Dear Mayor Evans:
In accordance with your application received December 29, 1995, we are forwarding herewith
Permit No. WQ0004728 dated March 15, 1996, to the Town of Fremont for the continued operation of the
subject wastewater treatment and spray irrigation facilities. It is understood the Town of Fremont is under
an SOC and plans to take the subject wastewater treatment and spray irrigation facilities off line and
completely out of service on or before December 1, 1998. Please note a permit renewal must be requested
I80 days prior to the expiration of this permit if these facilities are not out of service by the expiration date.
The pretreatment requirements for the Town of Fremont are located in Permit Section III. The

compliance with its permit Iimitations.
Persons reporting such occurrences by telephone shall also file a written report in letter

V . GROUNDWATER REQUIREMENTS
1. The four (4) existing monitor wells No. 1, No. 2, No. 3, and No. 4, shall be sampled
every March, July, and November for the following parameters:
NO3
Ammonia Nitrogen
TDS
TOC
pH
Water Level
Chloride
Fecal Coliforms
Cadmium
Lead
Chromium
Nickel
Cyanide
Volatile Organic
Compounds - In November only (by the method below)
Method 6230D (Capillary - Column), "Standard Methods For The Examination of
Water and Wastewater", 17th ed., 1989
The measurement of water levels must be made prior to sampling for the remaining
parameters. The depth to water in each well shall be measured from the surveyed point on
the top of the casing.
The measuring points (top of well casing) of all monitoring wells shall be surveyed to
provide the relative elevation of the measuring point for each monitoring well.
If TOC concentrations greater than 10 mg/l are detected in any downgradient monitoring
well, additional sampling and analysis must be conducted to identify the individual
constituents comprising this TOC concentration. If the TOC concentration as measured in
the background monitor well exceeds 10 mgli, this concentration will be taken to represent
the naturally occurring TOC concentration. Any exceedances of this naturally occurring
TOC concentration in the downgradient wells shall be subject to the additional sampling
and analysis as described above.
If any volatile organic compounds are detected by method 6230D, then the Washington
Regional Office groundwater supervisor (phone number 9191946-6481) must be contacted
immediately for further instructions regarding any additional follow-up analyses required.
The results of all initial and follow-up analyses must be submitted simultaneously.
The results of the sampling and analysis shall be sent to the Groundwater Section, Permits
and Compliance Unit, P.O. Box 29578 Raleigh, N.C. 27626-0578 on Form GW-59
[Compliance Monitoring Report Form] every April, August, and December.
3. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall
be provided.
4. The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in
15A NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary
for the disposal system constructed prior to December 31, 1983 is established at either (1)
500 feet from the waste disposal area, or (2) at the property boundary, whichever is closest
to the waste disposal area. An exceedance of Groundwater Quality Standards at or beyond
the Compliance Boundary is subject to immediate remediation action in addition to the
penalty provisions applicable under General Statute 143-215.6A(a)(1).
In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the
disposal systems midway between the Compliance Boundary and the perimeter of the
waste disposal area. Any exceedance of standards at the Review Boundary shall require
remediation action on the part of the permittee.
VI. INSPECTIONS
1. Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to
insure proper operation of the subject facilities.
2. The Permittee or his designee shall inspect the wastewater treatment and disposal facilities
to prevent malfunctions and deterioration, operator errors and discharges which may cause
or lead to the release of wastes to the environment, a threat to human health, or a nuisance.
The Permittee shall keep an inspection log or summary including at least the date and time
of inspection, observations made, and any maintenance, repairs, or corrective actions taken
by the Permittee. This log of inspections shall be maintained by the Permittee for a period
of three years from the date of the inspection and shall be made available upon request to
the Division of Environmental Management or other permitting authority.
3. Any duly authorized officer, employee, or representative of the Division of Environmental
Management may, upon presentation of credentials, enter and inspect any property,
premises or place on or related to the disposal site or facility at any reasonable time for the
purpose of determining compliance with this permit, may inspect or copy any records that
must be maintained under the terms and conditions -of this permit, and may obtain samples
of groundwater, surface water, or leachate.
VII. GENERAL CONDITIONS
1. This permit shall become voidable unless the facilities are constructed in accordance with
the conditions of this permit, the approved plans and specifications, and other supporting
data.
2. This permit is effective only with respect to the nature and volume of wastes described in
the application and other supporting data.
0
3. This permit is not transferable. In the event there is a desire for the facilities to change
ownership, or there is a name change of the Permittee, a formal permit request must be
submitted to the Division of Environmental Management accompanied by an application
fee, documentation from the parties involved, and other supporting materials as may be
appropriate. The approval of this request will be considered on its merits and may or may
not be approved.
4. Failure to abide by the conditions and limitations contained in this permit may subject the
Permittee to an enforcement action by the Division of Environmental Management in
accordance with North Carolina General Statute 143-215.6(a) to 143-215.6(c).
5. The issuance of this permit does not preclude the Permittee from complying with any and
all statutes, rules, regulations, or ordinances which may be imposed by other government
agencies (local, state, and federal) which have jurisdiction.
6. A set of approved plans and specifications for the subject project must be retained by the
Permittee for the life of the project.
7. The annual administering and compliance fee must be paid by the Permittee within thirty
(30) days after being billed by the Division. Failure to pay the fee accordingly may cause
the Division to initiate action to revoke this permit as specified by 15A NCAC 2H .0205
(c)(4).
S. The Permittee, at least six (6) months prior to the expiration of this permit, shall request its
extension. Upon receipt of the request, the Commission will review the adequacy of the
facilities described therein, and if warranted, will extend the permit for such period of time
and under such conditions and limitations as it may deem appropriate.
