the onsite IWS officetrailer.

• Access and Institutional Controls: The fence and warning signs are maintained. Institutionalcontrols are in place and no current or planned changes in land use at the site suggest that theyare not effective.

• Remedy Performance: As documented in the semiannual O&M Reports and confirmed duringthe site inspection for the 5-Year Review, groundwater and soil vapor treatment systems, theBurn Pit cap, SVE system and leachate collection wellheads, the BFGoodrich and the AIRCOLandfill cap, groundwater extraction wells, the flood protection dike, and the site access controlsare in place and performing in accordance with design documents. The remediation goal ofcontaining the plume of contaminated groundwater is being met by the operation of thegroundwater extraction system. Indicator constituent concentrations in the downgradient groupof monitoring wells indicate that no surface water sampling of the Tennessee River is required,although for shallow well GA-29, concentrations have increased since 1987, including an ACLexceedance for EDC in 2000.

• Contaminant Mass Removal from Groundwater: For the groundwater extraction andtreatment system, approximately 98 percent of the cumulative mass of removed TVOCs wasextracted by wells BW-1944 and BW-1945. Cumulative mass removal since activation of thefive extraction wells in 1992 is on the order of 20,000 pounds. Most of the group of effectivenessmonitoring wells show a larger number of decreasing indicator constituent concentrationsbetween 1987 and 2000. However, the primary indicator, EDC, shows no decreasingconcentration trend in any of the shallow effectiveness monitoring wells.

• Contaminant Mass Removal from the Vadose Zone: Cumulative EDC mass removal is onthe order of 57,000 lbs for the SVE system and 3,800 lbs for the leachate collection system.

• Adequacy of System Operations: System operations procedures are consistent withrequirements.


• Need for Optimization: Given the performance of the remediation systems documented inSection 5.0, it may be possible to optimize the groundwater and SVE system performance byincreasing the output from extraction points characterized by high constituent mass removal andreducing or deactivating points having low mass removal.

• Early Indicators of Potential Remedy Failure: Costs and maintenance activities have beenconsistent with expectations. Timely maintenance of affected systems has prevented significantdowntime and remedy failure. The increase in indicator constituent concentrations indowngradient shallow well GA-29 represents a potential shallow plume migration issue notadequately controlled by the current extraction system.

Question C: Has Any Risk Information Changed Since the Remedy Was Selected?

• Changes in ARARs: ARARs for four of the contaminants of concern have become morestringent since the signing of the ROD in 1988. These changes affect the protectiveness of thecleanup levels. As a result, the revised cleanup levels of 1,2-dichloroethane, carbontetrachloride, benzene, and trichloroethene are lower than the previous levels of the 1988 RODas presented in Section 5.1.4. Action-specific ARARs, setting controls or restrictions onhazardous substances, pollutants or contaminants, have not become more stringent since thesigning of the ROD.

7.0 DEFICIENCIES

Deficiencies were discovered during the 5-year review and are noted below. None of these are sufficientto warrant a finding of not protective as long as corrective actions are taken.

Deficiencies Currently AffectsProtectiveness (Y/N)

Lack of Daily Health and Safety Meetings logs as required by HASP N

8.0 RECOMMENDATIONS AND REQUIRED ACTIONS

Based on the ARARs becoming more stringent for 1,2-dichloroethane, carbon tetrachloride, benzene, and

trichloroethene, the groundwater ACLs for these compounds need to be revised, as follows, in order to

remain protective:


Constituent New ACL

1,2-dichloroethane 0.64

Carbon tetrachloride 0.43

Benzene 2.04

Trichloroethene 4.59

The new ACLS will be utilized for all subsequent groundwater monitoring and reporting for the site.

The HASP will be modified to eliminate the requirement for Daily Health and Safety Meeting logs. Instead,

per occurrence Health and Safety Meeting logs will be maintained. Experience has shown that contractor

health and safety are adequately protected by this change.

The Settling Parties will evaluate options for system optimization and present findings of the evaluation to

EPA within 6 months of this 5-year review report.

9.0 PROTECTIVENESS STATEMENT(S) BY EPA

The remedy is protective of human health and the environment. Protectiveness is largely maintained by the

effectiveness of barrier wells at arresting contaminant migration toward the Tennessee River.

10.0 NEXT REVIEW

Another 5-year review is required, and will be conducted in 2006. The scope of the next 5-year review is

anticipated to be the same as that presented herein.

11.0 OTHER COMMENTS

The apparent limited effectiveness of the remedial action – source control activities at this site for reducing

contaminant concentrations in near-source areas - should be addressed. EDC concentrations over time for

several near-source area monitoring wells (most obviously, effectiveness monitoring wells GA-1, GA-2,

GA-35 and also GA-3) show that EDC concentrations have been consistently high over the period of

monitoring shown.


This observation implies that remedial actions to address ground-water contaminant movement from within,

or beneath the source area(s) have not been fully effective, and may indicate that control of the burn pit

source, by leachate collection alone, is insufficient to minimize further contaminant release to the ground

water.

IX. OTHER REMEDIES

If there are remedies applied at the site which are not covered above, attach an inspection sheet

describing the physical nature and condition of any facility associated with the remedy. An example

would be soil vapor extraction.


X. OVERALL OBSERVATIONS

A. Implementation of the Remedy

The remedy was designed to protect the BFGoodrich/Airco Landfill from inundation during

seasonal flood events, provide an effective landfill cover to minimize infiltration, remove leachate

from the burn pit and BFGoodrich/Airco Landfill areas, extract soil vapor from the Burn Pit Area,

and extract and treat groundwater. All systems are operational and functioning in accordance

with the design intent.

B. Adequacy of O&M

The remedy components (i.e., flood protection dike, landfill cover systems, leachate extraction

systems, organic vapor recovery system, etc.) appear to be well maintained. In the isolated

instances where equipment has malfunctioned or failed, the equipment has been repaired and/or

replaced in a timely manner with minimal downtime. The current O&M procedures are effective

in maintaining the long-term viability of the remedy components.

C. Early Indicators of Potential Remedy Failure

No major issues. Following startup, it was discovered that the pipes/tubing within the leachate

extraction junction boxes was prone to freezing. This minor operational issue was addressed by

insulating each of the well head and junction boxes.

D. Opportunities for Optimization

The high level indicator switches installed in each of the leachate extraction wells has been shown

to be very prone to fouling and malfunction. This has resulted in the frequent erroneous

indication of high leachate levels. Rather than rely on the high level switches as the only

indication of potential high leachate levels, manual measurement is also periodically performed as

an additional monitoring task.


INTERVIEW REPORT

5-YEAR REVIEWBFGOODRICH/AIRCO SUPERFUND SITE

CALVERT CITY, KENTUCKY

Persons Interviewed: Christian J. Orsborn Remediation Project Manager

Tom AnthonyPresident, Industrial Well Services

Interview Date: January 22, 2001

Interview Conducted by: John D. Priebe, P.E.

What are the Remediation Project Manager’s responsibilities on the project?

Christian J. Orsborn is responsible for overall management of the site activities and ensuring that the siteactivities are implemented effectively on behalf of BFGoodrich and BOC.

What are the Industrial Well Services responsibilities on the project?

Industrial Well Services has been retained by the Remediation Project Manager to perform the requiredoperation and maintenance activities for the BFGoodrich/Airco Superfund Site.

Are the various remedial systems functioning effectively?

Yes. The components are functioning effectively.

Is there a continuous O&M presence?

The systems are generally designed to operate automatically. O&M personnel are at the site Mondaythrough Friday during normal business hours.

Have there been any significant changes in the O&M requirements, maintenance schedules, samplingroutines since start-up?

No. The current requirements and schedules are effective.


What O&M problems has the site experienced?

The O&M problems the site has experienced have been relatively minor. For example, we found that thepiping within the leachate extraction well head and junction boxes was prone to freezing during extendedperiods of cold weather. This condition was addressed through insulating each box.

In addition, the high level indicators present in each of the leachate extraction sumps are prone tomalfunction resulting in wrong indicator readings. We have addressed this issue by implementing periodicdirect measurement of the leachate levels in each sump.

Have there been any other changes to the components since you have been involved with theproject?

With the exception of connecting the leachate and vapor flows to the RCRA Corrective Action TreatmentPlan, the changes have been minor.

For example, a mortar base was poured in each of the wellhead and junction boxes. This has enabled us tobetter maintain these boxes and keep them cleaner. We have also added pitless adapters to the leachatesumps.

Where are the O&M files kept?

The operation and maintenance files are maintained in the site trailers. In the office of the trailer, you willfind the various O&M documents including the daily operational logs, well logs, health and safety plan,repair logs, visitor register, etc.

Do you feel your current Health and Safety Plan is adequate for worker protection duringimplementation of the required O&M activities?

Yes. All of the site employees are appropriately trained and we hold formal site safety meetings on a weeklybasis. In addition to this, informal safety meetings are held on a daily basis.

Have there been any safety incidents since you have been involve with the project?

No.

Have you observed any evidence of trespassing at the site?

We have not seen any evidence of people trespassing at the site. However, occasionally a deer has beenknown to jump the fence. When this occurs, the deer is chased out without incident.


Have there been any erosion problems with the landfill caps or drainage ditches?

We have only seen minor evidence of erosion. It has been our objective to stabilize any observed minorerosion areas before these become significant issues. There are reporting criteria for erosion rills in theOperation and Maintenance Plan. We have never experienced a reportable event.

Do you have any suggested ways to optimize the operation, maintenance or sampling efforts?

No. The current activities are efficient and effective.

Have there been any complaints regarding the site or site activities?

We are not aware of any complaints.
