for National Priorities

List Sites (OSWER

Directive 9320.2-22).

In 

# June 2005,

the EPA approved

the Remedial

Design

(RD)

work

plan prepared

by

the potentially responsible

party (PRP),

which

was developed

in accordance

with

(ESD)

for

the Site.

The EPA

and

the Alabama Department

of Environmental

Management (ADEM) conducted

a final inspection

on August

28, 2008. During

this inspection,

the EPA

and ADEM determined

that

the Redwing

Site

PRP constructed

the remedy

in accordance

with

the

RD plans

and specifications.

The

PRP

has completed

remedial construction

activities

necessary

to achieve performance

criteria.

No further remedial

action construction

activities are anticipated

at this Site.

The EPA

and ADEM

have agreed

that

this inspection

was sufficient

for

the purposes

of this FCOR

and have initiated

the activities necessary

to achieve

site deletion.

As such,

this Site meets

are

as follows:

•

All remedial

have

been completed,

and

the selected

and •

No institutional

are required

since

the Site attained

the cleanup

goals

for unrestricted use,

as established

in the ROD, AROD

# II. SUMMARY

OF SITE CONDITIONS Background The

Site

is 5.1 acres

in size

and

is located

in the City

of Saraland,

Mobile

County, Alabama.

The

Site

is bounded

to the east

by U.S. Highway

43 and

a skating

rink.

To

the north,

it

is bounded

by

a United

Gas Pipe

Line easement

and

a mobile

home community,

to the south

by

a residential development,

and

to the west

by

an undeveloped

lot. The

Site

was

the former location

of the Saraland Apartment

Complex (Apartments)

that

has since

been demolished

to allow

for

the complete remediation

of the Site. Figure

lb. From

1961

to 1971, Redwing

Carriers,

Inc. (Redwing),

a trucking company,

owned

and operated

the Site

as

a terminal

for cleaning,

repairing

and parking

its fleet

of trucks.

The company transported

a variety

of substances,

including

asphalt,

diesel

fuel, chemicals

and pesticides

from

local plants. Redwing discharged

untreated hazardous

substances

to the ground

during

the cleaning

of tanker

trucks, creating

a tar-like

sludge

and contaminating

Site soils.

The tar-like

sludge

was composed predominately

of polycyclic aromatic

hydrocarbon

compounds

together

with lesser amounts

of pesticides,

herbicides

and volatile

organic compounds.

These operations

resulted

in contamination

of soils, groundwater

and sediment.

Figure

2 shows

the Site layout. In 1973, Saraland Apartments

Ltd. purchased

the Site

and built

a U.S. Housing

and Urban Development

(HUD) subsidized

apartment

complex

on

the Site. During construction,

the sludge

and contaminated

soils

were covered

with

up

to

5 feet

of clean

soil. When completed,

the complex consisted of

60 apartment

units located

in

12 buildings,

and

at one time housed approximately

160 residents, including

80

to

90 preschool-age

or elementary

school-age

children. In 1984, ADEM investigated

apartment

residents' complaints

about

the tar-like

sludge seeping

to the surface

at numerous

locations

at the Site.

In 

# 1985,

under Superfund

removal authority,

the EPA conducted

initial studies

in which

high concentrations

of

1,

2, 4-trichlorobenzene

and naphthalene

were detected

in the

soil

and

in leachate

coming

from

the sludge.

On July

8, 1985,

the EPA

and Redwing entered

into

a removal Administrative

Order

on Consent

(AOC)

that required

Redwing

to, among

other things, conduct

a limited

sludge

and contaminated

soil removal

action.

The

Site

was proposed

for listing on

the National

Priorities

List (NPL)

on June

24, 1998

(53

FR 23988)

and finalized

on February

21, 1990

(55

FR 6154)

due

to the potential

for consumption

of contaminated

groundwater.FinalCloseOutReportRedwingCarriers,Inc.(Saraland)SupenundSiteApril2015Figure2.SiteLayoutEnforcementandRemovalActivitiesPage4of14jOP...------<IQ:-.OnJuly2,1990,theEPAandRedwingenteredintoanAOCwhereinRedwingagreedtoconducttheSiteRemedialInvestigationandFeasibilityStudy.OnDecember15,1992,theEPAissuedaRODfortheSite.Redwingcontinuedperiodicremovalofsurfaceseepsuntil1994,whentheystoppeddoinganyworkattheSite.OnJuly5,1995,theEPAissuedaUnilateralAdministrativeOrdertoRedwingandSaralandApartments,Ltd.directingthemtoconductaremovaloftarseepsattheSite.Whenbothpartiesdeclined

FIVE- YEAR REVIEWS Pursuant

to CERCLA

section

121(c),

42 U.S.C.

§ 

# 9601

et seq.,

and

the EPA's

FYR Guidance

(EPA, 2001), because

this remedy

did

not result

in hazardous substances,

pollutants

or contaminants

remaining in the soils on-site

above

levels

that allow

for unlimited

use

and unrestricted

exposure,

no statutory

FYR of the remedy

is required.

The EPA

has

a policy

that

at least

one FYR

must

be conducted

after initiation of remedial

action

at the Site

to ensure

that

the remedy

is protective

of human

health

and

the environment.

The policy

FYR

was conducted

in 2014,

and

it concluded

that

the selected

remedy

at the Site

is protective

of human

health

and

the environment

because

the surface

soil, subsurface

soil, sediment

and groundwater

at the Site

met performance

standards established

in the 1992 ROD, subsequent

2000 AROD,

and subsequent

2007

ESD. The policy requirement

for

the FYR

has been

met,

and accordingly,

the Site FYR requirement

will

be discontinued.

Per

the EPA's

2001

FYR Guidance,

"Five-year

reviews

may

no longer

be needed

when

no hazardous substances,

pollutants,

or contaminants

remain

on-site

above

levels

that allow

for unlimited use

or unrestricted

exposure"

(UUIUE).

Since

the Site

is UUIUE

and

has

met

the requirements established

by

the ROD,

it

is not necessary

to conduct

another

FYR. 

# VIII.

SITE COMPLETION

CRITERIA The implemented

remedy achieves

the degree

of cleanup

and protection

specified

in the decision documents

for

the Site

for

all exposure pathways.

The selected

remedy

at the Site

is protective

of human health

and

the environment

because

the surface

soil, subsurface

soil, sediment

and groundwater

at the Site

met performance

standards established

in the ROD, AROD

and

the ESD.

The

Site does

not require any institutional

controls

since

the Site

was remediated

to residential

standards

to allow

for UUIUE.

All selected remedial

and removal

actions,

RAOs

and associated

cleanup

goals

are consistent

with

the

. EPA's

policy

and guidance;

these actions, objectives

and goals

have

all been achieved

and, therefore,

no further Superfund

response

is needed

to protect

human

health

and

the environment.
