Mr. Rudy Ball, President
G.N.C. Energy Corporation
15700 Dixie Highway
Telephone 502-937-1700 (KY)
Louisville, KY 40272
(May use Chimney Rock Rd.
address)
2. Date of Investigation: September 25, 1990
3. Report Prepared by: A.R. Hagstrom, Environmental Engineer,
DEM, WSRO, WQ
4. Persons Contacted and Telephone Number:
Mr. Johnny Burchell, Terminal Manager (919) 299-1551
Mr. John M. Stewart, Consultant, Bain and Palmer Inc. (919)
272-9713
5. Directions to Site:
Go to the junction of US421 (West Market Street) and Chimney
Rock Road. The facilities are to the immediate southwest of
this intersection on Chimney Rock Road
6. Discharge Points - 001 (Northwest) - Delete
002 (Southwesta (Combining with 001)
Latitude: 36 4' 28"
Longitude: 790 55, 11" 930
Attach a USGS Map Extract and indicated treatment plant site
and discharge point on map.
USGS Quad No. C19SW or USGS Quad Name Guilford
7. Size (land available for expansion and upgrading):
The land area is approx. 11.5 acres and is graded to suit
the terminal layout. There is some land that could be used
for upgraded treatment systems.

October $, 1990
8. Topography (relationship to flood plain included):
The site is essentially graded to suit the office, tank and
tanker loading, distillation unit, storage, and spill
prevention systems. Over-all it slopes to the South from 1
to 5% slopes. The storage tanks are diked and much of the
site is fenced.
9. Location of nearest dwelling:
Nearest residence is over 1000 feet from the terminal.
Numerous other businesses are near -by.
10. Receiving stream or affected surface waters: Upon
discharge the water travels via open storm drainage ways and
surface ditches to a U.T. to East Fork Deep River. The
releases are rain dependent.
a. Classification: WS-III
b. River Basin and Subbasin No.: 030608 Cape Fear
C. Describe receiving stream features and pertinent
downstream uses: This drainage joins the discharges
from several other terminals within approx. 500 feet and
then additional terminals in the UT to East Fork Deep
River. Just South of I-40 these discharges flow through
two lakes (with separators) at Colonial Pipeline's
facility. From the Colonial ponds the UT travels
through urban and rural areas.
PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
1. Type of wastewater: 0 % Domestic
100% Industrial
a. Volume of Wastewater: Unknown, small amounts of product
and product residue are diluted by rain water. The
volumes of water released is rainfall dependent and
intermittent.
b. Types and quantities of industrial wastewater:
Oil, kerosene, and unleaded product contaminated
water (low concentrations) from spills, large or small,
that occur during terminal operations including tanker
loading and unloading, water drainage from storage
tanks, and from terminal distillation operations. Tank
bottoms are removed under contract as hazardous wastes.
Discharges pass through oil/water separators or tanks,
before water is released to the diked areas. Water
contacting products goes through one or more separators
before discharges.

c. Prevalent toxic constituents in wastewater:
Hydrocarbons, phenols, and additives for fuels.
d. Pretreatment Program (POTWs only)
N/A
in development approved
should be required not needed
2. Production rates (industrial discharges only) in pounds
N/A
a. highest month in the last 12 months
b. highest year in last 5 years
3. Description of industrial process (for industries only) and
applicable CFR Part and Subpart: Unloading of tankers with
transmix and other mixes, oil, kerosene, and gasoline
storage tank farm and dispensing of the products to tankers,
and distillation operations to separate "Transmix" and other
available mixed products. They convert various mixed
products to usable products.
4. Type of treatment (specify whether proposed or existing):
Oil/water separators from tanker loading area, and oil/water
separators at tanks for water removal from process areas.
Evaporation from diked holding areas. Valved releases with
measured flows (estimated).
5. Sludge handling and disposal scheme:
Tank bottoms are treated as hazardous wastes and are handled
by contractors.
6. Treatment plant classification:
7. SIC Code(s) 5171
Wastewater Code(s) 37, 38, 39
PART III - OTHER PERTINENT INFORMATION
1. Is this facility being constructed with Construction Grants
Funds (municipals only)? No
2. Special monitoring requests: Same as other terminals in the
Greensboro area discharging to East Fork Deep River.
3. "Additional effluent limits requests:

NCO074241
October B, 1990
4. Other: This terminal appears to be clean and adequately
operated. The wastewater discharges all go through property
of other terminals and .become a part of those and other
downstream terminals' discharges. At this point, this is
one of eleven (11) discharges going into the East Fork Deep
River through the Colonial Pipeline Company's ponds (each of
which has oil/water separation). The upper Discharge 001
can be easily diverted to an adjacent diked area that
discharges- to another dike system and to Discharge 002.
PART IV - EVALUATION AND RECOMMENDATIONS
The WSRO recommends that an NPDES be re -issued with a sincle
discharge point, but only after the Groundwater Quality Section
and the Division of Health Services has had an opportunity to
comment on the Permit. This facility has existed and the
facility has been discharging for many years. The following
items should be considered:
1. All discharges and daily flows for each discharge should be
reported. The discharge point should be designated as 002
for the Southwest Discharge that will now include the former
Discharge 001.
2. Phenols shall be reported in concentration units and in
lbs/day. Concentration analyses should not be required more
than twice per month per discharge point.
3. All permits for Terminals discharging into the Colonial
Pipeline Ponds should have the same limits.
4. Any toxicity sampling shall be done just prior to or during
discharges. The tests should be of limited duration if
toxicity problems are not present.
5. Sampling frequency should consider the rain dependence and
consistent nature of the discharges.
