RE: Remedial Action Plan
Marine Maintenance Facility
Manns Harbor, N. C.
Dear Mr. Smithwick:
Additional information has been gathered through
considerable research and further sampling of the
contaminated material as outlined in the Remedial Action
Plan for the Marine Maintenance Facility at Manns Harbor,
N. C.
operational data and cost figures have been obtained
for the equipment that would 'be necessary to attempt
remedying of ground and/or surface waters that may be
contaminated within the construction area. The operational
data shows that the oil/water separator units will remove
hydrocarbons down to approximately 14 ppm concentration with
oil droplets 24 microns and larger being removed (Att. 1).
We currently have an oil/water separator unit approved for
disposal of bilge water from our marine vessels. The
effluent is permitted by NRCD to be released with a
concentration of 15 ppm or below. Through several
discussions with manufacturers, the air stripping towers
were determined to be insufficient due to the chemical
structure of the hydrocarbons being in the range that does
not lend itself to rapid evaporation.
Additional water samples taken and analyzed by an
independent laboratory, see Att. 2, show that the
concentration of hydrocarbons averages in the 6 to 7 ppm
range, with the highest being 11.13 ppm. The highest
concentration found is less than the permissible range of 15
ppm for discharge after remedying.
An Fnual nnwrt mity / Affirmative Actim Frrmnlorr
Mr. Rudy Smithwick

With this new information, the remedial action plan is
to be revised as follows:
Excavation
Those materials found to be contaminated with oil
residue or free product will be separated from normal
unsuitable material in the area outlined in the plan. The
contaminated soils will be hauled on D.O.T. trucks to an
area suitable for land treatment. This area is a 150 acre
site located in Washington County on State Road 1309, 0.3
mile north of SR 1308 (Att. 4). This property is owned by
the D.O.T. The material will be spread and treated by
D.O.T. forces until the hydrocarbons have evaporated to an
acceptable level.
Containment Procedures
The use of a cofferdam to enclose the excavation area
has been eliminated. Through value analysis, the cost of
$510,000.00 for the installation of a cofferdam is not
justifiable considering the low concentrations of
hydrocarbons and the near non-existence of heavy metals as
shown in the soil sample analysis, Att. 3.
The skimmed oil material will be disposed of either by
burning in an approved incinerator or by transporting to
South Carolina for storage.
Scheduling
The contractor will start excavating the contaminated
material as soon as approval is given by NRCD. The
contaminated material will be removed and then all other
unsuitable material will be disposed of according to the
existing contract.
Expeditious review of this revision is requested of you
and your department. Thank you again for working so closely
with D.O.T. personnel.
Sincerely,
E. N. McEntire, P. E.

FROM: John Par k
SUBJECT: Modification to DOT Marine Maintenance Facility, Permit #168-78
for the purpose of decontaminating an oil dump.
DATE: December 11, 1987
The attached material explains the efforts by DOT to decontaminate
an oil dump that dates back a number of years. It is my understanding
that there has been considerable communication with the DEM field office
in recent months concerning this matter. Containment during excavation
and final disposal are the two key issues.
It isrequested that you review -this from a viewpoint of CAMA permit
requirement's that would safeguard your, resp.ectiv-e interest in handling
the materials involved. It is requested that comments be submitted by
January 6. However, if, due to the nature of this matter, additional
review time is requested, please advise.

SUBJECT: MINOR MODIFICATION REQUEST FOR CAHA PERMIT #168-78;
D.O.T. MARIINE MAINTENANCE FACILITY AT MANNS HARBOR
DATE: November 23, 1987
The applicant requests a minor modification to CAMA permit #168-78
issued to DOT for the Marine N9aintenance Facility at Manns Harbor. During
preliminary construction of Phase V, DOT personnel discovered soils contaminated
with oils and oil residues. Construction activities were subsequently halted
and tests were run to determine the extent of the contamination.
To alleviate this problem, DOT proposes to modify permit #168-78 to
*
allow for the excavation of the contaminated soils. Once disposed of the
ex vated pit will be refilled ith clean, compactable soil To prevent
collapse of the pit banks, DOT `proposes to install a cofferdam around the
area to be excavated.
* DOT is currently working with DEN°1 to formulate a plan to dispose of tie
oil tainted soils.

REMEDIAL ACTION PLAN
MARINE MAINTENANCE FACILITY
NORTH CAROLINA DEPT. OF TRANSPORTATION
MANNS HARBOR, N.C.
The.Department of Transportation is currently in Phase V
of the construction of the marine maintenance facility
located on SR 1105 in Dare County. Attachment 1 of this plan
pinpoints the location on a road map of the county.
A portion of-this construction involves the removal of
existing buildings, excavation of unsuitable material,
backfilling this area with compactable soil and the building
of a bulkhead and anchor system. Attachment 2 of this plan
shows, the site layout and utility plan.
It has been determined that a portion of the
unsuitable material to be removed in the excavation is
contaminated with oil residue. There is also a possibility
that surface waters in and adjacent to the excavation site
could be contaminated by the presence of oil or oil products
that may be uncovered during the course of excavation.
. The source of the contamination is still not quite
certain. Through interviews with older employees and former
(retired) employees, it has been determined that several
years ago the finger of land in question was eroding at an
accelerated, pace To.stabilize'this ground, all kinds,"of
scrap metal and materials were pushed into the eroding area
to stop the movement. Various materials in a surplus and
junk pile that were used for stabilization include; creosote
timbers, old boat structures (wood), metal of various types,
engine blocks, scrap steel bridge beams, etc. There is a
possibility one or more 55 gal. barrels were pushed into the
area. The barrels may have had old used motor oil of an
unknown amount in them.
To determine how hazardous this contaminated material
is, twelve (12) soil samples and three (3) water samples were
taken in the area in question. See attachment 2 for the
locations. The samples were analyzed using the EPA
parameters for Toxicity and also to determine the petroleum
hydrocarbon concentrations. The EPA toxicity parameters
include the detection and measureable concentrations of
Arsenic, Barium, Cadmium, Chromium, Lead, Mercury, Selenium,
Silver, and the hydrocarbon concentration. The results of
these samples are shown in the Industrial & Environmental
Analysts, Inc. report which is attachment 3 and 4 of this
report.
2
The results of the analysis has determined that the
contamination is below all EPA limits for these materials.
Four (4) of the soil samples exceeded the 100ppm guideline
for oil contamination. This material will be segregated and
disposed of according to regulations administered by the
Solid and Hazardous Waste Management Branch of the Division
of Health Services in the North Carolina Department of Human
Resources. Any liquid materials recovered will be disposed
of according to EPA regulations and guidelines.
To accomplish our construction goals and to protect the
environment, which include surface and groundwaters, the DOT
will proceed with the following. details of the remedial
action plan if approved by the NRCD.
EXCAVATION
Material to be excavated as unsuitable will be moved-by
the contractor and disposed of according to contract
specifications.
Those materials found to be contaminated with oil
residue or free product will be separated from normal
unsuitable material. The contaminated soils will' be hauled
on DOT trucks.to an,area..suitable for land treatment or to
the Manteo Sanitary Landfill-for,, fina:l.disposal.
Soil excavated from the area as outlined by grid co-
ordinates N 535, E 795; N 585, E 740; N 585, E 785 will be
separated as contaminated. This area extends 5.0 ft. outside
of the grid coordinates as represented by soil samples # 4,5
and 6. A circular area ten (10.0) ft. in diameter around
grid N 753, E 710 as represented by soil sample number 10,
will be excavated. This material has oil contamination >100
ppm as shown in soil sample analysis. See IEA Report No.
302040, attachment 3 of this remedial action plan. The
volume of this material is.approximately 335 cu. yds above
the water level. An additional 500 cu. yds will be excavated
below waterline to an elevation of (-10) ft. j f this
material is shown to be contaminated in excess of 100ppm of
oil residue, it will be considered as contaminated soil.

CONTAINMENT PROCEDURES
The construction of a cofferdam will be used to enclose
the excavation area. This will prevent any possible free
product or other contaminated materials from entering into
the surface waters. This is a change in the construction
plans that will involve considerable expenditures for the
assured-protection of the environment.
Available on site for spill containment and clean up are
the following:
Water skimmer and 300 ft. of boom
Absorbent materials
14- 85 gal. salvage barrels
1- 10,000 gal. storage tank for sludge oil.
An emergency response team trained in oil spill clean up
is located at Wanchese, within 30 minutes response time.
Skimmed material will be disposed of according to EPA
guidelines.
On-site monitoring will be handled by DOT personnel.
Additional samples and analysis will be performed during
excavation if needed. Further modification of-the
construction plan may be required when approved by the Chief
Engineer.
Approval for the disposal of the contaminated soil has
been given by the Landfill Supervisor for Dare County upon
receipt of a letter from the Chief-Engineer stating content
of contaminated material.
SCHEDULING OF REMEDIAL ACTION PLAN
On or before October 1, 1987, submission of plan to
Natural Resources and Community Development.
The contractor will start excavating the unsuitable
material by October 5 or as soon as the plan is approved by
NRCD. On-site monitoring will be in conjunction with the
contractor doing the excavation. 11

DIVISION OF 'ENVIRONMENTAL MANAGEMENT
GROUNDWATER SECTION
April 1, 1987
MEMORANDUM
TO: Rick Shiver
FROM: Douglass Dixon ?? '
Request For Guidance On Soil Remediation At Sites
Involving Petroleum Fuel Contamination
As a result of•several,recent inquiries from industry of-
ficials, private consultants and Groundwater Section staff, the
following interim guidelines were compiled -in an -effort to
direct site restoret m efforts.
1.43=2In thete nclof a discharge of oil (as defined, by NCGS
the res onsible petroleum fue s). into or upon the land,
and remove the discharge party aandirreesstoreetheuarea undertake
by the
discharge as required by the Oil Pollution and HazardousSub-
stance.,Control Act of.1978. Unless it can be demonstrated that
residual. contamination in the unsaturated zone will not result
in violations of underground water quality standards or
uate an existing.violation, all soil (regolith) containing >100
ppm of total-petroleum fuel hydrocarbons must be excavated: Tn'
situ treatment of contaminated soils using biodegradation or
air purging techniques may be considered as an alternative to
excavation.
.In the absence of areas of obvious contamination (i.e.,
saturated soil, stains, etc.), a good "rule-of-thumb" may be to
require two soil samples from just below the baokfill/native
soil interface and located directly beneath the tank near each
end. Recommended methods for sample preparation include EPA
Method 5030 (purge and trap) for gasoline contamination and EPA
Method 3550 (sonication extraction) for diesel fuel and fuel
oil contamination. Total petroleum fuel hydrocarbons may be
quantified by integrating all major peaks (on the chromatogram)
within the time period in which at least 95t of the recoverable
hydrocarbons are eluted (fe., differentiated).
If feasible, excavated soil (regolith) should
Ict spreading, turning or disking i aeration) on-site

mL ay include delivery to a sanitary landfill, land treatment, or /
backfilling on-site. -1
Prior to transport of contaminated material, it is recom-
mended that the responsible party contact the NC Department of
Human Resources, Solid and Hazardous Waste Management Branch
(S&HWMB) (919-733-2178) to ensure compliance with hazardous.
waste and landfill regulations. A copy of the guidelines is-
sued by the S&HWMB for disposal of oil spill residue was for-
warded to the DEM Regional Supervisors as an attachment to
Perry Nelson's memo of November 7, 1986.
. Land treatment and backfilling require approval of the
regional office of the NC Department of Natural Resources and
Community. Development, Division of Environmental Management.
Based on site-specific conditions, follow-up monitoring may be
required at excavation areas and/or sites selected for land
treatment of the waste material.
If you should have any questions regarding these guide-
lines, please let me know.
