E. Site Characteristics
1. Describe any past releases at this site:
There are no known past releases at this site.
2. Is the facility active or inactive at this time? If the facility is inactive note
the last time the USTs were in operation:
The facility is currently an active television broadcasting station. The 250-
gallon UST had not been'in operation since December 26, 2002. The UST
was removed and replaced by an above ground storage tank (AST).
3. Describe surrounding property use (for example, residential, commercial,
farming, etc.)
The site is located within the Wilmington City Limits and is surrounded by
commercial properties.
4. Describe site geology/hydrogeology:
The site is located within the Peedee Formation of the Cretaceous Coastal
Plain physiographic province. According to the Geologic Map of North
Carolina (Brown, et al., 1985), the Peedee formation is characterized by
locally fossiliferous and calcareous greenish -gray to olive black massive,
glauconitic sand, clayey sand and clay. Patches of sandy molluscan -mold
limestone have been found in the upper part.
4. Describe the results of the receptor survey (water wells, basements, etc.
within 1,500 feet of the facility).
The City of Wilmington currently provides public water to the site and the
surrounding area.
03 =-502543, HIWAYTV3, Tank Closure Report January 2003

A. Describe preparations for closure including the steps taken to notify authorities,
permits obtained and the steps taken to clean and purge the tanks.
The Notification for Permanent Closure (GW/UST-3) was not filed inadvertently
with the North. Carolina Department of Environment and Natural Resources
(NCDENR), Division of Waste Management (DWM), Wilmington Regional
Office. The local fire Marshall was also notified and all proper fire permits were -
obtained.
On December 2.7, 2002, the UST was emptied and purged with dry ice prior to
removal procedures. Oxygen levels inside the UST were measured with a
Neotronics Exotox 40 Portable Gas Monitor. Once an oxygen level lower than
10% was obtained in the tank, the UST was removed. A Site Investigation Report
for Permanent Closure (GWIUST-2) form is included in Appendix A. A Certificate
of Tank Disposal is included in Appendix B.
B. Note the amount of residual material pumped from the tank(s):
The residual material in the tank was removed by WWAY TV 3 for future use in
the new AST.
C. Describe the storage, sampling and disposal of the residual material:
The residual material in the tank was removed by WWAY TV 3 for future use in
the new AST.
D. Excavation
Note: Refer to the "Groundwater Section Guidelines for the Investigation and
Remediation of Soils and Groundwater" on limiting excavations. The Trust Fund
will not pay for excessive excavation unless it is justified and verified by laboratory
results
1. Describe excavation procedures noting the condition of the soils the
dimensions of the excavation in relation to the tanks, piping and/or pumps:
On December 26 and 27, 2002, a backhoe was used to remove the
concrete and soil over and around the UST. The soil surrounding the UST
03-E:E-502543, WWAY TF3, Tank Closure Report, January 2003

did not have a petroleum odor. The dimensions of the diesel UST
excavation was approximately 11.6' x 6.5' x 5.5' .
2. Note the depth of tank burial(s) (from land surface to top of tank):
The UST was buried approximately 2 feet below land surface (bls).
3. Quantity of soil removed:
Soil that was excavated in order to remove the UST did not have a
petroleum odor, and therefore, was used to backfill the excavation.
4. Describe soil type(s):
Soil encountered during the UST removal operations was primarily fill
material. It consisted of yellowish fine sand mixed with coal lumps and
other debris (metal & glass).
5. Type and source of backfill used:
The soil that was removed from the UST pit was reused to backfill the pit
once the tank was removed. Anew concrete pad was poured over the
excavation area.
E. Contaminated Soil
Note: Suspected contaminated soil should be segregated from soil that appears to
be uncontaminated and should be treated as contaminated until proven otherwise
It should not be used as backfill,
1. Describe how it was determined to what extent to excavate the soil:
Soil samples were collected, placed in a polyethylene bag for a minimum of
5 minutes to allow any petroleum hydrocarbons to volatilize, and screened
with an organic vapor analyzer (OVA). Petroleum odors and staining were
also used to determine if contaminated soil. was present. None of the
samples exhibited a petroleum odor.
2. Describe method of temporary storage, sampling and treatment/disposal
of soil:
No soil was removed from the site for treatment/disposal.
03-EKE-502543, WWAYTV 3, Tank Closure Report, January 2003

A. Provide information on field screening and observations, include methods used
to calibrate field screening instrument(s):
Soil samples were collected using a properly decontaminated hand auger and
divided into two representative portions. The first portion of each sample was
placed in a polyethylene bag for a minimum of five minutes to allow any
petroleum hydrocarbons to volatilize. An OVA- was used to screen the
headspace of the bagged sample for volatile hydrocarbons., The OVA is
serviced and calibrated semi - annually by Pine Environmental in Lilburn,
Georgia. OVA readings and depths of soil samples collected are presented in
Table 1. The second portion of each sample was used to submit to the
laboratory for analysis.
B. Describe soil sampling points and sampling procedures used, including:
Note: Refer to the "Groundwater Section Guidelines for the Investigation and
Remediation of Soils and Groundwater" for information about sampling
requirements
On December 27, 2002, five soil samples (S-1 (7.5') through S-5 (4')),
surrounding the UST system were collected using a hand auger, screened with
an OVA, andsubmittedfor laboratory analysis.
Soil sample_ S-1 (7.5') was collected from the bottom of the UST bed and S-2
(4') through S-5 (4') were collected from the walls surrounding the diesel UST
at a depth of approximately-4 feet bls. Figure 2 shows the locations of these
soil samples.
All of the soil samples were submitted for laboratory analysis by EPA method
8015 with sample preparations 5030 (total petroleum hydrocarbons (T H) as
gasoline) and 3550 (total petroleum hydrocarbons (TPH) as diesel).
C. Describe groundwater or surface water sampling procedures used, including:
Note: Refer to the "Groundwater Section Guidelines for the Investigation and
Remediation of Soils and Groundwater" for information about sampling
requirements
Groundwater was not encountered during UST excavation activities.
03-EKE-502j43, WWAYTl13, Tank Closure Report, January 2003

D. Quality -control measures.
Soil samples were immediately placed in laboratory supplied glass containers,
sealed with Teflon lined caps, and placed in an iced cooler. Samples were
maintained at 4°C and submitted under chain -of -custody procedures to
Environmental Conservation Laboratories in Jacksonville, Florida, for
laboratory analysis. Five samples surrounding the UST system were collected
on December 27, 2002, and submitted for laboratory analysis on December 30,
2002.
E. Investigation results
Analytical results indicate TPH as gasoline was detected at concentrations
above the Division of Waste Management (DWM) Reportable Concentration
in all five of the soil samples collected (S-1 (7.5') through S-5 (4')) at
concentrations ranging from 11 milligrams per kilogram (mg/kg) to 16 mg/kg.
Concentrations of TPH as diesel were also detected above the DWM in all five
of the soil samples collected (S-1 (7.5') through S-5 (4')) at concentrations
ranging from 35 mg/kg to 83 mg/kg.
The analytical results are summarized in Table 1, and a copy of the laboratory
analytical report and chain -of -custody form is included in Appendix C.
03 ECE-502543, WWAY TV 3, Tank Closure Report, January 2003

Analytical results indicate TPH. as gasoline and diesel were detected at
concentrations above the NCDWM Reportable Concentration in all five of soil
samples collected -from around the UST system at WWAY TV 3 Station in
Wilmington, North Carolina, during the UST closure activities.
