RALEIGH
RECYCLE SYSTEM PERMIT
In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as
amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
Aspect Minerals, Incorporated
Mitchell County
FOR THE
continued operation of a 18,000 GPD wastewater recycle system consisting of a filter press, three (3)
inorganic solids settling ponds in parallel, a large fine settling basin, a 200 GPM return water pump, a
5,000 gallon pressurized storage tank, a chemical feed system, and all associated piping, valves, controls
and appurtenances to serve the Bear Creek Plant with no discharge of wastes to the surface waters,
pursuant to the renewal request received December 29, 1994, 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 February 28, 2000, shall void Permit
No. WQ0003699 issued October 14, 1993, and shall be subject to the following specified conditions and
limitations:
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
A � 4-
uaL.a.
2. This permit is effective only with respect to the nature and volume of wastes described in
the application and other supporting data.
3. The facilities shall be properly maintained and operated at all times.
4. 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 the request will be considered on its merits and may or may
not be approved.
5. In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective action, including those
actions that may be required by this Division, such as the construction of additional or
replacement treatment or disposal facilities.

19. Noncompliance Notification:
The Permittee shall report by telephone to the Asheville Regional Office, telephone number
[phone], as soon as possible, but in no case more than 24 hours or on the next
working day following the occurrence or first knowledge of the occurrence of any of the
following:
a. Any occurrence at the wastewater treatment facility which results in the treatment of
significant amounts of wastes which are abnormal in quantity or characteristic, such as
the dumping of the contents of a basin or tank, 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 renders 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; or
d. Any time that self-monitoring information indicates that the facility is not in 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.
20. Upon classification of the facility by the Certification Commission, the Permittee shall
employ a certified wastewater treatment plant operator to be in responsible charge (ORC) of
the wastewater treatment facilities. The operator must hold a certificate of the type and
grade at least equivalent to or greater than the classification assigned to the wastewater
treatment facilities by the Certification Commission. The Permittee must also employ a
certified back-up operator of the appropriate type and grade to comply with the conditions
of Title 15A, Chapter 8A, .0202. The ORC of the facility must visit each Class I facility at
least weekly and each Class II, III, and IV facility at least daily, excluding weekends and
holidays, and must properly manage and document daily operation and maintenance of the
facility and must comply with all other conditions of Title 15A, Chapter 8A, .0202.
21. 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.
