Subject: Permit No. WQ0006317

Wastewater Spray Irrigation
Guilford County
Dear Mr. Norris:
On September 25, 1992, the Division of Environmental Management issued Permit No.
WQ0006317 to Colonial Pipeline Company for the continued operation of the subject wastewater spray
irrigation facilities and for the construction of an air stripping unit to precede the aeration lagoon. On
November 6, 1992, the Division received a "Petition for a Contested Case Hearing" from Colonial
Pipeline Company objecting to some of the conditions and requirements in Permit No. WQ0006317,
which was issued on September 25, 1992. On November 10, 1992, staff from the Division of
Environmental Management met with representatives of Colonial Pipeline to discuss Colonial's concerns.
As a result of this meeting and the Division's review of the concerns which were expressed, the Division
has modified the permit where appropriate and has given you the opportunity to review a draft permit. A
summary of the objections raised by Colonial Pipeline Company and the Division's position on those
objections is contained below:
Objection 1: Colonial requests clarification that the 100 foot buffer requirement specifed in conditions
I.6.c and I.6.f does not apply to monitoring wells.
Response l: Conditions I.6.c and I.61 have been modified by adding a phrase to indicate that the
buffers do not apply to groundwater monitoring wells.
Objection 2: Colonial requests clarification that condition I.6.d will not prohibit the use of spray field 1,
even though a previously existing wet weather ditch is within 100 feet of the spray field.

Response 2: The following sentence: "Unless any of the situations, described above in this paragraph,
occur, the buffers that were applicable at the time of the facility design will continue to be
applicable"; has been added to the note in condition 1.6 as clarification.
Objection 3: Colonial requests that total coliforms be deleted from the effluent monitoring requirements
in condition III.3.
Response 3: Condition 111.3 has been modified accordingly since this wastewater is industrial.
Objection 4: Colonial states that monitoring well MW-lA is upgradient of spray heads 1-6 and is,
therefore, not likely to be the source of low level contamination in this well. Colonial
believes that the source of contamination can be attributed to some formerly used sludge
disposal pits, which they have started remediating.
Response 4: The Division agrees that MW-lA is located upgradient of the spray field. Therefore,
condition IV.1 has been deleted.
Objection 5: Colonial requests that total coliforms, TOC, and the use of EPA Method 601 be deleted
from condition IV.2.
Response 5: Since the Division agrees that these parameters would not provide useful groundwater data,
condition IV.2 has been modified accordingly.
Objection 6: Colonial requests that the compliance and review boundaries be corrected.
Response 6: A revised map is included with the permit.
In accordance with the request for two modifications to the draft permit that was transmitted to you
on January 20, 1993, and Colonial Pipeline Company's subsequent acceptance of the draft with those two
modifications, this permit shall be final and binding from the date of issuance until August 31, 1997, shall
void Permit No. WQ0006317, which was issued on September 25, 1992, and be shall be subject to the
conditions and limitations as specified therein. If you have not already done so, please execute the
attached Notice of Withdrawal.
If you need additional information concerning this matter, please contact Mr. Randy Jones at 919/

Colonial Pipeline Company with no discharge of wastes to the surface waters, pursuant to the application
received on March 27, 1992, and the "Petition for a Contested Case Hearing " received on November 6,
1992, and in conformity with the project plan, specifications, and other supporting data subsequently filed
and approved by the Department of Environment, Health, and Natural Resources and considered a part of
this permit.
This permit shall be effective from the date of issuance until August 31, 1997, shall void Permit
No. WQ0006317, which was issued on September 25, 1992, and shall be subject to the following
specified conditions and limitations:
• f'WMIM, 01 .► 1
1. Upon completion of construction and prior to operation of the air stripping unit, a
certification must be received from a professional engineer certifying that the air stripping
unit has been installed in accordance with this permit, the approved plans and
specifications. Mail the Certification to the Permits and Engineering Unit, P.O. Box
29535, Raleigh, NC 27626-0535.
2. The spray irrigation facilities shall be effectively maintained and operated at all times so
that there is no discharge to the surface waters, nor any contamination of ground waters
which will render them unsatisfactory for normal use. In the event that the facilities fail to
perform satisfactorily, including the creation of nuisance conditions or failure of the
irrigation area to adequately absorb the wastewater, the Permittee shall take such immediate
corrective action to correct the problem, including actions as may be required by the
Division of Environmental Management.

3. The issuance of this permit shall not relieve the Permittee of the responsibility for damages
to surface or groundwaters resulting from the operation of this facility.
4. The sludge generated from these treatment facilities must be disposed of in accordance with
General Statute 143-215.1 and in a manner approved by the North Carolina Division of
Environmental Management.
5. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.
b. The following buffers shall be maintained:
a) 400 feet between wetted area and any residence or places of public assembly under
separate ownership,
b) 150 feet between wetted area and property lines,
c) 100 feet between wetted area and wells (does not apply to monitoring wells),
d) 100 feet between wetted area and drainageways or surface water bodies,
e) 50 feet between wetted area and public right of ways,
f) 100 feet between wastewater treatment units and wells (does not apply to
monitoring wells),
g) 50 feet between wastewater treatment units and property lines.
Some of the buffers specified above may not have been included in previous permits for
this waste treatment and disposal system. These buffers are not intended to prohibit or
prevent modifications, which are required by the Division, to improve performance of the
existing treatment facility. These buffers do, however, apply to modifications of the
treatment and disposal facilities which are for the purpose of increasing the flow that is
tributary to the facility. These buffers do apply to any expansion or modification of the
spray irrigation areas and apply in instances in which the sale of property would cause any
of the buffers now complied with, for the treatment and disposal facilities, to be violated.
Unless any of the situations that are described above in this paragraph, occur, the buffers
that were applicable at the time of the facility design will continue to be applicable. The
applicant is advised that any modifications to the existing facilities will require a permit
modification.
II. OPERATION AND MAINTENANCE REQUIREMENTS

significant amounts of wastes which are abnormal in quantity or characteristic, such
as the dumping of the contents of a sludge digester; the known passage of a slug of
hazardous substance through the facility; or any other unusual circumstances.
b. Any process unit failure, due to known or unknown reasons, that render the facility
incapable of adequate wastewater treatment such as mechanical or electrical failures
of pumps, aerators, compressors, etc.
C. Any failure of a pumping station, sewer line, or treatment facility resulting in a by-
pass directly to receiving waters without treatment of all or any portion of the
influent to such station or facility.
d. Any time that self -monitoring information indicates that the facility has gone out of
compliance with its permit limitations.
Persons reporting such occurrences by telephone shall also file a written report in letter
form within 15 days following first knowledge of the occurrence. This report must outline
the actions taken or proposed to be taken to ensure that the problem does not recur.

The six (6) existing monitor wells (please note that MW-1A is being replaced with MW-
1B) must be sampled every March, July, and November for the following parameters:
NO3 TDS
pH Ammonia Nitrogen
Water Level Chlorides
Total Suspended Solids
Volatile Organic Compounds using EPA Method 602.
The measurement of water level must be made prior to sampling for the remaining
parameters.
The measuring points (top of well casing) of all monitoring wells shall be surveyed to
provide relative elevations of the measuring point for each of the monitoring wells. The
depth of water in each well shall be measured from the surveyed point on the top of the
casing.
The results of the sampling and analysis shall be sent to the N.C. Division of
Environmental Management on Form GW-59 (Compliance Monitoring Report Form) every
April, August, and December.
2. The Compliance Boundary delineated on the attached site map for the disposal system is
specified by regulations in 15 NCAC 2L, Classifications and Water Quality Standards
applicable to the groundwater of North Carolina. An exceedance of Groundwater Quality
Standards beyond the Compliance Boundary is subject to penalty provisions applicable
under General Statute 143-215.6A. The sale of property, by the Permittee, which is within
or contiguous to the disposal system site may alter location of the Compliance Boundary.
For facilities permitted on or after December 30, 1983, the Compliance Boundary is
established at the lesser of 250 feet from the perimeter of the disposal field, or 50 feet
within the property boundary.
5

If the title to any property which may affect the location of the Compliance Boundary is
changed, the permittee shall notify the Division Director within 14 days. The Director shall
then establish a modified Compliance Boundary which will be done as a modification to the
Permit.
The REVIEW BQJMARY delineated on the attached site map for the disposal system is
specified by regulations in 15 NCAC 2L, Groundwater Classifications and Standards. A
REVIEW BOUNDARY is established around disposal systems midway between the
Compliance Boundary and the perimeter of the waste disposal area. When the
concentration of any substance equals or exceeds the maximum allowable concentration of
that substance at the REVIEW BOUNDARY, as determined by monitoring, the permittee
shall either (i) demonstrate, through predictive calculations or modeling, that natural site
conditions, facility design and operational controls will prevent a violation of standards at
the Compliance Boundary; or, (ii) submit a plan for the alteration of existing site
conditions, facility design or operational controls that will prevent a violation of standards
at the Compliance Boundary, and implement that plan upon im approval by the Director.
3. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall
be provided.
V . INSPECTIONS
1. Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to
insure proper operation of the subject facilities.
